Rails - Apr 2006 - Multiple actions from one form - possible?

Hello *

Obviously the rhtml below does not work, but it should be apparent what 
I try to achieve - I would like to give the user the choice to submit a 
form either to action1 or action2 but I cannot figure out how?! It would 
be great if someone could give some assistance.

Thanks a lot, Alex

<%= start_form_tag :action1 => ''save'', :action2 =>
''saveandsend'', :id =>
@letter %>
	<%= submit_tag ''Save'', action1  %>
	<%= submit_tag ''Send'', action2 ''%>
  <%= render :partial => ''form'' %>
<%= end_form_tag %>

you probably have 2 methods like in your controller

def save
end

def saveandsend
end

You may need to define 2 views like save.rhml and saveandsend.rhtml, 
instead of  just one view as you stated.

Also, a form can only have one action, it is not a RoR rule, but a HTML 
rule.

Hello Liang, hello *

Thanks for the reply. Is there maybe another way and use in the view:

<button name="save">
<button name="send">

and then use

if params[:save]
else if params [:send]
end

in the controller? The problem I encounter here is that the <button....> 
is just a funny little button and not a real button (with name....like 
the ''Submit'' just below) which I would require....I guess this
is an
HTML issue. What would you suggest?

Thanks, Alex

I offer this, not as the best possible solution but as the one I came
up with when trying to do the same thing: I used one helper tag and
one plain input/submit tag, like this:

<p><input name="final" type="submit"
value="Submit (final
version)"/></p>
<p><%= submit_tag "Save and finish later" %></p>

And then in the controller I checked whether or not params[:final] was
set.

I couldn''t come up with a more homogenous way, but maybe someone will
enlighten us.

You need to dynamically change the action for the form using JavaScript. 
I''d write a helper function or two:

<script>
   function submitActionOne() {
     var act = ''<%=url_for(:action => "action_one", :id
=> @letter )%>'';
     $(''myform'').action = act;
     $(''myform'').submit();
   }

   function submitActionTwo() {
     var act = ''<%=url_for(:action => "action_two", :id
=> @letter )%>'';
     $(''myform'').action = act;
     $(''myform'').submit();
   }
</script>

<%= start_form_tag({ }, { :id => "myform" })%>
    <%= button_to_function("Submit One",
"submitActionOne()") %>
    <%= button_to_function("Submit Two",
"submitActionTwo()") %>
<%= end_form_tag %>

inside your button tags put something like
onclick=$(''my_form_id.submit()
This should make the two buttons act as submit buttons

Hello Alex,

I learned how to do this at
http://tr.openmonkey.com/articles/2006/01/16/multiple-ajax-submit-buttons-in-a-rails-form

And here is a stripped-down version of what I did to
get action variations driven by which button is selected.
Basically, users are able to change the state or remove items in
some table rows (not shown). One column had checkboxes to
indicated which rows are to be affected).


<%= start_form_tag :action => ''update_list'' %>
....
    <input id="update_button_Enable Selected"
name="update_button[Enable
Selected]" type="hidden" />
    <button name="_update_button"  type="submit"
value="Enable Selected"
onclick="">
        Enable Selected
    </button>

      <button name="_update_button" type="submit"
value="Disable
Selected" onclick="Form.getInputs(this.form, null, 
''update_button'')[0].value = ''Disable
Selected">
        Disable Selected
    </button>

      <button name="_update_button" type="submit"
value="Remove
Selected" onclick="Form.getInputs(this.form, null, 
''update_button'')[0].value = ''Remove
Selected">
        Remove Selected
    </button>
  </div>
....
<%= end_form_tag %>


In the controller ....

  def update_list
  ....
  ....
      case params[:_update_button]
        when "Enable Selected": enablement = true
        when "Disable Selected": enablement = false
        when "Remove Selected":
          # do the remove thing
        else
          flash[:notice] = "That button is not hooked up properly."
      end
  ....
  ....
  end

Alternatively, a simple solution is to name all of the action buttons 
the same but set the value attribute to distinguishing values.  So, in 
the rhtml file you would have:


<form action="../item/item_manage" method="POST">
<input id="Add" name="submit_action"
type="submit" value="Add">
<input id="Delete" name="submit_action"
type="submit" value="Delete">
</form>

In the item_controller.rb file then you can access the parameter 
submit_action and take the appropriate action

@action=@params[''submit_action'']

if (@action == ''Add'') then
...blah, blah
else
...blah, blah
end

Soroe.

Does this actually work ? It''s definitely not working on my
application.

it works fine for me.

Can u specify the error u get???

Can u check ur development log once how it passes the parameters??

Also try out assigning like this...

@action = params[:submit_action].strip

Regards.

Not that I have tested this, but....

I suspect the "submit_action" values are clobbering each other when
parsed.

Try putting them in two different forms, and I am not sure if that name
will work.

<form action="../item/item_manage" method="POST">
  <input id="Add" name="submit[action]"
type="submit" value="Add">
</form>
<form action="../item/item_manage" method="POST">
  <input id="Delete" name="submit[action]"
type="submit"
value="Delete">
</form>

I find it easiest to specify unique names for each submit button. You 
avoid name collisions this way, plus, the only submit name/value that 
gets posted is the one that is clicked.

----
View
----
<%= start_form_tag %>
<%= submit_tag ''Add'',   :name =>
''add_button'' %>
<%= submit_tag ''Delete, :name =>
''delete_button'' %>
<%= end_form_tag %>

----------
Controller
----------
if !params[:add_button].nil?
  ...
elsif !params[:delete_button].nil?
  ...
else
  ...
end
