预期验证错误，但出现 Keyerror

如何解决预期验证错误，但出现 Keyerror

我正在编写登录表单，在该表单下需要重新输入密码以进行验证。 当我输入正确的信息时，它正在工作，而当我输入空白表单键错误时，django 返回键错误。 有了正确的信息，它的工作就不会明白出了什么问题。

代码如下

library(tidyverse)
set.seed(1234)
n <- 20
tibble(partyname = sample(c("blue","red","green"),size = n,replace = T),x = rnorm(n)) %>% 
  group_by(partyname) %>% 
  mutate(n = n()) %>% 
  filter(n > 4)
#> # A tibble: 16 x 3
#> # Groups:   partyname [2]
#>    partyname        x     n
#>    <chr>        <dbl> <int>
#>  1 red        0.0183     11
#>  2 red        0.705      11
#>  3 green      0.868       5
#>  4 red        0.00501    11
#>  5 red       -0.0376     11
#>  6 green      0.724       5
#>  7 red       -0.497      11
#>  8 red        0.0114     11
#>  9 red        0.00986    11
#> 10 green      0.678       5
#> 11 red        1.03       11
#> 12 red       -1.73       11
#> 13 red       -2.20       11
#> 14 red        0.543      11
#> 15 green      0.163       5
#> 16 green      1.24        5

forms.py
class Login(forms.Form):
    name = forms.CharField()
    email = forms.EmailField()
    passwrd = forms.CharField(label='Password',widget=forms.PasswordInput)

        valname = self.cleaned_data['name']
        if valpwd != valrpwd:
            raise forms.ValidationError('Password does not match')
        if len(valname) < 4:
            raise forms.ValidationError('Enter More than 4 words')
        elif len(valname) > 20:
            raise forms.ValidationError('Enter less than 20 words')
        elif valname.isdigit():
            raise forms.ValidationError('No Number Allowed in Name')

登录.html

def signup(request):
    if request.method == 'POST':
        log = Login(request.POST)
        if log.is_valid():
            print('Form Validated')
            name = log.cleaned_data['name']
            email = log.cleaned_data['email']
            passwrd = log.cleaned_data['passwrd']
            rpasswrd = log.cleaned_data['rpasswrd']
            print('Name :',name)
            print('Email:',email)
            print('Password:',passwrd)
            print('Re-Password:',rpasswrd)
            return HttpResponseRedirect('/rk03/success/')

    else:
        log = Login()
        print('This is a GET request')
    return render(request,'rk03/login.html',{'form': log})
