we can submit foriegnkey data to models through ModelForm
class BooksForm(forms.ModelForm):
class Meta:
model = Books
fields = "__all__"
where in templates we can add
{{form.author}} (author is foriegnkey field in books model)
Im aware that we can submit foriegnkey data using forms like this
but my question is.is there any way where we can submit a foriegnkey object which we have fetched using some other method (with or without form ) to a model(in my case its book)
Let me explain it in detail
lets say for instance there is a Search bar when users search for author, then the function fetches list of authors (choice field) to the user where user can select and submit
which should get populated in the books model
there isnt any proper info related to this on web all i could see is information on how to save data with Foriegnnkey using model form
any kind of insights is appreciated
I'm not 100% sure what your desired outcome is - this is how I understand your issue:
If you want to create a Book entry while passing an Author instance along you could set it as follows:
# models.py
class Author(models.Model):
name = models.CharField(max_length=50)
class Book(models.Model):
author = models.ForeignKey('Author', on_delete=models.CASCADE)
title = models.CharField(max_length=50)
# views.py
def example_view(request):
selected_author_instance = Author.objects.get(pk=1) # example query, adjust to your needs
# Create Book instance and pass author instance along
book_instance = Book.objects.create(
author=selected_author_instance,
title='example'
)
book_instance.save()
return render(...)
