Rails // ActionController::ParameterMissing error

I am getting an ActionController::ParameterMissing in FarmersController#create error. I am just doing a basic user login setup. A lot of the similar help out there suggests I may have a spelling, or a plural vs singular mix up. I can not seem to find any such discrepancy.

The error discription: param is missing or the value is empty: farmer

Thank you in advance. Much appreciated.

I went back and reset everything. Somewhere along the way, the error stopped getting triggered. To the best of my knowledge, the code above is more or less correct for what I want to do.
