How to do custom fields on init from serializers?

[Johnny W. Santos]

I want to make fields with custom behaviors just like in django forms. Can i do that with serializers to?

I tried this just to create a field like on forms:

def __init__(self, *args, **kwargs):

    self.fields['pdf'] = serializers.FileField()

but returns:

AttributeError at /edicoes/nova/

'EdicaoSerializer' object has no attribute 'fields'

Where can i found some documentation about this?

Call the superclass __init__ first.  That'll work.

You won't.  I'd probably consider this a private API, at least for now.

I did this, but the pdf field don't show in form.

class EdicaoSerializer(serializers.HyperlinkedModelSerializer):

    

    class Meta:

        model = Edicao

        exclude = ('data_file', 'zip')

        

    def __init__(self, *args, **kwargs):

        super(EdicaoSerializer, self).__init__(*args, **kwargs)

        self.fields['pdf'] = serializers.FileField()

Okay, I got the impression you wanted to dynamically add fields to your serializer for some reason.

What you're looking for  is doing pretty much that same thing you would do with a ModelForm.

    class EdicaoSerializer(serializers.HyperlinkedModelSerializer):

        pdf = serializers.FileField()

        class Meta:

            model = Edicao

            exclude = ('data_file', 'zip')

This is documented here.
