similar to: Compute date during before_validation_on_create

Hi List, I have one column of beginning dates and one column of ending dates, I want to find their difference. And I want to ignore the trailing zeros, basically everything after the first colon mark. Begin_date End_date 01JAN2000:00:00:00:000 02FEB2002:00:00:00:000 24MAR2012:00:00:00:000 18MAY2012:00:00:00:000 01OCT2003:00:00:00:000

I''m having fun composing queries with ez_where, but am stuck on how to formulate the following using the ez syntax: (begin_date >= ? OR end_date >= ?) AND (description LIKE ? OR name LIKE ?) There are two clauses, each containing OR operators (the ez ''any'' syntax) but both clauses must evaulate to true for a match. Can anyone suggest the proper way to construct

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,

hallo, everyone can anybody help me? i did add my code under ENGINES as a module in a project. before the change , all worked . and the differenz between both is only about application''s environment, before is Ruby version 1.8.6 (i486-linux) RubyGems version 1.1.1 Rails version 2.0.2 Active Record version 2.0.2 Action Pack version 2.0.2

Hi all ! I''m having an issue and I can''t seem to make heads or tails of it. I am attempting to add an observer to a model object. I created app/models/greenback_transaction_observer.rb, inherited from AR::Observer, defined methods, registered in config/environment.rb, but things don''t work... So, I took a step back and put in the following code: class

Search doesn''t seem to be working, so forgive me if I''m covering old ground here, but I''m having a difficult time figuring out how to implement a "SUM()" function using Active record. Obviously, I could just create a query, but I''d rather make it part of my active record object. Basically I have an object called "Report <

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, I am new to Ruby and Rails, so I don''t know if this is my fault, but maybe this is a bug in Rails (I''m using Rails 3.0 beta) which should be reported. I have following search statement: [code]events = CalendarEvent.find :all, :conditions => { :target_date => begin_date..end_date }[/code] which produces following sqlite output: [code]SELECT

I have the following models: User, Registration, Event. User has_many Registration, Event has_many Registration, and Registration belongs_to User and Registration. So far, so good. There''s a registration deadline on a Event though, a few days before the Event occurs. So, I have this: class Registration < AR def before_create errors.add_to_base("Registration deadline has

I''m trying to create a separate class to do validation so that about 10 models can use the same date validation. I have tried to use the example from the agile book but it''s not working. Here''s what I have: app/models/date_callbacks.rb class DateCallbacks def before_validation(model) if model.start_date > Date.today model.errors.add(:start_date, "must

I have a decoupled form embedded in my pages ? a search box that has date fields ? and of course the search fields are not in my model. However, picking dates is a great use for the Dynarch calendar. It seems that by using the syntax: <%= render :partial => ?filter_box? %> In my view and... <%= dynarch_date_select ''filter_box'', ''begin_date'' %>

I have two problems. I have a comment that has_many uploads. Before saving the comment, I want to be sure that the upload(s) has passed validation, but I also need to validate in other ways. For example, I do not want to save the comment if there is no comment or upload. Or, I do not want to save the comment if the image has been uploaded previously (comparing md5s with past upload md5s

Hi, I needed to be able to add actions to be taken during the lifecycle of ActiveRecord object, but needed to configure it dynamically. Observers were not flexible enough and I ended up developing ArEvents, which lets you easily attach and detach event listeners, the events correspond to the active record callbacks. If you have an existing model, just include the ArEvents module:

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

Hello. I have a program that accesses a metadata (translation) table for column names as well as the ordering of columns for a specific model. Also in there is a collection of bool options such as column_visible_on_form, column_visible_on_screen_quicklist etc. The idea is that our customer can specify to a certain extent how their layout/user interface will appear. To accomplish this, I use

I have created a scaffold Admin/Radicals for doing CRUD. However, I''m not sure exactly where the scaffold uses the save() method. For a new entry, it creates form "radical" referencing method create(). The code for create() is as follows: def create @radical = Radical.new(params[:radical]) if @radical.save flash[:notice] = ''Radical was

I have the acts_as_ferret plugin installed. Everything searches great, but I would like to limit the results (i.e. by ''end_date'') and sort them (by ''end_date''). ''end_date'' is a valid column in my "posts" table. Here''s the code I have already: @posts = Post.find_by_contents(params[:query]) params[:query] comes from a form. I

I''m trying to create a paginated list that will take note of the "end_date" field in my table. This is what I have: @post_pages, @posts = paginate(:posts, :per_page => 10, :order_by => ''end_date'') in the controller. And for the view: <h1>Posts ending soon</h1> <ul><% for post in @posts do %> <strong>Post Title:

I abandoned ruby way for find_by_sql and still can''t get this... @myplacement = Placement.find_by_sql( "select * from placement where :intake_date >= beg_intake_date and :intake_date <= end_intake_date") just a simple date range...it''s killing me - If I knew how to load placement controller into irb, I could probably try out finds interactive mode... Thanks

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
