Summary of Operations

1. Creating an Account and User:

• A new Account and User are created.
• The user's email is set to '[email protected]'.
• The user is added to the account.
• The account (with the user) is persisted and flushed to the database.

2. Creating a Project and Assigning a User:

• A new Project is created with the name 'My First Project'.
• The previously created user is fetched using their email.
• The association (AccountUser) between the user and account is fetched.
• If the AccountUser is found, the project is assigned to this AccountUser.
• The project is persisted and flushed to the database.

3. Creating Documents and Assigning Them:

• The ORM's entity manager is cleared to simulate a new request.
• Two new Document objects are created and associated with the previously created account.
• The project named 'My First Project' is fetched.
• The user is refetched using their email.
• The association (AccountUser) is refetched, and specific relations (assignedProjects, assignedDocuments) are populated.
• Note: Populating these relations causes a blow-up due to a broken relation issue.
• Once flushed, there is an attempt to create a new account user with an undefined user.

Entity Relationships

AccountUser

• ManyToOne: account (Account) - Represents the many-to-one relationship with Account.
• ManyToOne: user (User) - Represents the many-to-one relationship with User, with cascade updates.
• OneToMany: assignedDocuments (Document) - Represents the one-to-many relationship with Document, where the Document entity refers to this AccountUser as assignee.
• ManyToMany: assignedProjects (Project) - Represents the many-to-many relationship with Project.

Account

• PrimaryKey: id - A unique identifier for the account.
• ManyToMany: users (User) - Represents the many-to-many relationship with User, using AccountUser as the pivot entity.
• OneToMany: projects (Project) - Represents the one-to-many relationship with Project.

Document

• PrimaryKey: id - A unique identifier for the document.
• ManyToOne: project (Project) - Represents the many-to-one relationship with Project.
• ManyToOne: account (Account) - Represents the many-to-one relationship with Account.
• ManyToOne: assignee (AccountUser) - Represents the many-to-one relationship with AccountUser, indicating the document's assignee.

Project

• PrimaryKey: id - A unique identifier for the project.
• Property: name - The name of the project.
• ManyToOne: account (Account) - Represents the many-to-one relationship with Account.
• OneToMany: documents (Document) - Represents the one-to-many relationship with Document, where the Document entity refers to this Project.
• ManyToMany: assignedUsers (AccountUser) - Represents the many-to-many relationship with AccountUser, indicating users assigned to the project.

User

• PrimaryKey: id - A unique identifier for the user.
• Property: email - The unique email address of the user.
• ManyToMany: accounts (Account) - Represents the many-to-many relationship with Account, mapped by the users property in Account.

Relationship Summary

• Account and User have a many-to-many relationship through the AccountUser pivot entity.
• AccountUser has a one-to-many relationship with Document as the assignee and a many-to-many relationship with Project.
• Account has a one-to-many relationship with Project.
• Project has a one-to-many relationship with Document and a many-to-many relationship with AccountUser.
• Document has many-to-one relationships with Project, Account, and AccountUser as the assignee.
