In clojure, how can I access and return a modified version of this collection












0















If I have a collection like this ({:A 1 :B 2 :Goal 5} {A:2 :B 4 :Goal 2}) is there a way I can iterate through the it and use assoc to change all :Goal to some other value, say 0?
So basically given the collection above and the key :Goal the function returns ({:A 1 :B 2 :Goal 0} {A:2 :B 4 :Goal 0})



Any help is appreciated.



Thanks

          (let [A '({:A 1 :B 2 :Goal 5} {:A 2 :B 4 :Goal 2})]
          
    (map #(assoc % :Goal 0) A))


          or, if you are keen to use specter:



          (let [A '({:A 1 :B 2 :Goal 5} {:A 2 :B 4 :Goal 2})]
          
    (setval [ALL :Goal] 0 A))

                    Run scheduled task as local user group (not BUILTIN)

                    0 I am trying to run a scheduled task with User Group (not a single user). This is working fine when I in the field "when running a task, use the following user account:" insert BUILTIN User Group (for example: Administrators or Users). But when I try it with the created Local User Group (example: TestGroup) it is not working. The Users in the TestGroup are the same as in the Administrators group. What could be the problem? Are there some restrictions to the Created User Group compared to BUILTINUsers? scheduled-tasks taskscheduler windowstaskschedule share | improve this question asked Nov 15 '18 at 15:36 Far...
