Trac is a\ncommunity-tended garden of the bugs people have found and the features Django\nhas decided to add. As in any garden, sometimes there are weeds to be pulled\nand sometimes there are flowers and vegetables that need picking. We need your\nhelp to sort out one from the other, and in the end, we all benefit together.</p>\n<p>他のガーデン同様に、我々も完璧を目指しますが、ケーキを持って食べることもできません。どんな綺麗な庭にも虫がいます。コミュニティーには、-- 善意での悪事 --をしてしまった良き人もいます。コミュニティーが自己管理し、問題を最小限に留め、新たの加入者にイロハを教えるのはコミュニティー全体の責務。</p>\n<p>我々はTracをDjangoの成果を完璧に表現することを目指しますが、限界の存在を理解しています。コミュニティーへTracのメンテナンスを分布する度、間違いが生じることを許容します。何らかの間違いが生じることは想定内なので、Tracは「ほぼ正確」です。間違ってなんぼ、我々は期限を守ってからの完璧主義です。</p>\n<p>We rely on the community to keep participating, keep tickets as accurate as\npossible, and raise issues for discussion on the <a class=\"reference external\" href=\"https://forum.djangoproject.com/\">Django Forum</a> when there is\nconfusion or disagreement.</p>\n<p>Djangoはコミュニティプロジェクトであり、すべての貢献が役立ちます。 <strong>あなた</strong> なしではこれを実現することはできません！</p>\n<section id=\"triage-workflow\">\n<h2>トリアージのワークフロー<a class=\"heading-anchor\" href=\"#triage-workflow\"><span class=\"visually-hidden\">Link to this heading</span><span aria-hidden=\"true\">#</span></a></h2>\n<p>Unfortunately, not all reports in the ticket tracker provide all the\n<a class=\"reference internal\" href=\"/ja/5.2/internals/contributing/bugs-and-features/\"><span class=\"doc\">required details</span></a>. A number of tickets have proposed\nsolutions, but those don't necessarily meet all the requirements <a class=\"reference internal\" href=\"/ja/5.2/internals/contributing/writing-code/submitting-patches/#patch-style\"><span class=\"std std-ref\">adhering\nto the guidelines for contributing</span></a>.</p>\n<p>One way to help out is to <em>triage</em> tickets that have been created by other\nusers.</p>\n<p>Most of the workflow is based around the concept of a ticket's\n<a class=\"reference internal\" href=\"#triage-stages\"><span class=\"std std-ref\">triage stages</span></a>. Each stage describes where in its\nlifetime a given ticket is at any time. Along with a handful of flags, this\nattribute easily tells us what and who each ticket is waiting on.</p>\n<p>Since a picture is worth a thousand words, let's start there:</p>\n<a class=\"reference internal image-reference\" href=\"../../../../../../_images/triage_process.svg\"><img alt=\"Django のチケット トリアージのワークフロー\" src=\"/ja/5.2/_images/triage_process.svg\" style=\"width: 600px; height: 750px;\" />\n</a>\n<p>We've got two roles in this diagram:</p>\n<ul class=\"simple\">\n<li><p>Mergers: people with commit access who are responsible for making the\nfinal decision to merge a change.</p></li>\n<li><p>Ticket triagers: anyone in the Django community who chooses to\nbecome involved in Django's development process.

She removes the two flags.</p></li>\n<li><p>Charlie reviews the pull request and resets the &quot;patch needs improvement&quot;\nflag with another comment about improving the implementation.</p></li>\n<li><p>Alice updates the pull request, fixing the implementation.

