Is it possible to have a condition for a custom variable? - tfs

Suppose I want to create 3 custom release variables on TFS.
variable1
variable2
variable3
can i specify somewhere that to enter a variable3, user must enter variable1 and 2?
i cant prepopulate them myself because the input is quiet dynamic.
for now i am using an ugly method like this:
variable2_MUST_ENTER_VARIABLE1_FIRST
variable3_MUST_ENTER_VARIABLE1_AND_VARIABLE2_FIRST
i wish there is a way to specify some sort of note next to the textbox or something :/

Is it possible to have a condition for a custom variable?
The short answer is yes. But I could not quite confirm if it is what you want.
To set a condition for a custom variable, we could enable a custom condition on the task in the pipeline:
Conditions:
Conditions are written as expressions. The agent evaluates the
expression beginning with the innermost function and works its way
out. The final result is a boolean value that determines if the task,
job, or stage should run or not. See the expressions topic for a full
guide to the syntax.
example:
and(succeeded(), ne(variables['variable1'], ''))
But, this condition for a custom variable will be applied at build/release time instead of entering the value of variable.

or something
If you want to set the condition for a custom variable on the UI, I am afraid there is no such better way than you are using at this moment. You can add your request for this feature on our UserVoice site (https://developercommunity.visualstudio.com/content/idea/post.html?space=21 ), which is our main forum for product suggestions.

Power Automate - How to create Azure DevOps work items only once when the trigger is a work item update?

Context
I want to create a Power-Automate flow that automatically creates a sub-task in Azure DevOps when the Effort of a PBI is set.
When the Effort field goes from blank to a positive value, the task should be added (using the newly set Effort value as the task's Original Estimate and Remaining Work).
I managed to create a flow that does that using When a work item is update trigger.
Problem
The flow runs too often (whenever the work item changes, as long as the Effort is > 0).
Question
What would be the best way to ensure this flow runs only once per PBI?
Thoughts
Perhaps check for the presence of child tasks?
Perhaps set a hidden property when adding the task the first time and check that property afterwards?
You could add a trigger condition to the settings of your trigger action. Use the following expression:
#greater(triggerOutputs()?['body/fields/Microsoft_VSTS_Scheduling_Effort'], 0)
Add a Send an HTTP request action directly after the trigger. Use the following URI:
YourProjectName/_apis/wit/workItems/#{triggerOutputs()?['body/id']}/updates?api-version=6.0
Add a Filter Array. Use this expression for the From
body('Send_an_HTTP_request_to_Azure_DevOps')['value']
In the where of the Filter Array use the following expression which you add via the advanced mode:
#greater(length(string(item()?['fields']?['Microsoft.VSTS.Scheduling.Effort']?['newValue'])), 0)
In a condition check if the Filter Array returns no results. If it does, the value of Effort has not been changed in the past and you can safely create your new task
length(body('Filter_array'))
is equal to 1

Integromat Scenario: One-shot module after iterating through a loop

I have created a scenario where I iterate through multiple modules with an array of data. This works fine.
After this completes, I want to run a module once before the scenario completes.
How do I add a module that won't get called in the loop?
There are few ways to achieve this,
Use Router to Create a new Route that will be triggered after the
first route is complete
Trigger new Scenario via Webhooks after you are done with the
scenario
If you are working with array, then using Array Aggregator or other
Aggregators will allow you to first complete the iteration and then
trigger the module you want to use
I am not sure exactly what you want to do after the iteration is complete, but setting the scenarios as displayed in the screenshot below should help you get started on this,
Using Router
For this you can create a router, the upper hand of the router is always executed first, so the iterator and other operations will be done there. After which, the next hand/route will be executed which will be the module you want to trigger at last.
However, If you want to pass some values from the first hand/route to the last one then you will need to set a variable and fetch it on the second route. See details here : https://www.integromat.com/en/help/converger
Using Aggregator Module
You can either use Array, Text or Numeric Aggregator to aggregate all the iteration operations and then trigger the module that you want to use at last.
As far as my knowledge goes, there is no Integromat default modules that can be configured before the scenario ends. We can leverage the Integromat API in future that is currently in development to do so.
I found a filter to be the most easy way of doing this. Essentially chekcing if this bundle position is equal to the total number of bundles!
If you're interested in doing something on the last iteration only, you can use a filter to check if the current bundle is equal to the total number of bundles
last bundle filter

Freeradius accounting filter

How to configure accounting filter?
For example, there are two types of users:
jack#gmail.com
anna#yahoo.com
123qwer-user
It is necessary that only the user jack#google.com and anna#yahoo.com. I have tried to write regex to the accounting section, but it didn’t work.
You can use string filter with "=~" in if condition of the authorize section. Note that you can only apply this to only string so use attribute value in string like %{User-Name}
you can use simple regular expression like "[\w-]+#([\w-]+.)+[\w-]+" for comparison
I do not have an instance running currently to try, Will spin one soon and try and update the actual condition.
Hope this helps.

