| How Can I add a cell double click event in PyQt5 Posted: 01 Jul 2021 09:21 AM PDT I'm trying to add an on double click event to the table on my PyQt app, I'm not extremely clear on how signals work. Currently when I run this code and navigate to where the table will be generated, I am met with an error that reads: "TypeError: native Qt signal is not callable" I have the following things imported: import sys import os import PyQt5 from PyQt5 import QtWidgets as qtw from PyQt5.QtWidgets import QTableWidget,QTableWidgetItem from PyQt5 import QtGui
The Table is generated just fine, until I try to add the event: def makeTable(self, dataSet, layout): cols = len(dataSet[0]) #columns rows = len(dataSet) #rows table = qtw.QTableWidget() table.setRowCount(rows) table.setColumnCount(cols) for i in range(len(dataSet)): for j in range(len(dataSet[i])): table.setItem(i,j, QTableWidgetItem(dataSet[i][j])) table.cellDoubleClicked(i, j).connect(self.cellClick(i, j, dirList, layout)) #<-Line In Question layout.addWidget(table)
Current Test cellClick Function to test that the double click works: def cellClick(self, r, c, dirList, layout): print('here: ', r, ' ', c)
Note: I appologize for this not exactly being a "Minimum reproducible example", but I tried to include as little code as possible, especially because I'm fairly certain the issue is very small and has to do with my syntax. Thank you and please let me know if I need to make any edits.  |
| Starshipit / DHL DEC does not import "commodity_code" from product Posted: 01 Jul 2021 09:20 AM PDT We are using DHL Express for shipping about half our orders. We have been using a magento extension for creating labels for a few years now. Since starting from this month it is a requirement to add HS codes to all order items we have been asked to move to DEC, which is a DHL branded version of starshipit. According to their customer service, all that is needed to do is to add the field "commodity_code" as a product attribute and it will be automatically be imported. But that is not the case. Starshipit support reported that the "commodity_code" fields appears "null" at the api. I have added a HS code to all products, so the issue must be with the api. Support says that if I can show them a way that this custom attribute can be called from api they will make it happen for us. Now the question is: How can this be done? I have no idea and really need to get this to work. Any advise is appreciated!!! We are using magento 1.9.3.2  |

| accessing methods of an object Posted: 01 Jul 2021 09:20 AM PDT First up some information about the system: - PHP 7.4
- WordPress 5.7.2
- WooCommerce 5.4.1
- Germanized for WooCommerce 3.5.0 Github
- Germanized for WooCommerce pro 3.2.3
I can't use WP_DEBUG, var_dump or echo unfortunately. I use the "Germanized" plugin for the shipping provider DHL and other things but the problem is with DHL.
I am trying to set the customerReference on the label to the items that are inside. The good thing is, there is a filter for that so I wrote this in the functions.php in my child-theme: <?php ...other stuff... add_filter( 'woocommerce_gzd_dhl_label_customer_reference', 'addItemsToLabelReference', 10, 3 ); function addItemsToLabelReference($ref, $label, $shipment ) { return $ref; } ?>
This code would just return the reference as it comes from the plugin. I can however access the $shipment object to retrieve the items.
I am able to call get_items() to get an array of ShipmentItems.
The problem starts when I want to get the sku. When I loop through the array with a foreach loop and I call get_sku the website just crashes and doesn't work anymore. I think this is more a PHP issue than a WooCommerce issue.
The code I tried is this: function addItemsToLabelReference($ref, $label, $shipment ) { foreach($shipment->get_items() as $item){ $sku = $item->get_sku(); $quantity = $item->get_quantity(); } return $ref }
The source code for the $item class can be found here
I'm afraid I don't have an error message/code, I just get the White-Screen-of-Death. Thanks for the help in advance!  |

| Prevent macOS from populating application's "View" menu with its own options Posted: 01 Jul 2021 09:21 AM PDT While we're writing Mac App and populating the macOS (top)menu-bar with our application-specific options, we noticed macOS adds a few of its own options at runtime, in the "View" menu: - Show Tab Bar
- Enter Full Screen
While these macOS' added options do nothing(when clicked) we found it's difficult to remove them as well since they seem to be get added during the "View" menu opening. The only option we found is alter the menu label to something but "View", that prevents macOS from populating its own items in the menu. But we generally don't like to change the label "View". Is there any way or entitlement is available by using which we can prevent macOS from populating in the "View" menu?  |
| TypeScript conditional return type based on return value? Posted: 01 Jul 2021 09:21 AM PDT I have this code: type SuccessResponse = { success: true; image: string; }; type FailResponse = { success: false; message: string; }; type OpenGraphScraperResponse = SuccessResponse | FailResponse; export const useOpenGraphScraper = (text: string, guid: string) => { return useQuery(['og', guid], () => { return axios .get<OpenGraphScraperResponse>(`/api/open-graph-scraper?content=${text}`) .then((res) => res.data); }); };
I like the return type to be SuccessResponse whenever the data returned contains success: true and FailResponse whenever it's success: false. In my template, I want to access the image property so I did it like this: <div v-if="result.success"> <img :src="result.image" /> </div>
Even though I wrapped it inside a condition where it should only render the img element when success: true, TypeScript still complains: Property 'image' does not exist on type 'SuccessResponse | FailResponse'. Property 'image' does not exist on type 'FailResponse'.

