使用model_formset的Django表单未提交

Question

我正在尝试创建一个屏幕来显示我的应用程序中的所有用户，然后能够为用户更新显示的字段。基本上是用户的管理员视图。我希望能够通过点击提交一次更新多个用户。

我使用 modelformsets 来完成这项工作，并从 answer to another question 复制了 html，以便内联显示表单（见下文）。

HTML模板：

               <div class="card-body">
              <form action="{% url 'bugtracker:users' %}" method='POST'>
                <table id="formset" class="form">
                  {{ formset.non_form_errors.as_ul }}
                  {{ formset.management_data }}
                  {% csrf_token %}
                  {% for form in formset.forms %}
                  {% if forloop.first %}
                <thead><tr>
                  {% for field in form.visible_fields %}
                  <th>{{ field.label|capfirst }}</th>
                  {% endfor %}
                </tr></thead>
                {% endif %}
                <tr class="{% cycle 'row1' 'row2' %}">
                  {% for field in form.visible_fields %}
                  <td>
                    {# Include the hidden fields in the form #}
                    {% if forloop.first %}
                    {% for hidden in form.hidden_fields %}
                    {{ hidden }}
                    {% endfor %}
                    {% endif %}
                    {{ field.errors.as_ul }}
                    {{ field }}
                  </td>
                  {% endfor %}
                </tr>
                {% endfor %}
              </table>
              <button class="btn btn-primary" type="submit">Submit</button>
            </form>
            </div>

观点：

@login_required
def users(request):
    # users = User.objects.all()
    UserFormSet = modelformset_factory(User,fields=('username','first_name','last_name','email','is_contributor','is_projectmanager','is_administrator'), extra=0)
    if request.method == 'POST':
        formset = UserFormSet(request.POST or None)
        print(formset)
        if formset.is_valid():
            formset.save(commit=True)
            messages.success(request,f"save successfull")
            return HttpResponseRedirect(reverse("bugtracker:users"))
        else:
            print("error")
            for form in formset:
                print(form.cleaned_data) 
            messages.success(request,f"error")
            return HttpResponseRedirect(reverse("bugtracker:users"))

    formset = UserFormSet()
    context = {
        # 'users':users,
        'formset':formset,
    }
    return render(request, 'bugtracker_app/users.html', context)

我发现表单无效，因此没有保存。 form.cleaned_data 如下所示：

<tr><td colspan="2"><ul class="errorlist nonfield"><li>(Hidden field TOTAL_FORMS) This field is required.</li><li>(Hidden field INITIAL_FORMS) This field 
is required.</li></ul><input type="hidden" name="form-TOTAL_FORMS" id="id_form-TOTAL_FORMS"><input type="hidden" name="form-INITIAL_FORMS" id="id_form-INITIAL_FORMS"><input type="hidden" name="form-MIN_NUM_FORMS" id="id_form-MIN_NUM_FORMS"><input type="hidden" name="form-MAX_NUM_FORMS" id="id_form-MAX_NUM_FORMS"></td></tr>

这是我第一次使用模型表单集或一般表单集。有人可以告诉我为什么我的表单没有正确保存，以及如何修改我的代码以保持我的表格的形状，但在我点击提交时仍然保存所有记录？

Answer 1

我找到了答案：

在我输入的模板中，{{ formset.management_data }} 应该是 {{ formset.management_form }}。我使用的文档是here

我还必须将{{ formset.management_form }} 移动到表格标签中。

完整的工作 HTML 在这里：

          <form action="{% url 'bugtracker:users' %}" method='POST'>
            <table id="formset" class="form">
              {{ formset.management_form }}
              {{ formset.non_form_errors.as_ul }}
              {% csrf_token %}
              {% for form in formset.forms %}
                {% if forloop.first %}
                <thead><tr>
                  {% for field in form.visible_fields %}
                    <th>{{ field.label|capfirst }}</th>
                  {% endfor %}
                </tr></thead>
                {% endif %}
              <tr class="{% cycle 'row1' 'row2' %}">
                {% for field in form.visible_fields %}
                <td>
                  {# Include the hidden fields in the form #}
                  {% if forloop.first %}
                    {% for hidden in form.hidden_fields %}
                      {{ hidden }}
                    {% endfor %}
                  {% endif %}
                  {{ field.errors.as_ul }}
                  {{ field }}
                </td>
                {% endfor %}
              </tr>
              {% endfor %}
          </table>
          <button class="btn btn-primary" type="submit">Submit</button>
        </form>
