Apollo GraphQl model attribute is not accessing object in ReactJs - reactjs

Question

I am implementing category and subcategory display in ReactJs using Apollo GraphQl Query.
I tried to using same table as category with fields.
id,
category_name,
category_img,
category_parent_id ( id from same table),
category_status,
typeDefs and resolver are belows
Category.js
const typeDefs = gql`
extend type Query {
getSingleCategory(id: ID): allCategory
}
`;
type allCategory {
id: ID!
category_name: String
category_img: String
category_parent_id: Int
category_status: Status
}
const resolvers = {
Query: {
getSingleCategory: async (parent, args, context, info) => {
var data = await db.category.findOne({
where: {
id: args.id,
},
include: [
{
model: db.category,
as: "children",
attributes: [["category_name", "children_name"]],
nested: true,
required: false,
},
],
required: false,
});
return data;
},
},
},
Model in GraphQl
module.exports = function (sequelize, DataTypes) {
var category = sequelize.define(
"category",
{
id: {
type: DataTypes.INTEGER(10).UNSIGNED,
allowNull: false,
primaryKey: true,
autoIncrement: true,
},
category_name: {
type: DataTypes.STRING(256),
allowNull: false,
},
category_img: {
type: DataTypes.STRING(256),
allowNull: false,
},
category_parent_id: {
type: DataTypes.INTEGER(10).UNSIGNED,
allowNull: false,
references: {
// WorkingDays hasMany Users n:n
model: "category",
key: "children",
},
},
category_status: {
type: DataTypes.ENUM("Acitve", "Inactive"),
allowNull: false,
},
},
{
tableName: "category",
timestamps: false,
}
);
category.associate = function (models) {
models.category.belongsTo(models.category, {
onDelete: "CASCADE",
foreignKey: "category_parent_id",
as: "children",
targetKey: "id",
});
};
return category;
};
In ReactJs
category.ts
export const GET_CATEGORYBY_ID = gql`
query($catId: ID!) {
getSingleCategory(id: $catId) {
id
category_name
category_img
category_parent_id
category_status
}
}
`;
I am trying to accessing {data.getSingleCategory} , I got all parameters but not able to get children_name from same table as parent_name.
Anyone can tell me what is the issue I am not able to access that children_name as attribute from same table Or there any other way so that we can access category/subcategory from same table and display it to reactjs template.

Answer 1

Not defined [separately] in types, not used/defined [as 'children' property?] in parent type, not requested in query ... simply filtered out from response.
