How To Translate Mysql Query To Sequelize Orm
I need to perform this multiple LEFT JOIN query with sequelize: SELECT movie, genre FROM `yt_movies` M LEFT JOIN `genres_link` GL ON M.id = GL.movie_id LEFT JOIN `genres` G ON GL.
Solution 1:
To join A->B->C, you should nest the include for C inside the include for B, e.g.
A.findAll({
include: [
{
model: B,
include: [
{model: C}
]
}
]
})
But, if table genres_link has no attributes other than PKs of movie and genre, then use through.
YtMovies.belongsToMany(Genres, {through:GenresLink, foreignKey:'movie_id' });Genres.belongsToMany(YtMovies,{through:GenresLink,foreignKey:'genre_id '});YtMovies.findAll({include: [
{
model:Genres,
required :true,
through:GenresLink
}
]
});
The manual has some helpful info on this topic...
