Ruby-on-rails – Ruby On Rails, forced users to download TMP files

def download
 file_path = "#{RAILS_ROOT}/tmp/downloads/xxx.html"
 data = render_to_string( :action => :show, :layout => nil )
 File.open(file_path, "w "){|f| f << data }
 flash[:notice] = "saved to #{file_path}"
 end

 /Users/xxxx/Documents/Sites/xxxx/Website/htdocs/tmp/downloads/xxxx.html

redirect_to file_path

send_file Rails.root.join('tmp','downloads','xxxxx.html'), :type =>'text/ html', :disposition =>'attachment'

# For nginx :
config.action_dispatch.x_sendfile_header ='X-Accel-Redirect'

I created a file in the tmp directory, which contains the following controller code:

def download
 file_path = "#{RAILS_ROOT}/tmp/downloads/xxx.html"
 data = render_to_string( :action = > :show, :layout => nil )
 File.open(file_path, "w"){|f| f << data }
 flash[:notice] = "saved to #{file_path} "
 end

This will create the file I want in the tmp directory, all I want to do is force the user to download the file.

On my local computer Above, save the file to the following path:

/Users/ xxxx/Documents/Sites/xxxx/Website/htdocs/tmp/downloads/xxxx.html

On the live server, this URL will be something completely different.

I want to know How to force users to download this xxxx.html?

Attachment:
If I put…

redirect_to file_path

…On the controller, it just gives me a notice The route found.

Cheers.

Look at the send_file method. It looks like this:

< p>

send_file Rails.root.join('tmp','downloads','xxxxx.html'), :type =>'text/html', :disposition =>'attachment' 
: disposition =>'attachment' will force the browser to download the file instead of rendering the file. If you want to load in the browser, set it to "inline". If nginx is in front of your Rails application , Then you will have to modify your environment configuration (ie. environment / production.rb):
 
 
# For nginx:
config.action_dispatch.x_sendfile_header = ' X-Accel-Redirect'
