[Erlangweb-users] about Template Engines

[AndyChow <diu...@16...>]

hi,
i only use signal tpl file for app in normal times,  tpl works good.
when i read template engine from http://wiki.erlang-web.org/TemplateEngine, following the document, i build the same tpl files, and i use wpart_gen:load_tpl api for load tpl files, like http://www.erlang-web.org/step1.html, when i build the app and run it. it give me following error:

reason: {{badmatch,{error,enoent}},
         [{wpart_gen,load_tpl,3},
          {lists,foreach,2},
          {websso,test,1},
          {e_mod_gen,controller,3},
          {e_mod_yaws,'-out/1-fun-0-',1},
          {e_mod_yaws,with_formatted_error,1},
          {e_mod_yaws,out,1},
          {yaws_server,deliver_dyn_part,8}]} 

this is my a part of load tpl code:
Tpls = [{base, "test/base.html"},
        {half_filled, "test/half_filled.html"},
            {filled, "test/filled.html"}
            ],
    
   lists:foreach(fun({Name, Path}) ->
                wpart_gen:load_tpl(shop, Name, Path)
              end, Tpls), 

there is something wrong? please give a whole example for template engines, thanks.:)
