how to create a array of hashes in Rails 4?

Question

I am trying to make this behavior with my custom toastr notification

this is what i have

  def toast(type, text)
   flash[:toastr] = { type => text }
  end

I call this in my controller like this

toast('success',"this is a message")

and it would output to my template like so

        <% flash[:toastr].each do |type, message| %>
            toastr.<%= type %>('<%= message %>')
        <% end %>

however it only outputs 1 message

now here is the functionality I am trying to make, which is display multiple flash messages http://tomdallimore.com/blog/extending-flash-message-functionality-in-rails/

it works because of the following method

def flash_message type, text
  flash[type] ||= []
  flash[type] << text
end

everytime you call #flash_message, it would save the flash message in an array, and I can use for each on the array to display it.

I am having trouble converting my #toast into that, #toast CURRENTLY does this

flash[:toastr] = {'success' => "this is a message"}

I would like to do this

flash[:toastr] = [{'success' => "this is a message'},{'error' => "problem!"}]

Can someone help me modify toast method to accept an array of hashes, and inserts a new hash everytime its called?

def toast type, text
  flash[:toastr] ||= []
  flash[:toastr].push({ type => text })
end

Using append (<<):

def toast type, text
  flash[:toastr] ||= []
  flash[:toastr] << { type => text }
end
