上一篇我們學習如何配置Django開發(fā)環(huán)境，這一篇文章我們繼續(xù)來學習Django的內(nèi)容猿挚！
我們已經(jīng)創(chuàng)建了一個項目咐旧，大家還記得創(chuàng)建項目的命令嗎？django-admin startproject + 項目名绩蜻，我們接著來創(chuàng)建我們應(yīng)用铣墨，命令為：python manage.py startapp + 應(yīng)用名。查看一下應(yīng)用的目錄：
~/Desktop/projects/test1$ tree booktest/
booktest/
├── admin.py
├── __init__.py
├── migrations
│ └── __init__.py
├── models.py
├── tests.py
└── views.py
1 directory, 6 files
接起來我們需要在booktest下的models.py文件中編寫我應(yīng)用模板：
from django.db import models
# Create your models here.
class bookInfo(models.Model):
btitle = models.CharField(max_length=20)
bpub_data = models.DateField()
class hreoInfo(models.Model):
hname = models.CharField(max_length=10)
hgender = models.BooleanField()
hcontent = models.CharField(max_length=1000)
hbook = models.ForeignKey(bookInfo)
創(chuàng)建完模板我們在命令行運行一下办绝，看看效果：
~/Desktop/projects/test1$ python manage.py runserver 8080
Performing system checks...
System check identified no issues (0 silenced).
You have unapplied migrations; your app may not work properly until they are applied.
Run 'python manage.py migrate' to apply them.

生成數(shù)據(jù)表：
第一步需要在settings.py文件中注冊應(yīng)用伊约，
注冊應(yīng)用
第二步就是用命令行生成遷移文件：
~/Desktop/projects/test1$ python manage.py makemigrations
Migrations for 'booktest':
0001_initial.py:
- Create model bookInfo
- Create model hreoInfo
第三步就是執(zhí)行遷移文件：
~/Desktop/projects/test1$ python manage.py migrate

總結(jié)：本篇文章主要是講了，創(chuàng)建項目應(yīng)用孕蝉，編寫我們應(yīng)用模板屡律，如何生成數(shù)據(jù)表（注冊應(yīng)用，生成遷移文件降淮，執(zhí)行遷移文件）的學習操作超埋，希望對大家有幫助，Django學習是一個持續(xù)過程骤肛，我會記錄我的學習內(nèi)容教程纳本，歡迎大家一起學習。
