I have a question about has_many associations :
Here is a sample of my db/models :
documentid : int
name : text
class Document < ActiveRecord::Base
has_many :document_pages
has_many :pages, through: :document_pages
end
pageid : int
content : text
class Page < ActiveRecord::Base
has_many :document_pages
has_many :documents, through: :document_pages
end
document_pagesdocument_id : int
page_id : int
page_number : int
class Page < ActiveRecord::Base
belongs_to :pages
belongs_to :documents
end
I am creating the page and the document and I link the two this way :
page = Page.create(:content => 'lorem')
document = Document.where(:id => id).first_or_initialize.tap do |document|
document.pages << page unless document.pages.include?(page)
end
And in the line document.pages << page I want to provide the field page_number of the table document_pages.
Do you know how to do it ?
Do it differently :
page = Page.create(:content => 'lorem')
document = Document.where(:id => id).first_or_initialize. do |document|
document.document_pages.build(page: page, page_number: 1 ) unless document.pages.include?(page)
document.save!
end
