Is there any possible way to implement a drag and drop html editor in the django admin panel
I have a website and there will be some people who I'll give the admin login credentials to but they don't know anything about html, css... I want it so that within the page they could edit it like if it was wordpress. I searched up for it and found something similar named django-cms. Is there any possible way to use a drag-and-drop html editor within the page? Notes: Website is built with django, python3.9 and hosted on heroku. -

Defining a custom Serializer Field for related models gives TypeError
My question is similar to this unanswered question. I'm trying to implement a serializer field to my project. I'm hitting a roadblock where I need to nest other models in a single request, but it throws a TypeError: Object of type ____ is not serializable. Here's what my models.py code's pseudocode looks like: (GameIndexPage has many GameBlogPage has one Game) (I omitted things I think is irrelevant) @register_snippet class Game(models.Model): title = models.CharField(max_length=150) def __str__(self): return self.title class GameBlogPage(Page): parent_page_type = ['blog.GameIndexPage'] introduction = models.TextField game = models.ForeignKey 'web_api.Game' album_image = models.ForeignKey 'wagtailimages.Image' body = StreamField([ ('heading', blocks.CharBlock(form_classname="full title")), ('paragraph', blocks.RichTextBlock()), ('image', ImageChooserBlock()), ]) published_date = models.DateTimeField() class GameIndexPage(Page): subpage_types = ['GameBlogPage'] parent_page_type = ['home.HomePage'] introduction = RichTextField image = models.ForeignKey 'wagtailimages.Image' @property def children(self): return self.get_children().specific().public().live() ... api_fields = [ APIField('introduction'), APIField('image'), APIField('children', serializer=GameBlogPageField()) ] Now, here's my implementation of the serializer field in fields.py: class GameBlogPageField(Field): def to_representation(self, queryset): pages = [] for child in queryset: post_dict = { "id": child.id, "title": child.title, "introduction": child.introduction, "game": child.game # where it all goes wrong #"blog_authors": child.blog_authors, #"published_date": child.published_date, #"album_image": child.album_image, } pages.append(post_dict) return pages Removing the game value gives me this result.

Failed conversion to JSON for JsonField

How do I get Django PK value in a CBV whithout appearing in the URL?
I basically want the PK of the user who has logged in to my website. I don't want it to appear in the URL so I cannot use kwargs.

Django CountrySelectWidget not working when Debug=False
I am using Django Countries and the CountrySelectWidget to show the country flag after the CountryField on my form. This works fine when Debug is set to True and I can see the flag fine. However when Debug is set to False the flag image shows as broken. I have set my static files and media files to be collected and served when DEBUG is False but I don't think that the CountrySelectWidget involves static files. Django Countries is installed on my Django environment and the CountryField is working fine both when Debug is True and when it is False. So I don't know why the Widget doesn't seem to be working properly when Debug is False. My forms.py is as follows: from django import forms from django_countries.widgets import CountrySelectWidget from catalog.models import emaillist class Subscribe(forms.ModelForm): class Meta: model = emaillist fields = "__all__" widgets = {'country': CountrySelectWidget()} And my model is: class EmailList(models.Model): email = models.EmailField() country = CountryField(blank_label='(select country)', default = 'South Africa') def get_absolute_url(self): # new return reverse('download-file') I'm using Django 3.1.7 If you can help me I would be very grateful!

Connecting BigQuery to Django and React
I love working with Django as my backend and React as my frontend and I think they make an amazing combination. However, I would like to use BigQuery as my database and I'm having a hard time on thinking about how should i go about building the system flow. What I would like to do is to read data from BigQuery and display on my frontend (React) and also would love to insert data into my BigQuery database through a form in React, which then could be somehow processed in Django and inserted into the BigQuery. I know this should be possible by creating a REST API using Django Rest Framework but I'm currently lost and I could not find any article or video guidance anywhere on the internet. Any reference or help would be highly appreciated. Thank you! -

Better alternative to polling when waiting for a HTTP request in django?
I have a django application that needs to communicate with a backend service. Usually I would do it like this: def my_view(request, id): backend_response = requests.get('http://backend.com/{}/'.format(id)) return HttpResponse(status=backend_response.status_code) Unfortunately the backend service in this case does not work like that. Instead of including the results in the HTTP response it will send them in a separate HTTP request. My current approach is to write the results to the database and wait for them in the original request handler: def my_view(request, id): requests.get('http://backend.com/{}/'.format(id)) while True: sleep(1) try: backend_response = BackendResponse.objects.get(id=id) break except BackendResponse.DoesNotExist: pass return HttpResponse(status=backend_response.status_code) This feels very weird to me. Are there better solutions for this problem? -

How to only fetch the ArticleImage items that match the author id of Article?
So lets say that User with id "1" created an Article, but User only wants to show the article images in ArticleSerializer that match with the User id "author" of ArticleImage.

Supplying remote JSON data for Typeahead / Bloodhound with Django / Python
I'm trying to replicate functionality of this Typeahead remote example, but I can't figure out how to supply the data in the way Typeahead / Bloodhound wants it, nor what datumTokenizer or queryTokenizer are for. In Python / Django views.py I've got: nouns = ['apple', 'banana', 'pear'] return JsonResponse({'results': noun_results}) reaching the site as: {"results": ["apple", "banana", "pear"]} Yet for 'kings' the example returns: [{"year": "1949","value":"All the Kings Men","tokens":["All","the","Kings","Men"]}] Need we return it in this format? If so, how? How can we make a simple replication of the example?
