@baseView

A base view definition requires a single @baseView type directives.

Example

type UserStatistics @baseView(sqlFile: "./userStatistics.sql") {
    name: String! @index
    numberOfUsers: Int!
}

The only object directives that are allowed for base views are @baseView, @permission and @filterByJwtData. The only allowed field directives are @index and @permission.

You can reference other projections (and CRUD types) in your base view schema. The GraphQL API will automatically fetch all referenced data.

Arguments

You can use the following arguments on the @baseView directive directly:

Argument sqlFile

The path in the sqlFile argument has to be relative.

SELECT name AS name, COUNT(1) AS numberOfUsers FROM userView GROUP BY name

Reporting is an advanced topic. You need to understand the structure of your data on a relatively deep level. Therefore we let you create your reports by working directly on your data in your database:

• Every projection has a corresponding view that is named like the projection and suffixed by view. You can use this view to create your advanced view.
• Each selected column is required to have an alias that matches the name of the field in the schema.
• References to other projections (and CRUD types) can be done by selecting the id of the referenced projection. In case of array references you can use the jsonb_agg function to aggregate the ids: SELECT jsonb_agg(id) AS userList FROM user;

File as field type

You can use files as field types. When using the GraphQL API to fetch the view data, the result will be the ID of the file.

You can query the CRUD GraphQL API to get more detailed file information like the mimeType or the size.
