similar to: using database for validation

I''m trying my best to follow the skinny controller/fat model concept, and I''ve got a series of callbacks (that I''m about to move into observers) running on a few models. Based on what these callbacks do to the data (it''s implementing business rules), I''d like to add some type of message on the state of the model *without* invalidating it. For example:

All, I am attempting to do some custom validation on my object. Here is my validate method: protected def validate puts "Do I have the target_list_ids method? " + self.methods.include?(''target_list_ids'').to_s if target_list_ids.nil? || target_list_ids.length == 0 errors.add_to_base("You must choose at least one target list for this job")

Hi, Something has been bothering me about model validation: how do I know that the database has not changed in between when I validate my model''s data, and when it actually gets saved to the database? As a simple example, say I have a User model like: class User validates_uniqueness_of :username end When this gets saved to the database, the validation code checks that there is

Hello all ! I have a model being validated that spits it''s error messages on the resulting page using: error_messages_for(:mymodel) .... Basic stuff. It''s working perfectly. Now, I have something else I want to check on the same page (that isn''t an attribute to the Model)... and am trying to add it using: @mymodel.errors.add_to_base("another error here")

I am trying to write some simple code post a form, update the database and do some validation. I have 2 problems: 1) The validation fails but I can''t get hold of the error message 2) I can''t get the form to redisplay the previously entered data for the user to correct. I have 2 controllers: user and holiday. A user can request a new holiday by filling in a form. I have a

In my model I am using errors.add_to_base: errors.add_to_base "Error 1" This works fine. If I do this twice: errors.add_to_base "Error 1" errors.add_to_base "Error 2" I receive the message: translation missing: en, activerecord, errors, models, modelname, attributes, base, as part of my error messages. Anyone know how to get rid of this? Many thanks, Mike

Hi guys, I''m trying to do some validation on an image upload. Basically I have a model, Property, which has_many :property_images. I need to check that one image has been uploaded at least and so it was suggested I checked the number of images uploaded - @property.property_images.count > 0. Makes sense. I''ve added a validation on my Property model, like - def

Is there anyway to perform a query from within a validate function? I need to verify that the sum of several rows does not exceed a certain value eg: class Entry < ActiveRecord::Base belongs_to :day belongs_to :project def validate totalhours = hours samedayentries = self.find_by_day_id(day_id) samedayentries.each do

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

Hi: Passing child virtual attribute validation error to parent... in case of nested attributes. So, I have a Parent Model say ''Parent''. Nested Attributes it accepts for Child say ''Child'' Now suppose there is a validate method in ''Child'' and it has something like self.errors.add_to_base("some message"). How do you make sure that

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 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 have a very strange problem here. I do not get this. So any help is greatly appreciated. Basically I have a model that calls a method in the background process in the "after_save" method. Let''s call the model products. So what happens is this: 1. I create a new product. 2. Everything works and the product is saved with id 13. 3. A method is called in my background

Hi, AFAIK after_create is called after_save if the entry does not exist in the DB. Is there a way to tell if a specific model is new or not in after_save? I have to do something like: def after_save add_to_history ''save'' end def after_create add_to_history ''create'' end However after_save is called when creating too. -- cheers, M.

I am writing a library module to handle certain StatementInvalid type AR exceptions. I wish to catch the case where the db adapter in use is not supported by the module. I would like to test this situation and have only a vague idea as to how to proceed. My exception handling method selects the parsing method based on the adapter_name value. def hll_ar_exception(exception) raise

On a model I have the following simple validator: def validate unless name && name =~ /^\w+$/ errors.add_to_base("Name is missing") end end I would like to display a custom message on my views, without using the helper <%= error_messages_for "table" %> Where the messages from errors.add_to_base are stored and how to access them in the views? --

Hi, I am following the excellent tutorial http://www.railsforum.com/viewtopic.php?id=14216 (post 5) on how to implement an access control feature i.e. only a friend is allowed to view a profile of a particular member. I am not using the restful authentication plugin as the author is using to implement the authentication feature (post 1) in the tutorial. All I am interested in is the post 5

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,

Dear list, I am trying to override an after_save callback declared in main app using plugin. The main model class is: class WorkHours < ActiveRecord::Base @after_save_call_back_called=0 after_save :after_save_call_back def after_save_call_back logger.debug "after save called" @after_save_call_back_called=1 end end And in my plugin (in the lib directory) : module

With my functional tests (on PgSQL) I get strange errors like this 1) Error: test_create(AufgabeControllerTest): ActiveRecord::StatementInvalid: ERROR: duplicate key violates unique constraint "aufgaben_pkey" Tracking this down, I found that sequences are only reset for some of the tables I''m using. The reason? Inconsistent singularization. I won''t go so far as
