Filters for device page fields

1

Hello,

We were trying to filter device page fields but not having much luck. We tried doing something like this:

- label: '"WiFi Network Name"'
  parameter: VirtualParameters.WiFi-SSID
  filter: VirtualParameters.Hardware-Type = "MRR"

It doesn’t error out, but it still shows this field for devices where hardware-type is not MRR. Am I putting the filter parameter in the wrong place?

The filter property only works with the container component.

Thanks - Then how can parameters in the parameter-list be filtered? I have some parameters in the parameter-list that only apply to certain types of devices - I am unsure as to how to make those parameters only appear for those devices. Can I put a parameter-list inside a container somehow (or vice versa)?

Try this:

- label: '"WiFi Network Name"'
  parameter: VirtualParameters.WiFi-SSID
  filter: VirtualParameters.Hardware-Type = "MRR"
  type: "'container'"
  components:
    - type: "'parameter'"

This replaces the default component (i.e. parameter) that is used to render each individual value. It replaces it with a container component with which you can use the filter property. The parameter-list component will then skip any item that renders nothing.

I should’ve mentioned this solution in my previous answer but oddly enough it didn’t occur to me until you asked a direct how question :slight_smile:

Thanks!

Any similar way that an entire parameter-table could be hidden? For instance, there is the hosts table that doesn’t really apply to devices that aren’t routers - so if the device is not a router, there is a useless “hosts” table that will always be empty taking up vertical space on the device page.

You could put that parameters-table component inside a container component.

Thanks, I’ll give that a try - I think I’m starting to get the hang of nesting components.

So when I try changing this:

- label: '"Wireless Radios"'
  parameter: Device.WiFi.Radio
  type: "'parameter-table'"
  childParameters:
    - label: "'Status'"
      parameter: Status
    - label: "'Frequency'"
      parameter: SupportedFrequencyBands
    - label: "'802.11'"
      parameter: SupportedStandards
    - label: "'CCQ'"
      parameter: X_MIKROTIK_Stats.OverallTxCCQ

to this:

- filter: VirtualParameters.Hardware-Type = "MRR"
  label: '"Wireless Radios"'
  parameter: Device.WiFi.Radio
  type: "'container'"
  components: 
    - type: "'parameter-table'"
      childParameters:
        - label: "'Status'"
          parameter: Status
        - label: "'Frequency'"
          parameter: SupportedFrequencyBands
        - label: "'802.11'"
          parameter: SupportedStandards
        - label: "'CCQ'"
          parameter: X_MIKROTIK_Stats.OverallTxCCQ

The device page refuses to load after that - any idea as to what I am doing wrong?

Move the parameter property down to the parameter-table component.

That works, thanks! Why is that different from Filters for device page fields - #4 by zaidka where the parameter property is at the top level? I wasn’t entirely sure why the parameter property was at the top level there and why it is in the parameter-level component in this case.

i.e. why is the solution in post 4 not this:

- filter: VirtualParameters.Hardware-Type = "MRR"
  type: "'container'"
  components:
    - type: "'parameter'"
      parameter: VirtualParameters.WiFi-SSID
      label: '"WiFi Network Name"'

Just curious

In the case of parameter-list, the child components are “contextified” so the parameter arg automatically propagates to the subcomponents. The container component doesn’t do that because it’s just a wrapper and doesn’t add any context to its subcomponents. Hope that makes some kind of sense…

12

Yes, that does make sense, thanks! I figured with your original response that there was some kind of inheritance involved regarding propagation of settings to the lower levels. So in that case, I assume it might also work as shown in my last post? Or is the solution in post 4 the only one that would work for that?

13

Correct. The solution in your last post should work too.

can you give some example regarding using filter on parameter table. where i should move the parameter type?
