Question

How can i display Rails error messages without brackets and quotes?

When a error message appears, it looks like:

["please fill out domain"]["please fill out email"]

How can i remove the brackets and the quotes?

Model

validates :domain,
          :presence => { :message => 'please fill out domain'},
          :uniqueness => { :message => 'domain already registered', :case_sensitive => true }
validates :email,
          :presence => { :message => 'please fill out email'},
          :uniqueness => { :message => 'email already registered', :case_sensitive => true }

Controller

I’m specify the url of the template (see format.html) cause i’m using a different controller

def create

  respond_to do |format|
    # save form data
    @login = Login.new(params[:login])

    # if validation fails, throw error messages
    if !@login.save
      flash[:error] = @login.errors.to_a if @login.invalid?
    end

    # render landingpage
    format.html { render :template => 'landingpage/index' }
    format.js { render :action => 'create' }

  end

end

create.js.erb

<% if @login.errors.any? %>
  // error

  var error_string = "";
  <% @login.errors.values.each do |msg| %>
    error_string += "<%= msg %>";
  <% end %>

  $("#flash_messages").html(error_string);

<% else %>
 // no error
<% end %>

View

<div id="flash_messages"></div>

When you iterate over the full error messages, you will already receive clean texts

In your create.js.erb, write the iteration as below:

@login.errors.full_messages.each do |msg|
