Instance Attribute Details

#output_buffer ⇒ Object

<%= render “nice_partial” do |p| %>

  <% p.content_for :title, "Yo" %>
  This content can be accessed through calling `yield`.
<% end %>

Then in the nice_partial:

<%= content.content_for :title %> # => "Yo"
<%= content.output_buffer %> # => "This line is printed to the `output_buffer`."

# File 'lib/nice_partials/partial.rb', line 53

def capture(*arguments, &block)
  self.output_buffer = @view_context.capture(*arguments, self, &block)
end

#content_for(name, content = nil, *arguments, &block) ⇒ Object

Similar to Rails’ built-in ‘content_for` except it defers any block execution and lets you pass arguments into it, like so:

 # Here we store a block with some eventual content…
 <% partial.content_for :title do |tag|
   <%= tag.h1 %>
 <% end %>

# …which is then invoked with some predefined options later.
<%= partial.content_for :title, tag.with_options(class: "text-bold") %>

def content_for(name, content = nil, *arguments, &block)
  @contents[name].content_for(content, *arguments, &block)
end

#content_for?(name) ⇒ Boolean

Returns:

  • (Boolean)
