    Represents a survey entity in the database.

    is the entity's name in database.

    This class defines the structure of the survey entity in database:

    • id: unique identifier for the survey.
    • title: title of the survey (must be unique).
    • description: detailed information or context about the survey.
    • status: the current state of the survey (draft, publish, archive, censored), defaults to draft.
    • public: defines whether the survey is accessible publicly or only to selected users.
    • user: the creator of the survey (relation to the User entity).
    • category: the category to which the survey belongs (relation to the Category entity).
    • createdAt: timestamp of when the survey was created.
    • updatedAt: timestamp of when the survey was last updated.
    // Create a new survey
    const survey = new Survey()
    survey.title = "Customer Satisfaction"
    survey.description = "Survey about customer experience"
    survey.status = "draft"
    survey.public = true
    survey.user = userInstance
    survey.category = categoryInstance
    await survey.save()

    Decorators used:

    • @Entity(): Declares the class as a database entity.
    • @PrimaryGeneratedColumn(): Marks the primary key column with auto-increment.
    • @Column(): Maps a class property to a database column.
    • @ManyToOne(): Defines a many-to-one relationship between entities.
    • @OneToMany(): Defines a one-to-many relationship between entities.
    • @Field(): Exposes a class property to the GraphQL schema.
