我有這樣的形式創建主題(又名標籤):HTML是不被過濾
<%= simple_form_for @video, :url => {:action => "topic_update"}, :html => {:id => "topic_form"}, :remote => true do |f| %>
<div class="topic_field_input">
<%= f.input :topic_names, :class => "topic_field", :label => false, :placeholder => "Type a topic (enter to create new one)" %>
</div>
<% end %>
我創建它作爲一個虛擬屬性:
attr_accessor :topic_names
after_save :assign_topics
def assign_topics
self.topics << @topic_names.map do |name|
Topic.find_or_create_by_name(name.split(' ').map {|w| w.capitalize }.join(' '))
end
end
end
我認爲它不」 t過濾html,因爲我要傳遞給find_or_create_by_name
如何修改代碼以過濾html?
off topic,but'name.split('').map {| w | w.capitalize} .join('')'可以替換爲'name.titleize()' – 2011-06-03 21:27:54
