Destroy ActiveRecord gives us the CRUD methods (Create, Read, Update, and Delete) for free—this alone is a great benefit. But ActiveRecord does a lot more. In the next section we’ll see how it helps us express the relationships between tables. 36 O BJECT -R ELATIONAL M APPERS Cultivating Relationships with Flowers Now that we have so many flowers, we should try to make some wonderful bouquets out of them. We’ll need another table to represent them. Because we know that we will access it with ActiveRecord, we’ll call it bouquets.
Print_report This produces the following values: rose: 1000 in stock. violet: 2000 in stock. sunflower: 500 in stock. 87. 44 O BJECT -R ELATIONAL M APPERS Where to Put Constraints? Putting constraints on columns and on the relationships between tables is a two-edged sword. On the one hand, you have constraints that apply globally and can be checked only by the database system itself. It does not make sense—and often is impossible—to implement primary keys, foreign keys, or unique constraints in your application.
We want to implement the relationship between the bouquets table and the flowers table. By default, ActiveRecord searches for a table that is named after the tables to be joined. Concatenate the table names in lexical order and separate them by an underscore, and you have the name of your join table. In addition, the join columns follow a naming scheme, too. You have to append _id; to the class name in lowercase letters (camel case is turned into underscores). 2: Join Table for Bouquets and Flowers class Flower < ActiveRecord::Base has_and_belongs_to_many :bouquets end Many-to-many relationships are symmetrical, so we have to use the has_and_belongs_to_many( ) macro in both the Flower and Bouquet classes.
