25




26




27
But Redmine 0.7.x releases are not. Please freeze your rails to 2.0.2 version:<br />





28
<pre>$ rake rails:freeze:edge TAG=rel_2-0-2</pre>

        <p>You have to specify the socket location in <code>config/database.yml</code>.<br />

44




45




46
        <p>You're running Rails 1.1.x but Redmine requires 1.2.6.<br />





47
Upgrade Rails (if you're using gem package system, run the command <code>gem update</code> as root/administrator).</p>

        <h3><a name="8" class="wiki-page"></a>I upgraded Rails to 2.0, but Redmine doesn't work anymore!</h3>





58




59




60
        <p>Redmine 0.6.3 is Rails 2.0 compatible, but prior versions are not.</p>





61




62




63
        <p>The best solution is to upgrade Redmine to the latest version. But if you really want to use Redmine 0.6.0 on a box running Rails 2.0, please freeze your Rails version for Redmine (it won't affect your other Rails applications) by typing this command from your Redmine directory:</p>





64




65




66
        <pre><code>rake rails:freeze:edge TAG=rel_1-2-6</code></pre>





67

        <p>Don't forget to restart your server.</p>

76




77




78
        <p>Once you've created a new issue status, you need to include it in the workflow.</p>





79




80




81
        <p>Say you have created a status named 'In progress' and you want the developers to be able to change bugs from 'New' to 'In progress'.<br />





82
Go to "Admin -> Issue tracking -> Workflow", select 'Bug' and 'Developer' then click edit.<br />





83
You now see all the transitions allowed for developers on bugs. Check the 'New' -> 'In progress' checkbox and save.</p>

        <h3><a name="11" class="wiki-page"></a>How does "Related issues" work?</h3>





90




91




92
        <p>Using Issue <del><a href="/issues/show/100" class="issue closed" title="New Project - subproject list should not show archived projects (Closed)">#100</a></del> as the one you set the relationship and Issue <del><a href="/issues/show/101" class="issue closed" title="New Issue Drop Down only display for Project Administrator (Closed)">#101</a></del> as the "related to"</p>





93




94




95
        <ul>





96
        <li>Related - Just adds a link to the other issue</li>





97
                <li>Duplicates - Links issues so that closing one, will close the other (e.g. closing <del><a href="/issues/show/100" class="issue closed" title="New Project - subproject list should not show archived projects (Closed)">#100</a></del> will close <del><a href="/issues/show/101" class="issue closed" title="New Issue Drop Down only display for Project Administrator (Closed)">#101</a></del>)</li>





98
                <li>Blocks - Indicates that an issue need to be completed before working on the next.</li>





99
                <li>Precedes - Defines an "order", where issue <del><a href="/issues/show/100" class="issue closed" title="New Project - subproject list should not show archived projects (Closed)">#100</a></del> needs to be completed x days before <del><a href="/issues/show/101" class="issue closed" title="New Issue Drop Down only display for Project Administrator (Closed)">#101</a></del> can be started on.</li>

107




108




109
        <p>By default, Redmine fetches the new commits from the repository only when you browse it.</p>





110




111




112
        <p>If you want the commits to be retrieved periodically by Redmine in the background for all your repositories, uncheck 'Autofetch commits' setting and add a cron that runs (with appropriate environment):</p>





113




114




115
        <pre><code>ruby script/runner "Repository.fetch_changesets" -e production</code></pre>

        <h3><a name="14" class="wiki-page"></a>I can't browse my svn repository through redmine</h3>





119




120




121
Check the following:





122
        <ul>





123
        <li>Make sure you're using a svn client and server >= 1.3. Redmine parse the -xml output from subversion, which is a svn 1.3 feature.</li>





124
                <li>Make sure that the web app is able to run the svn binary</li>





125
        </ul>





126




127




128
        <p>If you're accessing the repository over HTTPS:</p>





129




130




131
        <p>The initial import of a subversion repository over https requires that the ssl certificate fingerprint be manually validated and stored in a config-dir accessible by the user running the web server. It is recommended that a directory local to the redmine application root be provided, either as a default (./svn/.subversion) or as a provided parameter in the repository settings for subversion.</p>





132




133




134
        <p>The work around for the certificate acceptance issue is to manually checkout anything from the svn server specifying the local config-dir and accepting the certificate <ins>permanently</ins>.<br />





135
Example:</p>





136




137




138
<pre>





139
$ svn --config-dir ./svn/.subversion co https://svn.mydomain.com/project/trunk delete-me





140




141
Error validating server certificate for 'https://svn.mydomain.com:443':





142
- The certificate is not issued by a trusted authority. Use the





143
fingerprint to validate the certificate manually!





144
- The certificate hostname does not match.





145
- The certificate has expired.





146
Certificate information:





147
- Hostname: svn.mydomain.com





148
- Valid: from Apr 8 12:00:00 2006 GMT until Sep 24 12:00:00 2010 GMT
