EPrints::DataObj::User - Class representing a single user.


This class represents a single eprint user record and the metadata associated with it.

EPrints::DataObj::User is a subclass of EPrints::DataObj with the following metadata fields (plus those defined in ArchiveMetadataFieldsConfig:


  • userid (int)
The unique ID number of this user record. Unique within the current repository.
  • rev_number (int)
The revision number of this record. Each time it is changed the revision number is increased. This is not currently used for anything but it may be used for logging later.
  • username (text)
The username of this user. Used for logging into the system. Unique within this repository.
  • password (secret)
The crypted password for this user as generated by EPrints::Utils/crypt. This may be ignored if for example LDAP authentication is being used.
  • usertype (namedset)
The type of this user. The options are configured in metadata-phrases.xml.
  • newemail (email)
Used to store a new but as yet unconfirmed email address.
  • newpassword (secret)
Used to store a new but as yet unconfirmed password.
  • pin (text)
A code required to confirm a new username or password. This code is emailed to the user to confirm they are who they say they are.
  • pinsettime (int)
When the pin code was set, so we can make it time out.
  • joined (time)
The date and time that the user account was created. Before EPrints 2.4 this was a date field so users created before the upgrade will appear to have been created at midnight.
  • email (email)
The email address of this user. Unique within the repository.
  • lang (namedset)
The ID of the prefered language of this user. Only really used in multilingual repositories.
  • editperms (search, multiple)
This field is used to filter what eprints a staff member can approve and modify. If it's unset then they can modify any (given the correct privs. but if it is set then an eprint must match at least one of the searches to be within their scope.
  • frequency (set)
Only relevant to staff accounts. Is the frequency they want to be mailed about eprints matching their scope that are in editorial review. never, daily, weekly or monthly.
  • mailempty (boolean)
Only relevant to staff accounts. If set to true then emails are sent even if there are no items matching the scope.
  • preference (compound)
User preferences which need to be persistent (simple key-value pairs).
