Class DS.RESTSerializer
Normally, applications will use the RESTSerializer
by implementing
the normalize
method and individual normalizations under
normalizeHash
.
This allows you to do whatever kind of munging you need, and is especially useful if your server is inconsistent and you need to do munging differently for many different kinds of responses.
See the normalize
documentation for more information.
Across the Board Normalization
There are also a number of hooks that you might find useful to define across-the-board rules for your payload. These rules will be useful if your server is consistent, or if you're building an adapter for an infrastructure service, like Parse, and want to encode service conventions.
For example, if all of your keys are underscored and all-caps, but otherwise consistent with the names you use in your models, you can implement across-the-board rules for how to convert an attribute name in your model to a key in your JSON.
import DS from 'ember-data';
export default DS.RESTSerializer.extend({
keyForAttribute: function(attr, method) {
return Ember.String.underscore(attr).toUpperCase();
}
});
You can also implement keyForRelationship
, which takes the name
of the relationship as the first parameter, the kind of
relationship (hasMany
or belongsTo
) as the second parameter, and
the method (serialize
or deserialize
) as the third parameter.
attrs
Inherited from DS.JSONSerializer packages/ember-data/lib/serializers/json-serializer.js:101
The attrs
object can be used to declare a simple mapping between
property names on DS.Model
records and payload keys in the
serialized JSON object representing the record. An object with the
property key
can also be used to designate the attribute's key on
the response payload.
Example
import DS from 'ember-data';
export default DS.Model.extend({
firstName: DS.attr('string'),
lastName: DS.attr('string'),
occupation: DS.attr('string'),
admin: DS.attr('boolean')
});
import DS from 'ember-data';
export default DS.JSONSerializer.extend({
attrs: {
admin: 'is_admin',
occupation: { key: 'career' }
}
});
You can also remove attributes by setting the serialize
key to
false in your mapping object.
Example
import DS from 'ember-data';
export default DS.JSONSerializer.extend({
attrs: {
admin: {serialize: false},
occupation: { key: 'career' }
}
});
When serialized:
{
"firstName": "Harry",
"lastName": "Houdini",
"career": "magician"
}
Note that the admin
is now not included in the payload.
primaryKey
Inherited from DS.JSONSerializer packages/ember-data/lib/serializers/json-serializer.js:77
The primaryKey is used when serializing and deserializing
data. Ember Data always uses the id
property to store the id of
the record. The external source may not always follow this
convention. In these cases it is useful to override the
primaryKey property to match the primaryKey of your external
store.
Example
import DS from 'ember-data';
export default DS.JSONSerializer.extend({
primaryKey: '_id'
});
store public
Inherited from DS.Serializer packages/ember-data/lib/system/serializer.js:52
The store
property is the application's store
that contains all records.
It's injected as a service.
It can be used to push records from a non flat data structure server
response.
