Question

我在django项目'cc'中创建了一个新应用'api'。

我有一个远程数据库'launchg'，我使用Legacies将它与Django集成，并使用python manage.py inspectdb > models.py生成models.py文件。

接下来将生成的models.py文件替换为api app中的models.py文件。

每当我尝试将查询发送到此数据库时database error:no such table 对于例如： - WebQuery.objects.all()，它会引发错误，说明database error: no such table : web_query

这是我的models.py文件

    # This is an auto-generated Django model module.
    # You'll have to do the following manually to clean this up:
    #     * Rearrange models' order  
    #     * Make sure each model has one field with primary_key=True
    # Feel free to rename the models, but don't rename db_table values or field names.
    #
    # Also note: You'll have to insert the output of 'django-admin.py sqlcustom [appname]'
    # into your database.

此外，当我输入命令manage.py sql api时，它会显示所有表格。这是什么???

请帮助!!!

Answer 1

主要区别在于，manage.py sql myapphere触发将显示用于为数据库创建模式的查询，而myapp.objects.all()的输出将仅返回该数据库中条目的列表。

例如，如果您有文章列表，则manage.py sql命令将显示myapp 属性，而myapp.objects.all（）将显示myapp的实例< / em>在数据库中。

要进一步推断您的问题，请尝试打开您的数据库客户端，并确保列名称与模型中描述的列名称相匹配。如果它们不匹配，您可能需要删除表并重新同步数据库（我肯定有这个问题）。

数据库错误没有这样的表django
