[web2py] Adding user to a group after registration

[Chandrakant Kumar]

I'm attempting to add a user to a group , depending on the role he chose
from a dropdown list.

for e.g., In the register form user is presented an option of choosing
user type 1. individual 2. organisation

how do i add the user to the appropriate group depending on his selection?
(i went through the group archives, and one solution was to use
request.args, but i want to use single register link)

You can use an auth.settings.register_onaccept function, which could use auth.add_membership() to add the appropriate membership for the new user.

I didn't even know that existed, but that worked exactly like i wanted,
thanks.

I thought i should post the code, if anybody in future needs it:

#controllers/default.py
def __add_user_membership(form):
group =
db(db.auth_group.role==form.vars.user_type).select().first()
user_id = form.vars.id
auth.add_membership(group.id,user_id)
def user():
auth.settings.register_onaccept = __add_user_membership
# already existing code

[Chandrakant Kumar]

better version :

def __add_user_membership(form):
group_id = auth.id_group(role=form.vars.user_type)
user_id = form.vars.id
auth.add_membership(group.id,user_id)

  )



#adding extra fields required on registration

auth.settings.extra_fields['auth_user']= [
    Field('country', 'reference country'),
    Field('district', 'reference district'),
    Field('account_type', 'reference account_type', label='Account Type')
    ]




default.py
def __add_user_membership(form):

First, please always explain exactly what problem you are having -- what do you expect, and what is happening instead? If you get an error, show the traceback. It can be very difficult to diagnose vague problems like "not having success".
 

default.py
def __add_user_membership(form):
    group_id = auth.id_group(role=form.vars.account_type)

auth.id_group takes the name (not id) of a role stored in the db.auth_group table and returns the id of that role. It appears you are instead passing in the id of a record from your own db.account_type table -- it is not clear what you are expecting to get back.
 

    user_id = form.vars.id
    auth.add_membership(group_id, user_id)

As you are not using the db.auth_group table to assign roles, auth.add_membership will be of no use to you.

Thanks Anthony,

 

 auth.id_group takes the name (not id) of a role stored in the db.auth_group table and returns the id of that role. was so useful.

This worked for me

def add_user_membership(form):

    group_id=form.vars.group_name

    user_id=form.vars.id

    auth.add_membership(group_id,user_id)

    

def user():

    """

     auth.settings.register_onaccept= add_user_membership
