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
如何使此循环打印表格字段,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">
12: <input ... name="ticket_count_12">
3: <input ... name="ticket_count_3">
推荐答案
您不能在django模板中传递参数,所以不行。
You can't pass arguments in the django template, so no.
您需要实现一个模板标签(更多的是痛苦)或过滤,或者从票据
to formfield
在你的意见(我会推荐什么)。
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).
由于我实际上不知道票之间的关系
和您的表单字段,我无法确定最好的方法是什么,但这将根据您提供的信息正常工作。 p>
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 %}
