and wanting to display the categories in a drop down list. Below is the error I
get. Any suggestion on how I can fix this.
undefined method `name'' for #<Category:0x3652448>
9: <select name="product[category_id]">
10: <% @categories.each do |category| %>

What a jerk. Who is his employer? I think we should start a fund to boycott
them. If he works for a software company, the quality of their product must
suffer from the contributions of someone as "enterprisey" as James
McGovern.
The title of the posting is conciliatory

isn''t at all, in fact he borders on being a troll. Way to contradict
yourself again James.

A web server is a great technology to communicate applications. It is standard,
and everyone know how to work with web services.
A good example for a web service:
In my company, we have a lot of web applications, for clients and for workers.
All the logins, are local to a web application. So if you log into web
application A, and then you want to go to web application B, you have to put
another user and another password, although you are the same client, big
problem.
So I''m implementing a solution, a login server for all those webs, so I
can store all the logins in the login server, specify in that server what web
applications they can access, metadata associated to each login, etc.
The web applications in the company were programmed mostly in PHP, and there are
some web applications in perl, and some web applications in ROR. So I''m
doing all the login for the login server in ruby on rails, and I''m
implementing a web service to communicate and give an standard API to the others
applications, criptography, etc; and the changes that they have to implement in
their current web applications are very little. And even better, we can now
provide access to the web service to our provideers, so they can use our login
server and we can integrate with our provideers.

Yes, that''s what a web service would be good for.
A webservice is essentially a way for applications to get data from other
applications using HTTP.

Ahhhhhhh, since it''s not a partial, no underscore. Well, no. I must
be doing something wrong still. Actual code:
<%= link_to_remote( image_tag("capsule_public.gif", :size =>
"72x16"),
:url => { :action => ''shared/script_status_cycle'', :id
=> @member.id })
Should go to "shared/_script_status.cycle.rjs," I would think. Or
"shared/script_cycle_rjs." Neither seem to work.
I get this error:
ActionController::UnknownAction (No action responded to
shared/script_status_cycle), which tells me that it''s not actually the
RJS that is the problem, it''s the action. So I think my approach must
be wrong.
I need to go to the "script_status_cycle" method in my controller,
then move to a shared component rather than one in the normal place.
I think I''m over-thinking this, or missing something obvious.
To clarify after all that, I have an rjs template I want to use in 3
controllers. How do I accomplish that without having to keep 3 copies of the
template?
Thanks,
-Ron

Unfortunately, James represents the mindsets of many corporate decision makers
out there. While he is trollish, he does have a point. A lot of decisions made
by C-level folk require a Gartner and Forrester report before it ends up as part
of the picture. Look how long it has taken for Linux to become accepted as an
"enterprise"
solution.
Rails will eventually cross that hump, but it''ll be completely
mainstream by then. In the meantime, smaller, more forward thinking companies
can take advantage of the agile development that we enjoy from RoR.

Whenever I change a view template or layout in my application, I have to restart
Webrick for the change to take effect.
I have tried everything i can think of. I am not in production mode (not passing
the "-e production" argument to webrick when I start it,
environment.rb has the production line commented out).
I have cleared caches on all of my web browsers, and gone around and tested this
on all of the computers in my office, but none of them will see the new output
until Webrick has been restarted. Editing controllers is fine, the new code
takes effect right away. But with views, I am dead in the water until I restart
the server. Others don''t seem to have this issue, any ideas?
My server is running OpenSUSE Linux.

what you''re talking about is EXACTLY what i would need. is the
development of something like this very hard? are there any pointers you
could give or places to start out for something like this?
your help would be greatly appreciated in any way you can.

PLEASE help me - this is making me insane.
Can anyone suggest any reasons for this behavior? It occured previously,
then went away and is now back.
In Task.rb (where task is an active record subclass)
def clear_schedule
puts "clearing schedule for task"
scheduled_end_date= nil #reset the
scheduled end date
save
halt. #this makes
execution stop with an error.
end
This is the console output this produces:
clearing schedule for task
127.0.0.1 - - [28/Apr/2006:13:44:01 Eastern Daylight Time] "POST
/tasks/update/1
06 HTTP/1.1" 500 10736
http://localhost:3000/tasks/edit/106 -> /tasks/update/106
When I query the db, scheduled_end_date is still set to a valid date, even
though in the model I set it to nil, called save and then stopped. There
were no exceptions other than this:
undefined local variable or method `halt'' for #<Task:0x3a23328>
I sometimes have the opposite problem in a related piece of code for this
same object/column (I set it to a real value, save it, retrieve the object
from the database in the very next line of code. When I check the value
it''s
nil.)
Can someone tell me what the expected behavior is within a transaction
versus outside of a transaction? The behavior seems unpredictable in both
situations but I''m not sure. I assumed that if I was inside a
transaction
that I would still see the new value. All of this occurs within a single
http request so I assumed that all the data access was on the same
connection.
Anyway, I''m stumped and resolving this is critical to my project.
Please
help if you can.
