Creating forms from a model flask, sqlalchamey, and wtforms

Tag : python , By : Mahyar Sepehr
Date : March 29 2020, 07:55 AM
hop of those help? You've mistakenly used the appengine auto form, not the sqlalchemy one. Take a look at the path in the traceback: wtforms/ext/appengine/db.py. You also seem to be confusing the sqlalchemy support built in to WTForms with the separate WTForms-Alchemy package.
If you want to use the built-in support:
from wtforms.ext.sqlalchemy.orm import model_form

UserForm = model_form(User, _exclude=['_pw_hash'])
from wtforms_alchemy import ModelForm

class UserForm(ModelForm):
    class Meta:
        model = User
        exclude = ['_pw_hash']

Problem with linking forms using Flask and WTForms

Tag : python , By : Senthil

will help you I'm trying to set up a web app that runs methods based on user input. The first page takes the image and amount of images and runs a method with them, the user is then sent to the next form which is a conformation button that confirms they have completed a task outside of the application. However when the confirmation button is pressed the user is redirected the first page where it is shown that they are required to input information into the form even though it has been previously filled out , Don't return Stage2() instead:
from flask import redirect, url_for

def home():
form = SelectImageForm()
if form.validate_on_submit():
    Label_Required = form.ImageLabel.data
    Amount_Required = form.Amount.data
    Cloud_Transfer(form.ImageLabel.data, form.Amount.data)
    flash(f'Searching Labels for {form.ImageLabel.data}!', 'success')
    form = SelectXMLConversion()
    return redirect(url_for('stage2'))
return render_template('home.html', title = 'Label Selection', form=form )

And this my update code to populate dependencies wtforms selecField in my edit page.
@bp.route('/edit_orders/<int:obj_id>/edit', methods=['GET'])
def edit_orders(obj_id):
    orders = Order.query.get(obj_id)
    form = OrderForm(obj=orders)
    form.car.choices = [(c.id, c.car) for c in Car.query.all()]
    form.model.choices = [(m.id, m.model) for m in Model.query.filter(Model.car_id == orders.cars.id).all()]
    form.version.choices = [(v.id, v.version) for v in Version.query.filter(Version.model_id == orders.models.id).all()]

    form.car.default = orders.cars.id
    form.model.default = orders.models.id
    form.version.default = orders.versions.id
    form.customer_name.default = orders.customer_name

    return render_template('edit_order.html', title="Edit Orders", form=form)
