Question

Can any one help me in creating a drop down list in rails. I’m having a user table with a role field and I want to create a drop down list with values manager, investigator, director for role.How I can extract this value to parms[:role] . I’m new to rails.

Answer 1

If you are using form_for (not form_tag), then it should go like this.

<%= form_for @user do |f| %>
  ...
  <%= f.select :role, options_for_select(%w[manager investigator director]) %>

<% end %>

Then you’ll have params[:user][:role] available in your controller.
