Related queries enhancement

[karatakis]

PR Info

Make related queries to receive filtering, ordering and (memory) pagination

Example: Get all customers with their address and order (order amount grater than 8 sorted by amount descending, 1st item only)

{
  customer(
    filters: { active: { eq: 0 } }
    pagination: { cursor: { limit: 3, cursor: "Int[3]:271" } }
  ) {
    nodes {
      customerId
      lastName
      email
      address {
        address
      }
      payment(
        filters: { amount: { gt: "7" } }
        orderBy: { amount: ASC }
        pagination: { pages: { limit: 1, page: 0 } }
      ) {
        nodes {
          paymentId
          amount
        }
        pages
        current
        pageInfo {
          hasPreviousPage
          hasNextPage
        }
      }
    }
    pageInfo {
      hasPreviousPage
      hasNextPage
      endCursor
    }
  }
}

I wonder where is the recursion? And why increasing the limit convince Rust compiler?

[karatakis]

For more information about the recursion can be found here async-graphql/async-graphql#1125.

An idea is to generate a GraphQL connection node using derives

Hey @karatakis, could you help me resolve the merge conflict? Thanks!!

[billy1624]

Hey @karatakis, I want to double check, is this ready for review?

[karatakis]

@billy1624 its ready

[tyt2y3]

Wow, that's really sophisticated querying!
We should add test cases for new features, it will tell us when it breaks someday.

[karatakis]

I have to add some test cases and fix the self ref tests because now it returns a graphql connection node

[tyt2y3]

Cool! @billy1624 can review again?

[tyt2y3]

Okay, may be one dump question. Is Enchanted a typo of Enhanced or is it meant to be?

[billy1624]

Hey @karatakis, great work!! I got some refactoring. Please check

• Refactor: Related queries enchantments #101

[billy1624]

Hey @karatakis, feel free to merge! Nice work!

[karatakis]

Okay, may be one dump question. Is Enchanted a typo of Enhanced or is it meant to be?

Typo! Its an old habit from too many RPGs in the past.
