I have a user entinty that looks as follows:
#ObjectType()
#Entity()
export class User extends BaseEntity {
#Field(() => String)
#ObjectIdColumn()
_id: ObjectID;
#Field(() => String)
#Column({ type: "varchar", unique: true, length: 25 })
username: string;
// Profile
#Field(() => Profile, { nullable: true })
#OneToOne(() => Profile, {eager: false})
#JoinColumn()
profile: Profile;
}
My profile entity looks as follows:
#ObjectType()
#Entity()
export class Profile extends BaseEntity {
#Field(() => String)
#ObjectIdColumn()
_id: ObjectID;
#Field(() => String, { nullable: false })
#Column({ nullable: false })
email: string;
#Field(() => String, { nullable: false })
#Column({ nullable: false })
username: string;
}
If i query the user as follows:
User.findOne({
where: { email },
relations: ["profile"],
});
The profile is null on the console logs and i have a profile a user who has a profile in my mongodb doccuments. What may be possibly the problem with my code?

I am creating a nestjs project with typeorm and postgresql. Here I am creating a user entity.
My entity will be like
{
email: string,
name: string,
avatar: {
public_key: string;
url: string;
}
}
In avatar column I need to add a object with public_key and url.
I create two entity like this-
#Entity()
class Avatar {
#Column({ type: "text", nullable: true })
public_key: string;
#Column({ type: "text", nullable: true })
url: string;
}
#Entity()
#Tree("closure-table")
export class User {
#PrimaryGeneratedColumn()
id: number;
#Column({ type: "text", nullable: false })
userName: string;
#Column({ type: "text", nullable: false })
email: string;
#Column({ type: "text", nullable: false })
firstName: string;
#Column({ type: "text", nullable: false })
lastName: string;
#Column({ type: "text", nullable: false, select: false })
password: string;
#Column({ type: "text", nullable: true })
socket_id: string;
#Column({ type: "text", nullable: true, select: false })
otp: string;
#TreeChildren()
avatar: Avatar;
#Column({ type: "boolean", default: false, nullable: false })
is_verify: boolean;
#CreateDateColumn()
created_at: Date;
#UpdateDateColumn()
updated_at: Date;
//Before Insert Injection
#BeforeInsert()
createUserName() {
this.userName = uniqid.time()
}
}
Here I use closure-table to do nested avatar entity
Here I write
#TreeChildren()
avatar: Avatar;
For nesting Avatar Entity
Then in my controller I try to create my first data-
const result = await this.userRepository.create({
...userInput,
otp: secret.base32,
password: passwordHash,
});
await this.userRepository.save(result)
Note: avatar field is not required. Avatar field will be add when user update their profile. Here I only create first user data.
But I am getting this error-
Cannot read properties of undefined (reading 'getEntityValue')
Additionally, here is my userInput
#InputType()
export class UserInput {
#Field(() => String, { nullable: false })
#IsString()
#IsEmail()
#IsNotEmpty()
email: string;
#Field(() => String, { nullable: false })
#IsString()
#IsNotEmpty()
firstName: string;
#Field(() => String, { nullable: false })
#IsString()
#IsNotEmpty()
lastName: string;
#Field(() => String, { nullable: false })
#IsString()
#MinLength(8)
#MaxLength(20)
#IsNotEmpty()
#Matches(/^.*(?=.{4,10})(?=.*\d)(?=.*[a-zA-Z]).*$/, { message: "password too weak" })
password: string
}
Please help me. I need this is very much. Over 10 days, I can't solve this. Please help me.
I have a user schema:
#ObjectType()
export class User {
#Field(() => String)
_id: string;
#Field(() => String)
#prop({ required: true })
userName: string;
#Field(() => UserType)
#prop({ enum: UserType })
userType: UserType;
#Field(() => String)
#prop({ required: true })
email: string;
#prop({ required: true })
password: string;
#Field(() => Employee)
#prop({ required: false })
employee: Employee;
#Field(() => Employer)
#prop({ required: false })
employer: Employer;
}
and the employee field has this schema:
#ObjectType()
class Employee {
#Field(() => String)
firstName: string;
#Field(() => String)
middleName: string;
#Field(() => String)
lastName: string;
#Field(() => String)
birthday: string;
#Field(() => String)
address1: string;
#Field(() => String)
address2: string;
#Field(() => String)
phoneNumber: string;
#Field(() => String)
emailAddress: string;
#Field(() => String)
socialMedia: string;
#Field(() => String)
imageLink: string;
#Field(() => [WorkExperiences])
workExperiences: WorkExperiences[];
#Field(() => Personality)
personality: Personality;
#Field(() => Direction)
direction: Direction;
#Field(() => [Education])
education: Education[];
#Field(() => [Certificates])
certificates: Certificates[];
#Field(() => [Awards])
awards: Awards[];
#Field(() => String)
applications: string;
}
I want to create a login form which only adds email and username then redirect to a onboarding page.
I am trying to create a separate mutations with Education, workExperience and other stuffs.
But I am not sure what I am doing.
What I did so far was to create a resolver for example education:
#Authorized()
#Mutation(() => User)
createEducation(
#Arg("input") input: CreateEducationInput,
#Ctx() context: Context
) {
const user = context.user!;
return this.qualificationService.createEducation({
...input,
user: user?._id,
});
}
But I can't seem to create education and throws some error.
I am not sure if I am doing this correctly. Really need help. Thanks guys!
There are 3 tables: users, posts, likes, (roles - but it works fine). One user has multiple posts and multiples likes. One post has multiple likes. As I understand, connections are
User #HasMany(() => Post) and #HasMany(() => Like)
Post #HasMany(() => Like)
Problem: In my user.service.ts when I run this function
const user = await this.userRepository.findOne({ where: { email }, include: { all: true } })
return user
it gets Error:
likes.userId column does not exist
Code:
Users ->
#Table({ tableName: 'users' })
export class User extends Model<User> {
#Column({ type: DataType.INTEGER, unique: true, autoIncrement: true, primaryKey: true })
id: number;
#Column({ type: DataType.STRING, unique: true, allowNull: false })
email: string;
#Column({ type: DataType.STRING, allowNull: false })
password: string;
#BelongsToMany(() => Role, () => UserRoles)
roles: Role[]
#HasMany(() => Post)
posts: Post[]
#HasMany(() => Like)
likes: Like[]
Posts ->
#Table({ tableName: 'posts' })
export class Post extends Model<Post> {
#Column({ type: DataType.INTEGER, unique: true, autoIncrement: true, primaryKey: true })
id: number;
#Column({ type: DataType.STRING, allowNull: false })
title: string;
#Column({ type: DataType.STRING, allowNull: false })
content: string;

