范围不适用于for循环 [英] Range not working in for loop
问题描述
我的for循环无法正常工作,我不确定为什么。
My for loop is not working and I'm not sure why.
这是循环:
{% for i in range({{text|length}} + {{images|length}}) %}
text
和 images
是我传递给的查询集
text
and images
are querysets I have passed to the template from the view.
我得到的错误是:
django.template.exceptions.TemplateSyntaxError:'for'语句应使用格式'for x in y':for i in range({{text | length}} + {{images | length}})
django.template.exceptions.TemplateSyntaxError: 'for' statements should use the format 'for x in y': for i in range({{text|length}} + {{images|length}})
对我来说这没有意义,因为在我看来,它确实遵循错误所建议的格式。
This doesn't make sense to me, as it looks to me as if this does follow the format suggested by the error.
推荐答案
{% for i in range((text|length) + (images|length)) %}
那应该解决它。 {{}}用于其他目的。我在jinja2中遇到了自己的问题,以前从未使用过。我的循环是:
That should fix it. The {{}} are used for another purpose. I have my own problem in jinja2 and haven't used it before. My loop is:
{% for i in range(string1|length) %}
它有效
