| How can I click this button using selenium? Posted: 12 Sep 2021 08:43 AM PDT <button name="main" type="submit" class="mainfont"> التسجيل</button>
XPath: /html/body/table/tbody/tr[2]/td/table/tbody/tr/td/table[1]/tbody/tr/td[18]/font/button Full XPath: /html/body/table/tbody/tr[2]/td/table/tbody/tr/td/table[1]/tbody/tr/td[18]/font/button How can I click this button in selenium? I have tried different methods but none worked, some notes: - There are different submit buttons called "main" with mainfont class
- I tried using the XPath but the function also requires me to use the text inside the button, which is in arabic characters that split into two lines in python text editor, which ofcourse does not work as it needs to be in 1 line, but if I erase the space and make it into one code line, it won't work (probably because it is written in two lines in the HTML code?)

| Kubernetes - Use flyway job to perform migrations on postgres database - Connection problems Posted: 12 Sep 2021 08:43 AM PDT The problem Error photo Flyway Job Error I'm currently attempting to use flyway to perform migrations in postgres. I have a feeling the init scripts are unable to be found based on this error message. Not too sure what I'm missing as the init scripts worked when using docker containers. Any help would be appreciated for solving this issue. What I have tried: - So far I have tried playing with the connection string inside the job to see if it was a connection problem.
- Then I tried using a config map with the init sql script inside to hopefully have the script visible for migrations. Didn't have too much luck with that approach. I have attached the example that I found for this approach. Migrations with ConfigMap for init sql scripts
I have some more research links that I found but they didn't quite fit or work with my problem and weren't as noteworthy or were outdated. - Database migrations in Kubernetes with flyway video
- Continuous Database configuration with flyway
Code/Kubernetes setup What follows is my current setup: Side note: I am using kind to pull my docker images locally and create my clusters, I will attach my docker compose and docker files at the end. Flyway Setup I have Flyway as a Job in Kubernetes with this structure: Flyway job file apiVersion: batch/v1 kind: Job metadata: name: flyway-migration-job spec: template: spec: containers: - name: flyway image: flyway/flyway:6.3.1 command: ["flyway -url=jdbc:postgresql://postgres-master:5432/wallet -user=test_user -password=testuser1234 -connectRetries=60 migrate"] restartPolicy: Never backoffLimit: 1

Postgres service file I have then exposed the Postgres pod using this Postgres service: apiVersion: v1 kind: Service metadata: name: postgres-master labels: app: postgres-master spec: type: NodePort ports: - protocol: TCP port: 5432 targetPort: 5432 selector: app: postgres-master
Node setup I also have a node deployment which connects to the database pod and I have confirmed that I have been able to connect to the database using hostname postgres-master(pod name), the above login details and port 5432. Node deployment file I've attached the node deployment file for completeness but it works. apiVersion: apps/v1 kind: Deployment metadata: name: node-deployment labels: app: node-deployment spec: replicas: 3 selector: matchLabels: app: node-deployment template: metadata: labels: app: node-deployment spec: containers: - name: node image: wallet-api-20_web:latest imagePullPolicy: IfNotPresent ports: - containerPort: 8080 env: - name: PG_HOST value: "postgres-master.default"
Docker setup Docker compose Then I have my docker compose file which I use to build my images: Side not - All of the docker images worked together including migrations before I started adding Kubernetes. version: '3.5' services: web: build: dockerfile: ./Dockerfile container_name: wallet-api-web depends_on: - flyway ports: - "8080:8080" postgres-db: build: dockerfile: ./utils/db.Dockerfile container_name: postgres-db environment: POSTGRES_PASSWORD: testuser1234 POSTGRES_USER: test_user POSTGRES_DB: wallet image: postgres:12 ports: - "5432:5432" restart: always flyway: command: -url=jdbc:postgresql://db:5432/wallet -user=test_user -password=testuser1234 -connectRetries=60 migrate container_name: flyway-migrations depends_on: - db image: flyway/flyway:6.3.1 volumes: - ${PWD}/migrations/sql:/flyway/sql