The absolute meaning of &quot;accepted&quot; is that the issue\ndescribed in the ticket is valid and is in some stage of being worked on.\nBeyond that there are several considerations:</p>\n<ul>\n<li><p><strong>Accepted + No Flags</strong></p>\n<p>The ticket is valid, but no one has submitted a patch for it yet. Often this\nmeans you could safely start writing a fix for it. This is generally more\ntrue for the case of accepted bugs than accepted features. A ticket for a bug\nthat has been accepted means that the issue has been verified by at least one\ntriager as a legitimate bug - and should probably be fixed if possible.</p>\n<p>For new features, accepted tickets should only exist after the idea has gone\nthrough the appropriate <a class=\"reference internal\" href=\"/ja/5.2/internals/contributing/bugs-and-features/#requesting-features\"><span class=\"std std-ref\">process for suggesting new features</span></a> and received community and <a class=\"reference internal\" href=\"/ja/5.2/internals/organization/#steering-council\"><span class=\"std std-ref\">Steering Council</span></a> approval, or been accepted in a DEP.</p>\n</li>\n<li><p><strong>Accepted + Has Patch</strong></p>\n<p>The ticket is waiting for people to review the supplied solution. This means\ndownloading the patch and trying it out, verifying that it contains tests\nand docs, running the test suite with the included patch, and leaving\nfeedback on the ticket.</p>\n</li>\n<li><p><strong>Accepted + Has Patch + Needs ...</strong></p>\n<p>This means the ticket has been reviewed, and has been found to need further\nwork. &quot;Needs tests&quot; and &quot;Needs documentation&quot; are self-explanatory. &quot;Patch\nneeds improvement&quot; will generally be accompanied by a comment on the ticket\nexplaining what is needed to improve the code.</p>\n</li>\n</ul>\n</section>\n<section id=\"ready-for-checkin\">\n<h3>Ready For Checkin<a class=\"heading-anchor\" href=\"#ready-for-checkin\"><span class=\"visually-hidden\">Link to this heading</span><span aria-hidden=\"true\">#</span></a></h3>\n<p>The ticket was reviewed by any member of the community other than the person\nwho supplied the patch and found to meet all the requirements for a\ncommit-ready contribution. A <a class=\"reference internal\" href=\"/ja/5.2/internals/organization/#mergers-team\"><span class=\"std std-ref\">merger</span></a> now needs to give\na final review prior to being committed.</p>\n<p>There are a lot of pull requests.

These will be reviewed to\nensure they adhere to the <a class=\"reference internal\" href=\"/ja/5.2/internals/contributing/writing-code/submitting-patches/\"><span class=\"doc\">documented guidelines</span></a>.</p>\n<p>The following three fields (Needs documentation, Needs tests,\nPatch needs improvement) apply only if a patch has been supplied.</p>\n</section>\n<section id=\"needs-documentation\">\n<h3>Needs documentation (ドキュメンテーションが必要)<a class=\"heading-anchor\" href=\"#needs-documentation\"><span class=\"visually-hidden\">Link to this heading</span><span aria-hidden=\"true\">#</span></a></h3>\n<p>This flag is used for tickets with patches that need associated\ndocumentation.

Typically those\nissues are bugs causing regressions from earlier versions or potentially\ncausing severe data losses. This attribute is quite rarely used and the vast\nmajority of tickets have a severity of &quot;Normal&quot;.</p>\n</section>\n<section id=\"version\">\n<h3>Version (バージョン)<a class=\"heading-anchor\" href=\"#version\"><span class=\"visually-hidden\">Link to this heading</span><span aria-hidden=\"true\">#</span></a></h3>\n<p>It is possible to use the <em>version</em> attribute to indicate in which\nversion the reported bug was identified.</p>\n</section>\n<section id=\"ui-ux\">\n<h3>UI/UX<a class=\"heading-anchor\" href=\"#ui-ux\"><span class=\"visually-hidden\">Link to this heading</span><span aria-hidden=\"true\">#</span></a></h3>\n<p>This flag is used for tickets that relate to User Interface and User\nExperiences questions.

