[英]Django: Problem with passing parameters from a template {% url %} to a view
I have this urlpath:我有这个网址路径:
path('download/<str:fpath>/<str:fname>', views.download, name='download'),
And this is the view:这是观点:
def download(request, fpath, fname):
# some code
In template, I have this href tag and I want to pass those strings as arguments to the download
view.在模板中,我有这个 href 标签,我想将这些字符串作为参数传递给
download
视图。
<a href="{% url 'download' 'lms/static/lms/files/homework/Math 1/3/3' 'hmm.pdf' %}">click me</a>
But I get this error:但我得到这个错误:
NoReverseMatch at /
Reverse for 'download' with arguments '('lms/static/lms/files/homework/Math 1/3/3', 'hmm.pdf')' not found. 1 pattern(s) tried: ['download/(?P<fpath>[^/]+)/(?P<fname>[^/]+)\\Z']
How can I fix this?我怎样才能解决这个问题?
Url arguments of type str
cannot contains /
characters. str
类型的 URL 参数不能包含/
字符。 You can see this in the error message which has translated your <str:fpath>
to a regex:您可以在将您的
<str:fpath>
转换为正则表达式的错误消息中看到这一点:
tried: ['download/(?P<fpath>[^/]+)/(?P<fname>[^/]+)\\Z']
You should use a path
converter for your case (see here ).您应该为您的案例使用
path
转换器(请参见此处)。
For example:例如:
path('download/<path:fpath>/<str:fname>', ...)
