rails 4 — flash notice

Question

I\'m still working on my rails 4 demo site, and I\'m seeing an odd thing. In the controller it has a line like this:

format.html { redirect_to @widget, notic         


        

Answer 1

In application.html.erb, you would be displaying the flash messages.

Update that code as below

  <% flash.each do |name, msg| %>
    <%= content_tag :div, msg, class: "alert alert-info" %>
  <% end %>

You can add the classes that you want to apply to the flash message in the class option.

EDIT

The class is setup as alert alert-notice because of alert alert-<%= key %> in your code. When you call redirect_to @widget, notice: 'Widget was successfully created.

A flash message would be added in flash hash with key as notice and value as Widget was successfully created., i.e.,

flash[:notice] = "Widget was successfully created."

EDIT #2

format.html { redirect_to @widget, notice: 'Widget was successfully created.' }

notice: 'Widget was successfully created.' is an argument passed to redirect_to method. It is added to flash hash in this method.
