Is there a web end point to switch OpenMRS locale?

Hi!

Is there a way to switch the OpenMRS session locale using a web service?

Is this of any help? Changing OpenMRS site language via REST

@mksrom

After skimming that other thread (and reading my last post), I think the short answer is that this isn’t supported yet, but we should definitely add it. Want to go ahead and add this in the webservices.rest module?

Maybe we want:

  • POST .../session/locale to set the session locale
  • POST .../user/locale (set your own user’s default language)
  • this may not be possible given our current url mappings
  • POST .../user/{uuid}/locale (set a different users’s default language, if you have privileges)

Do you need all of these?

Thanks @darius. I would only need:

POST .../session/locale to set the session locale

Context: The idea behind is we would like the OpenMRS metadata to be translated in the session locale and being sent back localized to clients. Currently, metadata are not i18ned, they display in only one language (Bahmni Apps locale not syncing OpenMRS locale (and vice versa)?), so as a temporary solution, we are thinking of replacing the metadata values by an i18n message, and wrap all ‘get’ services to return translated metadata strings. For this we need OpenMRS to be aware of the locale selected by the web client.

We think this through a bit more and then yes, we can develop and add it to webservices.rest

Okay, as soon as you want, just create a ticket and implement it. This should surely be supported by the REST API.

Is GET /session/locale already implemented? And is there a way to get available locales?

With these three – (1) get available locales, (2) get current locale, and (3) set locale – we could finally implement locale setting in our new UIs instead of forcing people to the legacy UI to change locales.

Why introduce the /session/locale end point? I would think locale and availableLocales should be included in the /session resource

No it’s not. The way to get this now is get the global property using: GET .../systemsetting/locale.allowed.list

I would expect GET .../session/locale to get the current session locale.

@burke do you have a suggestion for how to expose server configuration settings like “all available locales”? (The only precedent we have for doing anything other than just global properties via the systemsetting resource is the orderentryconfig resource which I implemented at some point and never asked for permission/feedback about.)

I guess I don’t have a strong opinion about whether one should do:

POST .../session
{ "locale": "en" }

or

POST .../session/locale
{ "value": "en" }

Just to be sure before creating the ticket, are we talking about SessionController?

Yes, SessionController is the one responsible for processing requests for the session ‘resource’.

So that would be the way to set the user locale to ‘en’:

POST .../session
{ "locale": "en" }

@wyclif, how would you envision (1) and (2)? Would this be ok?

GET .../session
{ "locale": "current" }
GET .../session
{ "locale": "all" }

GET …/session

{ "locale": "en", "availableLocales": ["en", "it"] }

Why would you pass the "en" when trying to get the current locale?

@mksd I think you’re suggesting that we do a GET that includes body content, to get the current locale or list of locales. I don’t like that (and I think Wyclif was confused by that, and he’s suggesting the return from a GET).

FYI right now when I GET the session resource I get

}

It would make perfect sense to add the current locale as just one more property here.

I would rather put “get available locales” in some sort of common “get system configuration” endpoint, but I haven’t thought through what it would look like.

@mksd that was the return value as @darius said which would also include the other fields on the session resource.

Ok got it, thanks both. I’ll create the ticket as soon as possible.
