Uploading multiple images in one field using django rest framework

Django Admin get_queryset with RawQuerySet
I'm developing a product for a client and I've come across the following problem: There's a model I'm working with a RawQuerySet, and I need to show it in the index of this particular application, but by defining get_queryset() inside the ModelAdmin, the application breaks. However if I enter an item directly, it reads it and works correctly. I've been working on this for a day and a half now and I can't think of anything else to do to try and fix it. This is how the get_queryset method looks like: class QuestionnaireAdmin(admin.ModelAdmin): def get_queryset(self, request): return Questionnaire.objects.raw("SELECT * FROM........") And when I enter the admin site of Questionnaires index, this is what I get: Admin Site Error Picture Also, the console doesn't return anything when this happens so I'm a little lost. I'd appreciate any kind of help. Python version is 3.7 and Django version is 2.2 -
django-rest with multiple url parameters
Using djange-rest framework along with Django 3.0 In my urls.py i have these lines: router.register('search/(?P<param_1>\d+)', SomeView, basename='someview') router.register('search/(?P<param_1>\d+)/(?P<param_2>\d+)', SomeView, basename='someview') I have a problem accessing the second url parameter in the second line. It seems like the first line changes the parsing of the second param of the second line. In the SomeView class the self.kwargs dictionary has 'param_1' and 'pk'. If I remove the first line, it all goes well, i get the dictionary populated with 'param_1' and 'param_2'. Is it a weird behavior, or am I missing something? How do I get 'param_2' in the dictionary in this case? -

I am a beginner in Django and I'm trying to learn. I can't figure out the cause of the error, the template name is defined as per the documentation students/student_detail.html.

So, how can I use the form to repeatedly query the model with each use being independent. the outcome of the … -
queryset based on related model
I've got two models. One (FAQ) is related to the other (FAQCategory). I'm trying to develop a queryset of FAQCategories that are assigned to FAQs, but only if at least one of the FAQs has both the question and answer filled in. class FAQCategory(models.Model): title = models.CharField(max_length=50, null=True, blank=True) def __str__(self): return self.title class FAQ(models.Model): category = models.ForeignKey(FAQCategory, on_delete=models.SET_NULL, null=True, blank=True) question = models.CharField(max_length=100, null=True, blank=True) answer = models.TextField(max_length=10000, null=True, blank=True) For example, we have 3 FAQCategories 1) General 2) Shipping 3) Warrenty 1) General is not assigned to any faqs. It should not show up in the queryset 2) Shipping is assigned to a FAQ instance, but that FAQ doesn't have an answer on it. Shipping should not show up in the queryset 3) Warrenty is assigned to a FAQ. That FAQ has both an answer and a question value. As a result, Warrenty should appear in the queryset.

Django Rest Framework and React Front End: How to serve sensitive images only to the user that has the correct Token authentication?
My understanding is that on a normal React website all the media will be served from the same server than the front-end files (HTML, CSS and Javascript). The REST API backend will only provide links to where those images are stored, and it will be served and displayed by the front end. The problem is if those images are private and only one user should be able to see them. If someone gets ahold of the image link and opens it they would be able to see the image. How do modern websites get around this problem? What would be the workflow between Django and React to keep the user's images safe and private? Can the private images be stored in the REST API server and only be sent as a response to a user if it has the proper token? Many thanks in advance! -
