Create a templates.py file in your code and use this
"""This module provides a number of utility functions for use in templates."""
from pyramid.events import subscriberfrom pyramid.events import
BeforeRenderfrom pyramid.security import has_permission
@subscriber(BeforeRender)def add_global(event):
event['utils'] = TemplateUtils(event['request'])
class TemplateUtils(object):
def __init__(self, request):
self.request = request
def has_permission(self, permission):
return has_permission(permission, self.request.context, self.request)
def is_admin(self,user):
for role in user.role:
if 'Admin' in role.__dict__.values():
return True
return False
Now we can use these methods in templates as
%if utils.has_permission('admin'):
<li> <a href="/user/add"> Add user </a> </li>
<li> <a href="/users/list/vmusers"> User Configuration </a> </li>
<li> <a href="/users/list/admins"> Manage Admins </a> </li>
%endif
Correct me if i am wrong somewhere.
Thanks,
Regards,
