Bonsoir,

J'ai enfin réussi à configurer Python pour utiliser MySQL mais j'avoue ne pas bien saisir le fonctionnement des migrations. Dans tous les cas, je fais des essais mais suis bloqué. Et surtout je n'arrive pas à revenir en arrière même si j'ai remis ma class à son état initial.

Mon souci est le suivant :

python manage.py migrate Operations to perform: Apply all migrations: sessions, auth, country, contenttypes, admin, author Running migrations: Applying author.0002auto_20141112_1958...Traceback (most recent call last): File "manage.py", line 10, in <module> execute_from_command_line(sys.argv) File ".../lib/python3.4/site-packages/django/core/management/</module>init.py", line 385, in execute_from_command_line utility.execute() File ".../lib/python3.4/site-packages/django/core/management/init.py", line 377, in execute self.fetch_command(subcommand).run_from_argv(self.argv) File ".../lib/python3.4/site-packages/django/core/management/base.py", line 288, in run_from_argv self.execute(*args, *options.dict) File ".../lib/python3.4/site-packages/django/core/management/base.py", line 338, in execute output = self.handle(args, **options) File ".../lib/python3.4/site-packages/django/core/management/commands/migrate.py", line 160, in handle executor.migrate(targets, plan, fake=options.get("fake", False)) File ".../lib/python3.4/site-packages/django/db/migrations/executor.py", line 63, in migrate self.apply_migration(migration, fake=fake) File ".../lib/python3.4/site-packages/django/db/migrations/executor.py", line 97, in apply_migration migration.apply(project_state, schema_editor) File ".../lib/python3.4/site-packages/django/db/migrations/migration.py", line 107, in apply operation.database_forwards(self.app_label, schema_editor, project_state, new_state) File ".../lib/python3.4/site-packages/django/db/migrations/operations/fields.py", line 37, in database_forwards field, File ".../lib/python3.4/site-packages/django/db/backends/mysql/schema.py", line 42, in add_field super(DatabaseSchemaEditor, self).add_field(model, field) File ".../lib/python3.4/site-packages/django/db/backends/schema.py", line 376, in add_field definition, params = self.column_sql(model, field, include_default=True) File ".../lib/python3.4/site-packages/django/db/backends/schema.py", line 121, in column_sql default_value = self.effective_default(field) File ".../lib/python3.4/site-packages/django/db/backends/schema.py", line 184, in effective_default default = field.get_db_prep_save(default, self.connection) File ".../lib/python3.4/site-packages/django/db/models/fields/init.py", line 627, in get_db_prep_save prepared=False) File ".../lib/python3.4/site-packages/django/db/models/fields/init.py", line 1176, in get_db_prep_value value = self.get_prep_value(value) File ".../lib/python3.4/site-packages/django/db/models/fields/init.py", line 1171, in get_prep_value return self.topython(value) File ".../lib/python3.4/site-packages/django/db/models/fields/init.py", line 1128, in to_python parsed = parse_date(value) File ".../lib/python3.4/site-packages/django/utils/dateparse.py", line 37, in parse_date match = date_re.match(value) TypeError: expected string or buffer

Pouvez-vous m'aider ?

Merci d'avance.

J'ai trouvé une solution, j'ai supprimé tous les fichiers du dossier migrations de l'appli author et c'est reparti comme en 40.
