In #1298, the spec/doc for polymorphic relations was reviewed
**hasX relation**
- `type`: **hasMany**
- `as`: redefines **this** relation's name (optional)
- `model`: **modelTo**
- `polymorphic`:
- typeOf `polymorphic` === `String`
- matching **belongsTo** relation name
- `foreignKey` is generated as `polymorphic + 'Id'`,
- `discriminator` is generated as `polymorphic + 'Type'`
- typeOf `polymorphic` === `Object`
- `as`: **DEPRECATED** should display a warning,
replaced by `selector`
- `selector`: should match **belongsTo** relation name if the
latter is defined with {polymorphic: true}
- (required) if both foreignKey and discriminator
are **NOT** provided
- (extraneous) if both foreignKey and discriminator
are provided
- `foreignKey`: A property of modelTo, representing the fk to
modelFrom's id.
- generated by default as `selector + 'Id'`
- `discriminator`: A property of modelTo, representing the actual
modelFrom to be looked up and defined
dynamically
- generated by default as `selector + 'Type'`
---
**belongsTo relation**
- `type`: **belongsTo**
- `as`: redefines **this** relation's name (optional)
- `model`: **NOT EXPECTED**: should throw an error at
relation validation
- `polymorphic`:
- typeOf `polymorphic` === `Boolean`
- `foreignKey` is generated as `relationName + 'Id'`,
- `discriminator` is generated as `relationName + 'Type'`
- typeOf `polymorphic` === `Object`
- `as`: **DEPRECATED**: should display a warning,
replaced by `selector`
- `selector`:
- (required) if both foreignKey and discriminator
are **NOT** provided
- (extraneous) if both foreignKey and discriminator
are provided
- `foreignKey`: A property of modelTo, representing the fk to
modelFrom's id.
- generated by default as `selector + 'Id'`
- `discriminator`: A property of modelTo, representing the actual
modelFrom to be looked up and defined
dynamically
- generated by default as `selector + 'Type'`
The PR superseeds the existing deepMerge algorithm used to merge
settings of parent and child models with a new algorithm that allows
to specify the way each setting is merged or mixed-in.
This configuration of this algorithm uses a merge policy specification.
The `getMergePolicy()` helper of BaseModelClass can be used to ease
model merge configuration.
Next is presented the expected merge behaviour for each option.
NOTE: This applies to top-level settings properties
- Any
- `{replace: true}` (default): child replaces the value from parent
- assignin `null` on child setting deletes the inherited setting
- Arrays
- `{replace: false}`: unique elements of parent and child cumulate
- `{rank: true}` adds the model inheritance rank to array
elements of type Object {} as internal property `__rank`
- Object {}:
- `{replace: false}`: deep merges parent and child objects
- `{patch: true}`: child replaces inner properties from parent
The recommended merge policy is returned by getMergePolicy()
when calling the method with option `{configureModelMerge: true}`.
The legacy built-in merge policy is returned by `getMergePolicy()`
when avoiding option `configureModelMerge`.
NOTE: it also delivers ACLs ranking in addition to the legacy
behaviour as well as fixes for settings `description` and `relations`
`getMergePolicy()` can be customized using model's setting
`configureModelMerge` as follows:
```
{
// ..
options: {
configureModelMerge: {
// merge options
}
}
// ..
}
```
`getMergePolicy()` method can also be extended programmatically as
follows:
```
myModel.getMergePolicy = function(options) {
const origin = myModel.base.getMergePolicy(options);
return Object.assign({}, origin, {
// new/overriding options
});
};

New type that preserves string input as a string, but ensures that
the string is a valid Date.
Additionally, provides a .toDate function to provide the Date
object representation of the string.
Some databases are storing the value in UTC (not ISO) format,
and truncating the values. Even though this is technically
unavoidable, it does fail strict string equality.
