validates_format_of :kulcsszo, :with => /[\,\;\.\!\?\|\\\(\)\/]/

This in fact does the opposite. It checks if the kulcsszo field does include the said characters.

I can't find a way to negate this, so the validation would pass only if /[\,\;\.\!\?\|\\\(\)\/]/ does not find anything, meaning the kulccszo does not contain any of the said characters.

Long story short: how do you validate the exclusion of some characters.

Thanks a lot.

It's my first time posting here,I'm a newbie on rails I need help on my installation for RoR.I worked for a weeks to make the rails installation success but fail.I thought it was not compatible with fedora or something.Then I tried with virtual one,and it work amazing.

The problem is :
I keep getting this error:
[root@alifazman bin]# gem install rails
/usr/lib/ruby/site_ruby/1.8/rubygems.rb:9:in `require': no such file to load -- thread (LoadError)
    from /usr/lib/ruby/site_ruby/1.8/rubygems.rb:9
    from /usr/bin/gem:8:in `require'
    from /usr/bin/gem:8

I just don't know what happening.After many time I tried to configure it,also by uninstalling it many time.and Install it step by step as instructed by the tutorial on wiki rails.I'm loss.Hope you guys can help me out..

Thanks in advance..

I am a newbie. I have been playing only using 1 controller and 1 model.. Any examples out there that I can go beyond this...
I think an a deeper understanding of MVC is also required.

Any recommended readings and links????

Thanks

Each of these is a "product" but will obviously have different attributes.  I'd like to be able to add a new product (with common attributes like name, description, category, etc).  Then based the product's category, I want to be able to fill in the other attributes as needed for that category.

Option 1: Use Single Table Inheritance
I looked this up on the forum and elsewhere and saw references to Single Table Inheritance as one possible option.  But it seems like that might not be the best approach since, over time and with a large number of categories, that would lead to a huge table full of attributes.

Option 2: Use Multiple Models for Each Type of Product
I could also create models for each type of products (Camera, Phone, Book, etc) but I'd like to be able to add new categories/products from within the admin area of the site once it's live vs. having to dive into the code each time I want to add to the site.

Questions:

1. Any idea how to setup something like this in Rails or any other options I should consider? 

2. And is there another concept I'm missing that I should read up on besides Single Table Inheritance that would help point me in the right direction?

Thanks

I am using the paperclip plugin to upload images and it works absolutely fine.

I intend to save my uploaded images to C:\Application_name\public folder. Accordingly, with some study over the i-net, I changed the :path option of has_attached_file to -

:path => "C:/Application_name/public/:class/:attachment/:id/:style_:basename.:extension"

Now, the files are being saved to the desired path. However, I need to understand what should be the corresponding change in the :url option.

I tried everything -

:url => "/:id/:style_:basename.:extension"
:url => "C:/Application_name/public/:class/:attachment/:id/:style_:basename.:extension"
:url => "/public/:class/:attachment/:id/:style_:basename.:extension"

but none of them work. The image couldn't be displayed.

Request, please share any inputs which could help me further to this.

Thanks in advance.

Aal izz well...:-)

What can i do so that the input and button fill 100% of their containing cell?

I have a simple app that only requires one user to login and perform certain admin tasks.

What is the best way to set this up. I'm used to using acts_as_authenticated and Clearance in various other projects but this seems like overkill here.

Thanks

Can anyone offer up an explanation or suggest somewhere i can look for answers. I've tried an apache restart today and i'll keep an eye out to see if the dev log gets written to again. It's running on rails 2.1.1. and passenger 2.0.3 fwiw

Its the one they use in the Creating a weblog in 15 minutes screencast

def minimum_age_conditions
   ["people.age >= ?", minimum_age] unless minimum_age.blank?
  end

  def maximum_age_conditions
   ["people.age <= ?", maximum_age] unless maximum_age.blank?
  end

But instead I have person.birthdate and the age is calculated

def age
    return if birthdate.nil?
    today = Date.today
    if (today.month > birthdate.month) or
       (today.month == birthdate.month and today.day >= birthdate.day)
     #birthdate has happened this year
     today.year - birthdate.year
    else
     today.year - birthdate.year - 1
   end
 end

How can I go from person.birthdate to a range of ages from search?

ruby script/generate scaffold 'blog/post' string:title text:body

This created a posts_controller within app/controllers/blog, model posts.rb in app/models/blog and a table blog_posts in the database. The contents of the controller and are:

# app/controller/blog/posts_controller.rb
class Blog::PostsController < ApplicationController
  # REST actions
end

# app/models/blog/posts.rb
class Blog::Post < ActiveRecord::Base
end

# config/routes.rb
  map.namespace 'blog' do |blog|
    blog.resources :posts
  end

When I ran rake routes, I got the following:

    blog_posts GET    /blog/posts(.:format)               {:controller=>"blog/posts", :action=>"index"}
               POST   /blog/posts(.:format)               {:controller=>"blog/posts", :action=>"create"}
 new_blog_post GET    /blog/posts/new(.:format)           {:controller=>"blog/posts", :action=>"new"}
edit_blog_post GET    /blog/posts/:id/edit(.:format)      {:controller=>"blog/posts", :action=>"edit"}
     blog_post GET    /blog/posts/:id(.:format)           {:controller=>"blog/posts", :action=>"show"}
               PUT    /blog/posts/:id(.:format)           {:controller=>"blog/posts", :action=>"update"}
               DELETE /blog/posts/:id(.:format)           {:controller=>"blog/posts", :action=>"destroy"}

But when I go to http://localhost:3000/blog/posts, I get the following error:

Mysql::Error: Table 'myproject.posts' doesn't exist: SELECT * FROM `posts` 

It's looking for a table called posts, but I need it to use the blog_posts table. Could somebody point me in the right direction, please?

And finally, the small problem that I am yet to fix. In the setter method for the virtual attribute contact_name, i need to scope the query through current_user. but current_user is a helper method. And the params hash(which carries the current_user_id in my case) too is not available in the model. Hope someone can help me out with that. Details here.

I don't know what to call this or where to look. After googling for a while, the best I could find is that it might have something to do with active record. Am I in the wrong place? If so, do you know what I am talking about and can you offer some suggestions?

Now, I place my files on the server for production environment mode which is in Ubuntu. I have my rails to version 2.0.1 and my roo to 1.9.2 and 1.2.0
