我一直在努力让Omniauth与多个提供商工作了几天。我终于拥有它（主要是）工作 - Facebook和Twitter按预期工作同步，但是我遇到了Steam的问题。Rails控制器返回undefined方法'保存'，但无论如何保存
class AuthenticationsController < ApplicationController
skip_before_action :verify_authenticity_token, :only => :steam
def index
@authentications = current_user.authentications.all
end
# <%= link_to 'Authentications', authentications_path %>
def home
end
def twitter
omni = request.env["omniauth.auth"]
authentication = Authentication.find_by_provider_and_uid(omni['provider'], omni['uid'])
if authentication
flash[:notice] = "Logged in Successfully"
sign_in_and_redirect User.find(authentication.user_id)
elsif current_user
token = omni['credentials'].token
token_secret = omni['credentials'].secret
current_user.authentications.create!(:provider => omni['provider'],
:uid => omni['uid'],
:token => token,
:token_secret => token_secret)
flash[:notice] = "Authentication successful."
sign_in_and_redirect current_user
else
user = User.new
user.apply_omniauth(omni)
raise user.inspect
if user.save
flash[:notice] = "Logged in."
sign_in_and_redirect User.find(user.id)
else
session[:omniauth] = omni.except('extra')
redirect_to new_user_registration_path
end
end
end
def destroy
@authentication = Authentication.find(params[:id])
@authentication.destroy
redirect_to authentications_url, :notice => "Successfully destroyed authentication."
end
def facebook
omni = request.env["omniauth.auth"]
authentication = Authentication.find_by_provider_and_uid(omni['provider'], omni['uid'])
if authentication
flash[:notice] = "Logged in Successfully"
sign_in_and_redirect User.find(authentication.user_id)
elsif current_user
token = omni['credentials'].token
token_secret = ""
current_user.authentications.create!(:provider => omni['provider'],
:uid => omni['uid'],
:token => token,
:token_secret => token_secret)
flash[:notice] = "Authentication successful."
sign_in_and_redirect current_user
else
user = User.new
user.email = omni['extra']['raw_info'].email
user.apply_omniauth(omni)
if user.save
flash[:notice] = "Logged in."
sign_in_and_redirect User.find(user.id)
else
session[:omniauth] = omni.except('extra')
redirect_to new_user_registration_path
end
end
end
def steam
omni = request.env["omniauth.auth"]
authentication = Authentication.find_by_provider_and_uid(omni['provider'], omni['uid'])
if authentication
flash[:notice] = "Logged in Successfully"
sign_in_and_redirect User.find(authentication.user_id)
elsif current_user
token = omni['extra']['raw_info'].steamid
# render :text => request.env["omniauth.auth"].info.to_hash.inspect
puts token
token_secret = ""
current_user.authentications.create!(:provider => omni['provider'],
:uid => omni['uid'],
:token => token,
:token_secret => token_secret)
flash[:notice] = "Authentication successful."
sign_in_and_redirect current_user
else
user = User.new
user.apply_omniauth(omni)
end
if user.save
flash[:notice] = "Logged in."
sign_in_and_redirect User.find(user.id)
else
session[:omniauth] = omni.except('extra')
redirect_to new_user_registration_path
end
end
end
正如你可以看到twitter功能和steam几乎是重复的 - 他们引用User model这是内部的功能
def apply_omniauth(omni)
authentications.build(:provider => omni['provider'],
:uid => omni['uid'],
:token => omni['credentials'].token,
:token_secret => omni['credentials'].secret)
end
目前汽将与undefined method 'save' for nil 上回应
if user.save
flash[:notice] = "Logged in."
sign_in_and_redirect User.find(user.id)
else
让我感到困惑的是它实际上是储蓄。

我删除记录 - 然后去重新授权，并获得相同的错误，但关系确实存在。
我不确定如何打印出user以查看它发生了什么，或者如何在此内部进行错误测试。
欢迎任何反馈，对于这个宝石已经很长时间了。
我没有想到会这样，但我得到它。我所苦苦挣扎的，从技术上讲不应该击中那个'别的'。当它同步我时，它会触及'elsif current_user'，然后继续下去。我对轨道是新的，但我不明白为什么它在做elsif，然后也在做别的。 – DNorthrup
你没有做'else' :)你正在做下一个'if'，因为'sign_in_and_redirect'不会停止执行代码的其余部分。如果在下一个方法之后添加'return'，如果不执行。 – Ptr
感谢您的详细信息。我有种，但不完全。我尝试了'else'之上的返回，如果user.save在上面，我仍然在user.save上发生错误 - 你能告诉我一个你想要的例子吗？ – DNorthrup
