build out a list view for our orders so that we can see what we've purchased now that we can log back in as a customer if you recall in the last episode We Built This Magic Link login when you uh enter your email you receive this email that has a login link that's just magic uh Magic link authentication and then we landed on this orders page which doesn't actually have any content so let's take a look first at the database and see how we might model our orders so if we look at the schema for the database we have these customer objects and inside of the customer uh instead of customers or next to customers we have this object called customer products that's the join table between a customer and the product they purchased we called it customer products but really the name might actually make more sense as orders so I'm not going to rename it at this point but I am going to just consider a customer product sort of a at least a reference to an order that also gives us reference to the checkout session ID we're going to have all the information about the payment and whether it was successful or not we also have reference to the internal product and the internal customer so it is kind of like this nice join table that tells us information about what was purchased so we already have this orders controller and right now the index is just rendering at this plain thing so let's say uh our orders are current customer Dot customer products dot order uh by we're gonna order them descending and then inside of our orders index we want to build out this view so that it actually has like a nice a nice look and feel to it so we're going to grab the same sort of header that we've got over in our products view we're going to use that inside of the index here and I think we also want to have a table so we're going to use Tailwind UI again and we're going to grab just this simple table here we're going to just take all the HTML for that and we will drop it in to the top and we don't actually need this header because we're going to keep it nice and simple so in order to show or like to when we're talking about rendering our list of orders here we're going to iterate over at orders and print out our rows of our table for each order in the database associated with this customer so the first in the First Column let's put in perhaps we put in like you know the the ID of the order order dot uh ID I don't know if that's the actual order ID that we want to show people or not I think we want to actually maybe show them the checkout session or the payment intent I don't know um then next let's show the product name and finally we'll just have a view button that will users or bring customers to some detail View for the order this is going to be the order path for the order and let's take a look at what we've got so this is our orders page now so we have some list of orders it has an ID tells us what we purchased and we can click on view the headers are a little uh incorrect here so we'll say product we could even put like an image of the product in here because we do have that product image but for now we'll call that good okay so for the show page on the order this is where we want to show sort of maybe a little bit more detail about what was purchased so this is going to be the product and then maybe the photo of the product and then we want to list all of the attachments that users can download so here what we might do is let's go build out um our order show page and inside of that order show page we're going to start with you know a similar header here and this is going to say maybe order at order.id and then we'll have some details about the order so before we can even render this we need to go back to our orders controller and create a new method here for our order current customer current blah blah okay so now we see this is for order ID number 23. all right so I think on the left side we want to show the image of the product so let's actually start from the product Show view and then we'll sort of edit it to make sense for the customer so if we refresh the page now we don't actually have a product and we can change that by going to our orders controller and grabbing reference to the product is at order.product refresh the page okay so this is pretty close to what this is what the the Creator sees as they are editing and creating their product but we can do something very similar here where instead of naming the or showing the views we can just have like download buttons and then we'll say the name of the attachment and uh we'll yeah so we need to modify this a little bit so at the top or on the left pane we're showing that product image and then we're going to have a list of all the attachments that you can download okay and let's see here oops we changed the wrong one so here a list of the attachments that you can download okay so now this is a list of the attachments you can download we don't want views because we don't want the customer to know how many people have seen this and then instead of this edit button we're going to have a download button and our download button is not going to use the default sort of um active storage download tools and that's because we don't want people sharing these download links with each other so instead we're going to share a or this download link is going to be sort of like almost a proxy or we're going to use the controller as a way to just render out the raw blob for the object and that's because we don't want someone just to like right click and say copy link as and then share it with their friends and then they can download it directly from AWS so instead we're going to make this download link actually go to orders or maybe to like some attachments route or something so maybe we can call this like attachments path for attachment and that will go to a controller action inside of the attachments controller that will require that the customer is logged in with at least with their uh their magic their magic link authentication so this attachments path doesn't exist because I don't know if we have an attachments controller yet so let's look at our controllers inside of the uh the stores controller it does not so let's go create an attachments controller inside of the stores controller rails G controller stores attachments okay stores attachments controller this is going to inherit from the store based controller and it's going to have a a requirement that you're authenticated as a customer so again if we look at like the orders controller this is going to authenticate the customer here and here we'll just say like show and the show route we'll just we'll find the attachment and then we're going to send the raw attachment sort of like GitHub copilot thinks we might okay so then does this work no okay so inside of our routes we have to add a new route for attachments inside of here resources attachments okay all right so now we have at least we have this like download link but the uh yeah so it says the attack the index action could not be found right okay so instead of um I I did this incorrectly so back in our order show page this is going to be to the attachment path um attachment singular okay so now that should go to the right thing okay and then the the show route is missing a template for the request okay cool but that that's like getting us pretty close so let's also remove this form to add an attachment like it doesn't make sense for a customer to be adding attachments so that is fine to remove and then this one doesn't have a name and I think it was actually like a broken attachment but whatever so now what we can do is we can say uh let's go update our attachments controller so that it will download the file so we're going to say at attachment is current customer dot attachment stuff find paramsid let's see so does the customer have reference to their attachments it does okay so it has products through customer products and then a product has many attachments so we can say it has many attachments through products that's going to be quite the join but it should work just fine all right so now for now we'll just render the Json of the attachment so that we can see that this is working as expected okay this is cool now we've got the name of the attachment we have um some details this is also where we will log that the current customer is viewing this attachment so we'll kind of keep track of how many times each individual customer is actually like downloading their files so maybe you're now wondering like how do we actually get the raw file right and so if we look at attachments if we actually let's let's open up a rails console attachment.last so this is going to have a file on it and that file is an active storage attachment and one of the methods that are available is called download and that will give us back the actual just like blob or like the raw binary for the file which is going to work just perfect for our use case because what we can say here is instead of render we're just going to say send data that is like a very raw or like it's a little bit of a lower level method instead of render or redirect and send data allows us to just pass in a blob as the first argument so we're going to say attachment.file.download and then we can also give it a file name if we wanted so maybe we can just say like file so each file when when it's uploaded is going to have a file name I don't know if this is what creators will ultimately want but we could do this file.file name there's a bunch of different methods here too so we can say file dot file name um so that tells us what the file name is but that gives us back this object this active storage file name object and so what we need to do is actually convert that to string if we want to use that as the file name.2s okay so now when we go to the show route for attachments so if we come back here refresh the page now if I click on download you'll see that the the ebook is actually downloaded as a file so what's cool about this is if the customer is logged out so we'll just clear our cookies here and try to refresh this page so we're not able to we're not logged in right now but if we try to go directly to attachments 2 then we're not able to download the files so this is one way that we're sort of securing those files so that people have to at least do a little bit of authentication to see those okay so now we've got a full working system right so users can or customers and customers can log in to the website where they purchased their product they can view the products that they've purchased and they can download the content of those ebooks or audiobooks or whatever is being sold as part of that product so now we have sort of a pretty complete workflow however I think it would be even better if we had a way to email the customer when a brand new product is available that they've purchased and let them know they can come to this page and we'll sort of embed a little bit of information about how they can log in ETC so let's do that in the next episode 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
