Seriously stumped cannot call attribute out

Hi, i am having problems displaying a simple attribute. what is weird is that all the other attributes are can be called but not .p . I have been racking my brain on why but I just don't get it. it doesn't make sense i can call nearly every attribute except this one

DB creation code:

    create_table :supermarket do |t|     t.integer :groceries_id     t.decimal :price, :precision => 8, :scale => 2     t.integer :stuck_out_tongue:     t.decimal :numindeal, :precision => 8, :scale => 2     t.decimal :promprice, :precision => 8, :scale => 2       t.timestamps     end

Table

id |groceries_id |price|p|numindeal|promprice| 1 |1| |3.00|1|3.00 ||3.00 |

Helper.rb

  def pricecheck(groceries,supermarket)     z = groceries.send(supermarket)

z.groceries_id z.price z.numindeal z.promprice {all these work}   z.p {this gives "wrong number of arguments (0 for 1)"}   end

view code:

<%= pricecheck(groceries,"supermarket") %>

this is what it says in console

Groceries.find(1).supermarket.p ArgumentError: wrong number of arguments (0 for 1)

        from /usr/lib/ruby/gems/1.8/gems/activerecord-2.1.0/lib/ active_record/associations/association_proxy.rb:177:in `p'         from /usr/lib/ruby/gems/1.8/gems/activerecord-2.1.0/lib/ active_record/associations/association_proxy.rb:177:in `send'         from /usr/lib/ruby/gems/1.8/gems/activerecord-2.1.0/lib/ active_record/associations/association_proxy.rb:177:in `method_missing'         from (irb):30

Nevermind found out. You cannot use p for a column name
