    3 I'm starting this page as a place to collect error messages that could stand improvement, or which are misleading or confusing in certain contexts. Most of us have had the experience of getting a "weird" message, puzzling it out (perhaps with help from django-users or #django) and then moving on. Later it can be hard to remember what the problem was.

    55This is an experiment to see if having a dedicated place to describe these cases as we encounter them can help organize a quality-control effort. Good error messages make for more productive developers. (And it helps newbies be more self-supporting, too.)

    7 Some of these may seem like quick patches but I know that others will take a bit of consideration -- that's why the wiki page rather than individual tickets.
     7Some of these may seem like quick patches but others will take a bit of consideration -- that's why the wiki page rather than individual tickets. Some are more along the lines of "Django Lint" than simple changes to error output.

    99For now, let's try dividing them into sections by major module. Within those sections suggested format is: error message, explanatory context (often important -- a message that is very helpful in one context can be confusing in another), suggested improvements/changes.
     
    2828== django.contrib.admin ==

    30 Ticket #1732 -- a problem that elicits no error message, but should.

    3634'''Suggestion:''' Check relevant Admin settings during model validation?

     36 * Ticket #1732 -- a problem that elicits no error message, but should.
     37
    3838== django.core ==

    40 Ticket #1791 suggests better error messages in cases where application dependencies are not satisfied.
     40{{{
     41EnvironmentError: Could not import settings 'foo.settings' (Is it on sys.path? Does it have syntax errors?): No module named settings
     42}}}
     43'''Context:''' Application name is same as project name, causing import problems. (See #1908 for full example.)
     44'''Suggestion:''' Given how often beginners are likely to make this mistake, it would be nice for Django to look for this conflict and warn the user.[[BR]]
