...hose empty House records in the database is a lot of waste. I''ve tried variations on the below code, each of which has failed to work. It *seemed* to work, but it doesn''t persist to the database properly: class Person < ActiveRecord::Base has_one :house def house if !read_attribute(:house) h = House.new h.save write_attribute(:house, h) end read_attribute(:house) end end Can anyone tell me the proper way to accomplish this behavior? Thanks! John

Hi all! I have come into a strange issue in Rails that I am hoping someone can shed some light. To make a very long story short, I have been researching how to override ActiveRecord::Base#read_attribute and write_attribute to perform security checks at the model level (influenced by the ModelSecurity generator). Shortly after implementing some code to check this behavior, I began to see undefined behavior from rails. The first request to read an attribute would be denied correctly, how...

Hi! I''m a very-very new Ruby-on-Rails user even if I have some experience with other Languages (mostly PHP, so this is my first real object-oriented language) My problem, newbie-ish as it is, is the following: I have a model, Article, that returns Articles from the DB. Now, when a certain field of the model (the intro text) contains no data, I want to fill it with a truncated

There are definitely some files with some weird names- in an ssh session they don't even have regular characters. e.g -rw-rw---- 1 xxx xxx 114985112 Oct 31 14:39 ▒^t Not sure if that is related to problems though.

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? Example: I have a field phone_number which I always want to preformat using the number_to_phone() helper.... Any help is appriciated. Thanks! -- Posted via http://www.ruby-forum.com/.

Hi. I have two types of fields in my database, e.g. "name" and "name_ru". First one is a user''s name in english and the second one is in russian. I want to intercept calls like "c.name" and add "_ru" to it if current language is russian (I have my own Locale class like n Globalize). So I want such thing: -- Locale.set("en-US") c.name

All, I''m finally doing my first real form in Rails - the model object that I''m entering information for has 8 validations so far. If I type in good values for all the fields but one, I get the pretty validation, and the nice field highlighting, but all of the fields are cleared, forcing me to retype all of that info. That is a big drag. Is there a standard way to get the

Hi all, here is the challenge: I have this validation method, that basically prevents an object which billed = true to be updated: def before_update if read_attribute(:billed) errors.add_to_base(''This service has already been billed for'') end !read_attribute(:billed) end The above code does not work in case I do something like: object = Model.find(:first) object.billed = true object.save because in my before_update filter I a...

ZFS introduces a new and incompatible ACL interface into Solaris and this seems to be not yet fully completed in addition to the fact that is causes a lot of problems for software that needs to be compatible with Solaris-2.5 like star. Proof for incompatibility: create a file on UFS and set an ACL for this file. Use Sun tar cpf out file to archive this file. Unpack this archive file on ZFS

When a column in a database table is actual data, rather than an fkey to another table, I can override the automatic accessor by just doing the following: def field_name # do something here read_attribute(field_name) end This does not seem to work for me if the field is an fkey, say user_id, linking to another table. I''ve made this work by aliasing the accessor like this: alias old_field_name field_name def field_name #do something old_field_name end This works, but is there a buil...
