How to join to table with Sequelize without relations - sql

Question

I made an SQL command line to select what the data I want but I can't find a way to do it with Sequelize.
I have two tables. One with some id linked to names and the other one with long texts.
I want to select all the text containing names from the id of the name.
This SQL command is working :
SELECT
texts.id,
texts.content
FROM
text
INNER JOIN users AS u ON u.id=38
WHERE
LOWER(texts.content) like concat('%',u.name,'%')
When I try to do it with Sequelize, I have something like this :
this.modelTexts.findAll({
include: [
{
model: this.modelUsers,
where: { id: 38 },
}
],
where: ...
})
When I try this, I have this error message :
SequelizeEagerLoadingError: users is not associated to texts!
I know I have to make something like :
Users.hasMany(Texts)
But I can't find a way to make it.
Thanks for taking a bit of your time for this request !

Answer 1

You can use Sequelize Raw for this, so your query can be something like this
sequelize.query(`
SELECT
texts.id,
texts.content
FROM
text
INNER JOIN users AS u ON u.id=38
WHERE
LOWER(texts.content) like concat('%',u.name,'%')`
{ type: sequelize.QueryTypes.SELECT});
Or you can add associations. So wherever in your code you have define models, add the following code
User.hasMany('Text', {foreignKey: 'user_id'});

NB: this solution was associated but if what you mean is no foreign keys on both tables
To solve this, here is what i would do
I Added this to my association first
models.User.hasMany(models.Text)
then also added this in my find query
Text.findAll({
attributes: ['id', 'content'],
include: [
{
model: users,
on: Sequelize.literal('users.id = 13')
},
],
});

Answer 3

While the above answer is great, I think it may defeat the whole purpose of using sequelize. Have you tried the following:
In your Text model definition:
Text.associate = models => {
Text.belongsTo(models.User)
}
In your User model definition:
User.associate = models => {
User.hasMany(models.Text)
}
Let me know if you're still having trouble! Understanding how sequelize works will save you many many hours in the long run! :)
