Executing validation on entry to class-based views

Greetings, I have an app with a CBV for the main functionality that I'd like to do some validation on config settings (in settings.py) before carrying out the view. My particular view in this case is a FormWizard, but I'd like to know general to any CBV; what is the correct pattern for doing this

How to do 2-ModelForm-in-1-CVB right?

Hi, I am trying to handle 2 ModelForm in 1 view. Is that possible with CBV solution? Does any best practise exist? Here is the problem in details. ## models.py class UserProfile(HasJPAddresses, models.Model): user = models.OneToOneField(User) birthdate = models.DateField(default='1900

Re: Recommended dev environment for a Django project deployed to Linode

Yes, I like to have three levels, too. I call the middle one "staging". You can tear it down and build it up again as many times as needed to get it right. A ten-year-old PC will work fine for staging practice. Blow the dust out (the dust affects cooling and leads to poor reliability), load Ubunt

Re: Recommended dev environment for a Django project deployed to Linode

I guess that it's what you're used to. I'm perfectly happy with emacs (less so with vi or vim, but still happy enough). I'm happy with emac's python mode, css mode, etc. There's even supposed to be help for Django templates now. I'm using the Espresso add-on for JavaScript. It's not everything

Re: Not able to create an simple application using DB (syncdb error)

And where is your settings.py file? If it is in the same directory as manage.py, and it is a reasonably current Django (1.4, 1.5), then it's in the wrong place. It belongs in a sub-directory named 'blog1', along with your urls.py, wsgi.py and an empty __init__.py . On Wed, Sep 25, 2013 at 1:40

IntegrityError with proxy model but not with parent?

I am working with a proxy model that does not seem to work with the 'unique_together' of the model being proxied. What I have is: class Parent(Model): id = AutoField(primary_key=True) name = CharField() stuff = CharField() class Meta: ordering = ['name'] unique_to

Fine. I don't think my boss is going to pay for PyCharm license, so I'll probably go for Eclipse now (I don't really like it too much, but if works, it's ok for me) About virtualenv, is there any method to provide something like a script to create a virtualenv, install the needed software and h

Hello, First of all, many thanks for your response. Sorry for the delay answering this. I was in a business trip. So, you basically have 2 environments: your own machine, and the Linode box. You make the development and testing in your machine, and Linode is for production purposes. And you c

I assumed the OP wanted to get *all* instances of Item even if they don't have any liked status equals to 'L'. The query you provided will filter out instances of Item with `itemlikestatus__count < 1` instead of returning an annotated value of 0. Le mercredi 25 septembre 2013 04:41:37 UTC-4, Da

Server-side validation for complex ajax forms

Hi all, I have been asked to build a single-page, ajax based data entry interface for a moderately complex set of models. There are 5 models, linked into a tree structure by foreign keys. The number of children for each model is variable, so there could be up to 4 levels of nested formsets. I can
