django表单dateField验证失败

本文介绍了django表单dateField验证失败的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 我正在尝试在django中验证用户分析表单，我不能。似乎form.dateField（）有问题。它不验证（即is_valid（）返回false）

这是我的表单dateField条目： date_of_birth = forms.DateField （label = u'date of birth'，input_formats ='％d /％m /％Y'，required = False，widget = forms.DateInput（format ='％d /％m /％Y'））

我注意到 request.POST.get（'date_of_birth'，''）返回正确的日期（即我在html表单字段中键入的日期）。

我也注意到在这个函数中：

def clean_date_of_birth自我）： date = self.cleaned_data ['date_of_birth']

date对象总是没有。

我做错了什么？

编辑：

这是我要输入的内容： 29/07/1974 （1974年7月29日）

这是'提交'（各种请求）的输出

29/07/1974 个人资料表单是* NOT * valid [23 / Feb / 2012 12:16： 27]POST / profile / chris / HTTP / 1.1200 16289 29/7/1974 个人资料表单是* NOT * valid [23 / Feb / 2012 12 ：16：33]POST / profile / chris / HTTP / 1.1200 16289 1974-07-29 个人资料表单是* NOT * valid [23 / Feb / 2012 12:18:15]POST / profile / chris / HTTP / 1.1200 16289

这是我的模板。

< div class =input_area> < form id =profile_formmethod =postaction =/ profile / {{user.username}} /> {％csrf_token％} {{form.as_p}} < input type =submitid =submitvalue =saveclass =submitButton idlestyle =width：70px/> < / form> < / div>

这是我的views.py

def profile（request，username）： form = ProfileForm（request.POST） print request.POST.get（'date_of_birth'，'None'） try： user = User.objects.get（username = username）除了User.DoesNotExist： raise Http404（u'User not Found'）如果表单。 is_valid（）： print'个人资料表单有效' else： print'个人资料表单是* NOT * valid'

最后这是我的forms.py（目前不要使用clean_data函数）

class ProfileForm（forms.Form）： tz = [] timezones = Timezone.objects.all（）时区中的时区： val = str（timezone.hour）v = val.split（'：'） tuple =（timezone.id，'（'+ timezone.sign +''+ v [0] +' ：'+ v [1] +'）'+ timezone.name） tz.append（tup le） sex = [（'male'，'male'），（'female'，'female'），（'unknown'，'prefer not to say'）] real_name = forms.CharField（label = u'real name'，widget = forms.TextInput，required = False） date_of_birth = forms.DateField（label = u'date of birth'，input_formats ='％d /％ m /％Y'，required = False，widget = forms.DateInput（format ='％d /％m /％Y'）） pp_email = forms.EmailField（label = u'Paypal Email'，widget = form.TextInput，required = False） gender = forms.ChoiceField（label = u'sex'，choices = sex，widget = forms.Select（），required = False） timezone = forms.ChoiceField （label = u'time zone'，choices = tz，widget = forms.Select（）） address = forms.CharField（label = u'street address'，widget = forms.Textarea，required = False） postal = forms.CharField（label = u'postal code'，widget = forms.TextInput，required = False）

解决方案

输入格式列表或元组 docs.djangoproject/en/ dev / ref / forms / fields /＃django.forms.DateField.input_formats

I am trying to validate a User Profiling form in django and I can't. It seems that there is something wrong with forms.dateField(). It does not validate (ie. is_valid() return false)

this is my forms dateField entry: date_of_birth = forms.DateField(label=u'date of birth', input_formats='%d/%m/%Y', required=False, widget=forms.DateInput(format = '%d/%m/%Y'))

I noticed that request.POST.get('date_of_birth', '') returns the correct date (ie. the date I have typed in the html form field).

I also noticed that in this function:

def clean_date_of_birth(self): date = self.cleaned_data['date_of_birth']

date object is always None.

What am I doing wrong?

EDIT:

This is what I am trying to enter: 29/07/1974 (July 29th, 1974)

This is the output of 'submit' (various requests)

29/07/1974 profile form is *NOT* valid [23/Feb/2012 12:16:27] "POST /profile/chris/ HTTP/1.1" 200 16289 29/7/1974 profile form is *NOT* valid [23/Feb/2012 12:16:33] "POST /profile/chris/ HTTP/1.1" 200 16289 1974-07-29 profile form is *NOT* valid [23/Feb/2012 12:18:15] "POST /profile/chris/ HTTP/1.1" 200 16289

This is my template

<div class="input_area"> <form id="profile_form" method="post" action="/profile/{{ user.username }}/">{% csrf_token %} {{ form.as_p }} <input type="submit" id="submit" value="save" class="submitButton idle" style="width:70px" /> </form> </div>

this is my views.py

def profile(request, username): form = ProfileForm(request.POST) print request.POST.get('date_of_birth', 'None') try: user = User.objects.get(username=username) except User.DoesNotExist: raise Http404(u'User not Found') if form.is_valid(): print 'profile form is valid' else: print 'profile form is *NOT* valid'

and finally this is my forms.py (do not use clean_data functions at the moment)

class ProfileForm(forms.Form): tz = [] timezones = Timezone.objects.all() for timezone in timezones: val = str(timezone.hour) v = val.split(':') tuple = (timezone.id, '('+timezone.sign+''+v[0]+':'+v[1]+') '+timezone.name) tz.append(tuple) sex = [('male','male'),('female', 'female'),('unknown', 'prefer not to say')] real_name = forms.CharField(label=u'real name', widget=forms.TextInput, required=False) date_of_birth = forms.DateField(label=u'date of birth', input_formats='%d/%m/%Y', required=False, widget=forms.DateInput(format = '%d/%m/%Y')) pp_email = forms.EmailField(label=u'Paypal Email', widget=forms.TextInput, required=False) gender = forms.ChoiceField(label=u'sex', choices=sex, widget=forms.Select(), required=False) timezone = forms.ChoiceField(label=u'time zone', choices=tz, widget=forms.Select()) address = forms.CharField(label=u'street address', widget=forms.Textarea, required=False) postal = forms.CharField(label=u'postal code', widget=forms.TextInput, required=False)

解决方案

input formats in DateField must be list or tuple docs.djangoproject/en/dev/ref/forms/fields/#django.forms.DateField.input_formats
