Hi All,
I recently discovered that there is no way in the Django template syntax to
access all valid items of a dict. For example, as I understand it, it is
impossible to access the only item of this dict:
my_dict = {"_key": "value"}
This is despite this dict being perfectly valid and not breaking any Python
conventions. I also discovered that possible work arounds like this
ticket<https://code.djangoproject.com/ticket/3371> have
been set to won't fix because they are considered to be out "out of scope
for the built-in template engine".
I'd like to request that this issue be re-examined. It
is extremely frustrating not being able to access perfectly legal dict
items by key using the Django template engine. One possible reason for
the preceding _ rule also applying to dict lookups in the variable syntax
mentioned on IRC was to make it simpler for template coders who have no
real knowledge of Python (and the convention that variables or functions
prefixed with _ are considered private). I can't see how enforcing this
rule makes it any simpler for them especially since it isn't actually
mentioned in the template syntax documentation and generally these people
wouldn't be constructing the context for the template in the view. All it
really seems to do is add more complexity for the view programers without
any real increase in simplicity for template writers who are blissfully
unaware.
Interested to hear the reasoning behind the original design decision and
how people are finding it in practice.
Cheers
