Flask, SQLAlchemy: how to use wtforms.ext.sqlalchemy.fields.QuerySelectField for dropdowns
0
I'm new to Flask/SQLAlchemy. I have a database with two tables: Family and Chart. The Family table has two columns: id and familyname. The Chart table has several columns including industry. I was able to display the dropdown for Family/family field, but not the dropdown for Chart/industry field. Here is my code and would appreciate the help.
forms.py
from flask import request
from flask_wtf import FlaskForm
from wtforms import StringField, SubmitField, TextAreaField
from wtforms.ext.sqlalchemy.fields import QuerySelectField
from wtforms.validators import ValidationError, DataRequired, Length
from app.models import Family, Chart
def family_query():
return Family.query.order_by('familyname asc').all()
def industry_query():
return Chart.query(Chart.industry.distinct()).all()
class FamilyForm(FlaskForm):
optsFamily = QuerySelectField(query_factory=family_query,allow_blank=True, get_label='familyname', blank_text="Click to select")
optsIndustry = QuerySelectField(query_factory=industry_query,allow_blank=True, get_label='industry', blank_text="Click to select")
routes.py
from flask import render_template, flash, redirect, url_for, request, g,current_app
from app import db
from app.main.forms import FamilyForm
from app.models import Family, Chart
from app.main import bp
@bp.route('/', methods=['GET', 'POST'])
def index():
form = FamilyForm()
return render_template('index.html', form = form )
HTML
{{ form.csrf_token }}
{{ form.optsFamily }}
<ul>
{% for error in form.optsFamily.errors %}
<li style="color:red;">{{ error }}</li>
{% endfor %}
</ul>
{{ form.optsIndustry }}
<ul>
{% for error in form.optsIndustry.errors %}
<li style="color:red;">{{ error }}</li>
{% endfor %}
</ul>

There should've been an error and you should always include errors with their tracebacks in debugging questions.

The error I got was related to app being aborted but didn't get a message explaining the reason.
