copied!<p>After several hours and lots of other posts I got to a final solution:</p> <p>Bricker is right in that it is not possible for rails to render more than once in a call, as taken from <a href="http://guides.rubyonrails.org/layouts_and_rendering.html" rel="nofollow">http://guides.rubyonrails.org/layouts_and_rendering.html</a> "Can only render or redirect once per action"</p> <p>The site also states "The rule is that if you do not explicitly render something at the end of a controller action, Rails will automatically look for the action_name.html.erb template in the controller’s view path and render it."</p> <p>Then, the solution that worked great for me was to tell the controller to render to a string if a download flag (download=true) was set in :params (I also use request.url to have it working from any view in my application)</p> <p>View:</p> <pre><code>= link_to 'Download', request.url+"&downloadexcel=true", :class => 'btn btn-primary btn-block' </code></pre> <p>Controller:</p> <pre><code>def acontrolleraction #some controller code here if params[:downloadexcel] save_page_xls else # render normally end end def save_page_xls #TRESCLOUD - we create a proper name for the file path = URI(request.referer).path.gsub(/[^0-9a-z]/i, '') query = URI(request.referer).query.gsub(/[^0-9a-z]/i, '') filename = @project_data['NOMBRE']+"_"+path+"_"+query+".xls" #TRESCLOUD - we render the page into a variable and process it page = render_to_string #TRESCLOUD - we send the file for download! send_data(page, :filename => filename, :type => "application/xls") end </code></pre> <p>Thanks for your tips!</p>
