Today i have written another [Patch](https://github.com/saltstack/salt/pull/34566) for [salt.pillar.mongo](https://docs.saltstack.com/en/latest/ref/pillar/all/salt.pillar.mongo.html),
this patch allows us to include pillar entries from previous files/includes in the current one.
This is usefull when you want to calculate for example network data with/or without defaults.

### Code
This is my **defaults** file which i have stored in **pillar/pcdummy/roles/base/common_pcdummy**:
```yaml
include
:l - users.pcdummy
- roles.base.common
- roles.base.mongodb_client
_data:
domain: pcdummy.lan
aptcacher:
address: "http://aptcacher.pcdummy.lan:3142"
mail:
relayserver: "mx0.lxch.lan"
rootalias: "rene@jochums.at"
check_mk:
ipv6: True
only_from: '::1 fd57:1:see:bad:c0de::14'
network:
managed: False
pubinterface: eth0 # Take hosts entries from this interface.
intinterface: eth0
interfaces:
eth0:
enabled: True
configure: True
type: eth
noifupdown: True
ipv4netmask: 255.255.255.0
ipv4gateway: 10.167.160.1
ipv6netmask: 64
ipv6gateway: 'fe80::1'
resolver:
nameservers:
- fd57:1:see:bad:c0de::18
search:
- pcdummy.lan
```
This is the **host definition** for the host `srv01.pcdummy.lan` which is stored in the mongodb and
which will be retrieved over ext_pillar mongo.
```json
{
"_id" : "srv01.pcdummy.lan",
"include" : [
{
"file" : "roles.base.common_pcdummy",
"saltenv" : "pcdummy"
},
{
"file" : "global.generator",
"saltenv" : "pcdummy"
},
{
"file" : "roles.base.server",
"saltenv" : "pcdummy"
},
{
"file" : "roles.base.postfix-relayclient",
"saltenv" : "pcdummy"
}
],
"_data" : {
"network" : {
"managed" : true,
"pubinterface" : "lanbr0",
"intinterface" : "lanbr0",
"interfaces" : {
"eth0" : {
"configure" : false,
"bridge" : "lanbr0"
},
"lanbr0" : {
"enabled" : true,
"configure" : true,
"type" : "bridge",
"ipv4address" : "10.167.160.14",
"ipv4netmask" : "255.255.255.0",
"ipv4gateway" : "10.167.160.1",
"ipv6address" : "fd57:1:see:bad:c0de::14",
"pubipv6address" : "2001:1:see:bad:c0de::14",
"ipv6addresses" : [
"2001:1:see:bad:c0de::14/64"
],
"ipv6netmask" : "64",
"ipv6gateway" : "fe80::1",
"ports" : "eth0",
"stp" : "off",
"delay" : "0",
"maxwait" : 0,
"fd" : 0
}
}
}
}
}
```
And this is the generator stored in **pillar/pcdummy/global/generator.sls** which generates
pillar data from the above merged data.
```yaml
#!jinja|yaml

{% set data = pillar.get('_data', {'network': {'managed': False}}) %}
