I am fairly new to rails and am working on a system that is currently  
being developed with Rails 1.1.6.  
I am trying to do a save on a object that is giving me an undefined  
method message

Here is what I have.

Ruby 1.8.4  
Rails 1.1.6

reorder is an iteger in the PlanProcedures table.  
I am running mysql 5.

@plan\_procedure = PlanProcedure.find(params[:id])

@plan\_procedure.reorder = 0  
@plan\_procedure.save

undefined method `reorder=’ for #PlanProcedure::Version:0xb7a3c098

Unless there’s some problem with the versioning plugin,  
try switching to the C MySQL Ruby bindings if you’re using the  
pure Ruby version.

Here is what I have found… If I do a migration and add a field to my  
PlanProcedure \< ActiveRecord::Base with 1.1.6  
any .saves or updates to this class appear to fail out with this  
undefined method `added column name=’ for #\<PlanProcedure…  
Does anyone know if this is something resolved in the 1.2.3 update???

After adding the column in the migration you have to call  
PlanProcedure.reset\_column\_information before you can do any  
saves or updates within the migration.

I tried to add the C bindings and it did not appear to resolve the  
problem. I am beginning to think it may be an issue with 1.1.6.  
Perhaps resolved within 1.2.3.  
I am looking to move this system to 1.2.3 which is another issue  
altogether. When I am running a create on my PlanProcedure class it  
also gives me this error. When I remove the extra column ‘reorder’ it  
appears to be OK as far as creating?
