ne peut pas importer sans id

Question

Logiciel:
Python3.6.2
Django1.11
django-import-export == 0.5.1
OSX10.12.6

INSTALLED_APPS:

THIRD_PARTY_APPS = [ 
    ..., 
    'reversion',  # django-reversion 
    'import_export', # django-import-export 
] 

Exigences:
1. Le modèle a reversion
2. Modèle peut être en mesure de faire import
3. Chaque rôle a importé Uploader comme created_user et updated_user (Cependant, juste pour l'instant je laisse lire à partir du fichier Excel et ici il est le problème)

tentatives:
1. Depuis deux des exigences frappera dur avec stricte classe meta. Ensuite, je demande reichert solution https://github.com/etianen/django-reversion/issues/323
2.

Answer 1

La solution est que je dois exposer id champ au fichier :(

ZIPCODE_BASIC_FIELDS = [ 
    'id', # Add 
    'zipcode', 
    'region', 
    'prefecture', 
    'city', 
    'town', 
    'building', 
] 

class ZIPCodeAddressResource(resources.ModelResource): 
    zipcode = fields.Field(widget=widgets.CharWidget()) 
    created_user = fields.Field(column_name='created_user', attribute='created_user', widget=widgets.ForeignKeyWidget(User, 'username')) 
    updated_user = fields.Field(column_name='updated_user', attribute='updated_user', widget=widgets.ForeignKeyWidget(User, 'username')) 

    class Meta: 
     model = ZIPCodeAddressImportExport 
     # exclude = ['id', ] # Need to remove this line 
     fields = IMPORT_COLUMNS 
     skip_unchanged = True 
     report_skipped = True 
     import_id_fields = ['id', ] # Let it had 'id' 
     export_order = IMPORT_COLUMNS
