May 25, 2018 - The default way is to access User directly, which is the built-in Django model that provides us with username, email, password, firstname. Execute the Select query and process the result set returned by the SELECT query in Python to retrieve rows from MySQL table. Use Python variables in the Select query to pass dynamic values to query. Use fetchall, fetchmany and fetchone methods of a cursor class to fetch limited rows from a table. Count total rows of a table.

Usernames and UnicodeDjango originally accepted only ASCII letters and numbers inusernames. Although it wasn’t a deliberate choice, Unicodecharacters have always been accepted when using Python 3. Django1.10 officially added Unicode support in usernames, keeping theASCII-only behavior on Python 2. FirstnameOptional. 30characters or fewer. LastnameOptional.

150characters or fewer. EmailOptional. A hash of, and metadata about, the password.

(Django doesn’tstore the raw password.) Raw passwords can be arbitrarily long and cancontain any character. GroupsMany-to-many relationship to userpermissionsMany-to-many relationship to isstaffBoolean.

Designates whether this user can access the admin site. Designates whether this user account should be consideredactive.

We recommend that you set this flag to False instead ofdeleting accounts; that way, if your applications have any foreign keysto users, the foreign keys won’t break.This doesn’t necessarily control whether or not the user can log in.Authentication backends aren’t required to check for the isactiveflag but the default backend and thedo. You canuseorif you want to allow inactive users to login. In this case, you’ll alsowant to customize theused by theas it rejects inactiveusers.

Be aware that the permission-checking methods such asand theauthentication in the Django admin all return False for inactiveusers. Designates that this user has all permissions withoutexplicitly assigning them. LastloginA datetime of the user’s last login. DatejoinedA datetime designating when the account was created. Is set to thecurrent date/time by default when the account is created. Attributes class models. User isauthenticatedRead-only attribute which is always True (as opposed toAnonymousUser.isauthenticated which is always False).

This isa way to tell if the user has been authenticated. This does not implyany permissions and doesn’t check if the user is active or has a validsession.

Even though normally you will check this attribute onrequest.user to find out whether it has been populated by the(representing the currently logged-in user), you should know thisattribute is True for any instance. IsanonymousRead-only attribute which is always False. This is a way ofdifferentiating andobjects. Generally, you should prefer usingto thisattribute. Methods class models. User getusernameReturns the username for the user.

Since the User model can beswapped out, you should use this method instead of referencing theusername attribute directly. GetfullnameReturns the plusthe, with a space inbetween.

GetshortnameReturns the. Setpassword( rawpassword)Sets the user’s password to the given raw string, taking care of thepassword hashing. Doesn’t save theobject.When the rawpassword is None, the password will be set to anunusable password, as ifwere used. Checkpassword( rawpassword)Returns True if the given raw string is the correct password forthe user. (This takes care of the password hashing in making thecomparison.) setunusablepasswordMarks the user as having no password set. This isn’t the same ashaving a blank string for a password.for this userwill never return True.

Doesn’t save theobject.You may need this if authentication for your application takes placeagainst an existing external source such as an LDAP directory. HasusablepasswordReturns False ifhasbeen called for this user.

Changed in Django 2.1:In older versions, this also returns False if the password isNone or an empty string, or if the password uses a hasherthat’s not in the setting. Thatbehavior is considered a bug as it prevents users with suchpasswords from requesting a password reset. Getgrouppermissions( obj=None)Returns a set of permission strings that the user has, through theirgroups.If obj is passed in, only returns the group permissions forthis specific object. Getallpermissions( obj=None)Returns a set of permission strings that the user has, both throughgroup and user permissions.If obj is passed in, only returns the permissions for thisspecific object.

Hasperm( perm, obj=None)Returns True if the user has the specified permission, where permis in the format '.' (seedocumentation on ). If the user isinactive, this method will always return False.If obj is passed in, this method won’t check for a permission forthe model, but for this specific object. Hasperms( permlist, obj=None)Returns True if the user has each of the specified permissions,where each perm is in the format'.' If the user is inactive,this method will always return False.If obj is passed in, this method won’t check for permissions forthe model, but for the specific object.

Hasmoduleperms( packagename)Returns True if the user has any permissions in the given package(the Django app label). If the user is inactive, this method willalways return False. Emailuser( subject, message, fromemail=None,.kwargs)Sends an email to the user. If fromemail is None, Django usesthe. Any.kwargs are passed to theunderlying call. Manager methods class models. UserManagerThe model has a custom managerthat has the following helper methods (in addition to the methods providedby ): createuser( username, email=None, password=None,.extrafields)Creates, saves and returns a.The andare set as given.

