Instance Method Details

#partial(partial_name, local_variables = {}) ⇒ Object

Renders a partial specified by partial_name minus the extension. You can optionally specify a hash of local_variables which will be available while rendering the partial.

Consider a partial named foo.html.erb, in the same directory as the template, containing the following:

Text: <%= text %>

This partial can now be rendered like this:

partial('foo', :text => 'bar') # => "Text: bar"

  erb html_template_file(partial_name), binding
