ProgrammingError：関係「何とか何とか」は、特定の移行を実行しようとして存在し、エラー

Question

を得ることはありません、私はエラーを取得しています：

$ python manage.py migrate swsite 0023_hitcounter.py

LINE 1: INSERT INTO "swsite_hitcounter" ("date", "template_location"... 

それが特異的であるように、これは私に混乱しています私は楽しみにしようとしています次の移行のようにswsite_hitcounterテーブルを構築しようとしている：

# -*- coding: utf-8 -*- 
# Generated by Django 1.9.5 on 2017-07-05 15:56 
from __future__ import unicode_literals 

from django.db import migrations, models 


class Migration(migrations.Migration): 

    dependencies = [ 
     ('swsite', '0022_auto_20170307_1343'), 
    ] 

    operations = [ 
     migrations.CreateModel(
      name='HitCounter', 
      fields=[ 
       ('id', models.AutoField(auto_created=True, primary_key=True, serialize=False, verbose_name='ID')), 
       ('date', models.DateTimeField(auto_now=True)), 
       ('template_location', models.TextField()), 
      ], 
     ), 
    ] 

は多分シンクのうち何ですか？これは私の制作ボックスでこのマイグレーションを実行しようとしているのですが、私の開発ボックスではうまくいきました。特定の移行を実行した原因は何ですか？ ：

python manage.py showmigrations

は私に同じエラーを与える：

Pythonはswsite 0023_hitcounter.py

もののランニングを移行manage.pyの？私はマイグレーションが同期していないと推測していますが、マイグレーションを表示できないため、このアップデートに含まれていないものを表示する方法はわかりません（ギラブ製作時）

Answer 1

トレースバックはあなたに表示されていますIndexViewにエラーが発生しています。ビューがロードされると、データベースにオブジェクトを作成しようとしています。ビューは次のようにロードするときに、データベースへのアクセス

class IndexView(TemplateView): 
    newhit = HitCounter.objects.create() # remove this line 
    ... 

は悪い考えですので、あなたはおそらく、行を削除する必要があります。本番環境では、テーブルを作成する移行を適用する前にデータベースにオブジェクトを作成しようとしているため、エラーが発生します。
