sequelize: Not include model if where conditon of included model matches - node.js

Question

I want to get all RecurringEvents that have no excludeDates for today.
I have following models:
Recurring events
const RecurringEvent = sequelize.definge('recurringEvent,{
id: {type: Sequelize.INTEGER, primaryKey:true},
title: Sequelize.STRING
});
And ExcludeDates with a foreign key recurringEventId
const ExcludeDate = sequelize.define('exclude_date',{
id: {type: Sequelize.INTEGER, primaryKey:true},
recurringEventId: Sequelize.INTEGER,
date: Sequelize.DATE
});
As a relationship i defined
RecurringEvent.hasMany(ExcludeDate, {foreignKey: 'recurringEventId'});
I can get all my RecurringEvents including the the excludeDates with
RecurringEvent.findAll({include:[{model:ExcludeDate}]});
That will give me an output like:
[
{
"id": 1,
"title": "Event1",
"exclude_dates": [
{
"id": 1,
"date": "2019-02-13",
"recurringEventId": 1,
},
{
"id": 2,
"date": "2019-02-14",
"recurringEventId": 1,
}
]
Now i would like to get the Recurring events but only if there is no exclude date for today.
so far i have tried
RecurringEvent.findAll({
include: [{
model: ExcludeDate,
where: {
date: {
[Op.ne]: moment().format('YYYY-MM-DD')
}
}
}]
})
But that only leaves out the ExcludeDate entry with the current Date like that :
[
{
"id": 1,
"title": "Event1",
"exclude_dates": [
{
"id": 2,
"date": "2019-02-14",
"recurringEventId": 1,
}
]
How can i exclude the whole RecurringEvent if and ExcludeDate for it is set for today?
Edit:
I also read in the docs
To move the where conditions from an included model from the ON condition to the top level WHERE you can use the '$nested.column$'
So i have tried this:
RecurringEvent.findAll({where:{
'$exclude_dates.date$':{
[Op.ne]: moment().format('YYYY-MM-DD')
}
},
include: [{model: ExcludeDate}]
})
But without any luck, i'm still getting RecurringEvents just without the one exclude date in the exclude_dates property

Answer 1

Try to add required: true, to your include model to make inner join instead of left join. e.g.
RecurringEvent.findAll({
include: [{
model: ExcludeDate,
required: true,
where: {
date: {
[Op.ne]: moment().format('YYYY-MM-DD')
}
}
}]
})
