similar to: Tableless ActiveRecord attribute and my aching head

Ive followed this example of how to validate a form with a tableless model: http://rails.techno-weenie.net/tip/2005/11/19/validate_your_forms_with_a_table_less_model Ive got this example working but when validation fails the failed boxes are not highlighted in red. At the moment i have a contact details form and want to validate the information entered by the user but this will just result

All - Trying not to fight rails on this, basically have a form and all the same as would be with an ActiveRecord model except that there is no table. I started out using this article: http://stackoverflow.com/questions/315850/rails-model-without-database ...which is kind of a hack by inheriting ActiveRecord in to non-AR model but am running into some problems and just have the feeling that I am

I have a problem with ruby on rails validation total_book_toy.rhtml ================ <%= text_field ''book1'', ''title1'' %> <%= text_field ''book2'', ''title2'' %> I want to validate these text_field so user can''t insert same title. However, I was stuck how to do it. Or maybe you have another way how to do it.

Hello! I''ve modified ActiveRecord a bit to support enum columns. This is tested only with MySQL, and maybe needs some changes for other adapters (if they use another syntax or quoting style). I believe this patch should be tested well, so I haven''t (yet) tried to post it to the official Trac. It is also not solid-as-a-rock when it comes to quoting ENUM values. After

Hi, in the past few months someone posted an entry on their blog about how to do validations in non-AR classes and I cant find it any more. Anyone have a link? Thanks, Trevor -- Trevor Squires http://somethinglearned.com

Hello, I am a developer who has just started working on a large scale website in a team of 5 other developers. One of the developers has introduced some enum columns into the the database. Now, by default, active record doesn''t support enum column types but I have added the enum-column plugin into our project. This has worked very well except for a few instances where he

Hi, I ve got oracle database which exists prior to my rails app... :-( I ve got trouble when I am updating/inserting records of a table which includes nvarchar2 attributes. These have a specific maximum length. I often get an error Value too long for column when doing my inserts/ updates, but in fact that is not the case. I ve taken a look at the generated sql statements.... As far as I know

I know that Rails doesn''t handle database ENUMs. I''d say that 9/10, you can get away with just using varchar instead. However, there ARE instances where you need certain functionality that ENUMs provide (ie: integrity at the datalevel). I have a working function that will show what enum types are available for a certain column in a table (I believe this will only work for

The revised patch submitted on #4748 broke the build, I''m looking to sort out why. Also note that this auto-test email didn''t make it to rails-core because it was too big (every test failed, so the resulting email was huge). I''ll patch my auto-testing script to truncate the email to no larger than a few kb. Michael Schoen wrote: > "marcel" made

Hi you all, I have a model simulating an ActiveRecord model, according to the tips stated in [1]. It is simulated because even though I am gonna save the attributes in a file, not in a DB, I still want the validations made by ActiveRecord::Base (see code below). Well, the thing is that I also want the behaviour of the created_on and updated_on columns, that get modified automatically before

Hey everyone I''m building an application that is using a mySQL SET datatype sad The problem is that ActiveRecord thinks this is a date! Here''s the relevant output from Model.columns: #<ActiveRecord::ConnectionAdapters::MysqlColumn:0x351b488 @primary=false, @scale=nil, @sql_type="set(''Any'',''Grade School'',''High

In order to coerce Rails 1.2.x into supporting Unicode values for an attribute in a model, I found I had to do the following: 1) Change the underlying column type from varchar to nvarchar. 2) Prepend any quoted values going into nvarchar columns with a capital-letter-N, e. g. ''unicode'' becomes N''unicode'' In order to accomplish this, I modified

I am trying to create an application loosely based on the Depot application presented in Agile Web Development with Rails (AWDwR). I am using InstantRails for the server. In my app I have the folowing controllers: admin_controller application_controller city_map_controller (with method: displayGMap) The admin_controller was created with the following command: ruby script/generate scaffold

I''m using a legacy table, where the unique id is not ''id'' I have a Model class like the following: class Article < ActiveRecord::Base set_primary_key "ARTICLE_ID" end however, using a link_to like the following (modified scaffolding), the link has no id value: <% for article in @articles %> <tr> <% for column in

What do you prefer/recommend for double-banger function names: 1 scale.colour 2 scale_colour 3 scaleColour 1 is more R-like, but conflicts with S3. 2 is a modern version of number 1, but not many packages use it. Number 3 is more java-like. (I like number 2 best) Any suggestions? Thanks, Hadley

Hi, I''ve a model that is stored to the db, but just one of its atribbutes doesn''t have a corresponding column on the table (it is used just for a calculation and still requires validation). I''ve been succefull by doing what is explained in http://rails.techno-weenie.net/tip/2005/11/19/validate_your_forms_with_a_table_less_model But I get an error of a non-existent

I have a question, I have to provide a solution for an office that will be almost abandoned, and there will be one or sometimes two persons 2 days a week. The main number however should be preserved. They have several ISDN BRI connections, most of which will be dropped. Only one will be retained, for 2 reasons: 1) It has the ADSL link 2) The number has been the main contact number for over 20

I''m trying to get started with Rails, but I''m running into a few places where I''m having trouble understanding the expected workflow. I''m trying to work with migrations from the beginner; its a port of an existing application, but I''d like to let the db schema evolve as the application grows, so I''m starting from an empty (tableless) database.
