我在 django 项目“cc”中创建了一个新的应用程序“api”。

我有一个远程数据库“launchg”，我使用 Legacies 将它与 Django 集成并用于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应用程序中的 models.py 文件。

每当我尝试向此数据库发起查询时，database error:no such table 例如 :- WebQuery.objects.all()，它都会引发错误说明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，当我输入命令时manage.py sql api，它会显示所有表格。它是什么？？？

请帮忙！！！

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

例如，如果您有一个文章列表，manage.py sql 命令将显示 myapp属性，而 myapp.objects.all() 将显示数据库中 myapp 的实例。

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与您的模型中描述的列名匹配。如果它们不匹配，您可能需要删除表并重新同步您的数据库（我肯定有这个问题）。
