升级到1.10或1.11后，Django将URL参数命名为不再有效

Question

I have an old Django app which uses the URL template tag this way:

{% url 'smart_service.views.view_name' %}

So far it worked greatly, but after the update to version 1.10 nothing works anymore and any use made that way returns NoReverseMatch .

I can solve this problem by putting app_name = 'smart_service' into my urls.py file and by changing the url tag to this:

{% url 'smart_service:view_name' %}

This is a tedious task and very prone to errors, I'd like to avoid it unless strictly necessary.

Is the first use-case been deprecated? If not, why isn't it working anymore? Are there specific advantages in using one or the other?

Answer 1

You can't avoid this change when you upgrade to Django 1.10+.

Support for reversing urls using the dotted Python path was deprecated in Django 1.8 and removed in 1.10 .

You must change your {% url %} tags to use the view name, eg

{% url 'view_name' %}

If you add a namespace to your urls.py , for example app_name = 'smart_service' , then you must include the namespace in the {% url %} tag.

{% url 'smart_service:view_name' %}
