similar to: Child to Parent Validation Errors

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

How does one deal with validation error messages on child objects of the main model object behind a page? I have the basic blog w/ comments page (only my "entry" is a "proposal"). I have the comments saving just fine, but I wanted to show an error if the user hits the submit button without typing anything in the comment. I added "validates_presence_of

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

What are the limitations on using: errors.add_to_base to display errors in views? I have tried for days to add errors from my object.rb and they never get displayed. class Keyword < ActiveRecord::Base validates_presence_of(:name, :message => "Name is required.") validates_uniqueness_of(:name, :message => "This name is already in use. Please try

Here''s a snippet of my model: validates_presence_of :from_name, :from_email, :reply_name, :reply_email, :eSubject protected def validate puts "Calling: #{target_list_ids}" errors.add_to_base("You must choose at least one target list for this job") if self.target_list_ids.nil? end It appears that the validates_presence_of are being called just fine,

in testing my app I just use the validations validates_presence_of :first_name, :last_name, :email validates_presence_of :academy, :message => "You must select an Academy" validates_presence_of :role, :message => "You must select a role" standard error_messages are fine for most of my fields , resulting in : 5 errors prohibited this data from being saved There

If i have a parent that has_many :children, and the child belongs_to :parent. Then when I add a new child to the parent like so: parent.children << Child.new, then shouldn''t the child also have a reference to the parent? but it doesn''t-- child.parent is nil-- what''s going on here? is this as it should be-- shouldn''t it have a reference to the

i have the problem that my child class fileds aren''t validated on saving the parent. working with parent and child works without problems. if all fields are filled correctly everything is saved as expected. but missing fields in the child arent added to the errors. following short sample shows what i try: Model ----------------------------------------------------- class Parent <

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

validates_presence_of :fname results in the error message "Fname can''t be blank". What I want is "First Name can''t be blank". I could do this def validate errors.add_to_base("First Name can''t be blank") if fname.blank? end I find this clunky and I have to put everyrhing in the validate method. Is there an easy to get what I want. I

Hi all I have the following model: class PhotoGallery < ActiveRecord::Base attr_accessible :title, :description, :file_path, :title_photo_id has_many :photos, :dependent => :destroy belongs_to :title_photo, :class_name => ''Photo'', :foreign_key => ''title_photo_id'' validates_presence_of :title, :description, :file_path

I''ve been playing around with the idea of using the database for model validation where possible (instead of duplicating that validation in rails). My first approach to this was to catch exceptions from save/ create and parse the errors, in my case from postgres, to turn them into something friendlier. Something like: def update create end def create begin super

Given the case of validating the presence of an attribute and then performing other tests on said attribute, how do you go about not having to check for nil in the other tests? Example: validates_presence_of :start_date, :end_date validate :validate_start_date_before_end_date def validate_start_date_before_end_date # without this check an exception will be thrown on access to the

I''ve got a really strange problem using belongs_to. I apologize in advance for the length... this is going to take a while to explain. Basic idea: Creating a User requires that the user enter an email address and activation key that matches an existing PendingUser. After creating the user successfully, that pending user should be marked as "used". The problem: When I

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?

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

I''m having trouble with a validation that depends on an attribute of a belongs_to parent. If the child is added to an unsaved parent (parent.children << new child), the has_many collection parent.children includes the unsaved child. However the belongs_to attribute child.parent appears to be nil until the parent has been saved. Without access to the parent attributes, the validation

Hi guys, I was trying to create a record in both the parent and child tables (1 to 1 relationship). By default when you call parent.save it''s not invoked in a transaction mode, and I''m trying to avoid parent record is created without the child record (due to validation error in child). I wanted to save both parent and child in transaction mode: parent = Parent.new child =

Hi! I''m struggling with it for a week. I posted a few similar posts that cleared up few things (thanks Mark!), but i still don''t know how to do it properly. What i''m trying to do is to create parent object and its many children (images - i tried using file_column, but it''s a topic for another post)using data from a single form. I''ve got a working

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
