Let's get started. So you don't need to understand what I'm saying for now about Django. The 8 Top Back-End Programming Languages for 2023 | Boot.dev - Medium Now this is going to get automatically get an arrow, and then just print whatever we want to tell the user. So since our app is doing production yet, or prigionieri, production is on live on the web or something. So now the oddest is being passed to the URL, it's very easy for us to now get all these values in the backend. Now as you know this value is a string, it is an integer, this is a boolean value. So the first URL, which I specified is the homepage, that's why it's blank. Now not that this can be anything, let me just this in which I put later it can be denoted by anything. Now you see it says it gives us this error. So you can see, it is linked with the age the static files, but not seeing the way Django recognizes it. So it allows us to just send user's credentials, and then it obtains the authentication token for us. So to do lists also mean two dimensional list. And you know, in Django, one ever you create a new module or you add any changes to your Moodle, you need to make migrations and migrate to the database. So this Ajax is not with Python is actually with JavaScript. So for now, this is the main site, and then views dot index. Now, this API key is very important for you to be able to access the API. So what I want to do now is walk you through the steps of how you can connect another database provider into your Django project. So now we're going to be looking at dynamic URLs in Django, to what I mean by dynamic URLs is to for example, we have the same URL but with different ID passed in it. So we can also use the leaf statement or the statement. But I'm sure you can, we are gonna agree with me that what we just did was time wasting. Now this is going to run either there is an error or not. Now, that's apples because of it is actually the same page, like the same HTML file, or the same whatever the same code, but is different for each user. So sometimes when coding with Python, you might want to work with some external files, let's say like a text document, or like, like a spreadsheet, like an Excel spreadsheet, or like an HTML file or any external file. So in Visual Studio, good weather is going to come into the toolbar, and click on new file. A Beginner's Guide to Back-End Development | Upwork So I'm gonna do I'm just gonna close these, and then just keep it like that. And then let me first of all, put this down a little bit. Default, where we see one page bootstrap. And to do that, we're going to come into our command prompt. So it allows various type of data types, we can also do it again for like the Boolean type, I just say B Oh, and the less true or false, and then true again. And then this, I'm going to leave him blank for now. And then once we have the name and age of the user stored, we can just replace it with these as a name. We're just gonna do that to save room details. So what this is going to do is that it's going to look Do it one by one, it goes from j i, then he goes to J au. So if it exists, want to throw an error and say messages. So the POST method is very, very useful whenever you are dealing with some more safe and secure information. So now when I just do something I can just pass for now. And then let's give it a name of user name. I'm going to leave it in the description below. So this is going to flush all the data we have in our database, just click Yes. So anything under this indentation is under this folder, promise I've come out of the indentation of continued coding, the follow up is being broken. So automatically, you see that that we have that message here in the HTML, you see that is North Korea detailed in our code, but that's what that JavaScript code is doing. So now first, to be able to collect this in our views, we need to come here now. Let's take a quick look at the agenda of this video. Now, this concept is very easy to grasp, not only in Python, but in programming in general, there is always if statement, but maybe with different syntax. Now we input the value, let me input six is this six is a string does nice to year. We just write the letter, we don't need to add these. Say it says the amount of words is three, and then our URL is completely clear. Now, then we can run it, I guess see it's print something now. So let's see, most of the time, this happens because of HTTPS. So like these, this function named greetings function is sprinting to the user that welcome. So in this string string gets a lot of function, which does different things. So what this prevent default does is that normally in a form, once we'd submit the page is going to refresh or go to another page. Because to our inputs, I will say and user name. So if anything happened, if we add an arrow, we just say an error occurred. So classes are very broad in Python, and it is very, very used in Python. And then we need to end that if statement. So let me show you what is going to happen right now. And then we can give it something like 10 years. So as you can see, we already have rest framework added on to this rest framework, dots fourth, talking, so that is different. So I can close up my command prompt right now. So first of all, let's say the method it's using to send this data is a POST method. Now index value is just like the ID assigned to each of these values right here. And then right