flask_login的多个用户

Question

我有两个用于flask_login的用户模型：

class Admin(db.Model, UserMixin):
    id = db.Column(db.Integer, primary_key=True)
    name = db.Column(db.String(30))
    password_hash = db.Column(db.String(200))

class Merchant(db.Model, UserMixin):
    id = db.Column(db.Integer, primary_key=True)
    name = db.Column(db.String(30))
    password_hash = db.Column(db.String(200))

现在我想在会话中加载用户：

@login_manager.user_loader
def load_user(user_id):
    pass

我想知道如何从两个模型加载用户。

Answer 1

#You can create a permission 
admin_permission = Permission(RoleNeed('admin'))

#protect a view with a principal for that need
@app.route('/admin')
@admin_permission.required()
def do_admin_index():
     return Response('Only if you are an admin)
