Instance Method Details

#set_layout(hash_or_layout) ⇒ Object

The set_layout method allows you to specify a number of methods and their layout. This allows you to use layout A for methods 1, 2 and 3 but layout B for method 4.

Examples:

# The key is the layout, the value an array of methods
set_layout 'default' => [:method_1], 'alternative' => [:method_2]

# We can combine this method with layout()
layout 'default'
set_layout 'alternative' => [:method_1]

# This is also perfectly fine
set_layout 'default'
