Question

I’m fairly new to Ruby on Rails.

I’ve made a blog, and loaded a few entries include title, content and image (which is a string detailing the path of the image).

I’ve had a search around and can’t find a solution – I was just wondering whether there is a way that I can reference the data within the image field in an image_tag, so that the image field links to the relevent image?

Thanks.

Assuming You can use the following:

<%= image_tag blogentry.image, :alt => 'Whatever' %>

This supposes a few things:

• your images are store in /app/public/images or /app/assets/images
• your model is called blogentry (change accordingly)
• your image field contains the relative path from the public/images (or assets/images) folder
• your ìmage` field also contains the file name and extension

and if the path is always the same, you can do the following

<%= image_tag "path/to/your/image/#{blogentry.image}", :alt => 'Whatever' %>

in this example, the path to your images would be app/public/images/path/to/your/image/ (or app/assets/images/…).

This also assumes your field contains the name and the extension.
