次の例では、Product.searchAll が添加剤と製品の両方に一致することを期待していますが、無視されているようeq('name', taste)
です。
class Additive {
String flavor
static belongsTo = [product:Product]
}
class Product {
String name
static hasMany = [additives:Additive]
static constraints = {
name nullable:true
}
static namedQueries = {
searchAll { taste ->
or {
eq('name', taste)
additives { eq('flavor', taste) }
}
}
searchAdditives { taste ->
additives { eq('flavor', taste) }
}
searchProducts { taste ->
eq('name', taste)
}
}
}
class SearchSpec extends grails.plugin.spock.IntegrationSpec {
def choc, muff
def 'searchAll should return products and additives that match - THIS FAILS'() {
setup:
createTestProducts()
expect:
Product.searchAll("chocolate").list() == [choc, muff]
}
def 'searchProducts should return only products that match - THIS PASSES'() {
setup:
createTestProducts()
expect:
Product.searchProducts("chocolate").list() == [choc]
}
def 'searchAdditives should return only additives that match - THIS PASSES'() {
setup:
createTestProducts()
expect:
Product.searchAdditives("chocolate").list() == [muff]
}
private def createTestProducts() {
// create chocolate
choc = new Product(name:'chocolate').save(failOnError:true, flush:true)
// create a chocoloate-flavored muffin
muff = new Product(name:'muffin').addToAdditives(flavor:'chocolate').save(failOnError:true, flush:true)
}
}
生成される SQL は次のとおりです。
select this_.id as id1_1_, this_.version as version1_1_,
this_.name as name1_1_, additives_1_.id as id0_0_,
additives_1_.version as version0_0_, additives_1_.flavor as
flavor0_0_, additives_1_.product_id as product4_0_0_ from product
this_ inner join additive additives_1_ on
this_.id=additives_1_.product_id where (this_.name=? or
(additives_1_.flavor=?))
私の構文に問題がありますか、それとも Grails、GORM、または H2 の問題ですか?
