Re: Database operators for custom fields
Hi! In python, '==' operator is set to '__eq__' and '!=' operator is set to '__ne__' functions. See more details in http://jcalderone.livejournal.com/32837.html And In order to make queries from the ORM, Django uses Managers https://docs.djangoproject.com/en/dev/topics/db/managers/ So you can write a Manager for the model that has this custom field, override the __eq__ and __ne__ operations on this custom field and implement as you like.

Re: Newbie Question - Where to store application constants?
Kirby, You have a good point. However, in this use case I am dealing with a jewelry store buying gold at their "market" rate. It is not the same as owning gold and the value changes based on a published (ie available through an API) rate. The jewelry store market rate for gold changes slowly, and from store to store So, I found creating a table called constants in the database allows me to change the value as needed and not have to touch the app code.

Newbie question about django-cas
Hello. I am trying to put together a little test application which allows a user to log in to a CAS server and then redirects them back to the site after they have logged in.

The URL for my server is: login.oregonstate.edu-dev/login However, when I try to access http://127.0.0.1:8000/accounts/login, I get redirected to: http://127.0.0.1:8000/accounts/login/login.oregonstate.edu-dev/login?service=http%3A%2F%2F127.0.0.1%3A8000%2Faccounts%2Flogin%2F%3Fnext%3D%252F Can anybody point me in the right direction as to what's going on here? -- You received this message because you are subscribed to the Google Groups "Django users" group.

platform for mainstream enterprise applications
I am a Django newbie. I expect that Django could be a good platform to build a force.com like application platform: a platform where business experts can define business data models, authorization rules (which user role can access or edit what parts of a model in what state) and workflow rules. I wander if there are already initiatives out there to build this type of platform, or components of it? For instance I found on the internet some discussion around dynamic models (classes) exploiting meta-programming facilities of Django. That could be the foundation of such platform.

Re: Database operators for custom fields
If I am not mistaken you are trying to alter how .filter(customfield__eq=val) and friends work. In current Django versions you can't easily customize the SQL generated for ORM lookups. In Django 1.7 (currently in alpha) this is possible using custom lookups. Custom lookups will allow you to alter the SQL generated for different lookups (and also add new lookups if need be). See https://docs.djangoproject.com/en/dev/ref/models/custom-lookups/ for all the details. - Anssi On Wednesday, February 19, 2014 1:45:43 PM UTC+2, johannes.schneider wrote: > > hey list, > > I have a custom Field implemented for one of my models.

Re: Translated URL's
Felipe,
Sorry, I'm quite busy these days.
Here is the beginning of something, but I'd prefer to avoid the 'myurl'
function. I'm not a dev' so you'll probably jump looking at that.
The base idea was to use only 'mypatterns' for obtainning the same
results we handwritten previously, including the ordering observation
you did. However, I cannot currently figure how to modify the url call,
that's why I had to use 'myurl'.
The following mess mostly butchered url and patterns functions normally
used.
It needs testing and that's quite raw but I'll take a look this week-end
probably. The don't think I handled 'prefix' variable how it should be
but that's for waiting ;)
