SPARQL query on HM land registry site based on first part of postcode Posted: 08 May 2021 08:22 AM PDT I'm trying to find out average house price data for a postcode area using the HM Land Registry open data SPARQL query via https://landregistry.data.gov.uk/app/qonsole, what the best way to do this if it's for a postcode sector (e.g. GL52)? The 'transactions in a postcode' example code given on there shows how to search a full postcode and I have attempted to alter the code using STRSTARTS() on the VALUES ? postcode section but it's coming back with an error.. prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> prefix owl: <http://www.w3.org/2002/07/owl#> prefix xsd: <http://www.w3.org/2001/XMLSchema#> prefix sr: <http://data.ordnancesurvey.co.uk/ontology/spatialrelations/> prefix ukhpi: <http://landregistry.data.gov.uk/def/ukhpi/> prefix lrppi: <http://landregistry.data.gov.uk/def/ppi/> prefix skos: <http://www.w3.org/2004/02/skos/core#> prefix lrcommon: <http://landregistry.data.gov.uk/def/common/> # Returns the Price Paid data from the default graph for each transaction record having # an address with the given postcode. # The postcode to query is set using SPARQL 1.1's 'values' clause SELECT ?paon ?saon ?street ?town ?county ?postcode ?amount ?date ?category WHERE { VALUES ?postcode STRSTARTS({"GL52"^^xsd:string}, {"GL52"^^xsd:string}) ?addr lrcommon:postcode ?postcode. ?transx lrppi:propertyAddress ?addr ; lrppi:pricePaid ?amount ; lrppi:transactionDate ?date ; lrppi:transactionCategory/skos:prefLabel ?category.

Use diiferent css class when authenticated react Posted: 08 May 2021 08:22 AM PDT I'm kinda new to react I'm wondering how to use another CSS class when I'm authenticated this is my how I tried to solve the problem <section className={store.getState().auth.isAuthenticated ?"container2":"container"}> but the app always use the same style which is "container" this is the full code of App.js import React, {Fragment,useEffect,useState} from 'react'; import './App.css'; import Navbar from './components/layout/Navbar'; import Register from './components/auth/Register'; import Login from './components/auth/Login'; import Landing from './components/layout/Landing'; import {BrowserRouter as Router,Route,Switch} from 'react-router-dom'; import Alert from './components/layout/Alert'; import {loadUser} from './actions/auth'; import setAuthToken from './utils/setAuthToken'; import Dashboard from './components/dashboard/Dashboard'; import PrivateRoute from './components/routing/PrivateRoute'; import CreateProfile from './components/profile-forms/CreateProfile'; import Profiles from './components/profiles/Profiles'; import Profile from './components/profile/Profile'; import Posts from './components/posts/Posts'; import Post from './components/post/Post'; import PostsAdmin from './components/posts/PostsAdmin'; import EditProfile from './components/profile-forms/EditProfile'; import AddExperience from './components/profile-forms/AddExperience'; import AddEducation from './components/profile-forms/AddEducation'; import SideBar from './components/sideBar/SideBar' //Redux import {Provider} from 'react-redux'; import store from './store'; if(localStorage.token){ setAuthToken(localStorage.token); } const App =() => { useEffect(() =>{ store.dispatch(loadUser()); },[]); return ( <Provider store={store}> <Router> <Fragment> <Navbar/> <Route exact path ='/' component={Landing}/> <section className={store.getState().auth.isAuthenticated ?"container2":"container"}> <Alert/> <switch> <Route exact path="/register" component={Register}/> <Route exact path="/login" component={Login}/> <Route exact path='/profiles' component={Profiles}/> <Route exact path='/Posts' component={Posts}/> <Route exact path='/profile/:id' component={Profile}/> <Route exact path='/posts/:id' component={Post}/> <PrivateRoute exact path="/dashboard" component={Dashboard}/> <PrivateRoute exact path="/admin" component={PostsAdmin}/> <PrivateRoute exact path="/create-profile" component={CreateProfile}/> <PrivateRoute exact path="/edit-profile" component={EditProfile}/> <PrivateRoute exact path="/add-experience" component={AddExperience}/> <PrivateRoute exact path="/add-education" component={AddEducation}/> </switch> </section> </Fragment> </Router> </Provider> ); } export default App

