Question

I have 3 url fields defined in my model as follows:

image_1 = models.URLField(max_length=100, verify_exists=True, blank=True)
image_2 = models.URLField(max_length=100, verify_exists=True, blank=True)
image_3 = models.URLField(max_length=100, verify_exists=True, blank=True)

My question is, is there a way I can test whether the verify_exists returns True or False and if so take action depending on the output?

What django does is it use’s the URLValidator to see if the url is valid or not.
what you could is use the same validations which is present in django.core

EDIT:
For example lets say you have to validate if django official website with url https://www.djangoproject.com/, exists or not. the code would simply look like this:

from django.core.validators import URLValidator
from django.core.exceptions import ValidationError


my_url_validator = URLValidator(verify_exists=True) #creates a URLValidator object with verify_exists.
my_url = "https://www.djangoproject.com/" #url to be verified   

#check if url is valid :)
try:                           
   my_url_validator(my_url) 
except ValidationError:
   #not valid!! :_( 
   #fix: custom stuff to the rescue :)     
   CustomStuff()...
