Unfortunately other approaches (eg. return a partial of a function that builds the arguments) is slow, hence this laborious way of doing things. It's done like this so validators don't all need **kwargs in their signature, eg. any combination of the arguments "values", "fields" and/or "config" are permitted. r rr c s$ g | ] }|� j � j�� B kr|�qS r# )r{ �keywordsrg )r6 �k�rH r# r$ � <listcomp> s �z*make_generic_validator.<locals>.<listcomp>r" � Invalid signature for validator rt z�, "self" not permitted as first argument, should be: (cls, value, values, config, field), "values", "config" and "field" are all optional.�cls� N)rv rs r4 r r rw rx rg r �popr r �_generic_validator_clsre �_generic_validator_basic)rH rs rz r{ Z first_argr# r� r$ �make_generic_validator� s � � r� �ValidatorsList)�v_funcsr3 c C s dd� | D �S )Nc S s g | ]}|rt |��qS r# )r� rc r# r# r$ r� s z#prep_validators.<locals>.<listcomp>r# )r� r# r# r$ �prep_validators s r� �valuesr7 �configr+ )rH rz r{ r3 c s� d}d|krd}|dh8 }|� t�s:td� � d|� d���|rJ� fdd�S |t� kr`� fd d�S |d hkrv� fd d�S |d hkr�� fd d�S |dhkr�� fdd�S |d d hkr�� fdd�S |d dhkr҇ fdd�S |d dhkr� fdd�S � fdd�S d S )NF�kwargsTr� rt zb, should be: (cls, value, values, config, field), "values", "config" and "field" are all optional.c s � | ||||d�S �N)r� r7 r� r# �r� r_ r� r7 r� r� r# r$ �<lambda>. � z(_generic_validator_cls.<locals>.<lambda>c s � | |�S r! r# r� r� r# r$ r� 0 r� r� c s � | ||d�S �N)r� r# r� r� r# r$ r� 2 r� r7 c s � | ||d�S �N)r7 r# r� r� r# r$ r� 4 r� r� c s � | ||d�S �N)r� r# r� r� r# r$ r� 6 r� c s � | |||d�S �N)r� r7 r# r� r� r# r$ r� 8 r� c s � | |||d�S �N)r� r� r# r� r� r# r$ r� : r� c s � | |||d�S �N)r7 r� r# r� r� r# r$ r� < r� c s � | ||||d�S r� r# r� r� r# r$ r� ? r� ��issubset� all_kwargsr re �rH rz r{ Z has_kwargsr# r� r$ r� s2 � r� c s� d}d|krd}|dh8 }|� t�s:td� � d|� d���|rJ� fdd�S |t� kr`� fd d�S |d hkrv� fd d�S |d hkr�� fd d�S |dhkr�� fdd�S |d d hkr�� fdd�S |d dhkr҇ fdd�S |d dhkr� fdd�S � fdd�S d S )NFr� Tr� rt z], should be: (value, values, config, field), "values", "config" and "field" are all optional.c s � ||||d�S r� r# r� r� r# r$ r� O r� z*_generic_validator_basic.<locals>.<lambda>c s � |�S r! r# r� r� r# r$ r� Q r� r� c s � ||d�S r� r# r� r� r# r$ r� S r� r7 c s � ||d�S r� r# r� r� r# r$ r� U r� r� c s � ||d�S r� r# r� r� r# r$ r� W r� c s � |||d�S r� r# r� r� r# r$ r� Y r� c s � |||d�S r� r# r� r� r# r$ r� [ r� c s � |||d�S r� r# r� r� r# r$ r� ] r� c s � ||||d�S r� r# r� r� r# r$ r� ` r� r� r� r# r� r$ r� B s2 � r� r. )�type_r3 c C s& t dd� | jD �� }dd� |�� D �S )Nc S s g | ] }|j �qS r# )�__dict__)r6 r� r# r# r$ r� d s z)gather_all_validators.<locals>.<listcomp>c S s* i | ]"\}}t |t�s t |t�r||�qS r# )�hasattrr= rM )r6 r� r_ r# r# r$ r` e s � z)gather_all_validators.<locals>.<dictcomp>)r �__mro__rl )r� Zall_attributesr# r# r$ �gather_all_validatorsc s �r� )N)@rD � collectionsr � functoolsr r r � itertoolsr �typesr �typingr r r r r r r r r r r r Zpydantic.v1.errorsr Zpydantic.v1.typingr Zpydantic.v1.utilsr r r r rv r+ Zpydantic.v1.configr, Zpydantic.v1.fieldsr- Zpydantic.v1.typesr. r5 r r� rX re r/ �__annotations__r= rM r* rH rJ r; rW rq r| r~ r� r� r� r� r� r� r# r# r# r$ �<module> s� 8 &� � 7 � � � � � "$0' "!
