undefined method 'each` for @<Plan:0xb75eb818>

I am having a problem seaching my Plan object with Plan.find() using an array object that appears to be setting itself up incorrectly. Here is what I am seeing.

NoMethodError in Generate reportsController#advanced_plan_summary

undefined method `each' for #<Plan:0xb7605a24>

/usr/local/lib/ruby/gems/1.8/gems/activerecord-1.15.3/lib/ active_record/base.rb:1860:in `method_missing' app/controllers/generate_reports_controller.rb:419:in `advanced_plan_summary'

Request

Parameters: {"plans"=>"3/29"}

How is Ruby setting up my arrays as a string like this instead. Has anyone seen this before?

I am using Rails 1.2.3 Ruby 1.8.6 gems 0.94

I found the problem. You were correct. I kept thinking Ruby was misformating the parameter straing. Thinking I should see and array in Parameters: {"plans"=>"3/29"}. This was correct.

@plans = Plan.find(params[:plans]) My problem was with this code

for plan in @plans .... end

I had to change it to for plan in @plans.to_a ... end

and it worked. Thanks
