在元素内保存到Rails数据库html

Question

I am trying to save the HTML within an element when I load the view. I found this documentation but I am new to RoR and I get the following error:

uninitialized constant HomeController::HTML

Here is my html

<div class="container_content">
  <h2>The element I want to save in my db</h2>
  <p>And this one too!</p>
</div>

The controller rendering the view with the html

class HomeController < ApplicationController
  def index
  end

  def show
    selector = HTML::Selector.new "div.container_content"
    Content.create html: selector, team_id: 1, last_update: Time.now
  end
end

Maybe I should try to select the html with javascript and find a way to send it to the database? I don't want to refresh the page in order to save the html.

Thanks for your help.

Answer 1

I'd put the html content in a partial then use ApplicationController.render or render_to_string

ie Something like

content = HomeController.render('path/to/partial')

or

content = render_to_string(partial: 'path/to/partial')
