Re: Model Formsets.save(commit=False) behaviour

I've used that a lot and never had a problem. I'd recommend stepping through the code. When you call save, you go into the save() function in django/forms/models.py, which immediatey takes you into the save_Instance() method. That code is quite straight forward. At the bottom it just looks at

Hi Margie, I'm not sure off the top of my head, but if memory serves me right, template tags may not allow variable number of parameters. I'd take a look at the code from the {% url %} template tag, it's syntax allows for multiple variables, but they're passed in a very particular way. It's actu

I want to write a templatetag that goes through a bunch of media and returns the media lines without duplicates, something like this (except I'm not removing duplicates here, not sure if the '+' is going do it for me or not). def form_media(*args): finalFormMedia = Media() for formMedia i

Model Formsets.save(commit=False) behaviour

Hi all, I'm trying to use the .save(commit=False) method on a model formset in my view but for some strange reason, the django code executes the model's save method. My understanding of the docs is that when (commit=False) is passed - the formset will return a list of model instances but not com

I thought that might be the case. Is that true of the deletes done by a formset save as well? IE, when a formset.save() is done, in some cases my delete will be called, and in some cases not? Margie On May 9, 4:57 pm, James Bennett wrote: > On Sat, May 9, 2009 at 7:49 PM, George Song wrote:

If you can see it properly in the django server but not in apache, and you see poor text instead of layout, my guess is apache can't access or find your MEDIA_URL location (check symlink or file permissions), so it does not load your images and css. also, check your apache2/access.log xau On May
