I have a Microsoft Form (customer facing), that has several fields with values such as UK/Europe. Ultimately within Power Automate, I need the value as "uksouth" for example. I know I could initialize a variable and use if statements to swap them, but that is cumbersome and would make expanding the list later on more difficult.
Not a programmer/developer, and just starting to explore JSON, variable manipulation, etc.

I just came across a JSON wannabe that decides to "improve" it by adding datatypes... of course, the syntax makes it nearly impossible to google.
a:4:{
s:3:"cmd";
s:4:"save";
s:5:"token";
s:22:"5a7be6ad267d1599347886";
}
Full data is... much larger...
The first letter seems to be a for array, s for string, then the quantity of data (# of array items or length of string), then the actual piece of data.
With this type of syntax, I currently can't Google meaningful results. Does anyone recognize what god-forsaken language or framework this is from?
Note: some genius decided to stuff this data as a single field inside a database, and it included critical fields that I need to perform aggregate functions on. The rest I can handle if I can get a way to parse this data without resorting to ugly serial processing.
If this can be parsed using MSSQL 2008 that results in a view, I'll throw in a bounty...
I would parse it with a UDF written in .NET - https://learn.microsoft.com/en-us/sql/relational-databases/clr-integration-database-objects-user-defined-functions/clr-user-defined-functions
You can either write a custom aggregate function to parse and calculate these nutty fields, or a scalar value function that returns the field as JSON.
I'd probably opt for the latter in the name of separation of concerns.
I have a complex many-to-many relationship defined. The cross-reference table is an entity, so I have Contact with a One-To-Many to ContactList, and List with a One-To-Many to Contact List. Contact List contains listID, contactID, and a few Booleans. The relationships seem to work well and on the backend I can get a list of contacts on a review list using the Spring-Data-Jpa findByContactListsIn(Set).
However, I am trying to build a list of contacts in Freemarker, and show whether they were in the current list.
Before I made an Entity out of ContactList, I had a standard Many-To-Many relationship between them, and I was able to do something like this in my .ftl:
<#if list.contacts?seq_contains(contact)>
But I needed to add some data to ContactList specifically, so I needed it to be more complicated. How can I do something similar now? I tried:
<#if list.contactLists?seq_contains(contact)
But of course that always returns false, because it is comparing two different entity types. Is there a way to find if a contact is in one of the contactList objects?
I suppose I could do some back-end trickery, but I am looking for a front-end solution to this.
Don't use ?seq_contains for finding generic object at all. It doesn't call Object.equals, instead it works like the == operator of the template language, which only allows comparing strings, numbers, booleans and dates/times, otherwise it gives you an error. Unfortunately it won't fail in your case, because POJO-s are also strings (and their string value is what toString() returns). This is an unfortunate legacy of the stock ObjectWrapper (scheduled to be fixed in FM3); not even a quirk in the template language. Ideally you get an error there. Instead, now it silently compares the return value of the toString()-s...
Your data-model should already contain what the template should actually display. FTL is not a programming language, so if you try to extract that from the data-model in it, it will be a pain. But, that the data-model contains that data can also mean that some objects in the data-model have methods that extract the data you need. As a last resort, you can add objects that just contain helper methods.
Update: Returning to ?seq_contains, if you need the Java semantics and list is a Java Collection, you can just use the Java API: list?api.contains(contact).
Suppose I have a simple map, example-map:
(def example-map {"s" {"f" "g"}
"m" {"r" "q"}})
I can use clojure.data.json/write-str to JSON-ify this map as such:
(clojure.data.json/write-str example-map) =>
"{\"s\":{\"f\":\"g\"},\"m\":{\"r\":\"q\"}}"
I'd like to conditionally place some of the values into lists according to the value of their keys.
write-str provides an optional :key-fn, which applies some function to key value pairs. For example, the desired function might specify that all values associated with entries that match "s" are placed in lists.
(clojure.data.json/write-str example-map :key-function desired-function) =>
"{\"s\":[{\"f\":\"g\"}],\"m\":{\"r\":\"q\"}}"
Does anyone know how to specify such a key function that checks for membership of a key in a set and places the values associated with members into an array rendered in the output JSON?
Like your previous question, this is not a job for the JSON parser. You don't need to rely on write-time features of your JSON library to adjust the shape of your JSON maps. Instead, you have a fully functional Turing complete language at your disposal: Clojure! If the maps don't already look the way you want them to be output, then write a function that takes one Clojure map as input and produces a different one as output; then ask your JSON library to write the output map, without any special rules for fiddling with the output.
Now, as it happens this particular JSON library does provide an option named value-fn (not key-function as you claim) to let you modify a value in a map based on its key. So you could use that, in which case you simply need to write a function with a signature like:
(fn [k v]
(...compute new value...))
There are many ways you could write such a function, but they are all entirely divorced from your JSON parser. If you need help writing it, mention some specific things you need help with, so you can get a clear explanation for the part of the process that is actually giving you trouble.
I am trying to add data from the Scope to an Array.
In my example I have $scope.employee which have several other fields, like name, number, email, etc.
So when I push the data to the Array I use:
array.push($scope.employee);
This works, because it adds the data to the array, but the binding still applies, so if I later on change thing in the scope, the data in the array also changes. I want this array to be static and not change. Just to hold the elements I have passed into it.
I would like to only add the data from the $scope.employee and not the binding.
I know it's possible to:
array.push({name: $employee.name, number: $employee.number});
But the $scope.employee have many fields, therefore I want to push the whole object.
You want to use angular.copy to make a deep copy without the pointers.
array.push(angular.copy($scope.employee));

I know that you can pass data to a view using:
navigator.pushView(views.LoadoutView, list.selectedItem)
But what if I pass that data, and then want to pass another piece of data to the same view using a similar method?
Can I get/set a new property or can I write the current data to an xml file as soon as it is received?
Here is a little diagram I made of what I'm trying to achieve (I spent hours on it :P).
From what I've understood, you need to push multiple objects to a view at once, correct?
The data object can only be a single object or object reference, which means that if you want to push more than just your list.selectedItem, create a new Object (a generic one will do) that contains both your properties and push it, much like the following;
var myDataObject:Object = {firstPieceOfData:list.selectedItem, secondPieceOfData:yourSecondObjectHere};
navigator.pushView(views.LoadoutView, myDataObject);
