title: How to access dictionary parameters with key containing "." (dots) in Jinja2?
body: <p>if I have structure like this:</p>
  
  <pre><code>parameters = {'key1': {'nested_key2': 'value'}}
  </code></pre>
  
  <p>I know how to access 'value' in Jinja2 template:</p>
  
  <pre><code>template data
  {{ key1.nested_key2 }}
  more template data
  </code></pre>
  
  <p>Can I access in Jinja2 template the 'value' defined in the following structure?</p>
  
  <pre><code>parameters = {'some.key1': {'another.nested_key2': 'value'}}
  </code></pre>
  
  <p>This way causing errors about 'some' being not defined...</p>
  
  <pre><code>template data
  {{ some.key1.another.nested_key2 }}
  more template data
  </code></pre>
  
  <p>So how I can access 'value' in last case from Jinja2 template?</p>
