can I find out in a field's clean method if the value of the field has been modified (supposing model form and and edit action).

?

something like this could work? https://dpaste.de/DnWO

clime: you're defining a custom field class inside the form??

seems so

morning, ChrisMorgan

I’m finding it hard to get any decent answers on the topic from the documentation or elsewhere; CharField and TextField and the likes: are they going to be (Py2K terminology) unicode objects? Or does it depend on the database encoding?

Hello, why when use this in my view not work: context['galleries'] = Product.images.all()[:4] return this error: 'ForeignRelatedObjectsDescriptor' object has no attribute 'all'

ChrisMorgan: unicode

Regardless of database encoding or collation?

(Ignoring the MySQLdb issues.)

why when use this in my view not work: context['galleries'] = Product.images.all()[:4] return this error: 'ForeignRelatedObjectsDescriptor' object has no attribute 'all'

DevePy: You'd need to have an individual product to get its images.

mattmcc: Yes, i'm use: item = Product.objects.get(pk = 1)

Then you want item.images.all()[:4]

yes, this is a example

i'm work nivel view CBV, DetailView

DetailView, return one object

mattmcc: If use self.object.images.all() work 100% http://stackoverflow.com/questions/23353474/for...

hello. Looking for apps. 1) "login with facebook" 2) scheduling thing, like "every 2 days, but only monday through friday" etc

DevePy: Yes, you need to have a product instance to use .images.all()

Product.images.all() doesn't make sense, because images are related to a specific product.

Unless you wanted to just fetch all images, in which case you'd be doing Image.objects.all()

mattmcc:I think this works well in Django 1.5
