#|07.Django中的自定义认证方式和权限的设计与使用 #|Python实战之Django

一：自定义认证方式前提条件
【#|07.Django中的自定义认证方式和权限的设计与使用】1：建立简单的django工程
2：简单的login模块
3：基础的配置假设已经完成
4：User配置参考上一篇博客http://blog.csdn.net/gamer_gyt/article/details/50499653
以上如果哪点不明白，请查看前边章节诶的内容

login/views.py：

class LoginForm(forms.Form): username=forms.CharField(label="username:",max_length=100) email = forms.CharField(label = "email:" , max_length = 100) pwd = forms.CharField(label = "password:" , widget=forms.PasswordInput)

def login(request): if ('email' or 'pwd'or 'username') not in request.GET: lf = LoginForm() return render_to_response("login.html",{"lf":lf}) lf = LoginForm(request.GET) name = lf.data['username'] email = lf.data['email'] pwd = lf.data['pwd'] try: user = User.objects.get(email=email,username=name) except User.DoesNotExist: pass else: return HttpResponse("login in:" +user.username + user.email)

二：权限设计与应用新建一个blog模块，定义models.py:

class Blog(models.Model): blog_title = models.CharField(blank=False,verbose_name="标题",max_length=20,unique=True) #blank = False 表示该项必选 blog_time = models.DateTimeField(verbose_name="发表时间") blog_content = models.TextField(blank=False,verbose_name="内容") blog_seenum = models.IntegerField(verbose_name="浏览量",default=0) def __unicode__(self): return self.blog_title class Meta: db_table = "blog" permissions=( ("can_view","can see blogs"), ("can_add","can add blogs"), ("can_edit","can edit blogs"), ("can_delete","can delete blogs"), )

在admin.py中进行注册：

class BlogAdmin(admin.ModelAdmin): list_display = ('blog_title','blog_time','blog_seenum') list_filter = ('blog_title','blog_time','blog_seenum') search_fields = ('blog_title','blog_time','blog_seenum') fields = ('blog_title','blog_time','blog_content','blog_seenum') ordering = ('-blog_time',)

admin.site.register(Blog,BlogAdmin)

新建注册页面：regeister.html

Title - 锐客网 {{ lf.as_p }}

在logre的views模块中添加regeister函数

def regeister(request): if ('email' or 'pwd'or 'username') not in request.GET: lf = LoginForm() return render_to_response("regeister.html",{"lf":lf}) lf = LoginForm(request.GET) name = lf.data["username"] email = lf.data['email'] pwd = lf.data['pwd']user = User() user.username= name user.email = email user.pwd = pwd user.save()user.user_permissions = [Permission.objects.get(codename="can_view"),Permission.objects.get(codename='can_add')] user.save() return HttpResponseRedirect('/logre/login')

修改login函数为：

def login(request): if ('email' or 'pwd'or 'username') not in request.GET: lf = LoginForm() return render_to_response("login.html",{"lf":lf}) lf = LoginForm(request.GET) name = lf.data['username'] email = lf.data['email'] pwd = lf.data['pwd'] try: user = User.objects.get(email=email,username=name) except User.DoesNotExist: pass else: if user.check_password(pwd): if user.has_perm('blog.can_view'): return HttpResponse("you can see blogs") return HttpResponse("you can notsee blogs")

注册登录：
