railsajaxupload
Normally, to upload file,we will write some codes in the view page like:
{:action => :create}, :html => { :multipart => true}) do |form| -%>Upload A Image:
Now,I coded some line of js, append to public/javascript/ application.js now we just need to change little things as: change: form_for => remote_form_for add: :ajaxupload => true
Then we got:
{:action => :create}) do |form| -%>Upload A Image:
Now, file upload will post via a iframe without refresh the page.
But how about the rjs? We won't forget it. Add some codes in the controller as bellow:
- iframe request
if params[:HTTP_X_REQUESTED_WITH] && request.post?
render :template => 'photos/create.rjs', :layout => false, :content_type => 'text/html'
else 1. normal request
respond_to do |format|
format.html {redirect_to :action => 'new', :id => @photo if request.post?} format.js
end
end
Now we can render different views by the request type automatically.
