In this episode, you'll learn about some more advanced active record associations, see a few of the new TailwindUI tables, and we'll wire up a new host/reservations controller. #rails #rubyonrails ## Transcript what's up welcome back we are building clear b b which is a vacation rental marketplace uh we're using ruby on rails and in this episode we're going to use tailwind css to build out our reservations list view so that we can ultimately kind of just like see what upcoming reservations we have that we're going uh to someone else's house and then we can also see reservations on a list that are upcoming for the guests that are going to come stay with us so the first thing we want to do is kind of get the data on the page so if we jump into uh reservations controller in the index we're going to have two lists of things the first is going to be a list of reservations and current user.reservations right now includes all of the reservations where we are going to be a guest so has many reservations where the foreign key is the guest id so if we jump over to the reservation model you'll notice that a reservation belongs to a guest and because we're using the guest id here it's a little bit more sort of it tells you a bit more about the context of what that id refers to instead of just saying user here we want to say guest id so that we're really clear about what role that guest is playing on this reservation because on our reservation we actually have two things we have a guest and we have a host because we want to be explicit about the type of role for the user on this object we also need to specify the class name because the class name is different from the name of the association if the if the we had a class called guest then we wouldn't have to specify the class name but because user is the type that we want to return when someone calls reservation.guest we have to specify the class name here now you'll notice that the reservation right now doesn't actually have a host we're not tracking the id of the host on the reservation instead we're tracking the listing and a listing belongs to a host and so what we want to do now is somehow associate a reservation with a host and so what we can do is we can say that a reservation has one host through the listing model well if we jump to the listing model and we can verify here that we actually do belong to a host and so what that does is that buys us a new association type on the reservation where we can now call dot host and that will find the user object through the related listing of the reservation activerecord is super nice and does all of this for us so if we jump into um rails console and we say like u is user dot or like i don't know r is reservation.last then we can say r dot um host uh is this user so that is the user and we can say r dot guest is another user so the host is wave out c job dev the guest is wave plus guess that's ejevdev but you kind of get the idea so now we have that two-way association on the reservation object itself so we can go back to the reservations controller that's the first type of reservation let's head into the reservations index and build this out so in the first header i think we want to say something like your upcoming trips or something and by default this will be a table of all the trips for this user now tailwind ui just released a bunch of new tables which are pretty cool so i thought we would just grab one of those and use that as our table view for our list of upcoming reservations so i'm just going to grab the html for this there's actually quite a bit here but we'll figure it out okay so it looks like at the top let's see so users i think we want that to be your upcoming trips um your upcoming trips and then a list of all the users in your account okay i don't actually think we need that p tag and then we don't need a button um and we'll just remove this thing i know it's just going to be like a really basic ui and then for each row in the table we want to iterate over at reservations that each do reservation and we're gonna spit out these rows keeping it super scrappy just using erb to print out stuff so we have this logged in user this authenticated user has two trips that are upcoming we have no idea what they are because right now we're just plopping in some default text from from the copy all right so what i think we want to do is print out where we're going that's like really important so let's say reservation.listing.title we refresh the page so we're going to a a listing called find me on the map in california and this is going to be let's make this a link to that place so we're going to say reservation path reservation and now we can click on these and it'll bring us to the reservation detail page and then um in terms of the let's see what else what else might we want to care about here we definitely want some sort of like check-in and checkout date so we can print out the reservation.start date and maybe we also print out the reservation end date um okay preservation.end date and that'll give us a start and end date maybe we also want to know like um the status of the reservation because uh it could be pending or booked or whatever so reservation.status and okay maybe this edit maybe this edit link is actually just going to be like another link that lets you view the listing so reservation path for the reservation that's what we'll make the the link tag go to and we'll just say view and this is looking pretty good we need to change our headers here so this is going to be like listing and then like check in and check out and the status and then for now yeah we'll say that this is just to view okay so now we have our listing we have a check in we have a checkout we have a view button when we click on it we see the reservation all of that is looking really good and i'm happy with this that is our upcoming trips now let's talk about the trips where we're going to host someone else that's going to be a different table so what i think we want to do is grab because it might be different data i'm actually just going to copy and paste this for now and this might seem kind of crazy and it's not dry and whatever but it actually makes it a lot easier if