# Returns the contents that are yielded to a layout, given a name or a block.
|
|
#
|
|
# You can think of a layout as a method that is called with a block. If the user calls
|
|
# <tt>yield :some_name</tt>, the block, by default, returns <tt>content_for(:some_name)</tt>.
|
|
# If the user calls simply +yield+, the default block returns <tt>content_for(:layout)</tt>.
|
|
#
|
|
# The user can override this default by passing a block to the layout:
|
|
#
|
|
# # The template
|
|
# <%= render :layout => "my_layout" do %>
|
|
# Content
|
|
# <% end %>
|
|
#
|
|
# # The layout
|
|
# <html>
|
|
# <%= yield %>
|
|
# </html>
|
|
#
|
|
# In this case, instead of the default block, which would return <tt>content_for(:layout)</tt>,
|
|
# this method returns the block that was passed in to <tt>render :layout</tt>, and the response
|
|
# would be
|
|
#
|
|
# <html>
|
|
# Content
|
|
# </html>
|
|
#
|
|
# Finally, the block can take block arguments, which can be passed in by +yield+:
|
|
#
|
|
# # The template
|
|
# <%= render :layout => "my_layout" do |customer| %>
|
|
# Hello <%= customer.name %>
|
|
# <% end %>
|
|
#
|
|
# # The layout
|
|
# <html>
|
|
# <%= yield Struct.new(:name).new("David") %>
|
|
# </html>
|
|
#
|
|
# In this case, the layout would receive the block passed into <tt>render :layout</tt>,
|
|
# and the struct specified would be passed into the block as an argument. The result
|
|
# would be
|
|
#
|
|
# <html>
|
|
# Hello David
|
|
# </html>
