in case someone else has similar problems, the code that I got working
is:
downloading:
--------------------------------------------------------------
controller: datafiles_controller
def download
@datafile = Datafile.find(params[:id])
send_file('/var/www/pub.website.com/file_uploads/'+
@datafile.name , :disposition => 'inline')
end
View: index.html.erb
<% for datafile in @datafiles %>
<%= datafile.name %>
<%= link_to("Download
File", :action=>'download',:controller=>'datafiles',:id=>datafile) %>
<% end %>
routes.rb
resources :datafiles do
member do
get :download
end
end
uploading:
---------------------------------------------------------------------------
datafiles_controller:
def create
u_id = session[:user_id]
@file = params[:upload]
post = Datafile.save(params[:upload],u_id)
if post
post = Datafile.event(u_id,"Uploaded","File",
@file['datafile'].original_filename)
flash[:notice] = 'File has been uploaded successfully.'
redirect_to :action => 'new'
else
flash[:notice] = 'File was not uploaded (invalid data).'
redirect_to :action => 'new'
end
end
datafiles view: new.html.erb
<% form_tag( { :action => 'create' }, :multipart => true ) do %>
<% flash.each do |key, value| %>
<%=value%>
<% end %>
<div class="label_div">Select File:</div>
<%= file_field 'upload', 'datafile' %>
<%= submit_tag "Upload" %>
<% end %>
datafiles view: index.html.erb
<% for datafile in @datafiles %>
<tr>
<td class="tt">
<%= datafile.name %>
<%= link_to("Download
File", :action=>'download',:controller=>'datafiles',:id=>datafile) %>
</td>
<% @user = User.find(datafile.user_id) %>
<td class="tt"><%= @user.full_name %></td>
<td class="tt"><%= datafile.created_at.strftime("%m/%d/%Y at %I:
%M%p") %></td>
</tr>
<% end %>
