I'm facing the following problem: I have a very small image gallery with image files located in the following directories
app/assets/images/locale/thumbs/
app/assets/images/locale/big/
I have to create a hyperlink that as a content has a thumb image and as a target - its bigger version from app/assets/images/locale/big/ folder:
<a href="path-to-full-size-image-001.jpg">
<img alt="first photo preview" src="/assets/locale/thumbs/001.jpg" />
</a>
I'm doing this by means of
= link_to(image_tag("locale/thumbs/001.jpg"), "locale/big/spizzicaluna001.jpg")
In fact I have tried many variants for the second argument of link_to but with little success - the bigger file can not be found.
How to resolve this issue?
There are two approches to this issue.
You must specify the assets folder in the path.
link_to( image_tag("locale/thumbs/001.jpg"), "/assets/locale/big/spizzicaluna001.jpg" )
Use an image path allowing rails to find the correct image
link_to( image_tag("locale/thumbs/001.jpg"), image_path( "locale/big/spizzicaluna001.jpg") )
