Reverse redirect does not work but inserts data into db
Question: 
    from django.db import models
    from django.core.urlresolvers import reverse
    
    
    class Gallery(models.Model):
        Title = models.CharField(max_length=250)
        Category = models.CharField(max_length=250)
        Gallery_logo = models.CharField(max_length=1000)
    
        def get_absolute_url(self):
            return reverse('photos:detail', kwargs={'pk', self.pk})
    
        def __str__(self):
            return self.Title + '_' + self.Gallery_logo
    
    
    class Picture (models.Model):
        Gallery = models.ForeignKey(Gallery, on_delete=models.CASCADE)
        Title = models.CharField(max_length=250)
        Artist = models.CharField(max_length=250)
        Price = models.CharField(max_length=20)
        interested = models.BooleanField(default=False)
    
        def __str__(self):
            return self.Title
    

Am getting this error below

Again am just a newbie


Answer: You're passing `kwargs` to `reverse` as a _set_ , when it should be a
dictionary:

    
    
    kwargs={'pk': self.pk}
    #           ^
