Set value in controller using nested resource

- by vectran

I have two models, product and order. Product - cost - id Order - cost - product_id Each time someone places an order, it captures the product_id through a radio button value in the "new order" form. In the controller when creating the new order it needs to set order.cost to order.product.cost. Logically I thought the code should be something like this: def create ... @order.cost == @order.product.cost ... end However I can't seem to make it work at all, hence me asking the question here. Any help is answering (or naming) the question would be greatly appreciated.

Ruby library for manipulating existing PDF

- by simonwh

I'm searching for a library to edit already existing PDF's and add a watermark to each page, for example. Could also be blank every other page etc. There seem to be a few PDF libraries out there, but only very few of them can edit existing PDF's and I'm a bit lost on which way to go. Any recommendations? Thank you.

AssociationTypeMismatch with Expected Type on Nested Model Forms

- by Craig Walker

I'm getting this exception when doing a nested model form: ActiveRecord::AssociationTypeMismatch in RecipesController#update Ingredient(#35624480) expected, got Ingredient(#34767560) The models involved are Recipe and Ingredient. Recipe has_many and accepts_nested_attributes_for :ingredients, which belongs_to :recipe. I get this exception when attempting to _destroy (=1) one of the preexisting Ingredients on a nested Ingredient form for the Recipe Edit/Update. This makes very little sense, mostly because the association types are as expected (by the exception's own admission). What makes even less sense is that it works just fine in a functional test. Any ideas what might be causing this, or what I should be looking for?

Active Record two belongs_to calls to the same model

- by ethyreal

In linking a sports event to two teams, at first this seemed to make since: events - id:integer - integer:home_team_id - integer:away_team_id teams - integer:id - string:name However I am troubled by how I would link that up in the active record model: class Event belongs_to :home_team, :class_name => 'Team', :foreign_key => "home_team_id" belongs_to :away_team, :class_name => 'Team', :foreign_key => "away_team_id" end Is that the best solution? In an answer to a similar question I was pointed to single table inheritance, and then later found polymorphic associations. Neither of which seemed to fit this association. Perhaps I am looking at this wrong, but I see no need to subclass a team into home and away teams since the distinction is only in where the game is played. I thought also about a has_many through association but that seems two much as I will only ever need two teams, but those two teams don't belong to any one event. event_teams - integer:event_id - integer:team_id - boolean:is_home Is there a cleaner more semantic way for making these associations in active record? Thanks

Clean Up Controller, Update Item Quantity within Cart

- by Karl Entwistle

Hi guys I was wondering if anyone could help me out, I need to clean up this controller as the resulting code to simply update an items quantity if it already exists seems way too complex. class LineItemsController < ApplicationController def create @product = Product.find(params[:product_id]) if LineItem.exists?(:cart_id => current_cart.id) item = LineItem.find(:first, :conditions => [ "cart_id = #{@current_cart.id}"]) LineItem.update(item.id, :quantity => item.quantity + 1) else @line_item = LineItem.create!(:cart => current_cart, :product => @product, :quantity => 1, :unit_price => @product.price) flash[:notice] = "Added #{@product.name} to cart." end redirect_to root_url end end ` As always any help is much appreciated, the code should be fairly self explanatory, thanks :) PS posted it here as well as it looks a bit funny on here http://pastie.org/994059

Two models, one STI and a Validation

- by keruilin

Let's say I have two tables -- Products and Orders. For the sake of simplicity assume that only one product can be purchased at a time so there is no join table like order_items. So the relationship is that Product has many orders, and Order belongs to product. Therefore, product_id is a fk in the Order table. The product table is STI -- with the subclasses being A, B, C. When the user orders subclass Product C, two special validations must be checked on the Order model fields order_details and order_status. These two fields can be nil for all other Product subclasses (ie A and B). In other words, no validation needs to run for these two fields when a user purchases A and B. My question is: How do I write validations (perhaps custom?) in the Order model so that the Order model knows to only run the validations for the two fields -- order_details and order_status -- when Product subclass C is being saved to the orders table?

Problem with Railscast #197 - Nested Model Form Part 2

- by sscirrus

I'm trying to implement Ryan's Railscast #197 in a system with Questions, Answers, and (multiple choice) Options. http://railscasts.com/episodes/197-nested-model-form-part-2. I have successfully implemented the nesting among these forms/partials. The simpler 'check box' way to delete records works properly. The problem occurs when I try to add/delete records. I have copied the code exactly as it appears in his Railscast: #new.html.erb <%= javascript_include_tag :defaults, :cache => true %> <% f.fields_for :in_options do |builder| %> <%= render "option_fields", :f => builder %> <% end %> #_option_fields.html.erb partial <%= f.hidden_field :_destroy %> <%= link_to_function "remove", "remove_fields(this)" %> #application_helper.rb (exact same as #197) def link_to_remove_fields(name, f) f.hidden_field(:_destroy) + link_to_function(name, "remove_fields(this)") end def link_to_add_fields(name, f, association) new_object = f.object.class.reflect_on_association(association).klass.new fields = f.fields_for(association, new_object, :child_index => "new_#{association}") do |builder| render(association.to_s.singularize + "_fields", :f => builder) end link_to_function(name, h("add_fields(this, \"#{association}\", \"#{escape_javascript(fields)}\")")) end #application.js (exact same as #197. I have an Event.addbehavior below this code.) function remove_fields(link) { $(link).previous("input[type=hidden]").value = "1"; $(link).up(".fields").hide(); } function add_fields(link, association, content) { var new_id = new Date().getTime(); var regexp = new RegExp("new_" + association, "g") $(link).up().insert({ before: content.replace(regexp, new_id) }); } 2 problems: When I click on the 'remove' link it doesn't remove - it just shifts the page up or down. When I include link_to_add_fields "Add Answer", f, :answers, I get undefined method `klass' for nil:NilClass. Thanks everyone.

validates_uniqueness_of with HABTM relationship

- by jeffshantz

I've got a HABTM relationship between two models: Publication and Author. I want to ensure that one cannot create a publication with the same title, year, and author list. However, if I try something like this: class Publication < ActiveRecord::Base validates_uniqueness_of :title, :scope => [:year, :authors] end This obviously won't work since there is no authors column. Can this be done with validates_uniqueness_of, or do I need a custom validator? Thank you.

