From YouTube: Demo of creating sub group in shard with Rails 6 1

Description

Part 2 from https://www.youtube.com/watch?v=VBm6mSJmRhw

A

B

A

Two of the horizontal shorting with this 6.1 uh investigation.

B

A

Have here an mr that I created that, where.

C

Some things work so, namely we have these uh namespace, abstract class and I've converted a few models to to use this abstract class so that we can connect to.

D

Multiple databases, namely namespace and then remember, because groups have members and also.

E

So and what that achieves is that.

B

If we have a group, that's already created in chart conveniently.

F

uh Calculations create a lost and fun move. We can.

G

Show the group, so this lost and found shot only exists, so this loss and fun will only exist on the.

H

G

H

It doesn't exist in default.

B

So we can load the page, but um this one does an additional.

F

Request I mean that probably runs in the context of the main database. So that's probably wrong and we can also.

I

Create a show, the form for a new subgroup, and we create a new subgroup say.

B

And this this will this.

J

Will create a new subject inside the shower and.

K

H

L

um Unfortunately, if we refresh the page and show box.

M

So, let's, let's briefly talk about how I invented this.

E

So a lot of it, we can.

N

Sort of push it down to this abstract class and have different uh helpful methods.

O

To connect the right row and sharp, and then we can just do whatever we want.

M

Inside the block- and I think a lot of that we can accomplish through um around actions.

E

So we can say shard and then, given the group, the group should tell us what chart it is and we.

P

Will have to implement kind of look up tables for all the different ways. The idea of a group, for example, or the partial group or the.

H

Q

Yeah, oh yeah, so um one last thing is: um I had to kind of configure this to false legacy. Connection handling uh my sensor. I think it's safe to do that because unless.

F

We actually directly use the internal connection handler.

K

Rails api: we should be sent to this default yeah. That's that's it. Thank you.
