Question

如何创建此表使用formset和extra = 3？

表：

| my name first column | second column | third column | fourth column |

| formset1.field1.label | formset1.field1 | formset2.field1 | formset3.field1 |

| formset1.field2.label | formset1.field2 | formset2.field2 | formset3.field2 |

| formset1.field3.label | formset1.field3 | formset2.field3 | formset3.field3 |

| formset1.field4.label | formset1.field4 | formset2.field4 | formset3.field4 |

在视图中我创建标准formset：

def my_view(request, id_object):
    getobject = get_object_or_404(Model, id=id_object)
    FormSetInit = inlineformset_factory(Model, Model2, form=FormModel2, extra=3)
    FormSet = FormSetInit(instance=getobject, prefix='model2')
    response = {}
    response['Formset'] = FormSet
    return render_to_response('my_template.html', response)

在模板'my_template.html'中，我尝试使用此：

<table>
{% for form in Formset %}
  {% if forloop.counter == 1 %}
    {% for field in form %}
      {% if forloop.counter < 8 %}
        <tr>
          <td class="first">{{ field.label }}</td>
          <td>{{ field }}</td>
          <td>{{ field }}</td>
          <td class="last">{{ field }}</td>
          {% if forloop.counter !=  7 %}
            </tr>
          {% endif %}
      {% else %}
        {{ field }}
        {% if forloop.last %} </tr> {% endif %}
      {% endif %}
    {% endfor %}
  {% endif %}
{% endfor %}
</table>

但这不是一个好主意..：/

我也遇到了这方面的麻烦，但设法让它在https://docs.djangoproject.com/en/dev/topics/forms/?from=olddocs#displaying-a-form-using-a-template

的帮助下工作了

无论如何，这是你可以尝试的模板，它基本上遍历每个表单：

<table>
    <thead>
        {% for form in Formset.forms %}
            {% if forloop.first %}
                {% for field in form %}
                    <th>{{ field.label_tag }}</th>
                {% endfor %}
            {% endif %}
    </thead>
    <tbody>
            <tr>
                {% for field in form %}
                    <td>{{ field }}</td>
                {% endfor %}
            </tr>
        {% endfor %}
    </tbody>
</table>

希望有所帮助！不确定它是最好的方式，但它确实有效！

<table id='supertable' border=1>
<tr>
{% for form in formset %}
    {% if forloop.counter = 1 %}    
    <td>
        <table>
        {% for field in form.visible_fields %}
            <tr><td style="background: cyan; line-height:1; white-space:nowrap;" >{{ field.label_tag }}</td></tr>
        {% endfor %} 
        </table>
    </td>
    {% endif %}
    <td>
        <table>
        {% for field in form.visible_fields %}
            <tr><td style="background: pink; line-height:1; white-space:nowrap;" >{{ field}}</td></tr>
        {% endfor %} 
        </table>
    </td>
{% endfor %} 
</tr>
</table>

在我尝试实现相同的目标并最终以脆弱的形式实施之后提供更新的答案

形式：

from crispy_forms.helper import FormHelper, Layout
...

class MyForm(forms.ModelForm):

    class Meta:
        model = MyModel
        fields = ['field1', 'field2', 'field3']


MyFormSet = modelformset_factory(MyModel, form=MyForm, extra=0)


class MyFormSetHelper(FormHelper):
    def __init__(self, *args, **kwargs):
        super(MyFormSetHelper, self).__init__(*args, **kwargs)
        self.layout = Layout(
            'field1',
            'field2',
            'field3'
        )
        self.template = 'bootstrap/table_inline_formset.html'

查看：

formset = MyFormSet(queryset=my_qs)
helper = MyFormSetHelper()
context = {'formset': formset, 'helper': helper}
return render(request, 'my_template.html', context)

模板：

{% extends "base.html" %}
{% load crispy_forms_tags %}

{% block content %}

<form action="" method="post">
    {% csrf_token %}
    {% crispy formset helper %}
</form>

{% endblock content %}

如何在模板django中渲染formset并创建垂直表？