| How to combine rows in a dataframe in a pairwise fashion while applying some function Posted: 01 Jul 2021 09:20 AM PDT I have a dataframe that stores keys as ID, and some numerical values in Val1/Val2: ID Val1 Val2 id0 10 20 id0 11 19 id1 5 5 id1 1 1 id1 2 4
I would like to go over this dataframe and combine the rows pairwise while getting the averages of Val1/Val2 for rows with the same ID. A suffix should be appended to the new row's ID based on which number pair it is. Here is the resulting dataframe: ID Val1 Val2 id0_1 10.5 19.5 id1_1 3 3 id1_2 1.5 2.5
In this example, there are only 3 rows left. (id0, 10, 20) gets averaged with (id0,11,19) and combined into one row. (id1,5,5) gets averaged with (id1,1,1,) and (id1,1,1) gets averaged with (id1,2,4) to form 2 remaining rows. I can think of an iterative approach to this, but that would be very slow. How could I do this in a proper pythonic/pandas way? Code: df = pd.DataFrame(columns=['ID', 'Val1', 'Val2'], data=[['id0', 10, 20], ['id0', 11, 19], ['id1', 5, 5], ['id1', 1, 1], ['id1', 2, 4]])

| Convert String Array to int using JOptionPane Posted: 01 Jul 2021 09:21 AM PDT I'm doing a train ticket program. I want to convert certain text in the string array to a certain price using JOptionPane. ex. String[] option_1 = {"location1","location2", "location3","location4","location5"};
where location1 = $10, location2 = $23, etc. all I know is I could use Interger.parseInt or double, but I don't know where to go next. Should I go with a loop or make a whole new array and make it equal to the string array. I'm wondering if there is a more easier method to execute this. code : public static void main (String [] args) { String name; String[] option_1 = {"North Avenue","Quezon Avenue", "Kamuning","Cubao","Santolan","Ortigas","Shaw","Boni","Guadalupe","Buendia","Ayala","Magallanes","Taft"}; String[] option_2 = {"North Avenue","Quezon Avenue", "Kamuning","Cubao","Santolan","Ortigas","Shaw","Boni","Guadalupe","Buendia","Ayala","Magallanes","Taft"}; name = JOptionPane.showInputDialog("Welcome to DME Ticketing System!\n\nEnter your name:"); String leave = (String)JOptionPane.showInputDialog(null, "Leaving from", "Train Station", JOptionPane.QUESTION_MESSAGE, null, option_1, option_1[0]); String going = (String)JOptionPane.showInputDialog(null, "Leaving from", "Train Station", JOptionPane.QUESTION_MESSAGE, null, option_2, option_2[0]); // int pay = (Integer)JOptionPane.showInputDialog(null, "From: "+leave+"\nTo: "+going+"\nFare Price: "+"\n\nEnter your payment amount:", // null, JOptionPane.PLAIN_MESSAGE, null, null,null); // int op1 = Integer.parseInt(going); // int op2 = Integer.parseInt(leave); JOptionPane.showMessageDialog(null, "DME Ticketing System\nMalolos, Bulacan\n\n" + "Name: "+name +"\nLocation: "+leave +"\nDestination: "+going +"\nFare: " +"\nPayment: "//+pay +"\nChange: " , "RECEIPT",JOptionPane.INFORMATION_MESSAGE); }

Normally program returns info or interact when dns info is polled. If a DNS query for certain domain is called, the sender of the dns response will be changed. If not normall dns infor will be sent. When code execution is monitored the dns_responder(local_ip: str) gets called. The call for get_response whithin does not take place. To trigger the dns_responder methode, I use ping "domainname" and nslookup "domainname". Am i overseeing something? I can recall this code works correctly. Can someone have a look what i missed? For me get_response attribute is not triggered.  |
| Extract key value from free text using Regex Posted: 01 Jul 2021 09:22 AM PDT Let's say I have this free text unitType:unit_failure;unitId:b7eb;unitTitle:L1-O VEN_ACC_SETTINGS>(30s)>EXCL(A);applicable:true;comment:Decline sender:SELLER;Decline reason:VEN_ACC_SETTINGS;triggered by user:495259708;Display reason: CON_FAILURE;modified by: log_res_mon
I want to extract the values into an object that has the same property names. public class Values { public string UnitType { get; set; } public string UnitType { get; set; } public string UnitTitle { get; set; } public string Applicable { get; set; } public string DeclineSender { get; set; } public string DeclineReason { get; set; } public string TriggeredByUser { get; set; } public string DisplayReason { get; set; } public string ModifiedBy { get; set; } }
