我一直在捣乱我的大脑数小时倾注文件，我不能为我的生活弄清楚什么是错的。表单接受图像，但不会触发直接上传。我的文件如下。

*请注意上面的CLOUD_NAME，API_KEY，SIGNATURE，AUTHENTICITY_TOKEN和SECRET_KEY都填写了正确的信息，但已被删除帖子。此外，cloudinary_cores.html文件位于我的public目录中。
我已尝试按照Cloudinary Gems repo and on their help docs上的说明操作，但无法弄清问题是什么。
如果还有其他任何人需要，请告诉我。

因此，事实证明turbolinks宝石是罪魁祸首。通过将scripts.js更改为以下内容，我现在正确上传。
注意：这是Turbolinks 5 的用法 - 以前的版本需要略有不同的设置。
<强> scripts.js中
// jQuery "$(document).ready()" equivalent for Trubolinks 5 usage
$(document).on('turbolinks:load', function() {
console.log("trubolinks:load - jQuery Ready!");
$(function() {
cloudinaryUploaderInit();
});
});
var cloudinaryUploaderInit = function() {
// console.log("cloudinaryUploaderInit");
if ($.fn.cloudinary_fileupload !== undefined) {
$("input.cloudinary-fileupload[type=file]").each(function() {
$(this).cloudinary_fileupload();
});
} else {
// console.log("`cloudinary_fileupload` is undefined");
}
}
编辑：或者（并且可能更适合），您可以使用此处概述的jquery-turbolinks gem：https://github.com/cloudinary/cloudinary_gem/issues/126
