Thanks for the link. Using a wrapper is one of the things I had tried.
Here is what I tried. I *think* I'm close, but I don't see the last
little bit that I'm missing:
#### models.py
class Foo(models.Model):
charfoo = models.CharField(maxlength=10)
class Goo(models.Model):
chargoo = models.CharField(maxlength=10)
foo = models.ForeignKey(Foo, editable=False)
#### snippet from urls.py
(r'^goo/create/foo_id/(?P<foo_id>\d+)/$',
'myproj.myapp.views.handle_goo_create'),
#### views.py
def handle_goo_create(request, foo_id):
return django.views.generic.create_update.create_object(request,
Goo,
post_save_redirect = "/goo/%(id)s/",
extra_context = {'foo_id' : foo_id})
#### goo_form.html
{% extends "base.html" %}
{% block content %}
{% if form.has_errors %}
<h2>Please correct the following error{{ form.error_dict|pluralize}}:</h2>{%
endif %}
<form action="" method="post">
<!-- NOTE: i've also tried name="foo_id" and some other variations
of id="id_foo_id" etc some what at random -->
<input type="hidden" id="id_foo" name="foo" value="{{foo_id}}">
<label for="id_chargoo">chargoo:</label> {{form.chargoo}}
{% if form.chargoo %}*** {{form.chargoo.errors|join:", "}}{%
endif %}
<br/>
<input type="submit">
</form>
{% endblock %}
When I view this page with the URL:http://localhost:8080/goo/create/foo_id/1/
I see that the foo_id value is populated in the form, but when posted I
get:
OperationalError at /goo/create/foo_id/1/
(1048, "Column 'foo_id' cannot be null")
Request Method: POST
Request URL: http://localhost:8080/goo/create/foo_id/1/
Exception Type: OperationalError
Exception Value: (1048, "Column 'foo_id' cannot be null")
Exception Location:
c:\Python23\lib\site-packages\MySQLdb\connections.py in
defaulterrorhandler, line 33
Any hints would be greatly appreciated.
Strange... I had the same kind of problem yesterday, that I solve here:

The solution is really close to your. Note: you're right, in the hidden
input, the name is "foo".
