异常值：没有这样的表：example_post

Question

我在尝试https://github.com/zhebrak/django-statsy

中的exemple文件时遇到了一些问题

OperationalError at /
no such table: example_post
Request Method: GET
Request URL:    http://localhost:8000/
Django Version: 1.11.5
Exception Type: OperationalError
Exception Value: no such table: example_post
Exception Location: /home/jeremie/.virtualenvs/statsy/local/lib/python2.7/site-packages/django/db/models/sql/compiler.py in execute_sql, line 894

这是我到目前为止所做的：

1. git clone https://github.com/zhebrak/django-statsy.git
2. mkvirtualenv statsy
3. cd django-statsy
4. workon statsy
5. pip install -r requirements.txt
6. python manage.py makemigrations
7. python manage.py migrate
8. python manage.py runserver

我只想进入example文件内部以查看结果类型并测试应用程序本身。为什么我有这个问题？如果我使用Django 1.10和python 2.7？

在项目中工作，您是否推荐此应用？

更新

┌─╼ [~/django-statsy]
└────╼ python2.7 manage.py makemigrations example
Migrations for 'example':
  example/migrations/0001_initial.py
    - Create model Post
┌─╼ [~/django-statsy]
└────╼ python2.7 manage.py migrate example
Operations to perform:
  Apply all migrations: example
Running migrations:
  Applying example.0001_initial... OK

以下是我运行localhost:8000：image

时的结果

我怎样才能测出给出的例子？

Answer 1

根据您在评论中的回复，看起来您还没有创建example_post数据库表。您需要将example添加到设置文件中的INSTALLED_APPS列表中，然后运行数据库迁移过程：

./manage.py makemigrations
./manage.py migrate

如果example应用程序不在INSTALLED_APPS中，则无法创建数据库迁移文件，因此无法创建表格。
