From 76cce7acf79947e07b51a8baf03a4956fd7e7171 Mon Sep 17 00:00:00 2001 From: "Jonathan S. Katz" Date: Tue, 12 Feb 2019 20:50:48 +0100 Subject: [PATCH 1/2] Create Release Notes archive in the Documentation section. This creates a consolidated area to reference all of the notes from previous releases of PostgreSQL, as current releases only keep the the notes for that specific major release of PostgreSQL. --- media/css/main.css | 15 ++++++ pgweb/core/templatetags/pgfilters.py | 9 ++++ pgweb/docs/views.py | 95 ++++++++++++++++++++++++++++++++ pgweb/urls.py | 2 + pgweb/util/contexts.py | 1 + pgweb/util/db.py | 7 +++ templates/docs/release_notes.html | 102 +++++++++++++++++++++++++++++++++++ 7 files changed, 231 insertions(+) create mode 100644 pgweb/util/db.py create mode 100644 templates/docs/release_notes.html diff --git a/media/css/main.css b/media/css/main.css index e0462ad2..ec82466b 100644 --- a/media/css/main.css +++ b/media/css/main.css @@ -1294,6 +1294,21 @@ table.sponsor-table tbody tr td:nth-child(3) { width: 30%; } +/** Release Notes */ +#release-notes .navheader, +#release-notes .navfooter, +#release-notes .NAVHEADER, +#release-notes .NAVFOOTER, +#release-notes .titlepage, +#release-notes h1.SECT1, +#release-notes .toc { + display: none; +} + +#release-notes .version-list h2:after { + content: none; +} + /** ALL RESPONSIVE QUERIES HERE */ /* Small devices (landscape phones, 576px and up)*/ diff --git a/pgweb/core/templatetags/pgfilters.py b/pgweb/core/templatetags/pgfilters.py index 13f2470c..4edeb95c 100644 --- a/pgweb/core/templatetags/pgfilters.py +++ b/pgweb/core/templatetags/pgfilters.py @@ -70,3 +70,12 @@ def dictlookup(value, key): @register.filter(name='json') def tojson(value): return json.dumps(value) + +@register.filter() +def release_notes_pg_minor_version(minor_version, major_version): + """Formats the minor version number to the appropriate PostgreSQL version. + This is particularly for very old version of PostgreSQL. + """ + if str(major_version) in ['0', '1']: + return str(minor_version)[2:4] + return minor_version diff --git a/pgweb/docs/views.py b/pgweb/docs/views.py index 4577f0ce..36895fcc 100644 --- a/pgweb/docs/views.py +++ b/pgweb/docs/views.py @@ -13,6 +13,7 @@ from pgweb.util.helpers import template_to_string from pgweb.util.misc import send_template_mail from pgweb.core.models import Version +from pgweb.util.db import exec_to_dict from .models import DocPage from .forms import DocCommentForm @@ -140,6 +141,100 @@ def manualarchive(request): 'versions': [_VersionPdfWrapper(v) for v in versions], }) +def release_notes(request, major_version=None, minor_version=None): + """Contains the main archive of release notes.""" + # this query gets a list of a unique set of release notes for each version of + # PostgreSQL.
