Development of Django project, code exception, automatically locate the exception to the code segment after the project is overloaded
Question: This is the case, I use VsCode to develop Django projects, I haven't finished writing a piece of code, but due to my operating habits, I will often ctrl + s, or the automatic save function provided by Vscode will save my code. At this time, the running Django project will be automatically reloaded, and because my code is not finished, reloading Django will definitely throw an exception, and Vscode will automatically locate the page where I wrote the code at this time. Where is the code segment where the exception occurs. Originally, I was happily writing code, and suddenly the page jumped to another location, which was terrible and greatly affected my development. I just switched from pycharm to vscode. This problem has affected me for several days. If it can’t be solved, I can’t use vscode to develop happily. I hope that vscode will not help me locate in my editing interface, it is enough to throw an exception in the terminal below. Friends who know the solution, please feel free to enlighten me~~~ Thank you My troubleshooting process: I tried my best to find the various settings of vscode, but I couldn't find the corresponding configuration … -

Problem with save method overriding attribute value
I have a model called 'Trip' with a Foreign Key to 'Destination'. The Destination model specifies a maximum number of passengers in it's 'max_passengers' attribute.

Django Models How To Upload Multiple Files For One Field
I'm looking to upload multiple images from my front-end form (VueJS) to my 'photos' field. However, even with my foreign key, I can only link one image at a time. (I tried ArrayField too, but didn't work) I know with Django forms.Form there's a widget option for 'attr multiple = True', but I can't seem to find a solution for models. class Photos(models.Model): photos = models.ImageField(upload_to='uploads/', null=True, default="") class Actors(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.PROTECT, default="") Writing_Samples = models.FileField(upload_to='uploads/', null=True, default="no samples") photos = ForeignKey( Photos, on_delete=models.CASCADE, default="", null=True) gallery = ArrayField( models.CharField(max_length=100), blank=True, default="") Thanks for your time! -
How to login in Django Rest Auth using username or email
In my django project, I am using django rest auth for api authentication. The default is to use username and password for login. I can also use email and password. But I want my user to have the option of either using email or username and password for login authentication; which I believe is more user friendly. How do I do this in django rest auth? -
django.db.utils.OperationalError no such table
Good evening, I am wondering what may the cause of a 'no such table' error in django. I have three databases defined in settings: a 'default' sqlite3 one and two postgresql ones. Out of my models defined in models.py, only one is specifically routed to 'default'. The other models have no routing settings set since they are meant to exist in all postgresql databases, just with different data. I write Model.objects.using(DBname) everywhere to make the DB access explicit. Migrations to all three of my databases were initially successful and, based on DB Browser and phAdmin, they all have the correct fields and data. In the 'context' variable sent to each rendered template, I send only the queryset after Model.objects.using(DBname), but within the template Django cannot see the tables. What could be the reason for django not being able to see them? What I think may be happening is that because the 'table not found' relates to a ForeignKey field of one of my models (a through table), Django is attempting to look for that model in the 'default' database instead of the database chosen during .using(). Does anyone possibly have any experience with anything like this? -

Django Rest Framework AttributeError: Got AttributeError when attempting to get a value for field
I have been trying to add attributes to the UserProfile by creating a OneToOneField to User and adding different fields. Now I run this and call the api with the body below. The api is able to successfully get parsed. A user gets created in the user table and user profile table with the correct attributes.

Auto display the form's data in other view (django)
I'm using django forms to get some data from the user. It works well with the DB. How can I display that data (in a different page) right after submitting? The flow should be: The user fills the form Clicks submit (creates an object and saves to DB) The user is redirected to another page in which the data he just submitted is presented. Basically I need to pass the object's PK (the one the user just created) from one view to another. It's supposed to be fairly simple yet I couldn't find a decent solution for that issue. Thanks! -
