= !BluePrint for Messaging (Old) = == Inbound Messages == * When a message is picked up by the handler, it decides whether it's an XForm or not. * If it is, then it is routed direct to the relevant resource. * If not then it is added to the Master Message Log ({{{msg_log}}}) * When new messages arrive in the Master Message Log, then the Parser looks for keywords & tries to Route automatically - either to a resource or to a {{{pe_pentity}}} (NB 'routing' to a resource is actually just 'tagging'). == Routing within Eden == * Users can view the Master Message Log via the 'Ticketing Module' UI & do manual Routing - either to a resource or a {{{pe_pentity}}}. * Users can Subscribe to Resources in order to receive copies of all messages which are routed to a resource. * This is done by pressing the 'Subscribe' button on the page for that Resource. * Button becomes 'Unsubscribe' if user already subscribed. * When a user visits a Resource via it's Web UI, then the [wiki:RESTController] scans the {{{msg_log}}} & provides access to associated messages in the views (display/update views have a list of associated messages in a table below the main record. list views have an extra column showing the number of messages tagged to this resource & number unread by this user ({{{unread(read)}}}) which is hyperlinked to a view which displays these records. == Outbound Messages == * If a pentity has a message sent to them (they subscribed or routed to them automatically or manually) then as well as being tagged for them, a copy is placed in the Outbox with them as recipient. Their list of Contacts is browsed & the appropriate contact method is used, depending on the priority of the message (e..g. a user may want to be sent an SMS for a high priority message, such as a security alert, but just be sent an email if it's just an update to one of their projects). If there are multiple methods available for a priority level then all methods are used at once - each having a separate entry in the outbox. * XML exports (such as RSS feeds) include tagged messages as linked resources: * S3ResourceController has a hook for a function that retrieves all message URLs for a resource: s3xrc = s3xrc.S3ResourceController(..., messaging=) * This function takes the the resource name (=full tablename incl. prefix) and the record ID as arguments, and returns a list of URLs to messages for this resource and user, where each list item is (url, timestamp), with timestamp refering to the message timestamp * The XML exporter inserts one element per message and resource element as child of the tag * This can be used for any feeds that are produced of the XML exporter * Requires: ~~make RSS feeds an XML export template~~ * From address for emails can be set by changing mail.settings.sender under the hood. * If using gmail as Server for Outbound Email messages then this will override mail.settings.sender, so need to integrate this * Grey out the setting & explain why in Help if this option is set * Allow a per-user Outbound server override * Could use !GoogleVoice for Outbound SMS: http://code.google.com/p/pygooglevoice/ == Message Flows == [[Image(Message Flows.png)]] == How do we achieve this? == * Table {{{msg_log}}} is used as a replacement for the current {{{msg_inbox}}} & {{{ticket_log}}}. * Fields: sender, subject, body, verified, actionable, assignee (multiple?), actioned, priority * Q: Do we move some of these 'ticketing' fields to a separate, linked {{{ticket_msg}}} table? * Table {{{msg_tag}}} is used to tag messages for resources. * Fields: message_id, resource, record (uid) * Q: How to display this nicely? * A: Give the message a tab with all distribution resources (db.tables). Once a table is selected, a second selector with all UUIDs (represented, of course) in that table appears, so you can choose the target. Use s3xrc.model.configure to add a name_nice for each table. * Table {{{pe_subscription}}} is used to maintain subscriptions for a {{{pe_pentity}}}. * Fields: pr_pe_id, resource, record (uid) * Subscriptions can be added/deleted from the linked resource * Add to Views (layout.html) * http://myserver.org/eden/msg/subscribe?resource=org_org&uid=XXX * Controller needs writing * Subscriptions can be viewed from the user's subscriptions page * ~~Add to 01_menu.py & pr.py~~ * Table {{{msg_outbox}}} is used to identify messages which need to be routed externally & store delivery statuses. * Fields: message_id, pe_contact_id, status * Table {{{msg_read_status}}} is used to show that a message has been read by a user. * Fields: message_id, auth_user_id ('read' is assumed) * Q: Do we mark as read if pe_contact_id status suggests person has received message? (Fran thinks not) * Good to have UI to 'Mark Unread' * Parser has hooks for modules to plug-into? * Q: Do we treat a pentity the same way as any other resource? * Just that when a message is routed to them, it not only tags but also creates an entry in {{{msg_outbox}}}, which is scanned by the Cron task for 'pending' messages to be sent out. * {{{s3_rest_controller()}}} is modified to check msg_log for messages tagged to the resource (list) or record (display/update) * Views modified as above * 'Ticketing Module' UI * default view is all un-actioned messages (assigned to this user & unassigned?) * If a message is routed to a resource/pentity, this results in a 'create' form popup with as many fields auto-populated as possible (subject into 'name' field & body into 'comments' field, if nowhere better) * See 'Create Report' in [http://ushahidi.com/media/c_How-To-Approve-SMS.pdf Ushahidi] for an example of the workflow here. * Q: If a message is routed to a resource, does this automatically mark ticket as 'actioned'? Provide a popup to ask this? * [BluePrintAuthorization#SpecificExamples Auth restrictions] * Message settings (Gateway) is a 1-1 component of Organisation, Office & Person * When Messages are sent, Person settings are checked, if not found then Office settings are checked, if not found then Organisation settings are checked, if not found then Default settings are used. For speed, all records are read when daemon launched & stored in session.s3.msg. An oncreate/onupdate/ondelete callback forces a refresh of this session data. * Gateway usage should be auditable for billing purposes (i.e. allow a recharge) == User Interface == The home page should be a common Inbox view which, by default, shows all new unread Items (the 'Ticketing Module'). Users/Groups should be able to subscribe to incoming messages of a certain type (Project / Location / Organisation) & have these messages forwarded via SMS / Email / Twitter / etc. Ideally there should be the ability to launch a popup/ticker to notify of new items & a portlet which can be on a user's dashboard when they login. The 'Send Message/Alert' screen should have a small box to enter the Plain-text message which is sent to all recipients (using all available SMS/Email addresses in the Group specified). There should be a 2nd box to create a Rich-text message, with the option of adding attachments. This content just gets sent to those members of the group with an Email address specified. If a user is added to a group we warn about any missing details, but still allow addition (the ref is by pe_pentity.id so addresses can be added/changed later anyway). When sending we need to provide warning messages about users for whom details weren't available.
