Horizontal Select and TabularInline

Now that we know how to group fields together into field sets, 0:00 let's learn a new way to change the way the fields look on the admin site. 0:04 Let's replace a drop down menu with a selection of radio buttons. 0:08 And then change some fields from stacking on top of each other to being in 0:13 a more tabular format. 0:17 First, let's replace the drop down menu for 0:19 Quizzes in the questions model with some radio buttons. 0:22 So what we're doing is replacing this drop down menu right here with a couple of 0:26 radio buttons instead. 0:31 And doing that is actually really simple. 0:33 So, all we do is scroll down here to our QuestionAdmin, 0:36 and we add this field called radio_fields. 0:42 And then we set it equal to a dictionary. 0:46 Now, the key is the name of the field in our model that we want to change, 0:49 in this case, quiz. 0:54 And then the value is going to be admin.HORIZONTAL in all caps. 0:55 This displays the options horizontally instead of vertically or 1:02 stacked on top of each other. 1:06 Since the user can only select one, 1:08 that means the options get displayed as radio buttons. 1:10 So now, whenever we go over here and 1:14 refresh, you can see those radio buttons instead. 1:16 This is especially handy if you have a field in your model that should only 1:21 have a few answer choices. 1:25 For us, those fields are which quiz a question should go with, and, 1:27 which course a quiz should go with. 1:31 The number of selections we have to choose from will grow over time, so 1:34 we might wanna stick with the drop down menu for now, but 1:38 this way you know about the option. 1:42 Now, let's go back to the list view. 1:44 Notice that the horizontal select option also affects 1:47 the list view if that field is editable in the list view. 1:51 For our last trick in this video, let's talk about tabular inline. 1:56 Tabular inline is an alternative to stacked inline. 2:01 You've already seen stacked inline. 2:05 It's how the text inline, quiz inline, and answer inline classes are set up. 2:07 So, for example, if we go into these true, false questions, you can see 2:13 that the Order, Text and then the Correct are all stacked on top of each other. 2:18 That's stacked inline. 2:24 Now, this is fine for a model like text, but for answers, 2:26 this one, it might be better to have things lined up across like a table. 2:30 Hence the name, tabular inline. 2:35 Can you guess where we're going with this? 2:38 That's right. 2:41 All we need to do, is make answer inline inherit from 2:42 admin.TabularInline instead of admin.StackedInline. 2:47 So we just change this to Tabular. 2:53 Refresh our page, awesome. 2:57 Now you can easily see all of the answers you've got for this question and 3:01 which one is correct. 3:05 It's much more readable. 3:07 Great work. 3:09 Now you know how to change the layout of the detail page, 3:10 including how to introduce a horizontal select as opposed to a drop down menu. 3:13 And how to change the presentation to stackedInline to tabularInline. 3:18 This will make changing information in your model much more intuitive. 3:23 Before you go on to the next video, can you think of any other models that might 3:28 benefit from some of the changes you've learned to make? 3:31
