No, I did not not want to translate these sentences *manually*.
The error_message=T(..) does not work, because there are some if-statements
inside the class IS_INT_IN_RANGE (and in some other classes).
One solution could be a list of error messages for these classes.
My proposal uses T as an addition parameter of the __init__ methode of class
IS_INT_IN_RANGE (and all other classes) in validators.py and therefore there
is not compatiblity problem. I can use everything as before and the
translation method (T-search) works with every "internal" error_message.
This usage of T has another advantage:
Currenty error_messages are defined twice:
- 1st inside validators.py, e.g.:
def __init__(self, expression, error_message='invalid expression'):
...
self.error_message = error_message
- 2nd on using the class, e.g.
a=IS_MATCH(...,error_message=T('invalid expression')
I think, this is against the rule "*Don't repeat yourself*"
With an additional T-parameter these lines could be written as follows:
- 1st inside validators.py, e.g.:
def __init__(self, expression, error_message='invalid expression',
T=lambda x:x):
...
self.error_message = T(error_message)
- 2nd on using the class, e.g.
a=IS_MATCH(...,T=T) # if you like the default message
Now the default error message appears only once, but could be changed by the
user.
But I don't know whether this will slow down web2py.
