更新:我找到解决方案,查看此页面的底部...
我有一个Node.js ,Express,MongoDB,Mongoose项目写在CoffeScript和我可以创建和读取数据,但我不能更新。
这是我的代码看起来像; p>
app.js
#update app.put /admin/:id.:format?,(req,res) - > Content.findById req.body.content.id,(err,c) - > c.title = req.body.content.title c.body = req.body.content.body c.save(err) - > 切换req.params.format 当json res.send c .__ doc else res.redirect/ adminedit.jade
h2编辑内容 form(method ='post',action ='/ admin /'+ c.id) input(name ='content [id]',value = c.id,type = 'hidden') input(name ='_ method',value ='PUT',type ='hidden') div 标签: input [title]',value = c.title ||'') div 标签Body: textarea(name ='content [body]')= c.body || '' div input(type ='submit',value ='Save')$ b b
这是我的控制台说

无法POST / admin / 4e96ec17fd7da7cb18000001
解决方案
我在 http:// expressjs上找到了解决方案 / guide.html :
当使用PUT等表单的方法时,我们可以使用一个名为_method的隐藏输入,为了这样做,我们首先需要methodOverride中间件,它应该放在bodyParser 下面,以便它可以利用它的req.body包含表单值。
app.use express.bodyParser() app.use express.methodOverride()
Update: I found the solution, look in the bottom of this page...
I've got a Node.js, Express, MongoDB, Mongoose project written in CoffeScript and I can create and read data, but I can't update.
This is what my code looks like;
app.js
# update app.put "/admin/:id.:format?", (req, res) -> Content.findById req.body.content.id, (err, c) -> c.title = req.body.content.title c.body = req.body.content.body c.save (err) -> switch req.params.format when "json" res.send c.__doc else res.redirect "/admin"edit.jade
h2 Edit Content form(method='post', action='/admin/' + c.id) input(name='content[id]', value=c.id, type='hidden') input(name='_method', value='PUT', type='hidden') div label Title: input(name='content[title]', value=c.title || '') div label Body: textarea(name='content[body]')=c.body || '' div input(type='submit', value='Save')And this is what my console says
127.0.0.1 - - [Thu, 13 Oct 2011 21:39:55 GMT] "POST /admin/4e96ec17fd7da7cb18000001 HTTP/1.1" 404 - "localhost:1234/admin/4e96ec17fd7da7cb18000001/edit" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_1) AppleWebKit/535.2 (KHTML, like Gecko) Chrome/15.0.874.83 Safari/535.2"And this is what my browser tells me
Cannot POST /admin/4e96ec17fd7da7cb18000001解决方案
I found the solution on expressjs/guide.html:
"When using methods such as PUT with a form, we can utilize a hidden input named _method, which can be used to alter the HTTP method. To do so we first need the methodOverride middleware, which should be placed below bodyParser so that it can utilize it’s req.body containing the form values."
app.use express.bodyParser() app.use express.methodOverride()
