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 :p
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”) %\>

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