Hello. I see that it is almost possible for sequel to work with multiple
databases. But I've found a design issue.
require "sequel"
def db_scope(db)
unless db.table_exists?(:authors)
db.create_table :authors do
primary_key :id
end
end
unless db.table_exists?(:books)
db.create_table :books do
primary_key :id
end
end
unless db.table_exists?(:authors_books)
db.create_table :authors_books do
primary_key :id
foreign_key :author_id, :authors
foreign_key :book_id, :books
end
end
authors = Class.new Sequel::Model(db[:authors]) do
many_to_many :books
end
books = Class.new Sequel::Model(db[:books]) do
many_to_many :authors
end
authors.create.books
end
db_scope Sequel.connect("postgres://user@localhost")
We can see the following error:
uninitialized constant Book (this happened when attempting to find the
associated class for
#<Sequel::Model::Associations::ManyToManyAssociationReflection
#<Class:0x00005654163d1fb0>.many_to_many :books>)
Sequel wants "::Book" class. But it is not possible to provide such class
in global scope if we want to maintain multiple Books classes for multiple
db client instances. Book could be defined in db scope, not in global
scope. How to solve such question? Should I create a github issue?
