Question

I have an image model with an attribute :description which is a text, formatted as html text (e.g. with a few
in the text), which I display in a view as follows:

simple_format(@image.description)

raw(@image.description) will do mainly the same I think. How can I add a link_to helper with a link into that text? I’m searching for something like the following text (which will be @image.description):

Text text text text.

Text text #{link_to “Text”, @image.link)

@image.link will be the link. How can I do this?

Answer 1

Use ERB:

<%= raw ERB.new(@image.description).result(binding) %>

Wrap it in a helper method:

module ApplicationHelper
  def simple_format(content)
    ERB.new(content).result(binding).html_safe
  end
end

And use it like:

<%= simple_format(@image.description) %>

Some example content you could use for your image description could be:

Check out <%= link_to "the first image", image_path(1) %>!
