Why does Ckeditor work weird?

Question

Ruby on Rails

I connect in ruby ​​on rails ckeditor.
1) I include js - //= require ckeditor/init
2) I write a helper - <%= cktext_area :content, value: 'Default value', id: 'sometext' %>
The result is this:

The source code looks like this

: as if the tags are not inserted correctly, break off and everything breaks in the end. What to do with it?

Answer 1

Because the first 2 parameters are object_name, method or use on form_builder only with the method
Source code one and two , as your own and in other helpers in rails text_field for example So
you have two options:
or

<%= form_for @object do |form| %>
  <%= form.cktext_area :content %>
<% end %>
