Transcript what's up welcome back in this episode you're going to see all about building out a store with a custom sub domain so we can list out the products as we build out this creator platform so let's jump into it we're using ruby on rails and the first thing we're going to do is generate a store model so we're going to say rails g model store and it's going to have a let's see probably a sub domain and maybe also a domain and potentially some primary color maybe a secondary color and each store is going to be related to a given user and for now we're just going to have a one-to-one mapping between users and stores so we're gonna say railsdb migrate now for each store that we create and create a subdomain what we wanna do is route based on those subdomains so i'm gonna open up our routes here we're gonna talk about some constraints constraints and we're going to pass in a class name here of domain constraint and that's going to allow us to set up a bunch of different routes that are based on a specific domain now in order to create this class we actually have to go make this manually so i'm going to open up lib and add constraints and domain constraint that rb and inside there will create our new class domain constraint and this is going to have a method called matches and it is going to accept the request and we're going to look at the request and decide if there's a store where the domain matches the request.domain or where the site the site's subdomain matches the domain and then we can say like if this exists then it passes our domain constraint now what's nice about this is we can just pass the class name instead of having to like pass in an instance of the class and that should give us a little bit of routing now in order to use this domain constraint class this is one of the rare times in rails where we actually need to require something so here we're going to say constraints slash domain constraint not admin constraint domain constraint and we should be good to go so in order to test this out i'm going to say rails g controller stores slash products now what i want to do is create a namespace called stores and under that namespace i'll create a bunch of controllers and methods and actions that are related to these storefronts so we're going to create this stores module and inside of that stores module we're going to start putting stuff the reason we can't call this a store module singular is because then it would conflict with the name of the model so we're going to say generate this controller all right so we were able to generate this products controller so now we can go back into routes and inside of our constraints here we want to say scope and we want to scope this to the module that is the stores module and inside of the stores module we're going to have resources products okay so this this controller is going to be inside of a a namespace controller let me show you what that looks like in the directory structure so if we go to app controllers notice that we now have this stores directory and in there we have a products controller with this stores module namespace at the beginning so we're actually going to remove that and create module stores and right now we're inheriting from application controller but every single controller that works with a store i want to inherit from a different controller so i'm going to create a new controller here called the stores controller and this is going to be sort of our parent controller we're going to say class stores controller that's going to inherit from application controller and this is going to have a couple different methods one is going to be that before any action that happens on any controller we're going to set the store so any action that happens on any controller that inherits from store controller we're going to set the store and this is going to create a store by saying store is equal to store dot where actually this is this the same thing as the domain constraint so let's go back to our domain constraint we should probably actually move this down into um a model method yeah so let's go over here and make a method on the store called find by request and then we're just gonna say do these two things and that should be good okay so it's gonna be where so this will be self dot so now we should be able to just say self dot um or store dot find by request and pass in the request find by request pass in the request and then say dot exists and if so then we are going to have a matches but also in our stores controller we should have a thing where we can just do like store.find by request and pass in the request and that is going to set our store now to make this a little faster we'll memoize it and now this action will happen anytime any controller that inherits from the storage controller executes in action wrap it in a little module here and we're going to change our products controller so that it inherits from the store's controller so we'll make a little uh index method here we're going to say products is store.products we'll make a show method and that's going to say at product is at store.products.find params id this should be like a really basic starter kit let's also open up the rails console and find our first user and say you like store is going to be udot create store bang and we want to pass in the primary secondary let's just say the sub domain for now is called test okay you create store undefined method oh you know what do we have on the user model did we add okay so a user has one store and a store belongs to a user and has many products through the user all right so that should work so u is user.first u dot create store um [Music] with all of this that should give us back a store now we have a store object that has the subdomain test let's also try out stored store dot i guess find by request we'd have to build up something like request.new with subdomain test i don't know if that actually works yeah okay so uh for now let's just let's just assume this thing is working and go test it out so here i'm using lvh.me instead of localhost that is a domain that will also resolve to your local machine and the nice thing about that is it lets us test out these subdomain routing and so we're getting an error here it says you need to sign in or sign up before continuing but in our products controller that we just created