Not able to assign JSON data from a service directly to the items variable.
I am not able to assign JSON data from a service directly to the items variable. It should accept any array of objects. If I do, the drop down shows all names as [object object]. In the Demo Application, there was a exported const array that was assigned. Would have to do the same to be able to display the data correctly?
[object object] indicate you ask a complex object to be displayed. Check textField parameter correspond to a property of your object you want to display
[ { "data": { "branchID": 13, "branchName": "Hyderabad", "branchCode": "Hyd", "parentBranchId": null, "currentBranchId": null, "treeLevel": null } } ]
Above is the data I have and the tag attribute I have given is like this: textField="data.branchName".
I have multiple levels in the data. The number of levels are shown perfectly, but the text is shows as [object object]
I'm not convinced path is well handled in text or id field property, never test this case. Finally, I call something like item[textField] to get value (item["data.branchName"] in your case), I think js don't handle this correctly.
The solution doesnt work.
My data is as below:
this.branches =[ { "data": { "branchID": 15, "branchName": "kachigoda", "branchCode": "kachi", "parentBranchId": null, "currentBranchId": null, "treeLevel": null }, "children": [ { "data": { "branchID": 18, "branchName": "uppal", "branchCode": "upl", "parentBranchId": null, "currentBranchId": null, "treeLevel": null }, "children": [ { "data": { "branchID": 19, "branchName": "chiluka Nagar", "branchCode": "upl", "parentBranchId": null, "currentBranchId": null, "treeLevel": null }, "children": [ { "data": { "branchID": 20, "branchName": "MalliKarjuna Nagar", "branchCode": "M N", "parentBranchId": null, "currentBranchId": null, "treeLevel": null }, "children": [] } ] } ] } ] } ]
And as suggested, I have given it like this in my template:
<tree-select name="Branch" [items]="branches" textField="branches['data.branchName']" childrenField="children"
Doesnt work.
The package is very confined and takes data if it is only in the format that you have provided. any change in nesting and naming convention {"id":03,name:"India"} seems to be compulsory after a lot of testing.
There seems to be other workaround other than rearranging the data to be in the same format as your demo has used.
