    <p>I'm new to Jinja and just trying to evaluate whether it'll do what I need. </p> <p>Say I have a list of elements, with each element containing a dictionary of key/value pairs. I want Jinja to iterate on blocks for each element in the list, and use the block contents to print the key/value pairs for each dictionary.</p> <p>(I say recursion in the title because my actual implementation uses recursion. With iteration it is the same concept though, so I use it here for simplicity).</p> <p>So, my naive attempt at this would be something like this (this is more or less pseudocode):</p> <p>block.html:</p> <pre><code>{% extends base.html %} {% block element %} &lt;do some fancy printing with the current dictionary here&gt; {% endblock %} </code></pre> <p>base.html:</p> <pre><code>{% for item in seq %} &lt;li&gt;{% block element %}{% endblock %}&lt;/li&gt; {% endfor %} </code></pre> <p>.py file (based off GoogleAppEngine Jinja implementation):</p> <pre><code>myDict = { 'seq': [{'keyA0': 'valueA0', 'keyA1': 'valueA1'}, {'keyB0': 'valueB0', 'keyB1': 'valueB1'}] } template = JINJA_ENVIRONMENT.get_template('block.html') self.response.write(template.render(myDict)) </code></pre> <p>I'm not sure how to structure this to do what I want. I want 'instances' of the blocks to have the appropriate dictionary from the list to print the values, to output something like this:</p> <pre><code>Entry0: keyA0: valueA0 keyA1: valueA1 Entry1: keyB0: valueB0 keyB1: valueB1 </code></pre> <p>But I'm not sure how to pass each block the data it needs. Is this possible with Jinja?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
