Hi all, I am having a lot of trouble to get the default value of text fields when they are generated by a partial from a collection. I have been on this for a whole week and I didnt find a single exemple on the internet of someone using a partial that generate text field with a default value. I cant believe that I am the only one having this problem. Anyone has an exemple they can show me?

I have a question concerning where to use the synchronize function. The point of it is to put all of the code blacks passed to this function in a queue. This make sure that code gets ran one at a time. This is required when doing any kind of database activity in backgrondrb and multiple threads. Otherwise I lose the connection to my database. So here is my question: Do I need to do: @lock =

Hey all, I''m rather new to Ruby and Rails (and not great with SQL), but I''m developing a ride sharing app and would like to be able to sort on something I don''t have stored. I have users, events, and rides, each of which has a zip code. Events have_many rides, and rides belong_to events. When an event is selected, I''d like to be able to show a list of

I know - I like to futz. I''m thinking of changing the way I pass optional arguments. This is from EventLog: # Write an event to the event log # Current way el.report_event( "source" => "foo", "category" => 0x2, "event_id" => 0x3, "data" => "Warning! Danger Will Robinson!", "type"

Hi, I''ve got EventLog#write and EventLog.add_event_source methods done. Well, I *think* they''re done, but I can''t get the data (text) to work properly, and I''m not sure if it''s a bug in my .mc file, the add_event_source method, the write method, or just a goof in my test file. The source, category and event id seem to be ok. However, the

This is a real mystery to me. I have an instance variable in a partial that only gives its value inside a hidden_field_tag. If I try to use the variable anywhere else in the partial, i either get nil or an undefined error. The goal is to use the value of @event.id outside of hidden_field_tag. Here''s what works: <%= hidden_field_tag ''id'', @event && @event.id,

We don't really expect to have too many events in the queue. If there are, then the algorithm we use isn't appropriate. Add a warning when the queue gets very long, as it's an indication of something having gone wrong.

I''ve created the following associations using :through: class Person < ActiveRecord::Base has_many :attendees, :dependent => :destroy has_many :events, :through => :attendees, :uniq => true end class Event < ActiveRecord::Base has_many :attendees, :dependent => :destroy has_many :people, :through => :attendees, :uniq => true

I''m working on a fairly complex join query and could use a bit of advice from more expert users of ActiveRecord. I have an events table with quite a lot of data, with has_many relations to categories, age_groups, and event_images. In my first naive implementation, each event had a date, so to load all upcoming events efficiently, I''d do: Event.find(:all,

Hi I''d like to know how to add default text text area using the function text_area. I ''ve tried using value = "....." to do this but with no luck. Could some one please answer my simple question? Thanks. Dan. -- Posted via http://www.ruby-forum.com/.

Forgive the term global if that''s not applicable in rails (i come from a php background) I have a browse controller with a couple of different methods def method1 @properties = Property.find_all #other stuff for that method end def method2 @properties = Property.find_all #other stuff for that method end def method3 @properties = Property.find_all #other stuff for that method end I

Hello, I''m having a problem utilizing the find_all method with a value from a form. I keep getting the following error: Mysql::Error: #42S22Unknown column ''category_id11'' in ''where clause'': SELECT * FROM items WHERE (category_id11) The controller seems to be getting the correct data, but my key and value seem to be mashed together(it''s

How does one properly get find_all to grab the data from the DB table ordered by a specific column? For example: @anglers = Angler.find_all This code gets all the angler records and they are sorted in order of the id field which is of course set as a primary key in the DB (mysql). I''d really like to pull the data from the DB sorted in the order of another field, for example

I have a pretty strange problem. Here is basically what I have to demonstrate my problem: class Event < ActiveRecord::Base def after_create AnotherClass.find_event(id) end end class AnotherClass < ActiveRecord::Base def self.find_event(event_id) e = Event.find event_id end end Here is the catch 22 and it''s quite annoying. Basically ActiveRecord puts to whole save

I am implemented a simple project management application. Each project has various events, and each event can be a different type. Some event information is common, such as name, start date, close date, and comments. I have a projects table which has_many events. My plan is to have several sub-event tables, like event_get_access which will contain an event_id field to link it to table events as
