Getting validation error field can not be null, even if null=True in model
I've a foreign key in my model and this field can be null. status = models.ForeignKey(Status, on_delete=models.SET_NULL, null=True, blank=True, related_name="status") When i send a request with this field as null i get validation error saying [ { "status": [ "This field may not be null." ] } ] Even though I have set null=True I'm not sure why it's throwing me that validation error? Can anyone please help me with this. -
How to create a validation check that ensures the right-formatted directory path is stored and if it contains a file extension in Django?
I have a template that allows a user to store a pathname of a directory in my model (the directory should be available/exist in the server for a website or seen in a local machine). Before saving the path to the model, I need to ensure whether if the right format for the directory is being saved. Example: var/www/html/media/product or C:\Users\Danny\Desktop\folder. There shouldn't be any irregular strings, expressions or invalid format seen in the path like var/www/html/media/product\pic/... Moreover, I want to stop users if they want to save a specific directory path that contains a file extension. Example: var/www/html/media/product/file.<'file extension'> ('file.png', top.txt', 'random.jpg', etc...) How can this be done in my views.py code? Currently, this is what I did so far: views.py: def dashboard(request): if request.method == 'POST': form = PathForm(request.POST) if form.is_valid(): path = form.cleaned_data['path'] #CharField that stores the path name in model from form. #Two checks required. Need to see if it is a valid directory path format or if the path contains a general path directory. Not specific files (like images, text, csv file) should be seen in the path. #if file path contains a file extension at end. This is tedious since I need include all … -

Define a path for a file in python script on heroku

How to sync local Django sqlite3 data with Heroku's postgres database?
I have a Django website served by Heroku with a model storing data about projects that I've worked on in the past. I already ran makemigrations and migrate locally before pushing to heroku with git and running heroku run python3 manage.py migrate. So, my database models and fields are synced, but I'm asking about the field values. Whenever I update the value of a field for a model instance locally, I want it (the data) to sync with Heroku, and vice versa–sync values I've updated on Heroku in the admin panel with my local sqlite3 database. Is there a command for updating the values of the database itself, or am I missing something? Because I've looked all over the internet for the last hour for how to do this one thing. Side note: I also want the command I'm looking for to sync newly created instances, not just data for existing model instances. -

Django template won't render form errors
After a user has submitted a form with data that fails validation, form.errors in fact collects those errors as I've been debugging the issue. However when I render the page after a POST request, the errors will not be parsed in HTML alongside the fields where errors occur.

Bulk Update of model fields baseds on user input in admin site
In django, let's say I have a model with an integerfield called "RouteNumber" in my model. I manage all the model entries in the django admin site and I want to assign a route number to more than 100 entries at a time. How can I do that based on a user input?

Is there an easy way to get that? Thank you for your answers -

Slow Django Page - Doesn't Appear to be caused by SQL
I'm trying to debug a slow Django listview page. The page currently displays all tests (133), as well as the latest result for each test. There are approximately 60,000 results, each result having a FK relationship to a single test. I've optimized the SQL (I think) by selecting the latest result for each test, and passing it in as a prefetch related to my tests query. Django Debug Toolbar shows that the SQL is taking ~350ms, but the page load is ~3.5s. If I restrict the list view to a single test though, the SQL is ~7.5ms, and page load is ~100ms. I'm not fetching anything from S3 etc, and not rendering any images or the like. So my question is, what could be causing the slowness? It seems like it is the SQL, since as the result set grows so does page load, but maybe rendering of each item or something similar? Any guidance on what to look into next would be appreciated. -

How to properly filter or exclude based on a parameter in Django?
I can do this in Django: query = {field_name: value} if include: return queryset.filter(**query) else: return queryset.exclude(**query) That's bad because there's a fair bit of duplication, and it's rather verbose. I can also do this, which is much simpler: return queryset._filter_or_exclude(not include, field_name=value) But that's also bad, because I'm calling a protected method. Is there a way to combine the best of both? return queryset.filter(exclude=not include, field_name=value) is not a thing.
