Hello i got this:
<%Payment.find_all.each do |p|%>
<li><a
href="#"><%=p.member.name%>-<%=p.payer_id%></a></li>
<%end%>
it throw :
You have a nil object when you didn''t expect it!
The error occurred while evaluating nil.name
but if i do the same in the script/console it just do it fine, but at
the end of all it throw the same thing:
i got:
class Payment < ActiveRecord::Base
set_table_name :payments
belongs_to :member, :foreign_key=>:userid
end
class Member < ActiveRecord::Base
set_primary_key :userid
has_many :payment, :foreign_key=>:userid
end

So for that payment object, userid would be nil, which means you can''t dereference it to obtain a user. A few comments about your code: 1) don''t use find_all, it''s been deprecated. Use Payment.find(:all) instead 2) put your finders in your controller, that''s where they belong. Use @payments = Payment.find(:all) and then in your view do something like <% @payments.each do |payment| %>> but if i do the same in the script/console it just do it fine, but at > the end of all it throw the same thing: > > i got: > > class Payment < ActiveRecord::Base > set_table_name :payments > belongs_to :member, :foreign_key=>:userid > endyou don''t need to use set_table_name here, the associated table name will by default be called ''payments'' the rails convention for foreign key naming is to use classname_id. So you should get into the habit of using user_id to reference a User object. In this case it doesn''t really matter, but you might as well follow convention.
