Reducers

The default reducer that you passed to the Redux store allows you to update your models based on Redux actions.

Model.reducer

Your model classes' static reducer function will automatically be called when a Redux action is dispatched. Override them to add your own behavior.

class Book extends Model {
    static reducer(action, Book, session) {
        let book;
        switch (action.type) {
        case 'CREATE_BOOK':
            Book.create(action.payload);
            break;
        case 'UPDATE_BOOK':
            book = Book.withId(action.payload.id);
            book.update(action.payload);
            break;
        case 'REMOVE_BOOK':
            book = Book.withId(action.payload);
            book.delete();
            break;
        case 'ADD_AUTHOR_TO_BOOK':
            book = Book.withId(action.payload.bookId);
            book.authors.add(action.payload.author);
            break;
        case 'REMOVE_AUTHOR_FROM_BOOK':
            book = Book.withId(action.payload.bookId);
            book.authors.remove(action.payload.authorId);
            break;
        case 'ASSIGN_PUBLISHER':
            book = Book.withId(action.payload.bookId);
            book.publisherId = action.payload.publisherId;
            break;
        }
        // Return value is ignored.
    }
}

Static methods

To find out which methods you can call on your model class take a look at the API reference. The most useful ones are as follows:

• create(props): creates a new Model instance with props. If you don't supply an id, the new id will be Math.max(...allOtherIds) + 1.
• upsert(props): either creates a new Model instance with props or, in case an instance with the same id already exists, updates that one - in other words it's create or update behaviour.
• withId(id): gets the Model instance with id id.
• get(matchObj): gets a Model instance based on matching properties in matchObj (if you are sure there is only one matching instance).

Instance methods

Once you have a model instance, you may want to call one of the following methods:

• update(mergeObj): merges mergeObj with the Model instance properties. Returns undefined.
• delete(): deletes the record for this Model instance in the database. Returns undefined.
