Displaying of API exception messages in the UI
There have been many occurrences when (especially new) contributors have made patches which propagate messages of exceptions thrown by various OpenStack APIs to users in the UI. These changes have been made in attempt to further clarify a not entirely clear UI error message. We need to improve Horizon documentation at http://

***** 10/28/2016 [clu_] The topic of error messages always seems to come up. I will update the documentations with some context.

[tsufiev 2014.12.22] Ana, are you talking about the patches like this one https:/
[akrivoka 2015.01.05] Timur, yes this is about the instances when the exception message is propagated to the UI. This poses several problems, including security and translation issues. We have discussed this many times in the Horizon community, and IIRC the consensus was that the ideal solution is to make sure that messages received from service APIs are clean and translated, so that we can simply just display them in the UI. So the solution is on the APIs side, not the Horizon side, which obviously makes it a lot harder to implement. This specific bp is just about summarizing this info and putting it somewhere in our docs, so that we can point the developers to that when they propose a patch like the one you've linked to.
