Hello Michael!
Unfortunately, Erlang Web does not have the autodetection mechanism
of the browser's language: the language you want to be used in your
service has to be set up manually (or, in fact, when you have the IP
set up you can always use some geolocator).
Designing and deciding what headers/browser's information should be
accessible within framework is not a trivial task though. We have to
find some golden mean: or parametrize somehow the granularity.
The language of the translation is chosen in the following steps:
1. stored in "session:lang"
2. from the default_language clause in project.conf
3. set to 'en'
In your case, neither first option, nor the second one is found, so
the translation is set up to 'en'.
Moreover, you are trying to modify the 'e_dict' content by inserting
some values using ets:insert. The main idea of the request dictionary
is its lifetime is limited to the request time only. That means you can
not access its content before or after request processing. Moreover,
the new request dictionary is created per request. The only
non-transient field of the dictionary is "session" (but it is going to
be deleted after some timeout).
Updating the e_dict ets table will not take effect anyhow - try to handle
the language setting process within the controller function:
wpart:fset("session:lang", 'es-es').
