To add a field to a model in Prisma GraphQL, you'll need to update the schema.prisma file, which defines your database models, fields, and relationships. Here's a step-by-step guide on how to add a field to a model in Prisma:

  1. Open your schema.prisma file in your project directory.
  2. Locate the model to which you want to add a new field. Models are defined using the model keyword followed by the model name in camelCase.
  3. Inside the model block, add a new field definition using the desired field name followed by the field type. For example, to add a field named newField with type String to the User model, you would add the following line:
1
newField String


  1. Save the changes to the schema.prisma file.
  2. Run the Prisma migration tool to apply the changes to your database. You can do this by running the following command in your terminal:
1
npx prisma migrate dev --name add-new-field


Replace add-new-field with a descriptive name for the migration.

  1. After the migration is completed, you can regenerate your Prisma client to update the generated code based on the new schema. Run the following command in your terminal:
1
npx prisma generate


  1. Finally, make sure to update your GraphQL resolver functions to handle the new field, if necessary.


That's it! You have successfully added a new field to a model in Prisma GraphQL.
