ruby on rails - How to use same Partial for multiple resources? -

i'm using tables list recorded database in index templates, , usual last 3 table cells used links of show, edit , destroy object.

../users/index.html.erb

<table>   ...     <% @users.each |user| %>       <tr>         ...         <td><%= link_to 'show', user %></td>         <td><%= link_to 'edit', edit_user_path(user) %></td>         <td><%= link_to 'destroy', user, method: :delete, data: { confirm: 'are sure?' } %></td>       </tr>     <% end %>   </tbody> </table> 

anyway, trying replace links text bootstrap's glyph icons, , succeeded got messy thought better put in partial variable shared index templates use same table layout.

../shared/_editlinks.html.erb

<td>   <%= link_to dist %>     <span class="glyphicon glyphicon-eye-open"></span>   <% end %> </td> <td>   <%= link_to send("edit_#{dist}_path(#{dist})") %>     <span class="glyphicon glyphicon-edit"></span>   <% end %> </td> <td>   <%= link_to dist, method: :delete, data: { confirm: 'are sure?' } %>     <span class="glyphicon glyphicon-remove"></span>   <% end %> </td> 

then use following code line render partial in index table. passing resource name variable.

 <%= render 'editlinks', dist: user %> 

then first , last links seems work fine got error around middle -edit- link.

undefined method `edit_user_path(#<user:0x007f611ab015a8>)' #<#<class:0x007f611a7064d0>:0x007f611ab143b0> 

can tell me causes error , how work?

the lines causing errors because you're trying treat object string.

because _path helpers typically snake_case, can use underscore method on object's class name so:

<%= link_to send("edit_#{dist.class.name.underscore}_path", dist) %> 

as pointed out deepak, can providing dist object second argument send. otherwise, you'll end similar error because you'd again treating object value can coerced string.
