from django.db import models  
from django.urls import reverse  
from django.contrib.auth.models import User  
  
  
class Movies(models.Model):  
  
   user = models.ForeignKey(User, on_delete=models.CASCADE)  
   title = models.CharField(max_length=200)  
   genre = models.CharField(max_length=200)  
  
   def __unicode__(self):  
     return self.title  
  
   def get_absolute_url(self):  
     return reverse('CRUD_FBVs:movies_edit', kwargs={'pk': self.pk})

class MoviesForm(forms.ModelForm):  
   
     class Meta:  
         model = Movies  
         fields = ['title', 'genre']
