Let me just make a one final comment here
0:02
on cleanup before we finish with this whole chapter.
0:05
We won't write anymore code.
0:06
Just think about some ideas here.
0:09
Now that we've migrated all of our data over to MongoDB
0:12
if we're truly committed to moving away
0:15
from our relational database and over to Mongo
0:18
or whatever direction you're going.
0:19
It doesn't really matter. The same thinking applies.
0:22
If you're fully committed to being over into that new space
0:25
we've moved our data
0:27
well, the next step would be to go over here
0:30
hit delete, just wipe away all those files.
0:33
Commit that to GitHub.
0:35
Maybe tag it or somehow like create some kind of branch
0:38
or do something to make a really clear spot
0:40
that you can go back and find it.
0:42
But then remove it.
0:44
Don't keep these things hanging around
0:46
because you'll have to somehow maintain them.
0:49
You know, the way it works when you do the scan
0:51
for the routes is it's going to read through all these
0:54
and then these are going to see things
0:55
like the top import SQLAlchemy.
0:57
You'll still have to install those dependencies
1:00
even though you have no intention of using them.
1:01
So wipe that away, delete that file
1:05
'cause same reason that I just described.
1:08
It's going to have the SQLAlchemy dependencies
1:10
and it's going to cause trouble.
1:11
We're not doing that 'cause I want to leave it
1:13
in this state where you can come to this
1:16
look at this migration.
1:17
You can take the data that is being shipped through GitHub
1:22
here and then run this migrate to Mongo
1:25
to actually get the data into MongoDB
1:27
because I'm not shipping the MongoDB database separately.
1:30
It's not so easy.
1:31
So anyway, I think I'm going to keep it for your demo
1:35
for your example to be around.
1:37
However, in practice, once you've made this transformation
1:42
it's time to, you know, put a save point in GitHub
1:46
wave goodby to whatever the other data model was
1:48
and move on.
1:49
If you need it back, there's always source control.
1:51
You can get it back.
