Calculating the /jsi18n/ link

[Seemant Kulleen]

Dear All,

My admin site seems to be misbehaving.  The datepicker and calendar widgets
on the admin site don't show up.  With the help of firebug, etc, I saw that
the problem was that 'gettext' is not defined.  Looking in the page source,
I see this:


> 
> http://media.kulleen.org/admin/js/core.js";>
> http://media.kulleen.org/admin/js/admin/RelatedObjectLookups.js";>
> http://media.kulleen.org/admin/js/urlify.js";>
>
> http://media.kulleen.org/admin/js/calendar.js";>
> http://media.kulleen.org/admin/js/admin/DateTimeShortcuts.js";>


This is from: https://kulleen.org/admin/blog/entry/add/

As you can see, the commented out script line should actually calculate out
to https://kulleen.org/admin/jsi18n/

And sure enough, going to that address shows some javascript (with gettext
defined in it), but going to plain old https://kulleen.org/jsi18n/  does
not.

So the question is this: how is that stuff in the comments getting
miscalculated, and how can I correct that calculation?  I've got django with
apache2 and mod_wsgi.

Thanks!

Seemant

ForeignKey field with null = True and blank = True

[Seemant Kulleen]

Hi All,

Now I'm at ForeignKey funkiness.  So I have the Services model which
has a ForeignKey field to the Sermon model.  The funny thing is that
if I choose a sermon object when I first create a new service object,
all is well.  If, on the other hand, I don't choose one, then it turns
out that I can never choose one.  That is to say, I can choose one,
and hit save and when I come back in it's unchosen.  Happens every
single time.  I've attached the services/models.py and
sermons/models.py if that helps.

Thanks!

Seemant

ManyToManyFields are not syncdb'able

[Seemant Kulleen]

Dear All,

I've attached two files: people/models.py and services/models.py.  I
have two many-to-many relationships defined: one is between people and
roles (each person can fill many roles, and each role can be filled by
many people); and one is between each activity in the service (banner
bearer, crucifer, and so on) and people (each activity can be performed
by many people in a specific role and each person can perform many
activities).  Chris Long and tomaw helped me come up with appropriate
"limit_choices_to" constructs in the services/models.py to restrict each
activity to specific roles -- so that in the admin etc, only specific
people are presented as choices for each activity.  Now, when I run
python manage.py syncdb (with sqlite3 and postgresql both), I get the
following error:


Error: Couldn't install apps, because there were errors in one or more
models:
3crowns.services: no such table: people_role


However, if I remove the limit_choices_to and then syncdb, it succeeds.
If I then re-add the limit_choices_to constructs and run:  python
manage.py reset services I get no errors, and in fact, the admin view
shows exactly what I expect/hope it will show.

This is either a bug with me or a bug with django, and when I think
about it, I reckon it's a bug with me, so I appeal for your help :)

Thanks!
