Model.hasChanged method
Expectations:
it('should tell if the model has any change', () => {
let employee = new Employee();
expect(employee.hasChanged()).toBe(false);
employee.name = 'Bob';
expect(employee.hasChanged()).toBe(true);
});
it('should tell if a specific field has any change', () => {
let employee = new Employee();
expect(employee.hasChanged('name')).toBe(false);
employee.id = 123;
expect(employee.hasChanged('name')).toBe(false);
employee.name = 'Bob';
expect(employee.hasChanged('name')).toBe(true);
employee.name = '';
expect(employee.hasChanged('name')).toBe(true);
});Model.where method
Implement a Model.where method:
Employee.where({firstName: 'John'})
.then((employees: Array<Employee>) => {
// do something
});Produces:
GET /api/employees?firstName: 'John'
Model.fetch method added
Employee.find(123).then((employee) => { /* */ });
// or
new Employee({id: 123}).fetch();hasMany Model association
Expectation:
const Employee = Dougal.Model.extends(function () { });
const Office = Dougal.Model.extends(function () {
this.hasMany('employees', Employee);
});
Office.find(1).employees.then((employees) => { /* do something */ });belongsTo Model association
Expectations:
const Office = Dougal.Model.extends(function () {
this.urlRoot = '/offices';
});
const Employee = Dougal.Model.extends(function () {
this.urlRoot = '/employees';
this.belongsTo('office', Office);
});
Employee.find(123).office.then((office) => { /* do something */ });By default, it creates (if not already present) a officeId attribute.
Fix – Model.fetch should mark the model as unchanged
Example:
let employee = new Employee();
employee.id = id;
employee.fetch();Expectation: model.hasChanged() should return false, not true, since the model was just synced up.
