Ruby on Rails: How to have multiple submit buttons going to different methods (maybe with with_action?)

Question

So..

<%= submit_tag 'Save', :name => 'save' %>
<%= submit_tag 'Save to Library', :name => 'library' %>

then in my controller:

with_action do |a|
    a.save do

    end

    a.library do

    end
end

the problem is that only one of the actions is getting invoked... the same one for both submit_tags... any idea why?

or how I can get two buttons to submit a form to two different methods?

Solution

The submit button name attribute is passed to the controller as params[:commit]. So in your case:

if params[:commit] == "save"
end

I did a puts params, and there isn't a :commit key in the params hash... =\

What does the params hash contain?

[NullVoxPopuli]

When I use :name there is no :commit. wehn i don't use :name, the :commit is the text of the button

[Tomas Markauskas]

Then use the name instead of :commit.

Works for me. Been looking all over for the answer to this trick. Thanks!
