Stange problem with dynamic dialogs

[Brackaboy]

Hey everyone,

So i’ve been struggeling the whole day with a very weird issue.

I made a simple script that asks a external CMDB which vlan’s a certain customer has.
The intention of this script is to list all the vLAN’s of a specific customer. So he can choose in which vlan he want to provision his vm.

This is the script (the customer_id is a constant atm to make everything simple):

  require 'httparty'
  $i = 0
  vlan = Array.new
  auth = {:username => $evm.object['user'], :password => $evm.object.decrypt('password')}
  $evm.log(:info, "Device42 Entering getSubnets")
  subnets = Array.new
  response = HTTParty.get("#{$evm.object['url']}subnets/?mask_bits_gt=24&customer_id=3", 
	{
		:headers => {'Content-Type' => 'application/x-www-form-urlencoded'},
		:basic_auth => auth,
		:verify => false,
	})
  response.parsed_response["subnets"].each do |a|
	subnets.push(a["subnet_id"])
  end
  $evm.log(:info, "Device42 subnets are #{subnets}")
  
  subnets.each do |subnet|
  response = HTTParty.get("#{$evm.object['url']}subnets/?mask_bits_gt=24&customer_id=3&subnet_id=#{subnet}",
	{
		:headers => {'Content-Type' => 'application/x-www-form-urlencoded'},
		:basic_auth => auth,
		:verify => false,
	})
	  unless response.parsed_response["subnets"].nil?
		vlan[$i] = response.parsed_response["subnets"][0]["parent_vlan_name"]
        $i = $i + 1
	end
  end
  
  $evm.log(:info, "Device42 vlans are #{vlan}")
  
  dialog_field = $evm.object
  dialog_field["sort_by"]    = "value"
  dialog_field["sort_order"] = "ascending"
  dialog_field["data_type"]  = "string"
  dialog_field["required"] = "true"
  dialog_field["values"] = vlan

This is what i can see in the logs, everything seems normal

And i can also see that the values get inserted into dialog_field[“values”]

Now here comes the weird thing, the service dialog looks like this:

So instead of the names of my vLAN’s it just says “L” for every vlan the customer has.

Does anyone know why this is happening?

Thanks in advance.

This looks like the code is interpreting values the usual rails way - it expects an array of [value, label] for each item.

So, when it sees that KL3_VL4008 it decides that item[0] == 'K' so K is the value, and item[1] == 'L' so L is the label.

So, instead of vlan[$i] = response.parsed_response["subnets"][0]["parent_vlan_name"], you would need something like

label = value = response.parsed_response["subnets"][0]["parent_vlan_name"]
vlan[$i] = [value, label]

@himdel Thanks, I didn’t expected a reply that fast.

I’m going to give your solution a try but after reading your explanation i’ll definitely think it would work

[Brackaboy]

@himdel I just copied your code and it works like a charm, Thanks man

I just found a bug, when i select a vlan to provision the vm it always takes the first one in the list. I think it has something to do with how the values are stored in the array.

This are the logs:

Because when i just code:

unless response.parsed_response["subnets"].nil?
        vlan[$i] = response.parsed_response["subnets"][0]["parent_vlan_name"]
        $i = $i + 1
end
dialog_field["values"] = {vlan[0] => vlan [0], vlan[1] => vlan [1], vlan[2] => vlan [2], vlan[3] => vlan [3]}`

The logs show this:

But not everyone has the same amount of vLAN’s so i can’t do it like that

[Brackaboy]

I finally got the values stored in the array how i want it:

  require 'httparty'
  vlan_name = Array.new
  vlan_name = {}
  auth = {:username => $evm.object['user'], :password => $evm.object.decrypt('password')}
  $evm.log(:info, "Device42 Entering getSubnets")
  subnets = Array.new
  response = HTTParty.get("#{$evm.object['url']}subnets/?mask_bits_gt=24&customer_id=3", 
	{
		:headers => {'Content-Type' => 'application/x-www-form-urlencoded'},
		:basic_auth => auth,
		:verify => false,
	})
  response.parsed_response["subnets"].each do |a|
	subnets.push(a["subnet_id"])
  end
  $evm.log(:info, "Device42 subnets are #{subnets}")
  
  subnets.each do |subnet|
  response = HTTParty.get("#{$evm.object['url']}subnets/?mask_bits_gt=24&customer_id=3&subnet_id=#{subnet}",
	{
		:headers => {'Content-Type' => 'application/x-www-form-urlencoded'},
		:basic_auth => auth,
		:verify => false,
	})
	  unless response.parsed_response["subnets"].nil?
		label = value = response.parsed_response["subnets"][0]["parent_vlan_name"]
        vlan_name[label] = value
	end
  end
  
  $evm.log(:info, "Device42 vlans are #{vlan_name}")
  
  dialog_field = $evm.object
  dialog_field["sort_by"]    = "value"
  dialog_field["sort_order"] = "ascending"
  dialog_field["data_type"]  = "string"
  dialog_field["required"] = "true"
  dialog_field["values"] = vlan_name

It still always takes the first value to provision the vm, it doesn’t matter which one you select.

[enosullivan]

I have issues whereby I have to select a dialogue option twice for it to be actually selected. Not sure if this is related to your issue.

[Brackaboy]

Hey @enosullivan, I think it’s a different issue.

I can select the dialogue option I want first try, but after that it always provisions using the first option from the list. So my selected value doesn’t get passed for some reason.

I also thought about what the issue could be on your problem but i’m sad to say that i really don’t have any idea. If u are using ManageIQ, are u using the newest version of it? Because if u aren’t I would definitely give it a try with a newer version.

Hi

There have been several recent fixes for dialog issues, including:

Fix for drop-down selection on dialogs while ordering service catalog having to select an item twice

Enabled select list to save values on change

I these should fix the problems that you’re seeing.

Cheers,
