Hi,

i need to post a form using AJAX so that I can update and save my  
object:

form:  
\<% form\_for(@sample,:html =\> {:id =\> “analyses\_list”}) do %\>  
**Analyses:**

 \<%= render :partial =\> 'parameters/parameter\_name', :collection =\> @parameters %\> 
\<% end %\>

if I am using link\_to\_function in order to post the form, everything  
is alright except that it’s not an AJAX request, but at least the  
action update is called:

link:  
\<%= link\_to\_function(“Remove an analysis from sample # #{@sample.id}”,  
“if (confirm(‘Are you sure you want to remove those analyses?’)) $  
(‘analyses\_list’).submit();”) %\>

I try using link to remote, but i have a problem with the url  
parameter, i cant get the link to send the request to the update  
action.

\<%= link\_to\_remote “Remove analyses from sample” ,{:url =\> {:action =\>  
‘update’, :id =\>@sample}}, {:confirmation =\> true,:submit =\>  
‘analyses\_list’} %\>

i also tried  
{:url =\> sample\_url(@sample), :method =\> :put}

i already try with

form:

\<% remote\_form\_for(@sample,:html =\> {:id =\> “analyses\_list”}) do %\>  
**Analyses:**

 \<%= render :partial =\> 'parameters/parameter\_name', :collection =\> @parameters %\> 
\<% end %\>

link:

\<%= link\_to\_function(“Remove an analysis from sample #  
#removed\_email\_address@domain.invalid}”,  
“if (confirm(‘Are you sure you want to remove those analyses?’)) $  
(‘analyses\_list’).submit();”) %\>

but if the update action is correctly done, my update.js.rjs is not  
called and i get an error

Missing template samples/update.html.erb in view path F:/Programmation/  
ROR/LIMS/app/views

which mean that update is dealing with an regular http request, not  
AJAX one. As my link is not in the form itself i assume that is the  
link that need to perform the AJAX request, not the form.

i finally mange to get it works it was quiet obvious in fact:  
link:

\<%= link\_to\_remote “Remove analyses from sample # #{@sample.id}” ,:url  
=\> {:action =\> ‘update’, :id=\> @sample}, :confirmation =\> true,:submit  
=\> ‘analyses\_list’ %\>
