[Rails] Re: Wrong number of arguments (0 for 1) in callback method
Hi Matt, Actually I am trying to connect to already existing DB where mentioned table is readily available. I just need to read it all the time or occasionally write it but I do not create it from my app. The primary key of the table is varchar. I can do nothing about that and if i do not declare it into my model, it will assume a primary key 'id' in the table. Is there any better way here? PS: i cannot see your posting on ruby-forum. Will it take LOTS of time for that to appear on the site or something else? -Kalpesh On Sat, Nov 14, 2009 at 10:54 PM, Matt Jones al2o...@gmail.com wrote: Somewhat unrelated, but if you're creating a new, simple Rails app, why are you tangling with set_table_name and a noninteger primary key?

Hi Kalpesh1 Patel So isn't there any way I can pass some value from controller to model? You can define cname as n attr_writer in model and can set its value from controller like @simple.cname = 'namehere' Sijo -- Posted via http://www.ruby-forum.com/. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.

For example, authentication, logging or similar stuff I will perform just before 'save'(this might raise another question, is this right approach? but this can be a separate discussion). I thought of passing the value in the callback method itself but now I am able to do it through attr_accessor.
