Question

我的视图从模板接收模型formset，但它没有通过验证，声称需要ID。到目前为止，我对形式的使用从未提出过这个问题，而且我从来没有通过身份证。

以下是我的观点的简化版本：

(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.']}]

由于我上面提到的原因，

is_valid返回FALSE。任何想法？

根据要求，以下是从is_valid检查返回的错误：

{% 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 %}

这是我的模板：

{{1}}

Answer 1

ModelFormsets需要form.id。它呈现为隐藏字段。您将需要使用两个表单集来实现它。

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

Answer 2

在这种情况下，错误消息非常清楚：您必须呈现“id”字段，否则POST将不包含每条记录的主键值。

我建议使用crispy forms并让它渲染整个formset或手动渲染模板中的字段。在第一种情况下，你会有这样的事情：

<form action="post" ...> 
    <table>
        <tbody>
           {% for form in formset %}
           <tr>
              <td>{{ form.field1 }}</td>
              <td>{{ form.field2 }}</td>
              <td class="hidden">{{ form.id }}</td>
           </tr>
        </tbody>
    </table>             
</form>

否则：

SelectQuery = self.Catalogo.select().where(self.Catalogo.c.SubcampoId == SubcampoId)

result = SelectQuery.execute()

for row in result:
  value = row['Value']

Answer 3

作为@unixo答案的附录，只需输入：

{{ form.id }}

没有任何周围的HTML标记，将在呈现模板时转换为以下内容（name会生成value，id和formset_factory的值）：

<input type="hidden" name="form-1-id" value="2" id="id_form-1-id">

只需确保将其缩进for form in formset循环中即可。

这意味着您无需添加class="hidden"，除非您对所需的隐藏字段进行了某些特殊处理。

django formset未验证，因为ID是必需的