so far I tried this code: string comment = "unitType:unit_failure;unitId:b7eb;unitTitle:L1-O VEN_ACC_SETTINGS>(30s)>EXCL(A);applicable:true;comment:Decline sender:SELLER;Decline reason:VEN_ACC_SETTINGS;triggered by user:495259708;Display reason: CON_FAILURE;modified by: log_res_mon"; string regex = @"(.*?:\s*)(\w*);?"; var matches = Regex.Matches(comment, regex);
Which almost worked. but you can see that unitTitle was cut after L1-. Another thing, comment: is an exception that can be dropped either by the expression, or I can simply drop it using .Replace. 
How do I fix the expression to include the full value of unitTitle and to drop comment: (You can tell me it is easier to use .Replace)? What is the best way to extract the values from matches and fill them in the object? EDIT: I tried this, but it is really ugly, is there a better way? (Ignore that I'm using anonymous object, that is just for testing now). var obj = new { unitType = matches.Single(x => x.Groups[1].Value == "unitType").Groups[2].Value };

I have the history of the maintenance that is done regulary, and the state of each component. the time series dataset and the history of the failure. history of the maintenance' columns : ----------------------------------------------------------- Equipements |component's state | Date | Type of maintenance ----------------------------------------------------------
I have search and I fount a lot of model such as HMM or LSTM OR MMMM or (POMDP that I can use to solve the problem, but what Im finding hard to do is how can I build one model for the all 1000 devices.  |
| How do you evaluate z = x-- == y + 1; Posted: 01 Jul 2021 09:21 AM PDT given that int w = 1; int x = 6; int y = 5; int z = 0; z = !z || !x && !y; printf("%d\n", z); z = x-- == y + 1; printf("%d\n", z);
Could someone explain how the line below would evaluate to 1 if x-- is 5 and y+1 is 6? z = x-- == y + 1;

| Swift UI list not updating on Cloudkit sync Posted: 01 Jul 2021 09:20 AM PDT I am trying to create a simple application that leverages CloudKit to sync between multiple iOS devices (via iCloud) and possibly macOS devices (still via iCloud). Problem: I have a core data entity which seems to work great locally in my app. When I switch to using Cloudkit I am unable to see changes on another device without closing/reopening the app. I am using the Cloudkit template in Xcode with the SwiftUI lifecycle. ie, PersistenceController and managed object context. I think this is a view not refreshing issue, but am not 100% sure. Once the app on a different device is closed and reopened then it loads the new data successfully. This applies to additions and deletes. Testing: I have tested this using Testflight as well as running two simulators locally. Code: PersistenceController.swift import CoreData struct PersistenceController { static var shared = PersistenceController() static var preview: PersistenceController = { let result = PersistenceController(inMemory: true) let viewContext = result.container.viewContext for i in 0..<10 { let newItem = Card(context: viewContext) newItem.cardValue = String(i) newItem.cardOrder = Int32(i) } do { try viewContext.save() } catch { // Replace this implementation with code to handle the error appropriately. // fatalError() causes the application to generate a crash log and terminate. You should not use this function in a shipping application, although it may be useful during development. let nsError = error as NSError fatalError("Unresolved error \(nsError), \(nsError.userInfo)") } return result }() //Is this needed? lazy var updateContext: NSManagedObjectContext = { let _updateContext = NSManagedObjectContext(concurrencyType: .privateQueueConcurrencyType) _updateContext.parent = PersistenceController.shared.updateContext return _updateContext }() let container: NSPersistentCloudKitContainer init(inMemory: Bool = false) { container = NSPersistentCloudKitContainer(name: "Cards") if inMemory { container.persistentStoreDescriptions.first!.url = URL(fileURLWithPath: "/dev/null") } container.loadPersistentStores(completionHandler: { (storeDescription, error) in if let error = error as NSError? { fatalError("Unresolved error \(error), \(error.userInfo)") } }) container.viewContext.automaticallyMergesChangesFromParent = true container.viewContext.mergePolicy = NSMergeByPropertyObjectTrumpMergePolicy } }
