Django ModelForm with foreign key

Question

I\'m trying to create a ModelForm that updates a table with foreign keys. What I have seems to work, but I was hoping someone could tell me if there\'s a bette

Answer 1

The only thing that's wrong with this code is you are overriding the default behaviour of your model form. Change it to look like:

class BookForm(ModelForm):

    class Meta:
        model = Book
        fields = ['title', 'author', 'genre']

And let django handle with the definition of those. if you need to add labels or widgets, you can define them in the Meta class:

class BookForm(ModelForm):

     class Meta:
         model = Book
         fields = ['title', 'author', 'genre']
         labels = {'title': 'Book title', }

For example.

Answer 2

I'm not really sure what you're asking here, or why you would want a queryset on Book.

You haven't actually changed any of the defaults on any of the fields, so there is no need to redefine them: your form could be simply

class BookForm(ModelForm):
    class Meta:
        model = Book

and it would work exactly the same.
