Question

我正在学习Django并制作一个基本的应用程序，直到现在我已经编写了帐户处理部分，但是当我运行this.myform.setValue(mydata , 1)时，我得到的是控制台，我无法理解要查看哪个文件，

python manage.py migrate

到目前为止，我记得上次迁移后我已经更新了模板和url.py文件，这是我的urls.py。我仍然可以运行服务器，并且在前端看不到任何错误！

 Operations to perform:   Apply all migrations: accounts, admin, auth, contenttypes, sessions

Running migrations:   Applying accounts.0003_auto_20180910_1420...Traceback (most recent call last):  File "C:\Python\lib\site-packages\django\db\backends\utils.py", line 85, in _execute

    return Database.Cursor.execute(self, query, params) sqlite3.OperationalError: near ")": syntax error

The above exception was the direct cause of the following exception: Operations to perform:   Apply all migrations: accounts, admin, auth, contenttypes, sessions

    return executor(sql, params, many, context)

编辑1：

这是我的迁移文件-

urlpatterns = [
    path('admin/', admin.site.urls),
    path("signup/", accounts_views.signup, name='signup'),
    path('logout/', auth_views.LogoutView.as_view(), name='logout'),
    path('login/', auth_views.LoginView.as_view(template_name='login.html'), name='login'),
    path("", views.home, name='home'),
    path('reset/', auth_views.PasswordResetView.as_view(template_name='password_reset.html', email_template_name='password_reset_email.html', subject_template_name='password_reset_subject.txt'), name='password_reset'),
    path('reset/done/', auth_views.PasswordResetDoneView.as_view(template_name='password_reset_done.html'), name='password_reset_done'),
    path('reset/<int:pk>/', auth_views.PasswordResetConfirmView.as_view(template_name='password_reset_confirm.html'), name='password_reset_confirm'),
    path('reset/complete/', auth_views.PasswordResetCompleteView.as_view(template_name='password_resert_complete.html'), name='password_reset_complete'),
    path('settings/password/', auth_views.PasswordChangeView.as_view(template_name='password_change.html'),
    name='password_change'),
    path('settings/password/done/', auth_views.PasswordChangeDoneView.as_view(template_name='password_change_done.html'),
    name='password_change_done'),
    ]

第二个迁移文件-

# Generated by Django 2.0.5 on 2018-09-09 13:41

from django.conf import settings
import django.contrib.auth.models
from django.db import migrations, models
import django.db.models.deletion

class Migration(migrations.Migration):

    dependencies = [
        ('auth', '0009_alter_user_last_name_max_length'),
        ('accounts', '0001_initial'),
    ]

    operations = [
        migrations.CreateModel(
            name='User',
            fields=[
                ('user_ptr', models.OneToOneField(auto_created=True, on_delete=django.db.models.deletion.CASCADE, parent_link=True, primary_key=True, serialize=False, to=settings.AUTH_USER_MODEL)),
            ],
            options={
                'verbose_name': 'user',
                'verbose_name_plural': 'users',
                'abstract': False,
            },
            bases=('auth.user', models.Model),
            managers=[
                ('objects', django.contrib.auth.models.UserManager()),
            ],
        ),
        migrations.RemoveField(
            model_name='profile',
            name='user',
        ),
        migrations.DeleteModel(
            name='profile',
        ),
    ]

有人可以帮我吗？语法错误到底在哪里？

更新-我发现解决方案问题与sqllite3数据库有关。我搬到了postgresql，现在一切正常！

运行迁移时出错，返回Database.Cursor.execute（self，query，params）django.db.utils.OperationalError：附近的“）”：语法错误
