similar to: nil instead of empty string

I am just getting started with Rails, don''t know any Ruby, and don''t quite even get object oriented programming yet. I have tweaked my schema to The Rails Way and have generated a bit of scaffolding. I am trying to create a new Part, which references a PartName and a PartNumber. I can create a PartNumber on the fly, but the PartName has to exist. I have an inelegant solution

Is trhere any way how to support allow empty? Rails prefer empty string than null for database and then validations with allow_nil fails. -- Posted via http://www.ruby-forum.com/.

I''m hoping there''s an easy way to do this.  I''m trying to read options from a database, and insert them into form tags.  So for example, In the Database Table: options size: 300 type: text_field maxsize: 300 and I want to create a text_field form tag, with all the appropriate options, is there an easy way to do this, other than having the code output the HTML

Hi, I am sorry for maybe stupid question. I am new in rails. I am trying to create very simple weblog systeme. I know threre are plenty of them, but It''s good to study. I create following rule in models/post.rb validates_length_of :header, :in => 3..50, :allow_nil => false, :message => "At least 3 characters" It''s working fine with default scaffolt add

Just got around to understanding your idea Rich. Your idea seems to apply to every controller with new/edit/show views, so I think this is a better idea for the edge rails folks to implement generically than for a newbie like me do as a one-off.

I have a model that uses attr_accessible, and in my tests I get this: RuntimeError (Declare either attr_protected or attr_accessible for User, but not both.): /var/lib/gems/1.8/gems/activerecord-2.0.2/lib/active_record/ base.rb:2307:in `remove_attributes_protected_from_mass_assignment'' /var/lib/gems/1.8/gems/activerecord-2.0.2/lib/active_record/ base.rb:2114:in

Hi all, In my shop application I have created a form (rhtml file) containing both address and order information. I created my fields: like the following: For address info: <%= text_field ''address'', ''postalcode'' %> For order info: <%= text_field ''order'', ''email'' %> However when the following action gets

It appears that if your trying to use validates_inclusion_of for a string value allow_nil wont work. For example, if I have an attribute :year which is stored as a varchar then: validates_inclusion_of :year, :in => "1980"..Time.now.year.to_s, allow_nil=>true will successfully validate the range but will not allow an empty input field to be submitted. However, if :year is

Hi, I use scaffold to create the task model controller and view, it contains action as "show", "new", "create", etc. Then, I give an "id" parameters to the view - new.rhtml, so the URL could be like "http://localhost:3000/tasks/new/1" , and I wish when I click the create button in "new.rhtml", the following "create"

Hi all I have the following Model: Member(id, username, first_name, last_name, hashed_password, password_salt) Now I want to allow users to register for an account using the following form: --- <%= form_tag %> <%= error_messages_for ''member'' %> <p><%= _(''Username'') %>: <%= text_field(''member'',

Leaving the body of the method the same as the default still throws the "stack level too deep" error. As a matter of fact, it only disappears if I comment out the ''require'' in line 1. As it turned out, it was the method definiton itself that caused problems. Ruby doesn''t have keyword arguments, but I tried calling the method as if it had. But when I changed

I think I must be doing something wrong... when a form returns params to the controller, empty fields appear to be returned as blank, not nil. so what''s the point of an :allow_nil=>true setting on a validation? it fails because blank is not the same as nil. i would expect either returned empty fields to be nil, or :allow_nil to really be :allow_blank. otherwise i have to do a search

I have an address model and am doing some validations. One of them seems to ignore :allow_nil => true. If I leave the phone input blank, I get it back with a "too short" error. Here''s the relevant parts of the model: 1. class Address < ActiveRecord::Base 2. 3. validates_length_of :phone, :in => 7..10, :allow_nil => true 4. 5. before_validation

Hi, I submitted a patch (for the first time) a couple of days ago (http://dev.rubyonrails.org/ticket/5091 - the decsription is included below). I''ve noticed some posts to rails-core notifying the world of patches, since there''s been no activity on said patch I thought I''d do the same. Please let me know if this breaks protocol.

Hi, I'm seeing a strange problem with some attachment filenames that are UTF-8 encoded. The problem seems to be related to spaces and/or unusual characters in filenames, like accented characters (or perhaps just to filenames if UTF-8 encoded; I've not explored that fully). These filenames are shown as empty strings in IMAP using Dovecot. I've attached a sample message that exhibits
