Devise + OmniAuth for Facebook在遠程服務器上註冊

Question

我正在使用Devise + Omniauth在我的應用程序中啓用Facebook註冊。當我開發它時，我沒有遇到任何問題。將它部署到我的遠程服務器也一樣。問題是，其他人保持遇到了同樣的錯誤：

TypeError (no implicit conversion of Symbol into Integer): 
app/models/user.rb:67:in `find_for_facebook_oauth' 
app/controllers/users/omniauth_callbacks_controller.rb:4:in `facebook' 

我對用戶模型user.rb下面的代碼：

def self.find_for_facebook_oauth(data, signed_in_resource=nil) 
user = User.where(:email => data.info.email).first 
unless user 
    params = 
    { 
     :user => 
     { 
     :username => data.uid, 
     :email => data.info.email, 
     :password => Devise.friendly_token[0,20], 
     :user_profile_attributes => 
      { 
      :first_name => data.extra.raw_info.first_name, 
      :last_name => data.extra.raw_info.last_name, 
      :remote_image_url => data.extra.raw_info.image, 
      }, 
     :user_auths_attributes => 
     { 
      :uid => data.uid, 
      :provider => data.provider 
     } 
     } 
    } 
    user = User.create!(params[:user]) 
end 
return user 
end 

其中線67是user = User.create!(params[:user])

而且omniauth_callbacks_controller.rb：

def facebook 
# You need to implement the method below in your model (e.g. app/models/user.rb) 
@user = User.find_for_facebook_oauth(request.env["omniauth.auth"]) 

if @user.persisted? 
    sign_in_and_redirect @user, :event => :authentication #this will throw if @user is not activated 
    set_flash_message(:notice, :success, :kind => "Facebook") if is_navigational_format? 
else 
    session["devise.facebook_data"] = request.env["omniauth.auth"] 
    redirect_to new_user_registration_url 
end 
end 

第4行i小號@user = User.find_for_facebook_oauth(request.env["omniauth.auth"])

服務器日誌還示出了GET參數：

Parameters: {"code"=>"[some long string of number and letters]", "state"=>"[another string of numbers and letters]"} 

更新： 記錄器輸出下列爲request.env["omniauth.auth"]：

#<OmniAuth::AuthHash credentials=#<OmniAuth::AuthHash expires=true expires_at=1401992074 token="*"> extra=#<OmniAuth::AuthHash raw_info=#<OmniAuth::AuthHash email="*" first_name="*" gender="male" id="*" last_name="*" link="https://www.facebook.com/*" locale="en_US" name="*" timezone=8 updated_time="2014-04-05T09:29:22+0000" username="*" verified=true>> info=#<OmniAuth::AuthHash::InfoHash email="*" first_name="*" image="http://graph.facebook.com/*/picture?type=square" last_name="*" name="*" nickname="*" urls=#<OmniAuth::AuthHash Facebook="https://www.facebook.com/*"> verified=true> provider="facebook" uid="*"> 

更新2： 記錄的PARAMS [：用戶]提供以下值：

Params: {:username=>"*", :email=>"*", :password=>"iePVLt7XEWk4YwPjja6n", :user_profile_attributes=>{:first_name=>"*", :last_name=>"*", :remote_image_url=>"http://graph.facebook.com/*/picture?type=square"}, :user_auths_attributes=>{:uid=>"*", :provider=>"facebook"}} 

Answer 1

更新您的PARAMS哈希如下：

params = 
    { 
     :user => 
     { 
     :username => data.uid, 
     :email => data.info.email, 
     :password => Devise.friendly_token[0,20], 
     :user_profile_attributes => 
      { 
      :first_name => data.extra.raw_info.first_name, 
      :last_name => data.extra.raw_info.last_name, 
      :remote_image_url => data.info.image ## Removed comma and updated the method 
      }, 
     :user_auths_attributes => 
     [{ 
      :uid => data.uid, 
      :provider => data.provider 
     }] ## Enclosed within array [] brackets 
     } 
    } 

看着被你給params哈希表，我可以告訴大家，一個User和Profile有1-1 Relationship而User和Auths有1-M Relationship。在這種情況下，user_auths_attributes必須作爲Array傳遞。

TypeError (no implicit conversion of Symbol into Integer)

你都拿到上面的錯誤，因爲user_auths_attributes正在解釋爲一個數組，而不是一個哈希值。所以當Ruby看到params [：user] [：user_auths_attributes] [：uid]它試圖取最後一個鍵並將其變成params [：user] [：user_auths_attributes] [0]或至少找到一些整數值可以轉換爲索引數組。

Answer 2

我只發現了這個問題：

:remote_image_url => data.extra.raw_info.image # In data I see only data.info.image 

更換

:remote_image_url => data.info.image 

但它不是你的問題的解決方案。

嘗試從params[:user]調試數據。從異常看來，你使用一些散列屬性是整數。
