sciros opened a new issue, #14637:
URL: https://github.com/apache/grails-core/issues/14637
I am experiencing a recurring issue regarding one-to-many mappings and the
generated schema.
Using Grails 3.1.8 and grails-datastore-\* 5.0.8.
The code is basically as follows:
```
class Feature implements GormEntity<Feature> {
String name
String uri
Set scenarios = []
Run run
static belongsTo = [run: Run]
static hasMany = [scenarios: Scenario]
}
class Scenario implements GormEntity<Scenario> {
Date created
String keyword
String name
String uri
Set<Step> steps = []
Set<Hook> hooks = []
Background background
Feature feature
static belongsTo = [feature: Feature]
static hasMany = [steps: Step, hooks: Hook] //includes background steps
...
}
class Hook implements GormEntity<Hook> {
String error
HookType hookType
Scenario scenario
static belongsTo = [scenario: Scenario]
static constraints = {
error nullable: true
}
}
```
(There is also a Run and a Step class but they are straightforward and
exactly what you'd expect from looking at the ones above.) Anyway, I feel like
I've already added a kind of redundancy in the code by explicitly specifying
fields for some of the mappings as well as types. Nevertheless, after executing
a Grails integration test run (or dev startup) I occasionally get the following
error:
```
Caused by: org.hibernate.MappingException: Missing type or column for
column[hooks_hook] on domain[com.sciros.cucumber.reporting.types.Scenario]

```
If I perform a `grails clean` then things are OK for a couple of test runs.
Eventually I run into this error again. Having spent time away from coding in
Grails and GORM for a while, I am not sure this is an actual "issue" to submit
as opposed to a coding error on my part. That said, I see nothing that
indicates an error and the code appears to work "some" of the time (integration
tests running queries that require proper mapping pass).
