Answer 1

I have not used tinymce , but as per documentation what I understand is

If you want to add content to editor pass that to the text area

<%= text_area_tag :editor, @page.content , :class => "tinymce", :rows => 40, :cols => 120 %>

# you can pass configuration option to tinymce here
<%= tinymce %>

In Show page

<p>
<%= @page.content.html_safe %> #Apply html_safe function to interpret string as html
</p>

This works for me.
