Django第四天：博客项目实战

如何导出所有库？

使用

pip freeze >requirements.txt
导出所有库
pip install -r requirements.txt
安装所需的库

　本地化设置-项目目录下的settings.py

设置language_code为zh-hans

设置time-zone为Asia/Shanghai

设置了2个模型类，一个为BlogType，博客分类，一个为博客模型

class BlogType(models.Model):
    type_name = models.CharField(max_length=15)

    def __str__(self):
        return self.type_name


class Blog(models.Model):
    title = models.CharField(max_length=50)
    blog_type = models.ForeignKey(BlogType, on_delete=models.DO_NOTHING)
    content = models.TextField()
    author = models.ForeignKey(User, on_delete=models.DO_NOTHING)
    created_time = models.DateTimeField(auto_now_add=True)
    last_updated_time = models.DateTimeField(auto_now_add=True)

    def __str__(self):
        return "<Blog:%s>" % self.title

　并在admin中应用

@admin.register(BlogType)
class BlogTypeAdmin(admin.ModelAdmin):
    list_display = ('id', 'type_name')


@admin.register(Blog)
class BlogAdmin(admin.ModelAdmin):
    list_display = ('title', 'blog_type', 'author', 'created_time', 'last_updated_time')
