Support model ref and function ref

[LSafer]

Explanation

Mongoose allows the field ref to be any of:

• string
• model
• a function that returns string
• a function that returns model

Expected Behavior

When ref is a function, the plugin executes the function
When ref is a model, the plugin takes the name of the model

Actual Behavior

The plugin uses the toString function the value on ref to get the collection name

[LSafer]

    /**
     * The model that `populate()` should use if populating this path.
     */
    ref?: string | Model<any> | ((this: any, doc: any) => string | Model<any>);
