If there is no metadata for the field, or the item class does not support field metadata, an empty object is returned. Field metadata is taken from different sources, depending on the item type: * scrapy.item.Item: corresponding scrapy.item.Field object * dataclass items: "metadata" attribute for the corresponding field * attrs items: "metadata" attribute for the corresponding field * pydantic models: corresponding pydantic.field.FieldInfo/ModelField object The returned value is an instance of types.MappingProxyType, i.e. a dynamic read-only view of the original mapping, which gets automatically updated if the original mapping changes. r)fieldsz does not support field: ) fields_dictz is not a valid item class)r!rrrOrrnamer9KeyError__name__rrrPr"r<dict TypeError)rMr$rOr:rPs rget_field_meta_from_classrVvs*68899H 1* =>>> z " "H&&&&&&VJ'' & &EzZ''~%%%(*:M:M:MzzZ[[[  $ $H$$$$$$ `;z**:6? ? ` ` `j>Q>Q>QS]S]^__ _ ` J ' 'H `/ JGG G ` ` `j>Q>Q>QS]S]^__ _ ` J % %H###***FGGGsB33$C*C::$DN)typesrtypingrtuplerboolrrr"strr<rBrDrFrHrLr@rVrr=rr\s"""""" '% ' ' ' ')s)t))))&C&D&&&&&S&c&FV&&&&<3>4>>>>       $$$$$$&H$&HC&HDT&H&H&H&H&H&Hr=
