to talk about a couple of settings that i like to configure so that it works with turbo we're going to build out our own custom views with tailwind it should be pretty fun so let's get started i'm going to say bundle add devise that's going to add the gem to our gem file it's also going to run bundle install next thing we're going to do is run rails g device colon install this sets up the initializer and some local localization for us and it also prints out some instructions so we want to copy this action mailer default thing and drop that into development.rb if we haven't already i like to drop it right after this mailer section because it is part of the action mailer settings it's been that way for a really long time we've already got a root route based on the previous episode the next thing we want to do is add these flash notices to our application html erb you could put those wherever really but for now we'll just put them here like suggested okay and then finally we're going to run rails g device views so that we have access to a bunch of different templates that we can edit if we need to customize any of the views which we're gonna do all right so at this point we have sort of all of the device stuff set up to work with the device gem but we haven't actually set up a model so at this point we need to store users in the database so that we can authenticate with them so we're going to say railsg model user and i'm not going to add any attributes to it at this point we're just going to create a new table in the database called users it's going to have some timestamps but for now it's just going to be a model so we'll say railsdb migrate and that's going to migrate the database and add those users to the database okay next thing we want to do is say rails g device users and that's going to generate a migration that will attach a bunch of authentication fields to the users table so let's open up that migration take a look so here we're changing the users table we're adding email an encrypted password we're also adding some recovery information if we want to we can uncomment a bunch of different features of devise we can make it trackable and or confirmable and or lockable etc so what i'm going to do is just make it trackable and then we'll say rails db migrate that's going to migrate the database make those changes to the users table we also need to go check out our routes file so inside of routes this device for helper method was added calling out users so now we're going to have this new section of of the of our routes or this new set of routes that is related to authenticating with users resetting their password doing a whole bunch of stuff with users all right so now at this point we should be able to jump over to localhost 3000 and we see this undefined method for devise whatever that's because we need to restart our server after we add new gems so we're restarting the server here we'll come back refresh the page and we don't actually see anything about logging in or logging out but we can go directly to law to figure out what our routes are so we see a whole bunch of user routes so one here one here is going to be called users sign up so if we just look at the users routes we're going to find one here that says sign up this is the new registration path so if we go to directly to users sign up we're going to see this page this is where we can log in or this is i'm sorry this is where we can create and register a brand new account inside of rails i'm going to open up tailwind ui and we're going to use tailwind ui's components for our registration page so i'm going to say sign up and so under the forms component in tailwind ui there's a sign in registration note that tailwind ui is a paid this is a paid product you can sign up and i've used the components from tailwind ui a ton so here we're going to just copy all of the html from this simple card for registering um for your account now what we can do is go over to the views let's actually take a look here so inside of the views for devise they have several different directories here that are going to help us with confirmations or mailers that are going to be sent password resetting registration or sessions so the new template or the new view for the sign up route is where we're going to find the code for the registration now this is using form 4 and my hot take is that using form helpers makes it more challenging to use and this is a great example of why so right here what i actually want to do is i'm just going to copy all of the html for this sign in form and drop it in now i don't want to have to figure out what all of the form helpers are in order to get this form to work with this tailwind thing that i'm adding instead what i want to do is i just want to go directly to the html form make a small change that's going to be related to the action here and i want it to just work right i don't want to have to modify all of the html that i just imported so that it works with these form helpers so but we do need to do a little bit of investigation in terms of what features this existing form from devise we need to carry over into our new form so one thing we're going to do is we're just going to remove or continue with in all of the social buttons at the bottom so i'm going to say this or continue with we're going to remove this entire div and all of this stuff at the bottom i think maybe that was a little too aggressive here we're just going to grab that and go straight down until we find the div that we need to remove okay now if we refresh the page we don't see that stuff at the bottom all right we're getting closer the the original device form has three inputs there's password and password confirmation so we're going to need another input for password here so i'm just going to grab the entire div for password and drop it in and this will be our password confirmation uh field so we're just