For example, let's define a user_id column on the posts table that references the id column on a users table: Since this syntax is rather verbose, Laravel provides additional, terser methods that use conventions to provide a better developer experience. bigInteger Here are some examples: If you pass an array of columns into a method that drops indexes, the conventional index name will be generated based on the table name, columns, and index type: Laravel also provides support for creating foreign key constraints, which are used to force referential integrity at the database level.
