I have a Projects View that shows a list of all projects… I want to
be able to say per project if the currently signed in user is a member
or not, and what there role is…
In the project View I have:
<% if team_member?(project.id, current_user) %>
then the helper:
module ProjectsHelper
def team_member?(project_id, current_user)
if
current_user.permissions.find_by_project_id(project_id).role.try(:name).nil?
true
else
false
end
end
end
*** But that errors. Can you help me out?
