Calculer une expression Arcade dans les formulaires de Map Viewer

LJackson29

Bonjour -

Je débute encore avec Arcade et j’aurais besoin d’aide pour comprendre ce qui ne va pas dans l’expression ci-dessous. J’ai 4 questions (voir image 1). Les questions 1 et 4 reçoivent toujours une réponse. Les questions 2 et 3 dépendent d’une autre question qui indique si le projet est une solution technique ou naturelle. Si la réponse est « Technique », la personne répond à la question 2 ; si elle répond « Naturelle », elle répond à la question 3. Une logique permet de modifier les questions en fonction de la réponse initiale. Chaque réponse reçoit un score de 0, 10 ou 20. Nous attribuons ensuite des points bonus (question « Score maximal possible » dans l’image) en fonction du nombre de questions ayant obtenu 20 points, à l’aide de la logique ci-dessous (image 2). Mon code ne renvoie aucun nombre dès qu’une question obtient 20 ; si toutes les notes sont < 20, il renvoie correctement 0. Quelqu’un peut-il me dire ce que je fais mal ?

//tous au maximum

if ($feature.PR_RESF1_SCORE==20 && $feature.PR_RESF2ENG_SCORE==20 && $feature.PR_RESF3_SCORE==20) { //Tous au maximum - solution technique

return 20;

} else if ($feature.PR_RESF1_SCORE==20 && $feature.PR_RESF2NAT_SCORE==20 && $feature.PR_RESF3_SCORE==20) { //Tous au maximum - solution naturelle

return 20;

//2 sur 3 au maximum

} else if ($feature.PR_RESF1_SCORE==20 && $feature.PR_RESF2ENG_SCORE==20 && $feature.PR_RESF3_SCORE<20) { //RF1 et 2 au maximum - solution technique

return 10;

} else if ($feature.PR_RESF1_SCORE==20 && $feature.PR_RESF2NAT_SCORE==20 && $feature.PR_RESF3_SCORE<20) { //RF1 et 2 au maximum - solution naturelle

return 10;

} else if ($feature.PR_RESF1_SCORE==20 && $feature.PR_RESF2ENG_SCORE<20 && $feature.PR_RESF3_SCORE==20) { //RF1 et 3 au maximum - solution technique

} else if ($feature.PR_RESF1_SCORE==20 && $feature.PR_RESF2NAT_SCORE<20 && $feature.PR_RESF3_SCORE==20) { //RF1 et 3 au maximum - solution naturelle

} else if ($feature.PR_RESF1_SCORE<20 && $feature.PR_RESF2ENG_SCORE==20 && $feature.PR_RESF3_SCORE==20) { //RF2 et 3 au maximum - solution technique

return 10;

} else if ($feature.PR_RESF1_SCORE<20 && $feature.PR_RESF2NAT_SCORE==20 && $feature.PR_RESF3_SCORE==20) { //RF2 et 3 au maximum - solution naturelle

return 10;

//1 sur 3 au maximum

} else if ($feature.PR_RESF1_SCORE==20 && $feature.PR_RESF2ENG_SCORE<20 && $feature.PR_RESF3_SCORE<20) { //RF1 seul au maximum - solution technique

return 5;

} else if ($feature.PR_RESF1_SCORE==20 && $feature.PR_RESF2NAT_SCORE<20 && $feature.PR_RESF3_SCORE<20) { //RF1 seul au maximum - solution naturelle

return 5;

} else if ($feature.PR_RESF1_SCORE<20 && $feature.PR_RESF2ENG_SCORE==20 && $feature.PR_RESF3_SCORE<20) { //RF2 seul au maximum - solution technique

return 5;

} else if ($feature.PR_RESF1_SCORE<20 && $feature.PR_RESF2NAT_SCORE==20 && $feature.PR_RESF3_SCORE<20) { //RF2 seul au maximum - solution naturelle

return 5;

} else if ($feature.PR_RESF1_SCORE<20 && $feature.PR_RESF2ENG_SCORE<20 && $feature.PR_RESF3_SCORE==20) { //RF3 seul au maximum - solution technique

return 5;

//Aucune note maximale

} else if ($feature.PR_RESF1_SCORE<20 && $feature.PR_RESF2ENG_SCORE<20 && $feature.PR_RESF3_SCORE<20) { //Aucune note maximale - solution technique

return 0;

