Now, every video should be represented by a hyperlink. Click on
the video. You should see an empty form. In the next step, we
will add behavior to this form. We'll populate the form on load
and handle clicking the Save button. Step Three: Implement the
Controller Now we have two options. We can create a new
controller, such as , or reuse an existing one ( ). the best
solution? The answer is: there is no best solution. It all
depends. If the two cases (adding and editing) have many
similarities and few differences, it makes sense to create a
controller that handles both cases.
You need some conditional statements to differentiate between
add and edit scenarios. On the other hand, if the behavior in
the two cases is quite different, you'll end up with a lot of
ugly conditional Phone Number List

statements in one controller. In this
case, it's better to split them into two different controllers.
Before writing this step of the tutorial, I started by reusing
the same controller, but I wasn't very happy with the end
result. So, I decided to separate them into two different
controllers. In , create a new controller that looks like this:
Let me explain what's going on here.

First, this controller, unlike ours, has four dependencies. We
have an additional dependency here: , which we use to access
parameters in the route. In this case, the of the video to edit
will be our route parameter. In the body of this controller,
first we use the service to get the object to use with our
endpoint. But this time, we use the service differently. Video
Update: Method: The first parameter is the of our endpoint.
However, here we have a route parameter indicated by a colon (
). We use parameterized routing because the two endpoints we
created earlier in this section contain route parameters. The
second argument to get this method is an object that provides
default values for the parameter in our route.
