[FIXED] flask jinja2 variable of variable

Issue

I am trying to access a variable of a object in jinja2 using this code:

{% for row in rows.items %}
  <tr>
    {% for column in model_settings['table_columns'] %}
      <td>
        <p>{{ row.column }}</p>
      </td>
    {% endfor %}
  </tr>
{% endfor %}

what I want is if column was username I would want it to give me row.username. sorry for the bad explanation.

Solution

Jinja2 has the builtin attr filter to access an attribute of an object. The name of the attribute can be a static string, or in your case: a string stored in a variable:

{% for row in rows.items %}
  <tr>
    {% for column in model_settings['table_columns'] %}
      <td>
        <p>{{ row|attr(column) }}</p>
      </td>
    {% endfor %}
  </tr>
{% endfor %}