} else if ($feature.PR_RESF1_SCORE<20 && $feature.PR_RESF2NAT_SCORE<20 && $feature.PR_RESF3_SCORE<20) { //Aucune note maximale - solution naturelle

return 0;

@JoshuaSharp-Heward Thanks for your assistance on this - I really appreciate it. Knowing that you could get it to run, I started tracing back my steps and finally found the root cause. The Score fields are all short integers, but are calculated based upon select one questions. In those calculation scripts I had my numbers in single quotes which was causing the problem.

if ($feature.PR_RESF1=='1. RSS asset(s) BRE meet ALR'){

return '0';

I removed the single quotes, and the script is now working as expected :-). Being new to Arcade, I have to say I do not know when to use double quotes, single quotes or no quotes. It is often trial by error, but in this case the calculations for the score fields were running as expected and returning the correct values, so I did not know the single quotes were problematic.

Thanks again!

Hi,

I've gone for a slightly different approach to the problem as I think with that many if/else if clauses it can be tricky to work out what's going on.

var RESF1Score = $feature.PR_RESF1_SCORE
var RESF2Score = $feature.PR_RESF2ENG_SCORE + $feature.PR_RESF2NAT_SCORE
var RESF3Score = $feature.PR_RESF3_SCORE

function isTwenty(i) { return i == 20 }

var num20s = Count(Filter([RESF1Score, RESF2Score, RESF3Score], isTwenty)
When(num20s==3,20,num20s==2, 10, num20s==1, 5, 0)

To summarise what this is doing:

Adds ENG/NAT together as one is filled in each time and the other is 0, for the purposes of this calculation I believe they can be lumped together because ENG and NAT are treated equally
Assigns a variable for the above plus the RESF1 and RESF3 score
Create a function that returns true if the input is equal to 20
Uses the Arcade Filter function with the list of scores from above, to get rid of any that aren't 20, and returns the count of the number of 20s
Uses the When function to return the 20 if there are 3 20s, 10 if there are 2, 5 if there's 1 and 0 if there are none

Hope this works for you! Seemed to be working fine in the Arcade playground for me.

Cheers,

Josh

Hi @JoshuaSharp-Heward -

Sorry for the slow reply, I am just getting back to this after getting pulled away on another project. I need to get the default values updated in my layer, and then I will see if this works.

Many thanks!

Leila

Hi Leila,

No worries, let me know how you get on 🙂

@JoshuaSharp-Heward I was able to test your code today, and it too only returns 0 for some reason. I also tried a hybrid script posted below with the same result. It seems like all of these should work - I feel like I am missing something really obvious. I cleared the entire "Highest" field to Null to make sure there wasn't lingering data in there and that the scripts were actually calculating, and they are, just to 0 always. The score fields are all short integers.

Thanks!

Leila

Hybrid script

var RESF1Score = $feature.PR_RESF1_SCORE

var RESF2Score = $feature.PR_RESF2ENG_SCORE + $feature.PR_RESF2NAT_SCORE

var RESF3Score = $feature.PR_RESF3_SCORE

//all highest

if (RESF1Score==20 && RESF2Score==20 && RESF3Score==20) { //All highest

return 20;

//2 of 3 highest

} else if (RESF1Score==20 && RESF2Score==20 && RESF3Score!=20) { //RF1 and 2 highest

return 10;

} else if (RESF1Score==20 && RESF2Score!=20 && RESF3Score==20) { //RF1 and 3 highest

return 10;

} else if (RESF1Score!=20 && RESF2Score==20 && RESF3Score==20) { //RF2 and 3 highest

return 10;

//1 of 3 highest

} else if (RESF1Score==20 && RESF2Score!=20 && RESF3Score!=20) { //only RF1 highest

return 5;

} else if (RESF1Score!=20 && RESF2Score==20 && RESF3Score!=20) { //only RF2 highest

return 5;

} else if (RESF1Score!=20 && RESF2Score!=20 && RESF3Score==20) { //only RF3 highest

return 5;

//None are highest

} else if (RESF1Score!=20 && RESF2Score!=20 && RESF3Score!=20) { //none are highest

return 0;

}
