|
|
*
|
|
* The table columns are defined by the hash that is given as the second argument. Each attribute of the
|
|
* hash
|
|
* represents a column. A short table definition might look like this:
|
|
*
|
|
* ```js
|
|
* class MyModel extends Model {}
|
|
* MyModel.init({
|
|
* columnA: {

|
|
* validate: {
|
|
* is: ["[a-z]",'i'], // will only allow letters
|
|
* max: 23, // only allow values <= 23
|
|
* isIn: {
|
|
* args: [['en', 'zh']],
|
|
* msg: "Must be English or Chinese"
|
|
* }
|
|
* },
|
|
* field: 'column_a'
|
|
* // Other attributes here
|
|
* },
|
|
* columnB: Sequelize.STRING,
|
|
* columnC: 'MY VERY OWN COLUMN TYPE'
|

*
|
|
* sequelize.models.modelName // The model will now be available in models under the name given to define
|
|
* ```
|
|
*
|
|
* As shown above, column definitions can be either strings, a reference to one of the datatypes that are
|
|
* predefined on the Sequelize constructor, or an object that allows you to specify both the type of the
|
|
* column, and other attributes such as default values, foreign key constraints and custom setters and
