View functions

View functions

A view function, or “view” for short, is simply a Python function that takes a web request and returns a web response. This response can be the HTML contents of a Web page, or a redirect, or a 404 error, or an XML document, or an image, etc.

 Example: You use view to create web pages, note that you need to associate a view to a URL to see it as a web page.


1.-We created a return function in HTML called hello world

In Django, the index is the main page of an app.The only HTML we request right now is the "Hello World"

URL Mapping

So basically we are mapping #index to products page ( in other words, we are making it the main page)



2.-We will close the view folder Let's create a new python file

Now we are mapping first to the root ( /products  '')   and 2nd to the views module

3.-Now let's collapse the product folder and open the pypyshop folder...from there go to the root in urls.py


Now we will tell django about the url mapping and the view page ( django doesn't know yet)


Finally, we will let them know about the product page

we will expand "import"..and we will add the word  " , include"

In the produce tab we can see this

we are telling Django that everything with /products , send them to produce tab page

Now testing the app with the name /products

But when you come back you will see this:

Exercise:
 Make a new page called new products

Then we go back to URL to map  the new Products  function

Now let's go to Products folder, and them to URL to map it

Now we will check this in our browser