How to set root construct for SnakeYaml?

I'd like to a construct which is going to kick in by default and therefore I'll be able to extract some metadata and remove it from the parsed YAML.
For instance I could have a construct to do that but in SnakeYAML to register a construct one has to specify a String for it meaning that it has to have a name. However, I don't want that but instead I want my tag to be a root one, a default one which always will kick in so to say.
Is there a possibility to do something like that?
Cheers,
I actually found the answer myself, there is a property
at org.yaml.snakeyaml.constructor.BaseConstructor#rootTag which one can set a tag like:
super.rootTag = new Tag("!root");
The rest is simple because one has to only register that construct to org.yaml.snakeyaml.constructor.BaseConstructor#yamlConstructors and you are done. Your construct will be triggered in all read attempts.
Hope that helps to someone,
Cheers,

How to access a scope if its name is being used as a query column

Dealing with some legacy code we came across a rather annoying situation. We are looping through a query with the <cfoutput query="x"> tag. That query has a column named 'url'. Within that loop we need to check if a key exists within the url scope. Since CF puts a priority on what's in the query over general page scopes I can't use a structKeyExists(url,"key") since as far as CF is concerned at this point, url is a string with the value from the current row of the query.
How can I break out of the query scope and inspect what's in my url?
As a temporary we are using isDefined("url.key"), but I would still like to know if there is a way to break out of the query scope.
Also can't really change the column, or even the column name in the query without a few hours of work tracking down an changing all references to it, so we're going to avoid that if at all possible.
EDIT:
There seems to be some confusion as to how this code is set up, and why the simple solutions don't apply. It would be hard for me to give a thorough example but I will try to clarify the situation.
There are many pages that would count as 'pageA' for the following example. Enough that changing how things work would require a change in scope and investment in time that's just not going to happen in the time allotted.
PageA runs a query with one of the columns being named url, then starts an output loop via cfoutput, inside that loop PageB is included. One PageA may have different variables in the URL scope than another PageA, actually they are the same, but may be named differently(varID=x in one case vid=x in another). Inside of PageB I need to use the value from that url scope, so I want to run through the different possible names (if key 'varID' exists in url, use it, otherwise use 'vid').
This is why I want to "punch through" the query scope to get the url structure, and not the url column from the query. Any other method seems to require modifying the many PageAs.
So the question is not how to solve this problem specifically, as there are many ways to do it, I would just really like to avoid them as they all add a lot of time in implementation and testing. The question remains, is there a way to access the url scope as a variable if url exists as a query column and you are in the query scope.
I thought it might work to create a function that returned the url scope, but upon testing it, even with a local-scoped query (which prevents the function using the query itself) the use of url inside the function is still corrupted:
<cffunction name="getUrlScope"><cfreturn Url /></cffunction>
...
<cfoutput query="x">
<cfif StructKeyExists( getUrlScope() , 'key' )>
<!--- still fails :( --->
There is however an undocumented (meaning unsupported and liable to change) option. If you dump getPageContext() you will see a bunch of functions that do interesting things, including dealing with scopes.
You can use getPageContext().SymTab_findBuiltinScope('URL') to get at the URL scope.
You can also use getPageContext().getCfScopes() to get an array of scopes. I'm not sure if the order is guaranteed fixed but it seems to be [cgi,?,url,form,cookie,?] checking on both CF10 and cflive (CF9), so possibly is.
(In CF8 there was the method getBuiltinScopes, which returned a struct instead of an array - this no longer appears to exist, reinforcing the whole unsupported and changeable nature of these methods.)
On Railo those don't work, but there is getPageContext.UrlScope() and similarly-named functions for the other scopes.
One solution would be to assign the url struct to a new variable outside of the cfoutput tag and then reference that variable instead of url. Example:
<cfset urlScope = url>
<cfoutput query="x">
<cfset keyExists = structKeyExists(urlScope, "key")>
</cfoutput>
My solution for this is always to alias the url column in the query as int
SELECT URL as qURL FROM myTable ...
IF you don't have access to the query (it's a stored precedure or used elswhere etc) you can always use query of a query to reselect it with your alias.
I don't care for the idea of creating a separate reference to URL outside the output - but that would also work. I just want to KNOW what is user input (i.e. comes from the URL or FORM) and what is generated internally (i.e. comes from a query).
Couldn't you move structKeyExists(url,"key") outside of the cfoutput block, and store that into a variable? Or do a structAppend to copy the url struct into another struct named something else?
Another approach is to replace your cfoutput block with a cfloop block.
<cfloop from="1' to = "#YourQuery.recordcount#" index = "idx">
<cfif StructKeyExits(url,"key")>
<cfoutput>
#url.key# is not the same as #YourQuery.url[idx]#
which can also be referenced like this #YourQuery["url"][idx]
etc
