Issue in making changes on the site, hosted on pythonanywhere
I'm hosting my blog site on pythonanywhere. I also have a model field for subscribers in the database.

How to use User Model defined in models.py for Authetication in Django Rest Framework
What I want to do 1.Introducing authentication in Django Rest Framework 2.Doing authentication using User model I defined in as models.Model, not admin-user provided by django by default. Version django : 3.1 djangorestframework:3.11.1 python : 3.7.6 Situation I am trying to creating an app that each user can exchange their items. I use Django in server side, and React in client side. In order to introduce authentication and registration, I created User model in models.py. However, when I try to introducing these features in Django Rest Framework I notice that I may not be able to do that using User I define, perhaps I have to use admin-user django provides. Question __ First of all, can I introduce authentication and registration features using User model I define myself ?__ I found I can edit admin-user itself so I edited it. It doesn't work. Honestly, I don't understand whether I can introduce these features using User model as well. I would like to teach me how to figure it out. And I would like to those who have combined Django and React to teach me some way to realize authentication and registration. Thank you very much. This is my User model. … -

Order of Values from a Django Foreign Key Reverse Lookup
I have two models, Document and DocumentImage. Document has a primary key called document_id, and a foreign key to DocumentImage. Say I have a list of document_ids and I run this query: images = DocumentImage.objects.filter(document__in=document_ids) as a reverse lookup through the foreign key relationship Is it true that images[0] is derived from document_ids[0], and images[1] is derived from document_ids[1], etc? I need to combine each element in images with each element in document_ids, and I want to make sure that I have the correct document_id for that element from images. In other words, I want to do this: for document_id, image in zip(document_ids, images): # associate the document_id with the image and make sure that each image is associated with the correct document_id.

How do I consume data from Django Rest Framework API with frontend javascript (separate repository)

How to check if value from a field in a table object is equal to specific string in django template language?
I am iterating over all the entries in a django table called Ideas. One field in the table is status, and I want to check if the status is equal to some specific string. I have already checked that I am accessing this field correctly, with idea.status in my case, but I can't find how to compare that entry to a specific string in the django template language docs. I am trying to change a table's cell color based on what is in that cell. Here is what I tried, but to no avail: {% for idea in ideas_list %} ... {% if idea.status == 'Not Started' %} <td style="background-color:red;"> {% elif idea.status == 'Completed' %} <td style="background-color:green;"> {% elif idea.status == 'In Progress' %} <td style="background-color:yellow;"> {% else %} <td> {% endif %} {{idea.status}} &nbsp;</td> ... {% endfor %} My page is still rendering with the status text in the table, suggesting to me that all the if's were failed, which would end in the else condition being met, giving <td>{{idea.status}} &nbsp;</td>, with no cell color, and suggesting to me the problem is in my if statements themselves. -

I use token authentication for the ease of use, however, I don't understand/can't imagine how I can limit the amount of requests a user can make on a per month basis. Or give a limited amount of requests to an anonymous user. Should I create a custom permission class ? ### settings.py ## INSTALLED_APPS = [ # basics 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'django.contrib.sites', # API 'rest_framework', 'rest_framework.authtoken', # auth 'rest_framework_tracking', # logging ] ## views.py ## class MyAPIView(APIView, LoggingMixin): logging_methods = ['POST', 'PUT'] authentication_classes = [TokenAuthentication] permission_classes = [IsAuthenticated] renderer_classes = [BrowsableAPIRenderer, JSONRenderer, CSVRenderer] parser_classes = [JSONParser, MultiPartParser] def post(self, request, proba=False): query = request.POST.get('q') content = { 'result': "Model predictions." } return Response(content, status=status.HTTP_200_OK)
