Get language setting of current node?

Question

Good morning!&nbsp;How would I get the language setting of the current node?&nbsp;Here is a screenshot of the language setting in the Node's settings in the Admin area: https://www.dropbox.com/s/1ri15f4cl7wjtun/Screenshot%202014-02-05%2010.51.53.png. How do I access this language setting via the rest api?&nbsp;To return the settings object for the node, so I can figure out what it consists of, I have this:&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp; &lt;#assign nodeSettings = rest("/categories/id/${coreNode.id}/settings") /&gt;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&lt;#assign nodeSettingsHTML&gt;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&lt;#list nodeSettings.settings.setting as setting&gt;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;console.log('${setting.name}');&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&lt;/#list&gt;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&lt;/#assign&gt;&nbsp;But it gives me this error:Freemarker template 'Hitbox' processing failedNonStringException:For "${...}" content: Expected a string or something automatically convertible to string (number, date or boolean), but this evaluated to a sequence+hash (wrapper: f.e.dom.NodeListModel):
==&gt; setting.name  [in template "Hitbox" at line 62, column 56]

The failing instruction (print stack trace for 1 more):
==&gt; ${setting.name}  [in template "Hitbox" at line 62, column 54]&nbsp;KaelaCIt was fun seeing you on BART this morning! Any tips?

Hi&nbsp;iftomkins,&nbsp;
&nbsp;
From your recent posts, it seems that you are building something similar to one of my recent projects: a language selection bar, which allows user to automatically switch to another language by a single click
&nbsp;
Just to share what I did,
&nbsp;
1) create an endpoint which can update user's profile language and expose itself as JSON.
&lt;#assign result_result = "error" /&gt;
&lt;#assign lang = http.request.parameters.name.get("lang", "")?trim /&gt;
&lt;#if user.registered &amp;&amp; lang?? &gt;
    &lt;#assign update_lang_setting = rest("/users/self/profiles/name/language/set?value=${lang}") /&gt;
    &lt;#if update_lang_setting.@status == 'success'&gt;
        &lt;#assign result_result = "success" /&gt;
    &lt;/#if&gt;
&lt;/#if&gt;
{"response":"${result_result}"}
&nbsp;2) create a component, which calls that endpoint&nbsp;and refreshes the page when user clicks a particular language tab.
LITHIUM.jQuery.ajax({
            type: "GET",
            url: "/plugins/custom/apac/apac/custom.apac.switch_language_edpt?lang=" + new_lang_code,
            dataType: "json",
            success: function (data) {
                if(data.response == "success")    {
                    window.location.reload();
                } else {
                   .........
                }
            },
&nbsp;
The output is like&nbsp;
&nbsp;

&nbsp;
btw: for&nbsp;anonymous user, you has no user profile to update, you may just need to add &nbsp;to load http://&lt;your current URL&gt;?profile.language=&lt;new language code&gt;

You can use the settings context object like this:
&nbsp;
&lt;#assign lang = coreNode.settings.name.get("profile.language", "en") /&gt;
&nbsp;
This will set lang to the language of this node with a default of English.&nbsp; 
&nbsp;
Good to see you this morning too!

Awesome, thanks Kaela!&nbsp;As we had talked about, I'm hoping to check the language setting of the current code against the user's current language setting on page load. If they are different, I'd take the language setting of the node, and change the user's language setting. I believe I can now write the logic with freemarker, but I have a question:&nbsp;I tried accessing the REST API via jQuery before launch to change the user's profile setting. This worked on stage, but it didn't work on production. Here's an example call:&nbsp;jQuery.post('/restapi/vc/users/id/' + userId + '/settings/name/profile.language/set?value=de');&nbsp;If I do the same thing with freemarker, will it work on production?&nbsp;&nbsp;&lt;#assign response = restadmin('/restapi/vc/users/id/' + userId + '/settings/name/profile.language/set?value=de')/&gt;&nbsp;&lt;#if response.hasError&gt;&lt;#-- handle error--&gt;&lt;#else&gt;&lt;#-- do cool stuff --&gt;&lt;/#if&gt;&nbsp;- Alan&nbsp;&nbsp;&nbsp;

You can make the rest call like this:"/users/id/"+user.id+"/profiles/name/language/set?value=de"The rest looks good

AWESOME!&nbsp;Just to double check, this should work on production, right?&nbsp;Also, it seems to work, except that the page needs to be reloaded after for the setting change to take effect, otherwise you end up with 2 different languages being displayed on the same page. I currently have a javascript refresh set up in the following code, but is there a Freemarker page reload command to avoid the delay? I couldn't locate it on freemarker.org or on google.&nbsp;&lt;#assign nodeLanguage = coreNode.settings.name.get("profile.language", "en") /&gt;&lt;script&gt;console.log('nodeLanguage','${nodeLanguage}');&lt;/script&gt;&lt;#assign userLanguage = rest("/users/id/${user.id}/settings/name/profile.language").value&gt;&lt;script&gt;console.log('userLanguage','${userLanguage}');&lt;/script&gt;&lt;#if nodeLanguage != userLanguage&gt;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp; &lt;#assign response = restadmin("/users/id/"+user.id+"/profiles/name/language/set?value="+nodeLanguage)/&gt;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&lt;script&gt;location.reload();&lt;/script&gt;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;#-- can this reload be in freemarker? --&gt;&lt;/#if&gt;&nbsp;&nbsp;Thanks!Alan&nbsp;&nbsp;
