Change users language preference with REST API

Hello heavenerp ,

With JavaScript, able to change the user's language preference using the REST API. Below is the code that demonstrates how to do this:

<script>
const options = {
    method: 'PUT',
    headers: {accept: 'application/json', 'content-type': 'application/json'},
    body: JSON.stringify({
        data: {
            type: 'user',
            personal_data: {
                list_item_type: 'personal_datum',
                items: [
                    {type: 'personal_datum', id: 'language', value: 'en'}
                ]
            },
        }
    })
};

fetch('https://community-domain/api/2.0/users/user-id', options)
.then(response => response.json())
.then(response => console.log(response))
.catch(err => console.error(err));

</script>

Hi heavenerp 

is this for a front-end custom component? If so - have you considered using an Endpoint which uses an elevated privilege rest call (using restadmin) and then sets to the desired value?

Of course - you would want to make sure that you do appropriate checks (such as for example, is the endpoint trying to set the profile language for the same user currently logged in? or is the language value a valid one? etc...) because of the usage of restadmin - which requires extra care.

Thanks,

Hi heavenerp,

I had completed a similar function weeks ago with Endpoint (like what PaoloT  mentioned). more details can be found with http://lithosphere.lithium.com/t5/developers-discussion/Get-language-setting-of-current-node/m-p/128715#M4922

this week, I realised that there could be a simpler approach with "Page Initalization" (more details with Page Initalization can be found with http://lithosphere.lithium.com/t5/developers-discussion/Is-it-possible-to-make-a-redirect-with-REST-or-Freemarker/m-p/123591#M4666), after some simple test, I found that it works.

in short, we can just use the same hyperlink as you did for non-logged in users.

<a href="/t5/help/faqpage?profile.language=de">Click here to read this page in German</a>

and in "Page Initalization", you can have something like this

<#assign lang = http.request.parameters.name.get("profile.language", "")?trim />
<#if user.registered && lang?has_content && (lang?length > 0) >
    <#assign cur_lang = settings.name.get("profile.language", "") />
    <#if cur_lang != lang >
        <#assign update_lang_setting = rest("/users/self/profiles/name/language/set?value=${lang}") />
        ${http.response.setRedirectUrl(http.request.url)}
        <#-- Refresh the URL -->
    </#if>
</#if>

note: http.response.setRedirectUrl is necessary as we need to re-load the language in user session.

I hope that this helps.
