Rails: my ruby code breaks heroku

Ruby code in my view crashes my rails app on heroku. Meanwhile it works in development. I'm using HAML.

    = @sold
    - @sold.each do |x|
      %p lorem

It breaks on the second line - @sold.each do |x| regardless if @sold is equal to nil or if it has a value. Do you guys have any clue as to why?

controller: 

  def activity
    @user = current_user 
    @selling = @user.products.where( "quantity != ?", 0 )
    @sold = @user.products.where( "quantity == ?", 0 )
  end

EDIT : Heroku logs says 

"HINT:  No operator matches the given name and argument type(s). You might need to add explicit type casts.

Try changing this line:

@sold = @user.products.where("quantity == ?", 0)

To this:

@sold = @user.products.where(quantity: 0)

I think the problem is because you're trying to use the double equals as a matcher in PostgreSQL, but it does not support that. You should use = if you want to check for equality there.
