在Rails上使用ambethia的reCAPTCHA插件3.覆盖flash消息div默认值？

Question

我在Rails 3上运行了ambethia的reCAPTCHA插件.有谁知道如何覆盖它的flash消息标记？我想重用我自己的flash_errordiv id而不是使用插件的flash_recaptcha_errordiv id:

<div id="flash_recaptcha_error">incorrect-captcha-sol</div>

另外,你如何清理这个控制器#create？

def create
  @post = Post.new(params[:post])
  respond_to do |format|
    if verify_recaptcha(:model => @post, :error => "reCAPTCHA incorrect. Try again.") && @post.save
      flash.now[:notice] = "Created \"#{@post.title}\""
      format.html { redirect_to(@post, :notice => 'Post was successfully created.') }
    else
      flash.now[:error] = "Incorrect word verification. Are you sure you\'re human?"
      format.html { redirect_to(:back, :error => 'reCAPTCHA incorrect. Try again.') }
    end
  end
end

感谢您阅读我的问题.

因为flash []是一个数组,你可以删除它里面的元素.当我们使用recaptcha gem时,flash数组包含recaptcha_error元素,所以你只需要在控制器中删除这个元素: flash.delete(:recaptcha_error).

例如 :

if  verify_recaptcha(:model=>@object,:message=>"Verification code is wrong", :attribute=>"verification code") && @object.save
  #your code if succes
else
  flash.delete(:recaptcha_error)
  #your code if its fail
end

也许它可以帮助你.谢谢
