forloop should have an accessor for the total count of the loop

[Jonathan Ströbele]

The forloop has no way for accessing the total loop iteration count, though the ​length of the values being iterated is already known on the logic for building up the forloop variable.

I propose to expose this count on the forloop variable, i.e. like: forloop.total. I think it can be helpful to have this information available inside a loop if needed (this also the case for example in the ​Laravel/Blade loop variable):

{% for val in values %}
  {{ forloop.total }}
{% endfor %}

I prepared a patch here and can send it of as a PR if it's okay: ​https://github.com/stroebjo/django/commit/0a6233bcd9f2356a2b7b646ad4448ee313dc4d43

I suppose this is possible already with something like {{ forloop.counter|add:forloop.revcounter }}
I do however think this would be a nice addition, feels at the least more readable/discoverable and it's good to see that other frameworks have come to that conclusion

Once you submit a PR to the project, can you update the flags here? Note that it would need a .. versionchanged note and a release note :)

Hi thanks for the reply,

I noticed that Jinja2 also has this ​feature, they call it .length . Would that be more appropriate for Django as well? Like forloop.length or is .total fine (the other keys are named differently anyways).

Regarding the release:

• I put it into the release of 5.1.7, is this fine?
• I tried to unterstand how to markup the .. versionchanged, but here I'm not sure if I did this correctly regarding the forloop table.

I prepared the PR and sent it of, if I should change something please let me know! :)
