django 1.7+ default_permissions
由于做Caption要做权限设计。在核心类的设计的时候需要做好权限的基础设计。django 1.7+以后 django.db.modes新增特性 default_permissions,官方文档语焉不详。
决定自己探索下,不想一一分析代码,遂引入bug,直接观察核心线路。
引入bug方法:
class baseModel(models.Model): #.... class Meta: default_permissions=‘add‘#should be (‘add‘,‘change‘,...)
错误如下:

直接在最终的文件C:\Python27\lib\site-packages\django-1.7.2-py2.7.egg\django\db\backends\sqlite3\base.py里面加入print xxx之类的语句。如下:
def execute(self, query, params=None): if params is None: return Database.Cursor.execute(self, query) query = self.convert_query(query) print query,params#在这里添加了print return Database.Cursor.execute(self, query, params)
再次migrate,并观察sql:
