Partials

Codecabulary Home / Learn Rails / Partials

Partials are reusable snippets of Rails view code, meaning you can use them to DRY it out.

Install the Rails Partials Package for Sublime Text 2

1. Press command shift P

2. Select Install Package

3. Select Rails Partials

Create a Partial

1. Highlight a snippet you want to reuse

2. Press alt P

3. Name the partial

4. Sublime will add the leading underscore and filetype (.html.erb) that denotes a partial

5. If you create a partial in the layout file, it must go in app/views/application. If the folder doesn't exist, you'll likely have to move it yourself.

6. Render the partial (Sublime will also do this for you):

   <%= render "partial_name" %>

Changing Loops to Partials

1. Take your standard each loop:

   @events.each do |event|
   	<td><%= event.name %></td>
   	<td><%= event.location %></td>
   end

2. Remove the do/end lines:

   <td><%= event.name %></td>
   <td><%= event.location %></td>

3. Make it a partial (Alt P, name it). In this case, I named it "event."

4. Change the render line to a hash including the collection option:

   <%= render partial: "event", collection: @events %>
