Send_data with a layout?

Hello, I’m using send_data to retrieve binary (images) from the database. It works fine, this is my controller : @picture = Picture.find(params[:id]) @image = @picture.image_file send_data (@image, :type => @picture.image_content_type, :filename => @picture.image_file_name, :disposition => ‘inline’) However, when a user navigates to that action, all it shows is a picture. Is there a way to render the layout as well, and have the send_data put the picture in a layout? instead of just displaying a picture?

ie Could I have the send_data place it in the <%= yield %> ?

Bingo!

No need for send_data in the first place.

This was all i needed, in the view: <%= image_tag(“/pictures/#{@picture.id}”, :alt => “Image”) %>

Now the image displays inside a layout. Sweet.

That’s not how it works. If you want your picture to be in a HTML layout, you’ll need to make a controller that serves a HTML page with the image in it, i.e. image_tag(url_for_your_image_like_mentioned_above). That image tag will then query your image controller (the one where you send that data from) for the picture. send_data does exactly what it says: it sends the image data over, nothing more.
