Re: Model validation across relationships

[Joshua Pokotilow]

Thanks for the reply. I had a (perhaps unreasonable) malaise that 
validation should be limited to the fields on a single model.

All purpose type checking

[Lee Hinde]

I have a search form that lets a user pick the field to be searched from a
pop-up. They could enter a date, a string or a number. Sometimes they enter
all of the above and I'm only expecting one of the above.

GET:,

I'm not catching type errors very gracefully and I'm wondering if there's a
general approach to such things, or if I need to hard code the each test.

Managing translations on a team project

[Tyler Wymer]

We have finished translating our application into a second language, but 
are having trouble finding a good solution for keeping this up to date 
going forward. Currently we have just been sending the .po file to the 
translator, but as we hope to have the dual language support not be a 
"beta" thing, we need to find a more serious way to handle this.

We have about 12 developers spread around the world working full time on 
the project, which means that strings change rapidly and it's hard to keep 
up on what is needed for translations before the list gets rather long. Can 
anyone recommend blogs or tools that can help manage this problem? We would 
basically love some way to get a list of strings that are currently 
untranslated generated automatically so our translators can know what needs 
done.

We looked into using the django-rosetta project, but seems like it wouldn't 
work well with our deployment process.

Django Registration Customization Problem

[Abbas Sheikh]

Hello All,

I want the following registration workflow in my app.

   1. User enters his email and is automatically logged-in to the app. The 
   user can play with the app, and it would logout the user after 30 minutes.
   2. Meanwhile an activation email goes out to user's email that would
  1. Confirm his email address
  2. Redirects the user to a new page where he enters his first/last 
  name and password
  3. User can now login to the app his new password.

To implement this workflow, I customized registration 
backend(registration.backends.default.DefaultBackend). Specifically, I have 
override the 'post_activation_redirect' method to redirect the user to his 
profile update page. Where he enters his name and password and submits 
data. 

> from registration.backends.default import DefaultBackend
>
> class CustomBackend(DefaultBackend):
>
> def post_activation_redirect(self, request, user):
> """
> Return the name of the URL to redirect to after successful
> account activation.
> 
> """
> return ('update_user_profile', (user, ), {})
>
However, the problem is that when user clicks on activation link his email 
is validated and activation_key expires. Now if user does not fill his 
profile information at that point in time, the activation link would no 
longer redirect him to profile update page because the activation key has 
expired. 

Please advise how to solve this problem.

Re: loaddata not looking for natural keys

[bobhaugen]

Ok, problem resolved.

I must have done something else wrong the last time I did loaddata, because 
I tried the whole sequence again with the natural_keys as tuples, and it 
all worked.

Sorry to bother the list so much.

But to summarize, natural_keys must be tuples, not single unicode values.

Re: loaddata not looking for natural keys

[bobhaugen]

Not a tuple, it's now a json array. (Still not seeing things accurately...)

So I would think it would deserialize with __iter__, but I still get the 
same deserialization error message.

Re: loaddata not looking for natural keys

[bobhaugen]

Got a clue. I re-read the doc and it says the natural  key value must be a 
tuple.  Missed that before.

So I changed it like this:
def natural_key(self):
return (self.name,)

In the shell, that properly returns a tuple:

(u'Cash Contribution',)


But in the dumpdata results, it is not a tuple:
{
"pk": 22, 
"model": "valueaccounting.patternfacetvalue", 
"fields": {
"facet_value": 4, 
"pattern": 9, 
"event_type": [
"Cash Contribution"
]
}
}, 

So I am still missing something.

Re: Deployment in Django

[Lachlan Musicman]

There's no such thing as a proper Git repository for Django, or even a
proper layout for django.

But you really can't go wrong following the advise offered in Two
Scoops of Django by Daniel Greenfeld and Audrey Roy. First up, they
say exactly that - there is no "right" way. Then they follow with "but
this is how we do it and why" - their experience shines through and
their reasoning is well made and makes good sense.

I've done all my layouts since in the same way, and it works
wonderfully - if only in my own head. Hope that helps.

Cheers
L.
