Leaflet widget is not rendered automatically for forms.Forms

[faaizajaz]

Hi, and thanks for this fantastic project (and django-leaflet).

Using the leaflet widget on modelForms (where the model has a corresponding geom field, e.g. PointField()) works as expected, however when using forms.Form the behavior is not consistent.

The docs say that form widgets are rendered with Leaflet automatically if django-leaflet is available, but this does not seem to be the case.

Taking a simple example:

class SampleForm(forms.Form): location = djgeojson.fields.PointField()

From the docs, we expect that when this form is rendered, there will be a leaflet widget for the location field, which does not seem to work.

GeoJSONField is the model fields. You must use GeoJSONFormField in a form.

class SampleForm(forms.Form):
    location = djgeojson.fields.GeoJSONFormField(geom_type='POINT')

Thanks Gagaro, this works and looking at the djgeojson/fields.py I can see why. It's not immediately obvious to me why this is not required when using forms.ModelForm. In that case, the PointField is automatically rendered as a leaflet widget, which is the behavior expected from reading the docs. I guess this has something to do with forms.ModelForm itself?

Perhaps it would be useful to update the documentation for both the ModelForm and Form use cases?

I'm not sure why it would work in some cases.

Feel free to update the docs and do a PR or point where in the doc it is, I'll try to update it when I find some time.

Sure, I will take some time this week to test and update myself.
