Note :- Adding user to database takes sometimes upto 15 seconds .

Features Implemented :-

User can fill the application form and their details are stored in MongoDB database .

User can select Payment method and click payment button

As told in assignment , CompletePayment method I have not Implemented but to mimic it I am fetching current user details and using it as response .

Showing response after payment as Transaction Summary .

Approach :-

Frontend built using ReactJS

Users fill application form and submit details to mongoDB with Key as PhoneNo to search & read .

If user is already regisetered then check for last start and wanted start date and if less than 30 then tell to come after .

After this choose Payment method and continue

Then get response as succesfull payment .

Assumptions :-

Implemented CompletePayment() as a post request and fetch , as given in assignment , not to implement it.

ER Diagram => We can add extra entity as Yoga_Class with attribute Fees and relation Enrolled_in But as fees is fixed therfore I used one entity only .

MongoDB Queries used :-

For storing :-

const PersonalDetails = new user({ // user is schema model

                "name":name,
                "age" : age,
                "phoneNo" : phoneNo,
                "startDate" : startDate,
                "batch" : batch
            })
    
            PersonalDetails.save()

For Updation :-

user.updateOne({phoneNo:phoneNo},{$set:{startDate:to_update}})

For Finding User :-

user.findOne({phoneNo:phoneNo})
