run jobs in the background with rails this is a good video for you to jump in on uh in the last episode we showed how to upload a video to the youtube api and we've been talking about interacting with the youtube api we're building a tool for automating syncing descriptions and titles to youtube but as part of that we need to run some background jobs one of which is going to refresh our our authentication token with youtube and so today i wanted to just go down the path of trying to implement some background jobs with rails and talk about how i like to set that up i active job is something that's built into rails it's part of part of the way that part of this tool set that you get with rails and it has a nice clean interface where you can you can generate jobs and you can just implement the logic that you want to to execute in the background in this perform method you can set up different cues so that they execute with different priorities and such and then there's a whole suite of different adapters that you can use so do you want to use sidekick or rescue or there's several others so here's like sneakers and sucker punch and delay job and q classic and q so these are just a bunch of different types of cues the one that i've had the most success with so far is using rescue so i've tried a bunch of these different ones i use delay job for a long time but the one i prefer now is rescue so we'll go through the process of setting up background jobs using rescue with our ruby on rails app so the first thing that we want to do is uh before we get too far i'm just going to say like rails g job and our job is going to be called youtube or like refresh youtube token and that's going to generate a a class for us that will inherit from active job and is going to allow us to execute either immediately or asynchronously in the background and rails is going to handle most of this for us we just kind of need to do some configuration to get rescue set up so part of part of the way that we test this locally i'm not sure why this is hanging so long but part of the way that we test this locally is with redis server and that fires up a redis server so redis is a type of database this is going to be like an in-memory database that generally is a key value store so it's sort of uh in this flavor of nosql and let's see so our i don't know why our job thing is taking so long to fire up there but while while that's waiting you can once you have the redis server you can also use the redis uh cli to like log into that and it's yeah it's just a key value store so you can say like set foo and bar is maybe the value and then you can say like get bar or sorry get foo and that will give you back bar right so like you're kind of just setting keys and values and redis is really helpful for things like caching but also yeah it's it's commonly used as a backing store for the like serialized arguments that you're passing into a queue that will be then deserialized and read by the job system so that they can be executed alright so we've got our job created now we can open this up and take a look so you'll notice that it's queued as default for now we'll just say like puts let's refresh the token and this is just going to kind of be like our hello world and we want to see this log to the console when we execute things so we've got our reda server running we've got our job created the next step is to install the redis gem so we're going to go to the gem file and go to the very bottom here and say gem rescue sorry not not the redis gem the rescue gem so now we can say bundle install and this will install rescue okay the next thing we need to do is configure application.rb so that when it fires up it starts this or it uses this adapter as the queue so we do config.activejob.q adapter is is rescue next we need to go to our rake file which is just in the root of the project here and we need to require the rescue tasks require rescue tasks and we need to add the task for rescue setup and give that the environment now we should that should be the bare minimum that we need so once we've installed all this and from the rails console we can use that new job that we just created so um refresh youtube tokenjob.perform now so if we say perform now then we see let's refresh the token is just executed immediately so perform now is a method that you get out of the box and this is how you execute something synchronously and then perform underscore later is how you can execute something later so this has enqueued a new refresh token job so that in queues the job but it doesn't actually start like executing the workers all right so let's let's run uh q is all of the cues and then rake rescue work and this should run all of the enqueued tasks so now we see let's refresh the token so if we were to enqueue another one here and say perform later now the task is enqueued and over here we should see another let's refresh the token pop up and we do so that's happening in the background this is actually being performed later notice that we're not seeing any output in the terminal for rails console that's because when this returns that's just returning it's returning synchronously with the result which is an instance of that job uh that fired but it's not actually outputting let's refresh the token because that's happening later in the background and is being you know printed in uh in the log here where we're actually executing those tasks with uh rake rescue work okay so this is this is really kind of like the bare minimum to get the background jobs running but there's a couple other really helpful things we can do so in routes.rb a really common thing to do is to say mount rescue server.new and we can give it uh at a specific like slash jobs or something this will will mount a a special uh rails engine at slash jobs that'll allow us to like view the jobs that are enqueued so now if we split this again and start a server and then go to localhost 3000 jobs so i forgot one thing and that was to require rescue server in here be able to restart the server now from the browser 3000 localhost 3000 jobs brings us to this page where we can see like the failed jobs we can see which jobs are working um this was actually failed jobs from another from another project uh because we're just using the same redis database so we can say clear the failed jobs and so now we have no failed jobs right and we have only one queue that's the default queue so if we were to try to execute this again in here if we refresh we see one job is in the default queue and it's already it's already sort of executing like really quickly so one thing we could do to just see what this looks like is if we go into our job and rather than just printing something we could like raise some exception inside of there and now if we were to say perform this later right now we see that the job has failed so if we go to the field jobs we can see that it failed and it raised hell and if we were to go back and say okay like let's fix our bug and remove the raise hell now we can refresh this page and we can actually retry this exact job so here in the terminal right we have four let's refresh the tokens if we say retry the failed job then this is gonna try try the job again and we should see now five so now we see five refresh let's refresh the tokens being printed to the console so this is kind of helpful if you want like a web interface for for um like managing your jobs one of the downsides is that right like at this point anybody like even external users could just drop in and view this page so it's important that you protect this and that only authenticated users are allowed to access this and so one thing you can do is from your routes file you can wrap this engine mount statement in authenticate user and now if you try to go to like if you are logged out and you try to go to slash jobs then you should not be able to see slash jobs right but if you log in as any user and then go to slash jobs you can see like now any user who's logged in is able to see this so any old user could just go they could sign out they could sign up as some new email address and then password password and they can sign up and now they could just go directly to slash jobs so this is also like it's just one layer of difficulty further but we can do one better and that is this authenticate method that is available from devise this is because we have devise for users this is saying only mount and allow access to this route if you are an authenticated user but we can also pass this a lambda expression that takes in the user object and we can say like only and then we can evaluate to true or false so we want to say like u.id is one or something so like this will only work for the first user so now if we refresh we're not able to see it but if we log in as the first user that's also really hard to see so now if we log back in as the first user and go to slash jobs we should see it so like only if only the user with id one is able to see it now so like you could theoretically do something like if user.admin question mark or something like that if you wanted to have a flag on the user that allowed them to to access this sort of backend content i'm going to keep it really simple and just say like if it's me i'm going to be like user with one right so if it's me then i'm able to see slash jobs and that's it so that's that's how you can like restrict access to the the web view for jobs all right so now we have we technically have a working system for running background tasks uh i think i'm gonna wrap the video there and in the next one i'll show how to deploy this to heroku we're just gonna use like one of the heroku add-ons for redis and uh yeah show how to set this set this all up in heroku so we'll see in the next one [Music] --- [Back to all videos](https://www.cjav.dev/videos)
