Rails 3.1中的图像-投入生产

Question

My articles have images. I put the images in app/assests/images and store their location in a field in the database.

Then I can display them in by using:

<%= image_tag(@article.image) %>

But when I move to the production server, none of my images show up! The server's looking for assets/blank-d5dd6e3683b4753dfde3c70cf61f99b6.png rather than blank.png and it isn't available.

How do I sort this?

Answer 1

This is a problem I ran into when Rails 3.1 was released.

Normal assets

If your assets are manually placed by you then all you have to do is run:

rake assets:precompile

This will precompile your assets into public/assets .

It's best to precompile on your production server so you don't have unessential files on your development server.

Uploaded assets

If you are uploading images using something like Paperclip , then don't use the asset folder.

You need put your images in the public folder. In your case probably public/assets/articles
