Swagger-editor: Using $ref in array query parameter

[alecmev]

Swagger File

swagger: '2.0'
info:
  title: snip

• Version: 2.10.3

Issue

Given the file above, I get the following error:

If I replace

$ref: '#/definitions/SomeDef'

with plain

type: integer
format: int32

then the error goes away. Judging by Response Object Examples in the spec (not the same, but related), it should be okay to use $ref in this context. Is my assumption wrong, or is this a bug?

[webron]

You cannot use $ref's in any way under non-body parameters, not directly and not for arrays. You'd have to define it all inline. This changes in the next version of the spec.

i got this error

but fields are work fine

Can you help me with this?

Can i describe array of objects in form data request in current version of swagger?

[webron]

@gjorgic - today, you'd need to declare those explicitly. So you'd need to create a parameter with the name contact[0][name]. In the next version there will be better support for it, but I'm not sure it will fully cover your use case.

[elharony]

I wonder; Is there a reason for not allowing $ref in array in a non-body parameter @webron ?
