Hello Collin Law, Thank you for replying. To make clear why I want to do above things, here are the details. And yes I started with railstutorials.org and I was able to create successful login page etc. But this is the logic part I'm trying to implement. Here is the details. 1. If I generate members model, then members table will be created in the database 2. If I generate recovery model, then recovery "-----------------"---------------------------". 3. And there is *no* association or any type of relation(one to many, has-many, belongs-to) between these two tables. Now is it possible to access data of members table such as member_code, member_status (active or inactive) etc from recovery model? If possible how? 1. I have members model and the table with so many attributes but right now I'm interested in member_code and member_status. 2. I have loan model and the table. Attributes I'm interested in are loan_type (joint loan or personal loan). 3. I have receipts table (Which contains the information of how much of the loan are already cleared by all members). 4. Now this is the special case. This model called recovery, I created it just because I read that business logic should be implemented inside the model and this model will calculate the remaining amount to be paid by each members. *May be members, loan and receipts table have association or relation between them, but in this recovery model all I want to do is just to read data from different tables and process the data and finally store them inside recovery table.* How can I achieve this ? -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
