DangerousAttributeError

I upgraded to rails 2.0.2
so i get this error
ActiveRecord::DangerousAttributeError in Asset#show

this is in the view
<div class="price"><%=h shekels_to_dollars(@asset.price_shekel,
options = {:precision => 0}) %></div>

when i delete this line every thing is ok

This is in application helper
#Converts a shekels amount to a dollar amount and outputs as a
currency.
  def shekels_to_dollars (amount_in_shekels, options = {})
    @dollar = Rate.find(1).rate
    if amount_in_shekels
      amount_in_dollars = amount_in_shekels.to_f / @dollar.to_f
    return number_to_currency(amount_in_dollars, options)
    end
  end

this is the db table
class CreateRates < ActiveRecord::Migration
  def self.up
    create_table :rates do |t|
    t.column :name, :string
    t.column :rate, :float, :default => 0
    t.column :update, :date
    t.column :updated_at, :datetime
    end
  end

  def self.down
    drop_table :rates
  end
end

Please help

Raised when attribute has a name reserved by Active Record (when
attribute has name of one of Active Record instance methods).

In your case that's most likely the "update" attribute, since it would
overwrite ActiveRecords update method

Thanks Thorsten

Is renaming the attribute at the database level the only option to
work around this issue?

At work we have similar situation where many other applications/
platforms make use of the same database table so changing the schema
incurs more risk that simply ensuring that the Rails App can play
along so when it's not possible to change the column name on a table
how do you fix this issue?

For instance how do you map an accessor from a column in the db that
clashes with an existing method provided by ActiveRecord::Base?

Hi Robert,
