Should I use class method or instance method, and why?

Question

In my Rails app, when creating a business I have a form that has the following field:

   <%= check_box_tag(:default_company) %> 
   <%= label_tag(:defau         


        

Answer 1

A few things: do you have a separate table for DefaultCompany? This seems like it should be a boolean flag on the company table.

Next, is there an association between companies and users? If so, it seems the best way to do it would be

In the user model

def set_default_company(company)
  self.companies.each do |c|
    c.update_attributes(:default => false)
  end
  company.update_attributes(:default => true)
end

Or in the Company model

def set_as_default
  update_attributes(:default_company => true)
end
