Change field name for CreatedAt / UpdateAt Attributes

Question

I am attempting to model an existing MSSQL table in SailsJS. Unsurprisingly the tables in the existing database have a createdAt and updatedAt column similar to what is gene

Answer 1

No, but you can turn off the auto-generated property entirely and use your own:

autoCreatedAt: false,
autoUpdatedAt: false,
attributes: {
    creationDate: {
        columnName: 'cre_dt',
        type: 'datetime',
        defaultsTo: function() {return new Date();}
    },
    updateDate: {
        columnName: 'upd_dt',
        type: 'datetime',
        defaultsTo: function() {return new Date();}
    }
},
//Resonsible for actually updating the 'updateDate' property.
beforeValidate:function(values,next) {
    values.updateDate= new Date();
    next();
}

See the Waterline options doc.

Answer 2

Now it's possible to use the autoCreatedAt and autoUpdatedAt to set a custom name for these fields as described at http://sailsjs.com/documentation/concepts/models-and-orm/model-settings#?autocreatedat

If set to a string, that string will be used as the custom field/column name for the createdAt attribute.

Answer 3

You could remap the following way:

attributes: {
    createdAt: {
      type: 'datetime',
      columnName: 'cre_dt'
    },
    updatedAt: {
      type: 'datetime',
      columnName: 'upd_dt'
    },
    // your other columns
  }
