similar to: validation error reporting on child object

I can''t seem to figure out how to get child validation error messages to display. I''m going through the simple blog example DHH uses in his video. In the example, a comment belongs_to a post. Validating posts works fine and the errors are displayed as they should be. When I try to validate a comment using: validates_presence_of :summary It does the proper validation by not

Hi All, I am just trying to learn ruby/rails so please don''t flame me if this is a stupid question. As a learning project I decided to create my own blog using ROR. I have created a controller that shows paged blog entries, and below each blog is a list of comments along with a form alowing the user to add a new comment. To create the form for the comment entry I used form_for

I want to know the standard/easiest way to add items to a parent? Example: comment added to post I would like this to happen in the ?show? view of post using a form that is shown when the user clicks the ?add new? button/link. I would also like validation on the child form with the validation errors appearing in the post show? view. Two problems are presented: 1) When the user clicks the

Okay, this is something I run into a lot and don''t really have a great solution. Here is a simple example: class Blog < ActiveRecord::Base has_many :posts validates_presence_of :name end class Post < ActiveRecord::Base belongs_to :blog validates_presence_of :name validates_presence_of :blog_id end Now, if I want to create a blog and post at the same time I

Hello Folks, I am starting out with RoR and just browsed through Dave''s book ? couldn''t stop reading. I started building a prototype to get better hands on experience and I have run into two simple issues that I am hoping will be a quick answer for some of you experts out there. *Issue 1:* >From within a "companies" controller and list_companies.rhtml view

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 am trying to create a record with association. Within the create method, I would also like to pre-populate dependent (has_many) records from a template in the database. The child records are <u>mysteriously rolled back </u> if I insert them in a loop. If I try to insert a single child record, it works.I have read the books and tried to google my way out of this but am at a dead

I''m trying to assign a parent foreign key value using collection_select from my child "new" form. The problem I''m having is if I do not make a selection, I get the following error instead of the Rails validates_presence_of error: You have a nil object when you didn''t expect it! You might have expected an instance of Array. The error occurred while evaluating

Hey All, I have a form that submits data to multiple models. I have class Man < ActiveRecord::Base has_many :notes has_many :contacts validates_associated :contacts, :notes validates_presence_of :first_name validates_presence_of :last_name class Contact < ActiveRecord::Base belongs_to :man validates_presence_of :contact_info class Note < ActiveRecord::Base

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

Please help, I am really at a loss at how validation is supposed to work in rails. Model contains acts_as_tree I want to force my NEW objects to have a parent I do NOT want existing object to have a parent so I only want to have parent_id on create, NOT on update. I am trying this: def validate_on_create validates_presence_of :parent_id, :message => "You must specify a

All, The validation on my object is not being triggered any more on the save action. I''m trying to debug it. In attempting to debug it, I''m trying to understand exactly what validates_presence_of does. Basically, I''m trying to see if for some reason, validates_presence_of doesn''t think my fields are blank now. I see from the API docs. that

I have two models bank and country. User should only associate a Bank with a country id present in the country table and I put validates presence of country to enforce it but i get error mysql2::Error: Unknown column ''countries.bank_id'' in ''where clause'': SELECT `countries`.* FROM `countries` WHERE `countries`.`bank_id` = 17 LIMIT 1 when updating the bank

Hi, I''m having a weird validation issue. Validation isn''t working for certain attributes and, for some reason, it''s also affecting things outside of validation. For campers on certain camp types, we require some information about their school. I tried to validate the information this way: validates_presence_of :school_type, :if => Proc.new { |c| !c.booking.nil?

ActiveRecord validation messages are currently not I18N-friendly. Specifically, I''m referring to the fact that it enforces a certain grammar, namely the beginning of the message must consist of the field name. For example: validates_presence_of :name, :message => "can''t be blank." ...generates the message "Name can''t be blank". This grammar

Hi, I''d be grateful for your help. I get the error (see below) everytime I add the following into a newly generated (via scaffold) model class: validates_presence_of :myname, :mymessage, :mytel Without it, I can insert records into my database. With it, I get the error :( ERROR>> ArgumentError in AdminController#create wrong number of arguments (1 for 0) RAILS_ROOT:

Hi: Passing child virtual attribute validation error to parent... in case of nested attributes. So, I have a Parent Model say ''Parent''.

I''ve been banging my head against the wall trying to update a table (add/delete rows) using Ajax. It seems simple enough but just doesn''t work for me. I can get it to work using DIVs instead of a table, but doing the layout with DIVs is much more cumbersome and I know it works for others with a table (though I haven''t been able to find an exact example code anywhere).
