Question

我有django项目和一个应用程序。我没有模型，我想从现有的postgres数据库生成它们。我尝试了python manage.py inspectdb_refactor --database=default --app=igt和python manage.py inspectdb --database=default，但是django对于第一个事件仅使用__inti__.py生成路径，对于第二个事件（inspectdb）django生成空的models.py。怎么了？连接正常（因此DATABASE配置正常），应用已在设置中定义..什么问题？我的setting.py：

import os

# Build paths inside the project like this: os.path.join(BASE_DIR, ...)
import os, sys
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

UPD：现在，inspectdb（在迁移后）已在models.py中生成了一些Django类。

class AuthGroup(models.Model):
    name = models.CharField(unique=True, max_length=80)

    class Meta:
        managed = False
        db_table = 'auth_group'


class AuthGroupPermissions(models.Model):
    group = models.ForeignKey(AuthGroup, models.DO_NOTHING)
    permission = models.ForeignKey('AuthPermission', models.DO_NOTHING)

    class Meta:
        managed = False
        db_table = 'auth_group_permissions'
        unique_together = (('group', 'permission'),)


class AuthPermission(models.Model):
    name = models.CharField(max_length=255)
    content_type = models.ForeignKey('DjangoContentType', models.DO_NOTHING)
    codename = models.CharField(max_length=100)

    class Meta:
        managed = False
        db_table = 'auth_permission'
        unique_together = (('content_type', 'codename'),)

但未生成postgres数据库中的类

使用公共计划是个问题。我曾经在DATABASE的OPTIONS配置（settings.py）中更改必要方案的公共方案

DATABASE{
    'default':{
        //some configs
       'OPTIONS': {
              'options': '-c search_path=myownschema'
        }
    }
}

INSPECTDB和INSPECTDB_REFACTOR生成空模型
