我正在尝试用Sequelize形成一个查询。我需要限制结果，而是我得到错误：“表'表演者'缺少FROM子句条目”。可以预料，因为限制是一个单独的请求。要使用“子查询：false ”是不可能的，因为限制无法正常工作。
查询代码：
// find the events for the given venues, performers, ParentEvent and date
return this._events.findAll({
where: {
$or: [
{ short_desc: { ilike: '%' + props.keyword + '%' } },
{ search_terms: { ilike: '%' + props.keyword + '%' } },
{ '$Performers.name$': { ilike: '%' + props.keyword + '%' } },
{ '$ParentEvent.name$': { ilike: '%' + props.keyword + '%' } },
{ '$ParentEvent.search_terms$': { ilike: '%' + props.keyword + '%' } },
{ '$Venue.name$': { ilike: '%' + props.keyword + '%' } },
{ '$Venue.previous_name$': { ilike: '%' + props.keyword + '%' } },
{ '$Venue.search_terms$': { ilike: '%' + props.keyword + '%' } }
],
date_start: { $gt: new Date() },
$and: [ { '$Venue.suburb$': props.suburb }, { '$Venue.postcode$': props.postcode } ]
},
include: [
{ model: SubCategory },
{ model: Venue },
{ model: Performer },
{ model: ParentEvent }
],
offset: page * limit,
limit: limit
});
})
.then( events => ( events ) )
表演者模特：
'use strict';
module.exports = function(sequelize, DataTypes) {
var Performer = sequelize.define('Performer', {
id: {
type: DataTypes.UUID,
defaultValue: DataTypes.UUIDV1,
primaryKey: true
},
name: DataTypes.STRING,
description: DataTypes.TEXT,
short_name: DataTypes.STRING,
search_terms: DataTypes.STRING
}, {
classMethods: {
associate: function(models) {
Performer.belongsToMany( models.Event, {
through: "PerformerEvents"
});
Performer.belongsTo( models.SubCategory );
}
}
});
return Performer;
};

Event.belongsTo( models.ParentEvent, {foreignKey: 'ParentEventId', onDelete: 'CASCADE', onUpdate: 'CASCADE' } );
}

return Event;

有关如何正确形成此查询的任何建议吗？