CORS Policy problem when I try to connect from Angular to Nodejs backend Posted: 08 May 2021 08:22 AM PDT I´m trying to develop a backend basic server in NodeJS and the front in Angular 11, the fact is when I try to make a http get request to the backend, this is the error message in console: Access to XMLHttpRequest at 'localhost:3000/api/personas' from origin 'http://localhost:4200' has been blocked by CORS policy: Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, chrome-untrusted, https. I´ve tried to config a reverse proxy in angular like this: proxy.conf.json { "/localhost:3000*": { "target": "http://localhost:3000", "secure": false, "logLevel": "debug" } } And the backend is set like this: index.js (nodejs backend) const express = require('express'); const path = require('path'); const methodOverride = require('method-override'); const cors = require('cors'); // Initialitations const app = express(); require('./database'); // Settings app.set('port', process.env.PORT || 3000); // Middlewares app.use(cors({ origin: 'http://localhost:4200' })); app.use(express.urlencoded({ extended: false })); app.use(methodOverride('_method')); // Global variables // Routes app.use('/api', require('./routes/persona')); // Static files app.use(express.static(path.join(__dirname, 'public'))); // Server init app.listen(app.get('port'), () => { console.log('Server on port: ', app.get('port')); })

Create a column name in data frame based on condition with python Posted: 08 May 2021 08:21 AM PDT I have a data frame like this: full path name time 0 C:\Users\User\Desktop\Test1\1.txt 1.txt 10:20 1 C:\Users\User\Desktop\Test1\1.txt 1.txt 10:25 2 C:\Users\User\Desktop\Test1\2.txt 2.txt 10:50 2 C:\Users\User\Desktop\Test1\Test2\1.txt 1.txt 10:30 3 C:\Users\User\Desktop\Test1\1.txt 1.txt 10:40 5 C:\Users\User\Desktop\Test1\Test2\2.txt 2.txt 10:60 and I'm using this code to compare rows (Erfan): m1 = df["full path"].ne(df["full path"].shift(1, fill_value=df["full path"].iloc[0])) m2 = df["name"].eq(df["name"].shift(fill_value=df["name"].iloc[0])) folder = df["full path"].str.rsplit("\\", 2).str[-2] df["time_when_path_changed"] = np.where(m1 & m2, df["time"] + " - " + folder, "") this code gives me this output: full path name time time_when_path_changed 0 C:\Users\User\Desktop\Test1\1.txt 1.txt 10:20 1 C:\Users\User\Desktop\Test1\1.txt 1.txt 10:25 2 C:\Users\User\Desktop\Test1\Test2\1.txt 1.txt 10:30 10:30 - Test2 3 C:\Users\User\Desktop\Test1\1.txt 1.txt 10:40 10:40 - Test1 4 C:\Users\User\Desktop\Test1\2.txt 2.txt 10:50 5 C:\Users\User\Desktop\Test1\Test2\1.txt 2.txt 10:60 10:60 - Test2 What I'm really wanting is to create a column based on the folder path, for example if the path changed to Test2, then to create a column named Test2 and put "time" there, like below: full path name time moved to "Test2" moved to "Test1" 0 C:\Users\User\Desktop\Test1\1.txt 1.txt 10:20 1 C:\Users\User\Desktop\Test1\1.txt 1.txt 10:25 2 C:\Users\User\Desktop\Test1\2.txt 2.txt 10:50 3 C:\Users\User\Desktop\Test1\Test2\1.txt 1.txt 10:30 10:30 5 C:\Users\User\Desktop\Test1\1.txt 1.txt 10:40 10:40 5 C:\Users\User\Desktop\Test1\Test2\2.txt 2.txt 10:60 10:60

Regex match every thing between two outer brackets Posted: 08 May 2021 08:21 AM PDT In a string like this [1 2 [A 4] [5]] how can I match everything in between both outer-brackets (excluding them), e.g. the result would be this match 1 2 [A 4] [5]. Note that I don't want to match the outer-brackets, I a interested only in what comes in between.

