        )
    }
)
Parameters:

  • name (str) –

  • interface_types (Optional[Sequence[InterfaceType]]) – (experimental) The Interface Types this Object Type implements. Default: - no interface types

  • definition (Mapping[str, IField]) – (experimental) the attributes of this type.

  • directives (Optional[Sequence[Directive]]) – (experimental) the directives for this object type. Default: - no directives

Methods

add_field(*, field=None, field_name=None)

(experimental) Add a field to this Object Type.

Object Types must have both fieldName and field options.

Parameters:

  • field (Optional[IField]) – (experimental) The resolvable field to add. This option must be configured for Object, Interface, Input and Union Types. Default: - no IField

  • field_name (Optional[str]) – (experimental) The name of the field. This option must be configured for Object, Interface, Input and Enum Types. Default: - no fieldName

Return type:

None

attribute(*, is_list=None, is_required=None, is_required_list=None)

(experimental) Create a GraphQL Type representing this Intermediate Type.

Parameters:

  • is_list (Optional[bool]) – (experimental) property determining if this attribute is a list i.e. if true, attribute would be [Type]. Default: - false

  • is_required (Optional[bool]) – (experimental) property determining if this attribute is non-nullable i.e. if true, attribute would be Type! Default: - false

  • is_required_list (Optional[bool]) – (experimental) property determining if this attribute is a non-nullable list i.e. if true, attribute would be [ Type ]! or if isRequired true, attribe would be [ Type! ]! Default: - false
