Can you help me please to consider where to place resource (service) specific business logic in AngularJS. I feel it should be great to create some model-like abstraction over my resource, but I'm not sure how.
API call:
> GET /customers/1
< {"first_name": "John", "last_name": "Doe", "created_at": '1342915200'}
Resource (in CoffeScript):
services = angular.module('billing.services', ['ngResource'])
services.factory('CustomerService', ['$resource', ($resource) ->
$resource('http://virtualmaster.apiary.io/customers/:id', {}, {
all: {method: 'GET', params: {}},
find: {method: 'GET', params: {}, isArray: true}
})
])
I'd like to do something like:
c = CustomerService.get(1)
c.full_name()
=> "John Doe"
c.months_since_creation()
=> '1 month'
Thanks a lot for any ideas. Adam
The best place for logic that needs to be invoked on an instance of a domain object would be a prototype of this domain object.
You could write something along those lines:
services.factory('CustomerService', ['$resource', function($resource) {
var CustomerService = $resource('http://virtualmaster.apiary.io/customers/:id', {}, {
all: {
method: 'GET',
params: {}
}
//more custom resources methods go here....
});
CustomerService.prototype.fullName = function(){
return this.first_name + ' ' + this.last_name;
};
//more prototype methods go here....
return CustomerService;
}]);
You might want to take a look at my answer to this SO question on related topic.
With such a solution, domain specific logic goes into custom domain entity class (in particular, its prototype).
