Cannot use 2 offset and cursor pagination at the same time

[ValentinVignal]

Describe the bug

I have an entity todo-item, and I'm trying to create 2 resolvers:

• An offset paginated one
• A cursor paginated one

Have you read the Contributing Guidelines?

Yes

To Reproduce Steps to reproduce the behavior:

1. Follow the steps to install the dependencies and create the example from https://tripss.github.io/nestjs-query/docs/introduction/example (or checkout https://github.com/ValentinVignal/reproducible/tree/ptc-org/nestjs-query/cursor-and-offset-pagination)
2. Update the todo item module resolvers to :

      resolvers: [
        {
          DTOClass: TodoItemDTO,
          EntityClass: TodoItemEntity,
          create: { disabled: true },
          update: { disabled: true },
          delete: { disabled: true },
          read: {
            one: { disabled: true },
            many: {
              name: 'todoItemCursor',
            },
          },
        },

        {
          DTOClass: TodoItemDTO,
          EntityClass: TodoItemEntity,
          pagingStrategy: PagingStrategies.OFFSET,
          create: { disabled: true },
          update: { disabled: true },
          delete: { disabled: true },
          read: {
            one: { disabled: true },
            many: {
              name: 'todoItemOffset',
            },
          },
        },
      ],

3. run npm run start

Expected behavior

I would want to have 2 resolvers, one with cursor pagination and one with offset pagination.

Current behavior

Instead I get the error:

/Users/valentin/Perso/Projects/reproducible/node_modules/graphql/type/schema.js:219
        throw new Error(
              ^

I tried to see if there was a way to give a custom name to the connections, but I couldn't find it. Maybe a connectionName parameter could be added somewhere so I could specify connectionName: 'TodoItemCusorConnection' and connectionName: 'TodoItemOffsetConnection'

[ValentinVignal]

I see it is possible to provide a connectionName to the ReadResolverOpts<DTO> :

          read: {
            connectionName: 'TodoItemOffsetConnection',
            one: { disabled: true },
            many: {
              name: 'todoItemOffset',
            },
          },

but it is being overridden in https://github.com/TriPSs/nestjs-query/blob/6f58030695cfb774d591cc2af2910ebc1e115f03/packages/query-graphql/src/resolvers/read.resolver.ts#L61

[ValentinVignal]

For the ones looking for a workaround, I managed to got both by doing:

 resolvers: [
        {
          DTOClass: TodoItemDTO,
          EntityClass: TodoItemEntity,
          create: { disabled: true },
          update: { disabled: true },
          delete: { disabled: true },
          read: {
            one: { disabled: true },
            many: {
              name: 'todoItemCursor',
            },
          },
        },
        {
          DTOClass: TodoItemDTO,
          dtoName: 'TodoItemOffsetPaginated',
          EntityClass: TodoItemEntity,
          pagingStrategy: PagingStrategies.OFFSET,
          create: { disabled: true },
          update: { disabled: true },
          delete: { disabled: true },
          read: {
            one: { disabled: true },
            many: {
              name: 'todoItemOffset',
            },
          },
        },
      ],

But I think this issue should stay open as connectionName doesn't seem to do anything because it always overridden

Hi @ValentinVignal, thanks for reporting, will try to check this out soon.

[ValentinVignal]

@TriPSs I wouldn't mind trying to work on this, I sent you a message for some help/advices

[TriPSs]

@ValentinVignal that would be awesome, thanks! Let me know if you need any help.

[ValentinVignal]

How should I contact you if I have some questions ?

[TriPSs]

You can comment here or if you have a more general question inside discussions, I receive emails for all notifications and tend to reply when I see them :)

[TriPSs]

@ValentinVignal FYI: I also created a slack (See README), let's see if that works.
