find for multiple tables & updates

rubyonrails-talk

Would like to use ActiveRecord find for multiple table lookups with sort order on parent table.

Example: Item table belongs to Category and Section tables. Category and Section tables have only 2 attributes: id, text field (category and section). Item has many attributes in addition to category_id & section_id.

    1. Sort items by category or section TEXT field not the id fields.     2. Be able to update the Item attributes but not category or section.

A. Use find_by_sql? B. Use find and ":include" option. C. Use ":from" option to refer to an SQL view of the joined tables?      i. Then switch to an updatable Item form? D. Use some other approach?

Best regards,

Go with B.

Items.find(:all, :include=>[:category, :section], :order=>"categories.name, sections.name, items.name")

The key is the :order option.

Works like a charm! A little tweaking and the rails magic delights once again.

Rails is extraordinarily amazing. (Once you know how it works. :slight_smile:

If only the documentation and examples were a bit more illuminating. Sigh.

Many thanks, Andy.
