Ruby On Rails - Reusing the error message partial view -

problem

i trying reuse error message block in views.

below block written in positions/_error_messages.html.erb

<% if @position.errors.any? %>   <div id="error_explanation">    <div class="alert alert-error">      form contains <%= pluralize(@position.errors.count, "error") %>.    </div>    <ul>     <% @position.errors.full_messages.each |msg| %>     <li>* <%= msg %></li>    <% end %>    </ul>  </div> <% end %> 

the problem have created similar partial view in every model kind of repeating same code different object i.e. @user, @client etc.

remedy

i have created 1 erb in shared folder shared/_error_messages.html.erb , wrote below code.

<% def error_message(active_object) %>  <% if active_object.errors.any? %>   <div id="error_explanation">    <div class="alert alert-error">     form contains <%= pluralize(active_object.errors.count, "error") %>.    </div>    <ul>     <% active_object.errors.full_messages.each |msg| %>      <li>* <%= msg %></li>     <% end %>    </ul>   </div>  <% end %> <% end %> 

and in view file. positions/new.html.erb wrote below code

<div id="errorbox">   <%= render "shared/error_messages" %>  <%= error_message(@position) %> </div> 

it means can use same code in create , update operations.

i want know, correct way it? or there other option?

no, defining methods in views not correct way it. think should rather substitute @position first partial local variable named in more generic way, example object , render partial with:

<%= render 'shared/error_messages', object: @position %> 

which passes @position local variable object partial.
