you can try something like that:
group = ...
choices = [(product.pk, product.name) for product in
group.product_set.all()]
form.fields["myfield"].choices = choices

Hi,
My checkboxes are giving me grief.
I want to make it required for the user to check a checkbox before being
allowed to submit a forms.
I'm using model forms so the checkbox is defined as a models.BooleanField
in my models.py. I have included blank=False, though this should be the
default.
I too have the same problem. How did you fix it?

Read the above reply.
When you print form.error --> prints out a custom __unicode__ for you to
use in your templates.
However, you can iterate over form.errors and it will act as a normal dict.

It seems in this particular case you don't need the boolean field in the
model. As the behaviour you want has to do only with the form, you just
have to add an additional required checkbox in this model form.
class MyModelForm(forms.ModelForm):
involved = forms.BooleanField(required=True)
clas
I'm going to assume that we're talking about a single checkbox (an "I
agree to the terms" checkbox).
First, remember that unchecked is not the same as "blank", it is
"false", so "blank=False" is subject to interpretation.
There are two places where you might insist that the box be checked:

As a quick hack, you could generate a postscript file using savefig().
Then, you could print that from the commandline to a local printer--If they
don't need a physical printout, I would generate a pdf file and serve it to
them and let them print it. If I figure out how to print directly using

If you need to draw a graph, you can try the pygraphviz.
If you need to plot a chart, you can matplotlib, if that is not
so easy to implement, you can try using django google chart
If you can convert the Graph into an image (file or object) than you could
use PIL (Python Imaging Library) to dynamically generate an image and serve
it via a dynamically generated link.
