Rails 3/Recaptcha安装 - 未定义的本地变量或方法`recaptcha_tags'

Question

当我尝试在Rails 3应用程序上安装Recaptcha时出现以下错误。我已将recaptcha标签放入我的_form文件中（请参阅下面的附件）。

Showing /Users/fkhalid2008/loand/app/views/posts/_form.html.erb where line #20 raised: 

undefined local variable or method `recaptcha_tags' for #<# <Class:0x12d4e1870>:0x12d4dac78> 
Extracted source (around line #20): 

17: <div class="actions"> 
18:  <%= f.submit %> 
19: </div> 
20: <%= recaptcha_tags %> 
21: <% end %> 

能否请您指教？

Posts控制器

def create 
@post = Post.new(params[:post]) 

respond_to do |format| 
if verify_recaptcha && @post.save 
format.html { redirect_to :action=> "index"} 
format.json { render :json => @post, :status => :created, :location => @post } 
else 
format.html { render :action => "new" } 
format.json { render :json => @post.errors, :status => :unprocessable_entity } 
end 
end 
end

我试图重现你的错误，而是通过Readme一切行走后运行良好。

您是否重新启动服务器？

的步骤i制备：

1. 生成API密钥
2. 创建的配置/初始化/ recaptcha.rb与您的代码和我的钥匙
3. 改变了我的形式与<％= recaptcha_tags％>
4. 重新启动服务器，初始化程序正在加载

就是这样......也许只是试一试吧时间。
