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:

&nbsp;&nbsp;&nbsp;&nbsp;create\_table :supermarket do |t| &nbsp;&nbsp;&nbsp;&nbsp;t.integer :groceries\_id &nbsp;&nbsp;&nbsp;&nbsp;t.decimal :price, :precision =\> 8, :scale =\> 2 &nbsp;&nbsp;&nbsp;&nbsp;t.integer 😛&nbsp;&nbsp;&nbsp;&nbsp;t.decimal :numindeal, :precision =\> 8, :scale =\> 2 &nbsp;&nbsp;&nbsp;&nbsp;t.decimal :promprice, :precision =\> 8, :scale =\> 2 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;t.timestamps &nbsp;&nbsp;&nbsp;&nbsp;end

Table

id |groceries\_id |price|p|numindeal|promprice| 1 |1| |3.00|1|3.00 ||3.00 |

Helper.rb

&nbsp;&nbsp;def pricecheck(groceries,supermarket) &nbsp;&nbsp;&nbsp;&nbsp;z = groceries.send(supermarket)

z.groceries\_id z.price z.numindeal z.promprice {all these work} &nbsp;&nbsp;z.p {this gives "wrong number of arguments (0 for 1)"} &nbsp;&nbsp;end

view code:

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

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