class Post(models.Model):
category = models.ForeignKey(Category, on_delete=models.CASCADE)
title = models.CharField(max_length=200, unique=True)
slug = models.SlugField(max_length=200, unique=True)
featured_image = models.ImageField(null=True, blank=True, upload_to="blog/", verbose_name='Featured Image')
author = models.ForeignKey(User, on_delete= models.CASCADE,related_name='blog_posts')
updated_on = models.DateTimeField(auto_now= True)
content = RichTextUploadingField()
created_on = models.DateTimeField(auto_now_add=True)
status = models.IntegerField(choices=STATUS, default=0)
class Meta:
ordering = ['-created_on', 'title']
def __str__(self):
return self.title
def _generate_slug(self):
value = self.title
slug_candidate = slugify(value, allow_unicode=True)
self.slug = slug_candidate
def save(self, *args, **kwargs):
if not self.pk:
self._generate_slug()
super().save(*args, **kwargs)
my admin.py
class PostAdmin(admin.ModelAdmin):
list_display = ('title', 'slug', 'status', 'category', 'author','created_on')
list_filter = ("status",)
search_fields = ['title', 'content']
prepopulated_fields = {'slug': ('title',)}
actions = [export_as_csv_action("CSV Export", fields=['title','slug','author','featured_image','status','created_on','updated_on'])]
