Rails與json的respond_to問題

我正在做一些HTML5上傳和遇到一個問題，我似乎無法弄清楚。拿這個功能代碼：Rails與json的respond_to問題

if @image.save 
    render :json => {:status => "Successfully uploaded image!"} 
else 
    render :json => {:status => "Something went wrong with your upload!"} 
end

這是行之有效的，它確實如其所料。然而，當我添加的respond_to趕上HTML請求，它徹底失敗（雖然HTML部分工作。）

respond_to do |format| 
    if @image.save 
     format.html {redirect_to(edit_product_path(@image.product), :notice => "Your image was added successfully.")} 
     format.json {render :status => "Successfully uploaded image!"} 
    else 
     format.html {redirect_to(edit_product_path(@image.product), :alert => "An error occurred while attempting to upload your image. Please try again.")} 
     format.json {render :status => "Something went wrong with your upload!"} 
    end 
end

任何想法可能是錯誤的？我覺得我正在俯視簡單的事情。謝謝。

編輯 - 已解決的問題

我想這是我一直俯瞰着愚蠢的事。原來請求是HTML，而不是JSON，這是因爲上傳需要內容類型爲multipart/form-data，respond_to觸發了HTML。

Firebug只顯示： JSON.parse：意外字符 return window.JSON.parse（data）; – Orlando 2012-07-12 04:14:29

你需要渲染響應爲JSON

# old 
format.json {render :status => "Successfully uploaded image!"} 

# new 
format.json { render(:json => { :status => "Successfully uploaded image!" }) }

渲染需要一個狀態代碼，所以下面將不工作

format.json {render :status => "Something went wrong with your upload!"}

你可以寫出來作爲

format.json {render :error => "Something went wrong with your upload!", :status => :bad_request }
