New to RoR. Using text input as a parameter in query.

I'm new to RoR and I am trying to figure out how to use user input from
a text field as a parameter in a query. I know this is probably simple
but I have been messing around with it for a while and can't figuire it
out.

The controller has this method:
def search
@events = Event.find(:all, :order => 'date DESC',
:conditions => ['title=?',titleinput])

respond_to do |format|
format.html
format.xml { render :xml => @events }
end
end

and the view:
<form action='/events/search' method='post'>
<p>
<b>Title</b></br>
<input id='event_title' name='titleinput' size='30' type='text'
value=''/>
<input type='submit' value='Search'/>
</p>
</form>

I know this is probably completely wrong but I couldn't figure out how
to use the variable from the form in the query in the controller.

Thanks for any help.
Ben

In Rails, variables in forms are stored in the params hash so, in your
case, to get the value of titleinput you would do params[:titleinput].
This would change your controller's search method to the following:

def search
@events = Event.find(:all, :order => 'date DESC',
:conditions => ['title=?', params[:titleinput]])

respond_to do |format|
format.html
format.xml { render :xml => @events }
end
end

In general, Rails questions are better asked on the Rails mailing list.

Hi, since RoR is a framework based on Ruby is better you ask this kind of=20
questions in a RoR maillist. Note that RoR adds its own "magic" to Ruby ;)