Any help would be appreciated, I have a feeling this might be something small I am missing. If anymore information is required please let me know. Feel free to add any questions as well and I will do my best to provide further context. Thank you.  |
| Centre bars in barplots if category is missing in hue Posted: 12 Sep 2021 08:42 AM PDT If one uses hue in seaborn's barplot and one of the categories is missing, it leads to this strange effect of "empty columns" where seaborn plots nothing at the place where it expects the hue to be (see below at the second position, Fri; or in the second picture). How can one centre such cases so that it is at the place of the tick? In the first case, it would be in the middle of the orange bar, in the second it would remove the empty space between the blue and green and place the tick in the middle of the green bar. Thanks. import seaborn tips = sns.load_dataset("tips") tips.loc[(tips["sex"]=="Male")&(tips["day"]=="Fri"), "total_bill"]=np.nan sns.barplot(x="day", y="total_bill", hue="sex", data=tips) sns.barplot(x="sex", y="total_bill", hue="day", data=tips)
Side note, it is unrelated to this post.  |

| React Typescript Error: Invariant failed: You should not use <withRouter(App) /> outside a <Router> Posted: 12 Sep 2021 08:41 AM PDT I was developing an App where I use Firebase as an Authentication system of the App, an when I try to implement the routes of the app, I start to get the above title error. I'm using withRouter funtion, to encapsulate my App component.

`So I think that have to be realated with the configuration of Route library into the main component of the app. What I missing?? Take thankss in advance !  |

| Component not updating after fireEvent.click Posted: 12 Sep 2021 08:41 AM PDT I'm new with Jest and testing-library. I have a NavbarContainer component that renders one button or another depending of a variable (menuOpen) that it's being changed with a function. I have already checked that the variable changes its value after the fireEvent, however, it seems as the component it's not updating. What am I doing wrong? Here there is my component export const NavbarContainer = ({functionality, menuOpen, activeLink}) => { return ( <div className="navbar-container"> { menuOpen && <Navbar functionality={functionality} activeLink={activeLink}/> } { menuOpen && <Button text="navbar.back" functionality={functionality}></Button> } { !menuOpen && <Button text="navbar.menu" functionality={functionality} modificator="back"></Button> } </div> ); };
Here are the values and functions I am passing to NavbarContainer component const [menuOpen, setMenuOpen] = useState(false); const [activeLink, setActiveLink] = useState(""); const openMenu = (link) => { setMenuOpen(!menuOpen); setActiveLink(link.toString()); };
Here are my tests describe("NavbarContainer", () => { i18n.changeLanguage('cimode'); let component; let menuOpen = true; const openMenu = () => { menuOpen = !menuOpen; }; beforeEach(() => { component = render( <BrowserRouter basename="/"> <NavbarContainer menuOpen={menuOpen} functionality={openMenu} activeLink=""/> </BrowserRouter> ); }); it("after click the menu button is shown", async () => { const backButton = component.queryByText("navbar.back"); await fireEvent.click(backButton); const menuButton = await component.queryByText("navbar.menu"); expect(menuButton).toBeInTheDocument(); }); });

| If a file was found more than once in subfolders - delete all using batch script Posted: 12 Sep 2021 08:43 AM PDT The system I'm working on looks like this: D:\TargetFolder\Subfolder1 D:\TargetFolder\Subfolder2\Subfolder3
There is a file called "Settings.txt" that could exist in each of these folders. what I want is the following: If the file was found more than once in the targeted folder and all of its subfolders then delete all of them. If the file was found just once in the targeted folder and all of its subfolders then continue on with the script. If the file doesn't exist then continue on with the script. The final script could possibly be something like this: IF exist "D:\TargetFolder\*Settings.txt" (goto delete) else goto continue :delete del *Settings.txt /f /q :continue exit
I hope, I explained my question correctly. Thanks in advance.  |

| Merge two txt files as columns in Windows Posted: 12 Sep 2021 08:42 AM PDT I need to be able to merge as separate columns files with millions of lines. I tried using the suggested code here: @echo off set f1=1.txt set f2=2.txt set outfile=mix.txt type nul>%outfile% ( for /f "delims=" %%a in (%f1%) do ( setlocal enabledelayedexpansion set /p line= echo(%%a!line!>>%outfile% endlocal ) )<%f2% pause
Concatenate 2 txt files line by line using Batch But when I run it with non-ASCII (Greek) text I get a weird output and the encoding in result file changes from UTF-8 to Windows-1253 with corrupt Greek characters (despite all files involved, including the batch file, being UTF-8). Also, I get no separator (I want it to be tab). Example input file1 Agenda
file2 Διάταξη των εργασιών
Output AgendaΞ"ιάταξη των ΞµΟΞ³Ξ±ΟƒΞΉΟŽΞ½
Desired Output Agenda[TAB]Διάταξη των εργασιών

