Question

请帮助解决问题。

我用密码更改的形式制作了一个页面。但是在第一次启动时（在用户将数据输入表单之前）提示“是必填字段”。

仅当用户错误地提交完整的表单时，我才需要显示这些提示。

urls.py:

urlpatterns = patterns('drummersaransk',
    url(r'^$', 'views.page'),
    url(r'^userprofile/password_page/', 'views.password_page'),     
    url(r'^userprofile/password_page_changed/', 'views.password_page_changed'),     
    url(r'^admin/', include(admin.site.urls)),
)

views.py:

@login_required 
def password_page(request):     
    if request.method == 'POST':                                
        form = ChangePasswordForm(request.POST, request=request)
        if form.is_valid():
            username = User.objects.get(username__exact=request.user.username)
            username.set_password(form.cleaned_data.get('password1'))
            username.save() 
            return HttpResponseRedirect('/userprofile/password_page_changed/')                      
    else:                       
        form = ChangePasswordForm(request.POST or None, request=request)

    t = loader.get_template('password_page.html')
    c = RequestContext(request, {
                                    'form': form,
    }, [custom_proc])   

    return HttpResponse(t.render(c))

password_page.html：

{% extends "page_base.html" %}

{% block title %}User profile - pass{% endblock %}

{% block content %}
    <h2>pass page</h2>

    {% for field in form %}
        {{ field.error }}
    {% endfor %}    

    <form action="/userprofile/password_page/" method="POST">{% csrf_token %}
        {{ form.as_p }}

        <input type="submit" value="send" />
    </form>

{％endblock％}

forms.py：

from django import forms
from django.contrib.auth.models import User
from django.contrib.auth.forms import UserCreationForm
from django.forms import ModelForm

from drummersaransk.models import UserProfile


class ChangePasswordForm(forms.Form):
    password_old = forms.CharField(max_length=30, widget=forms.PasswordInput())
    password1 = forms.CharField(widget=forms.PasswordInput())
    password2 = forms.CharField(widget=forms.PasswordInput())

    def __init__(self, post, request, *args, **kwargs):
        self.post = post
        self.request = request
        super(ChangePasswordForm, self).__init__(post, request, *args, **kwargs)        

    def clean_password_old(self):
        cleaned_data = self.cleaned_data
        password_old = cleaned_data.get("password_old") 
        if not self.request.user.check_password(password_old):
            raise forms.ValidationError("old Password is not correct")
        else:
            return password_old

    def clean(self):    
        cleaned_data = self.cleaned_data
        password1 = cleaned_data.get("password1")
        password2 = cleaned_data.get("password2")   

        if password1 != password2:      
            raise forms.ValidationError("Passwords must be same")
        else:                           
            return cleaned_data

如果不是POST，您不应该将位置参数中的任何内容传递给表单。

form = ChangePasswordForm(request=request)

修改

正如我所说，你在ChangePasswordForm的定义中做了一些奇怪的事情。您接受了post和request个参数 - 即使您根本没有真正使用post - 而且，更糟糕的是，您已经过了将它们放到超类的__init__方法上，即使它没有预料到它们。

这样做的方法是仅接受request，但要在kwargs中这样做。这样，您就不会更改功能签名，您可以选择是否将其传递给超类。

class ChangePasswordForm(forms.Form): def __init__(self, *args, **kwargs): self.request = kwargs.pop('request', None) super(ChangePasswordForm, self).__init__(*args, **kwargs)
