I did everything in Pycharm and I got this error: jinja2.TemplateSyntaxError: unkown field render_template.

jinja2.exceptions.TemplateSyntaxError: Encountered unknown tag 'render_field'.

Here is my code for register.html 

{ % from 'macros.html' import render_field %}

<form method="POST" action="" class="form">
    {{ form.hidden_tag() }}
    { % for field in form %}
          {% render_field(field) %}
    { % endfor %}

</form>

here is my macros.html

{% macro render_field(field) %}
        <div class="field">
            {% if field.error %}
                {% for error in field.erros %}
                    <div class="notification error">{{ error}} </div>
                {% endfor %}
            {% endif %}
            {{ field(placeholder= field.label.text) }}
        </div>
{% endmacro %}

Are the spaces in your syntax causing the import to fail?

Replace "{ %" with "{%"

In the video, it looks like statement delimiters are used {{ render_field(field) }} instead of expression delimiters {% render_field(field) %}. See video at time 1:21.
