Here is where I create the class BankAccount on line 1:
Class BankAccount():
def__init__(self, name):
self.cust_name = name
self.balance = 0
Here is a class calling BankAccount on line 20:
Class BankAccountRestricted(BankAccount):
def init(self, name):
BankAccount.init(self, name)
Line 32 is:
chris = BankAccountRestricted('Christopher Jones')
My error message is:
Traceback (most recent call last):

class BankAccountRestricted(BankAccount):

I am getting TypeError, when I try to delete Warehouse instance.
Note: If I delete Shop instance, Warehouse under that Shop needs be deleted, that's why I used on_delete=models.CASCADE.
class Warehouse(models.Model):

name = models.CharField(max_length=255)
shop = models.ForeignKey(Shop, on_delete=models.CASCADE)
class WarehouseViewSet(viewsets.ModelViewSet):

serializer_class = serializers.WarehouseSerializer

Found the solution. I did not handle on_delete for Children model.
SOLUTION
class WarehouseChildren(models.Model):
data = models.PositiveIntegerField(default=0)
warehouse = models.ForeignKey(Warehouse, on_delete=models.SET_NULL, null=True)
or
class WarehouseChildren(models.Model):
data = models.PositiveIntegerField(default=0)
warehouse = models.ForeignKey(Warehouse, on_delete=models.CASCADE)

In an older version of Dash, I used to need to be able to say,

Since I upgraded to the new version of Dash, now I get an error on that line:

In case you missed it in the Dash change log, this misspelled fallback was removed in 1.0.0.
The configuration attribute should still supported (as at 1.6.0), you just need to use the right name.
app.config.suppress_callback_exceptions = True
I want locust to be able to login to my web application and start to click in the links inside the web application.
With this code I just get activity for the front page with the login and i don't get any notification from inside the application.
Code:
import random
from locust import HttpLocust, TaskSet, task
from pyquery import PyQuery
class WalkPages(TaskSet):
def on_start(self):
self.client.post("/", {
"UserName": "my#email.com",
"Password": "2Password!",
"submit": "Sign In"
})
self.index_page()
#task(10)
def index_page(self):
r = self.client.get("/Dashboard.mvc")
pq = PyQuery(r.content)
link_elements = pq("a")
self.urls_on_current_page = []
for l in link_elements:
if "href" in l.attrib:
self.urls_on_current_page.append(l.attrib["href"])
#task(30)
def load_page(self):
url = random.choice(self.urls_on_current_page)
r = self.client.get(url)
class AwesomeUser(HttpLocust):
task_set = WalkPages
host = "https://myenv.beta.webapp.com"
min_wait = 20 * 1000
max_wait = 60 * 1000
I get the follow msg in the terminal after the first round.

I takes time but someone may need this. My findings in your code: login requests seems not correct (check mine if correct), you cannot reach a variable defined inside of a function from another function, giving task(10) is not suitable for data setter function. Set urls_on_current_page as a class variable to serve for other class members. See my code and comment:
import random
from locust import HttpLocust, TaskSet, task
from pyquery import PyQuery
class WalkPages(TaskSet):
# define variable here to access them from inside the functions
urls_on_current_page = []
def login(self):
self.client.post("/login", data = {"UserName": "mesutgunes#email.com", "Password": "password"})
def get_urls(self):
r = self.client.get("/Dashboard.mvc")
pq = PyQuery(r.content)
link_elements = pq("a")
for link in link_elements:
if key in link.attrib and "http" not in link.attrib[key]:
# there maybe external link on the page
self.urls_on_current_page.append(link.attrib[key])
