【Prisma】条件判断中，数组包含如何进行判断？

The error occurs because you are using the has operator on a field typed as Json in your Prisma schema. In Prisma, the has operator is only available for Scalar Lists (native database arrays like Int[] or String[]).

For a Json field, the operator you are looking for is array_contains.

Here are the two ways to fix this:

Option 1: Use array_contains (If field remains Json)

If your ganyu_options field must stay as a Json type in your schema.prisma, change your code to this:

where: {
  OR: [
    { type: 1 },
    { 
      ganyu_options: { 
        array_contains: low_number // Use array_contains for Json fields
      } 
    },
  ],
  status: 1,
},

Note: array_contains works on PostgreSQL and MySQL (for JSONB/JSON columns).

Option 2: Change Schema to Scalar List (Recommended)

If ganyu_options is always going to be a list of numbers, it is better to define it as an array in your schema.prisma. This makes it type-safe and allows you to use the has operator.

1. Update your schema.prisma:

   model MiniArticle {
     id            Int    @id @default(autoincrement())
     // Change from Json to Int[]
     ganyu_options Int[]  
     status        Int
     type          Int
   }

   (Note: Native scalar lists like Int[] are supported out-of-the-box by PostgreSQL and CockroachDB. If you are using MySQL, you must stick with Option 1).

2. Run migration:

   npx prisma migrate dev

3. Your original code will now work:

   where: {
     OR: [
       { type: 1 },
       { ganyu_options: { has: low_number } }, // This works now!
     ],
     status: 1,
   },

Summary: Which one to choose?

• If using PostgreSQL and the data is always a list: Use Option 2 (Change to Int[]). It is faster and more type-safe.
• If using MySQL or the JSON structure is unpredictable: Use Option 1 (array_contains).
