ajax - Rails respond_to redirect not working -

the respond_to block in create controller in rails app not redirecting on successful save... i'm sure simple solution, inexperienced rails , first time encountering problem.

the form set :remote => true, , controller follows...

def create     @store = current_user.stores.new(store_params)      respond_to |format|         if @store.save             format.html { redirect_to root_path }         else             format.html { flash[:alert] = "save failed! #{@store.errors.full_messages.join(";")}"              render "new" }             format.js {}         end     end end 

and while i'm on subject, code else portion of conditional doesn't run either, except format.js {}, run code in create.js.erb file (an alert, time being).

i'm working rails 4.2.5. can me understand why redirect , alert not working? thank you!

editing show solution based on rich's answer, here's solution came with:

controller:

def create     @store = current_user.stores.new(store_params)      flash.now[:alert] = "save failed! #{@store.errors.full_messages.join(";")}" unless @store.save      respond_to |format|         format.js     end      if @store.save         flash[:notice] = "new store created"     end end 

create.js.erb

<% if flash.now[:alert] %>     $("#alert_holder").empty();     $("#alert_holder").append("<%= j flash.now[:alert] %>"); <% else %>     window.location.href = "<%= root_url %>"; <% end %> 

note needed add quotes around redirect url.

on form success, page redirects root. on failure, error message flashes form not refreshed - answers user has entered remain.

remote: true ajax request.

ajax javascript, , such invoke format.js method:

def create     @store = current_user.stores.new store_params      respond_to |format|         if @store.save             format.js             format.html { redirect_to root_path }         else             format.js             format.html { flash[:alert] = "save failed! #{@store.errors.full_messages.join(";")}"              render "new" }         end     end end 

the format.js method call /app/views/[:controller]/[:action].js.erb file, fire of js have inside it.

if don't want have js format handling response, you'll have away respond_to , have you'd return (redirect_to won't work).

ajax

there several stipulations need appreciate this:

• ajax cannot "redirect" (on own)
• ajax treated js in rails controller
• you have "hack" flash working through js

if don't have experience ajax, simple explanation it's "pseudo-request"; sends http request without having reload browser.

the pattern ajax simple: ajax request > server > ajax response

you cannot "redirect" via ajax unless parse response javascript. ajax acronym (asynchronous javascript , xml) suggests, response expected xml (ie no functionality).

to answer question, you'll need use flash.now "flash" message, , handle response .js.erb file:

def create     @store = current_user.stores.new store_params     flash.now[:alert] = "save failed! #{@store.errors.full_messages.join(";")}" unless @store.save      respond_to |format|         format.js         format.html     end end 

this allow call...

#app/views/stores/create.js.erb <% if flash.now[:alert] %> alert("<%=j flash.now[:alert] %>"); <% end %> window.location.href = <%= root_url %>;

your new code can improved little :

def create     @store = current_user.stores.new store_params      if @store.save         flash[:notice] = "new store created"     else         flash.now[:alert] = "save failed! #{@store.errors.full_messages.join(";")}"     end      respond_to |format|         format.js     end end 

if wanted dry code more, you'll want @ responders gem:

#app/controllers/stores_controller.rb class storescontroller < applicationcontroller    respond_to :js, only: :create     def create       @store = ...       respond_with @store if @store.save    end end
