Do you mean the error messages from a model instance? You can just use  
ruby’s standard file io methods to read and write a yaml file:

File.open(‘errors.yml’, ‘w’) do |out|  
out.write(my\_obj.errors.full\_messages.to\_yaml)  
end

to read it back in:  
errors = YAML.load\_file(‘errors.yml’)

hi Evan

Thank you for spending your precious time  
As i am very new to ruby on rails can i find any sample application on  
the above  
because i have some 50 models and all the error should be in one file  
e.g errors.yml

Even i dont know where to put this errors.yml file

Please guide me
