Topic: datatable rows refresh manually
ozgehan premium asked 5 years ago
Hi, I have a mdb-datatable on my page. I am using my own services to get data from api. I am expecting that when I change the row array of datatable, it should change its data.
But now I have a datatable object like below
fieldList: {
columns: [
{
label: "Name",
field: "name",
sort: "asc"
},
{
label: "Area",
field: "area",
sort: "asc"
},
{
label: "Neighborhood Name",
field: "neighborhoodName",
sort: "asc"
},
{
label: "Block No",
field: "blockNo",
sort: "asc"
},
{
label: "Parcel No",
field: "parcelNo",
sort: "asc"
}
],
rows: []
}
and after a new request sent when I try to re initialize rows like
this.fieldList.rows = [];
or
this.fieldList.rows = new Array();
or assign it to computed variable etc. nothing works with re-assigning it with new data that I get from api manually. It doesn't show any data only thing working is to go with for loop and remove existing data and re-push it with new one.
for(let i=0;i<ths.fieldList.rows.length;i++){
ths.fieldList.rows.pop();
}
ths._.forEach(response.data.data, item => {
ths.fieldList.rows.push(item);
});
Then it works like a charm. I am not sure this solution will give me any problems further but for now I am wondering why can't I change datatable row data by myself without reactive tag or pressing a refresh button (which is send requesst by itself which I don't want datatable to do it)
Thanks,

The problem is connected with the reactivity issue in Vue globally. Please read the following article and consider a new way of overwriting the array or object with your data: https://vuejs.org/v2/guide/reactivity.html#Change-Detection-Caveats