we don't have anything that's requiring people to log in right and so what might be happening is our other products controller that the admins use is authenticating that user so let's go back to our routes and take a look here so inside of our constraints we're having we have this domain constraint and i wonder if our domain constraint is actually not working so let's go to our store model and add a method here that's going to actually let's just say like okay uh puts like finding by request and then we're going to say p that results so that we can tell whether or not it found it as it goes and then we can go look at the server logs and if we come here and refresh the page so we have a get for slash oh you know what it should be slash products slash slash products okay so that's great all right so now we are hitting a products controller and this is for at store.products so undefined method products for active record relation ah so inside of the store controller find by request ah right now find by request just returning a full active record relation so we want we only want this to return the first result so let's refresh this and undefined method exists on the request yeah so if we say store dot find by request that gives us back a single store so then we should be able to just say like as long as it's not nil so let's go to our domain constraint and say as long as this is not nil we might need to restart the server since we're changing that part of the code okay stores products controller index is missing a template fantastic all right so now what we can do is we can go into um stores our views for the stores products index.html.erb and here we'll just print out at products.org and okay great we're seeing the json spit out but something that's a little bit funky is that we're still also seeing this top banner so let's create a new layout that is specific to our storefronts so i'm just going to copy application html and call it stores.html and in here we will just like yield uh and then we'll say we'll come back and style this a little bit later now we need to go to our stores controller and set this as the layout for all controllers that inherit from the stores controller so now we've got some json spitting out when we go to test.lvh.me now what ideally instead of having to go to like slash products it would be nice if we could go directly to the root so let's go update our routes one more time and we're gonna say root and i think previously i was just like not doing the right index action so invalid root name you already have the name root used so now we'd have to say like as store root okay let's see if that works all right so this is still using the why is that using the root let's look at the server logs yeah this is processing it's being processed by the static pages controller oh okay so what we need to do is move this route definition below our domain constraint i think so so we'll come back over here refresh and now at the root we're seeing the list of products so ideally this is some sort of fancy list of products or like a product landing page of a storefront and we are going to like render all of the products in a nice beautiful way but at this point we've got our stores we're able to um render our or we have like domain routing based on the stores i guess another thing we want to do is back at sort of like the dashboard or the management page for these stores once we're logged in we should be able to create stores so if we go to our dashboard what we want to do is come over here and add a new tab called stores which allows us to create stores so let's do that now i'm just going to say rails g controller stores it's going to have an index yeah index and show now is this going to conflict this might actually conflict with the naming we'll have to see so um the naming of this controller might conflict with that name spacing but we'll have to play around so we create this new stores controller and we also are going to want like a new page so if we go to our routes we should have this new we'll have a new resources stores and go to our stores controller and in here we should have a new method that allows us to create a new store it's like current user.store actually um let's just make it edit we're going to say at store is current user.store we don't need an index route we only need a show route because we are remember we only have one store per current user so current user.store and then we'll have um when the user is first created we'll just automatically create a store for them every single time and we'll call that good so private store params and we want to permit what do we want to permit the domain domain subdomain primary color secondary color okay so let's go create some of this stuff so we're going to have a store show page so stores we actually want to make this let's just make this the new route or the edit route the edit wrap okay all right let's go back and find a nice form from uh tailwind ui we're going to go to application ui forms form layouts again we want to use the stacked layout so we're just going to copy all of that paste it in our form is going to go to now it's going to send an update request to the store path for at store and the method is going to be post but really the method is going to be patch and the authenticity token we need and this looks like it didn't actually set inside of the type all right so what do we want our store thing to look like i guess we also want to update our application helper so that we have a new route here we're going to call it store and we need to go to our routes and update this so that it just is singular resource resource store so we're going to refresh this go to your store page okay here we go stores show that's great now we go to stores show and this is going to have like i don't know at store.json or to json we'll come back and style this later the one that matters the most is this edit page so let's add a link to edit store path at store okay so we can click on or maybe it's just edit store path edit there we go okay so this is our edit view now what's confusing is that we see this edit view but the layout for the dashboard is missing and that's because we have our stro our stores controller here but there's also a stores controller inside of the storage controller namespace so i'm going to rename this one to store