Trying to build relations using this guide
http://docs.doctrine-project.org/projects/doctrine-orm/en/latest/tutorials/composite-primary-keys.html
Here is my entities mappings:
# Simple entity with no foreign keys
Region:
id:
id: { type: bigint, id: true,
generator: { strategy: IDENTITY } }
fields:
# some fields
# Domain has 1-to-1 relation to region, and Region#id used as Domain
identifier
Domain:
id:
Region: { associationKey: true }
fields:
# some fields
oneToOne:
Region:
targetEntity: Region
joinColumn: { name: departure_city_id,
referencedColumnName: id }
# Then I want to create many-to-many relation between Domain and Region
(this is logistic information about what Regions are available for each
Domain)
# As described in guide "Use-Case 3: Join-Table with Metadata"
DomainRegion:
id:
Domain: { associationKey: true }
Region: { associationKey: true }
fields:
# some fields
manyToOne:
Domain:
targetEntity: Domain
#inversedBy: DomainRegions
joinColumn: { name: domain_id,
referencedColumnName: departure_city_id }
Region:
targetEntity: Region
#inversedBy: DomainRegions
joinColumn: { name: region_id,
referencedColumnName: id }
lifecycleCallbacks: { }
This mappings had no errors during entities generation and even used in
code. The only thing than troubles me - is validation, then I call validate
command, i get messages like this:
** Cannot map association 'DomainRegion#Domain as identifier, because the
target entity 'Domain' also maps an association as identifier.*
It looks for me as mapping issue, otherwise tell me where I was wrong.
