我对猫鼬/快车相当陌生。我正在努力尝试更新来自HTML表单的新数据并将其保存到具有引用的数据库。我有一个带位置模型位置参考的商业模型。这是代码。更新带有多个参考数据库问题的数据库
edit.ejs
<div class="container">
<div class="form-container">
<form action="/<%= bus._id %>?_method=PUT" method="POST">
<!-- business info -->
<h3>Business Information</h3>
<input class="form-input" type="input" name="bus[logo]" value="<%= bus.logo %>">
<input class="form-input" type="input" name="bus[name]" value="<%= bus.name %>">
<% bus.location.forEach(function(location) { %>
<input class="form-input" type="input" name="bus.location[street]" value="<%= location.street %>">
<input class="form-input" type="input" name="bus.location[city]" value="<%= location.city %>">
<div class="state-input">
<select class="form-inline" name="bus.location[state]">
<option value="" disabled selected><%= location.state %></option>
<option value="AL">Alabama</option>
...
<option value="WY">Wyoming</option>
</select>
</div><!--State-input -->
<input class="form-inline" type="input" name="bus.location[zipcode]" value="<%= location.zipcode %>">
<% }) %>
<!--Contact info-->
<h4>Contact Information</h4>
<% bus.contact.forEach(function(contact) { %>
<input class="form-input" type="url" name="bus[url]" value="<%= bus.url %>">
<input class="form-input" type="email" name="bus.contact[email]" value="<%= contact.email %>">
<input class="form-input" type="tel" name="bus.contact[phone]" value="<%= contact.phone %>">
<input class="form-input" type="input" name="bus.contact[twitter]" value= "<%= contact.twitter %>">
<input class="form-input" type="input" name="bus.contact[facebook]" value="<%= contact.facebook %>">
<input class="form-input" type="input" name="bus.contact[instagram]" value="<%= contact.instagram %>">
<% }) %>
index.js - 编辑路线
//(edit.ejs) Edit Route
app.get('/:id/edit', function(req, res) {
Business.findById(req.params.id)
.populate('location')
.populate('contact')
.populate('images')
.exec(function(err, bus) {
if(err) {
console.log(err);
} else {
res.render('edit', {bus:bus});
}
});
});
app.put('/:id', function(req, res) {
Business.findByIdAndUpdate(req.params.id, req.body.bus, function(err, bus) {
if(err) {
console.log(err);
res.redirect('/' + req.params.id + '/edit');
} else {
res.redirect('/' + req.params.id);
}
});
});
业务(公交车)更新很好,但bus.location不更新。 商业模式
