How to pass a variable value from computed to template in vue?

Question

I have a json response, where in 'products' I have 'funds' and inside funds I have a date field. i want to view the date in template.

I have used forEach for iterating the products and then iterated the funds, then assigned the date to a variable. This is done inside the computed().

Now i want the date to be fetched in the template. But I am not able to fetch it.

I have tried adding the same in methods(), but no success

data: function(){
    return {
        date: ''
    }
},


computed: {
        products: function(){
            let products = this.sortedSchemeData.products;
            var year = this.selectedSchemeYear;

            products.forEach(function(product){

            product.funds.forEach(function(fund){
                   var date = fund.fundsProcessDate;
               console.log(date); //some date from json

                })
            });

            return products;
        }
    },


<template>
<div>
<p>date: <b>{{date}}</b></p>
</template>

date: date in json

Answer 1

The products[0].funds[0].fundProcessDate doesn't handle the case when the first product is empty. My example below does handle it.

computed: {
    date() {
      const found = this.products.find(product =>
        product.funds.some(fund => fund.fundsProcessDate != null)
      );
      return (found && found.funds[0].fundsProcessDate) || "01-01-2019"; //default date if not found from all of them
    }
}

You can use Computed-Setter for this scenario.

data: function(){
    return {
        date: ''
    }
},
    
computed: {
        products: {
        // setter
          set: function (newValue) {
            let products = newValue;
            var year = this.selectedSchemeYear;

            products.forEach(function(product){
              product.funds.forEach(function(fund){
                   this.date = fund.fundsProcessDate;
                })
              });
            }
          }
        },

<template>
<div>
<p>date: <b>{{date}}</b></p>
</template>
