Django Admin no such table

Question

私はモデル言語を作成しました。私はmakemigrationsとmigrateの部分をしました。すべてうまくいった。私はdbを設定ファイルに登録しました。私は問題を見ない

from django.db import models 

class Oxn(models.Model): 
    objectId = models.CharField(max_length=100, unique=True) 
    name = models.CharField(max_length=100) 
    picture = models.CharField(max_length=200) 

class Language(models.Model): 
    objectId = models.CharField(max_length=100, unique=True) 
    code = models.CharField(max_length=10) 
    language = models.CharField(max_length=100) 

：私のモデルは、次のように定義されて

OperationalError at /admin/testdb/language/ 
no such table: testdb_language 
Request Method: GET 
Request URL: http://localhost:8000/admin/testdb/language/

：私はこれを取得、管理ページに言語テーブルをクリックし

。誰か助けてくれますか？

EDIT：移行から

Answer 1

0001_initial移行のginsdbアプリにはが含まれていますモデルなので、移行を実行したときに作成されているはずです。

まだ開発中で重要なデータがない場合、最も簡単なのはデータベースを削除し、新しいデータベースの移行を再実行することです。単にsqliteデータベースファイルを削除し、./manage.py migrateを再度実行してください。

データベースを保持する必要がある場合は、手動でモデルを作成することもできますが、これは扱いにくいものになります。

./manage.py sqlmigrate ginsdb 0001_initial
