custom error messages

[Burak Cankurtaran]

Hi,

I'm only using validatish and schemaish in my application.
I want to be able to display any validation errors using
custom messages stored in the schemaish structure.
I could change the default messages in validatish but
then there is no schema dependence.

Has anyone extended schemaish to support this?

I think formish supports this but I am not
using formish. I'm a new user so not quite sure.

Thanks
Burak

I have found I always need to override the default error messages. I simply wrap the validator in a class that provides the message I want:

class Message(object):
    def __init__(self, context, message):
        self.context = context
        self.message = message

    def __call__(self, data):
        try:
            self.context(data)
        except validatish.Invalid:
            raise validatish.Invalid(self.message)

It's really validatish that handles the error messages.

It's not something I've ever done but you should be able to pass a dict of custom error messages to any validatish function or validator instance. For example:

>>> import validatish

>>> validatish.is_in_range(10, min=18)

Traceback (most recent call last):

  File "<stdin>", line 1, in <module>

  File "/home/matt/src/jdi/profiled/libs/validatish/validatish/validate.py", line 281, in is_in_range

    raise Invalid(error)

validatish.error.Invalid: must be greater than or equal to 18

>>> validatish.is_in_range(10, min=18, messages={'greater-than': 'You must be %(min)s or older'})

Traceback (most recent call last):

  File "<stdin>", line 1, in <module>

  File "/home/matt/src/jdi/profiled/libs/validatish/validatish/validate.py", line 281, in is_in_range

    raise Invalid(error)

validatish.error.Invalid: You must be 18 or older

Thanks Daniel and Matt.

Just quickly, I just unsuccessfully tried Matt's suggestion;

>>> validatish.is_in_range(10, min=18, messages={'greater-than': 'You must be %(min)s or older'})
Traceback (most recent call last):
File "<stdin>", line 1, in <module>

File "build/bdist.linux-x86_64/egg/validatish/validate.py", line
286, in is_in_range

validatish.error.Invalid: must be greater than or equal to 18

I think there might be a difference in the library versions. Matt the
exception is raised
on line 281 for your version and line 286 for my version.

I used easy_install to install the library - validatish-0.6.4-py2.7.egg

After I get some sleep I'll look at both solutions properly.

Thanks
Burak

Sorry, that's my fault. I fixed that particular validation function in the git repository but there's been no release since. It's just typical that I chose the only validation function that was broken for the example :/.

I'll try to get a new release out, but you can get the latest source from https://github.com/ish/validatish/tree/ until then.
