Hello,
I am updating an object with an AJAX form:
view:
<% remote_form_for(@sample, :update => "content2") do %>
<p>
parameter: <br />
<%=
select("sample","parameter",Parameter.find(:all).collect
{|p|
[p.description.gsub(''_'', ''
''),p.id]},{},{:size => 4, :multiple =>
true}) %>
</p>
<%= submit_tag "add" %>
<% end %>
once form is sent, object is saved in def update in my controller:
controller:
def update
@sample = Sample.find(params[:id])
if @sample.update_attributes(params[:sample])
flash[:notice] = ''Sample was successfully updated.''
redirect_to(@sample)
else
render :action => "edit"
end
end
my problem is that redirect_to(@sample) call the show method via a
HTML request, so all my page is refreshed when the view show.html.erb
is displayed...which is not what i want as i sent the form through
AJAX in order to update the DOM "content2"
Is it possible to change redirect_to so that the call of def show is
done through xmlhttprequest and only my partial _show.html.erb is
displayed (I already have a show.js.rjs)?
I tryied to play with format in update but i always get an argument
error when request is done via AJAX.
def update:
respond_to do |format|
if @sample.update_attributes(params[:sample])
flash[:notice] = ''Sample was successfully updated.''
format.html {redirect_to(@sample)}
format.xml_http_request :get, "show",:id => @sample
else
render :action => "edit"
end
May be i am not using correctly the xml_http_request function.
thank you for your help.

> format.xml_http_request :get, "show",:id => @sample > May be i am not using correctly the xml_http_request function.You are correct. I don''t know what xml_http_request is actually supposed to do, but this should read something more like: respond_to do |format| format.html { redirect_to(person_list_url) } format.js format.xml { render :xml => @person.to_xml(:include => @company) } end format.xml_http_request { ... } would be looking for a template something like: show.xml_http_request.erb Of course in reality, it just breaks.> respond_to do |format| > if @sample.update_attributes(params[:sample]) > flash[:notice] = ''Sample was successfully updated.'' > format.html {redirect_to(@sample)} > format.xml_http_request :get, "show",:id => @sample > else > render :action => "edit" > > endThis also feels wrong to me. Maybe something more like: if @sample.update_attributes(params[:sample]) flash[:notice] = ''Sample was successfully updated.'' respond_to do |format| format.html {redirect_to(@sample)} format.js end else render :action => "edit" end -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Hi Robert, I indeed did try with format.js. It occurs an error: template is missing, Missing template samples/update.js.erb. as I say i already have a show template and show.js.rjs that is doing everything necessary if def show is called by an AJAX request. that why i would like to call def show via an xmlhttprequest but from def update in the controller ( i am not sure i am really clear) and i think that is what xml_http_request is supposed to do (but i can be wrong as i am new to AJAX and co).

What you can do is if xhr? ... end (xhr? is an alias for xml_http_request?) which can tell if the request was submitted by prototype.
