You can choose to remove any fields from objects, interfaces and input object types, +doing this will ensure that these fields are not exposed for the role and they will not +be able to query the fields that have been hidden. + +For example, let's say we have the following remote schema added to the +graphql-engine: + +.. code-block:: graphql + + type User { + id ID! + first_name String! + last_name String! + phone String! + email String! + } + + type Query { + user(id: ID!) : User + get_users_by_name (first_name: String!, last_name:String): [User] + } + +Now, we want to expose only certain fields of the ``User`` object for the +``public`` role here. The ``public`` role should not be allowed to access +the ``id``, ``email`` and ``phone`` fields of the ``User`` object. Now, since +the ``public`` role doesn't have access to the ``id`` field of the ``User`` object and +let's say that the ``id`` argument of the ``user`` field defined in the ``Query`` object +is the same as the ``id`` field of the ``User`` object, there will be no way of exposing the +``user`` field in the ``Query`` object, so we'll remove that field as well. + +We can accomplish this by specifying the restricted schema (in GraphQL IDL format) for the +``public`` role. In the above case, it will be: + +.. code-block:: graphql + + type User { + first_name String! + last_name String! + } + + type Query { + get_users_by_name (first_name: String!, last_name: String): [User] + } + +We use the above schema document to configure the remote schema permissions for the ``public`` +role by using the :ref:`add_remote_schema_permissions` API. + +You can modify different `GraphQL Types `__ in the following manner: + +1. Scalar - A scalar definition cannot be modified differently from its correponding remote schema scalar definition. +2. Object - An object can omit some of the fields from its definition. +3. Interface - An interface, like the object type, can omit some of the fields from its definition. +4. Union - A union can be modified to only support a subset of the ``possibleTypes`` of its original union definition. +5. Enum - An enum can be configured to omit some enum values from its definition. +6. Input object - An input object, just like object type, can omit some of the (input) fields from its definition. + +In a `field definition `__ the arguments can +be configured to only expose a subset of the arguments defined. + +For example, let's consider the remote schema used in the example above, but in this case we +want the ``public`` role to use the ``get_user_by_name`` with only the ``first_name`` +argument and the ``public`` role should not be able to access the ``last_name`` argument. +The schema should look like: + +.. code-block:: graphql + + type User { + first_name String! + last_name String! + } + + type Query { + get_users_by_name (first_name: String!): [User] + } + +Argument presets +---------------- + +The role-based schema only helps in changing the type definitions that are exposed. Argument +presets are used to constrain the input values in fields. + +Argument presets automatically inject values from session variables or static values during execution. +Arguments which are preset will not be exposed in the schema. +Argument presets are set on an argument value using the ``@preset`` directive. + +.. note:: + + A preset value can be defined only at the ``INPUT_FIELD_DEFINITION`` and ``ARGUMENT_DEFINITION`` + system directive locations i.e. only at an input object field or an argument field. + +For example, let's say we have the following remote schema added to the +graphql-engine: + +.. code-block:: graphql + + type User { + id ID! + first_name String! + last_name String! + phone String! + email String! + } + + type Activity { + name String! + activity_type String! + created_at String! + } + + type Query { + get_user(id: ID!) : User + get_user_activities(user_id: ID!, limit: Int!): [Activity] + } + +We want to configure the ``user`` role to only be able to query their +own record. To do this, we need to preset the ``id`` parameter of the ``get_user`` +field defined in the ``Query`` object. Let's say we have the value of the ``id`` +argument set in one of the :ref:`session variables `, we can +preset the ``id`` argument with the session variable. Using the above schema, +we can do that in the following manner: + +.. code-block:: graphql + + type Query { + get_user(id: ID! @preset(value: "x-hasura-user-id")) : User + get_user_activities(user_id: ID!, limit: Int!) + } + +Configuring the remote schema for the ``user`` role with the above schema +will remove the ``id`` argument from the schema and the value of the ``id`` +argument will get injected via the ``x-hasura-user-id`` session variable, whenever the +``user`` role executes a query containing the ``get_user`` field. + +Preset values can also be static values. + +For example: + +Suppose, we want the ``user`` role to allow to only get 10 of the user activities using the +``get_user_activities`` field, we can do that by setting a ``preset`` value for the +``limit`` argument of the ``get_user_activities`` to 10. The schema implementing +this change should look like: + +.. code-block:: graphql + + type Query { + get_user(id: ID! @preset(value: "x-hasura-user-id")) : User + get_user_activities(user_id: ID!, limit: Int! @preset(value: 10)) : [Activity] + } + +.. note:: + + By default, any preset string value in the format of ``x-hasura-*`` is assumed + to be a :ref:`session variable `. To override this + behaviour i.e. to treat the value literally, the ``static`` argument equal to ``true`` + needs to be added in the ``preset`` directive. In the following example, + the ``x-hasura-user-id`` will be treated literally. + + .. code-block:: graphql + + get_user(id: ID! @preset(value: "x-hasura-user-id", static: true)) : User + +Input object field presets +^^^^^^^^^^^^^^^^^^^^^^^^^^ + +Input object fields can also have preset values set.

