Render object directly

There are cases when you want to render object outside Rails view context. For instance to render objects in the console or to create message queue payloads. For these situations, you can use RablRails.render as show below:

RablRails.render(object, template, :view_path => 'app/views', :format => :json) #=> "{...}"

You can specify the format you want the object rendered (default to JSON) and also the view_path where views should be looked for (default is Rails default, 'app/views').

You can also passed locals in the options. You can define the object to render with the keyword object. For example, this will output exactly the same as the code above:

RablRails.render(nil, template, :view_path => 'app/views', :format => :json, :locals => { :object => object })

But locals are really useful when you're using instance variables in your templates. For instance, if you have the following template

object :@post
node(:read) { |p| p.read_by?(@user) }

you can set the @user instance variable in the locals options:

RablRails.render(post, template, :locals => { :user => user })

If you need to include view helpers or custom helpers, you'll need to include them in the rendering context

RablRails::Renderer::ViewContext.send(:include, Rails.application.routes.url_helpers)
