Hi I’m sure this is in the wrong group - so any suggestions for a right group would be great! And you have my express permission to treat me like an idiot in replies! I have a fair amount of knowledge … but … obviously not enough to understand this past the basics! I have two problems … but only going to list one for now … I’m trying to use the Jim N. code and examples with swfupload and not having much success. I’m using Rails 2.3.5 if that’s any use. I’ve already had to do this in my PhotosController: skip\_before\_filter :verify\_authenticity\_token, :only =\> :create just to get the app to ignore {play nicely?) with the InvalidAuthenticityToken problems! And I promise I’ve read EVERY post there is on the problem from Google and beyond. I’ve changed more code try to solve the InvalidAuthenticityToken than I think Microsoft have ever produced … and still no help. More on this in another post … But back to my problem: I have this as part of my photo controller code: def create if params[:Filedata] @photo = TripPhoto.new(:swfupload\_file =\> params[:Filedata]) if @photo.save render :partial =\> ‘photo’, :object =\> @photo else render :text =\> “error” end else … [rest omitted] The data is being passed to the controller I think from the log … Processing TripPhotosController#create (for 127.0.0.1 at 2010-05-17 21:24:26) [POST] Parameters: {“Filename”=\>“SYTS Logo Colour - All Red.png”, “trip\_id”=\>“3”, “action”=\>“create”, “authenticity\_token”=\>"[Omitted]", “Upload”=\>“Submit Query”, “controller”=\>“trip\_photos”, “\_worldtripper\_session”=\>"[Omitted]", “Filedata”=\>#\} But I get the following error … NoMethodError (undefined method `file=' for #): app/models/trip_photo.rb:13:in`swfupload\_file=’ I have inserted (as per Jim’s instructions) the following into my TripPhoto Class… require ‘mime/types’ class TripPhoto \< ActiveRecord::Base belongs\_to :trip has\_attached\_file :photo, :styles =\> { :small =\> “150x150\>”, :large =\> “320x240\>” } validates\_attachment\_presence :photo validates\_attachment\_size :photo, :less\_than =\> 5.megabytes def swfupload\_file=(data) data.content\_type = MIME::Types.type\_for(data.original\_filename).first.content\_type logger.warn(“Data content type is: #{data.content\_type}”) self.file = data end end So I have a feeling it has something to do with the line: self.file = data But I really have NO IDEA what is wrong! I’ve spent days on this and it’s not through lack of trying … So any help please would be fabulous! Thanks Darren Oh … BTW … If I make the line @photo = TripPhoto.new(params[:Filedata]) … I end up with the following error: NoMethodError (undefined method `stringify_keys!' for #): app/controllers/trip_photos_controller.rb:20:in`new’ Which makes even less sense … ---

Hi I solved it … but have no idea why! Needed to change: self.file = data to self.photo = data And it works … hmmmm … On May 18, 7:10 pm, “Ruby on Rails: Talk” [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid) ---

More on this in another post … I recently configured swfupload with Rails using the beta3 of swfupload so I could have it to client side image resizing. Take a look at this rails demo app: [http://philip.pjkh.com/swfupload-rails-resize-demo.tgz](http://philip.pjkh.com/swfupload-rails-resize-demo.tgz) It’s everything you need to get it going. If you don’t want the client side image resizing, just comment out the bits that invoke it. The swfupload handlers are setup to simply print out debugging information so you can see when/why/where they get called. Just run ‘rake db:migrate’ to setup the sqlite database. In particular though… look at these files/lines… app/middleware/flash\_session\_cookie\_middleware.rb config/environment.rb - 2nd to last line config/initializers/session\_store.rb - last line app/models/photo.rb app/controllers/home\_controller.rb app/views/home/index.html.erb public/javascripts/swfupload\_handlers.js -philip ---

Thanks so much for you help with the problem and the suggestion with new version of swfupload! I don’t suppose you have any clear insight into why I can’t get the InvalidAuthorizationToken thing to work do you? Thanks once again for help already given and any more you might be able to offer Darren ---

My guess is you’re not passing it along via Flash. See this bit in app/views/home/index.html.erb where I invoke the swfupload object. See where it’s passing the session key and the authenticity token? That’s important. And also why you need that middleware stuff. $(document).ready(function() { swfu = new SWFUpload({ upload\_url : “\<%= upload\_path %\>”, file\_post\_name : “Filedata”, post\_params : { “\<%= key = ActionController::Base.session\_options[:key] %\>” : “\<%= cookies[key] %\>”, “\<%= request\_forgery\_protection\_token %\>” : “\<%= form\_authenticity\_token %\>” }, > Thanks once again for help already given and any more you might be > able to offer No problem! -philip ---

Good to know. That won’t help with the authenticity token though… But definitely handy if you need more cookies than just the session! -philip ---

Note to self: don’t answer mailing list replies while half asleep 🙂 Best regards Peter De Berdt
