You can also implement policy-based security, conditionally allowing or disallowing access to parts of the
administrative interface. If a user does not have access to a particular view, the menu item won't be visible.
Generating URLs
---------------
Internally, view classes work on top of Flask blueprints, so you can use *url_for* with a dot
prefix to get the URL for a local view::
from flask import url_for
To redirect the user to another page if authentication fails, you will need to specify an *_handle_view* method::
class MyView(BaseView):
@expose('/')
def index(self)
# Get URL for the test view method
url = url_for('.test')
return self.render('index.html', url=url)
@expose('/test/')
def test(self):
return self.render('test.html')
If you want to generate a URL for a particular view method from outside, the following rules apply:
1. You can override the endpoint name by passing *endpoint* parameter to the view class constructor::
admin = Admin(app)
admin.add_view(MyView(endpoint='testadmin'))
In this case, you can generate links by concatenating the view method name with an endpoint::
url_for('testadmin.index')
2. If you don't override the endpoint name, the lower-case class name can be used for generating URLs, like in::
url_for('myview.index')
3. For model-based views the rules differ - the model class name should be used if an endpoint name is not provided. Model-based views will be explained in the next section.
