# angular-most
Most Web Framework Client Module for Angular JS
## Installation
npm install angular-most
or:
bower install angular-most
### Usage under AngularJS:
Load the following scripts:
and use $context angular service:
angular.module("app",["most"])
.controller("OrderController", function($context) {
$context.model("Order")
.where("orderStatus")
.equal(1)
.orderBy("orderedDate")
.take(10)
.getItems().then(function(result) {
//enumerate items
}).catch(function(err) {
console.log(err);
});
});
### Authentication
Use basic authentication (node.js, jQuery and AngularJS environment):
context.authenticate("[email protected]","user").then(function() {
//
}).catch(function(err) {
console.log(err);
});
Use cookie based authentication (node.js environment):
//get cookie from request
context.getService().setCookie(request.headers.cookie);
### ClientDataContext Class
#### model(name)
Gets an instance of ClientDataModel class based on the given name.
context.model("Order").where("orderStatus").equal(1).getItems().then(function(result) {
//
}).catch(function(err) {
console.log(err);
});
#### getService()
Gets the instance of ClientDataService associated with this data context.
console.log(context.getService().getBase());
#### setService(service)
Associates the given ClientDataService instance with this data context.
context.setService(new MyDataService("http://data.example.com"));
### ClientDataModel Class
#### asQueryable()
Returns an instance of ClientDataQueryable class associated with this model.
$context.model("Order")
.asQueryable()
.select("id","customer/description as customerDescription", "orderDate", "orderedItem/name as orderedItemName")
.where("paymentMethod/alternateName").equal("DirectDebit")
.orderByDescending("orderDate")
.take(10)
.getItems()
.then(function (result) {
//
}).catch(function (err) {
console.log(err);
});
#### getName()
Gets a string which represents the name of this data model.
#### getService()
Gets the instance of ClientDataService associated with this data model.
#### remove(obj)
Removes the given item or array of items.
var order = {
id:1
};
context.model("Order").remove(order).then(function(result) {
//
}).catch(function(err) {
console.log(err);
}
#### save(obj)
Creates or updates the given item or array of items.
var order = {
id:1,
orderStatus:7
};
context.model("Order").save(order).then(function(result) {
//
}).catch(function(err) {
console.log(err);
}
#### schema()
Returns the JSON schema of this data model.
context.model("Order").schema().then(function(result) {
result.attributes.forEach(function(x) {
console.log(x.name);
});
}).catch(function(err) {
console.log(err);
}
#### select(...attr)
Initializes and returns an instance of ClientDataQueryable class by selecting an attribute or a collection of attributes.
$context.model("Order")
.select("id","customer","orderedItem","orderStatus")
.orderBy("orderDate")
.take(25)
.getItems()
.then(function (result) {
//
}).catch(function (err) {
console.log(err);
});
#### skip(num)
Initializes and returns an instance of ClientDataQueryable class by specifying the number of records to be skipped.
$context.model("Order")
.skip(10)
.take(10)
.getItems()
.then(function (result) {
//
}).catch(function (err) {
console.log(err);
});
#### take(num)

.take(10)
.getItems()
.then(function (result) {
//
}).catch(function (err) {
console.log(err);
});
#### where(attr)
Initializes a comparison expression by using the given attribute as left operand
and returns an instance of ClientDataQueryable class.
$context.model("Order")
.where("orderedItem/category").equal("Laptops")
.take(10)
.getItems()
.then(function (result) {
//
}).catch(function (err) {
console.log(err);
});
### ClientDataQueryable Class
ClientDataQueryable class enables developers to perform simple and extended queries against data models.
The ClienDataQueryable class follows [DataQueryable](https://docs.themost.io/most-data/DataQueryable.html)
which is introduced by [MOST Web Framework ORM server-side module](https://github.com/kbarbounakis/most-data).
