Testing and assigning with regexp's

I’m new to Ruby, and in a little program I’m writing, I have code like
this:

str = ‘’
if /something/.match(str)
str = /something/.match(str)[1]
end

Is there a more elegant way to do this?

Mike S.

str = $& if str =~ /something/

Although, running this when str == ‘’ is pretty useless.

A useful pattern is:
str = $1 if /(something)/ =~ str

or without the capture:
str = $& if /something/ =~ str

Hi,
I’m trying to pass an object from the View to the controller as a
hidden field.

Two quick questions:
For a hidden field, how do I pass a complete object to the controller?
For example, I have an object of type Issue, what should the second
argument be in the
following:

<%= hidden_field(“issue”, ?, “value” => @issue) %>

Secondly, how would I access this object in the controller?

Any help would be appreciated.

Thanks,
Anupam.

Firstly:

Please don’t start a new topic by hitting “Reply” in your mail
application. This messes with the threaded view used by a significant
number of users, and you might not get answers.

Secondly:
The Rails groups can help you more with this question, I guess:

But what about people, who do not want to use ugly webforums or
even-more-ugly mailing lists which flood their mailboxes?

Do you know about a newsgroup where one can discuss rails topics?

What do you think is this? If you don’t want to use the sources of
information that are available to you, you are out of luck, harsh as it
may sound.

I really do not understand, what you want to do. Which sense does it
make,
to pass an entire object into a form and back to the controller,
when you do not want to manipulate it in the form? You could store it in
the session instead or fetch it from the database, when it lives there
after you got the form posted back.

From your posting one can assume, that you do not know nothing about
rails
at all, then I would recommend to search http://www.rubyonrails.org/ for
a
tutorial and http://api.rubyonrails.org/ for the APIs documentation or
read a book like “Agile Web D. with Rails” from Dave
Thomas and David Heinemeier H…

If you want more help here, please describe your problem more detailed.

At the bottom of the Google G. Page it give you the address for

If you just want to search then just search. You don’t have to have a
google account, although it isn’t hard to get one.

The very first entry “general list” is not a news group but a google

way to use them in my newsreader via nntp?

You will need to pass the id and then get the object from the db using
the
id in the controller.

Secondly - ruby is the language in which rails is developed. This list
is
for the language, which is used for more than just rails, so posting
rails
questions to this list is annoying to people who have nothing to do with
rails.

For rails related questions join the rails mailing list:

And on my end it is a usenet newsgroup. But as far as I know, even
google
makes a difference between usenet and mailinglists or google groups
though
they have built various gateways into usenet. And usenet people
definitly
do.

In general, you want to ask Rails questions in the Rails mailinglist, as
your chances of getting an answer are higher by an order of magnitude.

Yes. But I am searching for a usenet newsgroup for rails because without
a
comfortable newsreader I would not read it anyway. But you are probably
the wrong person to ask.

The very first entry “general list” is not a news group but a google
group, for which I need a google account - or am I wrong and there is a

I have no clue. I use the email feature Google G. provides. You’d be
better of to seek for that answer in the Google G. support.

Again: I am not using google at all. But to get a clue, what I am
talking
about: http://en.wikipedia.org/wiki/Usenet

Thanks Igor for you useful response. I would try the Rails community.
I didn’t realize this is a Ruby ONLY list.

In that vein,
str.gsub!(/\A.(something).\z/, ‘\1’)
