使用django-csvimport的項目的遷移錯誤

Question

我在將Django 1.11應用程序投入生產時遇到了麻煩。

還有一個類似問題的問題，但我無法按需使用注釋中建議的答案： 應用程序csvimport的Django導入錯誤

如果我注釋掉settings.py中的代碼以刪除django-csvimport庫，例如：

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'rest_framework',
   # 'csvimport.app.CSVImportConf',
    'custom_app_name',

]

然后我的遷移工作正常，並且該應用程序運行（沒有csvimport應用程序）。 然后，如果我重新注釋csvimport APP行並運行遷移，則它們將失敗並顯示以下內容：

Operations to perform:
  Apply all migrations: admin, auth, contenttypes, csvimport, sessions, custom_app_name
Running migrations:
  Applying csvimport.0002_test_models...Traceback (most recent call last):

                                                             ^


The above exception was the direct cause of the following exception:

任何建議都將非常有幫助。
謝謝！

因此，我能夠根據讀取的堆棧跟蹤錯誤來解決此問題：

django.db.utils.ProgrammingError: syntax error at or near 
"csvtests_country"
LINE 1: ...CONSTRAINT "csvtests_item_country_id_5f8b06b9_fk_"csvtests_c...

問題在於，有一段生成的代碼在單引號內添加了雙引號，如下所示：

 options={
                'managed': True,
                'db_table': '"csvtests_country"',
            },

為了找到遷移，我去了虛擬環境的python安裝：

django_env/lib/python3.4/site-packages/csvimport/migrations/

並根據其他'db_table'：'sometable_name'調用均未使用雙引號的事實刪除雙引號。 我猜這是我將向csvimport github頁面報告的錯誤。 如果我找到更多信息，我將發布對此問題的任何更新。

希望這可以幫助處於類似情況的人。

謝謝！

更新：

我以前在csvimport github頁面的問題列表中沒有看到此消息。 它似乎是一個已知的錯誤： https : //github.com/edcrewe/django-csvimport/issues/77
