similar to: scaffold.. random error

I''m attempting to learn Ruby on Rails, but these errors aren''t helping. I''m currently trying to follow the lessons available on www.learningrails.com. I received this error after trying to visit a page generated by using the scaffold command. Actually, this is all I did up until the error: rails sample2 -d mysql mysqladmin -u root -p create sample2_development ruby

I am creating a database for movies (films) and television shows (shows) that will have has_and_belongs_to_many relationships with the pictures table. CREATE TABLE screenshots ( id serial NOT NULL, filename character varying NOT NULL, content_type character varying NOT NULL, primary key (id) ); CREATE TABLE films ( id serial NOT NULL, name character varying NOT NULL,

I''m trying to use new_equipment_path, which creates the appropriate link. But, when trying to evaluate "equipment/new" I get the error below. I''ve included my routes (rake route). Equipment is one of those words that pluralizes to "equipment", so the singular is right (from what I know from this forum. Any help would be appreciated. Error: equipment_url

Preface: I''m trying to find my way through the "Build Your Own Ruby on Rails Web Application" book. I''m completely new to programming and am having a hard time figuring out the differences between rails 2.0.2 and what''s in the book so please forgive me if this is a stupid question. I''m confused because I finally thought I''d figured out the

I want a scaffold to manager both products and users. To get the products scaffold I used script/generate scaffold Product Admin if I use, script/generate scaffold User Admin will it overwrite my product admin controller? Would I be better off doing script/generate scaffold User User_Admin or something? -- Posted via http://www.ruby-forum.com/.

Apparently a scaffold creates at least one instance variable for views to use, and if I override the scaffold then I must also explicitly create that instance variable for the view. I''d like to know exactly what work is performed by the scaffold so that I can know this when over-riding the view. (OR, is it that the controller makes these variables available by default?..) EXAMPLE:

Hello all. I''ve got the following in my model: class Individual < ActiveRecord::Base validates_presence_of :first_name, :last_name, :street, :city, :state, :zip validates_acceptance_of :AZ_resident, :message => "You must be an Arizona resident." end The AZ_resident field is present and defined as boolean (PostgreSQL 8.1), but validation will not occur.

Hi everyone, I''m a rails & ruby nuby, and this is my first post to the list. Here''s my environment in case it helps diagnose my problem: Ruby version 1.8.4 (powerpc-darwin8.6.0) RubyGems version 0.8.11 Rails version 1.1.2 Active Record version 1.14.2 Action Pack version 1.12.1 Action Web Service version 1.1.2 Action Mailer version 1.2.1 Active Support version 1.3.1 I did

there are some things on a scaffold that i would like to use without the whole thing. is it better to generate one and then cut it down to only what you''ll use? are all of the things in a scaffold available to just build by hand? for instance, i have a scaffold for my users. in the list action, it has @user_pages, so that you can put @user_pages.current.next or something like that -

I am attempting to generate scaffolds on legacy tables that have underscores in the name. Scaffold does not see the underscore. I have tried a backslash escape but it no work. I have looked around but i cannot find a way to make it work. It''s like this: c:\railroad>ruby script/generate scaffold FOO_BAR exists app/controllers/ exists app/helpers/ create

I know the scaffold generator is really only useful for beginners and/or very the preliminary state of a project, but I find that I use it a lot (especially, since I am still a beginner). There are a couple of things I find myself tweaking (or wanting to tweak, but never getting around to tweaking) each time I generate a new scaffold: 1) Change the layout from blah.html.erb to

How do I get scaffold to generate code for a table whos name is not plural of the modelname I give to it. I.E., If I have an existing database, and wish to generate scaffold code for existing tables, is this possible??? _______________________________________________ Rails mailing list Rails-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org http://lists.rubyonrails.org/mailman/listinfo/rails

Would anybody know why I get this error from this bit of code: class LocationsController < ApplicationController def index scaffold :locations end end This is the way that is demonstrated in the screencast for creating a quick scaffold. I have done this before. However, I come back to working with Ruby after about a month on something else and now it gives this error. Any

I''m doing very well with the Hibbs Rolling on Rails tutorial. I have an easy question for my personal notes. I''m coming up with a simple framework of steps for creating a basic database. It includes the following maxims to make original app creation easy: app_name = MySQL database name SQL_tablename = model_name model_name = controller-name Is this going to work for getting

Hi, I''m trying to get through the popular "Four Days with Rails" tutorial and am experiencing some problem with the "Priority" of the item. Right from the start, RoR seems to want to consider it as a value that must be boolean. The scaffolded code asks for "True/ False" as the input. PHPMyAdmin shows that the database thinks it should be an unsigned

Is there any reason that foreign key fields do not show in any of the scaffold views ? project table: id serial primary key, category_id integer, user_id integer, name varchar, morestuff varchar foreign key (category_id) references categories(id), foreign key (user_id) references users(id) scaffold generated views only show name, morestuff fields

Hello everyone, I am developing my application and I created a scaffold called listas, but when I acess /listas/new I get this error message: NoMethodError in Listas#new Showing /home/rodrigo3n/code/listeiroo/app/views/listas/_form.html.erb where line #15 raised: undefined method `deep_symbolize_keys'' for nil:NilClass Extracted source (around line #15): 12: <% end %> 13: 14:

Hi, first of all I will apologize in advance for my presumably noobish question, but I''m only starting to learn Rails and am a little confused with all the changes in 2.0.1. There are as good as no tutorials out yet and the 2 or 3 screencasts I''ve seen deal with the creation of both the app and the database. Now my problem is that I already have a database with a fair amount of

Hello All! I''m novice at ROR. Would you like to explain what mean such constuction in Ruby. 1: class DemoController < ActionController::Base 2: scaffold :item 3: end Is 2th line calling of method ''scaffold''? If it is so, when it called? For all instances of class, or only for class? I watch sources of ActionController, but don''t understand completely.

I''ve got a database with several tables. I''d like to create scaffolding for separate CRUD interfaces for several of these tables. I''m hoping that the scaffold generator can create the CRUD code for all these tables in ONE controller, but I don''t know how to tell it to do that, if it can. Can anyone verify if this is possible?
