security rule, restrict data connection available in an app according a custom property

[fabricecallegar]

Hello,

I want to restrict data connection available in an application according a custom property.

For example:

list of data connection:

- DC1 => @Customer = A

- DC2 => @Customer = B

- DC3 => @Customer = A

The application is set to @Customer = A

I would like for only data connection DC1 and DC3 to be visible for this app.

How can I do that ?

The security rule works if I write it like that :

resource.@Customer = "A"

=> only the data connection DC1 is available in the application (in all application actually).

However, I don't want the @Customer value written in hard copy in the rule but comes from the same custom property in the application.

something like that (doesn't work):

resource.@Customer = resource.app@Customer

Can anyone help me?

Is there anyone to help me?
