What is the best way to change a value on database when I change value on
checkbox by ajax?
I want to put a checkbox in my list of data:
ex:
<% @posts.each do |post| %>
<tr">
<td><%= post.id %></td>
<td><%= post.title %></td>
<td>
<%= button_group do %>
<%= pill_button_link_to ''Edit'', edit_post_path(post)
%>
<%= pill_negative_trash_button_link_to ''Delete'', post,
:confirm
=> ''Are you sure?'', :method => :delete %>
<% end %>
</td>
Then I want to change an boolean value from list of posts, when I change the
value of checkbox, without reloading the page.
I''m looking by the best way for do this.
Thanks by help!

I read about the Observer class, look for javascript observers and tried to find some tutorials or answer about how do it on rails. I find answers, but all about PHP.

What does this mean: "when I change value on checkbox"? Checkboxes can either be checked or unchecked. In addition, I don''t see any checkboxes in your view. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

It sounds like you want to place a checkbox on each object in an index
view, then observe the click event in JavaScript within that index
view and have the current state of that checkbox sent to an Ajax
endpoint in your controller for that model. Does that sound like a
good wrap-up?
#foos_controller
def set_status
@foo = Foo.find(params[:id])
@foo.update_attribute(:status, params[:status]);
render :nothing => true
end
#views/foos/index
<%- for foo in @foos %>
<p><%= foo.name %> <%= check_box_tag
"foos[#{foo.id}][status]", 1,
foo.status, :class => ''status'' %></p>
<%- end %>
#Prototype JavaScript
$$(''input.status'').invoke(''observe'',''click'',function(evt){
new Ajax.Request(''/foos/set_status'',{parameters: {id:
this.id.split(''_'')[1],status:$F(this)}});
});
Off the top of my head, that ought to work. Of course you''ll need to
set up a route for set_status that can take a POST.
