Django表单字段分组 [英] Django form field grouping

问题描述

说我有一个包含20个字段的表单，我想将其中的10个字段（组1）放在特定的div环境中，将其他10个字段（组2）放在不同的div环境中。

Say I have a form with 20 fields, and I want to put 10 of these fields (group1) in a particular div environment and the other 10 fields (group2) in a different div environment. Something like:

<div class="class1">
{% for field in form.group1 %}
            {{ field.label}}: {{ field }}
{% endfor %}
</div>

<div class="class2">
{% for field in form.group2 %}
            {{ field.label}}: {{ field }}
{% endfor %}
</div>

有什么想法可以通过遍历字段来完成吗？更一般而言，我希望能够在许多不同的div环境和一组表单字段中执行此操作。

Any ideas how I could accomplish this by iterating over the fields? More generally, I would like to be able to do this with many different div environments and sets of form fields.

推荐答案

任何逻辑分组字段的方法会起作用...说您的表单上有一个方法可以返回您显式分组的表单字段？

Any logical way to group fields would work... say you have a method on your form that returns form fields that you explicitly group?

要保存键入内容，也许使用某种字段前缀命名方案？

To save typing, perhaps a certain field prefix naming scheme?

class MyForm(forms.Form):
    group1_field = forms.CharField()
    group1_field = forms.CharField()
    group2_field = forms.CharField()
    group2_field = forms.CharField()

   def group1(self):
        return [self[name] for name in filter(lambda x: x.startswith('group1_'), self.fields.values()]

也许在您可以过滤的字段上设置属性？

Perhaps set an attribute on the field you can filter by?

class MyForm(forms.Form):
    field = forms.CharField()
    field.group = 1

    field2 = forms.CharField()
    field2.group = 2

    def group1(self):
        return filter(lambda x: x.group == 1, self.fields.values())

    def group2(self):
        return filter(lambda x: x.group == 2, self.fields.values())

如果您也可以使用regroup标签您可以设置这些属性。

You could also use the regroup tag if you set these attributes.

{% regroup form.fields by group as field_group %}
{% for group in field_group %}
<div class="group_{{ group.grouper }}">
  {% for field in group.list %}
    {{ field }}
  {% endfor %}
</div>
{% endfor %}
