I have my messages.properties like this:
tablas.menu.paises=Pa\u00EDses
tablas.menu.regiones=Regiones
tablas.menu.anhos=A\u00F1os
tablas.menu.universidades=Universidades
tablas.menu.usuarios=Usuarios
In the .html I have a menu showing each item with th:each:
<li class="nav-item" th:each="menu : ${menus}">
<a th:text="#{tablas.menu.${menu.nombre}}"></a>
</li>
For each "menu in ${menus}", menu.nombre has the values paises, regiones, anhos... But thymeleaf doesn't recognise the model variable inside the #{}, and this it is giving me in the view the error when it doesn't find the message:
??tablas.menu.${menu.nombre}_es_ES??
Configuration is ok, if I change the call for #{tablas.menu.regiones} I get 'regiones' and so. Is there any way to call a message from messages.properties dynamically using a model variable like this?
Thanks.
You can use the #messages
utility object for this:
<a th:text="${#messages.msg('tablas.menu.' + menu.nombre)}" />
Or you can create the string using literal substitution:
<a th:text="#{|tablas.menu.${menu.nombre}|}" />
I would recommend using preprocessing only as a last resort, as bad values can cause runtime errors. (Although they do work for this.)
