Re: How does the default option for a field work in the model?

[Andrej]

I want to use the Admin module to pre-set default values when creating
the form. For example, in the gender case, I want to have default
"Unknown" option. Is this this not possible?

Re: Serving https with runserver

[Andrej]

because you need to load apache ssl gear. Set up your normal virtual
host and then use reverse proxy:

ProxyPass / http://localhost:8000/
ProxyPassReverse / http://localhost:8000/

How does the default option for a field work in the model?

[Andrej]

>From the docs:

GENDER_CHOICES = (
('M', 'Male'),
('F', 'Female'),
)

Shouldn't this work? It's a tuple.

gender = models.CharField(_('Gender'), max_length=1,
choices=GENDER_CHOICES, default=GENDER_CHOICES[2])

It doesn't.
I smell black magic!

Please help :)

Re: Conditonal validators for the model

Thanks for the reply, that definitely works, and it's within the MVC
paradigm.

Conditonal validators for the model

[Andrej]

Greetings,

Django is awesome! I'm playing around and I was wondering if there is
a way to specify conditional validators in the model.

Example: if field x is blank, field y is required.

Thanks for your help!

Re: making two-column table from one-column data

[andrej kesely]

Thanks for your reply, I really like the general iterator approach.
This recipe will definitely go to my personal "standard" library.
