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
});
};