Hard time figuring out how to build a 'Service' Model Posted: 08 May 2021 08:21 AM PDT The topic is rather straightforward, but after reading through the docs, examples and some stackoverflow posts I still have not reached a conclusion. Supposed I have two Models, Transaction and Service. The former keeps track of payments made to an entity. Either because someone purchased a product (single-step payment) or because someone purchased a Service (two-step payment, one Transaction payed in advance, another after the service is provided to the user). class Transaction(models.Model): class Provider(models.TextChoices): MBWAY = "MBW", _("MBWay") PAYPAL = "PP", _("PayPal") REVOLUT = "REV", _("Revolut") DEBIT = "DCC", _("Debit or Credit Card") class Status(models.TextChoices): PENDING = "P" PROCESSING = "PR" ACCEPTED = "A" REJECTED = "R" EXPIRED = "E" id = models.BigAutoField(primary_key=True, editable=False) user = models.ForeignKey(User, on_delete=models.SET(User.get_sentinel_user())) provider = models.CharField(max_length=8, choices=Provider.choices) status = models.CharField(max_length=8, choices=Status.choices) value = models.MoneyField(max_digits=19, decimal_places=4, default_currency="EUR") created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) data = models.JSONField(default=dict) class Service(models.Model): id = models.BigAutoField(primary_key=True, editable=False) user = models.ForeignKey(User, on_delete=models.SET(User.get_sentinel_user())) signal = models.ForeignKey( Transaction, unique=true, on_delete=models.PROTECT, related_name="service_signal" ) remainder = models.ForeignKey( Transaction, unique=true, on_delete=models.PROTECT, related_name="service_remainder" ) One Service has exactly two Transaction moments and each Transaction has exactly one Service. Should I use ForeignKey, ForeignKey, Unique or OneToOneField? I understand ForeignKey, Unique and OneToOneField are very similar, but do not understand how different they are other than one returning a QuerySet and another returning an Object when reverse queries are made. Would someone help me figure this out? Would I be better off creating a Purchase model which has OneToOneField to Transaction and Service Model which has a OneToOneField with Purchase and another OneToOneField with Transaction? Thanks in advance.

Qt setText inside a function Posted: 08 May 2021 08:21 AM PDT I want to use setText to overwrite itself inside a loop in a function like this: QString skanner::FSkan(QString fname) { QDir dir = fname; QString abc = 0; QDirIterator iterator(dir.absolutePath(), QDirIterator::Subdirectories); while (iterator.hasNext()) { QFile file(iterator.next()); QFileInfo f; f.fileName(); if ( file.open( QIODevice::ReadOnly ) ){ ui->lineEdit_Output->setText(file.fileName()); This won't work because it is not possible to access ui from MainWindow. How can I make it work?

JavaFX: Populating a TableView from ArrayList without creating a new scene Posted: 08 May 2021 08:21 AM PDT After a few hours of googling, I still have no idea how TableViews work. I have an ArrayList that reads a file and loads some data into it. I need to display the content of that ArrayList in a JavaFX table that I made in SceneBuilder. Everything is in one Scene with one controller because I have no idea how to pass values of variables between controllers (question for another day). I know stuff like logging in etc could be done better, but right now I only need to get tableview working. (and then editing and deleting that... what have I gotten myself into). The method I'm building is populateAnimalTableView(). Help me, StackOverflow, you are my only hope.

Is Firebase SenderID Been Replace With Project Name? Posted: 08 May 2021 08:21 AM PDT I recently began receiving "FirebaseApp with name [SenderID] doesn't exist. Available app names: [appName], [DEFAULT]" when calling Firebase.FirebaseApp.GetInstance(senderID). Changing "senderID" to "appName" enabled the call to be made successfully. I have been using the "senderID" for years. Is this a new change by Firebase? When was it deployed? What happens to app versions that used the former? Fail?

