django表单集无法验证，因为需要ID [英] django formset not validating because ID is required

问题描述

MY视图从模板接收到一个模型表单集，但未通过验证，声称需要ID。到目前为止，我对表单的使用从未提出过这个问题，而且我也从来不需要传递ID。

MY view receives a model formset from the template, but it doesn't pass validation, claiming that ID is required. Al my use of forms until now has never brought up this problem, and I've never had to pass ID's around.

这里是我的观点的简化版本：

Here is a simplified version of my view:

def BudgetView(request):

    import pdb
    pdb.set_trace()

    if request.user.is_authenticated:
        U=request.user

        #initalize formset factories
        ItemFormSet = modelformset_factory(Item, fields=(blabla), extra=0)
        CatFormset=modelformset_factory(BudgetCatagory, fields=(blabla), extra=0)

        #initalize Constants
        InitiateConstants(CatagoryItemsList)

        if request.method=='POST':
            FormsetItem=ItemFormSet(request.POST,initial=Item.objects.filter(budgetcatagory__user_id=U.id).values())
            FormsetCat=CatFormset(request.POST)
            if FormsetItem.is_valid():
-bla
-bla
-bla

            return redirect('/HighLevelInput')
        else:
            #populate
            I=Item.objects.filter(budgetcatagory__user_id=U.id)
            C=BudgetCatagory.objects.filter(user_id=U.id)

            #initiate initial catagories and items for new user
            if (not I.exists()) or (not C.exists()):
                Item.objects.filter(budgetcatagory__user_id=U.id).delete()
                BudgetCatagory.objects.filter(user_id=U.id).delete()
                InitiateNewUser(U)
                I=Item.objects.filter(budgetcatagory__user_id=U.id)
                C=BudgetCatagory.objects.filter(user_id=U.id)
            FormsetItem=ItemFormSet(queryset=I)
            FormsetCat=CatFormset(queryset=C)

        return render(request,'getdata/budgetmachine.html', {'FormsetItem':FormsetItem, 'FormsetCat':FormsetCat })
    else:
        return redirect('/login')

is_valid返回reaso为FALSE我上面已经提到过。
有什么想法吗？

is_valid returns FALSE for the reason I've mentioned above. any ideas?

根据要求，以下是is_valid检查返回的错误：

As requested, here are the errors returned from the is_valid check:

(Pdb) FormsetItem.errors
[{'id': ['This field is required.']}, {'id': ['This field is required.']}, {'id': ['This field is required.']}, {'id': ['This field is required.']}, {'name': ['This field is required.'], 'detail': ['This field is required.'], 'layout': ['This field is required.'], 'unit': ['This field is required.'], 'unit_description': ['This field is required.'], 'parent': ['This field is required.'], 'enName': ['This field is required.'], 'id': ['This field is required.']}, {'id': ['This field is required.']}, {'id': ['This field is required.']}, {'id': ['This field is required.']}, {'id': ['This field is required.']}, {'id': ['This field is required.']}, {'id': ['This field is required.']}, {'id': ['This field is required.']}, {'id': ['This field is required.']}, {'id': ['This field is required.']}, {'id': ['This field is required.']}, {'name': ['Ensure this value has at most 30 characters (it has 32).'], 'parent': ['Ensure this value has at most 30 characters (it has 32).'], 'id': ['This field is required.']}, {'id': ['This field is required.']}, {'id': ['This field is required.']}, {'id': ['This field is required.']}, {'id': ['This field is required.']}, {'id': ['This field is required.']}, {'id': ['This field is required.']}, {'id': ['This field is required.']}, {'id': ['This field is required.']}, {'id': ['This field is required.']}, {'id': ['This field is required.']}]

在这里是我的模板：

{% block body %}

<div class="container" style="width:80%">

  <form method="post">
    {% csrf_token %}
    {{ FormsetItem.management_form }}
    {{ FormsetCat.management_form }}

    <table>
      <tr>
        <th>פריט</th>
        <th>מחיר מתוקצב</th>
        <th>מיקום מחיר</th>
        <th>רמת פירוט</th>
        <th>רמת פירוט</th>
      </tr>

      <!--unpacks the item dictionary into formsets -->
      {% for CatForm in FormsetCat %}
        <tbody onmouseenter="ToggleDisable('{{ CatForm.enName.value}}')" onmouseleave="ToggleDisable('{{ CatForm.enName.value}}')">
          {% for ItemForm in FormsetItem %}
            {% if ItemForm.parent.value == CatForm.name.value %}
                {% if ItemForm.layout.value == 'normal' %}
                  {% include 'getdata/normalBudgetLayout.html' with form=ItemForm itemCount=forloop.counter0 catagoryCount=forloop.parentloop.counter0 %}
                {% elif ItemForm.layout.value == 'choice' %}
                  {% include 'getdata/choiceBudgetLayout.html' with form=ItemForm itemCount=forloop.counter0 catagoryCount=forloop.parentloop.counter0 %}
                {% endif %}
            {% endif %}
          {% endfor %}
        <tr class="txt_center Row_{{ CatForm.enName.value}}" style="line-height:4em; background:Silver;">
          <td>
            <a onclick="ToggleDisable('{{ CatForm.enName.value}}')">
              {{ CatForm.name.value }}
              <span style="float:left;">
                <i class="fa fa-caret-down {{ CatForm.enName.value}}" style="font-size:30px; padding:7px;"></i>
                <i class="fa fa-caret-up {{ CatForm.enName.value}}" style="font-size:30px; padding:7px;" hidden></i>
              </span>
            <!--/a-->
          </td>
          <td>{{ CatForm.catagory_cost }}</td>
          <td>TBD</td>
          <td>{{ CatForm.detail.value }}</td>
          <td></td>
        </tr>
        </tbody>
      {% endfor %}
    </table>
    <br />
    <br />
    <br />
    <button type="submit" >Submit</button>    <br />
    <br />

  </form>
</div>




{% endblock %}

推荐答案

ModelFormsets 需要 form.id 。它呈现为隐藏字段。您将需要同时使用两个表单集。

ModelFormsets require form.id. It is rendered as a hidden field. You will need to implement it with both formsets.

{% for form in formset %}
    {% for hidden in form.hidden_fields %}
        {{ hidden }}
    {% endfor %}
    <!-- form.visible fields go here -->
{% endfor %}
