jinja2.exceptionsUndefinedError

Hello all,

up to the macros video, when I try to locally run the flask app, being roadblocked by the following error:

jinja2.exceptions.UndefinedError: 'forms.register object' has no attribute 'label'

this chunk of code is where the error comes in and program terminates terminates after jinja2 trying to do getattr

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

anyone else had this problem, or has an idea how to fix this?

thanks in advance

James

I'm only just up to this exercise so I'm still pretty new to this but it looks like the error isn't with your macro. It looks like it's saying forms.register has no label attribute. So there might be an error in your forms.py. Does your StringField() have a label:

StringField('FormLabel', validators=[ ... ])

Hello Guy,

thanks, yes there are labels for all the attributes on the register class.

Oddly, after I posted this on retrying over a few days, this error stopped happening, now I am stuck on an unexpected '}' which I cannot quite locate in the .html files or elsewhere, still its good practice I guess reading the debugger reports.
