Hey all,
I'm still sorting out some of the basics here, and I still can't quite find an explanation of how the file_data variable (object?) behaves if I'm going to be putting multiple file upload tags on the same page. Can someone give me a quick rundown or point me to a link/previous thread?
Thanks, Jeff
You must give each of them a unique name and then you'll get a param for each of them. Otherwise it won't work.
If you need this for a real world app you may consider using swfupload instead, since it's more comfortable for the user (but more difficult to implement)
In your view:
<label for="files">File </label> <%= file_field_tag 'files' %>
And id suggest putting it in a partial and then getting an ajax link that renders one each time.So assuming, you put the above lines in a partial called _file_form.html.erb then you want something like:
<div id="file_forms"></div>
<%= link_to_remote( "Add another file :update => "file_forms", :url => { :action => :add_file_form }, :position => "bottom" ) %>
Which calls a controller method calles add_file_form wich is basically:
def add_file_form render(:partial => 'file_form') end
Ajax aside, the function that hadles the params should look something like:
def include_files params[:files].each_with_index do |file, index| model = ModelName.new( :uploaded_data => file ) if model.valid? # save or attach to other or do whatever you need else # your data was not valid. so redirect, flash, whatever end end end
please nopte that i am using the plugin attachment_fu to upload and handle binaries. and my example is used with images, so i have to validate the files size and type before i save it.
hope it helps
