in a template events function I have to do the following steps in order to get a ranked list of results:
1.call the asynchronous function userTaxonomyProducts, that gives as a result the object Taxonomyproducts
2. use and handle the object Taxonomyproducts to conclude in a new object Taxonomyproducts_attributes that will be used in step 3 as an argument to the second async function call search_for_products
3. call the async function search_for_products
with the use of promises I can get the results of steps 1 and 3 but I am not sure how I should handle the step 2 should I create another async function and call it between steps 1 and 3 or is there an easiest way that I can handle the result of the async function.
My code looks like below:
Template.product_selection.events({
‘click #show_products’: async function(event,instance) {
event.preventDefault();
instance.state.set(‘show_products’, true);
......
promise=new Promise((resolve, reject)=>{
userTaxonomyProducts(params1,(Taxonomyproducts) =>{
resolve(Taxonomyproducts);
})
})
promise_ranked=new Promise((resolve, reject)=>{
search_for_products(params2,Taxonomyproducts_attributes,(Products) =>{
resolve(Products);
})
})
//step 1
const Taxonomyproducts=await promise
console.log("Taxonomyproducts",Taxonomyproducts )
//step 2
INGR_1=[]
INGR_2=[]
INGR_3=[]
INGR_4=[]
for (i=0;i++;i<Taxonomyproducts.length){
const Taxonomyproducts_attributes={
"INGR_1":INGR_1.push(Taxonomyproducts[0].Offerings[0]),
"INGR_2":INGR_2.push(Taxonomyproducts[0].Offerings[1]),
"INGR_3":INGR_3.push(Taxonomyproducts[0].Offerings[2]),
"INGR_4":INGR_4.push(Taxonomyproducts[0].Offerings[3])
}
console.log("Taxonomyproducts_attributes",Taxonomyproducts_attributes)
}
//step 3
const rankedProducts=await promise_ranked
console.log(“rankedProducts”,rankedProducts)
Session.set(“recommendedProducts”,rankedProducts);
}})
and the problem is that step 2 gets undefined so I cannot further use it to call the step 3 as I should
