Redirection in format.json

I have presently a render :json which modify the current page

  if @request.save
     format.html { redirect_to(@request) }
    format.json { render :json => { :result => 'success', :request

=> request_path(@request) } }

but I would like rather to redirect to an index page
I wrote this but it doesn’t redirect …

    format.json { redirect_to requests_url }

what should I write to redirect correctly to an html page ?

thanks for your help

Here is an example:

format.json { render :json => { :redirect => requests_url } }

and then on your client redirect like this:

if (json.redirect) {
window.location = json.redirect;
}

Also try http://www.google.com/search?q=json+redirect

Does this solve your problem?

thanks for your help

it seems that json.redirect is bypassed…
I put an alert, and it’s not fired up

if (json.redirect) {
alert(‘redirect’);
}

in my controller the create action is :

respond_to do |format|
  if @request.save
    flash[:notice] = 'Request was successfully created.'
    format.html { redirect_to requests_url }
    format.xml  { render :xml => @request, :status => :created, 

:location => @request }
format.json { render :json => {:result => ‘success’, :redirect
=> requests_url } }
format.js
else

once the request is saved, … I get in the log

Completed in 563ms (View: 1, DB: 5) | 200 OK [http://localhost/requests]

I should have
200 OK [http://localhost:3000/requests]

Maybe you’re not requesting it properly, making sure that you call the
format.json part? It seems it redirects to requests_url in format.html.

Just to clarify: A proper json request is to call /path.json or call
/path
(with or without .json) with an “Accept: application/json” header.

yes… after some tests, I rewrote the original format.json line (from
the plugin uploadify_rails) as :

    format.json { render :json => { :result => 'success', :request 

=> member_request_url(@request[:id]) } }

this redirects to :show (don’t misunderstand it , ‘request’ is my
model instance…)
and I just modified the :show action as following :

respond_to do |format|


format.js {
render :update do |page|
page.redirect_to member_requests_url
end
}
end

this time, the redirection is fine… which is enough for my test,
I’ll try to investigate a little bit more to understand why:

    format.json { render :json => { :result => 'success', :request 

=> member_request_url(@request[:id]) } }

redirects to :show with a format .js

I thought I could write a :callback => ‘index’, no change… it’s always
redirected to :show…
OR is it an issue in using :request =>
maybe this is a parameter used by the render.json …

thanks a lot for your help

Again: Make sure that format.json is in fact called. Maybe try removing
format.html to make sure that the redirect isn’t done there.
