Flask-admin : How to auto update the data in table2 when table1 is edited? - flask

Question

I am using flask-admin and displaying a few custom forms using baseView and once the data is entered and submitted it is getting stored in the tables of the database. Now I want it to update the data across all the tables if an edit is made to a table named 1. I tried using on_model_change() function but it still doesn't work. Even after_model_change() functions aren't working. Is there any fix for this ?
This is my tables or models :
table 1:
class Test1(db.Model):
Test_id = db.Column(
db.Integer, primary_key=True, autoincrement=True)
Test_name = db.Column(db.String(500), nullable=True)
table 2:
class test_details(db.Model):
details_id = db.Column(
db.Integer, primary_key=True, autoincrement=True)
invoice_id = db.Column(db.Integer, nullable=True)
test_name = db.Column(db.String(200), nullable=True)
amount = db.Column(db.Integer, nullable=True)
created_by = db.Column(db.String(100), nullable=True)
created_date = db.Column(db.DateTime(timezone=True),
default=datetime.utcnow, nullable=True)
def __str__(self):
return self.invoice_id
This is my custom view for a form :
class testUserView(BaseView):
def is_accessible(self):
if not current_user.is_active or not current_user.is_authenticated:
return False
if current_user.has_role('superuser') or current_user.has_role('user'):
return True
return False
def after_model_change(self, form, model, is_created):
print("after_model_change called")
if is_created:
print("Hey, new record created with values:")
#expose('/', methods=['GET', 'POST'])
def index(self):
if request.method == 'POST':
data = request.form
# print(data)
generate_id(data)
return jsonify({'success': True})
# return self.render('admin/usertest.html')
speciesData = get_species_table_data()
specimenData = get_specimen_table_data()
locationData = get_location_table_data()
clinicalTestData = get_clinicalTest_table_data()
clinicalTestDatas = json.dumps(clinicalTestData)
return self.render('admin/usertest.html', speciesData=speciesData, specimenData=specimenData, locationData=locationData, clinicalTestData=clinicalTestDatas, admin_base_template=admin.base_template)
admin added view :
admin.add_view(testUserView(name="Create Order",
endpoint='usertest', category='Manage Orders'))
I tried using on_model_change() and after_model_change() functions that act as event handlers for flask-admin. I expected it to print "after_model_change called" but the text is not being displayed on the console meaning the function is not being called. How can I FIX THIS ? PLEASE HELP
