我在index.html中写道

＆＃13;

    <div class="heading col-lg-6 col-md-12">                     
            <h2>New account registration</h2>

              </div>

    </div>

＆＃13;

我想在用户名和密码输入标签的模板中设置minlength和maxlength。如果我在html stye中写道，它是

＆＃13;

<form class="form-horizontal" action="regist_save/" method="POST">                     
              <div class="form-group-lg">                     
                <label for="id_username">username</label>
                      <input id="id_username" name="username" type="text" value="" minlength="5" maxlength="12" placeholder="username" class="form-control">               
              </div>                                          
              <div class="form-group-lg">                     
                <label for="id_email">email</label>
                                      {{ regist_form.email }}
              </div>   
              <div class="form-group-lg">                     
                <label for="id_password">password</label>                     
                 <input id="id_password1" name="password1" type="password1" value="" minlength="8" maxlength="12" placeholder="password1" class="form-control">  
              </div>                                          
              <div class="form-group-lg">
                <label for="id_password">password（conformation）</label>                     
                 <input id="id_password2" name="password2" type="password2" value="" minlength="8" maxlength="12" placeholder="password2" class="form-control">  
                 <p class="help-block">{{ regist_form.password2.help_text }}</p>                     
              </div>                                          
              <div class="form-group-lg">
                <div class="col-xs-offset-2">
                <button type="submit" class="btn btn-primary btn-lg">SUBMIT</button>                     
                <input name="next" type="hidden"/>                     
                </div>
              </div>
              {% csrf_token %}                     
            </form>

＆＃13;

＆＃13; 在forms.py

中

class RegisterForm(UserCreationForm):
    class Meta:
        model = User
        fields = ('username', 'email','password1','password1',)
    def __init__(self, *args, **kwargs):
        super(RegisterForm, self).__init__(*args, **kwargs)
        self.fields['username'].widget.attrs['class'] = 'form-control'
        self.fields['email'].widget.attrs['class'] = 'form-control'
        self.fields['password1'].widget.attrs['class'] = 'form-control'
        self.fields['password2'].widget.attrs['class'] = 'form-control'

在views.py中

@require_POST
def regist_save(request):
    regist_form = RegisterForm(request.POST)
    if regist_form.is_valid():
        user = regist_form.save(commit=False)
        password = regist_form.cleaned_data.get('password')
        user.set_password(password)
        user.save()
        login(request, user)
        context = {
            'user': request.user,
        }
        return redirect('detail')

    context = {
        'regist_form': regist_form,
    }
    return render(request, 'registration/regist.html', context)

我想设置用户名minlength =＆＃34; 5＆＃34; ＆安培;最大长度=＆＃34; 12＆＃34;和密码minlength =＆＃34; 8＆＃34; ＆安培; maxlength =＆＃34; 12＆＃34;。我想把它写在模板中，虽然我在谷歌搜索但我找不到它。我想我可以通过模板来做但我会误解它吗？可以＆＃39; ti在模板中做到这一点？

Answer 1

您可以通过使用具有所需限制的这些属性来设置 maxlength 和 minlength ，并且验证将相应地运行
