Hi! I got a class named EinsatzFilter which I serialized to session. Before saving to session it works afterwards I keep getting the message: "undefined method `to_s'' for #<Person:0x38c6ab8>". "Person" is a from ActiveRecord::Base inherited class. Code: class EinsatzFilter include ApplicationHelper attr_reader :personen, :monat, :projekte, :kunde

There''s a small inconsistency in ActiveRecord''s callback syntax that has tripped me up before. It wouldn''t be a big deal, but it can lead to a silent failure. I''d like to suggest that it either be made consistent or be made to fail loudly. The issue is that to do something before validating, but only when creating, you use `before_validation on: :create`,

Hi All, Is there a way to filter / modify the output of a model class before it''s returned to controller/view that''s calling it?

Hi, there must be something wrong somewhere in my unit test because there''s a model I can''t have any callback executed on. In my unit test I do @image = Image.new @image.set_uploaded_file({:file => uploaded_file("pic1.jpg","image/jpeg","article-picture.jpg"), :article_id => @article.id, :title => ''Titre

I have an Order model with a ''status'' column. What I want to be able to do is validate that the status of the Order is not completed before it is allowed to be deleted. I tried the following method in my Model, but it appears that this only works for an :update or :create on the record. Anyone know how to do this, and if it should be in the model or the controller?

Rails has many built in validation methods to ensure that an ActiveRecord instance cannot be created or updated under certain situations (typically caused by invalid data). However, I can find no methods to govern whether an ActiveRecord instance can be destroyed. Essentially, I wish an error to be raised when a user tries to delete an ActiveRecord without first adhering to a certain set of

Hi, I am trying to validate a numeric value passed in from a form, which is saved in a MySQL db as decimal(9,2) Now problem is I need to ensure people don''t enter a form value like -. 003. In my validations, I have a validates_numericality_of check being done. Furthermore, in validate method, I have a check using an if statement such as : ((an_object[n].nil? or an_object[n] < 0) and

What''s the best way to validate_on_destroy. Rails only seems to include validate_on_create and validate_on_update methods. I don''t want to resort to doing: before_destroy do |j| raise "There is an error" if j.etc end Is there a way of finding out what action (create/update/destroy) is being performed if I use the ''validate'' method? -- Posted via

e.g. class Asset < ActiveRecord::Base validates_presence_of :asset_number, :make, :model, :location, :name, :serial_number validates_numericality_of :asset_number validates_uniqueness_of :asset_number belongs_to :user belongs_to :location belongs_to :asset_type, :foreign_key => ''type_id'' end class Location < ActiveRecord::Base validates_presence_of :name

In ActiveRecord''s callbacks, methods within a before_create callback are called after the validation, but before the model is created. This was an intentional design decision, but I think it was the wrong one. What do you think? When I think of before_create, I think of before_validation :foo, :on => :create, but, by default, before_create is synonymous with after_validation :foo,

Hello, I needed to add custom cache field for one of my application. I thought I will share the code showing how to do this. This code below creates and maintain a custom cache field, for keeping track of totals.

How would I stop the last user being deleted. The following code doesn''t work. before_destroy :dont_destroy_last_user # Don''t delete user if it the last one def dont_destroy_last_User raise "Can''t destroy last user" if User.length < 1 end -- Posted via http://www.ruby-forum.com/.

Hi all, For various reasons I need to have foreign keys with not null constraints. Eg: create_table :people do |t| t.column :name, :string t.column :household_id, :integer, :null => false end create_table :households do |t| t.column :name, :string end add_foreign_key_constraint :people, :household_id, :households, :id So the people table has a foreign key into

Hi all, I''ve got a form which accepts a "price" field and I''m attempting to validate it and allow some flexibility in the way the user enters it.

Hi all My visitors can create party organisator profiles, and I want assign them as the creators (the field creator_id in the organisators table references a member in the members table). To do that I tried it with before_validation: def before_validation creator = Member.find 1 end Sadly, this does not work. The validation validates_presence_of :creator_id Still tells me, that

Hi, I was looking around a bit and couldn''t find any callbacks that executed before before_validation The current problem with using before_validation is that it won''t fire if I''m not using validations with #save(:validate => false) - which makes sense. Before_save won''t suffice because I want these callbacks to fire before validation on the occasions that
