Python django表单集可以删除标题

我是刚到django的，请容忍我

使用django formsets创建了一个模板，除了我不能为can_delete列提供标题外，它运行良好

我的Django

views.py

看起来像：

def add_expenditure(request):
    context = RequestContext(request)
    ExpFormSet = modelformset_factory(Expenditure,extra=1,max_num=10,fields=('exp_date', 'description','amount'),can_delete=True)

    if request.method == 'POST':
        formset = ExpFormSet(request.POST)
        if formset.is_valid():
            formset.save(commit=True)
            formset = ExpFormSet()
        else:
            print "errors in formset are ",formset.errors
    else:
        formset = ExpFormSet(queryset=Expenditure.objects.none())
    return render_to_response('moni/add_expenditure.html', {'formset':formset}, context)

模板格式代码如下：

<form id="expenditure_form" method="post"  action="/moni/add_expenditure/">
        {% csrf_token %}
        <table border=10>
            <tr>
                <th>Serial No.</th>
                <th><label >Date:</label></th>
                <th><label for="id_description">Description:</label></th>
                <th><label for="id_amount">Amount</label></th>
            </tr>

            {{ formset.management_form }}
            {% for form in formset %}
                <tr>
                    <td>{{forloop.counter}}</td>
                    {% for field in form %}
                        <td>  {{ field.class }} {{ field }}
                            {% if field.name == "exp_date" %}
                                 <a href="javascript:void(0)" class="todaylink" id= {{forloop.parentloop.counter0}}  >Today</a>
                            {% endif %}
                        </td>

                {% endfor %}
                </tr>
                <br>

            {% endfor %}

        </table>
        <input type="submit" name="submit" value="Create Expenditure" />
    </form>

{%csrf_令牌%}

{{forloop.counter}

{{field.class}{{field}

{%endif%}
{%endfor%}


{%endfor%}

该模板如下所示：

def add_expenditure(request):
    context = RequestContext(request)
    ExpFormSet = modelformset_factory(Expenditure,extra=1,max_num=10,fields=('exp_date', 'description','amount'),can_delete=True)

    if request.method == 'POST':
        formset = ExpFormSet(request.POST)
        if formset.is_valid():
            formset.save(commit=True)
            formset = ExpFormSet()
        else:
            print "errors in formset are ",formset.errors
    else:
        formset = ExpFormSet(queryset=Expenditure.objects.none())
    return render_to_response('moni/add_expenditure.html', {'formset':formset}, context)

我想要的是有一个删除复选框的标题。。就在数量旁边。我试着再添加一个标题，但它似乎没有按预期工作。有人能提供一些建议吗。。下面是添加一个标题后的外观

    <form id="expenditure_form" method="post"  action="/moni/add_expenditure/">
        {% csrf_token %}
        <table border=10>
            <tr>
                <th>Serial No.</th>
                <th><label >Date:</label></th>
                <th><label for="id_description">Description:</label></th>
                <th><label for="id_amount">Amount</label></th>
                <th><label for="id_delete">Delete</label></th>
            </tr>

            {{ formset.management_form }}
            {% for form in formset %}
                <tr>
                    <td>{{forloop.counter}}</td>
                    {% for field in form %}
                        <td>  {{ field.class }} {{ field }}
                            {% if field.name == "exp_date" %}
                                 <a href="javascript:void(0)" class="todaylink" id= {{forloop.parentloop.counter0}}  >Today</a>
                            {% endif %}
                        </td>

                {% endfor %}
                </tr>
                <br>

            {% endfor %}

        </table>
        <input type="submit" name="submit" value="Create Expenditure" />
    </form>

{%csrf_令牌%}

有关如何在“删除”复选框上方创建此标题的任何建议？

问题在于

{% for field in form %}
    <td>  {{ field.class }} {{ field }}
        {% if field.name == "exp_date" %}
        <a href="javascript:void(0)" class="todaylink" id= {{forloop.parentloop.counter0}}    >Today</a>
        {% endif %}
    </td>
{% endfor %}

{%用于表单%]中的字段
{{field.class}{{field}
{%if field.name==“exp_date”%}
{%endif%}
{%endfor%}

这将创建5个TD，标题中有4个TD

请试试这个

<tr>
            <th>Serial No.</th>
            <th><label >Date:</label></th>
            <th><label for="id_description">Description:</label></th>
            <th><label for="id_amount">Amount</label></th>
            <th></th>
            <th><label for="id_delete">Delete</label></th>
</tr>

序列号。

也可以在删除前删除元素复选框
