Prisma 读取数据 - 有没有更好的方法来读取嵌套数据？

Question

I currently need to pull lots of nested data to format into a JavaScript object to send into a chart as the data, I am currently allowing ten nested deep, but there might be some cases when this just keeps on going.

I'm wondering if there is a better way to pull out data like this, I couldn't see anything in the docs, for pulling infinitely or dynamically nested data through the relationships.

This is what I currently have for example:

const [result] = await prisma.company.findMany({
  where: {
    users: {
      some: {
        email: {
          contains: session.user.email,
        },
      },
    },
  },
  select: {
    name: true,
    users: true,
    id: true,
    profiles: {
      select: {
        id: true,
        name: true,
        image: true,
        category: {
          select: { name: true },
        },
        children: {
          select: {
            id: true,
            name: true,
            image: true,
            category: {
              select: { name: true },
            },
            children: {
              select: {
                id: true,
                name: true,
                image: true,
                category: {
                  select: { name: true },
                },
                children: {
                  select: {
                    id: true,
                    name: true,
                    image: true,
                    category: {
                      select: { name: true },
                    },
                    children: {
                      select: {
                        id: true,
                        name: true,
                        image: true,
                        category: {
                          select: { name: true },
                        },
                        children: {
                          select: {
                            id: true,
                            name: true,
                            image: true,
                            category: {
                              select: { name: true },
                            },
                          },
                        },
                      },
                    },
                  },
                },
              },
            },
          },
        },
      },
    },
  },
});

Have you considered using the include statement instead of select ? It automatically fetches all non-relation fields, so you just have to manually specify the relation fields. The nested reads section in the prisma docs also contains a lot of examples for this.

In general, if you don't need granular control over which fields of the model get returned from the query, include is the way to go.
