If I make a change to a database table, how do I recreate the model to reflect the change? -- Posted via http://www.ruby-forum.com/.

I can''t find any documentation on the ''status'' magic field. It''s listed on the MagicNumbers wiki entry, but not explained < http://wiki.rubyonrails.org/rails/pages/MagicFieldNames>. Is it reserved for later use? Thanks, Doug -------------- next part -------------- An HTML attachment was scrubbed... URL:

Can someone point me to a reference or tutorial that shows how to map foreign key relationships in the model? For example given: Users id name email Posts id user_id title How do I associate user_id with users.id in the Post and User models? has_many and belongs_to don''t seem to do it. -- Posted via http://www.ruby-forum.com/.

I''m testing the relation between two of my models: MessageThread (parent), which has_many Message (children).

This has me scratching my head: a Person has many Things a Person has many Collections a Collection has many Things ...Things in a Collection are ordered ...Things in a Collection can be related to (created by) any User ...a collection has additional attributes, such as a name etc I am confused about habtm in rails (especially when using acts_as_habtm_list) vs. going the :through route.

Hi ! There must be something I don''t understand clearly in acts_as_list I have a list of gallery entries (images + text), model is GalleryEntry. I have a field in_exhibition (boolean) I want the list to be sorted with a scope on in_exhibition : from 1 to N for every record having in_exhibition = false and 1 to N for every record having in_exhibition = true When I use acts_as_list

I''d like to be able to use a has_many :through association and treat the associations as a list but I''m getting this error when I try an use an acts_as_list method: NoMethodError: undefined method `move_to_bottom'' I''m using edge rails r6786. Here are my domain rules: Activities are things students can do. Units consists of a sequenced list of

I have a model "Childmodel" that belongs_to two other models "Parent1" and "Parent2". "Parent1" "has_many :childmodels, :order => :positionp1" and "Parent2" "has_many :childmodels, :order => :positionp2". i.e. The child is independently positioned within each of its parents. This works fine and gets me the useful

For example I have table Questions. With fields id, text, and test_id. test_id is not being displayed in my view. I am hoping this means Rails has picked up that it is an id for another model. If so, then how do I utilize that? If not, then do I need to avoid ''id'' in any field names other than the main id field? Thanks! -- Posted via http://www.ruby-forum.com/.

The new pragmatic Rails Cookbook has a drag and drop sorting recipe. Does anyone know if this works with 1.0? I''ve followed the recipe (i think), and I can drag but when I drop everything goes back the way it was. It seems that the sort logic doesn''t get invoked. I put this code in my view: <%= sortable_element ''task-list'' , :url => {

I am trying out ROR for the first time[1], and have much PHP poisoning to overcome in my mental baggage. That said, I was delighted to find that I could make a link from a "show" page to the next record in the database by simply adding @next_page = Content.find(params["id"].next) to my content_controller.rb and then constructing a link to it within my show.rhtml. The

DB field names: If I have a table that references 2 or more separate users from my users table, is there a recommended naming convention for this situation? In my case, I have 3 users associated with a record in my projects table: requester_user_id created_by updated_by I could name one of them "user_id", and then projects.user would work I guess, but wouldn''t work

First, BRAVO for this wonderful plugin: has_many_polymorphs ! Now my problem: 4 models : Collection, Page, Fragment, Belonging (which is the join table): 1 class Collection < ActiveRecord::Base 2 has_many_polymorphs :elements, 3 :through => :belongings, 4 :from => [:pages, :fragments, :collections], 5 :as => :collector, 6 :parent_order =>

I''m working on some schema for a new project that we''ll be doing in rails (our first rails project!). A recurring structure we are seeing is the desire to define an ordering any way we wish, so ''acts_as_list'' comes to the rescue. But, the ''position'' column seems to need to belong in the join table to make sense. For example, we have

Hi there- I''m a newbie to this board, RoR, and web development in general. So please forgive me if this is in the wrong place or if the solution is really simple... I''m trying to conceptualize the relationships between a series of models for a page creation function. What I''d like is to have a Content Page which consists of a series of Content Blocks. The Content

Here''s what I''m trying to do: class Model < AR::Base acts_as_list :scope => [:key_one_id, :key_two_id, :key_three_id] end with the idea being that there are these three references from this table (one of them being optional) that define the list.
