问题
When I try to run heroku run rake db:migrate in my application, I get the following error
"\xC4" from ASCII-8BIT to UTF-8
with a stacktrace of
/app/.bundle/gems/ruby/1.9.1/gems/rake-0.9.2.2/lib/rake/application.rb:150:in `write' /app/.bundle/gems/ruby/1.9.1/gems/rake-0.9.2.2/lib/rake/application.rb:150:in `puts' /app/.bundle/gems/ruby/1.9.1/gems/rake-0.9.2.2/lib/rake/application.rb:150:in `display_error_message' /app/.bundle/gems/ruby/1.9.1/gems/rake-0.9.2.2/lib/rake/application.rb:142:in `rescue in standard_exception_handling' /app/.bundle/gems/ruby/1.9.1/gems/rake-0.9.2.2/lib/rake/application.rb:132:in `standard_exception_handling' /app/.bundle/gems/ruby/1.9.1/gems/rake-0.9.2.2/lib/rake/application.rb:88:in `top_level' /app/.bundle/gems/ruby/1.9.1/gems/rake-0.9.2.2/lib/rake/application.rb:66:in `block in run' /app/.bundle/gems/ruby/1.9.1/gems/rake-0.9.2.2/lib/rake/application.rb:133:in `standard_exception_handling' /app/.bundle/gems/ruby/1.9.1/gems/rake-0.9.2.2/lib/rake/application.rb:63:in `run' /app/.bundle/gems/ruby/1.9.1/gems/rake-0.9.2.2/bin/rake:33:in `' /app/.bundle/gems/ruby/1.9.1/bin/rake:19:in `load' /app/.bundle/gems/ruby/1.9.1/bin/rake:19:in `'
I've tried setting encoding manually in config/environment.rb via
Encoding.default_external = Encoding::UTF_8
Encoding.default_internal = Encoding::UTF_8
But it doesn't seem to help. The problem might be, that I'm using slim as a templating engine with many unicode characters directly in the templates, but I'm not sure if there's a better way of doing that.
回答1:
Simply add this to the top of your file
# encoding: UTF-8
this error is frequent with migration when you insert data. For exemple I've got this with a simple migration adding Québec
Province.create(:name => 'Québec (Canada)')
