Rails Disable devise flash messages

Solution 1:

Probably the easiest way to do this is to

1. Define each message as a blank string
2. Check the length of the string before you show a flash message.

In your devise.en.yml file, specify each message as empty:

en:
  errors:
    messages:
      not_found: ''
      already_confirmed: ''
      not_locked: ''

etc. Next, in your layout, check for blank flash strings before you output them.

<% flash.each do |key, value| %>
  <%= content_tag :div, value, :class => "flash #{key}" unless value.blank? %>
<% end %>

Solution 2:

An answer better suited for me was to override the Devise Session Controller like this

class SessionsController < Devise::SessionsController

  # POST /resource/sign_in
  def create
    super
    flash.delete(:notice)
  end

  # DELETE /resource/sign_out
  def destroy
    super
    flash.delete(:notice)
  end

end

This safely overrides the create and destroy method removing the flash message
