how to serve different schemas based on user

[alexrohleder]

hey,

I have a relational database that I want to expose via GraphQL.

An item will have attributes, everything is scoped for a user. The tables looks like items -> items_to_attributes -> attributes.

I wonder if I can dynamically generate the schema based on creation, update or deletion of attributes, for each user.

For example:

• user1 has attr1, attr2
• user2 has attr3, attr4, attr5

I want them to be able to query like this:

• user1 query { item { attr1, attr2 } }
• user2 query { item { attr3, attr4, attr5 } }

thanks in advance :)

We don't support dynamic schemas. There's a lot of complexity there around how plugins, reporting, etc would deal with a dynamic schema. See eg #5071 (comment)

For what it's worth, having a super dynamic schema will make it challenging to do things like code generation, which is one of the main strengths of GraphQL.

thanks for the explanation and the code generation example :) @glasser

I ended up using aliases to name several attributes:

query {
  item {
    attr1: attr(id: 1)
    attr2: attr(id: 2)
  }
}
