similar to: Caching of models?

Wow, I can''t believe that after a few weeks of playing around with Rails I got stuck on something that seems like it should be really simple. How do I display a default welcome page for visitors who are not logged in and send logged in users to the appropriate controller. I am using the login_engine and the user_engine. The two methods I have seen looking at sample code are to stick a

Is there any pattern how to use non-english fonts right in rhtml file? Using ą is frustrating. Thanks, Szczepan _______________________________________________ Rails mailing list Rails-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org http://lists.rubyonrails.org/mailman/listinfo/rails

I have two tables like: Table A: id (autoincrement) name Table B id id_of_A desc I want to add a record to table A and based on the id of A, I want to add a record to table B. I don''t think there is any SQL command that support this (at least in MySQL 4.1, so I use LAST_INSERT_ID()). (Is there any other way? or MySQL 5 support any special SQL command?) But I need

Hi, So finally I have also decided to roll my engines on Rails. But I am kind of stuck in a situation. I understand that for every model there is a controller class. This controller class has cirtain set of methods where each method defines cirtain action to be performed. And each of this action renders cirtain UI. [The background] Now let say I have a object "Car". Apart from

Hi, I am just learing Rails and I am going through the Agile Web Development with Rails book. I am receiving: NoMethodError in Store#add_to_cart undefined method `add_product'' for #<StoreController:0x3764d80> RAILS_ROOT: ./script/../config/..

Given this code (which renders rjs), I''m faced with the fixture- driven way of spec-ing or mocking. How the heck to you mock this so the code at line (2) and (4) work right? I''m still struggling with mocks but it seems like this can be done. Forgive the naivety of this question. 1. def change_quantity 2. @line_item = LineItem.find_by_id(params[:id]) 3. unless

Hello everyone! I''m trying to create an after filter for all my actions in all controllers. I put it in application controller (application.rb). class ApplicationController < ActionController::Base after_filter :tidyit def tidyit xxxx # syntax error - intentionally end end I have a Example (example_controller.rb) controller with index action. class

Hello everyone! I''m thinking of the right way to store tmp/ directory of Rails 1.1 project in Subversion. It has cache, session and sockets subdirectories. To me, it looks good to have svn delete tmp/* svn propset svn:ignore "*" tmp So it will ignore all directories and files in tmp/. Even if you create sessions/ and put some files in it, tmp/ content is still ignored. But

I''m doing the depot example in the Agle Web development book. I''m getting this error: "undefined method `product'' for #<BigDecimal:331ce70,''0.21E1'',8(8)> " "Extracted source (around line #9): 8: for item in @items 9: product = item.product 10: -%> 11: <tr> 12: <td><%= item.product%></td>"

I want to modify and update the items in the Depot - "display_cart". Since the cart is in a session, its a little hard to get at the data. I just want to create a way to change quantities, prices and recalculate. Has someone done this, and could you point me to the right direction. Thanks Chas -- Posted via http://www.ruby-forum.com/.

I want to use something similar to the following: @total_price += { product.price <> nil ? product.price : 0.0 } This fails in rails with a "nil can''t be coerced into Float" error. What is the (most) correct way to do this? On a related issue, what is the significance of the value 40 following "cart.rb" in the trace snippet below? The entire class file

Hello everyone! I''m not sure if it''s right place to ask, but what is your experience with google adsense? I plan to implement free web service for community and would like to cover hosting costs. Is adsense worth the hassle? olegf

I''m working my way through the book Agile Web Development with Rails, and I am in the section where the book has me creating a display_cart method and the associated view. When I copied the code from the book into the view, it threw this error. If anyone could give me some hints where I should be looking I''d appreciate it. NoMethodError in Store#display_cart Showing

Hi, I''m reading the "Agile Web Development With Rails" book. So long, everything has worked fine, but now I got this annoying error message that I just can''t understand. The error appears for me around page 87, chapter 8. NoMethodError in Store#display_cart Showing app/views/store/display_cart.rhtml where line #28 raised: undefined method `product''

I have looked at examples for this. I found a similar example in the Agile Web Dev... book but that didn''t help. Here''s what i am trying to do. A Cart has many line items. On the Display Cart page, I want to provide the user the option to update quantities. Here''s the rhtml code: <%= start_form_tag :action => ''update_cart'' %>

Hi all, I get an error when testing the "store_controller_test.rb" The troublesome line is in the test below: def test_add_to_cart get :add_to_cart, :id => @version_control_book.id <<< cart = session[:cart] assert_equal @version_control_book.price, cart.total_price assert_redirected_to :action => ''display_cart'' follow_redirect

Many of you probably know the ''depot'' app from the ''Agile Rails development'' book. I have constructed the ''products'' model, the Store-controller, and the ''Cart'' and ''Line Item'' classes. I have told Application-controller about :cart and :line_item: model :cart model :line_item Here''s part of

Hello everyone! I want to have login field in User model which is set only once (on create), and then it should fail validation if the value is changed. How can I do this? I dig around for validation and tried def after_validation_on_update unless User.find_by_login(:login) errors.add(:login, "is immutable. You can''t change it") end end in model, but somewhat it
