sequelize through table this is how a query on a column of a through table works. can't query directly on the through table.

sequelize.js

        this.models.myItem.findAll({
          where: { projectId: 1 },
          include: [
            {
              model: this.models.myItemThing,
              // Sequelize term indicates "use the through table where `type===foo`"
              through: {
                where: { type: "foo" },
              },
            },
          ],
        })
