1146 "app_name.django_site missing"

Question

J'utilise Django 1.11 pour faire une application 'cnfs', et j'utilise la base de données MYSQL avec. Je suis constamment face à cette question où je reçois une erreur comme ça quand je tape le code suivant:

$python manage.py migrate 

System check identified some issues: WARNINGS: ?: (mysql.W002) MySQL Strict Mode is not set for database connection 'default' HINT: MySQL's Strict Mode fixes many data integrity problems in MySQL, such as data truncation upon insertion, by escalating warnings into errors. It is strongly recommended you activate it. See: https://docs.djangoproject.com/en/1.11/ref/databases/#mysql-sql-mode Operations to perform: Apply all migrations: admin, auth, cnfs, contenttypes, sites Running migrations: No migrations to apply.

J'ai littéralement passé des jours à ce sujet, je ne suis pas face à cette question quand j'utilisais la moteur de base de données django par défaut, sqlite3. Je l'ai essayé de faire ceci: $ python manage.py la migration des sites

Mon réglage SITE_ID est réglé sur 1 J'ai essayé d'enlever la chose « » django.contrib.sites du réglage INSTALLED_APPS, mais qui jette cette erreur :

Internal Server Error:/ Traceback (most recent call last): File "/home/ubuntu/.local/lib/python2.7/site-packages/django/core/handlers/exception.py", line 41, in inner response = get_response(request) File "/home/ubuntu/.local/lib/python2.7/site-packages/django/utils/deprecation.py", line 138, in call response = self.process_request(request) File "/home/ubuntu/.local/lib/python2.7/site-packages/subdomains/middleware.py", line 62, in process_request super(SubdomainURLRoutingMiddleware, self).process_request(request) File "/home/ubuntu/.local/lib/python2.7/site-packages/subdomains/middleware.py", line 38, in process_request (self.get_domain_for_request(request), request.get_host())) File "/home/ubuntu/.local/lib/python2.7/site-packages/subdomains/middleware.py", line 31, in get_domain_for_request return get_domain() File "/home/ubuntu/.local/lib/python2.7/site-packages/subdomains/utils.py", line 12, in current_site_domain from django.contrib.sites.models import Site File "/home/ubuntu/.local/lib/python2.7/site-packages/django/contrib/sites/models.py", line 84, in class Site(models.Model): File "/home/ubuntu/.local/lib/python2.7/site-packages/django/db/models/base.py", line 118, in new "INSTALLED_APPS." % (module, name) RuntimeError: Model class django.contrib.sites.models.Site doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS.

Toutes les suggestions seraient très appréciées.

Answer 1

uncomment la django.contrib.sites à partir d'applications installées

puis

python manage.py migrate sites 
python manage.py migrate 

si vous avez quelques tables dans la base de données, déposer les tables, puis exécutez ce
