----------------------------------------
Summary: Writing non-flattened struct consts is not allowed
Key: THRIFT-3316
URL: https://issues.apache.org/jira/browse/THRIFT-3316
Project: Thrift
Issue Type: New Feature
Affects Versions: 0.9.2
Reporter: Motiejus Jakštys
Compiler does not allow to create const structs referring to other structs.
E.g.:
{code}
struct Book {
1: i32 id
}
struct Author {
1: Book book
}
const Book bookEx1 = { // example instance of Book
'id': 1
}
const Author AuthorEx1 = { // example instance of Author
//'book': { 'id': 1 } // This is a copy from above, but works well
'book': BookEx1 // this doesn't work, see below
}
{code}
When compiling, it gives the following error:
{code}
$ thrift -v -gen js:ts model.thrift
Scanning model.thrift for includes
Parsing model.thrift for types
[FAILURE:model.thrift:17] type error: const "AuthorEx1.book" was declared as
struct/xception
{code}
Problem: I want to refer to other defined const structs by already defined
structs from before (e.g. bookEx1) instead of flattening the values. Am I
missing something, or is this unsupported?
Use case: for every model, I am creating mock `const` values which the services
can re-use in their tests.
I asked this on stackoverflow too:
