此功能在application_help.rb定義:Rails的url_for的Gravatar路由錯誤
def gravatar_url_for(email, options = {})
url_for(
{
:protocol => 'http://',
:host => 'www.gravatar.com',
:controller => 'avatar',
# :controller => 'avatar.php',
:gravatar_id => Digest::MD5.hexdigest(email),
:only_path => false
}.merge(options)
)
end
它在視圖中使用:
<%= image_tag(gravatar_url_for user.email, {:d => 'identicon', :s => 32, :r => 'g'}) %>
偶爾,它的使用將導致路由錯誤:
No route matches {:controller=>"avatar", :d=>"identicon", :r=>"g", :gravatar_id=>"486575e581db04b7c8ca218af8488657", :s=>32}
發生錯誤時正在提供有效的電子郵件。
如果我用這種邏輯取代url_for(),它按預期工作:
url_for("http://www.gravatar.com/avatar/" + Digest::MD5.hexdigest(email) + "?d=identicon&s=40&r=g")
**編輯** 我已經刪除從routes.rb中文件中的以下行:
# This is a legacy wild controller route that's not recommended for RESTful applications.
# Note: This route will make all actions in every controller accessible via GET requests.
match ':controller(/:action(/:id(.:format)))'
有沒有辦法讓url_for在沒有'傳統野外控制器路線'的情況下工作?
