Question

我正在尝试创建两个行为不同的管理页面。我已经成功地制作了两个单独的管理页面，但我似乎无法弄清楚如何为第二个管理页面设置AdminIndexView。

class FlaskAdminIndexView(AdminIndexView):
    @expose('/')
    def index(self):
        if not current_user.is_authenticated:
            return redirect(url_for('security.login'))
        elif (current_user.is_authenticated) and (not current_user.has_role('first_admin')):
            return redirect(url_for('post_user.index_entry'))
        else:
            return super(FlaskAdminIndexView, self).index()

first_admin = flask_admin.Admin(app, 'RCIGM ADMIN', base_template='my_master.html', 
                          template_mode='bootstrap3',
                          index_view=FlaskAdminIndexView())

以上代码段是我将用户辅助功能设置为第一个管理页面的方式。

class FlaskSecondAdminIndexView(AdminIndexView):
    @expose('/')
    def index(self):
        if not current_user.is_authenticated:
            return redirect(url_for('security.login'))
        elif (current_user.is_authenticated) and (not current_user.has_role('second_admin')):
            return redirect(url_for('post_user.index_entry'))
        else:
            return self.render('admin/base.html')
            #return super(FlaskAdminIndexView, self).index()

second_admin = flask_admin.Admin(app, 'SITE ADMIN', url='/site_admin', 
                           base_template='my_master.html', endpoint='site_admin',
                           template_mode='bootstrap3', index_view=FlaskSecondAdminIndexView())

上面的代码片段是我的第二个管理页面，我得到的蓝图冲突错误如下所示。

非常感谢任何帮助或建议！

创建url时，您需要传递endpoint和AdminIndexView。

例如：

from flask import Flask
from flask_admin import Admin, expose, AdminIndexView


app = Flask(__name__)


@app.route('/')
def index():
    return '''
        <a href="/first-admin/">Click me to get to First Admin!</a><br>
        <a href="/second-admin/">Click me to get to Second Admin!</a>
        '''


class FirstAdminIndexView(AdminIndexView):
    @expose('/')
    def index(self):
        return 'Hello From first admin :{}.'.format(self)


class SecondAdminIndexView(AdminIndexView):
    @expose('/')
    def index(self):
        return 'Hello From second admin :{}'.format(self)


first_admin = Admin(
    app,
    template_mode="bootstrap3",
    url='/first-admin',
    endpoint='first',
    index_view=FirstAdminIndexView(url='/first-admin', endpoint='first')
)


second_admin = Admin(
    app,
    template_mode="bootstrap3",
    url='/second-admin',
    endpoint='second',
    index_view=SecondAdminIndexView(url='/second-admin', endpoint='second')
)


if __name__ == '__main__':
    app.run(port=5000, debug=True)
