How to update a record and delete that same record before update (nest js & mongoDB)

umasankar-swain — Wed, 19 Oct 2022 06:22:14 +0000

I want to update a record by its id but before update, i want to delete the previously stored data on that same record.What would be the process?

controller.ts

   public updateVendorServiceSpecialPrice = async (req: Request, res: Response, next: NextFunction): Promise<Response | void> => {
    try {
        if (req.body.vendorServiceId!='') {
            let results = await this.ServicesService.updateVendorServicesSpecialPrice(req.params.vendorServiceId, req.body);
            if (results != false) {
                this.success(res, 'Updated Successfully', 200, results._id);
            }
        } 
        return await this.error(res, 'Something Went Wrong!.', 500);
    } catch (e) {
        next(e)
    }
}

service.ts

    public async updateVendorServicesSpecialPrice(
    vendorServiceId: any,
    data: any
): Promise<any | Error> {
    try {
        return new Promise((resolve, reject) => {
            vendorServiceSpecialPriceSchema.findByIdAndUpdate(
                vendorServiceId,
                { ...data },
                (err: any, success: any) => {
                    if (err) {
                        reject(err);
                    }
                    if (!success) {
                        resolve(false);
                    } else {
                        resolve(success);
                    }
                }
            );
        });
    } catch (e) {
        console.log('service error\n', e);
        throw e;
    }
}

I am trying in this way to solve this,may be I am wrong,what would br the right process:

    public async updateVendorServicesSpecialPrice(
    vendorServiceId: any,
    data: any
): Promise<any | Error> {
    try {
        return new Promise((resolve, reject) => {
            vendorServiceSpecialPriceSchema.deleteOne({vendorServiceId})
            vendorServiceSpecialPriceSchema.findOneAndUpdate(
                vendorServiceId,
                { ...data },
                { returnNewDocument: true },
                (err: any, success: any) => {
                    if (err) {
                        reject(err);
                    }
                    if (!success) {
                        resolve(false);
                    } else {
                        resolve(success);
                    }
                }
            );
        });
    } catch (e) {
        console.log('service error\n', e);
        throw e;
    }
}

Thanks for your time....

How to check any property of State has any null value or not

umasankar-swain — Fri, 07 Oct 2022 06:24:24 +0000

Here is the state of my App:

const [state, setState] = useState({
    priceType: 0,
    recurrenceType: 0,
    start_date: '',
    end_date: '',
    minCapacity: 0,
    maxCapacity: 0,
    price: 0,
    min: 0,
    max: 0,
    days: []
});

Here is the code of condition in which I am trying to achive, if any property of the state has null value then return true otherwise return false.

const isNullish = Object.values(state).every(value => {
        if (value==='' && value===0 && value === []) {
          return true;
        }
        return false;
      });
console.log(isNullish)
console.log(state)

But the chalenge is whenever I execute that code in my app it returns false although the properties has no value.Below is the console output of above code:

false
SpecialPrice.jsx:124 {priceType: 0, recurrenceType: 0, start_date: '', end_date: '', 
minCapacity: 0, …}
days: []
end_date: ""
max: 0maxCapacity: 0
min: 0
minCapacity: 0
price: 0
priceType: 0
recurrenceType: 0
start_date: ""
[[Prototype]]: Object
SpecialPrice.jsx:129 []

For better understanding I have attached a screenshot here:

Thanks in advance....
