Rails how does link to work

Using documentation locally is helpful, especially if you can integrate it into your editor. If not you can always use ri in your terminal of choice. Another favourite of mine is the awesome ApiDock. You will probably want some sort of confirmation when removing objects to prevent accidental deletes. The easiest way to add that is with a simple javascript alert box that will ask the user to confirm his delete request.

Making an image link-able is pretty straight forward. The generated alt tag is just the name of the image file, capitalized. Alt attributes are beneficial for SEO purposes and they also aid those visitors who use text readers or non graphical browsers.

These types of methods get generated all the time. Also here there is a lot going on. But the last two are hashes, so it's a little tricky to differentiate between the two unless we explicitly use curlies. You can see all of your routes by running rake routes in your app root directory. It actually has nothing to do with the view that you use it in. The precondition for this is that you're declaring the Profile routes in your routes. Here's an example:. The docs are a great reference on this.

We also need to add the word path. Make sure you have closed your tag off with the ending bracket. Both will take us to the same page. Remember the items in the first column of the routes table are called Prefixes, which means they have an option. Accordingly, they can either end in path or url. We can test these values by displaying them in the browser. Next, I'll copy the code and change path to url , so we can discern the difference. It means, the path relative to the actual URL.

This is what you're usually going to do. However, the url version can very useful in some specific circumstances. If I had a subdomain configured, then this link would actually go to that sub domain. The other reason to use URL is when sending an email. Imagine you're sending a link in your email. Let's revert back to our previous code, by removing the subdomain portion. I'm also going to remove the manual portion. So, the only code that'll be present is:. For creating a new item, it makes sense to have it right at the top of the page because you don't want to have multiple links for creating a new item.

However, for edit, you want to have a link for each portfolio. Now we need the path. I'm showing you this step because I want you to know how the process works. Also, when you're no longer using a tutorial, but building out your own application, I want you to know what my process is for referencing which route I need to use.
