Hi,
i have a model (using newforms) where i have an image upload field.
Now i'm trying to check the image dimensions amongst other things.
I thought i could do this using validators.
It doesn't seem to call the validator specified in the model though.
How can i validate data?
def validate_image_size(field_data, all_data):
... validation code ...
class Icon(models.Model):
class Admin:
pass
name = models.CharField(maxlength=60, blank=False)
image = models.ImageField(upload_to="img/icons/", blank=True,
validator_list=[validate_image_size])
I then tried by making my own Image class and changing the ImageField in
the model
class Icon(models.Model):
...
image = LinksImageField(upload_to="img/icons/", blank=True)
class LinksImageField(models.ImageField):
def __init__(self, *args, **kwargs):
super(LinksImageField,self).__init__(*args, **kwargs)
but then i'm unsure what function to specify here to validate the data.
Thanks,
Benedict
