What are you doing?

I have a model which is defined like

sequelize.define(‘Test’, {
      test_key: {
          field: ‘testKey’,
          type: DataTypes.BIGINT,
          allowNull: false
      },
})

Then I tried to generate the schema by calling

sequelize.sync({ alter: true, force: true })

I was expecting the column name to be created as "test_key", but it turns out to be "testKey"

And when I tried to call sync() without "alter:true" like

sequelize.sync({ force: true })

Everything works fine.
So there might be a issue for the alter functionality, please help to look into this.

What do you expect to happen?

I expected sync() with "alter:true" use the "field" option to create the column name.

What is actually happening?

But sync() with "alter:true" ignores the "field" option
