Use included Models in Where Statements with Sequelize - postgresql

Question

I am using Sequelize 4.38.0, with Postgres. I am trying to implement a search feature. But I am having trouble validating the query. I have to check if the query matches a city. It doesn't have to necessarily match.
I want to move the query to the City Model to the top level WHERE like described here: http://docs.sequelizejs.com/manual/tutorial/models-usage.html#top-level-where-with-eagerly-loaded-models But I get this error: Unhandled rejection SequelizeDatabaseError: missing an entry for the "City" table in the FROM clause
Model Definition
const Property = sequelize.define('property', {
id: {
type: type.STRING,
unique: true,
allowNull: false,
primaryKey: true
},
name: {
type: type.STRING,
allowNull: false
},
// ...
isVisible: {
type: type.BOOLEAN,
default: false
}
});
const City = sequelize.define('city', {
name: {
type: type.STRING
},
}, {
timestamps: false,
});
The Query
sequelize.sync().then(() => {
let query = 'new';
let whereStatement = {
$or: [{
name: {
$ilike: '%' + query + '%'
}
},
{
description: {
$ilike: '%' + query + '%'
}
},
// I get the Error if I uncomment this
// {
// '$City.name$': {
// $ilike: '%' + query + '%'
// }
// }
]
};
Property.findAndCountAll({
where: whereStatement,
include: [{
model: City,
where: {
name: {
$ilike: '%' + query + '%'
}
}
// I want to move this where to the upper level
// where inside the OR opertator
},
{
model: Photo
}
],
distinct: true,
order: [
['createdAt', 'DESC']
]
}).then(properties => {
console.log(properties.count)
});
});
The Actual Query has a bit more attributes. The resultant SQL is:
Executing (default): SELECT "property".*, "city"."id" AS "city.id", "city"."name" AS "city.name", "city"."provinceId" AS "city.provinceId", "photos"."id" AS "photos.id", "photos"."location" AS "photos.location", "photos"."slug" AS "photos.slug", "photos"."description" AS "photos.description", "photos"."isPrimary" AS "photos.isPrimary", "photos"."createdAt" AS "photos.createdAt", "photos"."updatedAt" AS "photos.updatedAt", "photos"."propertyId" AS "photos.propertyId" FROM (SELECT "property"."id", "property"."webSlug", "property"."name", "property"."description", "property"."direction", "property"."price", "property"."areaConstruction", "property"."areaLot", "property"."isVisible", "property"."isAvailable", "property"."isNegociable", "property"."isRural", "property"."latitude", "property"."longitude", "property"."map_radio", "property"."video_url", "property"."createdAt", "property"."updatedAt", "property"."cityId", "property"."propertyTypeId" FROM "properties" AS "property" WHERE ("property"."name" ILIKE '%My Query%' OR "property"."description" ILIKE '%My Query%' OR "property"."id" ILIKE '%My Query%' OR "properties_city"."name" ILIKE '%My Query%') AND "property"."isVisible" = true ORDER BY "property"."createdAt" DESC LIMIT 10 OFFSET 0) AS "property" LEFT OUTER JOIN "cities" AS "city" ON "property"."cityId" = "city"."id" LEFT OUTER JOIN "photos" AS "photos" ON "property"."id" = "photos"."propertyId" ORDER BY "property"."createdAt" DESC;
Update
If I use the same Models and same whereStatement but i change the findAndCountAll() function to a findAll() the search feature works propertly and I can add the '$city.name$': { $ilike: '%' + query + '%' } to the upper WHERE.
Property.findAll({
where: whereStatement,
include: [{model: City}, {model: Photo}],
distinct: true,
order: [['createdAt', 'DESC']],
}).then(properties => {
res.render('search', {
title: 'Buscar',
properties: properties,
query: query,
propertyTypeId: propertyTypeId,
propertyTypes: req.propertyTypes,
})
})
The SQL output:
Executing (default): SELECT "property"."id", "property"."webSlug", "property"."name", "property"."description", "property"."direction", "property"."price", "property"."areaConstruction", "property"."areaLot", "property"."isVisible", "property"."isAvailable", "property"."isNegociable", "property"."isRural", "property"."latitude", "property"."longitude", "property"."map_radio", "property"."video_url", "property"."createdAt", "property"."updatedAt", "property"."cityId", "property"."propertyTypeId", "city"."id" AS "city.id", "city"."name" AS "city.name", "city"."provinceId" AS "city.provinceId", "photos"."id" AS "photos.id", "photos"."location" AS "photos.location", "photos"."slug" AS "photos.slug", "photos"."description" AS "photos.description", "photos"."isPrimary" AS "photos.isPrimary", "photos"."createdAt" AS "photos.createdAt", "photos"."updatedAt" AS "photos.updatedAt", "photos"."propertyId" AS "photos.propertyId" FROM "properties" AS "property" LEFT OUTER JOIN "cities" AS "city" ON "property"."cityId" = "city"."id" LEFT OUTER JOIN "photos" AS "photos" ON "property"."id" = "photos"."propertyId" WHERE ("property"."name" ILIKE '%City_Query%' OR "property"."description" ILIKE '%City_Query%' OR "property"."id" ILIKE '%City_Query%' OR "city"."name" ILIKE '%City_Query%') AND "property"."isVisible" = true ORDER BY "property"."createdAt" DESC;

Try this it should work. include
"duplicating":false
in this
sequelize.sync().then(() => {
let query = 'new';
let whereStatement = {
$or: [{
name: {
$ilike: '%' + query + '%'
}
},
{
description: {
$ilike: '%' + query + '%'
}
},
{
'$City.name$': {
$ilike: '%' + query + '%'
}
}
]
};
Property.findAndCountAll({
where: whereStatement,
include: [{
model: City,
attributes: [],
duplicating:false
},
{
model: Photo
}
],
distinct: true,
order: [
['createdAt', 'DESC']
]
}).then(properties => {
console.log(properties.count)
});
});