| Is there a formula in google sheets where it picks one option out of many to assign to a cell? Posted: 12 Sep 2021 08:42 AM PDT I have a column full of models of cars, a column next to it that assigns the correct car type (hatchback, pick up, etc) to the car model. In the third column, I have more than 1000 car models which need to have these car types associated with them. Is there a formula that can help me do this? I tried nested Ifs but there are around 45 car models so this is a bit inefficient I thought.  |
| How do I display the numbers 0 to 10 in react native without repetition each time I click on the output? Posted: 12 Sep 2021 08:42 AM PDT I want the numbers 0 to 10 to be repeated only once and then start counting from 0 to 10 again. enter image description here import React, {Component} from 'react'; import { StyleSheet, Text, View, StatusBar, SafeAreaView, TouchableOpacity, } from 'react-native'; import Ionicons from 'react-native-vector-icons/Ionicons'; export class CertificationScreen extends Component{ constructor(props) { super(props); } render() { const count = 0; return ( <SafeAreaView style={styles.container}> <StatusBar barStyle="light-content" /> <View style={styles.item}> <TouchableOpacity onPress={() => this.props.navigation.navigate('Forms', {itemId: count + 1 })}> <Ionicons style={styles.icons} name="arrow-back" size={24} color="#0064FE" /> <Text style={{fontSize: 24}}>Text</Text> </TouchableOpacity> </View> </SafeAreaView> );} }
I researched a lot, but I could not solve this problem. please guide me. Yes, this is exactly what I want, to add a number by tapping TouchableOpacity. And send this data to my class component via props (itemId). But after making changes, I get this error: Too many re-renders. React limits the number of renders to prevent an infinite loop. Do you know a better way I can use it? import React from 'react'; import { StyleSheet, Text, View, StatusBar, SafeAreaView, TouchableOpacity, } from 'react-native'; import Ionicons from 'react-native-vector-icons/Ionicons'; export function CertificationScreen() { let [counter, setCounter] = React.useState(); if (counter < 10) { setCounter(counter += 1); } else { setCounter(0); } return ( <SafeAreaView style={styles.container}> <StatusBar barStyle="light-content" /> <View style={styles.item}> <TouchableOpacity onPress={() => this.props.navigation.navigate('Forms', {itemId: setCounter })}> <Ionicons style={styles.icons} name="arrow-back" size={24} color="#0064FE" /> <Text style={{fontSize: 24}}>Text</Text> </TouchableOpacity> </View> </SafeAreaView> ); }

| Count nodes within k distance of marked nodes in grid Posted: 12 Sep 2021 08:42 AM PDT I am attempting to solve a coding challenge however my solution is not very performant, I'm looking for advice or suggestions on how I can improve my algorithm. The puzzle is as follows: You are given a grid of cells that represents an orchard, each cell can be either an empty spot (0) or a fruit tree (1). A farmer wishes to know how many empty spots there are within the orchard that are within k distance from all fruit trees. Distance is counted using taxicab geometry, for example: k = 1 [1, 0] [0, 0] the answer is 2 as only the bottom right spot is >k distance from all trees.
My solution goes something like this: - loop over grid and store all tree positions
- BFS from the first tree position and store all empty spots until we reach a neighbour that is beyond k distance
- BFS from the next tree position and store the intersection of empty spots
- Repeat step 3 until we have iterated over all tree positions
- Return the number of empty spots remaining after all intersections
I have found that for large grids with large values of k, my algorithm becomes very slow as I end up checking every spot in the grid multiple times. After doing some research, I found some solutions for similar problems that suggest taking the two most extreme target nodes and then only comparing distance to them: However this does not work for my challenge given certain inputs like below: k = 4 [0, 0, 0, 1] [0, 1, 0, 0] [0, 0, 0, 0] [1, 0, 0, 0] [0, 0, 0, 0]
Using the extreme nodes approach, the bottom right empty spot is counted even though it is 5 distance away from the middle tree. Could anyone point me towards a more efficient approach? I am still very new to these types of problems so I am finding it hard to see the next step I should take.  |
