### Manually Add Links
Under site views there are two views, one is called 'Looks' and other one is called 'Looking'. As you can remember the one we looked at here, which I set was automatically generated is called 'Look', so that one is not showing because it was a tick box that created this whole View model and Controller. It is not necessary to build the 'Look' view again but you need to get links to it.[00:08:21](https://www.youtube.com/watch?v=tmB22d9dQ4M&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h08m21s) In 'Looks' a Dynamic Gets is used, as well as in 'Looking'. Open the Dynamic Get page. There is one called 'Looks' and 'Looking'. Go to the Looks Dynamic Get. It got a custom script area were it is asked whether the items are set or whether there are items.<<<<<<

Then we looping through them, and during the looping process we determine by $canDo script, [00:09:10](https://www.youtube.com/watch?v=tmB22d9dQ4M&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h09m10s) you will see in the helper class there's a getAction function.
The getAction function asks whether look item, where the current user has the edit option to the specific look item. If it does it in this little script, it builds an edit look button. And dynamically adds that to the edit link, which is coupled to the item, and then continues on. It dynamically generates the button for edit in the dynamic get. [00:09:48](https://www.youtube.com/watch?v=tmB22d9dQ4M&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h09m48s) You could have done that anywhere. I decided to do it here, because then it gets added to the model, which is more where your logic, for lots of your data structure should be placed. If you go back to the site views, open the looks site view. You will see that we got the main get set as looks. If you scroll down, [00:10:25](https://www.youtube.com/watch?v=tmB22d9dQ4M&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h10m25s) in this area we are looping through the look items, and echoing the edit link after the description. That means the link that we built in the Dynamic Get which is the button, will either be empty and therefore show nothing. If the user doesn't have the permission to edit it, or it will show a button. [00:11:04](https://www.youtube.com/watch?v=tmB22d9dQ4M&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h11m04s) As I look at this I haven't added a link for creating new looks. The same would be required to do that.

* ### Add A Button To Create New Looks
You could use the same button script, copy that. Here before the table, you could [00:11:29](https://www.youtube.com/watch?v=tmB22d9dQ4M&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h11m29s) add a button to create new looks. All you would need to change is this link here ((index_php?option_com_"Component") that it will have an id to zero. It will create a new look. That's a quick tutorial on how to add an editable [00:11:53](https://www.youtube.com/watch?v=tmB22d9dQ4M&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h11m53s) admin view to the site end of your component. Then link it into your side view, that you can click on a button and edit a specific id view or create more. Then control that with this getAction helper class method, which gives you whether it can be edited. You can go look at this helper class in the code. [00:12:23](https://www.youtube.com/watch?v=tmB22d9dQ4M&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h12m23s)
[00:11:19](https://www.youtube.com/watch?v=tmB22d9dQ4M&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h11m19s)
Let me just quickly open that for you. Here in the code, in helpers, we open demo.php. We scroll down until we get the method called getAction. [00:12:50](https://www.youtube.com/watch?v=tmB22d9dQ4M&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h12m50s) Around 540 depends on how much the customer scripting there is been added. You can go through this logic to see that we are dealing with a number of concepts and trying to determine the permission to edit own and to create. It all gets stored and gives back to you [00:13:17](https://www.youtube.com/watch?v=tmB22d9dQ4M&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h13m17s) in the result set. You could also echo out the result, var dump or something in the look to see exactly what is the result that you get from that structure.
The same button script may be used, copy that. Here before the table, a button could be added to create 'New Looks'. All that would need to change is this link here ((index_php?option_com_"Component") that it will have an ID to zero. It will create a 'New Look'.
If we go back to the looks view. [00:13:42](https://www.youtube.com/watch?v=tmB22d9dQ4M&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h13m42s) Let's just open that model. You will see that the custom scripting we looked at, gets added (see video) from JCB that custom scripting that creates the button. You could come in here, and you can add a var_dump);exit; and take $cando [00:14:06](https://www.youtube.com/watch?v=tmB22d9dQ4M&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h14m06s) and login as any kind of user on the site, then when you load the page, it should show you the $cando list of that specific user group. Also keep in mind that here's the authorise setting that is applicable to the looks site view. And it also controlled in the permission structure. [00:14:33](https://www.youtube.com/watch?v=tmB22d9dQ4M&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h14m33s) There's a lot of permissions automatically being added to components build in JCB. You need to always keep that in mind. It might look like things don't work while it works very well. You just haven't kept in mind that there is a permission structure, and that you need to adapt that permission on structure as it is fitting to your project.
That is how to add an editable Admin view to the site end of your component.[00:11:53](https://www.youtube.com/watch?v=tmB22d9dQ4M&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h11m53s) Then link it into your Site view, that you can click on a button and edit a specific ID view or create more. Then control that with this 'getAction helper class method', which indicates whether it can be edited. You can go look at this Helper class in the code. [00:12:23](https://www.youtube.com/watch?v=tmB22d9dQ4M&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h12m23s)
For example: In the code, in Helpers, open 'demo.php' then scroll down to the method called 'getAction'. [00:12:50](https://www.youtube.com/watch?v=tmB22d9dQ4M&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h12m50s) You can go through this logic to see that we are dealing with a number of concepts and trying to determine the permission to edit 'own' and to create. It all gets stored and gives it back in the result set. [00:13:17](https://www.youtube.com/watch?v=tmB22d9dQ4M&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h13m17s) You could also 'echo' out the result, 'var dump' or something in the 'Look' to see exactly what is the result from that structure.
If we go back to the 'Looks' view and open that model. [00:13:42](https://www.youtube.com/watch?v=tmB22d9dQ4M&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h13m42s) It will be seen that the custom scripting that creates the button, gets added from JCB(see video). You could come in here, and add a 'var_dump';exit; and take '$cando' [00:14:06](https://www.youtube.com/watch?v=tmB22d9dQ4M&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h14m06s) and login as any kind of user on the site, then when the page is loaded, it should display the '$cando' list of that specific user group.<<<<<<<
<<<<<<<<<<<<< Also keep in mind that here is the 'Authorise' setting that is applicable to the Looks Site View and is also controlled in the permission structure. [00:14:33](https://www.youtube.com/watch?v=tmB22d9dQ4M&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h14m33s) There's a lot of permissions automatically being added to components build in JCB.
