I wanted to update a nested list but I experience a strange behavior where I have to call method twice to get it done...
Here is my POJO:
@Document(collection = "company")
data class Company (
val id: ObjectId,
@Indexed(unique=true)
val name: String,
val customers: MutableList<Customer> = mutableListOf()
//other fields
)
Below is my function from custom repository to do the job which I based on this tutorial
override fun addCustomer(customer: Customer): Mono<Company> {
val query = Query(Criteria.where("employees.keycloakId").`is`(customer.createdBy))
val update = Update().addToSet("customers", customer)
val upsertOption = FindAndModifyOptions.options().upsert(true)
//if I uncomment below this will work...
//mongoTemplate.findAndModify(query, update, upsertOption, Company::class.java).block()
return mongoTemplate.findAndModify(query, update, upsertOption, Company::class.java)
}
In order to actually add this customer I have to either uncomment the block call above or call the method two times in the debugger while running integration tests which is quite confusing to me
Here is the failing test
@Test
fun addCustomer() {
//given
val company = fixture.company
val initialCustomerSize = company.customers.size
companyRepository.save(company).block()
val customerToAdd = CustomerReference(id = ObjectId.get(),
keycloakId = "dummy",
username = "customerName",
email = "email",
createdBy = company.employees[0].keycloakId)
//when, then
StepVerifier.create(companyCustomRepositoryImpl.addCustomer(customerToAdd))
.assertNext { updatedCompany -> assertThat(updatedCompany.customers).hasSize(initialCustomerSize + 1) }
.verifyComplete()
}
java.lang.AssertionError:
Expected size:<3> but was:<2> in:
