Hello,
I followed the tutorial at:
http://khamsouk.souvanlasy.com/2007/5/1/ajax-file-uploads-in-rails-using-attachment_fu-and-responds_to_parent
However, in my controller I am getting the error:
NoMethodError (undefined method `size=’ for #SwfImage:0x5705b48)
Other references to this error indicate that the render method is
trying to render a string (which does have a size method) but it’s
attempting to render the SwfImage object instead. So how would I get
around this? Any help would be appreciated.
VIEW CODE
<% form_for(:swf_image, :url => formatted_swf_images_path(:format =>
‘js’), :html => { :multipart => true, :target => ‘upload_frame’ }) do |
f| %>
Filename
<%= f.file_field :uploaded_data %>
<%= f.submit "Create" %>
<% end %>CONTROLLER CODE
def create
@swf_image = SwfImage.new(params[:swf_image])
respond_to do |format|
if @swf_image.save
flash[:notice] = 'Image was successfully saved.'
format.html { redirect_to(@swf_image) }
format.js do
responds_to_parent do
render :update do |page|
page.insert_html :bottom, "swf_images", :partial =>
‘swf_images/image’, :object => @swf_image
page.visual_effect :highlight, “image_#{@swf_image.id}”
end
end
end
else
format.html { render :action => “new” }
format.js do
responds_to_parent do
render :update do |page|
# do nothing
end
end
end
end
end
end
