Django: create HTML input array using a django form
提问by Brant
I am trying to automate the creation of something like this:
我正在尝试自动创建这样的东西：
<input type='text' name='asdf[]' />
<input type='text' name='asdf[]' />
<input type='text' name='asdf[]' />
By cycling through a range in the form. I've been trying things like this, along with several other variations:
通过在窗体中循环遍历一个范围。我一直在尝试这样的事情，以及其他一些变化：
# in a model class
for i in range(1, prim+1):
self.fields['asdf'] = forms.CharField(label=i)
# in the template
<form action='#' method='post'>
{{form.as_p}}
</form>
But I haven't had any luck though.
但我没有任何运气。
How can I go about automating an array of inputs?
我怎样才能自动化一系列输入？
** edit ** To clarify, eventually I need to be able to access the fields in the template like this:
** 编辑 ** 澄清一下，最终我需要能够像这样访问模板中的字段：
{% for input in form.fields.asdf %}
{{input}}
{% endfor %}
Which would then hopefully get me the original input list shown above...
然后希望让我得到上面显示的原始输入列表......

It looks like I can do what I need to do by breaking the form into multiple formsets...
看起来我可以通过将表单分成多个表单集来做我需要做的事情......
http://docs.djangoproject.com/en/dev/topics/forms/formsets/#topics-forms-formsets
http://docs.djangoproject.com/en/dev/topics/forms/formsets/#topics-forms-formsets
Then, I should be able to access each formset individually from the template, wrapping all of them into one
然后，我应该能够从模板单独访问每个表单集，将它们全部包装成一个

Jacob Kaplan-Moss (co-author of Django) recently posted a great article for handling dynamic forms, which should solve your problem in a preferred way: http://jacobian.org/writing/dynamic-form-generation/
Jacob Kaplan-Moss（Django 的合著者）最近发表了一篇关于处理动态表单的精彩文章，它应该可以以首选方式解决您的问题：http: //jacobian.org/writing/dynamic-form-generation/
He's using the same method that Felix suggests, but it's worth reading the whole article to get a better grasp on the concept.
他使用的方法与 Felix 建议的方法相同，但值得阅读整篇文章以更好地掌握这个概念。
Using the asdf[]technique is sloppy, because then you have to deal with ordering. It's also not the standard practice.
使用该asdf[]技术是草率的，因为那时您必须处理排序。这也不是标准做法。
Edit:
编辑：
To handle the situation where you need to detect when you hit these dynamic fields:
要处理需要检测何时点击这些动态字段的情况：
{% for input in form.fields %}
{% ifequal input.label 'asdf' %}
{{ forloop.counter }}: {{input}}<br />
{% endifequal %}
{% endfor %}
回答by Felix Kling
It should be more like e.g.:
它应该更像是例如：
# in a model class
for i in range(1, prim+1):
self.fields['asdf_%s' % i] = forms.CharField(label='Label %i' % i)
But it very depends on what you want to achieve.
但这在很大程度上取决于您想要实现的目标。
