Rails - Mar 2013 - Link_to if POST needed is a a hard nut to crack

So, I''m pretty much a beginner, so I would appreciate some help with
this
issue.

So, I have link_to helper (yes, I know that button_to is much easer, but 
for the needs of application it should be link_to), which should POST 
something in database without rederecting to any pages.

<div class = ''source>
<%= link_to(result_array[k], :controller =>''tests'', 
:action => ''add_key'',
:method => :post, :keyword => result_array[k], :position=>k, :remote 
=>true) + result_array[k+1]%>
</div>


add_key method in tests_controller.rb:

  def add_key
   @test=Test.find(params[:id])
   @key=@test.keys.build
   @key.keyword = params[:keyword]
   @key.position = params[:position]
   @key.save
   respond_to do |format|
     format.js
  end
  end


But despite I added :method=>:post option in server log I still see server 
"GET" request.

After an hour of hard googling I found out, that without form submitting 
link_to won''t create a "POST" request.

Kinda weird, because I don''t need any forms here and the second trouble
that Key exist only like a Model, I didn''t created controller or view
for
Key because generally I don''t need them.

So I added form:

 <% form_for add_key_test_path do |f| %>
          <div class="actions">
           <%= f.submit %>
           </div>
  <% end %>


and add_key.js.erb to manage autosubmitting:

$(''.source'').click(function(){
    $(this).$(''.actions'').submit()
});


But this doensn''t work. I spent a 2-3 hours trying to get this finally 
done, but can''t find mistake or wrong point. Any advice or help would
be
really appreciated.

You need something like link_to(result_array[k], {:controller =>
''tests'',
...}, :method => :post, :remote => true)

And you also need the rails javascript loaded so that it will add 
javascript handlers to the links that create and submit a form on the fly

The thing you call submit on is the form, so something along the lines of 

$(''.source'').click(function() {
  $(''selector that will find the form'').submit()
})

once again rails guides for the rescue 
http://guides.rubyonrails.org/form_helpers.html

chapter 1.2 Multiple Hashes in Form Helper Calls

"As with the link_to helper, the path argument doesn’t have to be given a 
string; it can be a hash of URL parameters recognizable by Rails’ routing 
mechanism, which will turn the hash into a validURL. However, since both 
arguments to form_tag are hashes, you can easily run into a problem if you 
would like to specify both. For instance, let’s say you write this:"

"Here, method and class are appended to the query string of the generated 
URL because you even though you mean to write two hashes, you really only 
specified one. So you need to tell Ruby which is which by delimiting the 
first hash (or both) with curly brackets. This will generate the HTMLyou 
expect:"
