在一個Django表單集在後返回，所有形式展示各個領域的變化，即使沒有具有

這是一個非基於模型的形式：在一個Django表單集在後返回，所有形式展示各個領域的變化，即使沒有具有

from django import forms 


class MeasureForm(forms.Form): 
    name = forms.CharField(max_length=15) 
    description = forms.CharField(max_length=100) 
    datatype = forms.CharField(max_length=20) 
    uom = forms.Char

從非基於模型的視圖填充的：

def define_measures(request): 
    measureformset = formset_factory(MeasureForm, extra=2) 
    if request.method == 'POST': # If the form has been submitted... 
     formset = measureformset(request.POST) # A form bound to the POST data 
     if formset.is_valid(): # All validation rules pass 
      for form in formset: 
       print form.changed_data 
      return HttpResponseRedirect('/viscas/measures') # Redirect after POST 
    else: 


     measures = cass.get_all_measures() 

     list_dict =[] 
     for measure in measures: 
      list_dict.append({'name': measure.name, 'description': measure.description, 'datatype': measure.datatype, 'uom': measure.uom}) 

     formset = measureformset(initial=list_dict) 

    return render(request, 'viscas/measure.html', { 
     'formset': formset, 
    })

正在模板渲染「手動」：

{% extends "base.html" %} 
{% block content %} 
    <body> 
    <div class="container"> 
     <form action="{% url 'viscas:define_measures' %}" method="post"> 
      {% csrf_token %} 
      <div> 
       <table class="table table-hover" name="poi" id="tagTable"> 
        <thead> 
        <tr> 
         <th>UOM</th> 
         <th>Description</th> 
         <th>Datatype</th> 
         <th>UOM</th> 
        </tr> 
        </thead> 
        {% for form in formset %} 
         <tr> 
          <td>{{ form.name }}</td> 
          <td>{{ form.description }}</td> 
          <td>{{ form.datatype }}</td> 
          <td>{{ form.uom }}</td> 
          {% if form.errors %} 
           <tr> 
            <td>{{ form.errors }}</td> 
           </tr>{% endif %} 
         </tr> 
        {% endfor %} 
       </table> 
       {{ formset.management_form }} 
      </div> 
      <p></p><input type="submit" value="Submit"/></p> 
     </form> 
    </div> 
    </body> 

{% endblock %}

該頁面顯示漂亮，把我是否張貼有沒有變化WHA即使在網頁上，每個表格都顯示所有字段已更改（除了兩個額外的空白）。

從這個代碼：

if request.method == 'POST': # If the form has been submitted... 
    formset = measureformset(request.POST) # A form bound to the POST data 
    if formset.is_valid(): # All validation rules pass 
     for form in formset: 
      print form.changed_data

我得到這樣的輸出：

['name', 'description', 'datatype', 'uom'] 
['name', 'description', 'datatype', 'uom'] 
['name', 'description', 'datatype', 'uom'] 
['name', 'description', 'datatype', 'uom'] 
['name', 'description', 'datatype', 'uom'] 
['name', 'description', 'datatype', 'uom'] 
['name', 'description', 'datatype', 'uom'] 
['name', 'description', 'datatype', 'uom'] 
['name', 'description', 'datatype', 'uom'] 
['name', 'description', 'datatype', 'uom'] 
[] 
[]
