Hi you all, I have this piece of code in my local application: link\_to\_image “category”, {:action =\> “list\_by\_category”}… This worked fine because I have my WEBrick server ([http://localhost:3000](http://localhost:3000)) and that image pointed to “/images/category.png”, which was equal to “localhost:3000/images/category.png”. However, I’ve just uploaded my application to a server, under a directory called “ToDo” (yes, it’s the 4daysOnRails app :D). Here the image does not work, cause is referring to “[mydomain.com/images/category.png](http://mydomain.com/images/category.png)”, and the image is really located at “[mydomain.com/ToDo/images/category.png](http://mydomain.com/ToDo/images/category.png)” (under the specific “ToDo” directory). I’ve just changed that in the uploaded app (link\_to\_image “/ToDo/public/images/category”) but, how can I put the link so it works at both places? Thanks a lot. PT: I’ve seen the url\_for stuff, but I don’t know how to use it with this… ---

Try to install your on a subdomain rather than just a subfolder. Also be very careful that your config/database.yml is not publically accessible or you could find your entire database hacked one day. ---

I think whant you want to do is set the asset\_host configuration parameter for production mode to “/ToDo” You might need to be wary of [http://dev.rubyonrails.org/ticket/5406](http://dev.rubyonrails.org/ticket/5406) Fred ---

However, I don’t really know how Rails set the URL’s, cause: 1: controllers and actions in the controllers are set correctly: /ToDo/items/…, not /items… 2: Style sheets are also in the public directory but Rails get them correctly (/ToDo/public/stylesheets/…, not /public/stylesheets… ) ---

After the change is ToDo/ToDo/public… so it does not work – With images (which was my initial problem):…nothing has happened! The url is still /images/image.png… What can I do? ☹
