Rails: How to determine controller/action in view

This is my form partial:

<%= f.simple_fields_for :photo_attributes, :html => { :multipart => true } do |d| %>
    <%= d.label :image, :label => 'Upload logo', :required => false  %>
    <%= d.file_field :image, :label => 'Image, :required => false', :style => 'margin-bottom:2px'  %>
    <%= d.input :image_url, :label => 'Billed URL', :required => false %>
<% end %>

If the action is edit I want to show this instead:

<%= f.simple_fields_for :photo, :html => { :multipart => true } do |d| %>
    <%= d.label :image, :label => 'Upload logo', :required => false  %>
    <%= d.file_field :image, :label => 'Image, :required => false', :style => 'margin-bottom:2px'  %>
    <%= d.input :image_url, :label => 'Billed URL', :required => false %>
<% end %>

How can i achieve this?

Rails 5: Display Action within the view

<%= action_name %>

If statement within the view

<% if action_name == "edit" %>
  This is an edit action.
<% end %>

current_page?(action: 'edit')

See ActionView::Helpers::UrlHelper#current_page?

Rails also makes the methods controller_path, controller_name, action_name available for use in the view.

Just use @_controller.action_name in view

You could write something like

<%- form_url = @object.new_record? ? :photo_attributes : :photo %>
<% f.simple_fields_for form_url, :html => { :multipart => true } do |d| %>

That is, if you have an @object to check against. Otherwise you could use action_name (and even controller_name).

So something like:

<%- form_url = action_name == :edit ? :photo : :photo_attributes %>
<% f.simple_fields_for form_url, :html => { :multipart => true } do |d| %>

Hope this helps.

Generally the form partial only contains the fields, not the form tag or the fields for, but if you have no other way, you can always see what params[:action] is currently set to and behave accordingly.
