Locust - Shape Class ignored when running Web UI with --class-picker

I saw that locust supports defining different user classes and shape classes and that it is possible to choose which one to run through the web-ui when locust is started with --class-picker
However, when I select a user class and a shape class, locust doesn't use the shape and uses only what I type in the "Number of Users" and "Spawn rate" fields on the interface.
How can I make locust use the selected shape file?
This is how my user classes look: (the other user classes are very similar to this one)
from locust import HttpUser, TaskSet, task
from locust import LoadTestShape
import csv
import random
class Tasks1(TaskSet):
DATA = {}
def on_start(self):
if not self.DATA:
self._get_pics()
def _get_pics(self):
with open('targets.csv') as csv_file:
csv_reader = csv.reader(csv_file, delimiter=',', quotechar="'")
for row in csv_reader:
self.DATA['images/' + row[0]] = '{"x":' + row[1] + ',"y":' + \
row[2] + ',"width":' + row[3] + ',"height":' + row[4] + '}'
#task
def service(self):
key = random.choice(list(self.DATA.keys()))
payload = {self.DATA[key]}
with open(key, 'rb') as image:
self.client.post('/process', headers={'Authorization': 'Bearer ' + token, 'Accept-Encoding': 'gzip'}, files={'image': image}, data=payload)
#task
def stop(self):
self.interrupt()
class FirstUser(HttpUser):
tasks = [Tasks1]
And these are the shape classes:
ShapeClass1.py:
from locust import LoadTestShape
class ramp_up_20min_40users_hold_5min_ramp_down_5min_1user(LoadTestShape):
stages = [
{"duration": 1200, "users": 40, "spawn_rate": 0.034},
{"duration": 300, "users": 40, "spawn_rate": 1},
{"duration": 300, "users": 1, "spawn_rate": 0.0325}
]
def tick(self):
run_time = self.get_run_time()
for stage in self.stages:
if run_time < stage["duration"]:
try:
tick_data = (
stage["users"], stage["spawn_rate"], stage["user_classes"])
except:
tick_data = (stage["users"], stage["spawn_rate"])
return tick_data
return None
ShapeClass2.py:
from locust import LoadTestShape
class ramp_up_1min_40users_hold_20min(LoadTestShape):
stages = [
{"duration": 60, "users": 40, "spawn_rate": 0.67},
{"duration": 1200, "users": 40, "spawn_rate": 1},
]
def tick(self):
run_time = self.get_run_time()
for stage in self.stages:
if run_time < stage["duration"]:
try:
tick_data = (
stage["users"], stage["spawn_rate"], stage["user_classes"])
except:
tick_data = (stage["users"], stage["spawn_rate"])
return tick_data
return None
I can see the choices in the UI.
However, the Number of users and spawn rate field are not disabled and locust executes what I type in there and not what is defined in the load shape files.
Am I missing something here?

Import CSV script- make python 2.7 compatible

I created the following script to import files into my django models. It works fine, but only when using python 3.4.
How can I change this script to make it run on 2.7?
Thanks,

id type in mongoengine objects

I use mongoengine and when I call a class mongoengine give me error
for example when I use : Site.objects()
I get this

and it's my class definition :
class Site(db.Document):

pages = db.ListField(ReferenceField(Page))
siteId = db.IntField(required = True , unique = True )

How do I lock these attributes?

I've only just started coding, so I thought I would try and make something simple, however, I can't select the objects from my ls, I know the error is in my def attrLockT and was wondering if anyone could help me to fix this issue and understand what I am doing wrong?
import maya.cmds as cmds
#Selects the attributes
sat = ['.tx', '.ty', '.tz']
sar = ['.rx', '.ry', '.rz']
sas = ['.sx', '.sy', '.sz']
#Creates the list of currently selected objects
myList = cmds.ls(sl = True)
#Lock the translate attributes of the selected objects
def attrLockT(*args):
checkAttr=cmds.getAttr (myList[0] + sat)
if (checkAttr == 0):
cmds.setAttr(myList[0] + sat, lock = 1)
#Delete window if it is already open
if cmds.window('animationCtrl', exists=True):
cmds.deleteUI('animationCtrl', window=True)
#Setup the window
cmds.window(
'animationCtrl',
title = "Animation Controls",
widthHeight = (300, 500),
s = False)
form = cmds.formLayout()
tabs = cmds.tabLayout(innerMarginWidth=5, innerMarginHeight=5)
cmds.formLayout(
form,
edit=True,
attachForm=(
(tabs, 'top', 0),
(tabs, 'left', 0),
(tabs, 'bottom', 0),
(tabs, 'right', 0)))
#Layout for the first tab
child1 = cmds.gridLayout( numberOfRowsColumns=(4, 3) , cwh = (100, 50))
cmds.text(label = "")
cmds.text(label = "Lock", align = "center", h = 20, w = 250)
cmds.text(label = "")
cmds.button(label = "Translate", h = 300, w = 250, c = attrLockT)
cmds.button(label = "Rotate", h = 50, w = 250)
cmds.button(label = "Scale", h = 50, w = 250)
cmds.text(label = "")
cmds.text(label = "Unlock", align = "center", h = 20, w = 250)
cmds.text(label = "")
cmds.button(label = "Translate", h = 50, w = 250)
cmds.button(label = "Rotate", h = 50, w = 250)
cmds.button(label = "Scale", h = 50, w = 250)
cmds.setParent( '..' )
#Layout for the second tab
child2 = cmds.rowColumnLayout(numberOfColumns=3)
cmds.button()
cmds.button()
cmds.button()
cmds.setParent( '..' )
cmds.tabLayout(
tabs,
edit=True,
tabLabel=((child1, 'Lock/Unlock'), (child2, 'Keyable/Unkeyable')))
cmds.showWindow('animationCtrl')
The error that is thrown is
# Error: coercing to Unicode: need string or buffer, list found
# Traceback (most recent call last):
# File "<maya console>", line 16, in attrLockT
# TypeError: coercing to Unicode: need string or buffer, list found

