Customs email headers and/or subjects tags

XioNoX · 25 يونيو 2014، 8:24م

Hi!

To be able to sort automatically notification emails sent by Discourse, it would be great if they could have customs headers (or a subject tag) based on the message’s content/content:

For example, here is a list of headers Bugzilla sends with each notification email:

X-Bugzilla-Reason: CC AssignedTo
X-Bugzilla-Type: dep_changed
X-Bugzilla-Watch-Reason: None
X-Bugzilla-Classification: Other
X-Bugzilla-ID: 1014331
X-Bugzilla-Product: mozilla.org
X-Bugzilla-Component: Server Operations
X-Bugzilla-Version: other
X-Bugzilla-Keywords:
X-Bugzilla-Severity: normal
X-Bugzilla-Who: foobar@email.com
X-Bugzilla-Status: RESOLVED
X-Bugzilla-Resolution: FIXED
X-Bugzilla-Priority: –
X-Bugzilla-Assigned-To: email@email.com
X-Bugzilla-Target-Milestone: —
X-Bugzilla-Flags:
X-Bugzilla-OS: Linux
X-Bugzilla-Changed-Fields: Status Resolution
X-Bugzilla-Changed-Field-Names: bug_status resolution

Thanks!

          # Two behaviors in the mail gem collide:
          #
          #  1. Attachments are added as extra parts at the top level,
          #  2. When there are both text and html parts, the content type is set
          #     to 'multipart/alternative'.
          #
          # Since attachments aren't alternative renderings, for emails that contain
          # attachments and both html and text parts, some coercing is necessary.

            @message.header[key] = value.gsub!("%{reply_key}", reply_key) if reply_key.present?
          end

سأحاول الحصول على مزيد من التفاصيل من فريق Discourse حول كيفية استخدام الإعداد المقصود وما هي القيم التي يمكن استبدالها في الترويسات المخصصة.

              augmented_template_args = @template_args.merge({
                site_name: @template_args[:email_prefix],
                optional_re: @opts[:add_re_to_subject] ? I18n.t('subject_re') : '',
                optional_pm: @opts[:private_reply] ? @template_args[:subject_pm] : '',
                optional_cat: @template_args[:show_category_in_subject] ? "[#{@template_args[:show_category_in_subject]}] " : '',
                optional_tags: @template_args[:show_tags_in_subject] ? "#{@template_args[:show_tags_in_subject]} " : '',
                topic_title: @template_args[:topic_title] ? @template_args[:topic_title] : '',
              })

هناك بعض التعقيد مع القوالب مقابل إعداد email_subject الذي لا أفهمه تمامًا - يبدو أن الأخير لا يُستخدم إذا كان هناك قالب، ولكني لست متأكدًا من متى لا يكون هناك قالب! ولكن بصرف النظر عن ذلك، فإن الشيء الأساسي هو أنه إذا كانت الوظيفة التي بنت الرؤوس المخصصة تستخدم نفس القوالب، فسيعمل هذا ويمكن أن تحتوي الرؤوس المخصصة على معلومات ديناميكية مفيدة.
