Description

No modern project uses ifequal. No one recommends it. I argue it is taking up valuable bytes in the project. Let's remove it.

Seems like a good idea, although I am afraid we may get more pushback regarding "needless deprecations" from old, large Django projects that use it. A middle ground could be to remove it from the documentation. Would you like to write to the DevelopersMailingList to see what others think?

Triage Stage: UnreviewedAccepted

The smart if tag which made ifequal redundant was introduced in Django 1.2. Really, ifequal should have been deprecated then. I agree this is a good candidate for deprecation, and I'd rather take a bit of flak for "needless" deprecations than keep tested (?) but undocumented code around forever.

Moving to "Someday/Maybe" as we have multiple complaints on the mailing list that updating projects for this removal will be too onerous to justify the cleanup.

PR. I think we should refresh discussion on the mailing list.

comment:9 by Jon Dufresne, 5 years ago

The following quick and dirty script will update a codebase to the newer {% if %} syntax. This will update files in place, so please be sure to backup your code first, preferably with SCM. You should examine the results of the diff for correctness before accepting.

find $(find -name templates) -type f -exec perl -pi -e 's/{% *ifequal +(.+?) +(.+?) *%}/{% if $1 == $2 %}/;' -e 's/{% *endifequal *%}/{% endif %}/;' -e 's/{% *ifnotequal +(.+?) +(.+?) *%}/{% if $1 != $2 %}/;' -e 's/{% *endifnotequal *%}/{% endif %}/;' {} \;

We didn't get any new complains on the mailing list, so it's time to remove them.

In 72a170b:

Fixed #25236 -- Deprecated {% ifequal %} and {% ifnotequal %} template tags.

The {% if %} tag provides all features of these tags.

Since Django 1.2 (May 17, 2010), the docs have hinted that
{% ifequal %} and {% ifnotequal %} will be deprecated in a future
Django version. Time to make it official.
