should this call the delete method on the model? Refmod.objects.filter(id__in=orphans).delete()

I overrode it, but it's not being called, I believe...

Is there a way to dump information posted by a form for understanding reasons

scrapcode: yes, i use pdb in the view to inspect

pp (pretty print) is very handy there

dir(form) is handy to see what methods are avail

jtri, thanks! I'll start there.

scrapcode: that combined with the doc usually helps make some headway

i'm trying to figure out why the delete method on a model (which i am over-riding) is not being called when this is run: Refmod.objects.filter(id__in=orphans).delete()

I haven't ran into a specific issue yet, but I'm about to tackle making my "Update Quanitites" functionality on a little shopping cart app I'm making. I'm going to make the whole cart a custom form and the text boxes be named with the "ShoppingCartItem" pk.

so I want to be able to see what data is being passed and how to reduce the headache of figuring it all out

I think I'll implement my idea and it'll be easier to ask for a code review to see if I should've designed it a bit different

I guess the docs confirm this does not call the delete method...

looks like pre-deldete signal might be the right thing, or perhaps looping over model instances and calling delete

I just noticed /admin is not available on my live site, but is available when I use runserver. Is this due to some configuration on my end? Or does django disable the admin site when DEBUG=False or something like that?

i'm using a 3rd party module for creating & sending mail; every time I create a new object (Mail.objects.create) i'd like to automatically schedule a background task for sending that mail. is there any way to decorate the Mail.objects.create function *every time* it's imported

my intuition is to just create a helper function somewhere in my main module which does this, but i'm not sure which standard django file to put this in

I have a shopping cart that has models User, Product, ShoppingCartItem. The "Cart" page lists the users "ShoppingCartItems" which have the quantity in the cart, etc. on the shopping cart view I have the quantity in a text box and want to update all the items at once when a button is clicked. How would I go about doing this with djangos form class?

It feels like something that would be structured around a ViewModel in ASP.NET... is doing something like that normal in Django?

I assume "formset" is the closest thing to being able to achieve what I want. But I'm not sure how to go about it.

Since I'm not really wanting to create empty forms...

should i use https://github.com/zacharyvoase/django-castor or https://github.com/dgilland/hashfs to spread my images from <django-project>/media/ to multiple directories? (got about 50,000 images and spreading them to multiple directories should increase load time)

hello) I create ModelForm auto during CreateView, it uses modelform_factory()... I would like to set clean() and clean_field_name() form methods to check some forms data... can I just monkeypatch form, which returns from modelform_factory()?

To describe what I'm trying to accomplish a bit better: https://stackoverflow.com/questions/44863524/up...

say i get passed a conn object that is the return value of psycopg2.connect(..) how can i have it print the actual url that im connecting too?

what is the difference between models.DateTimeField(default=timezone.now) and models.DateTimeField(auto_now_add=True) , FunkyBob ?

theology, maybe auto_now_add=True is safest way for default=timezone.now but i'm not sure, just guessing

Hello EveryOne.

ashish1500616: Hi!

hey :)

I want to know how to only use the attributes not having null values of an object in my template.

I am a developing a site of question papers for my university students.So I want to display only attributes having some picture(value) of the object a class.How to do this ? :- I am new to django.,Here is a link to my code:-http://dpaste.de/ZAzi

ashish1500616: well. you probably want an image model with fk to subject

ashish1500616: field_counter is almost always wrong

ashish1500616: but.. if obj.attribute

and btw, there's ImageField

src="/media/{{question_views.question_image_1 }}" that's also bad

there's question_image.file or url or somesuch

image.url actually

question_image.image.url actually, if it were an imagefield

nkuttler: Yes.,I am having Img files.what should I use in place of src="/media/{{question_views.question_image_1 }}"?

i guess file.url for now, with your FileFields..

I need to change FileField to ImageField.?

sounds like a good idea
