I have a one to many association between jobs and companies and it works fine. In the job form view I have text_field for the company name with an autocomplete feature. The autocomplete works fine but the find_or_create_by don't create a new company if I put a company name that doesn't exist in the autocomplete list.

  def company_name
    company.try(:name)
  end

  def company_name=(name)
    @company = Company.find_or_create_by(name: name)
  end

Please take a look at this answer.

What used to be

@company = Company.find_or_create_by_name(name)

in Rails 4 is now

@company = Company.find_or_create_by(name: name)

Another way to do this in Rails 4 would be:

@company = Company.where(name: name).first_or_create
