Django REST framework: Unable to use custom template for login view
Gist: I'm trying to use a custom template for Django REST framework's login view by following the instructions from official documentation, but the template that I have put at <PROJECT_ROOT>/templates/rest_framework/login.html is not used to render the login page. Detail: I'm trying to properly set up Django REST framework's browsable API. In particular, after a successful login, the login view redirects to LOGIN_REDIRECT_URL, which has a default value of '/accounts/profile/' and is not what I need. I figured there are two possible solutions: to assign a value to LOGIN_REDIRECT_URL, or use a custom template for Django REST framework's login page and modify the HTML form to pass 'next': <MY_REDIRECT_URL> as the form data (I've tested this manually and it works). I decided to go with solution #2 because solution #1 is not ideal because that would be setting a global default to change behavior of one specific part of a subsystem. Solution #2 requires using a custom template for the login view, but I'm unable to get it to work by following the official instructions (link above). Things I have tried: I have tried the solutions in the following Stack Overflow questions: Django REST Browsable API Template Change django drf login … -

Django UniqueConstraint on related model property
I have a model that looks like this, and it works ok: def BookModel(TimeStampedModel): user = models.ForeignKey(User, on_delete=models.CASCADE) bookname = models.CharField() class Meta: constraints = [ models.UniqueConstraint(fields=['user ', 'bookname'], name='StackOverflow.Question') ] Each user can only have one BookModel with a specific bookname. However, now I'd like to introduce the concept of LibraryModel class LibraryModel(TimeStampedModel): user = models.ForeignKey(User, on_delete=models.CASCADE) name = models.CharField(max_length=32) def BookModel(TimeStampedModel): library = models.ForeignKey(LibraryModel, on_delete=models.CASCADE) bookname = models.CharField() class Meta: constraints = [ models.UniqueConstraint(fields=['library_user', 'bookname'], name='StackOverflow.Question') ] Behavior should stay the same: the constraint should still be enforced based on the associated user, but the user id now lies within LibraryModel. When I run migrate, it says django.core.exceptions.FieldDoesNotExist: BookModelhas no field named 'library_user'. I've also tried fields=['library__user' and fields=['library.user', to no avail. Is this possible to do? Or should I put the user property in both models, violating some DRY principles? -

Query model for objects that do not have an associated child object
I am trying to display summary information about child objects, and about child objects that do and do not contain grandchild objects. Two of the three work, but not very well. I am not able to get a result set at all looking for child objects that do contain grandchild objects, though the result for objects that do not contain grandchild objects works.

Cannot make requests to APIs without auth token after added "WSGIPassAuthorization On"
We had a issue after deploying Django to AWS. The problem is that We cannot make requests to the APIs whose permission classes is set to "IsAuthenticated", even if we put the auth token in the header. permission_classes = (IsAuthenticated,) We can only make requests to the API whose permission_classes is set to "Allowany" After reading this post Authentication credentials were not provided. when deployed to AWS, We have figured out that it was the authorization header did not pass through. after we used the following command: 01_wsgipass: command: 'echo "WSGIPassAuthorization On" >> ../wsgi.conf' The exact opposite thing happended. The auth token somehow become mandantory. We can make request with auth token in the header only to the API whose permission classes is set to "IsAuthenticated". Making requests to the APIs with permission_classes set to "Allowany" returns 401. How do we fix it? Thanks in advance. -

Auto Fill Text field from one text field to another with small change
Is there anyway to auto populate fields based on user input from the 1 text field, then update rest of the fields with small changes in each field. For example: [user input] Field 1 Network: 192.168.0.0 [auto] Field 2 Network_Util: 192.168.1.0 [auto] Field 3 Network_Util2: 192.168.2.0 I tried to for following code, but it copies the text, how to change the third octet value? <input type="text"id="network1" name="Network1" value="" > <input type="text" id="network2" name="Network2" value=""> $("#network1").keyup(function(){ var net = network1.split("."); var octet3 = net[2]; $("#network2").val(this.value); }); Thank you for your help -
Are atomic transactions supposed to produce more connection.queries in Django?
I have the following in my models: from django.db import models class X(models.Model): ... class Y(models.Model): ... x = models.ForeignKey(X, on_delete=models.CASCADE) class Z(models.Model): ... y = models.ForeignKey(Y, on_delete=models.CASCADE) In one of my views, I am updating all my models like so: from .models import X, Y, Z from django.db import connection, transaction def do_something(bro, z_pk): z = Z.objects.select_related('y__x').get(pk=z_pk) y = z.y x = y.x ... with transaction.atomic(): z.save() y.save() x.save() print(len(connection.queries)) With the transaction.atomic(), the length of queries is 5. However, without it, the length returned is 4. That is, the following code: from .models import X, Y, Z from django.db import connection def do_something(bro, z_pk): z = Z.objects.select_related('y__x').get(pk=z_pk) y = z.y x = y.x ... z.save() y.save() x.save() print(len(connection.queries)) Returns a length of 4. Is this normal or am I missing something? Moreover, with the transaction.atomic(), am I hitting my database less times? Its difficult to understand that based on the connection.queries. Note: The extra query in the atomic function is the following: {'sql': 'BEGIN', 'time': '0.000'} -
A Desktop application for Django
I'm making a little Time Attendance Django Application where I want two parts of that program. A web part and a Desktop part. The Web Part would be used to view the Employees, Manager them, get payroll whereas the Desktop Part would be used to add attendance and stuff. And before anyone asks, I'll be using facial recognition for the attendance. So unless there's a way to use good and fast facial recognition on the web, I can't do it all on the Web. I was thinking of using electron. Make things simple. Have two login types, one for the web and the other for the Desktop. If that's the case, I would like to have different views and templates for the both of them without making a new app. Maybe add an option on the login page where you can choose either Desktop login or Web login. (Let me clear this here that by Web Login, I mean the Website like how you put in the URL in the browser and by Desktop Login, I mean the same thing but outside a browser. I understand that Electron is a browser but I hope you understand xD) If this is … -