This can be\nuseful, for example, to group several tickets on the same theme. Keywords can\neither be comma or space separated. Keyword search finds the keyword string\nanywhere in the keywords. For example, clicking on a ticket with the keyword\n&quot;form&quot; will yield similar tickets tagged with keywords containing strings such\nas &quot;formset&quot;, &quot;modelformset&quot;, and &quot;ManagementForm&quot;.</p>\n</section>\n</section>\n<section id=\"closing-tickets\">\n<span id=\"id2\"></span><h2>チケットを閉じる<a class=\"heading-anchor\" href=\"#closing-tickets\"><span class=\"visually-hidden\">Link to this heading</span><span aria-hidden=\"true\">#</span></a></h2>\n<p>When a ticket has completed its useful lifecycle, it's time for it to be\nclosed. Closing a ticket is a big responsibility, though. You have to be sure\nthat the issue is really resolved, and you need to keep in mind that the\nreporter of the ticket may not be happy to have their ticket closed (unless\nit's fixed!). If you're not certain about closing a ticket, leave a comment\nwith your thoughts instead.</p>\n<p>If you do close a ticket, you should always make sure of the following:</p>\n<ul class=\"simple\">\n<li><p>issue が本当に解決したかよく確認してください。</p></li>\n<li><p>チケットを閉じる決定について説明するコメントを残してください。</p></li>\n<li><p>チケットを再び開いて改善できる方法がある場合には、他の人に知らせてください。</p></li>\n<li><p>If the ticket is a duplicate, reference the original ticket. Also\ncross-reference the closed ticket by leaving a comment in the original one\n-- this allows to access more related information about the reported bug\nor requested feature.</p></li>\n<li><p><strong>礼儀正しくする。</strong> チケットが閉じられて嬉しい人はいません。苛々させたり、落胆させてしまうこともあります。Django へのコントリビューションを諦めさせないための一番良い方法は、礼儀正しくフレンドリーに接して、そのチケットや将来の他のチケットの改善方法を提案することです。</p></li>\n</ul>\n<p>チケットは、次のような複数の方法で解決できます。</p>\n<ul class=\"simple\">\n<li><dl class=\"simple\">\n<dt>fixed (修正済み)</dt><dd><p>パッチが Django に展開されて問題が解決したときに使われます。</p>\n</dd>\n</dl>\n</li>\n<li><dl class=\"simple\">\n<dt>invalid (無効)</dt><dd><p>チケットが正しくないことがわかったときに使われます。つまり、チケットに書かれた issue が、実際にはユーザーの間違いの結果だったり、Django とは別の何かに関する問題について書かれている場合や、バグレポートでもフィーチャーリクエストでもない場合 (たとえば、新しいユーザーは、サポートリクエストをチケットとして送ってしまうことがあります) などです。</p>\n</dd>\n</dl>\n</li>\n<li><dl class=\"simple\">\n<dt>wontfix (修正しない)</dt><dd><p>Used when someone decides that the request isn't appropriate for\nconsideration in Django.

An extremely helpful piece of information is the commit that\nintroduced the regression. Knowing the commit that caused the change in\nbehavior helps identify if the change was intentional or if it was an\ninadvertent side-effect. Here's how you can determine this.</p>\n<p>Begin by writing a regression test for Django's test suite for the issue. For\nexample, we'll pretend we're debugging a regression in migrations. After you've\nwritten the test and confirmed that it fails on the latest main branch, put it\nin a separate file that you can run standalone. For our example, we'll pretend\nwe created <code class=\"docutils literal notranslate\"><span class=\"pre\">tests/migrations/test_regression.py</span></code>, which can be run with:</p>\n<div class=\"code-block\" data-language=\"shell\"><div class=\"code-block-toolbar\"><span class=\"code-block-language\">Shell</span><button type=\"button\" class=\"copy-button\" data-copy hidden><span class=\"copy-button-label\">Copy</span></button></div><pre role=\"group\" tabindex=\"0\" aria-label=\"Shell code\"><code>$<span class=\"w\"> </span>./runtests.py<span class=\"w\"> </span>migrations.test_regression\n</code></pre></div>\n<p>Next, we mark the current point in history as being &quot;bad&quot; since the test fails:</p>\n<div class=\"code-block\" data-language=\"shell\"><div class=\"code-block-toolbar\"><span class=\"code-block-language\">Shell</span><button type=\"button\" class=\"copy-button\" data-copy hidden><span class=\"copy-button-label\">Copy</span></button></div><pre role=\"group\" tabindex=\"0\" aria-label=\"Shell code\"><code>$<span class=\"w\"> </span>git<span class=\"w\"> </span>bisect<span class=\"w\"> </span>bad\nYou<span class=\"w\"> </span>need<span class=\"w\"> </span>to<span class=\"w\"> </span>start<span class=\"w\"> </span>by<span class=\"w\"> </span><span class=\"s2\">&quot;git bisect start&quot;</span>\nDo<span class=\"w\"> </span>you<span class=\"w\"> </span>want<span class=\"w\"> </span>me<span class=\"w\"> </span>to<span class=\"w\"> </span><span class=\"k\">do</span><span class=\"w\"> </span>it<span class=\"w\"> </span><span class=\"k\">for</span><span class=\"w\"> </span>you<span class=\"w\"> </span><span class=\"o\">[</span>Y/n<span class=\"o\">]</span>?<span class=\"w\"> </span>y\n</code></pre></div>\n<p>Now, we need to find a point in git history before the regression was\nintroduced (i.e. a point where the test passes). Use something like\n<code class=\"docutils literal notranslate\"><span class=\"pre\">git</span> <span class=\"pre\">checkout</span> <span class=\"pre\">HEAD~100</span></code> to check out an earlier revision (100 commits earlier,\nin this case). Check if the test fails.