ContentView.swift import SwiftUI import CoreData struct ContentView: View { @Environment(\.managedObjectContext) var managedObjectContext @FetchRequest(entity: Card.entity(), sortDescriptors: [NSSortDescriptor(key: "cardOrder", ascending: true)]) var cards: FetchedResults<Card> var body: some View { NavigationView { VStack { Text("Scrum +") .font(.largeTitle) .fontWeight(.regular) Spacer() List(cards, id: \.id) {card in NavigationLink(destination: PointRow(card: card)) { PointRow(card: card) } } Spacer() NavigationLink(destination: SettingsView().environment(\.managedObjectContext, self.managedObjectContext) ) { Text("Card Settings") } .padding(.bottom) } } } }
SettingsView.swift (where saving/deleting/reordering happens) import SwiftUI struct SettingsView: View { @State private var editMode = EditMode.inactive @State private var showModal = false @Environment(\.managedObjectContext) var managedObjectContext @FetchRequest(sortDescriptors: [NSSortDescriptor(key: "cardOrder", ascending: true)]) var cards: FetchedResults<Card> var body: some View { VStack { Text("Card Values") .font(.largeTitle) HStack { EditButton() .padding(.leading) Spacer() addButton .padding(.trailing) } .padding(.vertical) List { ForEach(cards) { item in Text(item.cardValue!) } .onDelete(perform: onDelete) .onMove(perform: onMove) .environment(\.editMode, $editMode) } .sheet(isPresented: $showModal) { //Show the view to add a new card. SettingsModal(showModal: self.$showModal, numberOfCards: cards.count).environment(\.managedObjectContext, self.managedObjectContext) } } } private var addButton: some View { switch editMode { case .inactive: return AnyView(Button(action: onAdd) { Image(systemName: "plus") }) default: return AnyView(EmptyView()) } } func onAdd() { showModal = true } func onDelete(indexSet: IndexSet) { // print("Deleting card at index -> " + indexSet.first) let cardToDelete = self.cards[indexSet.first!] self.managedObjectContext.delete(cardToDelete) do { try self.managedObjectContext.save() } catch { print(error) } reorder() } private func onMove(source: IndexSet, destination: Int) { // pointCards.points.move(fromOffsets: source, toOffset: destination) // source. let firstCard = self.cards[source.first!] //If there is a card located in the destination. if (destination < self.cards.count) { let secondCard = self.cards[destination] let tmp = Int(secondCard.cardOrder) //Increment all place holders from the destination on. for i in tmp..<self.cards.count { self.cards[i].cardOrder += 1 } } firstCard.cardOrder = Int32(destination) do { try self.managedObjectContext.save() } catch { print(error) } self.managedObjectContext.refreshAllObjects() //Reorder just in case moved to the end. reorder() } private func reorder() { for i in 0..<cards.count { cards[i].cardOrder = Int32(i) } do { try self.managedObjectContext.save() } catch { print(error) } } }
Screenshots of my Core Data model using Cloudkit and of the Entitlement selection. Capabilities CoreData Properties UPDATE: I have found the solution. The Persistent Controller should have the following three lines added to the init function: //Setup auto merge of Cloudkit data container.viewContext.automaticallyMergesChangesFromParent = true container.viewContext.mergePolicy = NSMergeByPropertyObjectTrumpMergePolicy //Set the Query generation to .current. for dynamically updating views from Cloudkit try? container.viewContext.setQueryGenerationFrom(.current)
Then this must be ran on real devices. For whatever reason I am unable to get this working in the simulator, but on real devices it syncs in about 30 seconds without closing the app. Thanks everyone for your help!  |
| React-Native - my state being reset after adding values to the current from specific component (panResponder) Posted: 01 Jul 2021 09:20 AM PDT I have a component that I built with useContext. The problem is that my State (named myCartItems) is always being reset and I don't know why. The idea is to add more elements by calling the function addToCart with a product id. then I am trying to copy the current state, and then add the new product to it. But after I check it, I only get the first element every time. I tried to use this without useContext and it worked. For some reason, it doesn't work when I use it with useContext. Here is my component: import React, { useState, useEffect } from 'react' import { StyleSheet, Text, View, Image } from 'react-native' const CartContext = React.createContext(); function CartProvider(props) { const [myCartItems, setCartItems] = useState([]); const addToCart = (product_id) => { let tempArray = [...myCartItems]; const found = tempArray.some(product => product.id === product_id); if (!found) tempArray.push({ id: product_id, count: 1 }); else { for (let i = 0; i < tempArray.length; i++) { if (tempArray[i].id == product_id) { tempArray[i].count = tempArray[i].count + 1; break; } } } setCartItems(tempArray); } return ( <CartContext.Provider value={{ myCartItems, addToCart, resetCart }} > {props.children} </CartContext.Provider> )}
