How to Automatically Create Default Values in a Related Table on User Signup?

Version: 0.13.2 I'm building a project using Wasp-lang where I need to automatically create default entries in a Priority table whenever a user signs up via Google Auth (no custom fields). Specifically, when a new user is registered, I want to insert predefined rows in the Priority table linked to that user. What is the recommended approach for implementing this logic in Wasp-lang following best practices? Should I use a signup hook, or is there another method I should consider? Any advice on structuring this feature would be greatly appreciated!

Hi @IT Father. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- In Wasp, you can customize the signup process to include additional logic such as creating default entries in a related table. This can be achieved by creating a custom signup action. Here's a step-by-step guide on how you can do this: 1. Define the User Entity: First, you need to define the User entity in your main.wasp file. This entity can be as simple as including only the id field. You can add more fields as per your requirements. Here's an example of how you can define the User entity:

entity User {=psl  
 id Int @id @default(autoincrement())  
 // Add your own fields below  
 // ...  
psl=}

entity User {=psl  
 id Int @id @default(autoincrement())  
 // Add your own fields below  
 // ...  
psl=}

This action will be responsible for creating a new user and also creating default entries in the Priority table. Here's an example of how you can define a custom signup action:

action customSignup {  
 fn: import { signup } from "@src/auth/signup.js",  
}

action customSignup {  
 fn: import { signup } from "@src/auth/signup.js",  
}

Source (https://wasp-lang.dev/docs/auth/email#creating-a-custom-sign-up-action) In the signup.js file, you can define the signup function which will handle the user registration and also the creation of default entries in the Priority table. Please note that the actual implementation of the signup function and the logic for creating default entries in the Priority table is not provided in the knowledge sources. You would need to implement this logic based on your application's requirements. 3. Use the Custom Signup Action: Finally, you need to use the custom signup action in your application. You can do this by specifying the custom signup action in the methods field of the auth object in your main.wasp file. Here's an example:

app myApp {  
 // ...  
 auth: {  
 userEntity: User,  
 methods: {  
 usernameAndPassword: {  
 userSignupFields: import { userSignupFields } from "@src/auth/signup",  
 },  
 },  
 onAuthFailedRedirectTo: "/login",  
 },  
}

app myApp {  
 // ...  
 auth: {  
 userEntity: User,  
 methods: {  
 usernameAndPassword: {  
 userSignupFields: import { userSignupFields } from "@src/auth/signup",  
 },  
 },  
 onAuthFailedRedirectTo: "/login",  
 },  
}

Source (https://wasp-lang.dev/docs/auth/overview#1-defining-extra-fields) This way, whenever a new user signs up, your custom signup action will be invoked, which will create a new user and also create default entries in the Priority table. Remember to validate the data sent from the client and save the data to the database. Wasp knows how to do this once you've defined the fields. Source (https://wasp-lang.dev/docs/auth/overview#1-defining-extra-fields) I hope this helps! Let me know if you have any other questions. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ---------------------- Sorry @IT Father, 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?

I'd recommend using onAfterSignup hook 🙂 but for that you'll need Wasp 0.14.0 🙂
