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 generated by the SailsJS framework.
Is there a way to assign the value of the property generated by the SailsJS framework to an attribute that I have defined? For example:
attributes: {
...
creationDate:{
columnName:'cre_dt',
type:'datetime',
defaultsTo: this.createdAt
}
...
}
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.
You could remap the following way:
attributes: {
createdAt: {
type: 'datetime',
columnName: 'cre_dt'
},
updatedAt: {
type: 'datetime',
columnName: 'upd_dt'
},
// your other columns
}
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.
