I. Left Tree as Model A, Right Table as Model B

Take Model A as Category and Model B as Category Attributes as an example. Model code example:

java
@Model.model(AriesPlatformCategory.MODEL_MODEL)
@Model(displayName = "Platform Background Category", labelFields = "name")
@Model.Advanced(type = ModelTypeEnum.PROXY)
public class AriesPlatformCategory extends AriesCategory {
    public static final String MODEL_MODEL = "aries.item.AriesPlatformCategory";

    @Field.many2one
    @Field.Relation(relationFields = {"parentCateCode"}, referenceFields = {"code"},store = true)
    @Field(displayName = "Platform Parent Category")
    private AriesPlatformCategory platformCategory;

    @Field.one2many
    @Field(displayName = "Category Attributes")
    @Field.Relation(relationFields = "code", referenceFields = "categoryCode", store = true)
    private List<AriesPlatformCategoryAttr> platformCategoryAttrs;

}
java
@Model.model(AriesPlatformCategoryAttr.MODEL_MODEL)
@Model(displayName = "Aries_Platform Category Attributes", labelFields = "name")
@Model.Advanced(type = ModelTypeEnum.PROXY)
public class AriesPlatformCategoryAttr extends CategoryAttr {
    public static final String MODEL_MODEL = "aries.item.AriesPlatformCategoryAttr";

    @Field.many2one
    @Field(displayName = "Platform Background Category")
    @Field.Relation(relationFields = "categoryCode", referenceFields = "code", store = true)
    private AriesPlatformCategory platformCategory;

}

Before designing the left tree-right table in the designer, the association relationships need to be configured in the model. The following code configures the association between categories and parent categories.

java
@Field.many2one
@Field.Relation(relationFields = {"parentCateCode"}, referenceFields = {"code"},store = true)
@Field(displayName = "Platform Parent Category")
private AriesPlatformCategory platformCategory;

Configure the association between categories and category attributes. One category can have multiple category attributes, a one-to-many (one2many) relationship.

java
@Field.one2many
@Field(displayName = "Category Attributes")
@Field.Relation(relationFields = "code", referenceFields = "categoryCode", store = true)
private List<AriesPlatformCategoryAttr> platformCategoryAttrs;

In the category attribute model, configure the association between attributes and categories. One category attribute belongs to only one category, while one category can have multiple category attributes. Category attributes have a many-to-one (many2one) relationship with categories.

java
@Field.many2one
@Field(displayName = "Platform Background Category")
@Field.Relation(relationFields = "categoryCode", referenceFields = "code", store = true)
private AriesPlatformCategory platformCategory;

Designer examples:

  1. Select Platform Category Attributes as the main model to create a tree-table page Build the association relationship, select Platform Background Category, set the first-level filter condition as empty parent code, and select Platform Category Attributes as the table association relationship field.
  2. Build the association relationship, select Platform Background Category, set the first-level filter condition as empty parent code, and select Platform Category Attributes as the table association relationship field.
  3. Drag and drop the required attribute fields in the table

II. Left Tree as Model A, Right Table also as Model A

Take Model A as Organizational Structure Management for both left and right as an example.

(I) Model Code Example:

java
@Model.model(BasicOrg.MODEL_MODEL)
@Model(displayName = "Organizational Structure Management", summary = "Organizational Structure Management", labelFields = {"orgName"})
@Model.Code(sequence = "ORDERLY_SEQ", prefix = "Org", size = 5, initial = 0)
public class BasicOrg {
    public static final String MODEL_MODEL = "basic.BasicOrg";

    @Field.String
    @Field(displayName = "Name")
    private String orgName;

    @Field.Enum
    @Field(displayName = "Organization Type", summary = "Organization Type")
    private OrgTypeEnum deptType;

    @Field.Enum
    @Field(displayName = "Factory Type", summary = "Visible when organization type is factory")
    private FactoryTypeEnum factoryType;

    @Field.Enum
    @Field(displayName = "Warehouse Type", summary = "Visible when organization type is warehouse")
    private WarehouseTypeEnum warehouseType;

    @Field.String
    @Field(displayName = "Principal", summary = "Principal")
    private String principal;

    @Field.String
    @Field(displayName = "Contact Number", summary = "Contact Number")
    private String phone;

    @Field(displayName = "Parent Organization")
    @Field.many2one
    @Field.Relation(relationFields = {"parentCode"}, referenceFields = {"code"})
    private BasicOrg parent;

    @Field.Text
    @Field(displayName = "Remarks")
    private String remark;

    @Field.Enum
    @Field(displayName = "Data Status", required = true, defaultValue = "ENABLED")
    private DataStatusEnum dataStatus;

    @Field.String
    @Field(displayName = "Parent Organization Code")
    private String parentCode;

    @Field.String(size = 256)
    @Field(displayName = "Tree Code", required = true)
    private String treeCode;

    @Field.one2many
    @Field.Relation(relationFields = "id", referenceFields = "orgId")
    @Field(displayName = "Basic - Affiliated Organization Employees")
    private List<BasicEmployee> basicEmployees;
}

Configure self-association:

java
@Field(displayName = "Parent Organization")
@Field.many2one
@Field.Relation(relationFields = {"parentCode"}, referenceFields = {"code"})
private BasicOrg parent;

(II) Designer Operations:

  1. Select the model Organizational Structure Management, create a page, choose Table as the view type, and select Tree-Table as the layout.

  1. Set the linkage relationship: select Organizational Structure Management as the model; set the first-level filter condition as empty parent code, and select Organizational Structure Management - Parent Organization (field name: parent) as the table association relationship field.
  2. Drag and drop the required attribute fields in the table.
