Writing Inline partials in Rails

Author photoRico Sta. CruzFebruary 18, 2015

Ever find it difficult to have really long blocks of code in a Rails view?

- if @list.any?
  - @list.each do |item|
    - # really long code
    - # ...

- else
  - # also long code
  - # ...

These blocks can be separated into partials. Alternatively, Proc.new can be used to define them inline in one file.

- body, list, empty = nil
- body = Proc.new do
  - if @list.any?
    - list.call
  - else
    - empty.call
-# List of items
- list = Proc.new do
  %div
    - @venues.each do |venue|
      = venue
-# No items available
- empty = Proc.new do
  %div nothing here

- body.call
