Hello,
I have 2 legacy tables I want to join:
DB TABLES Transaction_Details Accounts
I want to join Transaction_Detail.Account with Accounts.Account.
I also want to be able to select Transaction_Details based on a field in the Accounts table. Is that possible? I'm thinking it should be.
I'd prefer to do it with Active Record, as opposed to find_by_sql.
I currently have:
MODELS - transaction_detail.rb - class Transaction_Detail < ActiveRecord::Base set_table_name "Transaction_Details"
has_one :account end
- account.rb -
class Account < ActiveRecord::Base set_table_name "Accounts"
has_many :transaction_details end
CONTROLLER TransactionDetail.find(:all) ... not sure what to do about the :conditions here
Two things. First you can override the default primary key for a model with self.primary_key in your model such as:
class Account < ActiveRecord::Base set_table_name "Accounts" set_primary_key "account" # or # self.primary_key = "account"
Second you can override the default column used for a join with :foreign_key such as:
class Account < ActiveRecord::Base set_table_name "Accounts" set_primary_key "account" # or # self.primary_key = "account"
has_many :transaction_details, :foreign_key => "account"
