<h2>Usage<a class="headerlink" href="#usage" title="Permalink to this headline">¶</a></h2>
<p>flask-urls currently provides one function to make dealing with URLs in Flask
applications a bit easier.</p>
<div class="section" id="permalink">
<h3>permalink<a class="headerlink" href="#permalink" title="Permalink to this headline">¶</a></h3>
<p>The <tt class="docutils literal"><span class="pre">permalink</span></tt> decorator was taken from <a class="reference external" href="http://flask.pocoo.org/snippets/6/">this snippet</a> on the Flask site.
It&#8217;s used to wrap functions so they only need to return the arguments to
Flask&#8217;s <tt class="docutils literal"><span class="pre">url_for</span></tt> function, instead of calling the function themselves.</p>
<p>For example, say you have several classes that represents items on your site:</p>
<div class="highlight-python"><div class="highlight"><pre><span class="kn">from</span> <span class="nn">flask</span> <span class="kn">import</span> <span class="n">url_for</span>

<span class="k">class</span> <span class="nc">Event</span><span class="p">(</span><span class="nb">object</span><span class="p">):</span>
    <span class="k">def</span> <span class="nf">__init__</span><span class="p">(</span><span class="bp">self</span><span class="p">,</span> <span class="n">event_id</span><span class="p">):</span>
        <span class="bp">self</span><span class="o">.</span><span class="n">event_id</span> <span class="o">=</span> <span class="n">event_id</span>

    <span class="k">def</span> <span class="nf">link</span><span class="p">(</span><span class="bp">self</span><span class="p">):</span>
        <span class="k">return</span> <span class="n">url_for</span><span class="p">(</span><span class="s">&#39;event&#39;</span><span class="p">,</span> <span class="n">event_id</span><span class="o">=</span><span class="bp">self</span><span class="o">.</span><span class="n">event_id</span><span class="p">)</span>

<span class="k">class</span> <span class="nc">User</span><span class="p">(</span><span class="nb">object</span><span class="p">):</span>
    <span class="k">def</span> <span class="nf">__init__</span><span class="p">(</span><span class="bp">self</span><span class="p">,</span> <span class="n">username</span><span class="p">):</span>
        <span class="bp">self</span><span class="o">.</span><span class="n">username</span> <span class="o">=</span> <span class="n">username</span>

    <span class="k">def</span> <span class="nf">link</span><span class="p">(</span><span class="bp">self</span><span class="p">):</span>
        <span class="k">return</span> <span class="n">url_for</span><span class="p">(</span><span class="s">&#39;profile&#39;</span><span class="p">,</span> <span class="n">username</span><span class="o">=</span><span class="bp">self</span><span class="o">.</span><span class="n">username</span><span class="p">)</span>
</pre></div>
</div>
<p>Using the permalink decorator can make the <tt class="docutils literal"><span class="pre">link</span></tt> functions a bit cleaner:</p>
<div class="highlight-python"><div class="highlight"><pre><span class="kn">from</span> <span class="nn">flaskext.urls</span> <span class="kn">import</span> <span class="n">permalink</span>

<span class="k">class</span> <span class="nc">Event</span><span class="p">(</span><span class="nb">object</span><span class="p">):</span>
    <span class="k">def</span> <span class="nf">__init__</span><span class="p">(</span><span class="bp">self</span><span class="p">,</span> <span class="n">event_id</span><span class="p">):</span>
        <span class="bp">self</span><span class="o">.</span><span class="n">event_id</span> <span class="o">=</span> <span class="n">event_id</span>

    <span class="nd">@permalink</span>
    <span class="k">def</span> <span class="nf">link</span><span class="p">(</span><span class="bp">self</span><span class="p">):</span>
        <span class="k">return</span> <span class="s">&#39;event&#39;</span><span class="p">,</span> <span class="p">{</span> <span class="s">&#39;event_id&#39;</span><span class="p">:</span> <span class="bp">self</span><span class="o">.</span><span class="n">event_id</span> <span class="p">}</span>

<span class="k">class</span> <span class="nc">User</span><span class="p">(</span><span class="nb">object</span><span class="p">):</span>
    <span class="k">def</span> <span class="nf">__init__</span><span class="p">(</span><span class="bp">self</span><span class="p">,</span> <span class="n">username</span><span class="p">):</span>
        <span class="bp">self</span><span class="o">.</span><span class="n">username</span> <span class="o">=</span> <span class="n">username</span>
