    text
    copied!<p>In my rails 3.2 app, I'm using <a href="https://github.com/rails/jbuilder">jbuilder</a> to render responses from my JSON api.</p> <p>I want to provide a common structure to all API responses, and a layout would be the likely solution to keep my views DRY.</p> <p>ex: I'd like every response to be of the following form :</p> <pre><code>{ status: "ok|error|redirect", data: { ... JSON specific to the current view ... }, errors: [ ... ], notes: [ ... ] } </code></pre> <p>(where the value for <strong>data</strong> is a json structure provided by the view, everything else is from the layout)</p> <p>However: I can't get the jbuilder layout yielding to the view correctly.</p> <pre><code># in layout json.data yield # in view json.some "value" </code></pre> <p>results in:</p> <pre><code>{"data":"{\"some\":\"value\"}"} # arg! my json has become a string </code></pre> <p>Trying things another way:</p> <pre><code># in layout yield # in view json.data do |json| json.some "value" end </code></pre> <p>results in :</p> <pre><code>{} </code></pre> <p>Has anyone had success doing this with jbuilder, or another json templating gem/method?</p> <p>This <a href="https://github.com/rails/jbuilder/issues/8">juilder github issue</a> suggests it's possible, but indicates others are having similar issues.</p> <p>I see rabl (https://github.com/nesquena/rabl/) is supposed to support layouts (https://github.com/nesquena/rabl/wiki/Using-Layouts), but I've decided not to use it for other reasons (rabl makes complex json structures a nightmare, particularly when trying to control object roots etc).</p>
