Pointing the form_tag to the Update Action of the Controller

Question

I have this in my view; I made the "new" and "edit" views similar with only the following snippet which dictates if the form is a patch or a post.

<% @selected_holiday[:id].present? ? (current_method = :patch) : (current_method = :post) %>
<%=
    form_tag( {method: current_method},
              class: 'create_form',
              id: "new_holiday_form",
              :"data-parsley-validate" => "" ) do
%>

My routes contains:

                  human_resources_settings_holidays GET      /human_resources/settings/holidays(.:format)                         human_resources/settings/holidays#index
                                                      POST     /human_resources/settings/holidays(.:format)                         human_resources/settings/holidays#create
                 new_human_resources_settings_holiday GET      /human_resources/settings/holidays/new(.:format)                     human_resources/settings/holidays#new
                edit_human_resources_settings_holiday GET      /human_resources/settings/holidays/:id/edit(.:format)                human_resources/settings/holidays#edit
                     human_resources_settings_holiday GET      /human_resources/settings/holidays/:id(.:format)                     human_resources/settings/holidays#show
                                                      PATCH    /human_resources/settings/holidays/:id(.:format)                     human_resources/settings/holidays#update
                                                      PUT      /human_resources/settings/holidays/:id(.:format)                     human_resources/settings/holidays#update

Yet from

http://localhost:3000/human_resources/settings/holidays/7d525fe6-b1e7-11e5-b6e8-00ff6a8ddd39/edit

I get:

http://localhost:3000/human_resources/settings/holidays/7d525fe6-b1e7-11e5-b6e8-00ff6a8ddd39/edit?method=patch

and therefore:

The action '7d525fe6-b1e7-11e5-b6e8-00ff6a8ddd39' could not be found for HumanResources::Settings::HolidaysController

How do I not hit the edit path and go through the PATCH?

Try

<% @selected_holiday[:id].present? ? (current_method = :patch) : (current_method = :post) %>
<%=
    form_tag(human_resources_settings_holiday_path, method: current_method,
              class: 'create_form',
              id: "new_holiday_form",
              :"data-parsley-validate" => "" ) do
%>

The first argument in your example make is a part of the URL params. You can also pass nil as the first argument if you want to specify current page as action

You probably want to switch the form action path accordingly as well

This might be a good time to refactor so that you don't have to do this checking at all. The rails form_for :resource helper allows you have pass in the resource, in this case @selected_holiday, and it will create the appropriate methods/actions.