Thedomain portion of isautomatically converted to lowercase, and the returnedobject will haveset to True.If no password is provided,willbe called.The extrafields keyword arguments are passed through to the’s init method toallow setting arbitrary fields on a.See for example usage. Createsuperuser( username, email, password,.extrafields)Same as, but sets andto True. Login and logout signalsThe auth framework uses the following thatcan be used for notification when a user logs in or out.

UserloggedinSent when a user logs in successfully.Arguments sent with this signal: sender The class of the user that just logged in. Request The current instance. User The user instance that just logged in. UserloggedoutSent when the logout method is called. Sender As above: the class of the user that just logged out or Noneif the user was not authenticated. Request The current instance. User The user instance that just logged out or None if theuser was not authenticated.

UserloginfailedSent when the user failed to login successfully sender The name of the module used for authentication. Credentials A dictionary of keyword arguments containing the user credentials that werepassed to or your own customauthentication backend. Credentials matching a set of ‘sensitive’ patterns,(including password) will not be sent in the clear as part of the signal. Request The object, if one was provided to. Available authentication backendsThe following backends are available in: class ModelBackendThis is the default authentication backend used by Django. Itauthenticates using credentials consisting of a user identifier andpassword. For Django’s default user model, the user identifier is theusername, for custom user models it is the field specified byUSERNAMEFIELD (see ).It also handles the default permissions model as defined forand.,and allow an object to be passed as aparameter for object-specific permissions, but this backend does notimplement them other than returning an empty set of permissions ifobj is not None.

Authenticate( request, username=None, password=None,.kwargs)Tries to authenticate username with password by calling. If no usernameis provided, it tries to fetch a username from kwargs using thekey. Returns anauthenticated user or None.request is an and may be Noneif it wasn’t provided to(which passes it on to the backend). Getuserpermissions( userobj, obj=None)Returns the set of permission strings the userobj has from theirown user permissions.

Returns an empty set iforis False. Getgrouppermissions( userobj, obj=None)Returns the set of permission strings the userobj has from thepermissions of the groups they belong. Returns an empty set iforis False. Getallpermissions( userobj, obj=None)Returns the set of permission strings the userobj has, including bothuser permissions and group permissions. Returns an empty set iforis False.

Hasperm( userobj, perm, obj=None)Uses to check if userobj has thepermission string perm. Returns False if the user is not. Hasmoduleperms( userobj, applabel)Returns whether the userobj has any permissions on the appapplabel. UsercanauthenticateReturns whether the user is allowed to authenticate. To match thebehavior ofwhich,this method returns False for users with.

Custom user models thatdon’t have anfield are allowed. Class AllowAllUsersModelBackendSame as except that it doesn’t reject inactive usersbecause always returns True.When using this backend, you’ll likely want to customize theused by theby overriding themethod as it rejects inactive users. Class RemoteUserBackendUse this backend to take advantage of external-to-Django-handledauthentication. It authenticates using usernames passed in. Seethedocumentation.If you need more control, you can create your own authentication backendthat inherits from this class and override these attributes or methods: createunknownuserTrue or False. Determines whether or not a user object iscreated if not already in the database Defaults to True.

Authenticate( request, remoteuser)The username passed as remoteuser is considered trusted. Nexusmods dark souls remastered. Thismethod simply returns the user object with the given username, creatinga new user object if isTrue.Returns None if isFalse and a User object with the given username is not found inthe database.request is an and may be Noneif it wasn’t provided to(which passes it on to the backend). Cleanusername( username)Performs any cleaning on the username (e.g. Stripping LDAP DNinformation) prior to using it to get or create a user object. Returnsthe cleaned username. Configureuser( request, user)Configures a newly created user.

This method is called immediatelyafter a new user is created, and can be used to perform custom setupactions, such as setting the user’s groups based on attributes in anLDAP directory. Returns the user object.request is an and may be Noneif it wasn’t provided to(which passes it on to the backend).

Utility functions getuser( request)Returns the user model instance associated with the given request’ssession.It checks if the authentication backend stored in the session is present in. If so, it uses the backend’sgetuser method to retrieve the user model instance and then verifiesthe session by calling the user model’smethod.Returns an instance ofif the authentication backend stored in the session is no longer in, if a user isn’t returned by thebackend’s getuser method, or if the session auth hash doesn’tvalidate.Contents.Browse.
