Cela fonctionne pour
>>> python -m django version
2.0.7
Voici comment procéder :
>>> from django.apps import apps
>>> polls_tables = apps.get_app_config("polls")
>>> polls_tables.models
OrderedDict([('question', <class 'polls.models.Question'>), ('choice', <class 'polls.models.Choice'>), ('reporter', <class 'polls.models.Reporter'>), ('article', <class 'polls.models.Article'>), ('publication', <class 'polls.models.Publication'>), ('publicationarticle_publications', <class 'polls.models.PublicationArticle_publications'>), ('publicationarticle', <class 'polls.models.PublicationArticle'>), ('person', <class 'polls.models.Person'>), ('group', <class 'polls.models.Group'>), ('membership', <class 'polls.models.Membership'>), ('place', <class 'polls.models.Place'>), ('restaurant', <class 'polls.models.Restaurant'>), ('waiter', <class 'polls.models.Waiter'>), ('student', <class 'polls.models.Student'>), ('assembler', <class 'polls.models.Assembler'>), ('bike', <class 'polls.models.Bike'>), ('blog', <class 'polls.models.Blog'>), ('author', <class 'polls.models.Author'>), ('entry_authors', <class 'polls.models.Entry_authors'>), ('entry', <class 'polls.models.Entry'>), ('themeblog', <class 'polls.models.ThemeBlog'>), ('bookauthor', <class 'polls.models.BookAuthor'>), ('publisher', <class 'polls.models.Publisher'>), ('book_authors', <class 'polls.models.Book_authors'>), ('book', <class 'polls.models.Book'>), ('store_books', <class 'polls.models.Store_books'>), ('store', <class 'polls.models.Store'>), ('dummy', <class 'polls.models.Dummy'>)])
>>> polls_tables.models.keys()
odict_keys(['question', 'choice', 'reporter', 'article', 'publication', 'publicationarticle_publications', 'publicationarticle', 'person', 'group', 'membership', 'place', 'restaurant', 'waiter', 'student', 'assembler', 'bike', 'blog', 'author', 'entry_authors', 'entry', 'themeblog', 'bookauthor', 'publisher', 'book_authors', 'book', 'store_books', 'store', 'dummy'])
vous pouvez également obtenir les noms des champs d'un modèle particulier
>>> questionTable = polls_tables.get_model("question")
>>> questionTable._meta.get_fields()
(<ManyToOneRel: polls.choice>, <django.db.models.fields.AutoField: id>, <django.db.models.fields.CharField: question_text>, <django.db.models.fields.DateTimeField: pub_date>)
De plus, si vous le souhaitez, vous pouvez en obtenir le décompte en
>>> len(questionTable._meta.get_fields())
4
Pour obtenir toutes les valeurs de la base de données, vous pouvez procéder comme suit :
>>> list = [entry for entry in Entry.objects.values()]
>>> for dict in list:
... print()
... for key in dict:
... print(key," : ", dict[key])
