I'm creating this ticket to see if there is interest to implement
positional arguments in queryset filtering.
== Current situation ==
Currently the only way to use positional arguments to filter can be
either:
* Passing a single or multiple Q objects:
{{{
MyClass.objects.filter(Q(key=value))
MyClass.objects.filter(Q(key=value), Q(other_key=value))
}}}
* Passing a couple is also working (not sure if this is a happy accident)
{{{
MyClass.objects.filter((key, value))
}}}
* Combination of both is also proven to work
{{{
MyClass.objects.filter((key, value), Q(other_key=value))
}}}
== Suggestion ==
My feature suggestion is to leverage the case when a non-Q / non couple
object is passed, so it implicitly interpreted as the value for the
model's `pk`.
This could ease/simplify code by omitting `pk` when this is the only
filter used:
{{{
MyClass.objects.get(value)
# Translates into: MyClass.objects.get(pk=value)
}}}
or
{{{
MyClass.objects.filter(value)
# Translates into: MyClass.objects.filter(pk=value)
}}}
or
{{{
MyClass.objects.filter(Q(value))
# Translates into: MyClass.objects.filter(Q(pk=value))
}}}
Do you think it's worth it? It could be leveraged to simplify many
situations.
