Print valid, non-escaped JSON in a view with Rails

Question

I\'ve tried everything. Every combination of the helpers raw, html_safe to_json including some attempts with ::JSON.encode

Answer 1

Since ActiveSupport 2.3.3 you have been able to do .as_json

Answer 2

Try this with utility method

var campaignData<%=h " =#{raw @campaign.to_json}" if @campaign %>;

Answer 3

Did you try escape_javascript?

Here is an example from the *.haml file, which I just added to test my answer.

:javascript
  var foo=$.parseJSON("#{j @albums.to_json}")

Where j is an short alias for escape_javascript.

Answer 4

The problem here is with the "=" string. As it's considered unsafe, it taints the other string.

You can probably do either:

raw("=" + @campaign.to_json)

or

"= #{@campaign.to_json}".html_safe

which are roughly the same.
