如何在同一模板 (Django) 中通过表单向导表单使用多个表单

Question

我在同一个模板中使用多个表单，它们都可以工作，直到我添加我的表单向导，当它变成 FormWizard - 表单有效或其余表单有效但不是同时。

当我将带有 postid (?P\d+) -url 的 URL 置于 ContactWizard.as_view -url 之前视图中的表单 - 显示函数 one_labeling 但不显示 views.py class 中的表单 Wizard/ContactWizard.as_view ContactWizard(SessionWizardView)

url(r'^label$', LabelingIndex),
url(r'^label(?P<postID>\d+)$',one_labeling),# <----- here
url(r'^label',ContactWizard.as_view([Form1, Form2, Form3])),
url(r'^label(?P<one_labeling>\d+)/$', 'formwizard.views.one_labeling'),

反之亦然，当表单向导的 URL 位于 postID 之前 - url 用于视图函数中的表单 one_labeling 然后显示表单向导（和作品）但其他形式不是 displayed/evoked。

url(r'^label$', LabelingIndex),
url(r'^label',ContactWizard.as_view([Form1,Form2, Form3])),          
url(r'^label(?P<one_labeling>\d+)/$', 'formwizard.views.one_labeling'),
url(r'^label(?P<postID>\d+)$',one_labeling), #<----- here

我不确定如何为向导表单添加前缀，以便我可以将其用作 {{ form9.as_p }} 就像 {{ form3.as_p }} 而不是 {{ form1 } {{ wizard.management_form }} 或下面 done.html 中的 {{ form }}，以便它可以与模板 one_labeling_index.html 中的其他表单同时工作。

在模板中 done.html

{% extends 'base_one_labeling.html' %}

{% block content %}

   {% for form in form_data %}

       {{ form }}

   {% endfor %}

{% endblock %}

在views.py

class ContactWizard(SessionWizardView):

    template_name = "one_labeling_index.html"

    def done(self, form_list, **kwargs):


        form_data = process_form_data(form_list)

        return render_to_response("done.html",{"form_data":form_data})
def process_form_data(form_list):
    form_data = [form.cleaned_data for form in form_list]

    logr.debug(form_data[0]['subject'])
    logr.debug(form_data[1]['sender'])
    logr.debug(form_data[2]['message'])

    send_mail(form_data[0]['subject'],form_data[1]['sender'],
              form_data[2]['message'], 'xxxx@gmail.com',
              fail_silently=False)

    return form_data

in views.py,LabelingIndex,函数调用模板labeling_index.html

def LabelingIndex(request):
    #labelings, objects in class Labeling() in models.py
    labelings = Labeling.objects.all()

    c ={"labelings":labelings}
    c.update(csrf(request))
    return render(request,"labeling_index.html", c)

在views.py、one_labeling、视图函数one_labeling

def one_labeling(request,postID):
       #one_labeling, object in class Labeling  
      one_labeling= Labeling.objects.get(id=postID)
      template = one_labeling_index.html


      if request.method == "POST":
          # forms used in one_labeling_index.html

          form = SentenceForm(request.POST, prefix="sentence")
          form2 = OpenFileForm(request.POST, prefix="file")

          form3 = LabelingForm(request.POST,prefix="form3")
          form9 =LabelingForm2(request.POST,prefix="labeling") 
          if form.is_valid() and 'button1' in request.POST:
                   # do ....
          if form3.is_valid() and 'button2' in request.POST:
                   post_one_labeling(request.POST, one_labeling)

          else:
              form = SentenceForm()
              form2 = OpenFileForm()
              form3 = LabelingForm()

              form9 = LabelingRRGForm2()
          c = {"one_labeling":one_labeling,"form3":form3,"form":form,"form9":form9...... }

          c.update(csrf(request))


         return render(request,template,c,context_instance=RequestContext(request))

在模板中 Labeling_index.html

{% for one_labeling in labelings %}


  # Link to new id (postid) - page; template one_labeling.html 
  &nbsp;&nbsp Subject: <a href="/label{{ one_labeling.id }}">{{ one_labeling.title }}<a/><br/>



{% endfor %}

在模板中 one_labeling_index.html

# extending base_one_labeling.html
{% extends "base_one_labeling.html" %}
{% block content %}

# form3
<form3 action="" method="post" enctype="multipart/form-data">{% csrf_token %}

    {{ form3.as_p }}

</form3>

# Form Wizard 
  <p>Label {{ wizard.steps.step1 }} out of {{ wizard.steps.count }} ({{ wizard.steps.step1 }}/{{ wizard.steps.count }})</p>
  {% for field in form %}
    {{field.error}}
  {% endfor %}

  <form action="" method="post" enctype="multipart/form-data">{% csrf_token %}



  <table>
  {{ wizard.management_form }}
  {% if wizard.form.forms %}
      {{ wizard.form.management_form }}
      {% for form1 in wizard.form.forms %}
          {{ form1 }}
      {% endfor %}
  {% else %}
      {{ wizard.form }}
  {% endif %}
  </table>
  {% if wizard.steps.prev %}


  {% endif %}

Answer 1

行

url(r'^label',ContactWizard.as_view([Form1, Form2, Form3])),

匹配任何以 "label" 开头的 url，所以你放在后面的任何其他 url 都不会匹配。
此外，除了尾随的“/”，以下行：

url(r'^label(?P<one_labeling>\d+)/$', 'formwizard.views.one_labeling'),
url(r'^label(?P<postID>\d+)$',one_labeling), #<----- here

匹配相同的东西。
所以你必须仔细订购你的 urls，并以某种方式区分它们以避免任何歧义。
