similar to: boolean db fields set to false fail validation with validates_presence_of?

This almost feels like a bug to me, since false is not nil. (i don''t think!) Using v_p_o on a boolean field fails validation if the field is passed with ''false''. It passes validation in the case of true. How can I validate _presence_of a boolean if it is submitted false? -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~

Hi, guys, I''m learning to use Rails, and, while reading the "Rails: Up And Running" book, I tried to make an insertion validation, using the following code: class Photo < ActiveRecord::Base validates_presence_of :filename end It simply didn''t work, the validation does nothing and an insertion with an empty field returns TRUE. What''s wrong?

Is there an expert validater that can point me in the right direction? I''ve looked for extended documentation on ''validates_presence_of'' but i can''t seem to find any.

Ok, this should be simple but I am finding it''s not and previous postings don''t seem to shed too much light on this.

Has anyone figured out a way to get validates_presence_of to work with float, boolean, and integer fields that are defined as non-null in the schema? The problem is, ruby intializes these types to the default schema value, which for mysql is never null if the column is not allowed to be null, and as a result they are initialized in the form with a value, and are never null. I found a work

Hi all, I just begun with RoR and going through the Agile development w Rails depot example ATM.

My Product model looks like: class Product < ActiveRecord::Base

Is it possible to change error messages for Validation helpers? I am writing an app against a existing database (so no control over column names), but when there is validation error (e.g. with validate_presence_of) I would like to customize the field name.

Hi all, I am using "validates_presence_of" for validating all fields of my registration form. It is working fine and generating custom error message as mentioned. Also clearing all fields.

I have a form with 3 fields: user_id, email and password. All 3 fields are required, so I have a "validates_presence_of :user_id, :email, :password" in my model. Works, but the validation errors show up in a different order than I specificed in the validates_presence_of statement. Is there a way to specify the order in which the validations (and corresponding error messages) should

I could be going mad and missing something really obvious here but I''m getting an unexpected result from the following.

I have a rather complex object with a number of attributes. For a variety of reasons, I would like one view to create the object with only a couple of fields completed, then a second and third view to finish all the fields. I would like the model to validate_presence_of all these fields, since eventually I need them all there, and I would like each page to validate its portion of the fields that

Last night a friend of mine started ranting about validates_presence_of :boolean_field returning not valid when the boolean field is false. I checked the rails issues and this seems to be a pretty common concern about the naming of ''presence'' . Instead of changing the behaviour of the presence validator, I was wondering if maybe the answer to avoid such misconceptions could be
