如何在rails 4中使用carrierwave和嵌套窗體上載文件？

嘿，我有一個上傳文件的問題。我正在使用carrierwave上傳文件和嵌套表單以捕獲用戶的文件。當我提交頁面時，所有內容都可以正常工作，但不會上傳文件，也不會保存在數據庫中。 https://gist.github.com/jpstokes/10276415 如何在rails 4中使用carrierwave和嵌套窗體上載文件？

你能分享，當你提交與上傳文件嵌套形式生成的服務器日誌？ –

請分享'ApplicantsController'中的'permit'相關代碼，以便我可以相應地起草我的答案。 –

按照服務器日誌，有一個警告Unpermitted parameters: resumes_attributes, job_id。

您需要在此處執行的操作是在ApplicantsController中允許resumes_attributes和job_id。

例如：

def applicant_params 
    params.require(:applicant).permit(:fname, :lname, :phone,..., resumes_attributes: [:name, :attachment,...]) 
    end
