目前,我有我要崩潰了爲三種方式:如何動態更改path_to()?
def send_email(contact,email)
end
def make_call(contact, call)
return link_to "Call", new_contact_call_path(:contact => contact, :call => call, :status => 'called')
end
def make_letter(contact, letter)
return link_to "Letter", new_contact_letter_path(:contact => contact, :letter => letter, :status => 'mailed')
end
我想這三個摺疊成一個,這樣我就可以通過模型的參數之一,它仍然可以正確地創建了path_to。我想通過以下要做到這一點,但堅持:
def do_event(contact, call_or_email_or_letter)
model_name = call_or_email_or_letter.class.name.tableize.singularize
link_to "#{model_name.camelize}", new_contact_#{model_name}_path(contact, call_or_email_or_letter)"
end
感謝的答案在這裏,我曾嘗試以下,這讓我更接近:
link_to("#{model_name.camelize}", send("new_contact_#{model_name}_path",
:contact => contact,
:status => "done",
:model_name => model_name))
但我似乎無法弄清楚如何在#{model_name}爲「:」屬性時將它過去,然後將model_name的值發送,而不是字符串,而是引用該對象。
我得到這個工作: - 給點Kadada,因爲他在正確的方向:)
def do_event(contact, call_or_email_or_letter)
model_name = call_or_email_or_letter.class.name.tableize.singularize
link_to("#{model_name.camelize}", send("new_contact_#{model_name}_path",
:contact => contact,
:status => 'done',
:"#{model_name}" => call_or_email_or_letter))
end
您好,感謝 - 我得到一個「有鑰匙?」錯誤? – Angela 2010-05-08 16:08:18
我創建新路徑的「手動編碼的方式」是這樣的:new_contact_letter_path(:contact => contact,:letter => letter,:status =>'郵寄')我擡頭看「send」以瞭解它是如何工作的。 。你能幫我嗎? – Angela 2010-05-08 16:10:34
我更新了我的問題,包括我根據您的建議嘗試了...除了model_name之外的關閉....謝謝!您一直很有幫助,很棒 – Angela 2010-05-08 16:26:55
