So I'm trying to set a name attribute of organizations and create a new organization or choose from a previously existing organization from the same form.
I've tried to follow Ryan Bates' railscast on the topic here: http://railscasts.com/episodes/57-create-model-through-text-field
I have also tried numerous solutions from stack. However, I can't quite seem to get it to run (that and I have a validation that does not recognize the virtual attribute I'm using)
so my organizations model:
class Organization < ActiveRecord::Base
has_many :materials
has_many :users
has_and_belongs_to_many :causes
has_and_belongs_to_many :schools, :join_table => 'organizations_schools'
####The following line has been edited ####
attr_accessible :name, :unlogged_books_num, :id, :new_organization_name
attr_accessor :new_organization_name
before_validation :create_org_from_name
validates_presence_of :name
def self.assign_school_to_organization(org, school)
orgschool = OrganizationsSchool.create(:organization_id=> org.id, :school_id=> school[0])
end
def create_org_from_name
create_organization(:name=>new_organization_name) unless new_organization_name.blank?
end
end
I have also tried the create_org_from_name as the following:
def create_org_from_name
self.name = new_organization_name
end
And this does not change the name to the organization name before validating or saving the instance.
I have also tried to change the before_save to before_validation, and that has not worked
My controller for organization (I also tried to change this in create)
def create
respond_to do |format|
#organization = Organization.new(params[:organization])
#organization.name = #organization.new_organization_name unless #organization.new_organization_name.blank?
if #organization.save
#school = params[:school]
Organization.assign_school_to_organization(#organization, #school)
format.html { redirect_to #organization, notice: 'Organization was successfully created.' }
format.json { render json: #organization, status: :created, location: #organization }
else
format.html { render action: "new" }
format.json { render json: #organization.errors, status: :unprocessable_entity }
end
end
end
And finally, I have what my form is doing currently:
<%= form_for(#organization) do |f| %>
<% if #organization.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(#organization.errors.count, "error") %> prohibited this organization from being saved:</h2>
<ul>
<% #organization.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<% #schools = School.all %>
<% #organizations = Organization.all %>
<div class="field">
<%= f.label 'Organization Name' %><br />
<%= f.collection_select(:name, #organizations, :name, :name, :prompt=>"Existing Organization") %>
Or Create New
<%= f.text_field :new_organization_name %>
</div>
<div class="field">
<%= f.label :unlogged_books_num %><br />
<%= f.number_field :unlogged_books_num %>
</div>
<div class="field">
<%= f.label 'School' %><br />
<% school_id = nil %>
<%= collection_select(:school, school_id, #schools, :id, :name) %>
</div>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
==================================EDIT============================================
So currently, when I try to make an organization with something only written in the virtual text field, My log tells me the following:
Processing by OrganizationsController#create as HTML
Parameters: {"utf8"=>"✓", "authenticity_token"=>"igoefz8Rwm/RHrHLTXQnG48ygTGLydZrzP4gEJOPbF0=", "organization"=> {"name"=>"", "new_organization_name"=>"Virtual Organization", "unlogged_books_num"=>""}, "school"=>["1"], "commit"=>"Create Organization"}
Rendered organizations/_form.html.erb (7.1ms)
Rendered organizations/new.html.erb within layouts/application (8.0ms)
Completed 200 OK in 17ms (Views: 12.2ms | ActiveRecord: 1.0ms)
================================EDIT 2============================================
So this is what I get from the rails console if I try to create a new organization running this command: Organization.create(:new_organization_name=>"Virtual Organization", :unlogged_books_num=>"3")
irb(main):001:0> Organization.create(:new_organization_name=>"Virtual Organization", :unlogged_books_num=>"3")
(0.1ms) BEGIN
(0.1ms) ROLLBACK
=> #<Organization id: nil, name: nil, unlogged_books_num: 3, created_at: nil, updated_at: nil>
If the function of create_org_from_name is self.name = new_organization_name, then the result of the same command from the console is blank:
irb(main):002:1> Organization.create(:new_organization_name=>"Virtual Organization", :unlogged_books_num=>"3")
irb(main):003:1>
You need:
before_validation :create_org_from_name
and
def create_org_from_name
self.name = new_organization_name if not new_organization_name.blank?
end
You don't want to do a create in your before_validation method.