How to combine a surface and quiver plot in python in one plot Posted: 08 May 2021 08:20 AM PDT I have the following code that produces me one surface plot with a surface given as the z-coordinate with respect to a meshgrid X,Y. This code also produces a vector field plot, as a separate figure with respect to the same coordinate system X,Y. Is there a way for me to combine these two figures in one? Have the vector field either on the surface or at the bottom of the surface plot? import numpy as np import matplotlib.pyplot as plt import grad_field # first create the plot of the elevation surface fig, ax = plt.subplots(subplot_kw={"projection": "3d"}) LNG = np.linspace(lngmin,lngmax,samples1) LAT = np.linspace(latmin,latmax, samples2) X, Y = np.meshgrid(LNG,LAT) ax.plot_surface(X, Y, elev_mat) plt.show() # now create the vector field plot of the gradients [gradx,grady] = grad_field.grad_field(elev_mat) fig1, ax1 = plt.subplots() ax1.set_title('Arrows scale with plot width, not view') ax1.quiver(X, Y, gradx, grady, units='xy' ,scale=2, color='red') plt.show()

How can I find the highest occurrence of an item in an array of objects? Posted: 08 May 2021 08:22 AM PDT I have an array of objects and I would like to find the highest occurrence of an item in each object and return the frequency: var arr = [{spot_id: 6, spot_no: 6, gate_id: 6}, {spot_id: 16, spot_no: 17, gate_id: 5}, {spot_id: 5, spot_no: 5, gate_id: 5}, {spot_id: 11, spot_no: 11, gate_id: 5}, {spot_id: 15, spot_no: 16, gate_id: 4}, {spot_id: 4, spot_no: 4, gate_id: 4}, {spot_id: 10, spot_no: 10, gate_id: 4}, {spot_id: 14, spot_no: 15, gate_id: 3}, {spot_id: 9, spot_no: 9, gate_id: 3}, {spot_id: 3, spot_no: 3, gate_id: 3}, {spot_id: 8, spot_no: 8, gate_id: 2}, {spot_id: 13, spot_no: 14, gate_id: 2}, {spot_id: 2, spot_no: 2, gate_id: 2}, {spot_id: 7, spot_no: 7, gate_id: 1}, {spot_id: 12, spot_no: 13, gate_id: 1}]; I have tried to find using this code but it returns an object with values 1, 1, 1 for each field: var items = arr.sort((a, b) => arr.filter(v => v.gate_id === a.gate_id).length - arr.filter(v => v.gate_id === b.gate_id).length ).pop(); I want it to return the highest occurrence of gate_id which in this array is either 5,5,5 or 4,4,4 or 3,3,3 or 2,2,2, basically just one of them, i dont care which one and I want to return the frequency , in this case the frequency is 3 times.

Proguard does not like scala object Posted: 08 May 2021 08:22 AM PDT After running proguard, when i check if methods are available on the obfuscated jar in a new project depending on this last. Desired classes are there but i can't have access to companion object. Library side trait KeepOpen trait KeepOpenObj trait MyTrait extends KeepOpen { def a: Int } object MyTrait extends KeepOpenObj { def apply(arg: Int): MyTrait = new MyTrait { val a = 1 } } Depending project test. import aaa.MyTrait val arg = 1 def myTraitImpl: MyTrait = ??? // Type is well infered def myTraitImpl2: MyTrait = MyTrait(arg) // MyTrait companion object is not detected preventing apply method usage // But this works def myTraitImpl3: MyTrait = (new MyTrait$)(arg) // Works Here are my keep options for classes : "-keep !final class * extends aaa.KeepOpen", "-keep !final class * extends aaa.KeepOpen {*;}", "-keep class * implements aaa.KeepOpenObj", "-keep class * implements aaa.KeepOpenObj {*;}", trait of the library inherit from KeepOpen and object including companion one extends KeepOpenObj. Exploring the jar non obfuscate and obfuscate, they both show two file MyTrait and MyTrait$ with expecting methods but its impossible to use companion object in the obfuscated case. Moreover non companion object like those with main seems to work without any problem. Update I success to make infer companion object type and its associate methods adding following options : -keepattributes Exceptions,InnerClasses,Signature,Deprecated, SourceFile,LineNumberTable,*Annotation*,EnclosingMethod But unfortunately i fall on the following error when compiling. val myTrait = MyTrait(arg) // error : class aaa.MyTrait is not a value How can i have access to the companion object in the same way that with non obfuscate jar ?

Issue with plot in the likert package - superfluous row in image Posted: 08 May 2021 08:21 AM PDT I'm trying to make a likert plot using the 'likert' package by Jason Bryer, with a grouping variable that has 6 levels and two likert scale variables with 5 levels each: plot(likert(likert_krise[,2:3], grouping = likert_krise$krise)) When I run the code, one of the levels of the grouping variables is displayed in two rows: the bars are in the first and the percentage levels in the second.

