What We're Going To Do
3:27We should nail down what we want our app to do. Let's stub out most of it with comments.
[MUSIC]
0:00
What I wanna make is a simple command line
application that will let me record
0:04
thoughts or notes, stick a time stamp on
them, and save them to a database.
0:08
I should also be able to page through all
of them in some sort of order.
0:12
I'll want to delete the ones I don't need
anymore.
0:15
And I'd love to able to search for phrases
in all of the posts.
0:17
I bet we can do all this in about 100
lines of code.
0:21
What do you think?
0:22
So, I've gone ahead, and made a file
called diary.py.
0:24
You can call this journal.py or whatever,
if you don't like the word, diary.
0:27
And again, of course, we need to import
everything from peewee.
0:33
So, from peewee, import *.
0:36
And, just like last time, we need a
database, and a model.
0:40
So my database, I'm gonna do again, Sqlite
database, and I'm gonna say diary.db.
0:44
And then I'm gonna create my model, which
I'm gonna call entry.
0:53
And again, it extends from Model.
0:58
So, what I wanna have in here is I wanna
have content.
1:00
I wanna have a timestamp.
1:04
The Meta is gonna be database equals db.
1:08
Yeah?
All right.
1:11
We're gonna have a menu.
1:16
So, I need to be able to show that menu.
1:18
This should be something that runs
continuously like all
1:20
the menus that we've done in the past.
1:24
So, you know, probably want to have a
while loop.
1:26
But I, I wanna make sure and
1:29
have this in a function cuz I don't want
the script to just run all the time.
1:30
I, just, it's a little bit nicer
organization.
1:35
So, let's call this menu loop.
1:38
And we'll say, Show the menu.
1:41
All right.
1:44
So, we know we're gonna have some crud.
1:46
We're gonna do creating, and reading, and
probably wanna do updating.
1:50
But we'll do creating, reading, and
deleting.
1:53
So, we should make functions for that.
1:55
So let's do an add entry.
1:57
And we're gonna say Add an entry.
2:02
Always important to have your docstrings
kids.
2:07
Just remember to keep those in there.
2:12
And then for the reading part let's say
view entries.
2:14
We're gonna look at all the entries, and
we'll say View previous entries.
2:18
And then we're gonna have a way to delete,
so, let's say delete entry.
2:25
And I think that's probably gonna get an
entry passed to it.
2:31
And we'll say Delete an entry.
2:35
All right.
2:39
And then like I said, I wanna, I wanna be
able to run this file so that it runs, but
2:40
if I ever wanna import these into
something else, like maybe I wanna turn
2:45
this diary that works great on the command
line into something I can use from Flask.
2:49
I'd wanna import this, I don't want stuff
to just run when I import it.
2:55
So, we're going to add another one of
those if name blocks.
2:59
So, if name is equal to main.
3:04
And then we're gonna have the menu, so,
we're going to run menu loop.
3:07
So, okay.
3:12
I think that's what we need to have in
order to get everything.
3:14
We'll flush this out as we go along.
3:18
Maybe my hundred line estimate isn't so
great, but it's just comments so far.
3:21
Okay, let's get connected to the database
and write our model.
3:25
