POrespond_to with custom format aliasing json format, is this possible?

Body
copied!<p>I have a situation where I'm returning json objects to my application which are built from YML files. Because to parse the yml file and return it as json I always have to do something like this:</p> <pre><code>format.json { render json: YAML.load(render_to_string :file => File.join(Rails.root,'app','views','home','icons.yml.erb'), :layout => false ) } </code></pre> <p>I would like to make this operation shorter, by creating a custom format that (however) result in a json, so I don't want to create a new mime type.</p> <p>My idea is to write:</p> <pre><code>format.myformat </code></pre> <p>Which will automatically search for <em>myaction.myformat.erb</em> inside views/mycontroller directory, and will automatically parse the yaml file returning it as a json object.</p> <p>Is this possible? If yes, how can I eventually do this?</p> <p><strong>Edit 1:</strong> I found an important suggestion in config/mime_types.rb:</p> <pre><code>Mime::Type.register_alias "text/html", :iphone </code></pre> <p>So I <strong>can</strong> alias a mime type, now the biggest problem is: how to define the default render action for a given format, like format.html does?</p> <p>If I write</p> <pre><code>format.html </code></pre> <p>current_action.html.erb will be automatically rendered, how can I choose the correct method to render a custom format?</p> <p><strong>Edit 2:</strong></p> <p>I managed to create this code (inside a controller, through some helper methods I built):</p> <pre><code> def icons respond_to do |format| format.extjson { render_to_extjson } end end </code></pre> <p>Is possible to make rails understand that if I write:</p> <pre><code> def icons respond_to do |format| format.extjson end end </code></pre> <p>it has to do:</p> <pre><code>format.extjson { render_to_extjson } </code></pre> <p>by default?</p>