going to say this is a label for password confirmation and or just password confirm and then we're gonna figure out what the name is later and then here we can just say you know confirm password and that should work just fine so now we have three fields and those should match what we see up here if we inspect this form that's generated by that form helper we'll see that inside of this we're seeing the action is slash users and the method is post so inside of our form we want to use again slash users and the method is post so this is important and that's going to be where our form is now we also have this hidden input this is one of the things that form helpers do give you is the authenticity token they protect you from csrf etc etc but you can just add an input that is type hidden and has the value form authenticity token and you'll be just as safe when it comes to csrf right okay the next thing that we want to do here is figure out what the names are on these input boxes so the input here the name is important because this is going to be the key for setting the params correctly so that it works and plays nicely with device so the name here is user with the email being passed inside of that hash so here on our email input i'm going to go to the name and add user with square brackets around it and the same thing with password user password now the name for password confirmation is going to be something different so we're going to inspect that jump down here user password confirmation so this is going to be for our final setting here user password confirmation and that should be good to go okay we refresh the page here at this point i think we should be in a good place to populate our form so we're going to enter in i don't know test at example dot com password password now notice that our forgot password button isn't going to work yet and also this sign up for your free trial isn't going to work yet but we should be able to at least sign up okay if you see this error message undefined user url for device registrations controller this is most likely because we have not set up devise navigation to support turbo so by default all these forms if we don't disable turbo it is going to use turbo by default so what we can do is we can go to our initializer for device and in the navigational formats we want to allow this new turbo stream as a format as a navigational format because we're changing an initializer we want to restart the server and we'll go back to users sign up slash users sign up and we're going to try to sign up again so we're going to say test at example.com actually this should be test2 because we already have test and password password and now we'll click sign in all right welcome you successfully signed up that's awesome now we can go over and we were redirected uh successfully so notice that's kind of like how we get over that one error so if you encounter that you can update your navigational formats inside of the initializer for config or the initializer for device we need to continue updating the signup view or the registration view so that it doesn't have two forms on the page so let's go back over there and if we try to go to users sign up now it's going to say you're already signed in right so one thing that we need to do is be like figure out how we're going to do a sign out so one option uh is to use to add a button on every single page that it will submit a like delete request or uh it'll submit a post request in order to sign you out and like reset your login another option is that you can go over to this device config again where the initializer is instead of having sign out via delete we can have this sign out via get okay so now i'm going to restart our server now if you navigate to users sign out you are signed out successfully this is there's a little a couple little downsides to this one is maybe if you have some sort of like screen scraping thing and you accidentally navigate to that page it might sign you out but whatever for now we're going to call this good so we're signed out successfully we want to go back to users signup and we want to remove this entire form from the page and i think we should be pretty good here with our uh with our email address stuff all right so let's go back to the registration new and we're going to remove this form entirely now you'll notice that there is some shared links here now these shared links are going to potentially come in handy and if we look at the view for that partial which is this shared links partial you'll notice that it has like oh you should log in if you're not if you're not on the login page then show a link that shows how to log in if you're not in the sign up page show a link to sign up it also will give you a link to the forgot passwords etc etc so we did not enable uh password recovery so it's not going to show a forgot password but we could theoretically add this new password path whatever for now we're going to call this good and we're going to just manually add this signup or login now when you copy from tailwind ui it includes a comment at the top that says you know in order to use this example you should update your tailwind.config to include these plugins so if we go to our tailwind config you'll notice that we don't have any plugins installed yet so what we can do is just copy this entire plugins section and drop it in here and that will allow us to use this tailwind css forms plugin now if we look at the server right now you'll notice the server crashed that's because it doesn't have this tailwind css forms component yet so we can say npm install that tailwind css forms and now we can say bin dev to restart the server now that it knows how to find the tailwind css forms component all right coming back over here we know that this was completed now also this it says this example requires updating your template so that the html class is h full and the html body