<h3>Create a Feed<a class="headerlink" href="#create-a-feed" title="Permalink to this headline">¶</a></h3>
|
|
<p>To create a feed simply instanciate the FeedGenerator class and insert some
|
|
data:</p>
|
|
<div class="highlight-python"><div class="highlight"><pre><span class="gp">>>> </span><span class="kn">from</span> <span class="nn">feedgen.feed</span> <span class="kn">import</span> <span class="n">FeedGenerator</span>

|
|
<p>Note that for the methods which set fields that can occur more than once in
|
|
a feed you can use all of the following ways to provide data:</p>
|
|
<ul class="simple">
|
|
<li>Provide the data for that element as keyword arguments</li>
|
|
<li>Provide the data for that element as dictionary</li>
|
|
<li>Provide a list of dictionaries with the data for several elements</li>
|
|
</ul>
|
|
<p>Example:</p>
|

<div class="highlight-python"><div class="highlight"><pre><span class="gp">>>> </span><span class="n">fg</span><span class="o">.</span><span class="n">contributor</span><span class="p">(</span> <span class="n">name</span><span class="o">=</span><span class="s">'John Doe'</span><span class="p">,</span> <span class="n">email</span><span class="o">=</span><span class="s">'jdoe@example.com'</span> <span class="p">)</span>

<h3>Generate the Feed<a class="headerlink" href="#generate-the-feed" title="Permalink to this headline">¶</a></h3>

<div class="section" id="add-feed-entries">
|
|
<h3>Add Feed Entries<a class="headerlink" href="#add-feed-entries" title="Permalink to this headline">¶</a></h3>
|
|
<p>To add entries (items) to a feed you need to create new FeedEntry objects
|
|
and append them to the list of entries in the FeedGenerator. The most
|
|
convenient way to go is to use the FeedGenerator itself for the
|
|
instantiation of the FeedEntry object:</p>
|
|
<div class="highlight-python"><div class="highlight"><pre><span class="gp">>>> </span><span class="n">fe</span> <span class="o">=</span> <span class="n">fg</span><span class="o">.</span><span class="n">add_entry</span><span class="p">()</span>
|
|
<span class="gp">>>> </span><span class="n">fe</span><span class="o">.</span><span class="n">id</span><span class="p">(</span><span class="s">'http://lernfunk.de/media/654321/1'</span><span class="p">)</span>
|
|
<span class="gp">>>> </span><span class="n">fe</span><span class="o">.</span><span class="n">title</span><span class="p">(</span><span class="s">'The First Episode'</span><span class="p">)</span>
|
|
</pre></div>
|
|
</div>
|
|
<p>The FeedGenerators method add_entry(...) without argument provides will
|
|
automatically generate a new FeedEntry object, append it to the feeds
|
|
internal list of entries and return it, so that additional data can be
|
|
added.</p>
|
|
</div>
|
|
<div class="section" id="extensions">
|
|
<h3>Extensions<a class="headerlink" href="#extensions" title="Permalink to this headline">¶</a></h3>
|
|
<p>The FeedGenerator supports extension to include additional data into the XML
|
|
structure of the feeds. Extensions can be loaded like this:</p>
|
|
<div class="highlight-python"><div class="highlight"><pre><span class="gp">>>> </span><span class="n">fg</span><span class="o">.</span><span class="n">load_extension</span><span class="p">(</span><span class="s">'someext'</span><span class="p">,</span> <span class="n">atom</span><span class="o">=</span><span class="bp">True</span><span class="p">,</span> <span class="n">rss</span><span class="o">=</span><span class="bp">True</span><span class="p">)</span>
|
|
</pre></div>
|
|
</div>
|
|
<p>This will try to load the extension “someext” from the file
|
|
<cite>ext/someext.py</cite>. It is required that <cite>someext.py</cite> contains a class named
|
|
“SomextExtension” which is required to have at least the two methods
|
|
<cite>extend_rss(...)</cite> and <cite>extend_atom(...)</cite>. Although not required, it is
|
|
strongly suggested to use BaseExtension from <cite>ext/base.py</cite> as superclass.</p>
|
|
<p><cite>load_extension(‘someext’, ...)</cite> will also try to load a class named
|
|
“SomextEntryExtension” for every entry of the feed. This class can be
|
|
located either in the same file as SomextExtension or in
|
|
<cite>ext/someext_entry.py</cite> which is suggested especially for large extensions.</p>
|
|
<p>The parameters <cite>atom</cite> and <cite>rss</cite> tell the FeedGenerator if the extensions
|
|
should only be used for either ATOM or RSS feeds. The default value for both
|
|
parameters is true which means that the extension would be used for both
|
|
kinds of feeds.</p>
|
|
<p><strong>Example: Produceing a Podcast</strong></p>
|
|
<p>One extension already provided is the podcast extension. A podcast is an RSS
|
|
feed with some additional elements for ITunes.</p>
|
|
<p>To produce a podcast simply load the <cite>podcast</cite> extension:</p>
|
|
<div class="highlight-python"><div class="highlight"><pre><span class="gp">>>> </span><span class="kn">from</span> <span class="nn">feedgen.feed</span> <span class="kn">import</span> <span class="n">FeedGenerator</span>
|
|
<span class="gp">>>> </span><span class="n">fg</span> <span class="o">=</span> <span class="n">FeedGenerator</span><span class="p">()</span>
|
|
<span class="gp">>>> </span><span class="n">fg</span><span class="o">.</span><span class="n">load_extension</span><span class="p">(</span><span class="s">'podcast'</span><span class="p">)</span>
|
|
<span class="gp">...</span>
|
|
<span class="gp">>>> </span><span class="n">fg</span><span class="o">.</span><span class="n">podcast</span><span class="o">.</span><span class="n">itunes_category</span><span class="p">(</span><span class="s">'Technology'</span><span class="p">,</span> <span class="s">'Podcasting'</span><span class="p">)</span>
|
|
<span class="gp">...</span>
|
|
<span class="gp">>>> </span><span class="n">fg</span><span class="o">.</span><span class="n">rss_str</span><span class="p">(</span><span class="n">pretty</span><span class="o">=</span><span class="bp">True</span><span class="p">)</span>
|
|
<span class="gp">>>> </span><span class="n">fg</span><span class="o">.</span><span class="n">rss_file</span><span class="p">(</span><span class="s">'podcast.xml'</span><span class="p">)</span>
|
|
</pre></div>
|
|
</div>
|
|
<p>Of cause the extension has to be loaded for the FeedEntry objects as well
|
|
but this is done automatically by the FeedGenerator for every feed entry if
|
|
the extension is loaded for the whole feed. You can, however, load an
|
|
extension for a specific FeedEntry by calling <cite>load_extension(...)</cite> on that
|
|
entry. But this is a rather uncommon use.</p>
|
|
<p>Of cause you can still produce a normal ATOM or RSS feed, even if you have
|
|
loaded some plugins by temporary disabling them during the feed generation.
|
|
This can be done by calling the generating method with the keyword argument
|
|
<cite>extensions</cite> set to <cite>False</cite>.</p>