After `IntCompareObj` is parsed, the `MessageWhereInpObj` +-- will continue parsing the `id` field and then it sees that the `IntCompareObj` +-- has a preset associated with it, so now the preset of `IntCompareObj` will be +-- associated with `id`. A new preset map pertinent to `MessageWhereInpObj` will +-- be created, which will be `{id: {eq: 2}}`.

Presets can be set using the `preset` +directive, the preset directive is defined in the following manner: + +``` +scalar PresetValue + +directive @preset( + value: PresetValue +) on INPUT_FIELD_DEFINITION | ARGUMENT_DEFINITION +``` + +When a preset directive is defined on an input type, the input type is removed +from the schema and the value is injected by the graphql-engine during the +execution. + +There are two types of preset: + +1. Static preset +---------------- + +Static preset is used to preset a static GraphQL value which will be injected +during the execution of the query. Static presets can be specified on all types +of input types i.e scalars, enums and input objects and lists of these types. +The preset value (if specified) will be validated against the type it's provided. +For example: + +``` +users(user_id: Int @preset(value: {user_id: 1})) +``` + +The above example will throw an error because the preset is attempting to preset +an input object value for a scalar (Int) type. + +2. Session variable preset +-------------------------- + +Session variable preset is used to inject value from a session variable into the +graphql query during the execution. If the `value` argument of the preset directive +is in the format of the session variable i.e. `x-hasura-*` it will be treated as a +session variable preset. During the execution of a query, which has a session variable +preset set, the session variable's will be looked up and the value will be constructed +into a GraphQL variable. Check out `resolveRemoteVariable` for more details about how +the session variable presets get resolved. + +At the time of writing this note, session variable presets can **only** be specified at +named types and only for scalar and enum types. This is done because currently there's +no good way to specify array or object values through session variables. +-} + +{- Note [Remote Schema Permissions Architecture] +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The Remote schema permissions feature is designed in the following way: + +1. An user can configure remote schema permissions for a particular role using + the `add_remote_schema_permissions` API, note that this API will only work + when remote schema permissions are enabled while starting the graphql-engine, + which can be done either by the setting the server flag + `--enable-remote-schema-permissions` or the env variable + `HASURA_GRAPHQL_ENABLE_REMOTE_SCHEMA_PERMISSIONS` to `true`. Check the module + documentation of `Hasura.RQL.DDL.RemoteSchema.Permission` (this module) for + more details about how the `add_remote_schema_permissions` API works. +2. The given schema document is parsed into an `IntrospectionResult` object, +3. The schema is built with the `IntrospectionResult` parsed in #2 for the said role. + Check out the documentation in `argumentsParser` to know more about how the presets + are handled. +4. For a remote schema query, the schema will return a `RemoteField` which + contains unresolved session variables, the `RemoteField` is resolved using the + `resolveRemoteField` function. The `resolveRemoteVariable` function contains more + details about how the `RemoteVariable` is resolved. +5. After resolving the remote field, the remote server is queried with the resolved + remote field. +-} + +showRoleBasedSchemaValidationError :: RoleBasedSchemaValidationError -> Text +showRoleBasedSchemaValidationError = \case + NonMatchingType fldName fldType expectedType providedType -> + "expected type of " <> dquote fldName <> "(" <> dquote fldType <> ")" <>" to be " <> + (G.showGT expectedType) <> " but recieved " <> (G.showGT providedType) + TypeDoesNotExist graphQLType typeName -> + graphQLType <<> ": " <> typeName <<> " does not exist in the upstream remote schema" + NonMatchingDefaultValue inpObjName inpValName expectedVal providedVal -> + "expected default value of input value: " <> inpValName <<> "of input object " + <> inpObjName <<> " to be " <> defaultValueToText expectedVal <> " but recieved " + <> defaultValueToText providedVal + NonExistingInputArgument inpObjName inpArgName -> + "input argument " <> inpArgName <<> " does not exist in the input object:" <>> inpObjName + MissingNonNullableArguments fieldName nonNullableArgs -> + "field: " <> fieldName <<> " expects the following non nullable arguments to " + <> "be present: " <> englishList "and" (fmap dquote nonNullableArgs) + NonExistingDirectiveArgument parentName parentType directiveName nonExistingArgs -> + "the following directive argument(s) defined in the directive: " + <> directiveName + <<> " defined with the type name: " + <> parentName <<> " of type " + <> parentType <<> " do not exist in the corresponding upstream directive: " + <> englishList "and" (fmap dquote nonExistingArgs) + NonExistingField (fldDefnType, parentTypeName) providedName -> + "field " <> providedName <<> " does not exist in the " + <> fldDefnType <<> ": " <>> parentTypeName + NonExistingUnionMemberTypes unionName nonExistingMembers -> + "union " <> unionName <<> " contains members which do not exist in the members" + <> " of the remote schema union :" + <> englishList "and" (fmap dquote nonExistingMembers) + CustomInterfacesNotAllowed objName customInterfaces -> + "custom interfaces are not supported.