Simple multilingual CMS?

- by Christoffer

Hi, I have been searching for a while now for a dead simple CMS with multi-language support. The ideal candidate is very lean and offers the possibility to set up different languages for different domains. It's OK if the language support is provided by a plugin/extension. For example I want example.com to point to English and example.fr should be French. With different URI-mappings for SEO. It can be developed in either of PHP, Ruby or Python and has to be open source. Any tips? Thank you EDIT / MORE DETAILS What I want is a CMS that is as simple to use and grasp for a client as Radiant is, but with tabs on each resource that can translate articles to different languages. Languages have to be able to use multiple domains, one for each language. I want to easily use the same article for more than one language as well as have articles (e.g. blog posts or news stories) that are only connected to one language. The CMS should be very light in core functionality (like Radiant, unlike Drupal/Joomla) but be easily extendable with plugins.

Devise routes to only use custom sign in page

- by eblume

I am trying to learn Devise and seem to have hit a problem that is nearly the same as many, many questions here on SO but just slightly different enough that I am not getting much traction following those questions' threads. I have a very simple application. Users can sign in and sign out (and also the devise 'forgot password' stuff is enabled - I am not concerned about it at this time) and that is it. They can't register, they can't edit their profile other than to change their password, they can't do anything except sign in and sign out. (Account creation will, for now, be handled manually at the command line.) I would vastly prefer that the only page that users can log in from was "/" (root_path). I already have it working where you can log in from "/", and that is great. The problem I am having is that if you type in your user/password combination incorrectly from the root_path login page, it automatically sends you to the Devise sign-in page to continue trying to sign in. How can I make Devise redirect to root_path on sign-in failure? Here are my routes - they are probably not optimal or correctly configured and I would appreciate pointers on fixing them: root to: "core_pages#splash" devise_for :users, skip: [:sessions] as :user do # get 'signin' => 'devise/sessions#new', as: :new_user_session post 'signin' => 'devise/sessions#create', as: :user_session delete 'signout' => 'devise/sessions#destroy', as: :destroy_user_session, via: Devise.mappings[:user].sign_out_via end match '/home' => 'core_pages#home' Note the commented-out 'get signin' line. The system works without this line but, surprisingly (to me), "GET /signin" results in a HTTP 400 (OK) response and renders the Devise login template. I would prefer it return some sort of 'invalid request' or just silently redirect the user to root_path. Running rake routes on these routes gives: root / core_pages#splash user_password POST /users/password(.:format) devise/passwords#create new_user_password GET /users/password/new(.:format) devise/passwords#new edit_user_password GET /users/password/edit(.:format) devise/passwords#edit PUT /users/password(.:format) devise/passwords#update user_session POST /signin(.:format) devise/sessions#create destroy_user_session DELETE /signout(.:format) devise/sessions#destroy home /home(.:format) core_pages#home Thanks!

How active record is automatically setting up the autoincremental value of ID?

- by piemesons

Here this is what we are doing:-- an_order = Order.new an_order.name = "Dave Thomas" an_order.email = "[email protected]" an_order.address = "123 Main St" an_order.pay_type = "check" an_order.save Now it will insert a new row in orders table right. I m having a ID column in that table. Now suppose after inserting this record the value of the ID corresponding to this record is 100. Now how this 100 value came to know? Does the previous value of ID ie 99 (Suppose) is stored somewhere in some variable/file in the ORM layer or before inserting this value a query was fired to know about the last inserted value or database is itself doing that or anything else???

Modifying records in my migration throws an authlogic error

- by nfm

I'm adding some columns to one of my database tables, and then populating those columns: def self.up add_column :contacts, :business_id, :integer add_column :contacts, :business_type, :string Contact.reset_column_information Contact.all.each do |contact| contact.update_attributes(:business_id => contact.client_id, :business_type => 'Client') end remove_column :contacts, :client_id end The line contact.update_attributes is causing the following Authlogic error: You must activate the Authlogic::Session::Base.controller with a controller object before creating objects I have no idea what is going on here - I'm not using a controller method to modify each row in the table. Nor am I creating new objects. The error doesn't occur if the contacts table is empty. I've had a google and it seems like this error can occur when you run your controller tests, and is fixed by adding before_filter :activate_authlogic to them, but this doesn't seem relevant in my case. Any ideas? I'm stumped.

Rendering a variable with erb.

- by TZer0

I've got the following problem: I have rhtml (html minced together with ruby inside <% % and <%= % tags) stored in a database which I want to render. The information is acquired through a query. I need to be able to evaluate the information I get from the database as though as it was normal content inside the .erb-file. What I currently have: <% @mymods.each do |mod| %> <%= render_text(mod["html"])%> <% end %> Where mod["html"] is the variable containing the rhtml-code and @mymods an array of objects from the query. I have currently no idea what function I should use (render_text does, of course, not work). Help is greatly appreciated. /TZer0