How to delete a row in csv file in python? [duplicate] Posted: 08 May 2021 08:20 AM PDT I want to delete rows from a csv file as they are processed. My file: 1,Zname1,Zname2,Zname3 2,Yname1,Yname2,Yname3 3,Xname1,Xname2,Xname3 I want to read row by row and delete the row which has been processed. So the file will be now: 2,Yname1,Yname2,Yname3 3,Xname1,Xname2,Xname3 There solutions which are provided on other questions are: read the file use next() or any other way to skip the row and write the remaining rows in an updated file I want to delete the row from the original file which was entered in .reader() method My code: with open("file.txt","r") as file reader=csv.reader(file) for row in reader: #process the row #delete the row I have not been able to figure out how to delete/remove the row I want the change to be in the original "file.txt" because i will be running the program many times and so each time it runs, "file.txt" will already be present and the program will start from where it ended the last time.....

How to display specific user information in a separate page using flask and flask-sqlalchemy? Posted: 08 May 2021 08:20 AM PDT I made only one table in my application. I want to display some information on the page admin.html and specific user information on info.html page. How should I give the query to show the particular user information on which client has clicked on the admin page. I want to display other attributes of my database like email, phone number, college name only on the info.html page. Here are my files: database class database(db.Model): id=db.Column('user_id',db.Integer, primary_key=True) name = db.Column(db.String(20)) text=db.Column(db.String(1000)) personality_score=db.Column(db.Integer) skills_score=db.Column(db.Integer) experience_score=db.Column(db.Integer) total_score=db.Column(db.Integer) college=db.Column(db.String(100)) email=db.Column(db.String(100)) phone_number=db.Column(db.String(100)) app.py @app.route('/admin') def admin(): return render_template('admin.html',database=database.query.order_by(database.total_score.desc()).all()) @app.route('/info') def info(): return render_template('info.html') admin.html <table class="css-serial"> <tbody> <tr> <th>Rank</th> <th>ID</th> <th>Name</th> <th>Profile Summary</th> <th>Personality Score</th> <th>Skills Score</th> <th>Experience Score</th> <th>Total Score</th> </tr><tr> {% for data in database %} <td></td> <td>{{data.id}}</td> <td><a href=info>{{ data.name }}</a></td> <td>{{ data.text }}</td> <td>{{ data.personality_score }}</td> <td>{{data.skills_score}}</td> <td>{{data.experience_score}}</td> <td>{{data.total_score}}</td> </tr></tbody> {% endfor %} </table> I have not written anything in the info.html file because I was not able to figure out how to fetch 'id' or data to display on that page.

I checked it using sql server management studio and it got connected. Please help. I am in a fix. Any help would be appreciated greatly.

Automatically scroll multiline TextFormField when it extends the maxLines attribute Posted: 08 May 2021 08:22 AM PDT I'm implementing a TextFormField with the maxLines attribute set to 3. How can I make the TextFormField scroll down once the user starts with his fourth line? At the moment the cursor is just not visible anymore until the user scrolls down by hand. Is there a way to do this automatically? This behaviour is actually featured in the flutter_gallery app in the 'Text fields' example. Just type a long text to the 'Live story' input until it reaches the fourth line. The important parts of my code actually look like this: import 'package:flutter/material.dart'; class TextFormFieldDemo extends StatelessWidget { @override Widget build(BuildContext context) { return new Scaffold( body: new Form( child: new TextFormField( maxLines: 3, ), ), ); } } So far I have found no workaround for this issue. This issue affects both iOS and android.

Fetch: POST JSON data Posted: 08 May 2021 08:20 AM PDT I'm trying to POST a JSON object using fetch. From what I can understand, I need to attach a stringified object to the body of the request, e.g.: fetch("/echo/json/", { headers: { 'Accept': 'application/json', 'Content-Type': 'application/json' }, method: "POST", body: JSON.stringify({a: 1, b: 2}) }) .then(function(res){ console.log(res) }) .catch(function(res){ console.log(res) }) When using jsfiddle's JSON echo I'd expect to see the object I've sent ({a: 1, b: 2}) back, but this does not happen - chrome devtools doesn't even show the JSON as part of the request, which means that it's not being sent.
