我正在使用jQuery file Upload,与承运人wave一道进行上载图像。
我设法通过下列网站开展工作:,手册,它完全有助于上载单一图像,但一旦我添加了超文本5多个属性,以便一劳永逸地上载多图像并选择多图像,我就在每项请求中发现错误。
NoMethodError in Advertiser::MediaController#create
undefined method `[] for nil:NilClass
对我来说,每一项请求似乎都完全相同,我似乎无法说明为什么它能够载上多种图像,但能够上载单一图像,如果我有多个属性,我甚至可以把单一图像上载,但一旦我拿走,再把工作上载到>。 j Query file Upload完全能够上载多种图像,而且你可以在其清点中加以核对。
令人非常赞赏的是,在什么地方要挖掘。
事先感谢你。
