ActiveRecord::SchemaMigation Load (68.0ms) select 'schema_migrations'.* from 'schema_migrations'
processing by HomeController#index as HTML
Completed 500 Internal Server Error in 92ms
log writing faild. invalid byte sequence in US-ASCII 

so why i got this error and how i can solve that ??

Answer 1

I solved it now

just to solve the US-ASCII issue i added this line to the first line in my model page

#encoding: utf-8

also i added the lines

if RUBY_VERSION =~ /1.9/
    Encoding.default_external = Encoding::UTF_8
    Encoding.default_internal = Encoding::UTF_8
end

in my Gemfile

then i got another error told me use protected_attributes

so i added the line

gem 'protected_attributes'

in my Gemfile and then execute:

$ bundle
