MongoDB: Mongodump terminate called after throwing an instance of ‘std::runtime_error’

November 8, 2013 / Maciej Mensfeld

If you encounter this error:

connected to: 127.0.0.1
Mon Oct 21 10:49:30.638 DATABASE: soft_production to dump/soft_production
terminate called after throwing an instance of 'std::runtime_error'
what(): locale::facet::_S_create_c_locale name not valid
Aborted

Please add this

export LC_ALL=C
# or
export LC_ALL="en_US.UTF-8"

either in the console (for current session) or in .bashrc file.

After that you should be ready to go with:

mongodump --db soft_production

State machine gem: undefined method underscore for ActiveModel::Name

October 29, 2013 / Maciej Mensfeld

If you encounter this issue:

Failure/Error: ::Mobile::App::Talk.make!
NoMethodError:
  undefined method `underscore' for #<ActiveModel::Name:0x0000000ebae880>

When using state machine, machinist and machinist_mongo, please add this to your app/config/initializers/state_machine.rb:

# It seems that there is no underscore method on ActiveModel name
# It is added here, so it will be accessible and state machine
# can work. It should be removed after this is fixed
class ActiveModel::Name
  def underscore
    to_s.underscore
  end
end

This should be enough to make it work :)
