我想弄清楚如何将 bulkCreate 方法与我的 jQuery 字段值一起使用。目前，我正在尝试传递数组中字段的值，并希望将每个值解析为一个新记录，但它看起来不像这种方法那样工作，因此我收到一个错误:
Error during Post: SequelizeDatabaseError: ER_PARSE_ERROR: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '['Test 1','Test 2','Test 3'],'6','2016-02-01 03:26:59','2016-02-01 03:26:59')' at line 1
这是因为我实际上应该在路由中应用循环逻辑来处理不同的值吗？我应该改变 jQuery 吗？
查看文件(discoveryName 是bulkCreate 的字段):
<!DOCTYPE html>

<input type="text" class="form-control" id="sign-up-organization" name="organizationName" value="" placeholder="Company/Organization">

</form>

<script type="text/javascript">
$(function() {
var dataSourceField = $('#sign-up-organization-discovery-source');
var i = $('#sign-up-organization-discovery-source p').size();
var sourceCounter = 1;
$('#sign-up-add-discovery-source').on('click', function() {
$('<p><label for="discovery-source-field"><input type="text" id="discovery-source-field" size="20" name="discoverySource[{'+ sourceCounter++ +'}]" value="" placeholder="Discovery Source" /></label> <a href="#" class="remove">Remove</a></p>').appendTo(dataSourceField);
i++;
return false;
});
$('#sign-up-organization-discovery-source').on('click', '.remove', function() {
if (i > 1) {
$(this).parent('p').remove();
i--;
}
return false;
});
});
</script>
</body>
路线:
var express = require('express');
var appRoutes = express.Router();
var passport = require('passport');
var localStrategy = require('passport-local').Strategy;
var models = require('../models/db-index');
appRoutes.route('/sign-up/organization/discovery-source')
.get(function(req, res){
models.Organization.find({
where: {
organizationId: req.user.organizationId
}, attributes: ['organizationId']
}).then(function(organization){
res.render('pages/app/sign-up-discovery-source.hbs',{
organization: organization
});
});
})
.post(function(req, res){
models.DiscoverySource.bulkCreate([
{
discoverySource: req.body.discoverySource,
organizationId: req.body.organizationId
}
]).then(function(){
return models.DiscoverySource.findAll();
}).then(function(discoverySource){
console.log(discoverySource);
res.redirect('/app');
}).catch(function(error){
res.send(error);
console.log('Error during Post: ' + error);
});
});
DiscoverySource 模型字段:
discoverySourceId: {
type: DataTypes.INTEGER,
field: 'discovery_source_id',
autoIncrement: true,
primaryKey: true
},
discoverySource: {
type: DataTypes.STRING,
field: 'discovery_source'
},
organizationId: {
type: DataTypes.TEXT,
field: 'organization_id'
},
最佳答案
使用 .bulkCreate 您需要传递一个将被转换为行的对象数组。
.post(function(req, res){
var sources = _.map(req.body.discoverySource, function (source) {
return {
discoverySource: source,
organizationId: req.body.organizationId
};
});
models.DiscoverySource.bulkCreate(sources)
.then(function(){
return models.DiscoverySource.findAll();
}).then(function(discoverySource){
console.log(discoverySource);
res.redirect('/app');
}).catch(function(error){
res.send(error);
console.log('Error during Post: ' + error);
});
});
