backend development with python

So now we already have everything we need inside this data socios data shouldn't be empty. And then we can test it out with the division gives us the answer. And they are going to see all this code multiple times we're going to get all the images multiple times. And having that said, I think we should just dive straight into this video. It allows you to easily build API's with a lot less code. So it's quite different from normal for loop in Python. So if we say and and now we run it, it doesn't give us anything. So we're passing the string as be gay ID. So you can see, it didn't show anything here. So let's say you have a Django project, or you want to build an API so that others can access your data, or you're just trying it for fun, or just want to build your skills, that Django rest framework is the best way to go. Normally we do have these are this is very good. So we know that the index number of this is one of zero, which is the first one, then we also want to get the face value, which would be zero. Now let's send whatever value is in that URL to this post HTML. We just write the letter, we don't need to add these. defaults should be equals to the date time.no. Now, as a dictionary, again, it sees it as a normal variable. And that is because this link is not seen by Django. And the only thing I want this to average is the room name. Now you see it's automatically prints team, I can do anything in year I can even write a class. And then we just specify where the CSS file is located. But that list is going to be available in our code. Once I run it, you see that it gives me 100, it automatically adds these two numbers or integers together, and then it runs it. You can also have one up your one project or one up and you can just have multiple features. So the base directory shows the root project right here. But now, whatever city is our search, want to get the details, what we're gonna do is go back into VS code. Now we're going to be talking about classes and objects in Python. So now let's head back to the views.py file. Now this is because everything we've been doing sees as being inside this app, this my app. This static file, as I said, is going to contain all the external files we need. That's what comes with the Django rest framework, it actually gives you this nice looking template to showcase your API and basically test all your API's. Now Django knows we're talking about this page, the home page. So does how to basically use the list constructor to specify a list. And then we're also going to do it in the settings.py file. So it should be telling me requirement already satisfied. So I might post this online, maybe when I'm done with recording this tutorial. Now as I printed, you see there is still a top, nothing goes wrong. Now when we save these, come here, but yeah, each refresh and submit again, you can see now we have London. So what this is going to do is we don't need to create a new view in views of UI. So now that we have that we cannot return a response of serializer data. Now this message, what is is just the model that's going to be storing all the messages on this platform or the messages. So this file is really, we need to register our modules, because he says register your modules here. Let's say you're looking for a module that wants you to just do a specific task. So let's run it, you'll see says true because A is greater than B. Now, I hope you understood everything we talked about in static files. fixture, and then we can use this like this. So once you run it, it gives us 78 and 79. You can see right here that we have a little word automatically prints hello world. That is still one that we want to print, I and then we just want to increment i by one So we can see i equals two, i plus one. But for now, we're just gonna stick with just the Django project and the URLs of UI file in it. So what we're saying is immediately a user clicks on the submit button of this post form. But now we're trying to pass an arrow from the user, we're trying to make sure that the user doesn't input anything wrong. In the next video, we're going to talk more about lists, attributes, there are still a lot of things we can do with least in this part, we're going to be talking more on least, specifically, we're going to be talking about lists, functions, or least methods in Python. So coordinates, and then also a strange making sure is a strange. So is dynamic, whatever we pass in the URL. So let me just show you how we do a for loop, or we call the for loop in Python is very easy. So to print a number in Python is pretty easy. So what I need to make sure I'm doing First of all, is that I'm importing that feature, a feature module. But nothing is showing just a blank HTML page, which is this page. And then let's give it a name of register. And then we're gonna do the same thing for the age. So first of all, let's do from rest framework. But when you go to Facebook and you see your newsfeed you will see newsfeed of your own Free is not the another person's friends, or there are countless ways you can think of it. So we don't have access, we can read it is going to tell us false or not that this is true, then I think we are good to go. In this tutorial, we're not going to be building any full project bow we're going to be doing is taking each Django concept step by step using it in a practical use case. So I've seen, once it gets to this j, you It should break, then you should stop that loop. A leaf means require adding another statement is the same thing as if both else if does mean you have if so if a is not true, then you cannot check if A is false. Just gonna copy these, come up into my browser and paste it. Now, we can also, instead of having the break here, I can do something like this. So we're gonna get that room and then create a new room with that particular name. And then this settings file is like the bedrock of your whole project. And then we're just gonna include from the rest framework, dot URLs. But what do you do user is not logged in, so there will be an else there, what I just want to show is this same thing, but what I want to show now is login or signup. So it's gonna give us a notification arrow. So now first of all, let's come here, refresh and get rid of the stress, worry. Good, should we get calls to message so this message, Moodle does object dot future. Front-end Web Development refers to building web interfaces, specifically the parts of the website that the user will interact with. And