问题描述

u'ManagementForm数据丢失或已被篡改

>

那就是我的代码：
请指出我的错误并帮助我解决这个问题。

  @csrf_protect 
 @ transaction.commit_on_success 
 def signup（request）：
 form = NewUserCreationForm（）
 doc_form = NewDocRegisterForm（）
 
 SpecialityLicensesFormSet = modelformset_factory（SpecialityLicenses，extra = 1，exclude =（'user'））
 formset = SpecialityLicensesFormSet（queryset = SpecialityLicenses.objects.none（））
 
如果有请求。方法==POST：
 $ b $ form = NewUserCreationForm（request.POST或None）
 doc_form = NewDocRegisterForm（request.POST或None）
 formset = SpecialityLicensesFormSet（request.POST或无）
 
 
如果form.is_valid（）和doc_form.is_valid（）和formset.is_v alid（）：
 
 user = form.save（）
 
 doc = doc_form.save（commit = False）
 doc.user = user 
 doc.save（）
 
 
 $ b printsetset 
 fset = formset.save（commit = False）
 
 for fset： 
 n.user = user 
 n.save（）
 
 return HttpResponse（Uzytkownik utowrzony）
 
 return render_to_response（userena / signup_new。 html'，{'form'：form，
'doc_form'：doc_form，$ b $'spec_form'：formset，}，
 context_instance = RequestContex 
 
t（request） ）
  

模板代码：

 < form action =/ en / accounts / doc_register /method =post> {％csrf_token％} 
 {％for field in form％} 
 
 
 < DIV> 
 {％if field.errors％} 
 {{field.errors | striptags}} | 
 {％endif％} 
 
 {{field.label}} | {{field}} 
< / div> 
 
 
 {％endfor％} 
 
< hr> 
 
 
 {％for f in doc_form％} 
< div> 
 {％if f.errors％} 
 {{f.errors | striptags}} | 
 {％endif％} 
 
 {{f.label}}：{{f}} 
< / div> 
 {％endfor％} 
< hr> 
 
 {{spec_form.management_form}} 
 {{spec_form}} 
 
< hr> 
< input type =submitvalue =Submit/> 
< / form> 
 {％endblock％} 
  

解决方案

如果你做了 {{formset}} ，就不需要做 {{formset.management_form}} ，只要你做

$ $ p $ code $ {formset.management_form}}
{％for formset％}
{{请尝试删除







< {{spec_form.management_form}} 位。查看第三个示例

I am still fighting with formsets and I cant really understand why I am getting this error:

u'ManagementForm data is missing or has been tampered with

Thats my code: Please point out my mistakes and help me with resolving this issue.

@csrf_protect
@transaction.commit_on_success
def signup(request):
    form = NewUserCreationForm()
    doc_form = NewDocRegisterForm()

    SpecialityLicensesFormSet = modelformset_factory(SpecialityLicenses, extra=1, exclude = ('user'))
    formset = SpecialityLicensesFormSet(queryset=SpecialityLicenses.objects.none())

    if request.method == "POST":

        form = NewUserCreationForm(request.POST or None)
        doc_form = NewDocRegisterForm(request.POST or None)
        formset = SpecialityLicensesFormSet(request.POST or None)


        if form.is_valid() and doc_form.is_valid() and formset.is_valid():

            user = form.save()

            doc = doc_form.save(commit=False)
            doc.user = user
            doc.save()



            print formset
            fset = formset.save(commit=False)

            for n in fset:
                n.user = user
                n.save()

            return HttpResponse("Uzytkownik utowrzony")

    return render_to_response("userena/signup_new.html", {'form': form,
                                                          'doc_form': doc_form,
                                                          'spec_form': formset,}, 
                              context_instance=RequestContex

t(request)) 

Template code:

<form action="/en/accounts/doc_register/" method="post">{% csrf_token %}
    {% for field in form %}


    <div>
        {% if field.errors %}
            {{ field.errors|striptags }} |
        {% endif %}

        {{field.label}} | {{ field}}
    </div>


    {% endfor %}

    <hr>


    {% for f in doc_form %}
    <div>
    {% if f.errors %}
    {{f.errors|striptags}} | 
    {% endif %}

    {{f.label}} : {{ f }}
    </div>
    {% endfor %}
    <hr>

    {{ spec_form.management_form }}
    {{ spec_form }}

            <hr>
    <input type="submit" value="Submit"/>
</form>
{% endblock %}

解决方案

you don't need to do {{ formset.management_form }} if you do {{ formset }}, just if you do

{{ formset.management_form }}
{% for form in formset %}
  {{ form }}
{% endfor %}

try removing the {{ spec_form.management_form }} bit from your template. Look at the third example
