One-to-one relations
It's possible to create one-to-one relations in schema. Those relations will be then available for querying via GraphQL.
Define relations in schema
To define one-to-one relation nested entity must have id
field that is either String!
or ID!
. In parent entity create field (with any name) that is of nested entity's type (can be nullable or required).
type Space {
id: String!
name: String
}
type Proposal {
id: String!
name: String
space: Space!
}
Create entities in writer
When creating entities in writer set Proposal
's space
field to the value of Space
's id
field.
const proposal = new Proposal('proposal_id');
proposal.name = 'Proposal name';
proposal.space = 'Space_id';
await proposal.save();
Query data via GraphQL
It's now possible to nest space entity when querying proposals. You can still filter proposals by space (limited to Space
's id
currently).
{
proposals(first: 10, where: { space: "0x00b60f2a154b9aaec8e4bec8e04f86d6cd92a9c993871e904bd815962603492d" }) {
id
space {
id
name
}
}
}
