how to use django model object in django templates?
I am not able to use the Django model object in Django templates. I want to iterate using the model user in the template and then play with the ActivityPeriod(model) of that user. Please check my code for the clarity: Here is my code: views.py from .models import User,ActivityPeriod def call_response(request): user = User.objects.all() return render(request, "Test/list.html", {"users":user ,"activityperiod":ActivityPeriod}) Test/list.html {% for user in users %} 'real_name': {{ user.real_name}}}, 'activity_periods': {% with activity=activityperiod.objects.get(id =user) %} {{ activity.start_time }} {% endwith %} {% endfor %} But i am getting an error: Could not parse the remainder: '(id' from 'activityperiod.objects.get(id' What is the correct way? Can anyone please share it with me. -
Django admin list page takes forever to load after overriding get_queryset method
I have this model admin - class NewsAdmin(ImageWidgetAdmin): image_fields = ['featured_image'] list_per_page = 20 list_display = ('heading', 'category', 'status', 'is_active', 'created_at', 'published_at', 'created_by', 'published_by') list_editable = ('category', 'status', 'is_active') list_filter = ('published_at', 'created_at', 'status', 'is_active', 'created_by', 'published_by',) search_fields = ('heading', 'category', 'tags', 'source') actions = [enable_object, disable_object, status_draft, status_private, status_public] actions_on_bottom = True It only takes max 400ms to load.

How To Change HTML In A Live Editor
For a personal project I am trying to create a theme editor with Angular (version 8.2.14) for my frontend and Django (version 3.0.5) for my backend. I am then using Jinja2 for the various themes. Right now I am stuck on how to have a live preview of the theme with inputs available to change the theme accordingly. Right now in my Angular component I load the Jinja2 template into an iframe. The system works flawlessly on initial load using JSON to set the variables, but I just can't figure out the live editor. I feel as if I am halfway there but missing something. So far I have a function in my typescript that sends a post message on every key press. sendToFrame(event, id) { // event is the keypress // id is what is set to the data attribute const iframe = document.getElementById('preview') as HTMLIFrameElement; if (iframe && iframe.contentWindow) { const message = {'id': id, 'value': event.target.value}; iframe.contentWindow.postMessage(message, '*'); } } then in the head of my Jinja2 theme I receive that message and use vanilla JS to change what I need to. window.addEventListener('message', function(event) { let elementToChange = document.querySelector('[data-theme-editor-setting="' + event.data.id + '"]'); elementToChange.innerHTML = event.data.value; }, … -

Django Web Application, Facebook login
I am building a basic social media web application and I would like my only login point to be via facebook login. After doing a fare amount of research, I have seen multiple third party authorization frameworks that plug in with facebook, but I was wondering if there were any opinions on what the best foot forward would be.

What do I do with all the logic in my django views when converting my project to django rest api with reactJS?
I created a web app all in django. I am now wanting to practice using reactJS on the front end, therefore it seems I need to make my django app an api end point to send and receive json data from reactJS. Now, my understanding is the api views are all very simple just to post and get data. My question is, where do my normal views go? I'd assume these views and logic all now has to go in reactJS front end with JS? For example, one view in my current django app is what to do after user submits a youtube channel in a form. The view goes through all the logic (ie if it exists and is registered, show all the related comments, if the channel exists but not registered, register and save in db, if doesn't exist on youtube notify and stay on current page. This logic has to be now put on front end if I switch to using django rest api? I can't get my head around this. Thanks! -

Django: What could cause duplicate permissions to be created in the auth_permission table?
I'm currently working on a Django app that has been maintained for 4+ years at this point. I joined the team not too long ago. I was getting complaints about group permission issues, and after a lot of inspection, I found out that there were many duplicate permissions. id | name | content_type_id |codename ----+----------------+-----------------+-------- 1 can add x 1 add_x 2 can add y 2 add_y 3 can add y 1 add_y I see this kind of behavior in the table where the name/codename is a duplicate of some other valid entry, but then the content_type_id arbitrarily uses some other content_type_id that doesn't relate to it at all. It doesn't happen to every permission, but there are a quite a few in which it is happening. This is a pattern I have observed if the database that this app is connected to has been continually migrated/upgraded over years, then the auth_permission table seems to have this issue of duplicate permissions with random content_type_id. However, when I run the app on my local with the latest version and run the migrations on a fresh db, I get no such issues. I suspect it has to do something with migrations. Is … -
Better way to deal with private API which doesn't support CORS
I'm working on the Imperva API with axios. After digging the document of the API and doing some tests, the API seems like doesn't support CORS. Since that the Imperva API requires user to send requests with key, I think is not a good idea to use something like cors-anywhere. My current plan is to set up a CORS proxy on my backend server(Django). However, I'm not sure if this is a good way to solve the problem and also not sure if Django can do this trick. Please give me some advices on this. Thanks a lot! -

Django: Static files are not found
I'm trying to add some static files to my project. I have tried adding a static folder to my app. I have two apps: Authentication (authn), Main (main). I have a lot of CSS/js content and I don't really know which is the best method to save the files, maybe all static files should be in one directory 'staticfiles' or each app should have 'static' folder. I have tried adding static folder to one of my apps, at this time - authn. And by trying to load the static files I firstly did python manage.py collectstatic, that put my all files into one folder, but I got two different folders now - admin, main. After tried putting all my static files into a static folder in authn app, but the static files were not loading after that. Here are my project structure and some photos and logs of the console, pycharm.
