I'm a newbie, trying to use Flask with WTForms. My objective is to create a form to edit a user record returned from a database. The following code, mocking the db with an instance of the User class, executes without error for the /form route. No problem. But the form values do not contain pre-populated data for the user to edit!
The /test route returns: TypeError: 'str' object is not callable.
I just want the form to display user data for editing.
Any help would be greatly appreciated.
Here's code from my .py file:

class LogInForm(FlaskForm):
username = StringField('username', [validators.DataRequired()])
password = PasswordField('password', [validators.DataRequired()])
class User():
def __init__(self, name, pwd):
self.name = name
self.pwd = pwd
@app.route('/test', methods=['GET', 'POST'])
def test():
found_user = User("Moe", "2222")
form = LogInForm(obj=found_user)
return render_template('test.html',user=found_user, form=form)
@app.route('/form', methods=['GET', 'POST'])
def form():
user = User("Moe", "2222")
form = LogInForm(obj=user)
if form.validate_on_submit():
return f'The form has been submitted. Username {form.username.data}. Password{form.password.data}'
return render_template('forms.html', form=form)Here's the template for the /form route:form method = "POST" action="{{ url_for('form') }}">
{{ form.csrf_token }}
{% for field in form %}
<p>
{{field.label}}
{{field}}
</p>
{% endfor %}
<input type="submit" value="Submit">
</form>
</body>Here's the template for the /test route:<body>
{% from "_formhelpers.html" import render_field %}
<form method="post">
<dl>
{{ render_field(user.name) }}
{{ render_field(user.pwd) }}
</dl>
<p><input type="submit" value="Submit">

<a href="/">Go to home page.</a>
