Rails - Mar 2008 - How to upload a file

Hello all,

i am trying to upload a file through Ruby on Rails since last week.
Could anyone please guide me regarding a simple upload process. Or
guide me to a ''working'' example/tutorial of uploading.

Waiting curiously for a respons,

Regards,

pharrukh.

the super simple version:
in your view place a form:

<% form_tag(...insert your path etc...), { :multipart => true }) do %>
  <label for="file">File to Upload</label><%=
file_field_tag "file" %>
  <%= submit_tag("upload") %>
<% end %>

then you''ll get this file in your action as params[:file] and can save 
it like this:

File.open("#{file_location}/new_file_name.xxx",
''wb'') { |f|
f.write(params[:file].read) }

The important bit that''s easy to forget is the :multipart=>true


==> in your view new.rhtml <=
<% form_for(:something, @something, :url => somethings_path, :html =>  
{ :multipart => true }) do |f| -%>
   <p> <label for="something_data">Something
File</label>:<br />
     <%= f.file_field ''data'' %> </p>

   <%= submit_tag "Submit", :name => nil %>
<% end %>


==> in the SomethingController#create action <=
     data = params[:something].delete(''data'') #  
HashWithIndifferentAccess still needs the actual key type to .delete

     params[:dump] = "data=#{data.inspect}"#;  
filename=#{data.original_filename}; content_type=#{data.content_type}"

     if data.blank?
       flash[:error] = "No something file selected for upload"
       redirect_to :action => ''new'' and return
     end
     content = data.read
     if content.blank?
       flash[:error] = "Selected something file was empty"
       redirect_to :action => ''new'' and return
     end


That should get you going.