then we'll say it goes to room objects dot get name equals from. Now let's say want to open a new file and name it new dot p y. Let's take a quick look at the agenda of this video. What Does a Backend Developer Do Actually? Full 2023 Guide - CareerFoundry So as I said, in the introduction to this video, all the source code to everything we're going to be doing on the template file, I'm gonna link it up in the description below. There's an h3 saying the message under less than the full loop. Now we have that website, when a user just comes to code return mi.ml. So right now, right here, what we're just going to simply do is come here, when make sure that you set an action. Now, you know that we said view dot counter where we come into our views, we don't have any function, the name counter, so let's go create that. And then we also want to check let's see if it's a list to say a leaf If the type of value is a list, do print See, value is a list. Now this is the data I get after sending a request to this URL. So now when I run these, you are going to see it prints all these. So request dot get words why we have this word is because it is the name we gave the particular text collator, like the text area, which collected that data, this is the name assigned to it. So we're going to have a new list called URL patterns. Over there, what I just want to do is to see what does look out requests. And after this view, taking a request is also going to take that particular variable which has been passed, which is called PJ. It says invalid data on line one, did you forget to register or load this tag. So from the HTML, we can look through a and get all those attributes we need. That's how you can easily authorize or authenticate in your Django rest framework. This directory is what is in this command line. So that is how to create a simple Django project. So what I just need to do now is to make sure that user should be able to click as you can see, now just plain text is I can't click. So in caso were supposed to have, oh, yeah, I know why the problem is, so right here in our sources function. Like this, then once we print you see tells us for that because we have four keys and values in here. Front-end vs back-end development Types of back-end languages - C++ - C# - Java - JavaScript (Node.js) - PHP - Python - Perl - Scala - Ruby Back-end programming frameworks - .NET (for C#) - Django (for Python) - Spring framework (for Java) - Node.js including MeteorJS and ExpressJS (for JavaScript with Node.js) So now when the HTML, we can look through this list and get the attribute for each of these lists right here, so feature for us all these attributes, Victoria, all these attributes. And the final thing I'm going to show you in for loop is that we can also use the else statement. So now that we know we have a new project started, let's just CD into that project. So you can also you know, use your Python code to convert it very easily. So the reason why it's given us this era, as I explained earlier, is because why isn't a POST method, and then we didn't add the CSRF token. So it allows us to just send user's credentials, and then it obtains the authentication token for us. So let's head back to VS code and continue with the coding. So right now, if I refresh this page, and I hit London, now you see excuse me back in London. Now, this might sound funny, but there is a difference between your Django project and your Django app. Well how can we use these in our views is also very easy to just need to do is to come into our views.py and then right here in the index, where we can just do is to first of all import that model from you. Whenever we are printing a variable, we don't put quotes like we do when we are printing a normal string. In this part, we're going to be talking about writing files in Python. But you can see that those two are shown. Now the reason why these action is blank is because when we eat so search is sending all the data, which is only one actually sending this London data back to this home page. So he's saying what we want to do top who doesn't support it. So once you have all those downloaded and installed, you can just open up your PG admin. So we have the name of coders in this case. Let me look for Swan the as a description. So we need to come into weather detector, which is our main project. I can also give it another lease like xe, Ghana, let me say Nigeria, let me give it one more value. But when I click on it, it still goes through that same age, whatever. So it's intuitive, it will be different for every single person. So I hope you get the concept of class and objects in Python. Now, let's say we want to create an object using this class, we're just going to do is to do something like p one, something like that. And then we can just do exactly the same thing. And once we hit refresh, we should have that styling arrow. It should be under let's say, just give me some password. So we were just having a simple HTML code inside this. So this i is index number is one, if we want to get it, we're just going to say, Len by going to remove Len. But the reason why is because of line 29, where we say return redirect login, let's quickly go back and see what was going on. Like everything we've learnt in this tutorial, I can easily code them yeah, like, let me say, print you enjoying this tutorial. If I over on these, you see dices 18 is i n t, which stands for integer and then seem right here is a string. And that's what the model is a PDF file is for the tests, we we use it in some cases, but not four times, so it's not frequently used. So in this h1, I can have a link tag I say. And that is me, which was the user I created, right here in the command line interface. But now we can make this more, we can step up a little. Now, let's say this data is coming from a database. First of all, let's go back in here, we're gonna cut out of this server. Follow these steps in order - there are plenty of places you can learn back-end online effectively, some of the resources are paid, and some are free. Do we have to do them just quickly bring that back. So instead of feature one dot name, I'll say, feature that name, and feature the details, just the way we do in Python. So now you see says value in the URL is to have. And then we'll say include with the two arrows. So the reason we add the arrow is because right here is always in a backward slash, but we are using in Python, it has to be in a forward slash. And then this ABS Wi Fi, we also use it but not too much.
