我在 Railscast espisode #197 中使用了有关如何添加动态输入字段的方法细节,但我不确定如何为其编写 RSpec 测试。建议?
def link_to_add_fields(name, f, association, path, *args)
new_object = f.object.class.reflect_on_association(association).klass.new
fields = f.semantic_fields_for(association, new_object, :child_index => "new_#{association}") do |builder|
render(path + association.to_s.singularize + "_fields", :builder => builder)
end
link_to_function(name, "add_fields(this, \"#{association}\", \"#{escape_javascript(fields.html_safe)}\")", *args)
end
