<h1>Using pokedex<a class="headerlink" href="#using-pokedex" title="Permalink to this headline">¶</a></h1>
|
||
|
|
<p>The pokédex is, first and foremost, a Python library. To get the most of it,
|
||
|
|
you’ll need to learn <a href="#id1"><span class="problematic" id="id2">`Python`_</span></a> and <a href="#id3"><span class="problematic" id="id4">`SQLAlchemy`_</span></a>.</p>
|
||
|
|
<p>Here is a small example of using pokedex:</p>
|
||
|
|
<div class="highlight-python"><div class="highlight"><pre><span class="kn">from</span> <span class="nn">pokedex.db</span> <span class="kn">import</span> <span class="n">connect</span><span class="p">,</span> <span class="n">tables</span><span class="p">,</span> <span class="n">util</span>
|
||
|
|
<span class="n">session</span> <span class="o">=</span> <span class="n">connect</span><span class="p">()</span>
|
||
|
|
<span class="n">pokemon</span> <span class="o">=</span> <span class="n">util</span><span class="o">.</span><span class="n">get</span><span class="p">(</span><span class="n">session</span><span class="p">,</span> <span class="n">tables</span><span class="o">.</span><span class="n">PokemonSpecies</span><span class="p">,</span> <span class="s">'bulbasaur'</span><span class="p">)</span>
|
||
|
|
<span class="k">print</span> <span class="s">u'{0.name}, the {0.genus} Pokemon'</span><span class="o">.</span><span class="n">format</span><span class="p">(</span><span class="n">pokemon</span><span class="p">)</span>
|
||
|
|
</pre></div>
|
||
|
|
</div>
|
||
|
|
<p>Running this will give you some Bulbasaur info:</p>
|
||
|
|
<div class="highlight-none"><div class="highlight"><pre>Bulbasaur, the Seed Pokemon
|
||
|
|
</pre></div>
|
||
|
|
</div>
|
||
|
|
<div class="section" id="connecting">
|
||
|
|
<h2>Connecting<a class="headerlink" href="#connecting" title="Permalink to this headline">¶</a></h2>
|
||
|
|
<p>To get information out of the Pokédex, you will need to create a
|
||
|
|
<tt class="xref py py-class docutils literal"><span class="pre">Session</span></tt>. To do that, use
|
||
|
|
<tt class="xref py py-func docutils literal"><span class="pre">pokedex.db.connect()</span></tt>. For simple uses, you don’t need to give it any
|
||
|
|
arguments: it the database that <tt class="docutils literal"><span class="pre">pokedex</span> <span class="pre">load</span></tt> fills up by default. If you
|
||
|
|
need to select another database, give its URI as the first argument.</p>
|
||
|
|
<p>The object <tt class="xref py py-func docutils literal"><span class="pre">connect()</span></tt> gives you is actually a
|
||
|
|
<a class="reference external" href="http://www.sqlalchemy.org/docs/orm/session.html#sqlalchemy.orm.session.Session" title="(in SQLAlchemy v0.7)"><tt class="docutils literal"><span class="pre">sqlalchemy.orm.session.Session</span></tt></a>, giving you the
|
||
|
|
full power of SQLAlchemy for working with the data. We’ll cover some basics
|
||
|
|
here, but if you intend to do some serious work, do read SQLAlchemy’s docs.</p>
|
||
|
|
<p>XXX: write the rest of this</p>
