javascript - RactiveJS and Stapes model not updating -

-

i trying create filtering stapes object in ractivejs, seem 2 way binding not responding correctly update.

i can't work out going wrong thought should work without issue, have created code example here:

https://jsbin.com/sajeje/4/edit?html,output

here's pattern use using computed property filter adapted use case. couldn't stapes object directly usable result, there getallasarray() seems work:

  computed: {     filtered: function () {        var query = this.get( 'query').trim(),            users = this.get( 'users' );        return query ? users.search(query) : users.getallasarray();     }   },    data: function () {     return {       users: usersmodel,       query: ''     }   }

works sub-component pure reactive programming without need event:

<search query="{{query}}" placeholder="search users" />

updated bin here: https://jsbin.com/bomumajagu/edit?html,output

push works against stapes model:

this.get( 'users' ).push( { name: newuser } );

i getting when trying access mysql database : [firedac][phys][mysql]-314. cannot load vendor library [libmysql.dll or libmysqlld.dll] this did not happen (unchanged) code, however, have upgraded windows 10 , had reinstall delphi xe8, system configuration matter. in order try solve problem, copied both of files c:\windows\sysytem32. when did not seem work, copied them \win32\debug, generated .exe resides. i imagine doing rather stupid, can't see what. the proper solution place driver file (eg., libmysql.dll ) in application's folder, or place installation location in fddrivers.ini file: [mysql] vendor=<folder>\libmysql.dll (recent versions of documentation seem use vendorlib instead of vendor in ini file.) see rad studio documentation topics configuring drivers (firedac) , connect mysql server (firedac) more information.

so per documentation https://developer.github.com/v3/repos/releases/#list-releases-for-a-repository get /repos/:owner/:repo/releases should list relases , https://api.github.com/repos/jquery/jquery/releases should list releases in jquery project , not , why ? because repository doesn't have releases. has tags github presenting in releases page. for more clear example, see: https://github.com/hashicorp/terraform/releases which has both releases , tags showing on page, api shows releases: https://api.github.com/repos/hashicorp/terraform/releases
