First we check the get_ordering() method in model admin, then we check the object's default ordering. Then, any manually-specified ordering from the query string overrides anything. Finally, a deterministic order is guaranteed by ensuring the primary key is used as the last ordering field. .-rJNr?z-pk)r7rQr+ get_orderingro ORDER_VARsplit rpartitionr#r,rvr^rS IndexErrorr1extendr;order_byr r?rqset) rArBr<r7rnZ order_paramsrnonepfxidxrtZ order_fieldZpk_namerCrCrDrys,      zChangeList.get_orderingc Cs|j}t}t|jkrxx|D]T}|jdr>|dd}d}nd}x.t|jD] \}}|j||krN|||<PqNWqWnbx`|jtjdD]L}|j d\}} } y t | } Wnt k rwYnX| dkrdnd|| <qW|S)zV Returns an OrderedDict of ordering field column numbers and asc/desc rxrJNdescZascrw) rorrzr7r^ enumerater#rvr{r|r,r1) rArnZordering_fieldsr\Z order_typeindexrurrrrrCrCrDget_ordering_field_columnss(      z%ChangeList.get_ordering_field_columnsc Cs|j|\|_|_}}|j}x&|jD]}|j||}|dk r$|}q$Wy|jf|}WnBttfk rnYn*tk r}zt |WYdd}~XnX|j j s|j |}|j ||}|j|}|jj|||j \}} || Br|jS|SdS)N)r]rZZ has_filtersr"r<filterrr Exceptionrr;select_relatedapply_select_relatedryrr+Zget_search_resultsZdistinct) rArBZremaining_lookup_paramsZfilters_use_distinctqsZ filter_specZnew_qsrrnZsearch_use_distinctrCrCrDr!5s(     zChangeList.get_querysetcCsB|jdkr|jS|jdkr,|jr,|jS|jr>|j|jS|S)NTF)r(r!has_related_field_in_list_display)rArrCrCrDrbs   zChangeList.apply_select_relatedc CsLxF|jD]<}y|jj|}Wntk r0YqXt|jtjrdSqWdS)NTF)r#r rpr rOZ remote_fieldrZ ManyToOneRel)rArtr\rCrCrDrns z,ChangeList.has_related_field_in_list_displaycCs6t||j}td|jj|jjft|f|jjj dS)Nzadmin:%s_%s_change)argsZ current_app) rsr@rrZ app_labelZ model_namer r+Z admin_siterq)rAresultr?rCrCrDurl_for_resultys    zChangeList.url_for_result)N)NN)__name__ __module__ __qualname__rErIr]rer=rorvryrr!rrrrCrCrCrDr%s1 2 !,!-  r),rV collectionsrZdjango.contrib.adminrZdjango.contrib.admin.exceptionsrrZdjango.contrib.admin.optionsrrrZdjango.contrib.admin.utilsr r r r Zdjango.core.exceptionsr rrZdjango.core.paginatorrZ django.dbrZ django.urlsrZ django.utilsrZdjango.utils.encodingrZdjango.utils.httprZdjango.utils.translationrr2rzZORDER_TYPE_VARr/r:r8rGobjectrrCrCrCrDs*
