31 Persistence Features

32 GORM API 22

33 GORM API 22

34 GORM API Plugins should not assume Hibernate! 22

35 GORM Plugins Redis - MongoDB - Amazon SimpleDB - Neo4j - Riak - GORM JPA - Hibernate

36 Where Queries New, compile-time checked query DSL Uses native Groovy operators ==,!=, >, <, <=, >= etc Aggregate functions supported avg, sum, max, min etc. 24

37 Where Queries New, compile-time checked query DSL def query = Person.where { firstname == "Bart" } Person bart = query.find() Uses native Groovy operators ==,!=, >, <, <=, >= etc Aggregate functions supported avg, sum, max, min etc. 24

38 Where Queries New, compile-time checked query DSL def query = Person.where { firstname == "Bart" } Person bart = query.find() Uses native Groovy operators ==,!=, >, <, <=, >= etc def query = Person.where { firstname == "Fred" &&!(lastname == 'Simpson') } Aggregate functions supported avg, sum, max, min etc. 24

39 Where Queries New, compile-time checked query DSL def query = Person.where { firstname == "Bart" } Person bart = query.find() Uses native Groovy operators ==,!=, >, <, <=, >= etc def query = Person.where { firstname == "Fred" &&!(lastname == 'Simpson') } Aggregate functions supported avg, sum, max, min etc. def query = Person.where { age > avg(age) } 24

40 Multiple Data Sources Support for defining multiple scoped data sources Each data source accessible via static property 25

41 Multiple Data Sources Support for defining multiple scoped data sources class ZipCode { String code static mapping = { datasource 'auditing' } } Each data source accessible via static property 25

42 Multiple Data Sources Support for defining multiple scoped data sources class ZipCode { String code static mapping = { datasource 'auditing' } } Each data source accessible via static property def zipcode = ZipCode.auditing.get(42) 25

43 Other GORM Improvements 26

44 Other GORM Improvements Abstract base domain classes These now result in a table 26

45 Other GORM Improvements Abstract base domain classes These now result in a table findorcreatewhere() 26

46 Other GORM Improvements Abstract base domain classes These now result in a table findorcreatewhere() findorsavewhere() 26

47 Other GORM Improvements Abstract base domain classes These now result in a table findorcreatewhere() findorsavewhere() def user = User.findByLogin('admin') if (!user) { } user = new User(login: 'admin') user.save(failonerror: true) def user = User.findOrSaveWhere(login: 'admin') 26

48 Better Unit Testing

49 Unit Testing 1.x 28

50 Unit Testing 1.x mockdomain() had only partial GORM support always lagged changes in GORM 28

51 Unit Testing 1.x mockdomain() had only partial GORM support always lagged changes in GORM Inheritance-based hierarchy duplicated for Spock difficult to extend 28

52 Unit Testing 1.x mockdomain() had only partial GORM support always lagged changes in GORM Inheritance-based hierarchy duplicated for Spock difficult to extend Weak support for web-related testing controllers tag libraries 28

53 The class MyControllerUnitTests { void setup() { new Person(...).save() new Person(...).save() } } void testindex() { def model = this.controller.index()... } 29

54 Spockified class MyControllerUnitTests extends Specification { void loadpeople() { new Person(...).save() new Person(...).save() } } def 'Test index action'() { given: 'Some people' loadpeople() when: 'The index action is called' def model = this.controller.index() then: 'The people variable is in the model' model.people!= null } 30

55 In-Memory GORM Full GORM implementation against ConcurrentHashMap Based on GORM for NoSQL codebase Support for Criteria queries Where queries Dynamic finders Detached criteria 31
