How can I print query set element in Django Template?

问题

I have this code in my template file

{{markets|getSpiderItem:spider.id}}

Mysql has market_timezone and market_location and it connects to another table with spider_id so I filtered as follow:

@register.filter
def getSpiderItem(datas, spider_id):
    return datas.filter(spider=spider_id)

I am getting this output:

<QuerySet [{'market_timezone': 'Turkey', 'market_location': 'Nigde'}]>          

I want to print this QuerySet item on Django Template separately.

This function has already 2 for loop so I want to print just 1 time. I don't wanna use for loop like this:

{% for market in markets|getSpiderItem:spider.id %}

I want something like this but I couldn't figure out:

For Example:

{{markets|getSpiderItem:spider.id|market_timezone}} # I don't know the true way.

回答1:

this is ok

{{markets|getSpiderItem:spider.id|market_timezone}}

modify getSpiderItem()

@register.filter
def getSpiderItem(datas, spider_id):
    return iter(datas.filter(spider=spider_id))

define filter market_timezone():

@register.filter
def market_timezone(iitem):
    return next(iitem).market_timezone

Expected content: Turkey
