hi!
i have a little problem, im working with permissions, so if u are a
normal user, u can only view something and admins can view,edit, delete
i pick up the level, and then i check up, if the level is right, and
then i put the options. but i dont know why, the admin can only view and
delete, i mean my code only take the last link_to
here is the code:
<%= link_to "read", :action => "show", :id =>
message.send(''id'') %>
<%= if @level == 2
link_to "edit", :action => "edit", :id =>
message.send(''id'')
elsif @level == 3
#HERE IS THE PROBLEM, I BECOME ONLY THE LINK TO DESTROY, AND NOT
BOTH.
link_to "edit", :action => "edit", :id =>
message.send(''id'')
link_to "destroy", :action => "destroy", :id =>
message.send(''id'')
end
%>
ty!!

pipogol wrote:> help please, im trying everything and nothing...it''s a little hard to understand from what you''ve written above(and how is @level defined?), but on a very first glance, <%= if ...blah %> isn''t a correct syntax. instead of doing <%= if a elsif b else c %> do <% if %><%= a %> <% elsif %><%= b %> <% else %><%= c %> <% end %> helps? -- Posted via http://www.ruby-forum.com/.

The if expression returns the last thing it evaluates, which is then printed by the code which handles the <%=. So, why does link_to "edit" not get printed out? Becaause it''s return value is never used, as you go on to evaluate the link_to "destroy", the result of which is passed to <%= and printed. hth, Douglas
