I. Custom Placeholder Definition Expressions

1. Data permission definition expression: ${thisTeacherName}
2. Query condition definition in the interface designer: $#{thisTeacherName} (needs to add a # symbol) The above configurations can be checked by viewing the originRsql in the queryWrapper to see if the placeholders are correctly replaced.

II. Visibility and Filter Condition Expression Definitions

Visibility and filtering can both be defined in field annotations and xml definitions.

1. Visibility: invisible="$!{activeRecord.deadline}" / invisible = true

    @Field.String
    @Field(displayName = "View/Page", invisible = true)
    private String viewName;

2. Filtering: domain = " code == ${activeRecord.id} " / domain = "code == '111' "

    @Field.one2many
    @Field(displayName = "Child Order List", summary = "Child Order List")
    @Field.Relation(relationFields = {"code"}, referenceFields = {"code"}, domain = "code != '1234'")
    private List<ChildOrder> orderList;
