Rails - Apr 2010 - Is it possible to have a form without a submit tag in rails?

This is probably a stupid question but I am confused...

I see an example in the 3d Edition of Agile Dev with Rails (page 539)
where a simple calculator view, with two text boxes for numbers and a
dropdown for what operation to perform, does not mention a submit button
or gesture.

I don''t understand that. Yes, the form_tag does indicate an :action
=> ,
but what triggers that if there is no <%= submit_tag ''Save''
%>?

Thanks!

Pito

Browser dependent, but usually if you hit ENTER while in a text field  
it will submit the form.

Or perhaps that form''s submission is being triggered via javascript.

There may be chance of form without submit button ..
In your example might be form is submitting in script by using the 
javascript function submit() inside the script tag, when any of the 
field changed inside the form

<script>
$("#student_name").change(function(){
$("#sree").submit()
})

</script>
<form id=''sree''>
<%=text_field ''student'',''name''%>
</form>

Hi Phillip

There''s no javascript, but I think the default submit via ENTER must be
what was intended. I didn''t know about that. Thanks!

All that enter does is to hit the button by the keyboard instead of
the mouse, so that does not explain it.
Have you got the pdf of the book, if so then copy out the view and
post it here.  Or is the code downloadable from somewhere so that you
can get it and post it?
There is definitely a form on the page I presume?

Sure it does. Open up a test app and put this minimal form in a page:

<form action="/"><input/><input/></form>

Load the page, put focus on one of those fields and hit the enter key.

I tried it, nothing happens. (in FF)

Proving it *is* implementation-dependent -- the form submits in both
Safari and Chrome (on OS X, at least).

So it is not likely that the tutorial the OP is following is assuming
that this will work.

As far as I can tell that is precisely what the the tutorial the OP is 
following is assuming. I also have a copy of that book and the example 
form is exactly as presented by the OP. Two text fields and one select 
field with no submit button. There is no mention of JavaScript. The 
example form is illustrated in Safari, which would function, but 
probably would not work in FF.

So Yes, this is a bad example. The form should contain a submit button 
if you want it to work consistently in all browsers.
