Run query from Postman

Hi guys. First of all, congrats for this very useful lib.

I wrote a very basic mutation for file upload:

class TestMutation(graphene.Mutation):
    class Arguments:
        sql_file = Upload()

    Output = OperationStatusRetType

    def mutate(self, info, sql_file_ref):
            sql_file = info.context.FILES.get(sql_file_ref)
            sql_query_template = sql_file.read().decode('utf-8')
            sql_file_names = sql_file.names
            in_memory_file = io.StringIO(sql_query_template)
            put_s3_object(s3, AWS_DEFAULT_S3_BUCKET, in_memory_file.getvalue(), sql_file_names.split('/')[-1])

        return AddDatasetRetType(sqlFilePath=sql_file_names.split('/')[-1],
                                 operationStatus=OperationStatusRetType(success=True))

and I consume it this way:

mutation Test {
  testMutation(sql_file: "test.png") {
    success
    error
  }
}

I would like to test it with Postman, posting the file using the POST form-data option, like in the pic:

but I get the error “Must provide query string” as generally in GraphQL the querystring should be in the form body.

In the headers “Content-Type” is “application/graphql”.

Do you know how I can test my GraphQL endpoint using Postman? Also is still not clear to me if I need to assign a value to the Upload field (“sql_file” in this case) or it can be left empty.

Thanks

@gj1118 looks like you put the operations field in the name section of the file. If we’re following the example verbatim in insomnia, you’ll need to do a multipart post with 3 parameters:

1. A field named operations with the value {"query": "mutation ($file: Upload) { myUpload(fileIn: $file) { ok }}", "variables": { "file": null }}
2. A field named map with the value { "0": ["variables.file"]}
3. A file field named 0 with the file you’re uploading set as the value

Ah sorry, didn’t read the entire thing. Since postid is a string, you’ll need to change the postid variable in the operations from null to the string you want, and you can remove all references to “1”
