similar to: How to Validate Inherintly?

It seems to me that Validations are quite useful for many objects, even ones having nothing to do with ActiveRecord. Common examples are Contact Us forms, multi-step forms, web service paramater validations, etc. I took a look at the source for Validations, and it seems that it is very independent from ActiveRecord. I caught only three depenedencies: 1. validates_numericy --> depends on

Looking for some guidance/support on what feels like might not be an uncommon use-case. `User.has_many accounts` `User.has_many payment_methods` `Account.belongs_to :user` `Account.belongs_to :payment_method` `PaymentMethod.has_many :accounts` There are lots of `Accounts`. When I (a `User`) want to assign accounts to a `PaymentMethod`, I really don''t want to scope against all of them,

I''ve noticed that validates_format_of will return invalid if the field is nil. Question 1) How should we declare a validation that will validate it with a regex if it is set, but, if the field is not set, just move on Question 2) Why is it done this way? The other validators are only invoked if the field is set . If you want to declare the field mandatory, you add a

Sorry if I''m just dumbing out, but is there a reason that when using Single Table Inheritance Rails doesn''t really validate the "type" field or provide some mechanism to do so? seems like a good way to corrupt a database. Because the "type" is also a special attribute, I had to resort to an ugly hack like: class ActiveRecord::Base def type_attr

The original reason for this is because Ogg makes such a matter moot, since the bitpacker in libogg2 handles endian.. however, if a "chunk" packer is made available (similar to memcpy), this becomes important since

I started working on this in response to Dave Thomas'' keynote as RailsConf 2006. This little patch will validate that your text fields will fit into the database. Obviously this is just a start, and many more validations could be added. Also, this code could probably be extracted into a plugin instead of patch to ActiveRecord. Index: test/validations_test.rb

file_column is great -- but I need a way to run through the validations (ie: validates_file_format_of) before saving. That is, when a user first uploads an image it is displayed in the view but not ''saved'' until they click the ''Save'' button on the form. I want to display an error message/disable the ''Save'' button if the file they just

I would like to have a field on a form that does *not* have an underlying column in the table. Yet I would like to perform some validation on the value. I would like the results of the validation to show up just like the validations that are performed in the model. This is very similar to the password_confirmation field on a sign up screen. The password_confirmation is there on the screen, but

I''m having a problem with my User model. Originally I had alot of validation, including this: validates_presence_of :password_confirmation, :password validates_length_of :password, :within => 4..50 validates_confirmation_of :password However, this made it impossible to edit a user without setting his password, which I don''t want. So I tried to isolate the above validations

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, A few months ago someone posted a message about specifying validates_* constraints on a per-attribute basis. I just created a small plugin that allows you to do this. Here''s an example from one of my models: class Country < ActiveRecord::Base attribute :name, :string do |a| a.validates_length :within =>

Is there a decent log viewer for colorized log files? less -r for me doesn''t work well, as it sometimes clears the screen. I''d like: * Either a console type less viewer which just removes the colors * Or, even better, a console one which handles the colors without clearing the screen * Or, best of all, a GUI viewer - maybe even with color I use both Windows and Linux.

Hi, I have a <form> page in which there are a number of dropdowns and multi-selects, each of which is populated upon the page loading by quering its own table with the most recent values. These other tables are very simple two-column set-ups - one for the ID/value and another for the verbose description. I am getting the editing/creation stuff working fine. The dropdowns work with a

Can anyone enlighten me on how to make in_place_edit fields go through validations that are defined in the model? For example, my customer model has a "validates_numericality_of phone", but when the in_place_edit is done you can enter whatever you want. The field is defined as a string in the DB. I can''t change the database schema, due to other constraints, so I need a

I must create a class (JobClass) and include ActiveModel::Validations? and then valided = JobClass.new(params).valid? The JSON body : http://pastebin.com/TwRbydmq I can not create rules corresponding to the validation of the field "method" ... It can be "concat" or "split" but it is not the first level. How can I do? Thanks -- Posted via
