I'm getting an error message because of following statement
<!-- Else If Statement -->
<% elsif @student.user_id == current_user.id %>
Another User:
Show (Current User profile)

<% end %>
@student.user_id not working. But in DB id's are not empty and user_id also exists in student's table.
If I go like this
<% @students.each do |student| %>
<% elsif student.user_id == current_user.id %>
...
<%end %>
<% end %>
Intially everything woks fine. Current user able to edit, delete and show his profile and other user's able to show it only (i.e only show button appear). Else and Elsif statements works fine. But when another user add his data and after saving he's able to edit and delete current user' data.
Case 1: (Current user add his data)
Current User:
Show | Delete | Edit
Another User:
Show (Current User profile)
Case 2: (When another user enters his data and after saving it)
Current User:
Current User:
Show | Edit | Delete
Another User:
Show | Edit | Delete (Current User profile)
Another User:
Show | Edit | Delete (Current User profile)
