Django allauth SocialAccount model's "extra_data" field
SocialAccount model has the extra_data field in the table. And this model has a relation with the User table. when I am retrieving the User table, trying to add the SocialAccount into the User but having an error. serializers.py from rest_framework import serializers from django.contrib.auth.models import User from allauth.socialaccount.models import SocialAccount class SocialAccountExtraDataSerializer(serializers.ModelSerializer): class Meta: model = SocialAccount fields = ["extra_data"] depth = 1 class UserDisplaySerializer(serializers.ModelSerializer): extra_data = SocialAccountExtraDataSerializer() class Meta: model = User fields = ["username", "extra_data"] depth = 1 the error message says: Got AttributeError when attempting to get a value for field extra_data on serializer UserDisplaySerializer. The serializer field might be named incorrectly and not match any attribute or key on the User instance. Original exception text was: 'User' object has no attribute 'extra_data'. How should I insert the SocialAccount's extra_data into User serializer as field. incase if you need to see views.py from rest_framework.response import Response from rest_framework.views import APIView from users.routes.serializers import UserDisplaySerializer class UserDisplayApiView(APIView): def get(self, request): serializer = UserDisplaySerializer(request.user) return Response(serializer.data) -

Multiple root pages in Wagtail
I currently use wagtail as a blog which is accessible via example.com/blog and the admin via example.com/blog/admin. I would like to also use wagtail to create a support (knowledge base) section. This would then be accessible via example.com/support. The pages and models for the blog vs support section would be different since they're catering to different use cases. Would something like the following be possible? example.com/wagtail - wagtail admin (for both the blog and knowledge base) example.com/blog - blog section of the site example.com/support - knowledge base / support section of the site If the above is not possible I would also be open to having two completely separate wagtail apps in my django project, eg: example.com/blog - this is a blog wagtail section with its own admin example.com/blog/admin example.com/support - this is a separate support wagtail section with its own admin example.com/support/admin I'm not entirely sure which option is possible or how to go about getting either one to work. -
Integrate Dataframe from a Python File to Django
I've developed a complex data analysis model using Python (for the sake of simplicity, let's call it analysis.py) which contains multiple long algorithms to transform a set of raw data and spits out output in the form of dataframe as well. I've been looking into some tutorials recently on Django framework and have tried building a simple web app that resembles a forum/blog post web app. With the dataframe output from the analysis.py, I would like to display the data in the form of multiple charts on the web app. Can anyone point me to a direction to move from here? I've looked for multiple resources online but I think I am unable to find the correct keywords that match with what I actually want to build. I just want a shell code kind of a thing to integrate into my current django backend in order to be able to call the dataframe from the analysis.py Thank you very much in advance. -

How to put checkboxes side by side Django Form
I'm using Django and I need to present a ModelForm with some checkboxes in my template. The problem is that the checkboxes are in a vertical line, one after another. I need them to be evenly distributed in my page, for example 3 columns containing 4 checkboxes each. At the moment I only have 1 column with all my checkboxes inside it. This creates a scroll and the page looks awful. I've tried adding CSS classes and IDs as widgets in my "forms.py" file, I can change some styles, but I can't "play" with columns and lines. Is it possible to do this using Model Forms? -

File Upload Multiple Change On Input Gives Unexpected Results
I wrote a fileupload handler in JavaScript to send multiple files using formdata to django. The script works as expected if the user sends multiple files to the server using the input. However, if the user sends multiples files, and then tries to send multiple files BEFORE the last input (of multiple files) has finished, then the program gives unexpected results. Can anyone explain why? Possible solutions: change loop indices create some type of fileupload queue (which I think I already somewhat implemented) disable the input button until the first round of uploads is done processing (last resort) var uploadcount = 0; var folderuploadsinprogress = 0; var uploadfinished = 0; var uploadscanceled = 0; var uploadsize = 0; var fdata = new FormData(); var datalist = []; var xhrcancel = new Set() var xhr; $("#uploadstop").click(function(e){ if(xhrfolder){ xhrfolder.abort(); $("#fu").css("display","none"); return; } xhr.abort(); for(let i=uploadfinished+1; i<uploadcount; i++){ xhrcancel.add(i); } datalist = []; uploadcount = 0; fdata = new FormData(); return; }); function cancelupload(thisid){ console.log('cancel upload ',thisid); console.log('cancel upload finished ',uploadfinished); $("#"+thisid).css("display","none"); //check if canceled upload is a folder if(uploadfinished+uploadscanceled == thisid){ //cancel current upload console.log('cancel current'); if($("#"+thisid).hasClass("folder")){ console.log('has class folder'); xhrfolder.abort(); }else{ console.log('does not have class folder'); xhr.abort(); } uploadscanceled++; $("#"+thisid).css("display","none"); console.log('dl … -
How to set environment variable DJANGO_SETTINGS_MODULE

Django 1 parent table that contains 2 children models, instead of creating 2 children tables

How do I do a Django query filter that matches against a list of values?
Hey guys I'm doing a small social media app and right now I'm having trouble figuring out how to display the posts of users someone is following. Right now I create a list that adds all of the usernames to it as values. How can I filter out the Django query results where it prints out all the results of those contained in the list? I can do it where it prints out only one of the followers posts, since I can compare one value easily. But how can I do the same when I need to compare to a list of values? Any ideas? Thanks guys. Below is my code: def follows(request, username): # create list list = [] # get the username of the signed in user userSearch = User.objects.get(username = username) # get the user ID of the signed in user userID = userSearch.id # get the user IDs of the followers of the signed in user query = Follow.objects.filter(follower_id = userID) #get the usernames of the followers of the signed in user query2 = User.objects.filter(id = query[0].following_id) #add the usernames to a list for i in query: list.append(i.following_id) query3 = NewPost.objects.filter(username = query2[0].username) paginator = Paginator(query3, … -
