Sequelize Where On Many-to-many Join

I am hoping somebody can help me. I am using the Sequelize ORM for express.js and I have a working many-to-many relationship between 2 tables. For the sake of simplifying my query

Solution 1:

With Belongs-To-Many you can query based on through relation and select specific attributes. For example using findAll with through

User.findAll({
  include: [{
    model: Project,
      through: {
        attributes: ['createdAt', 'startedAt', 'finishedAt']
          where: {completed: true}
      }
   }] 
 });

Basically you can use through option and include the relationship that you linked. More can be found here
