Hi All, I''ve tried to do my searches, but can''t find reference to this anywhere - My question is about ActiveRecord inserts and IDs. I have a join table that both the models of the source tables join with "has_and_belongs_to_many". It seems like ActiveRecord is setting the "id" field for the join table- This should be an auto_increment and

Hi All, Probably this has been asked numerous times, I apologize already! Can somebody point me to a good tutorial on how Rails works with relations? I know about database design and normalization, I also know about programming in general (and OOP for that matter). Only thing I can say is that I''m following the "Four days on Rails" tutorial by John McCreesh. He writes

I have a project, it has members. I have the data modeled, the ActiveRecord setup but I''m running into a block as how to accomplish this in a view. I would like if when the Project is being edited to present a list of all users, and then have a checkbox beside each name. Those selected would be a member, those who are not, obviously would not be. I am, however, not closed to

I''m writing a simple CMS where every item ("listing") HABTM categories and subcategories (which themselves belong_to a category). What I''m trying to do now is create a UI effect for listing creation: when you go to create a listing, only the possible categories will be shown, but when you select a category a set of new categories will be displayed like so: Lions

Hi everyone, I''m currently finishing the planning phase of a small project I want to create. I read a bunch of tutorials about ActiveRecord and the different way to link your "tables" with belongs_to, has_many, has_and_belong_..., etc... However I''m stillnot sure if what I''m trying to do will work *well* with ActiveRecord. So enough talk,

I''m working on a simple CMS. The main data type are "listings" a listing habtm (has_and_belongs_to_many) categories and subcategories. Subcategories belong_to categories. Subcategories are basically the same as categories, but they are treated differently in a few situations. The problem is, I can''t seem to write the view/controller/model code that allows me to

I''ve got a menu in which I have all of my categories as links. Each category also has subcategories. I want to set it up so when you mouse over the category the subcategories will pop up (to the right of the main list, but that''s just CSS). This is what I have so far: <% for category in @categories %> <a href="#"

Hey all, Here''s my situation: I have a pair of controllers with associated models (called Services and Testimonials) that are quite similar. Because their CRUD behavior is executed via AJAX, the "templates" for the actions are all short .rjs files. Now, because of the similarity of the models, most of the templates are exactly the same, with only the object names changed. That

Because of the amount of users, I would like to set up my ACL's based on groups, rather than individual user accounts. I have successfully joined my samba box to our windows domain (2k).

Something that looks like this: [ ] - [ ] - [ ] ext: [ ] Then when you submit it it''s combined into one string in the database.
