Django 模板:表单字段名称作为变量? [英] Django Templates: Form field name as variable?

问题描述

如何使这个循环打印表单字段，其中 XXXXXXXX 是 ticket.id 的值?

How can I make this loop to print form fields where XXXXXXXX is the value of ticket.id?

{% for ticket in zone.tickets %}
    {{ ticket.id }}: {{ form.ticket_count_XXXXXXXX }}
{% endfor %}

所以输出是这样的......

So the output to be something like this...

1: <input ... name="ticket_count_1">
10: <input ... name="ticket_count_10">

3: <input ... name="ticket_count_3">

推荐答案

你不能在 django 模板中传递参数，所以不能.

You can't pass arguments in the django template, so no.

你需要实现一个模板标签(更痛苦)或过滤器，或者在你的视图中建立从 ticket 到 formfield 的关联(我会推荐).

You'd need to implement a template tag (more of a pain) or filter, or make the association from ticket to formfield in your view (what I would recommend).

因为我实际上并不知道 ticket 和您的表单字段之间的关系，所以我不知道最好的方法是什么，但是根据您的信息，这将有效"已经提供.

Since I don't actually know the relationship between ticket and your form fields, I can't tell what the best method is, but this would 'just work' based on the info you've provided.

# view
form = MyForm()
for ticket in zone.tickets:
    ticket.form_field = form['ticket_count_' + str(ticket.id)]

# template
{% for ticket in zone.tickets %}
    {{ ticket.id }} : {{ ticket.form_field }}
{% endfor %}
