<font face="Default Sans Serif,Verdana,Arial,Helvetica,sans-serif" size="2">So I have been thinking about this topic a bit more and here are my thoughts on it.<div><br></div><div>First, I think having a hybrid approach is do-able, as long as we know ahead of time what are the extension points we want to support. I am afraid that if you ask someone this question, the answer would be everything. The way we are writing code now is extremely modular, so supporting "everything" down the road is not impossible to do - but having a clear list of extension points we want to extend right now would be helpful because it would allow us to move forward. If we try to support "everything" right now, I don't think we are going to get anything done.<div><br></div><div>Ok, so assuming we have this list say: batch-actions, actions, and workflows. A hybrid approach would be possible using services and HTML. So something like this would work. <span style="font-size: 12.8000001907349px;">This way, you can still support your extensions and still have an easy way to customize your view via HTML markup.</span></div><div><br></div><div>table.controller.js</div><div>-------------------</div><div>ctrl.batchActions = myBatchActionsService;</div><div>ctrl.rowActions = myRowActionsService;</div><div>ctrl.workflows = myWizardWorkflowService;</div><div><br></div><div>table.html</div><div>-----------</div><div><tr><th><action-list list="myBatchActionsService"></action-list></th></tr></div><div>....</div><div><span style="font-size: 12.8000001907349px;"><tr ng-repeat="item in ctrl.data"></span></div><div><span style="font-size: 12.8000001907349px;"> <th>{$ item.name $}</th></span></div><div><span style="font-size: 12.8000001907349px;"> <th><action-list list="myRowActionsService"></action-list></th></span></div><div><span style="font-size: 12.8000001907349px;"></tr></span></div><div><span style="font-size: 12.8000001907349px;"><tr class="details-row">...</tr></span></div><div><br></div><div>But what if I want to add addition columns? well, just modify the HTML directly. All you need to do is add <th> and <td> tags. But what if I have multiple teams editing the same HTML file? For columns, I think the behavior is probably additive, meaning that we are going to add more columns, not take-away or modify existing ones. If you're not taking-away columns, then your merge conflict should be easy to resolve. And if you are modifying existing ones, you're going to run into merge conflict no matter what (whether its in your HTML, controller, or service). I do not think it is possible to show two different things in the same place, as you are competing for screen real-estate. So a manual resolution is required no matter what you do.</div><div><br></div><div>I think the goal is to make it EASIER to extend and address as much of the pain points as much as possible. If we had to make everything extensible from the gecko, I think we are shooting ourselves in the foot. So my proposition for now is, lets choose what we want to extend and work with that so we can move forward. This will then allow us to continue defining presentation related stuff in markup and address Travis' concerns.</div><div><br></div><div><br><font color="#990099">-----"Tripp, Travis S" <<a href="mailto:travis.tripp@hp.com" target="_blank">travis.tripp@hp.com</a>> wrote: -----</font><div class="iNotesHistory" style="padding-left:5px;"><div style="padding-right:0px;padding-left:5px;border-left:solid black 2px;">To: "OpenStack Development Mailing List (not for usage questions)" <<a href="mailto:openstack-dev@lists.openstack.org" target="_blank">openstack-dev@lists.openstack.org</a>><br>From: "Tripp, Travis S" <<a href="mailto:travis.tripp@hp.com" target="_blank">travis.tripp@hp.com</a>><br>Date: 08/21/2015 02:44PM<br>Subject: Re: [openstack-dev] [Horizon] Update on Angular Identity work<br><br><div><font face="Courier New,Courier,monospace" size="3">I definitely think the two panel tables in tree now (images and users) should be reduced down in the number of html partials. On initial glance, it seemed pretty easy to just look at the files and know where things are. However, in practice, it makes it error prone and harder to see everything when the header file is separated from the row file. I will put up a patch that at least collapses the HTML fragments down on images, so that can be seen.<br><br>I also think that more sections of the html should be reduced to additional fine grained directives, such as the table footer directive Cindy has nearly ready. And these finer grained sections could be combined into a template used by a *basic* full table directive as mentioned below in option 1.<br><br>Option 1’s primary strength actually is that it is more rigid and more contract like. The data and the html are mostly separated, meaning you change the data inputs and can centrally control the template. I think for very simple tables, option 1 is probably better. However, that also becomes a firewall of sorts for customizability and ease of making changes.<br><br>When it comes to composability, reusability, extensibility, customizability, and readability I don’t think option 1 handles all those aspects better. To achieve simple results, I think it actually can later lead to a lot of complexity in JS that could be solved directly by modifying html.<br><br>When I looked at the option 1 below, and thought about how we have different representations of data that should go in table cells that would need to be handled. I also did not see any mention of how the collapse / expand details drawer would be handled and I actually have a lot of concerns on how that would really work or be simple to use or achieve, because the collapse expand details may differ quite a bit on what we want to display.<br><br>We’ve already used the table drawer in a number of ways based on the data we want to show (horizontal property listings, vertical property listings, qutoa charts, nested tables, metadata display widgets) and it was easy to do for each case because we had direct control of the HTML and could directly pass the data needed for the various widgets to them. So, with option 1, we’d have to figure out how to make that really easy to do.<br><br>Below is something I just sketched out in the last few minutes to maybe help explain it.

