Does not resolve correct column name with @JoinColumn

Issue Description

if you have a column let’s say “user_id” while using @Column({ name: “user_id” })

and you have other table like photos and you want to reference user_id you get “Error: Referenced column user_id was not found in entity User”

I’m pretty sure it tries to find the column by property name. It should also try finding it by declared value from @Column decorator

Expected Behavior

If it does not fiend property it should look from decorator values…

Actual Behavior

It says:

Error: Referenced column user_id was not found in entity User" even though the column exists

Steps to Reproduce

Create user table like:

@Column({ name: "user_id" })
public userId;

create another table trying to reference it

 @Column({ name: "user_id", type: "uuid", nullable: false })
 public userId: string;

 @JoinColumn({
      { name: "user_id", referencedColumnName: "user_id" },
  })
public user: User

My Environment

Dependency	Version
Operating System	win10
Node.js version	v14.15.0
Typescript version	v4.0.5
TypeORM version	v0.2.31

If you want to create relation you should use relation decorators. You should read docs but basically what you need to do if you want, for instance, one-to-many relation

class User{
@Column({ name: "user_id" })
  public userId;
}

class Photo{
  @Column({ name: "user_id", type: "uuid", nullable: false })
   public userId: string;

  @ManyToOne((type) => User)
  @JoinColumn({
      { name: "user_id", referencedColumnName: "user_id" },
  })
  public user: User
}

Thank you for your reply. This does not function at all for me I found a solution that works.

used “userId” in my referencedColumnName

  @ManyToOne((type) => User)
  @JoinColumn({
      { name: "user_id", referencedColumnName: "userId" },
  })
  public user: User

and in other tables I have

  @Column({ name: "user_id" })
  public userId;

only doing userId works for me. Even though it should also work with column name
