Question

I installed the ckeditor gem:

https://github.com/galetahub/ckeditor

I followed all the steps and I’m displaying it like this:

<%= form_for(@post) do |f| %>
  <%= render 'shared/error_messages' %>
  <div class="field">
    <%= f.label :title %><br />
    <%= f.text_field :title %>
  </div>
  <div class="field">
    <%= f.label :content %><br />
    <%= f.cktext_area :content, :input_html => { :value => "Default value" } %>
  </div>
  <div class="field">
    <%= f.label :tag_name %>
    <%= f.autocomplete_field :tag_name, autocomplete_tag_name_posts_path, :"data-delimiter" => ' ' %>
  </div>
  <div class="actions">
    <%= f.submit %>
  </div>
<% end %>

and this is how I show the content:

<p><%= @post.content %></p><br />

But the output are the actual HTML tags. For instance:

<p> Default v<strong>al</strong>ue s<u>ada</u>sd</p>

How can I make it so that it actually renders the final HTML?

Answer 1

Rails escapes the output by default so you have to use raw:

<p><%= raw @post.content %></p>

Be careful using raw though, it’ll open you up to XSS attacks if you’re allowing untrusted users to output HTML on your site.
