How to create a credit plan where I want to provide credits to multiple user features

I have app which has multiple features . So if he purchase one time credit, the credit amounts for feature 1 should increase by 10, feature 2 by 20 and feature 3 by 30. This because some feature are costly as they use dependent services and other feature we want to limit so that they don't abuse the system.

Hi @p4j4r5. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Based on the information provided in the knowledge sources, you can create a credit system by using Stripe for payments and updating the user's credit balance in your Wasp application. However, the knowledge sources do not provide a direct solution for assigning different credit amounts to different features. Here's a general approach you could take: 1. Create different Stripe products for each feature. Each product would represent a different amount of credits. 2. In your Wasp application, handle the Stripe webhook events for successful payments. In the event handler, check the purchased product ID and update the user's credit balance for the corresponding feature. Here's an example of how you might update a user's credit balance in Wasp, based on the knowledge sources:

if (line_items?.data[0]?.price?.id === process.env.CREDITS_PRICE_ID) {
  console.log('Credits purchased: ');
  await context.entities.User.updateMany({
    where: {
      stripeId: userStripeId,
    },
    data: {
      credits: {
        increment: 10, // Update this value based on the purchased product
      },
    },
  });
}

if (line_items?.data[0]?.price?.id === process.env.CREDITS_PRICE_ID) {
  console.log('Credits purchased: ');
  await context.entities.User.updateMany({
    where: {
      stripeId: userStripeId,
    },
    data: {
      credits: {
        increment: 10, // Update this value based on the purchased product
      },
    },
  });
}

Please note that this is a simplified example and you would need to adjust it to fit your application's needs. For example, you might need to store separate credit balances for each feature in your user model. For more detailed information, you might find it helpful to review the Wasp documentation (https://wasp-lang.dev/docs) or ask for help in the Wasp Discord community (https://discord.com/channels/686873244791210014/1205328655300038766). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ---------------------- Sorry @p4j4r5, I seem to be having a bit of trouble. Don't worry though, I've pinged my support and they will try to fix me up! :technologist: Perhaps try again in 15mins?

Having different plan for different feature isn't desirable. As User have to pay many times to get to use features.

@Vinny (@Wasp) I think one for you 😄

It sounds like you'd want to add some extra relations to your database and user model, e.g. model featureCredits. @kapa.ai could you show us how this might look in the database? we want the featureCredits model to have 3 features and when a user purchases the main plan it increments featureOne by 10, featureTwo by 20, and featureThree by 30.

Let me check the knowledge base for you. One moment! :books: ---------------------- Sure, you can create a new entity FeatureCredits and establish a one-to-one relation with the User entity. Here's an example of how you might define these entities in your Wasp code:

entity User {
  id Int @id @default(autoincrement())
  featureCredits FeatureCredits @relation(fields: [featureCreditsId], references: [id])
  featureCreditsId Int
  // Other fields...
}

entity FeatureCredits {
  id Int @id @default(autoincrement())
  featureOne Int @default(0)
  featureTwo Int @default(0)
  featureThree Int @default(0)
  user User @relation(fields: [userId], references: [id])
  userId Int
}

entity User {
  id Int @id @default(autoincrement())
  featureCredits FeatureCredits @relation(fields: [featureCreditsId], references: [id])
  featureCreditsId Int
  // Other fields...
}

entity FeatureCredits {
  id Int @id @default(autoincrement())
  featureOne Int @default(0)
  featureTwo Int @default(0)
  featureThree Int @default(0)
  user User @relation(fields: [userId], references: [id])
  userId Int
}

In this example, each User has a FeatureCredits object associated with it. The FeatureCredits entity has fields for featureOne, featureTwo, and featureThree, which represent the user's credit balance for each feature. When a user purchases the main plan, you can increment the credit balances like this:

if (line_items?.data[0]?.price?.id === process.env.CREDITS_PRICE_ID) {
  console.log('Credits purchased: ');
  await context.entities.FeatureCredits.updateMany({
    where: {
      userId: userStripeId,
    },
    data: {
      featureOne: {
        increment: 10,
      },
      featureTwo: {
        increment: 20,
      },
      featureThree: {
        increment: 30,
      },
    },
  });
}

if (line_items?.data[0]?.price?.id === process.env.CREDITS_PRICE_ID) {
  console.log('Credits purchased: ');
  await context.entities.FeatureCredits.updateMany({
    where: {
      userId: userStripeId,
    },
    data: {
      featureOne: {
        increment: 10,
      },
      featureTwo: {
        increment: 20,
      },
      featureThree: {
        increment: 30,
      },
    },
  });
}

ok @p4j4r5 Kapa bot provided a good answer above, but instead of defining them as entity User {} and entity FeatureCredits you want to define them in your schema.prisma as model User { } and model FeatureCredits { }
