Question

Can’t seem to find this anywhere:

Module::ModelClassOne.all.each do
  Module::ModelClassTwo.all.each do
    # get an error of undefined constant ModelClassTwo
  end
end

What gives? I have tried a few different alternatives:

Module::ModelClassOne.all.each do
  ::Module::ModelClassTwo.all.each do
    # get an error of undefined constant ModelClassTwo
  end
end

and

Module::ModelClassOne.all.each do
  ModelClassTwo.all.each do
    # get an error of undefined constant ModelClassTwo
  end
end

and

Module::ModelClassOne.each do
  ::ModelClassTwo.each do
    # get an error of undefined constant ModelClassTwo
  end
end

Nothing works and it’s making me crrrrrrazzzzzy.

Answer 1

The each method doesn’t redefine the execution context so this is probably a case of ModelClassTwo not being defined as you expect.

Make sure ModelClassTwo is actually loaded. You may have forgotten to require that file.