I have watched the railscasts on Pagination with AJAX. I am trying to duplicate his method using a nested model. I seem to be confused because i don't have a view for the child model or a fully integrated controller.
Assume the Product has_many Comments. How can I do the same pagination using will_paginate on comments within a product view?
UPDATE:
Here is most of my attempt (my attempt actually uses kaminari but it's basically the same as will_pagenate):
view/products/comments/_index.html.erb:
<div id="comments">
<% comments.each do |comment| %>
<%= f.fields_for :comments, comments do |comment_builder| %>
<%= render 'products/comments/field', f: comment_builder %>
<% end %>
<% end %>
<%= paginate comments %>
</div>
view/products/comments/_field.html.erb:
<fieldset>
<%= f.hidden_field :_id, :value => f.object._id %>
<%= f.hidden_field :_destroy %>
<%= f.object.text %>
<%= link_to "remove", '#', class: "remove_field" %>
</fieldset>
view/products/comments/_index.js.erb:
$("#comments").html("j render("products/comments/index")) %>");
assets/javascripts/product.js
$('.pagination a').live
click: ->
$(".pagination").html("Page is loading...")
$.getScript(this.href)
false
controllers/comments_controller.rb
class CommentsController < ApplicationController
before_filter :get_product
def index
#comments = #product.comments.desc(:created_at).page(params[:page]).per(10)
respond_to do |format|
format.html # index.html.erb
format.json { render json: #comments }
end
end
private
def get_product
#product = Product.find(params[:product_id]) if params[:product_id]
redirect_to root_path unless defined?(#product)
end
end
views/products/show.html.erb (an excerpt)
<%= render "products/comments/index", f: f, comments: #comments%>
controllers/products_controller.rb
def show
#product = Product.find(params[:id])
#comments = #product.comments.desc(:created_at).page(params[:page]).per(1)
respond_to do |format|
format.html # show.html.erb
format.json { render json: #product }
end
end
view/products/comments/_index.js.erb never gets called. Also is there a more rails-like way of doing this?
I'm know this is a newbie question just not sure what I'm missing and decided to post hear after my usual search through Google. I'm trying to post content to the database from a form in the footer of the application (for a newsletter) the view is therefore repeated throughout the application. Right now when I submit the form a new object is created in the database but all the fields are "NULL". It seems I need to put the #newsletter variable somewhere, I'm just not sure where.
Partial I'm Rendering in the View
<%= form_tag({:controller => "newsletters", :action => "create"}, :method => "post", :id => "footer_email_form") do %>
<%= text_field_tag :first_name, '', id: "footer_email_firstname" %>
<%= text_field_tag :last_name, '', id: 'footer_email_lastname' %>
<%= text_field_tag :email, '', id: 'footer_email_address' %>
<%= submit_tag "Submit", :name => nil, id: 'footer_email_submit', class: "btn btn-primary" %>
<% end %>
Controller (Create Action)
class NewslettersController < ApplicationController
def create
#newsletter = Newsletter.new(params[:newsletter])
if #newsletter.save
format.html { redirect_to 'pages#home', notice: 'Thank You for signing up for our newsletter' }
format.json { render json: #newsletter, status: :created, location: #newsletter }
else
format.json { render json: #newsletter.errors, status: :unprocessable_entity }
end
end
end
Routes
resources :newsletters, :only => [:create, :destroy]
Use something like this:
<%= form_for Newsletter.new do |f| %>
<%= f.text_field :first_name %>
<%= f.text_field :last_name %>
<%= f.text_field :email %>
<%= f.submit_tag "Submit", class: "btn btn-primary" %>
<% end %>
The way your original form works the params are submitted like this:
params = {
:first_name => 'A',
:last_name => 'B',
:email => 'C',
# and so on...
}
Now if you do #newsletter = Newsletter.new(params[:newsletter]) nothing will happen, because params[:newsletter] is nil and therefore all your attributes are going to be nil (and show up as NULL in the DB).
You should always have an eye on the development log. It's going to help you debug such errors.
