Django迁移错误

Question

将Psycopg2 == 2.7.4导入服务器后，我将无法再正常运行服务器。 添加新字段之后，每当我尝试在makemigrations之后进行迁移（python manage.py migration）时，这就是现在在终端中发生的事情：

  Apply all migrations: admin, auth, buddysapp, contenttypes, oauth2_provider, sessions, social_django Running migrations: Applying buddysapp.0038_auto_20180321_0025...Traceback (most recent call last): File "manage.py", line 22, in <module> execute_from_command_line(sys.argv) File "/Users/hsi/Desktop/myvirtualenv/buddys/lib/python3.6/site-packages/django/core/management/__init__.py", line 367, in execute_from_command_line utility.execute() File "/Users/hsi/Desktop/myvirtualenv/buddys/lib/python3.6/site-packages/django/core/management/__init__.py", line 359, in execute self.fetch_command(subcommand).run_from_argv(self.argv) File "/Users/hsi/Desktop/myvirtualenv/buddys/lib/python3.6/site-packages/django/core/management/base.py", line 305, in run_from_argv self.execute(*args, **cmd_options) File "/Users/hsi/Desktop/myvirtualenv/buddys/lib/python3.6/site-packages/django/core/management/base.py", line 356, in execute output = self.handle(*args, **options) File "/Users/hsi/Desktop/myvirtualenv/buddys/lib/python3.6/site-packages/django/core/management/commands/migrate.py", line 202, in handle targets, plan, fake=fake, fake_initial=fake_initial File "/Users/hsi/Desktop/myvirtualenv/buddys/lib/python3.6/site-packages/django/db/migrations/executor.py", line 97, in migrate state = self._migrate_all_forwards(plan, full_plan, fake=fake, fake_initial=fake_initial) File "/Users/hsi/Desktop/myvirtualenv/buddys/lib/python3.6/site-packages/django/db/migrations/executor.py", line 132, in _migrate_all_forwards state = self.apply_migration(state, migration, fake=fake, fake_initial=fake_initial) File "/Users/hsi/Desktop/myvirtualenv/buddys/lib/python3.6/site-packages/django/db/migrations/executor.py", line 237, in apply_migration state = migration.apply(state, schema_editor) File "/Users/hsi/Desktop/myvirtualenv/buddys/lib/python3.6/site-packages/django/db/migrations/migration.py", line 129, in apply operation.database_forwards(self.app_label, schema_editor, old_state, project_state) File "/Users/hsi/Desktop/myvirtualenv/buddys/lib/python3.6/site-packages/django/db/migrations/operations/fields.py", line 84, in database_forwards field, File "/Users/hsi/Desktop/myvirtualenv/buddys/lib/python3.6/site-packages/django/db/backends/sqlite3/schema.py", line 231, in add_field self._remake_table(model, create_fields=[field]) File "/Users/hsi/Desktop/myvirtualenv/buddys/lib/python3.6/site-packages/django/db/backends/sqlite3/schema.py", line 113, in _remake_table self.effective_default(field) File "/Users/hsi/Desktop/myvirtualenv/buddys/lib/python3.6/site-packages/django/db/backends/sqlite3/schema.py", line 68, in quote_value raise ValueError("Cannot quote parameter value %r of type %s" % (value, type(value))) ValueError: Cannot quote parameter value <psycopg2._json.Json object at 0x10ea5e748> of type <class 'psycopg2._json.Json'> 

有什么想法，请告诉我。

更新：迁移文件0038

 rom __future__ import unicode_literals import buddysapp.models import django.contrib.postgres.fields.jsonb from django.db import migrations, models class Migration(migrations.Migration): dependencies = [ ('buddysapp', '0037_auto_20180318_1816'), ] operations = [ migrations.AddField( model_name='dispensary', name='businessHours', field=django.contrib.postgres.fields.jsonb.JSONField(blank=True, default=buddysapp.models.business_hours_default, null=True), ), migrations.AlterField( model_name='order', name='status', field=models.IntegerField(choices=[(1, 'Your Order Is Being Picked Right Off The Plant!'), (2, 'Picked, Weighed, And Ready For Delivery.'), (3, 'The Best Bud Is Heading Straight To Your Door.'), (4, 'Delivered'), (0, 'Canceled/Refunded')]), ), ] 

Answer 1

你不能使用JSONField从django.contrib.postgres与SQLITE3数据库。

您需要设置PostgreSQL数据库并更新DATABASES设置，或者在模型中使用其他字段。
