Only if the --check flag is on. The --check flag indicates that one is explicitly checking that all model changes have migrations. A non-zero exist status indicates that migrations were missing. If you feel the help text could be improved to communicate this, I can work towards that. > Why do you object to using a ! to communicate this? With the --check flag or the --exit flag? I think I covered this in the OP. But just to clarify: My use case: Continuous integration server check's developers' commits for correctness. One aspect of correctness is that all model changes have migrations. In shell scripting and CI servers an exit status of 0 indicates true/pass and an exit status of non-zero indicates false/failure. Therefore, the command should return 0 when everything is OK and correct and non-zero otherwise. Commits are correct when all model changes are accounted for. The current --exit behavior, returns non-zero when everything is correct. To account for this in CI, one must negate the exit status with !, this goes against conventional behavior. Further, if something goes terribly wrong and there is an unhandled exception, negating the exit status will make the CI stage appear to pass. This is backwards! CI can't tell the difference between "all changes accounted for" and "Python had an unhandled exception".