base controller so that we don't have this conflict so we're going to call that the store base controller and our store products now needs to inherit from store base controller and now we should not have these same layout issues stores controller i'm from the future and i'm editing this video where i'm confused about what's going on with these layouts so i did some digging while after i finished the video and it turns out this is because of nested layouts so because i named the stores layout stores and then we have the stores controller even at the top level it is assuming that that is a sort of sub layout underneath application html erb so in a second i'm going to fix this problem in the video by just hard coding the layout for the like top level stores controller to be application but no this is something about nested layouts we're going to do a follow-up episode about nested layouts in a future episode so just sit tight uh but yeah the the naming conflicts here were confusing and i'd never actually use nested layouts so that is what happened nested layouts okay so my sense is that the layout is being generated yeah it's using the stores layout controller even though we want it to use a different layout so one way we could do this is just say layout application and force it um so that will add this back in but i think yeah because we're using the same naming everywhere the the naming is definitely starting to conflict so that's all right though all right so inside of our store edit what we want to do is update this so that we have um okay so this should be what do we want this to be this is going to be the domains or something like i don't know your store where you sell digital products okay so then this is going to be yeah so username instead of username we're going to set um this to domain or subdomain subdomain g and we're actually going to leave out domain like not let people edit domains for now because that's going to be a little bit fancier and we're going to need some more some more tooling to use that so in order for us to render out the subdomain nicely so that they can see sort of the top level thing it would be nice if we had some domain that we could use as like the second part of this url right so that showed kind of like what is your sub domain x and then it would tell them like okay dot something so let's just update this to be uh i don't know like dot creators dot dev okay so if we refresh now we see dot creators.dev but the rounding is all wrong right we like took one end of the train and flipped it around and pointed on the other end so we want to change we want to update the routing this is part of tailwind css so here on the on the input box we want this to be with full rounded none rounded left medium and then on the span we want this to be rounded right medium and if we refresh this okay so now it's kind of working but it looks like the end of that like the tail end of it is being cut off a little bit so i'm guessing that is because the border right yeah border so now we want the border left to be zero and i think this might be good okay so border right now is showing we have our sub domain test two okay so the other thing is that if someone attempts to use a subdomain that's already taken we should let them know that they can't have that subdomain so one thing we could do is like as they're typing go and request the list of subdomains and see if it's available and not let them have it otherwise but we can we'll save that for a little bit later okay the other thing we want to do here is the name here should be store subdomain and then we also want to set a value because theoretically this is already set up for you right so this is the subdomain that this current user has already set up is test so we could enter a bunch of about information photos cover photos etc but for now we're just going to delete the rest of these inputs so that we just have one single kind of like set of inputs at the top here and then a button to save we don't need a button to cancel and then also what we want to do is add some inputs for colors so what we can do is grab this and say that we want a color so we're going to change subdomain to primary color and then the input type is going to be color and instead of sub domain here we're going to call this color and that is now a color input we don't need that span though uh anymore and i think let's see all right so that looks a little bit funky let's style this manually so we have our primary color we are going to just start from scratch and remove all of the classes so we can see what it looks like without anything and it's honestly not that bad the thing that's weird is that this is still flex and has a shadow okay so that's gone so that's actually pretty good let's make that just say primary color and call that good for now and then we'll change this up or we'll duplicate this and create a new one called secondary color okay all right okay primary color secondary color so people can come in and kind of like pick their colors as they wish now uh the top of this section still has this gray border so let's remove that gray border that is hanging out on top so we're going to remove all of that and also remove it here okay so your store when you sell digital products where you sell digital products okay so now we have our sub domain we've got a primary and a secondary color picker one thing we could do is pre-fill those with whatever is stored already but for now let's just let people kind of pick and we should go from there all right so we've got a primary color secondary color if we click on save that should submit an update request and it looks like it did and it should redirect us back to the show and it did so we're good we can update our color to a different color update our secondary color to a different color and then hit save and those look like they updated so that is working really well all right so now we have our stores we can edit them we can update them we've got primary color secondary colors that is all working really great so i think we're going to call it good there and then in the next episode we'll continue on building out our store and styling our products pages thanks so much for watching and we'll see in the next one [Music] --- [Back to all videos](https://www.cjav.dev/videos) --- ## Hey Agent, thanks for visiting!
