I want to create Product Categories , so i handle it in productController
class database call in productCatService
class. I added JS promise to this . now it gives following error.
productCatController.js
module.exports.createProductCat = async (request, response)=> {
let result = await productCatService.createProductCat(productCatData);
if (result) {
responseService.successWithData(response, "Product Category Created");
} else {
responseService.errorWithMessage(response, result);
}
}
productCatService.js
module.exports.createProductCat = (productCatData) => {
let productCat = {
name: productCatData.name,
desc: productCatData.desc,
count:productCatData.count,
status : productCatData.status
};
return new Promise((resolve,reject)=>{
ProductCategory.create(productCat).then(result => {
resolve(true);
}).catch(error => {
reject(false)
})
});
}
