我正试图使用Flask和Flask SuperAdmin自定义我的Admin视图，然而，索引视图和子视图显然没有使用相同的is_accessible方法：
编辑：我设法弄清楚自己做错了什么。我需要在每个视图类中定义is_accessible。使用mixin类可以很好地实现这一点，如固定代码所示
app/frontend/admin.py（固定和工作代码）
from flask.ext.security import current_user, login_required
from flask.ext.superadmin import expose, AdminIndexView
from flask.ext.superadmin.model.base import ModelAdmin
from ..core import db
# all admin views should subclass AuthMixin
class AuthMixin(object):
def is_accessible(self):
if current_user.is_authenticated() and current_user.has_role('Admin'):
return True
return False
# the view that gets used for the admin home page
class AdminIndex(AuthMixin, AdminIndexView):
# use a custom template for the admin home page
@expose('/')
def index(self):
return self.render('admin/index.jade')
# base view for all other admin pages
class AdminBase(AuthMixin, ModelAdmin): # AuthMixin must come before ModelAdmin!
"""A base class for customizing admin views using our DB connection."""
session = db.session
# customize the form displays for User and Role models
class UserAdmin(AdminBase):
list_display = ('email',)
search_fields = ('email',)
exclude = ['password',]
#fields_order = ['email', 'active', 'last_login_at',]
class RoleAdmin(AdminBase):
field_args = {'name': {'label': 'Role Name'},
'description': {'description': "Duties & Responsibilities"}}
list_display = ('name', 'description')
然后使用我们的管理视图设置Flask应用程序：
apps/factory.py
app = Flask(package_name, instance_relative_config=True)
# other app setup stuff like db, mail, ...
from .frontend.admin import AdminIndex, UserAdmin, RoleAdmin
admin = Admin(app, name='PyCBM Admin',
index_view=AdminIndex(url='/admin', name='Admin Home'))
admin.register(User, UserAdmin)
admin.register(Role, RoleAdmin)
所以，正如标题所说，问题是：
/admin throws a 403 when an 'Admin' user isn't logged in, like it should, but
/admin/user lets anybody right on in.
我翻遍了源代码，试图找到另一个"全局所有管理蓝图"安全功能——也许我是盲人——但我找不到。
如果转到flask_superadmin/base.py，在第193行有以下代码片段：
def _handle_view(self, name, *args, **kwargs):
if not self.is_accessible():
return abort(403)
因此，这个方法可能必须被AdminIndex覆盖，以避免返回abort(403)，而是重定向到/login
