如何在同一个模板(Django)中使用窗体向导窗体的多个窗体

Question

我在同一个模板中使用多个表单，它们都可以工作，直到我添加了我的表单向导，这时，FormWizard窗体或其馀的表单都可以工作，而不是同时工作。

当我将URL‘ContactWizard (?P\d+) -url放在ContactWizard.as_view -urls之前时，将显示视图函数one_labeling中的表单，而不是views.py类ContactWizard(SessionWizardView)中的表单向导/ContactWizard.as_ view。

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放在视图函数one_labeling中的表单的one_labeling-url之前时，FormWizard就会显示(并且工作)，但是其他的表单不会被显示/诱发。

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

我不确定如何在向导窗体的前缀上加上{ form9.as_p }}，以便在下面的done.html中以{ form3.as_p }}而不是{{ form1 }{ wizard.management_form }或{ form }使用它，以便它与模板one_labeling_index.html中的其他窗体并行工作。

模板done.html

{% extends 'base_one_labeling.html' %}

{% block content %}

   {% for form in form_data %}

       {{ form }}

   {% endfor %}

{% endblock %}

在views.py中

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

在views.py、LabelingIndex中，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、views函数one_labeling中

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))

模板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 %}

模板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 %}

线

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

匹配任何以"label“开头的url，因此您放置后的任何其他url都不会匹配。

此外，除后面的"/“字外，这些线：

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

匹配同样的东西。

因此，您必须仔细地排序您的urls，并以某种方式区分它们，以避免任何歧义。
