我在 Rails 中使用 authlogic-connect。我正在使用一个简单的 haml 模板,我不想在其中显示已添加的授权提供者。
%h2 My Account
%form.authentication_form{:action => connect_path, :method => :post}
%fieldset
%input{:type => :hidden, :name => :authentication_type, :value => :user}
%legend Add another Oauth or OpenID provider.
.oauth_providers
%ul
- %w(google facebook twitter yahoo).each do |name|
%li.oauth_provider
-unless "{user.authenticated_with}" =~ "{name}"
%img{:src => "/images/icons/#{name}.png"}
%input{:type => :radio, :id => "#{name}_oauth_provider", :name => :oauth_provider, :value => name}
.clearfix
%input.submit{:name => :submit, :type => :submit, :value => "Update"}/
我遇到错误类型不匹配:字符串。 user.authenticated with 返回一个字符串。
def authenticated_with
@authenticated_with ||= self.access_tokens.collect{|t| t.service_name.to_s}
end
可能的问题是什么?
堆栈跟踪:

提取的源代码(大约第 10 行): -- 在第 10 行显示错误
最佳答案
将正则表达式作为参数传递给 String#=~ :
>> string = "el"
>> "hello" =~ /#{string}/
=> 1