#Column({ type: DataType.INTEGER })
userId: number;
#BelongsTo(() => User)
author: User;
#HasMany(() => Like)
likes: Like[]
Likes ->
#Table({ tableName: 'likes' })
export class Like extends Model<Like> {
#Column({ type: DataType.INTEGER, unique: true, autoIncrement: true, primaryKey: true })
id: number;
#ForeignKey(() => Post)
#Column({ type: DataType.INTEGER })
postId: number;
#BelongsTo(() => Post)
post: Post
#ForeignKey(() => User)
#Column({ type: DataType.INTEGER })
userId: number;
#BelongsTo(() => User)

What am I missing?
That was my mistake. When you editing columns, you manually need to delete some related tables in order to see the changes. Yes, simple as that.
I have an app where an user can create a list of Recipes and each Recipe can have multiple comments that many users can post.
This is what im trying to do:
I have a comments Enitity:
import {
Entity,
PrimaryGeneratedColumn,
Column,
BeforeUpdate,
ManyToOne,
JoinColumn,
ManyToMany,
} from 'typeorm';
import { UserEntity } from 'src/user/models/user.entity';
import { RecipeEntity } from 'src/recipe/model/recipe-entry.entity';
import { User } from 'src/user/models/user.interface';
#Entity('comments_entry')
export class CommentsEntity {
#PrimaryGeneratedColumn()
id: number;
#Column({ type: 'timestamp', default: () => 'CURRENT_TIMESTAMP' })
createdAt: Date;
#Column({ type: 'timestamp', default: () => 'CURRENT_TIMESTAMP' })
updatedAt: Date;
#BeforeUpdate()
updateTimestamp() {
this.updatedAt = new Date();
}
#ManyToOne(
type => UserEntity,
user => user.username,
)
author: UserEntity;
#Column()
recipe_id: number;
#Column()
author_id: number;
#ManyToOne(
type => RecipeEntity,
recipe => recipe.comment,

#JoinColumn({ name: 'recipe_id', referencedColumnName: 'id' })
comment: RecipeEntity;
}

