Conclusion

In Function-based views, pass the value of context to template to complete the HTML. A type of rendering.

What is rendering in the first place?

It refers to the generation of images, videos, sounds, etc. using computer programs from abstract, high-order information described in a data description language or data structure. (Source: Wikipedia)

What is render in Django?

To generate HTML from the information defined in View (or obtained from model) using render (by passing context (information) to template).

Django has rendering methods other than render, but this time I made it the most solid and easy to learn.

render method

The render method takes three main arguments: request, template_name and context.

`view.py`


def test(request):
    context = {{ 'info' :'Pass this' }}
    render(request, template_name = test.html, context)

request It consists of session information, call method (GET, POST) information, etc. If this function is called from the outside (HttpRequest), the call information is included. The place to specify the function in the View to call is urls.py.

template_name Specify the destination (html file) to pass the context (info this time) from the template folder.

context Specify the information you want to pass. If it's a dictionary, it doesn't matter if it's not named context.