we want to customize like your hosted trips or something or like your upcoming or like you are hosting these guests you are hosting these guests or something i don't know um and instead of uh reservations instead of iterating over reservations here we want to iterate over host reservations that's going to be another collection that we create inside of the reservations controller host reservations is going to be current user.host reservations now the current user doesn't actually have this association so this is going to crash and burn right here but what we want to do is somehow figure out what are all of the reservations where we are going to be the host so if we go look at the user model again we want to have some association called like has many host reservations now because the name of the association is not reservation we need to specify the class name as reservation and because a reservation does not directly relate back to a user so recall that a reservation the reservation isn't directly related back to a host it's through and through another association what we want to do is actually say that we have many host reservations through listings because a listing should have many reservations so a listing has many reservations all right so then back over here we should be able to say through listings now the problem with this is that yeah and uh github co-pilot is already telling us what we need to do and that is add this uh well actually let's just do it so we have to say source reservations because if we look at that listing model again the listing model doesn't have any associations called host reservations exactly so instead what we need to do is specify which named association on the listing model we're going through that we want to use that should return reservation classes when we call host reservations all right so let's take a look so if we refresh this page now we have some you're hosting these guests so this is like who we're gonna host and right now we actually don't even have any so if we go back to the reservation index here we can just hide this entire thing if um like i don't know if there's host reservations that empty only show this if the host reservations are not empty uh okay that's i don't know that's pretty good um now we'll only see these reservations okay so that is i don't know i'm pretty happy with that let's log out and then log back in as another user that does have hosted reservations so wave at cjib.dev and if we go to reservations view this is all of our upcoming trips we have a lot with this test user and we also have a bunch that we are hosting so we are hosting these two with that other guest that's upcoming so one thing that might be nice is for the trips that we're hosting for guests we want to know the listing but we also want to know the guest so let's add another thing here that has the guest name and i think we might eventually have like a guest path or something like that to see the details of the guest so sometimes we'll see you know like is their identity verified and do they have all of the right stuff that they're supposed to have in order to come visit um so what does a guest have user does a user what does the user have a user should have an email at least right so reservation.guest.email so r uh yeah r.gast.email okay did i hide something here what's going on reservation.guest.email it's printed out uh okay let's see here so this is gonna be guest there it goes i don't know what's going on with that okay so now we have this guest view that has who's coming uh at least their email address we don't really we don't collect the name of the guest yet right now but we will eventually so now we're able to see the email of the guest when they're coming et cetera et cetera et cetera we could probably put like a gravatar image of the guest or whatever but for now this is fine um and right so when it's a hosted reservation we need to be able to see the detail view and the role is going to be a little bit different when we're a host we might have buttons like cancel the reservation or modify or send a discount or things like that whereas if you're a guest you're just gonna see like you'll just see sort of like the message view how do i check in and what are the you know codes and stuff like that so we probably want different a completely different view so like host reservations with that id um so why don't we just quickly uh make that so rails g controller host reservations and that's going to have a show page and then we can jump into our routes and make sure that we have our host we'll say host resources reservations and then the this is going to like only uh show for now host reservations controller and here we'll say like at reservation is equal to current user.host reservations.find params id and we should see something here okay so then the host uh reservation show we can just we'll just copy what we have in reservations show for now reservation show oops and cool so now we have the listing we have a little bit of information we probably also want like yeah uh h3 i don't know reserve reservation.guest.email etc okay so now we can see who's coming and where they're coming if we want to dig into the json we can see the start date end date etc but now we can go back to reservations we can look at where we're going or we can look at people who are coming to visit us and let's see can't find reservations oh right okay so now we need to go back to our reservations index and the ones down here we want these to be host reservation path so that we are linking to the right uh view for those so if we go back to the list of reservations and click on one down here it should okay brings us to the host host reservation namespace all right that is a fun little breakdown using tailwind css tailwind ui tables um doing a little bit of active records stuff in the next episode we will talk about messaging i think we're going to build out some two-way messaging where we can kind of chat between the host and the guest and that should be pretty fun so we will leave it at that thanks so much for watching and uh yeah we'll see in the next one [Music] you --- [Back to all videos](https://www.cjav.dev/videos) --- ## Hey Agent,
