Here's a multi-recipient email function I just got working. It is
newbie-created and horrible, but I'm hoping that building something like
this is such a common requirement that someone might be willing to give
tips that others could benefit from.
Can anyone give guidance on any part of it?
*Model*
Parent: fields generally include senderID, subject-line, body-of-message
Child: fields generally include recipientID (can be many children for one
parent)
*Function*
The hard part is selecting more than one recipient.
First possible error that needs correcting: Used 'selectable' from grid. Is
this a bad idea?
grid = SQLFORM.grid(potentialEmailRecipientsQuery, selectable=lambda ids:
redirect(URL('message_send_to', vars=dict(ids=ids)), searchable=False,
sortable=False, editable=False,create=False, deletable=False, details=False
, fields=[db.auth_user.id, db.auth_user.first_name, db.auth_user.last_name,
db.auth_user.currentPosition])
Two problems with this (1) if allow searching or sorting for recipients, it
UN-selects previously selected recipients (2) Don't know how to select
recipients and type the subject-line/body of message on same page. In this
example, user picks recipients on one page, then gets sent to new page to
type subject/body: message_send_to function. Looks unpolished.
Finally, in the 2nd function, capturing the recipient group method seems
like it's done wrong. Look at the code below. If there is only one
recipient, the object list is empty and I have to write special code for
just one recipient. Did I do something wrong in capturing recipient list?
emailRecipients =
db(db.auth_user.id.belongs(request.get_vars.ids)).select()
def message_send_to():
emailRecipients =
db(db.auth_user.id.belongs(request.get_vars.ids)).select()
form=SQLFORM.factory(db.InternalMessage)
if form.process().accepted:
messageID =
db.InternalMessage.insert(**db.InternalMessage._filter_fields(form.vars))
form.vars.messageID=messageID
if len(request.get_vars.ids) == 1: ## why need this if there is
only one recipient? See "for" loop below.
db.InternalMessageRecipient.recipientOfMessage.default =
request.get_vars.ids
internalMessageRecipientMessageID =
db.InternalMessageRecipient.insert(**db.InternalMessageRecipient._filter_fields(form.vars))
if len(request.get_vars.ids) > 1: ## works great ONLY if there is
more than one recipient. If only 1 recipient, it is empty!
for row in emailRecipients:
db.InternalMessageRecipient.insert(recipientOfMessage=row.auth_user.id,
messageID=messageID)
session.flash='Your message has been sent.'
redirect(URL('view_user_profile', args=[auth.user_id]))
return locals()
If anyone can give some pointers or has their own
pick-several-email-recipients example, that would be great.
thanks,
Alex Glaros
