Question

How do I assign initial values to fields inside a ModelForm? eg:

class Form1(forms.Form):
    title=forms.CharField(initial=\"hello\")

What wil

Answer 1

Model Form defaults are taken from the model itself. For example:

class SomeModel(models.Model):
    title  = models.CharField(max_length=45, default="hello")

You don't need to make any changes to your ModelForm:

class RequestForm(forms.ModelForm):

    class Meta:
        model = SomeModel

Answer 2

Normally you would pass the model object you are editing as instance keyword arg to the form: Form2(instance = somemodelobject), but I don't know if it works on GAE. You can always pass initial dictionary to your form's constructor, like

Form2(initial = {"title": "blahblah"})
