I have issues, when running: sequelize db:migrate under MS SQL. I have a contact model that belongsTo 2 other models. So I added this to the contact.associate = function(models) function:

contact.belongsTo(models.job)
contact.belongsTo(models.customer)

The migration for the contact model looks like this:

 id: {
    allowNull: false,
    autoIncrement: true,
    primaryKey: true,
    type: Sequelize.INTEGER
  },
...
jobId: {
    type: Sequelize.INTEGER,
    references: {
      model: "jobs",
      key: "id"
    }
  },
customerId: {
    type: Sequelize.INTEGER,
    references: {
      model: "customers",
      key: "id"
    }
  },

The models, that I am trying to associate to the contact model are named: job and customer, their tables: jobs and customers

The error I got when running with the --debug Flag:

== 20181201143147-create-productionstep: migrating =======
ERROR: SequelizeDatabaseError: Could not create constraint or index. See         
previous errors.

Without the flag: 

ERROR: Could not create constraint or index. See previous errors.

There are no previous errors logged.

I have checked, that the PrimaryKey of the customers and jobs tables are named id and that the tables are created in the database
Sincerly, Jan

Edit: I have commented out both of the jobId and customerId objects and it migrates then, once undone, I have tried adding only one, but it fails with the same error again

Okay, I have managed to resolve the Issue, by creating a seperate migration for the foreign keys:

  up: (queryInterface, Sequelize) => {
return queryInterface.addColumn(
  'contacts',
  'jobId',
  {
    type: Sequelize.INTEGER,
    references: {
      model: "jobs",
      key: "id"
    },
    onDelete: 'SET NULL'
  },
)
  .then(() => {
    return queryInterface.addColumn(
      'contacts',
      'customerId',
      {
        type: Sequelize.INTEGER,
        references: {
          model: "customers",
          key: "id"
        },
        onDelete: 'SET NULL'
      }
    )
  })
},

down: (queryInterface, Sequelize) => {
return queryInterface.removeColumn(
  'contacts',
  'jobId',
)
  .then(() => {
    return queryInterface.removeColumn(
      'contacts',
      'customerId',
    )
  })
}

delete the sequelize meta file inside ms-sql and re run migration.

I had a similar error, so I tried to ran the sql statement on MSSQL and manage to get the previous error:

Introducing FOREIGN KEY constraint 'FK__tbQuestio__userU__232A17DA' on table 'tbQuestions' may cause cycles or multiple cascade paths

I had two tables connected to another one, so I had to add onDelete: "NO ACTION" to prevent the error and worked. I don't know if is worth mention it, but some one could give it a try.
