"Like FileField, but validates that the uploaded object is a valid
image. Has two extra optional arguments, height_field and width_field,
which, if set, will be auto-populated with the height and width of the
image each time a model instance is saved."
So I made this model:
class Foto(models.Model):
# import os, os.path, Image
PhotoFile = models.ImageField(upload_to= PH_FOLDER + "/%Y/%m/%d/",
height_field="H", width_field="W")
titel = models.CharField(maxlength=80)
I tried to get the dimension of the imageobject in my template using
{{ object.W }}
{{ object.width }}
{{ object.width_field }}
Without succes. After adding the fields to the model I got an error
because I had to fill the fields. No auto population!!
How does this work?
