[Rails] Collecting data from forms

Hi,

I?m having some problems collecting the content of some forms.


This is whats in list.rhtml:

<%= form_tag :action => ''send_message'' %>
From:
<%= text_field	''message'', ''from''%>
<br>Message:
<%= text_area	''message'', ''text'', :rows
=> 6 %>

<tr>
   <td></td>
   <td><input type="submit" value=" Send the message!
" /></td>
</tr>




the controller:

def send_message
   from = (params[:from])
   message = (params[:message])
   puts "From field: = #{from}"
   puts "Message field = #{message}"

   system("echo #{from} > /tmp/echo-say")
   system("echo #{message} >> /tmp/echo-say")
end


How can I transform the content from the form to a variable so that I  
can use it in a system() command ?


Best regards,
Martin Stabenfeldt

from = (params[:message][:from])

Tried to do a
   puts "the message is from #{from}"
but is quiet.


What is the right way to print the content?

This is how the controller looks like now:

def send_message
   from = (params[:message][:from])
   text = (params[:message][:text])

   puts "from:	#{from}"				# says nothing.
   puts "message: #{message}" 		# empty here as well.

   system("echo #{from} > /tmp/echo-say")	# ..and here.

end

It would really save my day, if someone could show me how to do this  
correctly!

[Rails] Re: Collecting data from forms

Hi Martin,

I''m still real new to RoR so take this with a grain of salt...

In general, the result of the processing that takes place in a controller
action is rendered (i.e., output) in a view with the same name as the
action.  You''re trying to produce output in the controller.  I
don''t know
enough to say for sure that that won''t work.  But if I were sitting in
the
next cubicle and you hollered over  "hey bill, my
''send_message'' action
isn''t rendering like I expect it to",  I''d ask...
"what does your
''send_message'' view look like?"

HTH,
Bill

def send_message
   from = (params[:message][:from])
   text = (params[:message][:text])

   puts "from: #{from}" # says nothing.
   puts "message: #{message}" # empty here as well.

   system("echo #{from} > /tmp/echo-say") # ..and here.

end
