I have a number of actions that use the spreadsheet/excel library to generate an Excel spreadsheet based on model data and send it to the user using the send_file method. For a while, I''ve been testing these methods with assert_response :success, and then checking the response headers to make sure the file at least looks like what I should be getting. But it occurred to me recently that

Hello, I am trying to use send_file in my controller to serve up specific content: (.doc, ..xls) Seems to work fine in IE, but in FF (1.0.7, on Windows) after the file d/ls and the app (MS Word, MSExcel) opens up with the content, a blank window comes to the front (gets focus).

All, I have an existing form that calls an action which in turn creates a PDF and sends it to the browser using send_file. I want to change this form to use form_remote_tag so that I can set a progress bar and once the PDF is finished, the progress bar hides and the PDF opens.

While working with the newly fixed output compression plugin, one of the devs in my team discovered that it breaks with send_file().

Has anyone managed to use send_file with :stream => true? I''m currently still developing using Rails 1.1.2 on windows xp so might be OS problem.
