Django FBV和CBV

1. FBV

# 1
def add_publisher(request):
    error_msg = ""
    # 如果是POST请求,我就取到用户填写的数据
    if request.method == "POST":
        new_name = request.POST.get("publisher_name", None)
        if new_name:
            # 通过ORM去数据库里新建一条记录
            models.Publisher.objects.create(name=new_name)
            # 引导用户访问出版社列表页,查看是否添加成功  --> 跳转
            return redirect("/publisher_list/")
        else:
            error_msg = "出版社名字不能为空!"
    # 用户第一次来,我给他返回一个用来填写的HTML页面
    return render(request, "add_publisher.html", {"error": error_msg})

# 2
url(r'^publisher_list/', views.publisher_list),

2. CBV

# 1
from django.views import View

class AddPublisher(View):
    def get(self, request):
        print(request.path_info)
        print(request.body)
        print("=" * 120)
        return render(request, "add_publisher.html")

    def post(self, request):
        print(request.body)
        print("=" * 120)
        new_name = request.POST.get("publisher_name", None)
        if new_name:
            # 通过ORM去数据库里新建一条记录
            models.Publisher.objects.create(name=new_name)
            # 引导用户访问出版社列表页,查看是否添加成功  --> 跳转
            return redirect("/publisher_list/")
        else:
            error_msg = "出版社名字不能为空!"
            return render(request, "add_publisher.html", {"error": error_msg})
