python - Flask Principal granular resource on demand -

i've been looking @ post: http://pythonhosted.org/flask-principal/#granular-resource-protection

now while there nothing wrong how working can't see usable since @ time of login posts read , editblogpostneed added identity.

imagine if have been writing more normal number of posts long term not strategy check post access view /posts/<post_id>.

is there way check on each request view using flask principal?

i can of course around lazy relationship query , filter want use flask principal.

not sure understand question entirely, might help. in flask app, i'm using flask-principal role permission such admin , editor, , i'm using granular resource protection described in flask-principal docs. in case i'm checking if user has permission access particular account. in each view identity loaded , permission checked.

in view:

@login_required def call_list(id, page=1):      dept = models.department.query.get_or_404(id)     view_permission = auth.viewaccountpermission(dept.office.account_id)      if view_permission.can():         # 

the custom permission:

viewaccount = namedtuple('view', ['method', 'value']) viewaccountneed = partial(viewaccount, 'view')  class viewaccountpermission(permission):     def __init__(self, account_id):         need = viewaccountneed(unicode(account_id))         super(viewaccountpermission, self).__init__(need) 

and in identity loader function:

if hasattr(current_user, 'assigned_accounts'):     account_id in current_user.assigned_accounts():         identity.provides.add(auth.viewaccountneed(unicode(account_id)))