here in index, this is what is going to be rendered when the Index page is called index dot HTML. What Does a Back-End Developer Do? | Coursera A something like that, then we can print we can just bring anything wants to do. How are you guys doing? And then wants you to take your requests. So what is going to be happening is that a user is going to input a sentence. Now, let me explain why all this happens. So right here, it shouldn't be in this old class. So that is duffel, dat, and we'll give it a comma. So now we look through that, and then just get each of the image each of the names and these, I will save it. I want to first make sure that I have Django installed. Now this part is going to allow us to us multiple URLs in our list. And if I do, I'm going to leave a link to the description, the description. Without these libraries, you're going to receive an error. Now that is saved coming, I need to refresh. So why does give me Python a condition before it runs the code? So when I run this, you see is a boy or a short, both, if I change this now to and you see that it doesn't print this, it will print a is none of the two. What is it getting for only this type of error? Kotlin 9. So it tells me where Mongo is located in this list, which is very, very helpful. We have a variable named number equals to 55. First of all, let's cancel this and make sure we know where this is saved. And then we don't know the amounts that is being passed. But that also has his installation process. That is showing that the CSS is working on this HTML file. Now what I just need to do is to install it, I'm just gonna come into where I saved it. So and if they will come in each refresh again. So that is how to use return statements in a Python function. Now when we come here at refresh, you're gonna see that this code, this block is going to appear four times to see fast, reliable, easy to use and affordable. So now, once exactly gone, it should take it to a dynamic and unique page. So right here, this is where we need to do some work. So this shows that it is coming from our index dot HTML file, not from an HTTP response. And then we have one more call our plus, this means we want to do both reading and writing. Back-end Development refers to the . So now, we can just say want to get only the first letter. You see right here, we added codes, and inside our code we put team, but for it to be an integer, you will see that we do not add codes. Else that means if any of these is false, we just want to do is to create the user. And let's say it would be something like user dot name, I show this and something like user name. So as you can see, remember that the different details of the particular room from the model. Now Django has this command line, which allows you to create a project a new project. What is web development? So after having that done, I would just add an arrow. So we want you to be real time, want everything to happen. So now that we know that room ID, we cannot get all the messages. So if I say admin, and I come here and just input the password, and I enter, she's gonna take me to an admin dashboard, as you can see right here, right here, I can maintain and control my size, any hour, like, without even having an external database UI. So we use Annie's data to get whether that particular feature is true. Now, when I say use authentication, what I mean is signing in as signing up to a platform, like when you go to facebook.com, and then you sign in to the platform you're dedicating to your account into that platform. So as you run you see is this A equals B, where we change is now to three. So right here in this form, we need to create some things which are going to allow us to submit that obviously, so in the form, we're going to listen, the form, right should be down below, discloses. But before we do that, if we just type return, render this out to render an HTML page, and we do requests index dot HTML, if we do this, we aren't going to see this is either going to give us an error or is going to show us the Django default template. We can also install markdown on the Django filter, but we don't need that for now. So I'm going to leave that blank for now. And we're going to talk more about get on POST method when you're dealing in Django. And then first, to get it to see requests that get getting worse, I'm going to explain all this. So this error is because we don't have any URL named login for now. So as you can see, it says how to deploy a Django project to Roku.

If this is false, that's simply because this upper case and lower case, not everything is upper or lower. Now to create an app does when we use this manage dot p y, in earlier I explained that this money does pure y, we don't really want to code anything inside it, but we use the file a lot for different things. dots room, I'm gonna give it a name overall. And I run it you see it changes and it says hello world welcome. So I'm just gonna drag and drop into VS code. So that means in this views.py file, it should look for an index function and then do whatever was being asked to do. So right here, I'm trying to concatenate with a variable named name.

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. And then let's move straight into Django rest framework serializers. So now that we have that we cannot return a response of serializer data. But when we come here on each refresh, we're gonna see one more minute.
