I have the following schema:
TableA:
columns:
id:
type: integer(8)
unsigned: 1
primary: true
autoincrement: true
name:
type: string(255)
notnull: true
group_id:
type: integer(8)
unsigned: 1
notnull: false
default: null
relations:
MyGroup:
local: group_id
foreign: id
type: one
onDelete: CASCADE
MyGroup:
columns:
id:
type: integer(8)
unsigned: 1
primary: true
autoincrement: true
name:
type: string(255)
notnull: true
As you can see, the relation-field group_id is nullable.
The generated filter-form for TableA does not contain a is_empty field
for group_id and therefor it is not possible to filter by TableA-
Objects without a MyGroup.
I could not find a soloution, so I added a custom filter.
Does anyone also believe that an is_empty-filter for nullable
relations should be contained in the generated filter-form?
