一、首先上代码、关于类视图：
class register(View):
#template_name = "templates/register.html"
def get(self,request):
return render_to_response("register.html")
def post(self,request):
username = request.POST.get("user")
password = request.POST.get("pswd")
emailstr = request.POST.get("email")
if None in [username,password,emailstr]:
return HttpResponseRedirect("/myapp1/register")
else:
password = gethash(password)
gender = request.POST.get("gender")
if gender not in [u"M",u"F"] and gender != None:
return HttpRequestRedirect("/myapp1/register")
userroll = int(request.POST.get("roll"))
if userroll not in [0,1] and userroll != None:
return HttpResponseRedirect("/myapp1/register")
try:
if userroll != None and gender != None:
LoginUser.objects.create(username=username,password=password,emailstr=emailstr,gender=gender,userroll=userroll)
elif userroll == None and gender != None:
LoginUser.objects.create(username=username,password=password,emailstr=emailstr,gender=gender)
else:
LoginUser.objects.create(username=username,password=password,emailstr=emailstr)
except Exception,ex:
print ex
return HttpResponseRedirect("/myapp1/register")
return HttpResponseRedirect("/myapp1/login")
要注意的是在对应urls.py的配置文件应该这么写：
from django.conf.urls import include, url
from django.contrib import admin
from myapp1 import views urlpatterns = [
# Examples:
# url(r'^$', 'mysite1.views.home', name='home'),
# url(r'^blog/', include('blog.urls')), url(r'^admin/', include(admin.site.urls)),
#url(r'^captcha/', include(captcha.urls)),
url(r'^myapp1/', include("myapp1.urls")),
#url(r'^register/',views.register.as_view())
]
from django.conf.urls import include, url
from myapp1 import views
#from myapp1.views import AccountRegister urlpatterns = [
# Examples:
# url(r'^$', 'mysite1.views.home', name='home'),
# url(r'^blog/', include('blog.urls')),
url(r'^login/', "myapp1.views.login"),
url(r'^mainpage/', "myapp1.views.main"),
url(r'^verifycode/', "myapp1.views.verify"),
url(r'^update/', "myapp1.views.update"),
url(r'^register/',views.register.as_view()),#注意没有引号没有引号没有引号
]
然后就可以啦，是不是很简单呢！
二、关于数据的更新和删除操作：
@logincheck.login_need
def update(request):
if request.method != 'POST':
return render_to_response("update.html")
else:
username = request.POST["user"]
password = request.POST["pswd"]
emailstr = request.POST["email"]
gender = request.POST["gender"]
if None in [username,password,emailstr]:
return render_to_response("update.html")
else:
password = gethash(password)
try:
print type(gender)
print repr(gender)
if gender in [u"M",u"F"]:
LoginUser.objects.filter(username=username,password=password,emailstr=emailstr).update(gender=gender)
else:
return render_to_response("update.html")
except Exception,ex:
return render_to_response("update.html")
return HttpResponseRedirect("/myapp1/mainpage?name=%s"%username)
核心代码部分：
LoginUser.objects.filter(username=username,password=password,emailstr=emailstr).update(gender=gender)
如果是删除就是这样啦：
LoginUser.objects.filter(username=username,password=password,emailstr=emailstr).delete()
三、关于一些约束条件：
#1、自增主键：
id = models.AutoField(primary_key=True)
#2、非空
blank=False
#3、唯一
unique=True
#4、默认值:
default= xxx
四、关于选项的数据库字段类型：
class LoginUser(models.Model):
gender_type = (
(u"F",u"female"),
(u"M",u"male")
)
userroll = models.IntegerField(default=1)
username = models.CharField(max_length=20)
password = models.CharField(max_length=64)
emailstr = models.CharField(max_length=50)
gender = models.CharField(max_length=1,choices=gender_type,default="M")