I'm in rails 3.2.2
I'm trying to create a new perfil inside a persons_controller
Models symplify:
class Person < ActiveRecord::Base
belongs_to :perfil, :foreign_key=>'perfil_id'
class Perfil < ActiveRecord::Base
has_one :person
I created ad_perfil inside persons_controller
def ad_perfil
#person = Person.find(params[:id])
#perfil = Perfil.new
end
and I supused 2 ways:
1) using f.submit
ad_perfil.html.erb:
<%= #person.nombre %>
<%= form_for(#perfil) do |f| %>
<div class="field">
<%= f.label :nombre %><br />
<%= f.text_field :nombre %>
</div>
<%= f.submit %>
<% end %>
this redirect me to create to perfils_controller and there I can't get #persona:
def create
#perfil = Perfil.new(params[:perfil])
#person = Person.find(params[:id])
respond_to do |format|
if #perfil.save
format.html { redirect_to #perfil, notice: 'Perfil was successfully created.' }
format.json { render json: #perfil, status: :created, location: #perfil }
#person.perfil_id = #perfil.id
#person.save
2) I created a new def in persons_controller:
def new_perf
#perfil = Perfil.new(params[:perfil])
#person = Person.find(params[:id])
if #perfil.save
#person.perfil = #perfil
#person.update_attributes(params[:person])
redirect_to #person
end
end
and I tryed change f.submit for:
<td><%= link_to 'New Perfil', :action => "new_perf", :id=> #person.id %></td>
and it created a new perfil without any field and of course don save perfil.id inside #person.perfil_id.
Is possible that I'm trying? Is there any other methods? I guess that will be more easy puting perfil.person_id instead person.perfil_id but I want access to person.perfil later.
I hope you understand me, and maybe I don't understand "submit" very well. any suggestions? thanks!
I'm relatively new to rails and am trying to pull off my first polymorphic association with comments.
I am running rails 3.2.3
Edit - When I try to post a comment, my log is returning this error:

I have tried out many different solutions offered on SO and elsewhere, including the answer from Jordan below, due, I'm sure, to my own inexperience, but have been unable to resolve the error.
The trace calls out line 13 in the Comments Controller and I commented after that line below to mark the error:

It is probably something obvious that someone with more experience can resolve. Let me know if anything comes to mind. Brian
The problem is that #commentable is nil, which means that CommentsController#find_commentable is returning nil. I think your regular expression is sound, so that means one of two things is happening in find_commentable:
There aren't any keys in params that match your regex.
Your regex is matching but there aren't any records in the resulting table with the id in value.
Debug this as usual by inspecting params and the records in your database to make sure they look like you expect them to look.
The problem is your find_commentable method.
Here are the params passed to your CommentsController#create:
Started POST "/comments" for 127.0.0.1 at 2012-05-20 13:17:38 -0700
Processing by CommentsController#create as HTML
Parameters: {"utf8"=>"✓", "authenticity_token"=>"SOLcF71+WpfNLtpBFpz2qOZVaqcVCHL2AVZWwM2w0C4=", "comment"=>{"text"=>"Test this comment"}, "commit"=>"Create Comment"}
Here is your CommentsController#create:
def create
#commentable = find_commentable
#comment = #commentable.comments.build(params[:comment]) #<<<<LINE 13
def find_commentable
params.each do |name, value|
if name =~ /(.+)_id$/
return $1.classify.constantize.find(value)
end
end
nil
end
As you can see, find_commentable expects a param like xx_id (for example, comments_id) which it uses to search for an appropriate class (in case of comments_id, it will be Comment), otherwise it returns nil. Refer classify and constantize here.
Your params do not contain any such param. So, you always get a nil object.
Your find_commentable needs some rework. I think in case of nested_fields, it should be an expression like
/(.+)_attributes$/
instead of
/(.+)_id$/.
And you need to have
:accepts_nested_attributes_for :commentable
in your Comment model class.
I tried both of the above answers, but the problem continued.
I ended up consulting with a friend who suggested the following solution, which I like because it's more elegant than my original attempt and easier to read (for later, when I or someone else need to return to the code):
def find_commentable
if params[:post_id]
Post.find(params[:post_id])
#elsif params[:other_id]
# Other.find(params[:other_id])
else
# error out?
end
end
The commented out section will refer to other associations once I get them up and running.
