Flask NameError: while flask_wtf 和 FlaskForm

Question

I usually have no problem adding forms to flask pages however this time I'm really struggling to find the specific issue.

Here are the details of my route:

@app.route("/add_recipe")
def add_recipe():
    form = abcForm()
    return render_template('add_recipe.html', title="Recipe", form= form)

Here is my form class

class abcForm(FlaskForm):
    email = StringField('Email', validators=[DataRequired(), Email()])
    password = PasswordField('Password',validators=[DataRequired()])
    remember = BooleanField('Remember Me')
    submit = SubmitField('Login Up')

The error message I get is "NameError: name 'abcForm' is not defined"

Answer 1

Check to see if you are importing your form class into your route file.

from form-file-name import abcForm

Another thing to check, in your jinja template are you referring to your form as 'abcForm' instead of 'form'? It should be 'form' in jinja since you save it into form in your route.
