Re: can't add via admin, get django template error
I had defined a custom admin class for that model. I commented it out
and went with the default admin class, and got the same error trying
to create a new record. So didn't think it was the admin.
Then I looked at the date fields on that model. Turned out that
specifying a default date as a string was the problem:
publish_date = models.DateTimeField(default='2039-12-31') # don't!
Even though it works with a standard ModelForm form, ie gets displayed
in the UI properly, is accepted as a valid date by the Form
validation, and gets inserted into the db properly.
I think that the admin should accept such a (properly formed) date
string. Or else the model shouldn't validate.

I would guess that the problem lies somewhere in your admin file
(admin.py). What are the contents of it?

can't add via admin, get django template error
So I'm working along, everything's humming fine. Then I try to add a
record via the admin, and get the following:
TemplateSyntaxError at /admin/expert/expertresponse/add/
Caught AttributeError while rendering: 'unicode' object has no
attribute 'date'
[snip]
Template error
In template c:\python26\lib\site-packages\django\contrib\admin
\templates\admin\includes\fieldset.html, error at line 12
Caught AttributeError while rendering: 'unicode' object has no
attribute 'date'
2 {% if fieldset.name %}{{ fieldset.name }}{% endif %}
3 {% if fieldset.description %}{{ fieldset.description|safe }}{% endif %}
4 {% for line in fieldset %}
5
6 {{ line.errors }}
7 {% for field in line %}
8
9 {% if field.is_checkbox %}
10 {{ field.field }}{{ field.label_tag }}
11 {% else %}
12 {{ field.label_tag }}{{ field.field }}
I can add records via a ModelForm without problem, it just doesn't
work in the admin.
