copied!<p>If you want to take advantage of CKAN's main navigation menu, it gets a little tricky. (We just had to figure this out. Not sure if we did it the right way, but we did get it to work with CKAN 2.2):</p> <p>First, you need the additional content in your extension path somewhere. Assuming it's at <code>my_extension/amazing.html</code>, you want to add the following to the <b>my_extension/templates/header.html</b> file (in your custom extension):</p> <pre><code>{% ckan_extends %} {% block header_site_navitagtion_tabs %} {{ h.build_nav_main( ('search', _('Datasets')), ('organizations_index', _('Organizations')), ('group_index', _('Groups')), ('about', _('About')), ('amazing', _('Amazing Extension')) ) }} {% endblock %} </code></pre> <p>This will cause a server error, since "amazing" hasn't been registered in pylons as a mapped route. We'll fix that next. If you've built your extension properly, you should have a <b>my_extension/plugins.py</b>, to which you'll need to add the following to your plugin's class definition:</p> <pre><code>class AmazingPlugin(plugins.SingletonPlugin, tk.DefaultDatasetForm): #or plugins.implements(plugins.IRoutes, inherit=True) def before_map(self, m): m.connect('amazing', #name of path route '/amazing', #url to map path to controller='ckanext.my_extension.controller:AmazingController', #controller action='amazing') #controller action (method) return m </code></pre> <p>..where <code>ckanext.my_extension.controller</code> is the include path to <b>my_extension/controller.py</b>, which we'll create next. It should consist of:</p> <pre><code>import ckan.plugins as p from ckan.lib.base import BaseController class AmazingController(BaseController): def amazing(self): return p.toolkit.render('amazing.html') </code></pre> <p>That's it. Now you've got a controller mapping a url to a nav item that you can call with <code>h.build_nav_main()</code>. Simple, right? ;) One last thing. You'll need to restart apache for it to take effect.</p>
