How to use Translator

[Julio César Albornoz]

Dears:

I have in this script in users.py

...

...

from py4web import  Translator

T_FOLDER = os.path.join(os.path.dirname(__file__), 'translations')
T = Translator(T_FOLDER)

@action('users/showgroup', method=['POST', 'GET'])
@action('users/showgroup/<path:path>', method=['POST', 'GET'])
@action.uses(session, db, auth,Inject(createmenu=createmenu), Inject(T=T),'users/showgroup.html')    
@has_membership(['Super','sso'])
def showgroup(path=None):
    # importing datetime module for now()
    import datetime
    ls_message = T('Group')

...

...

...

In translations --> es.json

{
"Groups":{"0":"Grupos"},
"Hello":{"0":"Hola"},
}

I want  translate from English to Spanish

So I get this messages

What is wrong?

I added this instruction 

T = Translator(T_FOLDER)

T.select('es')

I can't get error, but not works translation.

[Val K]

just in case, under  trailing comma I mean last comma

I tested this (works fine):

{

"Groups":{"0":"Grupos"},

"Hello":{"0":"Hola"}

}

Dears:

After to add

T.select('es')

messages = str(T('Groups'))

or

[[=str(T('Groups'))]]

the translation works.

Regards.

The problem is that you inject T but you do not declare T as a fixture to be used. I.e. this:

@action.uses(session, db, auth,Inject(createmenu=createmenu), Inject(T=T),'users/showgroup.html')   

should be

@action.uses(session, db, auth, T, Inject(createmenu=createmenu), Inject(T=T), 'users/showgroup.html')   

Maybe when one uses T, it should inject itself. We can have that discussion on Sunday.
