ember-solr

Ember Data adapter that connects to a Solr server.

The SolrAdapter currently provides the read methods on DS.Adapter like find and findQuery.

Installing ember-solr with Ember CLI

$ ember install:addon ember-solr

This will create a new setting in config/environment.js. Replace the default value with your Solr server.

Using SolrAdapter

$ ember generate solr-adapter application [--enableRealTimeGet] [--url=http://example.com/solr/]

This will make a subclass of SolrAdapter for you to configure and register it as the application adapter.

See SolrAdapter for properties and methods you can override.

long, double and BigNumber

ember-solr uses a custom JSON parsing library to handle Solr long and double fields without losing precision on values that exceed Number.MAX_SAFE_INTEGER (2^53 - 1).

These values will be automatically detected and represented as instances of BigNumber using a string to represent the complete value.

No support is provided for performing arithmetic computations on BigNumber, such as addition, subtraction or multiplication.

JSON-P Limitations

By default, SolrAdapter.dataType is set to 'jsonp' to work with Solr servers that do not have CORS headers enabled. If you want to use Optimistic Concurrency or use long or double fields in your schema, JSON-P will not be able to handle values that exceed JavaScript's Number.MAX_SAFE_INTEGER (2^53 - 1).

In particular, this limitation means that using Solr's built-in _version_ field for optimistic concurrency is not possible with JSON-P.

Customizing Serialization

$ ember generate solr-serializer <name> [--dynamic] [--atomic] [--multiValued]

This will generate a serializer for a given model with some options.

Flag	Description
dynamic	Includes DynamicSerializerMixin
atomic	Includes AtomicSerializerMixin
multiValued	Includes AtomicMultiValuedSerializerMixin

Custom attribute types

This adapter registers the following types that map to Solr field types

Solr field type	DS.attr type
text	string
double	BigNumber
float	number
int	number
long	BigNumber
strings	array of string
numbers	array of number
doubles	array of BigNumber
floats	array of number
ints	array of number
longs	array of BigNumber
booleans	array of boolean
dates	array of date

The plural array types are intended for use with Solr fields that are multiValued="true".

Configuration

config/environment.js sets the URL of the Solr server.

SolrAdapter has the following properties:

• baseURL usually injected from config/environment
• dataType (Default: jsonp) chooses normal json or jsonp to side-step cross origin restrictions
• defaultCore specify a Solr Core to route requests to by default
• defaultSerializer (Default: -solr)
• enableRealtimeGet (Default: false) use Solr's RealTimeGetHandler when applicable

SolrAdapter also has these methods that can be overridden:

• coreForType choose another Solr Core for a given type
• filterQueryForType create an optional filter query to filter documents
• handlerForType select a Solr request handler path and type for an operation
• uniqueKeyForType override the canonical id field with something else

Dynamic Fields

DynamicSerializerMixin provides a quick way to connect to a Solr server using Dynamic Fields.

Declare a model such as:

import DS from 'ember-data';

export default DS.Model.extend({
  title: DS.attr(),
  keywords: DS.attr('strings'),
  body: DS.attr('text'),
  popularity: DS.attr('float'),
  isPublic: DS.attr('boolean')
});

Then generate a serializer for your model:

ember g solr-serializer post --dynamic

The attributes on this model would be mapped, by default, to:

• title => title_s
• keywords => keywords_ss
• body => body_txt
• popularity: popularity_f
• isPublic: is_public_b

See DynamicSerializerMixin for more on how to customize dynamic field names.
