This should be the most portable version, so less specific may be better. * A list of positional arguments. * A dict of keyword arguments. Note that the positional or keyword arguments must contain values of the following types (including inner values of collection types): * None, bool, str, int, float, complex, set, frozenset, list, tuple, dict * UUID * datetime.datetime (naive), datetime.date * top-level classes, top-level functions - will be referenced by their full import path * Storage instances - these have their own deconstruct() method This is because the values here must be serialized into a text format (possibly new Python code, possibly JSON) and these are the only types with encoding handlers defined. There's no need to return the exact way the field was instantiated this time, just ensure that the resulting field is the same - prefer keyword arguments over positional ones, and omit parameters with their default values.

It is intended that AutoFieldMixin become public API when it is possible to create a non-integer automatically-generated field using column defaults stored in the database. In many areas Django also relies on using isinstance() to check for an automatically-generated field as a subclass of AutoField. A new flag needs to be implemented on Field to be used instead. When these issues have been addressed, this metaclass could be used to deprecate inheritance from AutoField and use of isinstance() with AutoField for detecting automatically-generated fields. c C s t tfS rH )r# r; ra rE rE rF � _subclasses� s zAutoFieldMeta._subclassesc s t || j�pt� �|�S rH )ro r� r� �__instancecheck__r� r� rE rF r� � s �z AutoFieldMeta.__instancecheck__c s t || j�pt� �|�S rH )r� r� r� �__subclasscheck__)rb �subclassr� rE rF r� � s �z AutoFieldMeta.__subclasscheck__) rB rC rD rE rF r� r� r� rI rE rE r� rF r� � s r� c @ s e Zd Zdd� Zdd� ZdS )r! c C s dS )Nr! rE ra rE rE rF r � s zAutoField.get_internal_typec C s t � j|d�S �Nr� )r4 r r rE rE rF r � s zAutoField.rel_db_typeN�rB rC rD r r rE rE rE rF r! � s r! )� metaclassc @ s e Zd Zdd� Zdd� ZdS )r# c C s dS )Nr# rE ra rE rE rF r � s z BigAutoField.get_internal_typec C s t � j|d�S r� )r$ r r rE rE rF r � s zBigAutoField.rel_db_typeNr� rE rE rE rF r# � s r# c @ s e Zd Zdd� Zdd� ZdS )r; c C s dS )Nr; rE ra rE rE rF r � s z SmallAutoField.get_internal_typec C s t � j|d�S r� )r< r r rE rE rF r � s zSmallAutoField.rel_db_typeNr� rE rE rE rF r; � s r; )e�collections.abcrp r� rk r� r0 r� r� �base64r r � functoolsr r �djangor Z django.appsr Z django.confr Z django.corer r r Z django.dbr r r Zdjango.db.models.constantsr Z django.db.models.query_utilsr r Z django.utilsr Zdjango.utils.datastructuresr Zdjango.utils.dateparser r r r Zdjango.utils.durationr r Zdjango.utils.functionalr r Zdjango.utils.ipv6r r Zdjango.utils.itercompatr Zdjango.utils.textr Zdjango.utils.translationr r` �__all__r. r5 r" rN rQ rR r/ r& r' r( rm ro rp r) r* r+ r, r- r0 r1 r4 r$ r< r3 r2 r6 r� r7 r8 r9 r: r= r> r? r% r@ r� r r� r! r# r; rE rE rE rF �<module> s� $ Y.rI AL*d ] %Hv@75
