Best way to propogate model rules to controller?
Hey everybody,
I''ve got a model that represents kind of a turn-based games. Certain
actions can only be made unders certain conditions. For simplicity,
we''ll say that the only condition for a particular action is that the
weekday be Tuesday.
def add_vote
raise ''You cannot vote today'' unless Date.today.wday == 2

end

Design Decisions
Hi All,
I am doing some research on how people start with their Rails app.
What design decisions are made and how is it build.
For example:
- do you use scaffolding and go from there? Or do you create everything
from scratch?
- are you using multiple controllers? Or do you put everything in one?
- do you use migrate?
- how do you use migrate? Do you call migrate your self or do you use

Merging two heavily referenced records into one
Here''s the situation: I have a "people" table whose "id" column serves
as a foreign key to several other tables (authorships, editorships,
members, users, etc.). Every now and then I will find two distinct
records in the "people" table that represent the same human being. They
generally differ by small differences in spelling but should really be

convert rails object to javascript variables
Am i a total idiot to try and parse out a rails object for javascript
in this way?
<%
for i in interface_items[0].attributes
%>
var <%= i[0] %> = "<%=h( i[1] )%>"
<%
end
%>
Am I missing something really obvious?
Thanks,
Mark

AJAX on Mobile Internet Explorer

I try to get AJAX running on a mobile Windows Mobile 5.0 based device

or are there any hints, documentation on the net?

Find by time?
I''m trying to find events created after an initial date. I''m sure it''s

Coding conventions (mostly AR)
I have the following tables: Users, Clients, Roles, Assignments(user_id,
role_id, client_id) and Rights(controller, action).
First of all, I''d like to know if hooking things up this way makes any
sense. Could perhaps add a second join table between assignments and roles,
but not sure that would add any value.
What i''m really wondering about, though - is how to do things the

Neat style trick
Not terribly exciting, but I was happy to think of it.
I needed a div with a fixed height that could vary depending on page
content.
So I did this:
<div class="listcntnr" style="height: <%= @users.size / 2 * 125%>px">
Whee!

AR many-many join tables - can they have created_on, updated_on ?
Hello all,
I''m creating a many-many join table between ''homes'' and ''users''. Can it

CREATE homes_users (
home_id int not null,
user_id int not null,
created_on datetime null,
updated_on datetime null
)
Thanks for your advice!

What is the cleanest way to load a div via AJAX when the page loads - no

How to use ssh -i with a key from ssh-agent rather than from a file?
Hi,
I have a VM with a git repository whose origin is on
github. I have several keys known to github, so I needed
to set git's core.sshcommand config parameter in the
repository to something like this:
ssh -i ~/.ssh/id_ed25519_github2
But it meant that I needed to copy that key to the VM.
The same key is available via my forwarded ssh-agent
connection. Is it possible to tell ssh to use
