Re: Get Form from string?

Hey MacVictor,

So when I needed to do something similar, I landed up hard-coding a dict with form-name -> form-class in my model definition. Honestly, there is probably a better way to do it, but that worked fine for my use-case, though it did feel slightly "not right". Any-how, fwiw, I did something like:

from forms import FormA, FormB, FormC

class Foo(models.Model):

  ...

  forms = {

    'SomeFormA': FormA,

    'SomeFormB': FormB,

    'SomeFormC': FormC

  }

And then in your view, something like:

form = model.forms[<form_name>] .. etc..

I'm guessing from your email that what you need is something similar, and perhaps someone from the list has a better idea than the above to do it ..

Hope that helps, though ..

All the best,

Sanjay

I try in view get the form by name.

Example:

this is my url: 

/some-url/MyForm/

url(r'^/some-url/(?P<form_name>[a-zA-Z0-9]+)/', 'my_view', name='my-wiev'),

and my view:

def my_view(request, form_name):

    form = how_get_form_name(form_name)

    response = {}

    response['my_form'] = form

    return render_to_response('request/window.html', response)

I have create uniwersal view, get my form and send to template. Why form? Because my model has more Forms and I want to select which forms.

I am afraid, I did not understand your question. Are you trying to generate a form based on your model/ models?

how to get ModelForm by string?

i try used:

modelforms = forms.ModelForm.__subclasses__()

def get_form(form):

    try:

        for model_form in modelforms:

            try:

                if model_form.Meta.form == form:

                    return model_form

            except AttributeError:

                continue

    except IndexError:

        print "Does not exist Model Forms for the object"

but I must import the form in which I will seek appropriate by name!