is h full now these two tags are set inside of application html erb so if we wanted to we could come in here and say class h full and body is class h full now i'm not going to add the background color because we're going to probably control that in a different way so that's just a choice that we're making at this point all right so now we have a thing that says sign into your account but we are on the registration page so let's actually update this copy a little bit and where it says sign into we're going to say register for a new account now it's also got this logo at the top for the you know um tailwinds ui default stuff that's part of their template so i'm going to remove that and we're looking pretty good so we've got register for a new account or start your 14 day free trial and this is where we actually want to just say like or uh or log in and we're gonna call that good and then this route is just gonna be to user slash sign in and that will allow people to log in let's remove the forgot password link but i'm going to leave remember me and we're going to use remember me on the sign in page and then we'll come back and delete it from the registration page so let's copy this entire thing over to the sessions new this is where the login page exists so now we're going to just paste that in here and now if we go to user sign in now we see a a similar view that we're about to edit so if we save this and refresh the page now we see this uh our new tailwind ui sort of uh template down here we can change the the h2 to say now assign in and instead of login we're going to say sign up come back over here change our path to users sign up and we're going to just delete all of this actually before before we delete the form that was pre-built we need to look at this remember me and see what names it is using inside of the html so that we can pass those down so there's two input boxes here one is a hidden input with a value of zero the other is not hidden and it's a check box with the value of one and the name is uh user remember me actually the name is the same on both checkboxes the values are different one's hidden one's not that's how you can kind of like submit checked or unchecked so if we come back down to our check box here what we can do is copy that paste it and we're gonna set the name um actually we can yeah let's for our hidden input we're gonna say the type is gonna be hidden and the name is going to be something else so the type is going to be hidden for our first one and then the name is going to be whatever we have here so user remember me this is how devise will know that we intend on actually keeping the user logged in now the other thing is that for the hidden input we're setting the value equal to zero and for the non-hidden input we're gonna set the value equal to one that's because when we're when the box is not checked we want to submit false as the value for remember me if the box is checked we want to submit the value 1 for remember me another change we want to do is remove this confirm password we only need that at sign up time not when we're logging back in all right so now we have this sign in or sign up we have our email and password and we have the remember me link and we have sign in okay let's go back to the registrations page the submit button for registration should actually be sign up and now we can remove the remember me link from the page so we can actually remove that entire div so let's go back to users sign up and see how that looks okay this is looking really fresh okay so we don't have a remember me we have email password confirm password and a sign up link that's all looking really good we can click on login this brings us to the sign in page sign in versus login versus register there's a bunch of debate that we can have around that but i think we're at a good point where we can actually just remove all of this content now i did notice this this has um the forgot password link so why don't we add that in on our sign in page so here right after remember me we're gonna add that uh that confirmation or the the um forgot password right back in so let's find forgot password and we will add this link back in here okay so let's add let's re-add forgot password now the forgot password is going to go to a specific path so we'll just look at what that path is slash users password new slash users password new that should give us the forgot password route so now we have this forgot password it brings us to our forgot password link i'm not actually going to style forgot password for now you can kind of like get the idea and go through and update all of the ui so you have all of the pieces sign up and sign in are going to be the two that we're going to see the most so those are the ones that i care the most about making sure they are looking good okay so if we refresh the page now we've got our email input and we have our password input those are looking okay test at example.com enter our password click sign in now when we click sign in nothing happened that's because we have the form um the form is going to the wrong route i think so let's where is this one going inspect so this form is going to users slash sign in and the method is post okay so that's what we want to have happen here so we're gonna have our form go to user slash sign in so test at example.com enter our password click sign in all right now we are signed in successfully so we've got an authentication flow that seems to be working pretty well um this root page doesn't get it's not very nice to look at yet so we're going to come back and in the in the next episode we're going to talk about how we can spruce up this landing page all right so that's how you add device authentication with tailwind ui and making sure that it works in rails 7. thanks so much for watching and we will see you in the next one [Music] --- [Back to all videos](https://www.cjav.dev/videos)
