We're starting to put together some really neat building blocks here with our email, Jinja language thing and so on. In order to do our next step,
0:10
we have to build a pdf invoice, and I have a really cool library to show you how to do that.
0:14
And the easiest way for us to do so is to give it HTML as a string and say, Turn that HTML into a pdf.
0:22
Do we have a cool way to generate dynamic HTML just as text? Mm hmm. We sure do build HTML.
0:30
So what about this invoice_HTML= build_HTML('email/invoice.html') and the template will be email/invoice.html and the data will be the same,
0:42
I think should be sufficient. How cool is that? And then we're going to turn this HTML into a pdf with a couple lines of

Python. The first thing we got to do is create this right here, So over here again, we're using our shared layout for all of our emails were

1:29
Really cool. Okay, so can we generate this? Let's go. Look, we've already written all the code to do it.
1:35
Probably let's just print it out and see what we get. Run it and hit it with postman again. All right, let's see what we got.
1:46
It worked. And check this out. Here is our fancy HTML of our invoice. Now, that's just like before,
1:55
But the trick is we're going to turn this into a pdf. That will be really nice in just a second.
