I have a very simple form that looks allows an input for an error code
and then give the show page from the scaffolding if the error code is
in the database and a notification on the list page, again from the
scaffolding if not.
Here’s the form:
find.rhtml
Find error
<%= start_form_tag :action => 'search'%>Code
<%= text_field 'message', 'code' %>
<%= link_to ‘Back’, :action => ‘list’ %>
Here’s the method, search in the controller
def search
code=params[:message][“code”]
@message = Message.find_by_code(code)
if @message.nil?
#render :action => ‘find’
flash[:notice] = “Code #{code} not found!\n Please choose a
code from this list”
flash[:error] = ‘Boom’
redirect_to :action => ‘list’
else
redirect_to :action => ‘show’, :id => @message
end
end
It works except for the fact that flash[:error] does not display and
in fact if I try :error for the first flash, it will not display.
Aside from this problem is their a better way to do this. I have the
agile book and googled quite a bit to finally find how to pass
non-database elements from a form to the controller, but I’ve lost the
link. I’m new to web apps so I don’t know what the accepted practice
is for something like this so any helpful advise or criticism is
appreciated.

The deep fascination of myths is that they speak directly to deeper
levels of our nature and to the subconscious, and give the profound
assurance that we are each, in essence, deathless and immortal sparks
of Divinity on the long evolutionary journey into higher consciousness.
