[ES] Para guarda un elemento necesitamos modificar nuestra plantilla **buscador.html** para enviar la información que queremos guardar usando *POST*. Qué sencillamente será un **<form>** con las variables ocultas. En este caso lo que haremos será mostrar un botón solo visible cuando recibamos una petición *POST*. Su finalidad será realizar una petición a la página *programadas_nuevo()* con el nombre que hemos buscado.

[ES] Ahora, tendremos que crear la función para **programadas_nuevo** en **app.py**. Lo primero que le decimos es que solo puede aceptar peticiones *POST*. A continuación creamos variables para guardar la información del formulario. Después creamos el registro en la base de datos. Por último redireccionamos a la anterior página para ver el nuevo elemento.
