Hi there, I'm using Open Flash Chart to create a pie chart of user's
categorized spending. It currently includes only categories that I
have in my Category model, but does not include "uncategorized"
entries which have no association in the entry_categories table.
I'd like to include those entries that are not categorized as well in
my grouping so that I can display them in the pie chart as
"uncategorized." How would i do that? Below is the SQL that
successfully grabs categorized entries. How would i retrieve and
group uncategorized entries as part of this query?
@entries = Entry.find_by_sql ["SELECT sum(entries.price) AS
categories.name AS category_name, categories.color AS category_color
FROM entries, categories, entry_categories
WHERE entries.user_id = ? AND entries.id =
entry_categories.entry_id and entry_categories.category_id =
GROUP BY categories.id", current_user.id]
Thanks in advance.