Why do I end up with only one object in the state myCartItems? EDIT: *** I think the problem is the component I send the data from, it looks like when I call the same function from the Homepage - it works perfectly, but when I call it from another component, it happens. import React, { useContext, useEffect, useState, useRef } from 'react'; import { Animated, PanResponder, View } from 'react-native'; import { CartContext } from './provider/CartProvider.js'; export default function DragItem(props) { const context = useContext(CartContext); const pan = useRef(new Animated.ValueXY()).current; const panResponder = useRef( PanResponder.create({ onMoveShouldSetPanResponder: () => true, onPanResponderGrant: () => { pan.setOffset({ x: pan.x._value, y: pan.y._value }); }, onPanResponderMove: Animated.event( [ null, { dx: pan.x, dy: pan.y } ], { useNativeDriver: false, listener: (evt, gestureState) => { } } ), onPanResponderRelease: (evt, gestureState) => { //pan.flattenOffset(); if (gestureState.moveY > 300) { Animated.spring(pan, { toValue: 0, useNativeDriver: false }, ).start(); context.addToCart(props.product_id); } else { Animated.spring(pan, { toValue: 0, useNativeDriver: false }, ).start(); } } }) ).current; return ( <Animated.View style={{ transform: [{ translateY: pan.y }] }} {...panResponder.panHandlers} > {props.children} </Animated.View> ); }
**** EDIT This is the CartContext component (which holds the data) import React, { useState, useEffect, useReducer } from 'react' const CartContext = React.createContext(); function CartProvider(props) { const [myCartItems, setCartItems] = useState([]); const addToCart = (product_id) => { console.log("Added " + product_id + " to cart"); const tempArray = [...myCartItems]; const found = tempArray.some(product => product.id === product_id); if (!found) tempArray.push({ id: product_id, count: 1 }); else { for (let i = 0; i < tempArray.length; i++) { if (tempArray[i].id == product_id) { tempArray[i].count = tempArray[i].count + 1; break; } } } console.log(myCartItems); setCartItems(tempArray); } const resetCart = () => { setCartItems([]); } useEffect(() => { console.log("CartProvider re-rendered with values: "); console.log(myCartItems); }, [myCartItems]) return ( <CartContext.Provider value={{ myCartItems, setCartItems, resetCart, addToCart }} > {props.children} </CartContext.Provider> ) } export { CartProvider, CartContext }
Using the above component, I can't add the values properly to context. Why is that? Github: https://github.com/ornakash/shelf Many thanks  |
| Json case parse problem between Flutter and Net Core WebApi Posted: 01 Jul 2021 09:21 AM PDT I'm having this issue for a while between flutter and dotnet API communication, as the title says, I'm sending a request from flutter app with camelCase objects to dotnet core 3.1 API, but the object is always null, unless I modify my flutter object to PascalCase, which I don't want to. Its working with web, insomnia and others API calls. Literally everything "non-mobile" works. Anyone had this issue? this also happened to me with angular PWA project as well. I tried to forcefully make dotnet parse json as camelcase or without a case at all, and nothing. It seems that if I send/receive from a non-mobile source the API doesn't care the case my object is, but if comes from mobile, it wont work unless its pascal case. it may have nothing to do with casing at all, I'm assuming that's the problem because like I said, if the flutter object is on pascal everything works fine, the object passes through json parsing on the API call and my data is there. But if its not on pascal, object is always null, unless I change my objects inside dotnet to lowercase, again, I don't have to do this on any other web/api project that uses my webapi;  |
