Question

I’m building a form to allow a user to CRUD a project permission.

….

<% roles = Role.all %>
<%= f.collection_select :role_id, roles, :id, :name, :prompt => true %>

Problems with the above, while it renders:

1. If a value matches, it shows that in the dropdown as selected, which is good. Problem, is if a user is set as ADMIN. It’s easy to use the dropdown to change the permission to something else, but not to CLEAR the permission…

Example… Select Drop Down:
– Please Select
– Admin
– Member
– Guest

If Admin is selected, Please Select never shows up…. How can I make an option show up to allow the user to remove the setting?

Any ideas? thx

I believe you want:

<%= f.collection_select(:role_id, roles, :id, :name, {:include_blank => 'Please Select'} %>
