I'm trying to show a flash message and render it with Ajax, but the message does not seem to be appearing until after I refresh the page.
Here's my create.rjs file:
page.insert_html :top, :feed_items, :partial => 'shared/feed_item', :object => @micropost
page.replace_html :user_info, pluralize(current_user.microposts.count, "micropost")
page[:micropost_form].reset
page.replace_html :notice, flash[:notice]
flash.discard
Here's the relevant part of my application layout view:
<div id= "notice"><% flash.each do |key, value| %>
<div class="flash <%= key %>"><%= value %></div>
<% end %></div>
And here's the relevant part of my micropost controller:
class MicropostsController < ApplicationController
before_filter :authenticate, :only => [:create, :destroy]
before_filter :authorized_user, :only => :destroy
def create
@micropost = current_user.microposts.build(params[:micropost])
respond_to do |format|
if @micropost.save
flash[:success] = "Micropost created!"
format.html { redirect_to root_path }
format.js
else
@fee开发者_高级运维d_items = []
render 'pages/home'
end
end
end
So why isn't the flash message showing up right away?
Flash messages by design are stored in the session until the next page load. In the case of ajax, don't use flash. For one thing, the div to replace the message into may not exist, so you need to add that to your page as a container to add to. Second, just do it from a regular variable, not flash.
A regular variable would be:
@message = "Micropost created!"
instead of the flash[:success]
The js view would use this variable instead of flash.
Instead of page.replace_html :notice, flash[:notice]
Try this page.replace_html :notice, "Some info to flash"
