Issues creating tables in mysql tests
Hello,
I''m a beginner, so any hints are appreciated; I''m still trying to find my
way around Rails code. For a bug I''ve found I need to create a table called
"values" so I added this:
create_table :values do |t|
t.integer :value
end
among the other table creations in
activerecord/test/cases/migration_test.rb. Is that ok? But then, when I run
the tests

Adding sortables dynamically
Hi all,
is there a way to define the containment option for a sortable so
that it is a class name instead of an id list?
I have a case very similar to the sortable lists demo, the only
difference is that I'm adding new list containers dinamically, so
either I need to redo the Sortable.create calls for all new elements
to include the newly added container, or having someway to have them

Question about sortables
Hi,
I''m trying to use sortables to sort table rows and move them between
different tables (yes, it''s actual tabular data ;). However, either I
don''t know how to use the tag property of Sortable.create properly, or
it''s only working for li''s. Since it''s probably the first option,
could someone post an example of sorting tr tags and move them

Uncomplete hiding on Firefox 1.5
Hi all,
I have observed the following on Firefox 1.5 (both on XP and OSX):
My page has some div containers that hold sortable ul. The div's also
contain links for showing/hiding the contained ul's. No matter which
effect I use to do the hiding and showing (Fade/Appear, SlideUp/Down,
BlindUp/Down) the hidden ul's don't hide completely, leaving a blank
'trace' behind.

I have built a select field that allows multiple options selected with
collection_select and "multiple"=>"multiple". How do I go about
receiving the values? If I use a variable name like collection[], it
complains that I can''t use @collection[] as the instance variable.

Multi-level drag and drop in scriptaculous?
I am trying to create a screen like Google''s personalized home pages or
start.com, i.e., with draggable sections, with the extra feature that
the child items under the parent headings could be dragged and dropped
from one parent heading to another.
I have set up nested droppable sortables (dropOnEmpty=true) but the
behavior is very inconsistent, i.e, parents do not become droppable

Too much recursion
Hey Guys,
I''ve just encountered this error in Firefox will I pulled the latest
scriptaculous rc into project. Sadly, I don''t have a linkable page for
you to look over at the point. My question is what is this error
exactly? My code before this never got it but now it does. My few
searches suggest it''s the browsers way of keeping infinite loops from
happening

DB Modelling the Rails way - Opinions??
Hi,
I''m trying to figure the most efficient way to model the following. I
can think of at least two ways to relate the tables but from a
client/server perspective! I''m wondering how to best (and
elegantly)relate them from an AR perspective.
A project has many people,
A person can work on many projects at any time,
A project has many roles,
A role is performed by a person,

naming convention for bridge tables.
I read somewhere that the correct naming of bridge tables is in alpha order.
For example. I have two tables:
houses, and colors.
If I want to create a bridge table to associate colors with houses, I would
name the table:
colors_houses
The associations work fine.
But, if I have a table named: track_houses.
Building a bridge table called: colors_track_houses, gives me model
associaton errors.

Concatenated key
Hi all,
I started playing a couple days ago with Rails and it find it very
interesting.
But I''m a bit stuck with making it work with a concatenated primary key.
I want to use my own names for the DB fields and I''m using SQL Server
2005.
My tables look roughly like this:

USR_ID VARCHAR(25) NOT NULL PRIMARY KEY,
USR_PASS VARCHAR(25)
