Passing same value to multiple tasks in locust - locust

Question

We have a requirement where we need to send a post request and then send a delete request for the same end point(REST API).
Need to generate a unique id for each post request, for each user in each iteration.
generated unique string is put inside on_start() method of task class (SequentialTaskSet).
Problem is, it runs for one iteration, but generates same id for consecutive iterations for each user.
To get unique id for each user in each iteration, generating the unique string within the task itself works, but issue here is, I could not pass the same Id to next task where I need to send delete request.
This is what code looks like now:
class StudentClass(SequentialTaskSet):
rndString = None
def on_start(self):
self.rndString = str(uuid.uuid4())
#task
def postRequest(self):
endpoint = "/students"
headers = {
'Authorization': 'Bearer token',
'content-type': 'application/json', 'accept': 'application/json'
}
data = {
"Id": f'std-{self.rndString}',
}
with self.client.post(endpoint, name="Post request", headers=headers, data=json.dumps(data),
catch_response=True) as response:
........
Appreciate any help in achieving this.

Answer 1

I think if you don't need to call post and delete requests with different weights you can do both calls in same task. Is there something I am missing that requires you to separate tasks for post and delete calls? If yo do need to separate them you can update the self.rndString in post task and it will use the updated one in delete.

#task(1)
def hello_world(self):
response = self.client.get("/listing")
print(response.text)
#task
def fill_crud(self):
response = self.client.post('/api/fill_post/', {"number_1": 76, "number_2": 897, "number_3": 564, "text_4": "Sneha"})
print(response.status_code)
res = json.loads(response.text)
response_id = (res['id'])
response_put = self.client.put(f'/api/fill_post/{response_id}/', {"number_1": 76576, "number_2": 89657, "number_3": 5654, "text_4": "Sneha"})
response_patch = self.client.patch(f'/api/fill_post/{response_id}/', {"text_4": "Suveksha"})
response_delete = self.client.delete(f'/api/fill_post/{response_id}/')
You can try it in this way, I hope it will helps anyone.
