I Have the Following Prisma Model For Product Categories
model ProductCategory {
categoryId Int @id @default(autoincrement())
categoryName String @db.VarChar(50)
slug String @db.VarChar(50)
parent ProductCategory? @relation("Subcategories", fields: [parentId], references: [categoryId])
parentId Int?
subcategories ProductCategory[] @relation("Subcategories")
}and this is How i Select The Categories
const data = await prisma.productCategory.findMany({
select: {
categoryId: true,
categoryName: true,
slug: true,
subcategories: {
select: {
categoryId: true,
categoryName: true,
slug: true,
subcategories: {
select: {
categoryId: true,
categoryName: true,
slug: true,
},
},
},
},
},
});And this is the Result
{
"categoryId": 10,
"categoryName": "Main Category",
"slug": "main-category",
"subcategories": [
{
"categoryId": 11,
"categoryName": "Sub Category",
"slug": "sub-category",
"subcategories": [
{
"categoryId": 12,
"categoryName": "Sub Category 1",
"slug": "sub-category-1"
},
{
"categoryId": 13,
"categoryName": "Sub Category 2",
"slug": "sub-category-2"
}
]
}
]
},
{
"categoryId": 11,
"categoryName": "Sub Category",
"slug": "sub-category",
"subcategories": [
{
"categoryId": 12,
"categoryName": "Sub Category 1",
"slug": "sub-category-1"
},
{
"categoryId": 13,
"categoryName": "Sub Category 2",
"slug": "sub-category-2"
}
]
},
{
"categoryId": 12,
"categoryNameE": "Sub Category 1",
"categoryNameD": "Sub Category 1",
"categoryNameP": "Sub Category 1",
"slugE": "sub-category-1",
"subcategories": []
},
{
"categoryId": 13,
"categoryNameE": "Sub Category 2",
"categoryNameD": "Sub Category 2",
"categoryNameP": "Sub Category 2",
"slugE": "sub-category-2",
"subcategories": []
}I Want the Result Like in the First Row and not want to have the other Rows because its again display the Sub Category Inside {Sub Category 1 ,Sub Category 2} and at the end Each Sub Category 1 and Sub Category 2 separately I want Result Like this
{
"categoryId": 10,
"categoryName": "Main Category",
"slug": "main-category",
"subcategories": [
{
"categoryId": 11,
"categoryName": "Sub Category",
"slug": "sub-category",
"subcategories": [
{
"categoryId": 12,
"categoryName": "Sub Category 1",
"slug": "sub-category-1"
},
{
"categoryId": 13,
"categoryName": "Sub Category 2",
"slug": "sub-category-2"
}
]
}
]
},Maybe something like this:
const data = await prisma.productCategory.findMany({
where: {
parentId: null // Not 100% sure, but something similar to this if it doesn't work
},
select: {
//...
},
});
basically, you want to fetch all categories that do not have a parent ID, or in other words, only the TOP level categories.
