部分解决


在create.jade模板中的
enctype=“multipart/form data”
的表单中使用有问题，如果没有这个，我可以将字段信息添加到
req.body
属性中，如req.body.projectName、
req.body.plane、
req.body.details
。。。我需要解决enctype出现的问题，并将文件保存在一个文件夹中，路径保存在数据库中。

嗨，挑剔的人，你好吗？代替这些路由：
router.get（'/create'，controller.create）
和
router.post（'/create'，projectController.saveProject），更加restful，避免使用动词。您正在阅读和创建项目，因此选择
router.get（'/project/:id'，projectController.read）
和
router.post（'/project'，projectController.create）。从长远来看，这会让你的生活更轻松。谢谢你，诺德曼，但这不是问题所在。在
saveProject
上，在
ImageSavePath.array（req.body.image[5]）之后，如果执行console.log（ImageSavePath），您会看到什么。它是一个包含路径的字符串元素的数组吗？此行不起作用。错误是什么？或者没有错误，只是空字符串？其他一切都正常吗？Multer正在正确处理文件，您就是无法获取文件名？我正在检查multer页面，没有看到“重命名”选项
ImageSavePath
是一个multer对象，而
.array
只是将数据传递给它，对吗？您正在尝试将multer对象保存为模型上的字符串。您是否检查过是否有类似于
ImageSavePath.filename
的内容可以传递给您的模型？嗨，这里的挑剔者，你好吗？代替这些路由：
