salami-art / _form.rb

Created November 20, 2013 13:53

Want to create a new author using "Author" field in the form in books/new, if it doesn't exist yet. The code provided in _form is not working. Routes autor/new, author/create are available.

	<%= form_for([@author, @book]) do \|f\| %>
	<% if @book.errors.any? %>
	<div id="error_explanation">
	<h2><%= pluralize(@book.errors.count, "error") %> prohibited this book from being saved:</h2>

	<ul>
	<% @book.errors.full_messages.each do \|msg\| %>
	<li><%= msg %></li>
	<% end %>
	</ul>

salami-art / author.rb

Created November 20, 2013 20:09

I can create a new book, as desired, in pair with its author by running: > book = Book.create(:title => "title", :author_attributes => {:name => "name"}, :text => "text") However, every attempt to post via http results in error: "Author can't be blank" I've already tried with: [...] <%= fields_for :author , @book.author do |ff| %> <li>Author<br>…

	class Author < ActiveRecord::Base
	validates :name, :presence => true
	has_many :books, :inverse_of => :authors
	end

salami-art / controller

Created November 20, 2013 23:45

'books' route called with redirect_to assigns variable as expected, Action :index (same page) called with render doesn't.

	class BooksController < ApplicationController

	def index
	@books = Book.all # # this variable doesn't get loaded with " render "


	respond_to do \|format\|
	format.html
	format.yaml { render text:@books.to_yaml }
	format.json { render text:@books.to_json }
