OG Views Calendar - tab and block - making it work.

>>>
<p>Using a $view->url of 'node/$node-class/calendar' and tabs, I provide a Calendar tab on node/$node-class. $node-<type> is I believe an undocumented Views feature that works like $node, but for a specific content type -- keeping the Calendar tab from appearing for other content types.</type></p>
<p><strong>Views Argument</strong></p>
<p>To get the calendar tab to work properly, I have to use this custom Views Argument:</p>
<div class="codeblock">

<p>.. the getdate() essentially simulating the URL of 'node/68338/calendar/2008/03/all' because for some reason, 'node/68338/calendar' alone gives me a calendar, but without events. <em>A bug for a different day.</em></p>
<p>(The $viewtype .. part checks if the node we are viewing is part of a group and passes the first group there as the argument, so the block can work if we are viewing something owned by the group.)</p>
<p><strong>Block</strong></p>
<p>The block is tricky. This bit of code on line 20 of calendar.inc -- _calendar_views_query_alter, is causing problems:</p>
<p>$view->args = explode('/', str_replace($view->url .'/', '', $_GET['q']));</p>
<p>It's essentially overriding my $args above, including the $gid. I end up with a block calendar with a week view that says something along the lines of "March 8338" where 8338 is the last 4 digits of the group nid.</p>
<p>This line falls under "if ($view->build_type == 'block') {" -- but my feeble mind cannot comprehend why we would want to rely on $_GET['q'] for parsing arguments to a block. If the arguments for the block match $_GET[q], then we are likely viewing the full-size calendar already?</p>
<p>In any case, my solution was to comment this line out. I am setting $view->args in the Views Arguments Code and do not want it overridden without consideration.</p>
<p>Commenting out that line, then applying this fix -- <a href="http://drupal.org/node/227443">http://drupal.org/node/227443</a> and the block now displays on node/$node-class and node/$node-classtrip.</p>
<p>Clicking on a date or using the « and » navigators brings me to that date on the full tab, which is fine in my case.</p>
<p><strong>The $node-type dilemma</strong></p>
<p>The last remaining problem I have is with using $node-class.</p>
<p>If I use 'node/$arg/calendar' -- the Calendar tab appears on every node, every content type.<br>
If I use 'node/$node/calendar' -- again, the tab appears on every node, every content type.<br>
If I use 'node/$group/calendar' -- no tabs/page available.<br>
If I use '$group/calendar' -- again, no tabs or page. The block also breaks in this case.</p>
<p>That leaves 'node/$node-class/calendar' -- where 'class' is the content type. The tab only appears on class nodes. The block works.</p>
<p>.. and this brings up a new problem.</p>
<p><strong>Nasty Hacks</strong></p>
<p>All links generated by Views Calendar in the block are broken. They attempt to link to the literal 'node/$node-class/calendar/2008/03/all' -- instead of replacing $node-class with the proper ID.</p>
<p>Some consideration has been made for using node/$node/calendar and such, according to calendar.module:</p>

<p>As you can see, this requires modification to support $node-type by any means. In my case, I opted to add $node-class to that array. I could have pulled a list of available content types and checked them all, or used strpos to locate $node and yank that part out of the array, but alas .. I'm not even yet certain if this is the direction I should be heading. I'm just knocking down walls..</p>
<p>Unfortunately, this still doesn't solve the problem entirely. The « prev, next » and iCal links of the calendar block still include the literal '$node-class' in them. </p>
<p>Tracking through iCal reveals what is possibly the problem.</p>

<p>views_get_url is not aware of $node-host nor $args[0] being the $gid.</p>
<p>The resulting iCal URL ends up looking like: </p>
<p>node/%24node-class/calendar/68338/2008/March/all/ical</p>
<p>Perhaps we should be passing $url or filtering $args through calendar_real_url first.</p>
<p>Out of time for now, I will figure this out tomorrow and post.</p>
