This is one of a class of changes I'm interested in making, so please also
comment on if developer experience/error message improvements like this
are wanted in general.
I recently started a new Django project and got frustrated at tiny
mistakes I made that were difficult to find because of opaque error
messages.
Currently, writing this:
{{{
#!python
def render_view_missing_request(request):
return render('shortcuts/render_test.html')
}}}
leads to:
{{{
TypeError: render() missing 1 required positional argument:
'template_name'
}}}
which is very confusing because the developer ''did'' provide the template
name.
Writing another common variation:
{{{
#!python
def render_view_missing_request(request):
return render('shortcuts/render_test.html', {'foo': 'FOO'})
}}}
leads to:
{{{
TypeError: join() argument must be str or bytes, not 'dict'
}}}
which is easier to figure out given the stack trace, but still unhelpful
to a newcomer.
