反向重定向不工作，但將數據插入到數據庫

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 

我得到以下

同樣只是一個新手

你傳遞kwargs到reverse作爲設置這個錯誤，什麼時候應該是字典：

kwargs={'pk': self.pk}
