Responsive design combined with Bootstrap and Django doesn't work
I do not know where I make errors. What is not correct in my code? I have website with subpages as below. Responsive design doesn't works. Is it related to any mistake in HTML/CSS code or instead of media queries I should use any specific way of making responsive design in bootstrap? Generally there is a problem with rows and columns - I can't change margins and font size responsively. Might it be related to django inheritance mechanism? {% load static %} <!DOCTYPE html> <html> <head> <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/css/bootstrap.min.css" integrity="sha384-Vkoo8x4CGsO3+Hhxv8T/Q5PaXtkKtu6ug5TOeN$ <script src="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/js/bootstrap.min.js" integrity="sha384-wfSDF2E50Y2D1uUdj0O3uMBJnjuUD4Ih7YwaYd1iqfktj0Uod8GCExl3$ <link rel="stylesheet" type="text/css" href=relax/css/grid.css"> <title>Visyrelax</title> <meta name="viewport" content="width=device-width, initial-scale=1"> <style> body { background: #F8F8FF; } /* Adding !important forces the browser to overwrite the default style applied by Bootstrap */ .row{ margin:100px; } @media (min-width: 576px) { @include media-breakpoint-up(sm) .row{ font-size:10px; margin:10px; } } @media (min-width: 768px){ @include media-breakpoint-up(sm) .row{ font-size:20px; margin:10%; } } @media (min-width: 1200px){ @include media-breakpoint-up(sm) .row{font-size:60px;} p{ font-size:25px; } } </style> </head> <body> <nav class="navbar navbar-dark bg-dark"> <a class="navbar-brand" href ="{% url 'index'%}"> <p style="font-size:40px;"> &nbsp;&nbsp; <font color=DodgerBlue> Visy</font><font color$ <div class="navbar"> <a class= "nav-item nav-link" href ="{% url ‘a’%}”><font color=white>a</font></a> <a class= "nav-item nav-link" href ="{% url ‘b’%}”><font color=white>b</font></a> <a class= "nav-item … -
A way to check coverage of API tests for Django applications with Pytest
I have an application based on Django framework. Under the repo of the Django app, there is a repo which contains API tests based on Pytest framework. I am using requests library to send a request to the server, and asserting on the response data. An example of API test: import requests def test_some_api(self): s = requests.Session() response = s.get('/api/some_api') assert response.status_code == 200 Is there any way to know how many lines of code ran out of total amount of code lines of a given module? I managed to get a nice report with pytest-cov, but it works only for Unittests (calling functions directly from server repo). -
How to refresh 'refresh token' in django
Whenever I get a new access token using Refresh token, I want to get it reissued as well. So after coding as I thought, the refresh token was the same as the one issued before.

Django not serving HTML table in template (word counter web app)
Summary: Django is not rendering a basic 2 column by 11 row HTML table containing the top 10 most commonly used words in a large text file (Alice and Wonderland which is a public domain work). But right now the table is empty. Details: The table currently rendering on the web page looks like this, see here on imgur. In that pic, notice the bottom right corner, the table is empty. The fully populated word counter table and its contents rendering when a web user navigates to http://127.0.0.1:8000/counters. See here on imgur. However the problem there is that then the blog post lorem ipsum content is empty. See here: Here is my parent top level urls.py: from django.contrib import admin from django.urls import path, include from django.conf import settings from django.conf.urls.static import static urlpatterns = [ path('admin/', admin.site.urls), # path('', include('mortems.urls')), path('', include('redactors.urls')), path('', include('posts.urls')), path('', include('counters.urls')), ] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) Here is my counters app’s views.py: from django.shortcuts import render from collections import Counter import re from nltk.corpus import stopwords def counters(request, text=""): """ This function processes the top 10 most common words in a text file and then renders them.

Javascript how to know the current user? Session variable dont work? Uncaught (in promise) ReferenceError: require is not defined
SO this is my js code document.addEventListener('DOMContentLoaded', function() { document.querySelector('#inbox-view').innerHTML = `<p class="header" >Messages</p> `; fetch('/inbox') .then(response => response.json()) .then(messages => { messages.forEach(message => { let msection = document.createElement("div"); //create a clickable area let content = `<a href="#" class="posta"><img src="${message.senderimage}" class="rounded-circle"> <h4> ${message.sendername}</h4> <p style="display:inline;"> @${message.sender}</p> <p class="posta" id="myMessage"> ${message.content}</p> </a> <br> <br> <hr>`; msection.innerHTML = content; //set its content msection.setAttribute('class','msec'); //set its style msection.href ="#"; // make it clickable var session = require('express-session') if(`${message.sender}` != session){ document.querySelector('#inbox-view').append(msection); } What I want is I have this dynamic content in a Django Project. I want to display only the messages didn't send by the current user( basically display an inbox, not reply messages) In this section of my code var session = require('express-session') if(`${message.sender}` != session){ document.querySelector('#inbox-view').append(msection); } I want to check if the sender is current user if so I don't want to display that message. I already install thee package npm install express-session but still gives me this error: Uncaught (in promise) ReferenceError: require is not defined at inbox:130 (Without this session thing code works just fine) So what is the way of knowing the logged-in user? Is there any other way? Thank you -

how to get list of active celery tasks inside django views

Django Rest Framework - Serializing optional OneToOne relation
Suppose I have a Rating model used to store ratings on specific categories. Users can either provide a generic rating on a specific category, or they can provide a rating on a specific category guided by a question they were asked. The question thus is an optional field. Please note that this is a simplified example. In reality I am dealing with multiple optional fields. Therefore I would like to avoid using null for optional fields. To accomplish this I have created the following two models: class Rating(models.Model): score = models.IntegerField() category = models.CharField() class QuestionRating(models.Model): rating = models.OneToOneField(Rating, primary_key=True) question = models.CharField() These models model a missing question by a missing row instead of a null value which, as far as I know, is best practice. I would like to expose these models through a single API endpoint with a Django REST Framework ViewSet. On serialization the serializer should add a 'question' field only if a QuestionRating exists, and on deserializiation it should create/update the QuestionRating only if a 'question' field is provided; What would be the best way to accomplish this with a DRF serializer? -

Is there a way to serialize multiple objects in Django?
In a Django Project I would like to implement a simple chat-box.

Django Python - Variable seems to be getting cached?
Within my Django app I obtain a list of projects within our Google Cloud Organisation with the following: try: global projectdicts projectdicts = cloudresmanv1.projects().list().execute() projectdicts = projectdicts.get('projects') except Exception as e: logging.error(e) The above is taken from a Django form called ProjectForm. However, after I've created a GCP project and browse within my Django app to the ProjectForm page again, the list doesn't update to show the newly-created project. My understanding is that it should run the above again, regardless. If I run through the script manually, the projectdicts variable of course updates. So, this leads me to believe for some reason the Django app or Python is caching the variable and not bothering to run the above again. Is this a likely problem? And if so, how do I force Django/Python to re-run this part of the script again to ensure the list of GCP projects is updated whenever I browse to the ProjectForm page? -
