crm项目之登录验证(密码使用密文),前端使用django的form组件
crm项目01 登录验证(密码使用md5密文)
项目要点
0.自定义form类
exclude[ ] 除去列表中的字段
1.验证使用django的form组件
其中,注意is_valid()判断前端传过来的值是否全部正确.如果正确是True,查看源码之后,其中进行的顺序是
is bound and errors 局部钩子, 全局钩子同时可以报出异常
获取组件的最后传过来的值使用.cleaned_data方法,cleaned_data是一个字典,使用get获取时要如图片写,防止值为空时获取不到报错,
定义全局钩子时,一定要记得返回全局的cleaned_data
2.要将form表单的样式渲染,要在自定义的form表单类定义初始化方法.
def __init__(self, *args, **kwargs): super().__init__(*args,**kwargs) # print(self.fields) for field in self.fields.values(): field.widget.attrs.update({'class':'form-control'})
self.fields的结果是一个有序字典,所以遍历它,获取它的value并更新字典
3.将form表单传给前端渲染字段,前端要这样写
<div class="form-group"> <label for="{{ form_obj.mobile.id_for_label }}" class="col-sm-2 control-label">{{ form_obj.mobile.label }}</label> <div class="col-sm-10"> {{ form_obj.mobile }}{{ form_obj.mobile.errors.0 }} </div> </div>
其中的from_obj来自视图函数中定义的obj,其中 form_obj = RegForm(request.POST)就是将post过来的数据传递给regform这个自己写的表单类
# 注册 def reg(request): # 判断请求方式 if request.method == 'POST': form_obj = RegForm(request.POST) # 对数据进行校验 if form_obj.is_valid(): # 数据正确 插入数据库 # print(form_obj.cleaned_data) # form_obj.cleaned_data.pop('re_password') # models.UserProfile.objects.create(**form_obj.cleaned_data) form_obj.save() return redirect(reverse('login')) else: form_obj = RegForm() return render(request, 'reg.html', {'form_obj': form_obj})
4.form表单的label默认传给前端页面时使用的是models里面创建时的字段,
会出现如下情况,有的字段标签是英文.修改这里有两种方法,一种是在自定义的Regform类中修改,一种是在models文件的字段中添加verbose_name='密码' 这样的参数
------1.在models.py的字段中修改
图中没有使用verbose_name的原因是 charfield的源码中 第一个位置参数就是verbose_name,最好还是写上比较好
-------2. 在Regform即自定义的form类中创建
5.前端页面不让浏览器弹出要在form表单标签中加入novalidate属性
为了防止这种效果发生,这样加入属性
