Type of instance fields is FileField instead of ImageField about sorl-thumbnail HOT 9 CLOSED

I didn't mean that the type shows as a Django ImageField.

I meant that it shows as a Django FIleField rather than a sorl ImageField as I would have expected.

Sorry this the FieldFile, its bit complicated, read django source... :/

Sorry. I don't understand your last comment.

By my understanding if I import a type and create an instance of it then type(object) should return that type.

I'm trying to introspect and access the extra methods of sorl's ImageField but dir(my_field) doesn't show anything other than the base FileField properties and methods.

>>> from sorl.thumbnail import ImageField
>>> type(ImageField())
<class 'sorl.thumbnail.fields.ImageField'>

How about type on an instance of ImageField as in my original report. Do you get a different result to me?

from sorl-thumbnail.

Whats the actual issue here? Yes I get the output as above (which is on the instance).

from sorl-thumbnail.

from sorl.thumbnail import ImageField

def MyModel(models.Model):
    image = ImageField(upload_to='path/to')

foo = MyModel()

I do:

type(foo.image)

and get:

<class 'django.db.models.fields.files.FieldFile'>

instead of expected:

<class 'sorl.thumbnail.fields.ImageField'>

If this doesn't happen for you then I'll take another look at my setup as it's obviously just me. :)

This case is due to the way django works using descriptors, its not a sorl thumbnail issue, have a look in django source code.

Ah. I get it now. Doh!
