How to separate lines in django text_Field model?
I have written the following code in my models.py file: from django.db import models from django.utils import timezone from django.contrib.auth.models import User from django.urls import reverse # Create your models here. class Post(models.Model): title = models.CharField(max_length=200) content = models.TextField() date_posted = models.DateTimeField(default=timezone.now) author = models.ForeignKey(User, on_delete=models.CASCADE) genere = models.CharField(max_length=50, default='') def __str__(self): return f'{self.title} by {self.author}' In my views.py file I have written: from django.shortcuts import render from .models import Post from django.views.generic import ListView class PostListView(ListView): model = Post template_name = "blog/index.html" context_object_name = "posts" ordering = ["-date_posted"] In my index.html I have written: {% extends "blog/base.html" %} {% load static %} {% block content %} {% for post in posts %} <article class="col-12 col-md-6 tm-post"> <hr class="tm-hr-primary"> <a href="{% url 'blog-detail' post.id %}" class="effect-lily tm-post-link tm-pt-60"> <div class="tm-post-link-inner"> <img src="{% static 'img/img-01.jpg' %}" alt="Image" class="img-fluid"> </div> <span class="position-absolute tm-new-badge">New</span> <h2 class="tm-pt-30 tm-color-primary tm-post-title">{{ post.title }}</h2> </a> <p class="tm-pt-30"> {{ post.content|safe|truncatewords:"30"|linebreaks }} </p> <div class="d-flex justify-content-between tm-pt-45"> <span class="tm-color-primary">{{ post.genere }}</span> <span class="tm-color-primary">{{ post.date_posted|date:'N j,Y' }}</span> </div> <hr> <div class="d-flex justify-content-between"> <span>36 comments</span> <span>by {{ post.author }}</span> </div> </article> {% endfor %} {% endblock %} Suppose if I add the following things in my post.content: laborum deserunt do excepteur … -

best way to create example project in a django plugin test suite
This may be a simple question, but I can't wrap my head around it. Given I make a Django plugin app, lets name it foo, which adds some database features, that other apps can use (e.g. models that must be inherited), and I want to add tests for that app. Structure: foo/ apps.py models.py tests/ test_foo_basic.py test_bar.py ... setup.py README.md ... The project is no full Django application, as it is an plugin app for others. So I need to create a fake Django project within the testing directory, with at least one app, which defines some models that inherit from foo.models.<some_model> and test it, right? Is that the only way? It seems a but much for me. If so, it's ok for me to give me the answer "it is so". And I'll accept ;-) If not, please tell me I am complicated and show me something easier, a pytest plugin etc.? For testing, I need a -

DRF & Next.js: Cookies are not stored in the browser only in the production environment
I'm working on a web app with DRF in the back and Next.js in the front. For some reason, only in the production environment, the JWT cookie from authentication is not saved in the browser. For DRF authentication, we use dj-rest-auth and djangorestframework-simplejwt. We are using axios to fetch from Next.js and have withCredentials: true enabled. Everything works fine in the local environment, but why aren't cookies being saved in the production environment?

How to format negative numbers in django-tables2?
I am looking for nice solution to make a simple subclassed NumericColumn for my tables, based on django-tables2. I started with that: class NumericColumn(Column): def render(self, value): return '{:0,.2f}'.format(value) It works great until I decided to make negative values red: class NumericColumn(Column): attrs = { 'td': { 'class': lambda value: 'text-danger' if value < 0 else '' } } def render(self, value): return '{:0,.2f}'.format(value) Code periodically fails with TypeError: '<' not supported between instances of 'str' and 'int', and it seems that lambda function receives already formatted value. I don't see a way to get an original value in record via accessor, and I don't think that it is nice to make a reverse conversion to Decimal for such comparison. Ok, I can test first character for '-', but it is too ugly. Please help. -

How to get all fields of related object Django
I have two models: class Checklist(models.Model): author = models.ForeignKey(User, null=True, on_delete=models.SET_NULL) client_name = models.ForeignKey(Client, on_delete=models.CASCADE, related_name='details') filedA = models.CharField(max_length=25, blank=True, null=True) filedA_Check= models.BooleanField(default=False) filedB = models.CharField(max_length=25, blank=True, null=True) filedB_Check= models.BooleanField(default=False) class Client(models.Model): client_filedA = models.CharField(max_length=25) client_filedB = models.CharField(max_length=25) client_filedC = models.CharField(max_length=25) Now I trying to change Client instance fields values via Checklist using following code: @login_required def create_order(request, pk): instance = get_object_or_404(CheckList, id=pk) form = myForm(request.POST or None, instance=instance) if form.is_valid(): form.save() messages.success(request, 'Test message') return get_PDF_order(request, pk) return render(request, 'templates/create_order.html', {'form': form}) And it's works but only once. Data saved and I get a pdf file with this data, but subsequent attempts do not change anything. The field value still the same. I'm guessing that it is because I working with the Checklist instance but not Client. So, my questions are: 1) How I can get an access to all Client fields (a queryset of all fileds) via Checklist? 2) Although my code is incorrect - why does it work (once)? I mean why does it save first time? Thank you all in advance! -

Display only certain events in iframe
I am currently using a Service account that displays all the events for all days using the Google api calendar. I would like to display only events for a user within the embed iframe or create an own table. Now I have been looking into OAuth 2.0 Client IDs and tokens as well. Is there a way to create different calendars based of each user and then get their iframe as well(similar idea different execution though as iframe locations would be problematic). The calendars should be permanent unless the user is deleted. Would a generic table creation be more useful here? and how would I go about creating one. iframe: {% block content %} <h1>Calendar</h1> <button> + </button> <iframe src="https://calendar.google.com/calendar/embed?src=------" style="border: 0" width="800" height="600" frameborder="0" scrolling="no"> </iframe> <ul> {% for result in results %} <li>{{result.start.date}}{% if result.end.date %}-{% endif%}{{result.end.date}}: {{result.summary}}</li> {% endfor %} </ul> {% endblock %} for service from decouple import config from google.oauth2 import service_account import googleapiclient.discovery import datetime CAL_ID = config('CAL_ID') SCOPES = ['https://www.googleapis.com/auth/calendar'] SERVICE_ACCOUNT_FILE = './google-credentials.json' def test_calendar(): print("RUNNING TEST_CALENDAR()") credentials = service_account.Credentials.from_service_account_file(SERVICE_ACCOUNT_FILE, scopes=SCOPES) service = googleapiclient.discovery.build('calendar', 'v3', credentials=credentials) """ new_event = { 'summary': "Ben Hammond Tech's Super Awesome Event", 'location': 'Denver, CO USA', 'description': 'https://benhammond.tech', … -