You could alleviate that problem by having services, aka service for headers, service for table batch action, etc.... that could then follow similar to the angular workflow plugin pattern we discussed at the midcycle <a href="https://blueprints.launchpad.net/horizon/+spec/angular-workflow-plugin">https://blueprints.launchpad.net/horizon/+spec/angular-workflow-plugin</a> (Lin, this is how angular does inheritance).<br><br>We would also need to follow up this work by enhancing some of the existing directives. Let's take the action-list directive as an example. Currently, you will have to list those actions out manually, so we would have to enhance it by allowing users to add in their own JSON list and have the directive render the full content. Theoretically, that should get us to a point where you can extend actions, workflows, and possibly even columns.<br><br>Hi Lin,<br><br>Basically, the problem that I am seeing is: we are trading semantic readability, customizability, and ease of LEARNING vs extensibility, complexity, and ease of USE. I agree that we should set a solid example before we let the flood gate open. This is a great discussion, now I'm more resolved to find a pattern that could give us more without the tradeoffs.

In addition, we will have to live with long gettext messages and add eslint ignore rules just to pass it. The flip side is that you do have a simple directive that points to a common template sitting somewhere. It is not that much "easier" to the example below. What we're really doing is defining the same presentation logic, but in the HTML instead. Lastly, I'll bring up the customization again because many products are going to want to customize their tables. They maybe the minority but that doesn't mean we shouldn't support them.<br><br>Option 2:<br><br>table.html<br>------------<br><table ng-controller="table.controller.js as ctrl"><br><thead><br> <tr><br> <action-list><br> <action callback="someFunc" translate>Create</action><br> <action callback="someFunc" translate>Delete</action><br> </action-list><br> </tr><br> <tr><br> <th translate>Column 1</th><br> <th translate>Column 2</th><br> </tr><br></thead><br><tbody><br> <tr ng-repeat="items in ctrl.items"><br> <td>....</td><br> <td><action-list><br> <action callback="someFunc" translate>Edit</action><br> <action callback="someFunc" translate>Delete</action><br> </action-list></td><br> </tr><br></tbody><br></table><br><br>Here, your table.controller.js worries ONLY about data and data manipulation. The presentation logic all resides in the HTML. If I want to add icons in the table header, I can do that easily. Remember that this is plain HTML, this is a lot easier for someone new to come in and learn this than our special horizon-table directive. It is definitely easier to USE, but I would argue that it is harder to learn.<br><br>--------------<br><br>If you compare the two options above, you'll see that all we've really done is move presentation logic from the controller into the HTML. You have to define that logic somewhere, why not in the HTML? This makes it easier to read and know what you're going to see in the browser (something HTML5 spec is evangelizing), and you get the bonus benefit of customization.<br><br>I'd like to point out that we aren't getting rid of directives, we're still using directives them (like <action-list>, <action>, <magic-search>, etc..) in our tables. The pattern is, you build your panels using smaller components instead of having one giant component that encapsulates everything. Of course, there isn't a right or wrong answer, in fact there are two very different implementations of a table directive out there right now:<br><br><a href="http://ng-table.com">http://ng-table.com</a> (more inline with option 1)<br><a href="http://lorenzofox3.github.io/smart-table-website/">http://lorenzofox3.github.io/smart-table-website/</a> (more inline with option 2)<br><br>Basically, what I'm trying to say is: let's build something simple and easy to understand first (small components that we work), then we can build something more complex on top of it so that it easier to use. I don't think there is a right or wrong answer, just two very different ways of thinking and implementation. But if we start with smaller components first, we get the goods of both world. The guys that want to customize will have a way to do it by bypassing the horizon-table directive, and the guys that just want a simple table can use the more complex directive.<br><br>-----Lin Hua Cheng <<a href="mailto:os.lcheng@gmail.com" target="_blank">os.lcheng@gmail.com</a><<a href="mailto:os.lcheng@gmail.com">mailto:os.lcheng@gmail.com</a>>> wrote: -----<br>To: "OpenStack Development Mailing List (not for usage questions)" <<a href="mailto:openstack-dev@lists.openstack.org" target="_blank">openstack-dev@lists.openstack.org</a><<a href="mailto:openstack-dev@lists.openstack.org">mailto:openstack-dev@lists.openstack.org</a>>><br>From: Lin Hua Cheng <<a href="mailto:os.lcheng@gmail.com" target="_blank">os.lcheng@gmail.com</a><<a href="mailto:os.lcheng@gmail.com">mailto:os.lcheng@gmail.com</a>>><br>Date: 08/19/2015 05:15PM<br>Subject: Re: [openstack-dev] [Horizon] Update on Angular Identity work<br><br>Hi Thai,<br><br>Thanks for investigating the two options.<br><br>Option 2 might be better.

Keep some of the presentation related data in the HTML: mainly things like table headers, column definitions, translated texts, etc... I like this approach a bit more because it allow us to read the HTML and know exactly what we are expecting to see. This table.html is compose of smaller directives like hz-table-footer and regular html tags like <th> and <td> etc... I think as we have more of these smaller directives available, we can combine the fragments into one file.<br><br>2. We could create a more general table directive with a common template. This is more inline with what we have currently for legacy. BUT the presentation logic like translations, definitions would now have to reside in the table controller AND we lose the semantic readability part. Doing it this way could potentially introduce more complexity as it now requires people to learn the table directive, which could be very complex if it does not use smaller directives. Another common problem we encountered with this pattern was a lack of customization. In legacy, it was pretty hard to add an icon into a table cell.

There were a lot of template duplications, this clone feature reduces the HTML by a considerable amount. Since this is something we use quite often, it made sense to invest time into improving it.

I believe we have a pretty good pattern setup for tables. The final piece of the puzzle was the patterns for various actions. We have wizard (create user), form (edit user), confirmation dialog (delete user), and actions with no modal dialog (enable user). We wanted a general pattern that would address the requirements mentioned above.
