00:01 Let's add a bookable time to one of our existing cages.
00:05 We were able to register cages and list them.
00:07 Now let's make them available for snakes to stay in.
00:12 We're going to work on this update availability
00:14 that we did here.
00:15 We've got our requirement that you have to have an account
00:18 because they're your cages,
00:20 whose cages you're going to manage, things like that.
00:23 And we're going to just print out the list cages.
00:25 I've changed that slightly so it has a number.
00:27 I'll show you really quick.
00:29 I'm using enumerate in an index.
00:32 It says one, two, three instead of star, star, star
00:34 because we want to ask like,
00:35 "hey, what cage do you want to work with?"
00:38 We're going to add that here
00:40 and just for the sake of time I'm just going to paste that.
00:42 So it's going to say, "What cage do you want?"
00:45 Either you can cancel or it's going to parse that
00:47 into an integer
00:48 and then we're going to work with a particular cage.
00:51 Let's go down here and say "selected_cage"
00:55 Oh, first we need the cages.
00:56 Let's say "cages = " we'll just use our service again.
01:00 Get the cages for "state.active_account"
01:05 We'll go down here and say "cages[cage_number-1]
01:10 Because we're showing it to them one, two, three.
01:11 We got to convert that back to zero base.
01:15 Once we've gotten our cage set, we need to get the dates.
01:18 We've selected this cage.
01:19 We'll say the name that you're going to work with.
01:20 We're going to say enter date, year, month, day
01:24 that you'd like to start this available time slot on
01:27 and for how many days.
01:28 I want to start a particular date
01:30 and make that available for five days.
01:34 We're using this thing called parser.
01:37 That comes from "dateutil"
01:39 so python-dateutil is the module name.
01:41 It's in the requirements already.
01:43 Parser is a really sweet way to parse date times.
01:47 It has many, many different formats it understands.
01:50 We're going to use that
01:51 instead of the built-in date-time parsing.
01:53 Once we have this, we just need to go and use our service
01:56 and write another data access method.
01:58 We'll say "svc.add_available_date"
02:02 What are we going to pass?
02:02 We have to have the account.
02:03 Let's say active account there.
02:07 Select the cage that we're going to add it to.
02:09 We have to have the start date and the days.
02:13 Let's go ahead and say "state.reload_account"
02:16 This might change the account.
02:19 Then we want to have a little success message like
02:22 hey, good job.
02:26 And F String this.
02:32 Now we're down to just pure data access and MOGO,
02:35 the interesting part, right?
02:37 Let's go have PyCharm add that function.
02:41 We'll have a few things here.
02:43 This is going to be an owner.
02:48 Cage, date, time.
02:58 And an "int" and it's going to return nothing.
03:01 This looks great.
03:02 Remember what we're adding here is actually a booking.
03:06 Bookings are not top-level items.
03:08 But we'll go and create one to get started.
03:10 I'm going to say booking.
03:11 It's a booking like so.
03:14 We just got to set the properties.
03:17 This one we got to do a tiny bit of math here.
03:20 We'll say "start_date + timedelta"
03:30 Now we want to change the cage.
03:32 The way it's working probably is fine.
03:34 Just change the cage and call save.
03:36 But I want to make sure that we absolutely are working
03:39 with what's in the database.
03:40 So I'll say "cage = "
03:44 Actually we can just look it up here, I think.
03:46 I'm not sure if we need it again.
03:48 We'll just say "cage.objects(id=cage.id).first()"
03:55 Then we're going to go over here, select the cage that was.
03:59 Let's check that here.
04:03 Again remember the bookings are not top-level items.
04:05 They live inside of the cages.
04:07 Here we're going to append the booking here
04:09 and we call save on the cage not on the booking object.
04:15 It doesn't live on its own, it lives inside the cages.
04:20 Here we can return a cage, I suppose, if we want.
04:23 Here's kind of the updated cage.
04:25 We could even tell consumers that that happens.
04:30 I guess we don't need our active account here, do we?
04:32 So we can go ahead and drop that.
04:34 Let's just do a quick clean-up here, get rid of this.
04:37 We're not doing that, nothing changes there.
04:39 Okay, great.
04:40 It looks like we can probably add some time.
04:43 Let's go and try to test this out here.
04:46 Going to be the host, we need a log in.
04:49 Let's see our cages.
04:51 We've got these two, let's update the cage availability.
04:54 The large boa constrictor one is available
04:57 so that's going to be number two.
04:58 Great, we've selected it.
05:00 This is going to be 2018/01/01.
05:06 Brand new year, cages available.
05:09 Let's say that's for five days.
05:11 Great, a date was added.
05:12 Let's add one more.
05:16 Cool, now if we list our cages,
05:18 you can see our low large boa constrictor cage
05:21 now has two available bookings.
05:23 It has this time for five days and that time for ten days,
05:26 And neither of them are booked
05:28 because no guests have come along and actually booked it.
05:30 But it's available and now they can go and ask,
05:34 hey what cages are available for my snake?
05:37 When they ask, this large boa cage should come up.
05:40 Maybe we'll make a little side money
05:42 while our boa constrictor is not using it.
