ruby on rails - Retrieving contact details from contact id using collection select -

i utilize next collection select allow users pick contact name.

<div class="form-group"> <%= f.label :contact %> <%= f.collection_select(:contact, current_user.contacts.all, :id, :name, prompt: true, class: "form-control") %> </div>

but, instead of name, it's id that's displayed when utilize email.contact in show page. have tried using email.contact.name , returns nomethoderror. associations, email has_many contacts , contacts belongs_to email. tried using inverse_of these association, still unable retrieve contact name. there workaround solve this?

if @ collection_select

collection_select(object, method, collection, value_method, text_method, options = {}, html_options = {})

if @ docs says

the :value_method , :text_method parameters methods called on each fellow member of collection. homecoming values used value attribute , contents of each tag, respectively.

so need pass value_method method want save in db, right using id. save name can this:

<%= f.collection_select(:contact, current_user.contacts.all, :name, :name, prompt: true, class: "form-control") %>
