我正在使用Node.js,Express和MethodOverride尝试让表单更新模型的一部分(我的用户模型)。
用户模型:
var userSchema = new mongoose.Schema({
email: { type: String, unique: true, lowercase: true },
password: String,
profile: {
name: { type: String, default: 'Company Name' },
location: { type: String, default: 'Location' },
website: { type: String, default: 'Your Website' },
picture: { type: String, default: '' }
},
assetNumPre: { type: String, default: 'test' }, // this is the one I want to change
});
module.exports = mongoose.model('User', userSchema);
HTML表单:
<form role="form-inline"action="/dashboard/settings/assetNumber?_method=PUT" method="POST">
<div class="col-md-3">
<div class="form-group">
<label for="prefix" class="control-label">Prefix for Asset Number</label>
<br>
<small>Any alphanumeric characters to a limit of 6</small>
<input type="text" class="form-control" id="prefix" name="prefix" placeholder="Prefix max 6 characters" maxlength="6" value="{{ prefix }}">
</div><!-- Prefix for Asset Number-->
<br>
<div class="box-footer">
<button type="submit" class="btn btn-primary">Submit</button>
</div>
</div>
</form>
然后路线:
app.put('/dashboard/settings/assetNumber',
setRender('dashboard/settings/assetNumbers'),
setRedirect({auth: '/login'}),
isAuthenticated,
dashboard.getDefault,
(req, res) => {
var prefix = req.body.prefix;
console.log(req.params);
User.findByIdAndUpdate({_id: req.params.user_id}, prefix, function(err, UpdatedUser) {
if (err) {
res.send(err);
}
console.log(UpdatedUser);
});
res.locals.prefix = req.user.assetNumPre;
});
我的路线遗失的一件事是req.user.assetNumPre
,我需要保存它,但我不知道如何执行此PUT
请求。文档也没有多大帮助。
我几天前从Stack Overflow示例中获取了该路由,但找不到它的链接。我的app.js方法覆盖工作,因为我已经完成了DELETE
个请求。该模型具有正确的字段,并具有显示在我的显示页面中的默认测试值。
答案 0 :(得分:1)
你在说这个:
User.findByIdAndUpdate({_id: req.params.user_id}, prefix...
但前缀只是值:
var prefix = req.body.prefix;
findByIdAndUpdate
takes an Object,而非值,用于更新特定字段。
所以试试:
User.findByIdAndUpdate({_id: req.params.user_id}, { assetNumPre: prefix }...

这是固定路线:
app.put('/dashboard/settings/assetNumber',
setRedirect({auth: '/login', success: '/dashboard/settings/assetNumber', failure: '/dashboard/settings/assetNumber'}),
isAuthenticated,
(req, res) => {
User.findById(req.user.id, function(err, user) {
if (err) return (err);
user.assetNumPre = req.body.prefix || 'pre';
user.save(function(err) {
if (err) return (err);
req.flash('success', { msg: 'Asset Number Prefix updated.' });
res.redirect(req.redirect.success);
});
});
res.locals.prefix = req.user.assetNumPre;
});
所以改变了一些不属于问题的事情。我想我需要在回调函数中设置数据。然后做一个user.save
。