As an user i can post recipes. But im failing to add comments on specific recipes.
2 errors:
When i create a Recipe with some hardcoded comments, the users and recipe table gets filled but the comments_entry table is empty.
And im failing to implement the method to add comments to a specific recipe.
Controller:
#UseGuards(JwtAuthGuard)
#Post('recipe/:id')
createComment(
#Param() params,
#Body() comment: string,
#Request() req,
): Observable<RecipeEntry> {
const user = req.user;
const id = params.id;
return this.recipeService.createComment(user, id, comment);
}
createComment(id: number, commentEntry: string): Observable<RecipeEntry> {
return from(this.findOne(id)).pipe(
switchMap((recipe: RecipeEntry) => {
const newComment = recipe.comment.push(commentEntry);
return this.recipeRepository.save(newComment);
}),
);
}
Type 'Observable<DeepPartial[]>' is not assignable to type 'Observable'.
Property 'comment' is missing in type 'DeepPartial[]' but required in type 'RecipeEntry'.ts(2322)
recipe-entry.interface.ts(18, 3): 'comment' is declared here.
Any help?
Can't build working example but may be would helpful:
Redo your relations (I simplified entities for example, but you should use full:) ):
#Entity('comments_entry')
export class CommentsEntity {
#Column()
authorId: number;
#ManyToOne(type => UserEntity, user => user.id)
author: UserEntity;
#ManyToOne(type => RecipeEntity, recipe => recipe.id)
recipe: RecipeEntity;
}
#Entity('recipe_entry')
export class RecipeEntity {
#Column()
authorId: number;
#ManyToOne(type => UserEntity, user => user.id)
author: UserEntity;
#OneToMany(type => CommentsEntity, comment => comment.recipe)
comments: CommentsEntity[];
}
#Entity('user_entry')
export class UserEntity {
#OneToMany( type => RecipeEntity, recipe => recipe.author)
recipes: RecipeEntity[];
#OneToMany(type => CommentsEntity, comment => comment.author)
comments: CommentsEntity[];
}
RecipeDto something like:
RecipeDto: {
authorId: number | string,
comments: CommentDto[],
****other recipe data
}
create new Recipe:
createRecipe(recipeDto: RecipeDto): Observable<RecipeEntry> {
const { comments, authorId } = recipeDto;
if(comments) {
const commentPromises = comments.map(async comment => {
comment.authorId = authorId;
return await this.commentRepository.save(comment);
});
recipeDto.comments = await Promise.all(commentPromises);
}
return await this.recipeRepository.save(recipeDto);
}
If I understood correctly, you are trying that:
One User --> Many Recipes
One User --> Many Comments
One Recipe --> Many Comments
Your entities seems right.
Normally a typeorm repository returns a promise and not an observable.
You need to convert it to an Observable.
And at the moment you are trying to store a comment in the recipeRepo. You should save the whole recipe. And before you have to save the comment in the comment repo (if you are not working with cascades).
Something like this:
createComment(id: number, commentEntry: string): Observable<RecipeEntry> {
return from(this.findOne(id)).pipe(
switchMap((recipe: RecipeEntry) => {
return from(this.commentRepository.save(newComment)).pipe(
map(com: Comment) => {
recipe.comment.push(com);
return from(this.recipeRepository.save(recipe));
}
)
);
}
If you enable cascades, you can do this in only one call.
I'm new to typeorm, maybe someone can resolve my problem.
I'm using NestJS and TypeORM and have two tables (categories and talents). I wish to find a solution to limit typeorm join queries.
each category can have many talents in talent_worked and each talent can have many categories in working_categories.
i like to find all categories and there respected talent but i wish to get(limit) only five talents.
Talent:
#Entity('talents')
#Unique(['mobile'])
export class TalentsEntity extends BaseEntity {
#PrimaryGeneratedColumn('uuid')
id: string;
#Column({ nullable: true })
name: string;
#Column({ unique: true })
mobile: string;
#Column({ nullable: true })
email: string;
#Column({ select: false })
password: string;
#Column({ select: false })
salt: string;
#Column({ default: false })
isBlocked: boolean;
#Column({ default: true })
isActive: boolean;
// relation to categories model
#ManyToMany(
type => CategoriesEntity,
categoriesEntity => categoriesEntity.talent_worked,
{ eager: true },
)
#JoinTable({ name: 'talents_working_categories' })
working_categories: CategoriesEntity[];
}
Category:
#Entity('categories')
#Unique(['title'])
export class CategoriesEntity extends BaseEntity {
#PrimaryGeneratedColumn('uuid')
id: string;
#Column({ nullable: true })
title: string;
// relation to talents
#ManyToMany(
type => TalentsEntity,
talentsEntity => talentsEntity.working_categories,
{ eager: false },
)
talent_worked: TalentsEntity[];
}
here is my typeorm query so far:
const query = await this.createQueryBuilder('category');
query.leftJoinAndSelect('category.talent_worked', 'talent');
query.leftJoinAndSelect('talent.working_categories', 'talentCategories');
query.where('talent.isActive = :isActive AND talent.isBlocked = :isBlocked', { isActive: true, isBlocked: false});
if (categoryId) query.andWhere('category.id = :categoryId', { categoryId });
query.select([
'category.id',
'category.title',
'talent.id',
'talent.name',
'talentCategories.id',
'talentCategories.title',
]);
query.orderBy('category.created_at', 'ASC');
query.addOrderBy('talent.created_at', 'ASC');
return await query.getMany();
