Question

I’m some what new with ruby on rails, so I’m attempting to debug this error that I’m getting but, from my understanding, is working on the prod code.

The error:

NoMethodError in JoinController#index
undefined method `join_template' for nil:NilClass
/app/controllers/join_controller.rb:5:in `index'

Okay, so line 5 in index is:

elsif current_brand.join_template == 'tms'

So clearly current_brand is nil. The controller is a child class of AppController, so checking that out I see that current_brand is a method:

  def current_brand
    return @current_brand if defined?(@current_brand)
    url_array = request.env['HTTP_HOST'].split('.').reverse
    url = url_array[1] << "." << url_array[0]
    @current_brand = Brand.find(:first, :conditions => ["url LIKE ?", "%" << url << "%"])
  end

It seems that @current_brand is always returned, yet it’s continuing to be Nil. What could the problem be?

Answer 1

It may be your query is not returning anything. You can use a debugger, but it’s pretty easy to just output @current_brand and see what it evaluates to.

logger.debug(@current_brand)
