问题 After successfully joining two db tables, I'm trying to read the data from the 2nd table by addressing the first. I'm addressing opinion.topic_name from my jinja2 template, but nothing is returned. How can I access the Topic.topic_name value from the joined query? view @main.route('/', methods=['GET', 'POST']) def index(): form = IndexForm() opinions = [] if form.validate_on_submit(): opinions = Opinion.query .filter_by(party_id=form.party.data) .filter_by(topic_id=form.topic.data) .join(

问题 I'm using Flask and Flask-WTF and I need to create a form that contains several blocks (subforms) of a similar structure (like a subform with one SelectField and one TextAreaField ). As the docs suggest, I can use FormField together with FieldList to achieve this goal. However, I need to tweak my SelectField 's dynamically (changing their choice s at runtime according to values in the database). The docs now suggest Note that the choices keyword is only evaluated once, so if you want to make

问题 I making a gender form using Flask-WTF , here is the snippet of my code: class Gender(enum.Enum): Male = 'Male' Female = 'Female' def __str__(self): return self.value gender = [(str(y), y) for y in (Gender)] class EditStudentForm(Form): gender = SelectField('Gender', choices=gender) @app.route('/edit_student') def edit_student(): student = Student.query.filter_by(id=student_id).first() student_form = EditStudentForm() # ... validate on submit # .... # .... return render_template(student

问题 I'm currently building a login for a webapp using Flask-Security (which includes Flask-WTForms, Flask-SQLalchemy and Flask-Login). I've been able to fairly painlessly set up the majority of my login flow, including forgotten password; however I want to make it so that the only way users can be registered is through a page only accessible to the admins. I've managed to configure Roles (Admin, User) and set up the following view: @app.route('/adminregister') @roles_accepted('admin') def

问题 This question already has answers here : Using Flask-WTForms, how do I style my form section of the html? (2 answers) Closed 3 years ago . I am following this tutorial http://flask.pocoo.org/docs/0.10/patterns/wtforms/ Here’s an example _formhelpers.html template with a macro: {% macro render_field(field) %} <dt>{{ field.label }} <dd>{{ field(**kwargs)|safe }} {% if field.errors %} <ul class=errors> {% for error in field.errors %} <li>{{ error }}</li> {% endfor %} </ul> {% endif %} </dd> {%

问题 I have a Flask-WTF form for sign in. Apparently the form is never valid, no matter what I enter "success" is never printed. Why isn't my form validating? class loginForm(Form): email = EmailField('email', validators=[InputRequired("Please enter your email address."), Email("Please enter a valid email address.")]) password = PasswordField('password', validators=[InputRequired("Please enter your password.")]) @app.route('/sign-in', methods=['POST', 'GET']) def signIn(): form = loginForm(request

问题 A few days ago I have reset my local flask environment without having captured the dependencies via a pip freeze before I deleted it. Hence I had to re-install the latest version of the entire stack. Now out of the blue I am no longer able to validate with forms. Flask claims CSRF would be missing. def register(): form = RegisterForm() if form.validate_on_submit(): ... return make_response("register.html", form=form, error=form.errors) The first time I send a Get I retrieve an empty form

问题 i'm running into issues with the following, and I'm wondering if it is even possible. I have a flask-admin adminview setup, with an extra form field which shows a dropdown based on a specific column (category) in the sql model. See code for clarification: model: class Item(db.Model): id = db.Column(db.Integer, primary_key = True) name = db.Column(db.String(128), index = True) category = db.Column(db.String(16)) I have the extra form field in Flask-Admin as follows: form_extra_fields = {

问题 I'm getting this error only when the field is defined in a form that contains other fields- but when its defined in a it's own form, this error is not generated and it works. Firstly I will show what works successfully: class TrackForm(Form): name = StringField('Name') start = StringField('Start') end = StringField('End') class Merge(Form): item_description = FieldList(FormField(TrackForm), min_entries=1, max_entries=32) view.py @app.route('/test', methods=['GET', 'POST']) def test(): form
