一如既往、注册相关的知识点

1、Form组件

咱一般写Form的时都是拿它们形容于views视图里面,那么他与我们的视图函数也非影响,我们可以吧它仅仅另将出去,在动用下面建一个forms.py的文件来存放

2、局部钩子函数

 def clean_username(self):
        username = self.cleaned_data.get("username")
        valid = models.UserInfo.objects.filter(username = username).first()
        if valid:
            raise ValidationError("用户名已存在")
        return username

3、全局钩子函数

#自定义全局钩子:验证两次密码是否一致
 def clean(self):
   if self.cleaned_data.get("password") == self.cleaned_data.get("password_again"):
        return self.cleaned_data
   else:
        raise  ValidationError("两次密码不一致")

4、 jQuery的属性操作相关的

attr:
    一个参数是获取属性的值,两个参数是设置属性值
removeAttr(属性名):
    删除属性值
prop:
    适应于属性的返回值是布尔类型的(单选,反选,取消的例子)
removePorp:
    删除属性的值

5、循环的星星点点种办法:

$.each(数组/对象,function(i,v){})
$("div").each(function(i,v){})

6、css中之老三种植隐身:

1、display:none  隐藏所有内容
2、visibility:hidden  隐藏内容
3、overflow:hidden   隐藏溢出内容
三者都是用来隐藏的:
区别在于:
   visibility虽然隐藏了,但是被隐藏的内容依然占据这空间,这段隐藏了的内容却保留空间的位置会在网页中显示空白
   而display:隐藏了不占用空间
我们在注册的时候不用display:none,不然选择文件的那个功能就没有了,我们可以吧透明度

7、提交二进制数据用FormData

var formData=new FormData();
formData.append("username",$("#id_username").val()); 
formData.append("email",$("#id_email").val());
formData.append("tel",$("#id_tel").val());
formData.append("password",$("#id_password").val());
formData.append("password_again",$("#id_password_again").val());
formData.append("avatar_img",$("#avatar")[0].files[0]);

记忆要长

contentType:false
processData:false

8、可以据此脚的章程判断是啊要

if request.ajax():    #如果ajax请求
if request,method=="POST":   #如果是POST请求

9、上传文件来一个稳定的布参数media,和static相似 但又差

手续如下:


首先在settings中配置:

# ============media配置===============
MEDIA_URL="/media/"  #别名
MEDIA_ROOT=os.path.join(BASE_DIR,"app01","media","uploads")   #具体路径
  • 在url中配置

    url(r’^media/(?P.*)$’, serve, {‘document_root’: settings.MEDIA_ROOT}),

用处:

用处一:
-----      avatar = models.FileField(verbose_name='头像', upload_to='avatar', default="/avatar/default.png")
会把接收的文件放在media指代的路径与upload_to的拼接:BASE_DIR+blog+media+uploads+avatar/a.png
avatar字段在数据库中保存的是:avatar/a.png

用处二:

------     <img src="/media/avatar/a.png">

假使上传成会晤拿图纸自动保存于此处

10、头像图片预览

   //头像预览
        $(".avatar_file").change(function () {
            var ele_file = $(this)[0].files[0]; //当前选中的文件
            var reader = new FileReader();
            reader.readAsDataURL(ele_file); //对应找到打开的url
            reader.onload=function () {
{#                方式一#}
                $(".avatar_img").attr("src",this.result) ; //this.result是上面找到的url
{#                方式二#}
{#                 $(".avatar_img")[0].src=this.result; //设置图片属性#}
            }
        })

11、form自动生成的错误信息

当您定义了大局钩子的时刻,而且恰恰出现而的深全局钩子函数中之错(比如两不行密码输入不平等),这样您打印错误信息的时光

见面时有发生一个__all__目标,这个就是是您设置的全局钩子生成的。

图片 3

于是还要单独判断一下,现在全局钩子只来一个,你可以这样判断,但是,当全局钩子多之当儿即便得一个一个分离来判定

  if (i=="__all__"){
        $("#id_password_again").after($span)
   }

亚、具体贯彻登记操作
