在django中基于模型字段名称创建权限

from django.db import models
from django.contrib.auth.models import Permission

class Book(models.Model):
    title = models.CharField(max_length=100)
    author = models.CharField(max_length=100)

# 创建权限
title_permission = Permission.objects.create(
    codename='can_view_title',
    name='Can view title',
    content_type=ContentType.objects.get_for_model(Book),
)

author_permission = Permission.objects.create(
    codename='can_view_author',
    name='Can view author',
    content_type=ContentType.objects.get_for_model(Book),
)

user.user_permissions.add(title_permission)