Does this work?
myList[0] + sat
Is myList[0] type of list ? Because the sat variable is certainly list.
If myList is just a list of string then myList[0] will be just one element of type string and it will produce an error.
Simplify your program, just leave only locking routine and window with button to see what will happen, be sure that the right name of an object + attribute is passed to getAttr - just string like 'obj.attrib'.
Some python specific clues for your function
If you need to sum two lists:
[ objName + attName for objName, attName in zip(myList, sat) ]
that will result, for example, in ['obj1.tx', 'obj2.ty', 'obj3.tz']
If you need apply a list of attributes to an object:
[ myList[0] + a for a in sat ]
that will result in ['obj1.tx', 'obj1.ty', 'obj1.tz']
If you need apply the same list of attributes to all objects:
[ objName + attName for objName in myList for attName in sat ]
will result in ['obj1.tx', 'obj1.ty', 'obj1.tz', 'obj2.tx', ..., 'obj3.tz']
Then you can call your locking function over that result list:
def locker(a):
checkAttr = cmds.getAttr(a)
if (checkAttr == 0):
cmds.setAttr(a, lock = 1)
and finally it should look:
def attrLockT(*args):
atrlist = [ ..... ]
for a in atrlist:
locker(a)

Two issues:
first, you want to loop through the individual attributes and concatenate them with object names:
def lockTranslate(*args):
for obj in mylist:
for attr in ['.tx', '.ty', '.tz']:
cmds.setAttr(obj + "." + attr, l=True)
second, and maybe more important, you will likely have problems the scope of your functions. In the form you have it typed in, variables like myList and sat, etc are accessible to the function through closure - it will work if you execute all of this in the listener, but if you break the closure (for example, if this goes into a function that gets called by another function) things wont work -- myList will be stuck pointing at whatever was selected when the function was defined.
In this particular case you probably want to just operate on selection instead of inheriting myList:
def lockTranslate(*args):
for obj in cmds.ls(sl=True, type = 'transform'):
for attr in ['.tx', '.ty', '.tz']:
cmds.setAttr(obj + "." + attr, l=True)

django point definition

my models:
class Mod(models.model)
name = models.CharField(max_length = 255)
co_x = models.DecimalField(max_digits = 11, decimal_places = 8)
co_y = models.DecimalField(max_digits = 11, decimal_places = 8)
my views:
def closedPoint(request):
location_name = str(request.POST.get("lo", default=""))
nokta_x = int(float(request.POST.get("x"))
nokta_y = int(float(request.POST.get("y"))
poi = Point(nokta_x, nokta_y, srid = 900913)
sk = Mod()
poi_s = Point(sk.co_x, co_y, srid = 900913)
resut_poi = Mod.objects.filter(poi_s__distance_lte = (poi, D(km = 7))).filter(name__in = location_name)
here i want to deduct closest point in 7 km but it gives "Invalid parameters given for Point initialization

Ok, so it's now clear your error message comes from initializing a Point class with None.
That is your first critical problem.
Judging by the error message, my guess is that poi_s is initialized with None, None as Mod() is an unsaved instance with no values and those are the invalid parameters.
sk = Mod() # unsaved Mod instance with no defaults
poi_s = Point(sk.co_x, co_y, srid = 900913)
# sk.co_x is None
Your second problem that will appear after fixing the above is querying a model with an invalid lookup type (specific to PointField, __distance) which accepts a tuple. How to solve that, I don't know.
You would have to look at how GeoDjango translates that tuple into a DB lookup.
