‘module’ object has no attribute ‘MStatus' in Maya python Api 2020

I am trying to build a command in python for Maya following a course on youtube and it's showing this error "# Error: RuntimeError: file line 2: AttributeError: file C:/Users/saeed/OneDrive/Documents/maya/2020/Plugins/vertexParticle.py line 23: 'module' object has no attribute 'MStatus' # "
I checked Maya API documents and we should have "MStatus" class but I have no idea why it's not accepted, I tried to use "MStatusCode" and it's showing same error.

Because MStatus.MStatusCode is an enum, you can return its integer value in Python. The only issue is that because in C++ this is an enum, there is no guarantee that the values won't change/shift between releases. This enum has remained consistent since 2019, so there isn't much risk of this happening for MStatus.MStatusCode.

https://help.autodesk.com/view/MAYAUL/2023/ENU/?guid=Maya_SDK_cpp_ref_class_m_status_html
Somewhere in the top of your file simply add the constants you intend to use:
MStatus_kSuccess = 0
MStatus_kFailure = 1
MStatus_kUnknownParameter = 5
Then return the constant instead in your functions:
if parserArguments.isFlagSet(kHelpFlag):
self.setResult(helpMessage)
return MStatus_kSuccess

Python Json value overwritten by last value

lista =
[{Identity: joe,
summary:[
{distance: 1, time:2, status: idle},
{distance:2, time:5, status: moving}],
{unit: imperial}]
I can pull the data easily and put in pandas. The issue is, if an identity has multiple instances of, say idle, it takes the last value, instead of summing together.
my code...
zdrivershours = {}
zdistance = {}
zstophours = {}
For driver in resp:
driverid[driver['AssetID']] = driver['AssetName']
for value in [driver['SegmentSummary']]:
for value in value:
if value['SegmentType'] == 'Motion':
zdriverhours[driver['AssetID']] = round(value['Time']/3600,2)
if value['SegmentType'] == 'Stop':
zstophours[driver['AssetID']] = round(value['IdleTime']/3600,2)
zdistance[driver['AssetID']] = value['Distance']

To obtain the summatory of distance for every driver replace:
zdistance[driver['AssetID']] = value['Distance']
by
if driver['AssetID'] in zdistance:
zdistance[driver['AssetID']] = zdistance[driver['AssetID']] + value['Distance']
else:
zdistance[driver['AssetID']] = value['Distance']

python peewee dynamically or + and clauses

I'd like to do a and clause with two lists of multiple or clauses from the same table.
The problem with the following code is, that the query result is empty. If I just select 'indices' or 'brokers', the result is fine.
...
query = query.join(StockGroupTicker, on=(Ticker.id == StockGroupTicker.ticker))
# indices
if "indices" in filter:
where_indices = []
for f in filter["indices"]:
where_indices.append(StockGroupTicker.stock_index == int(f))
if len(where_indices):
query = query.where(peewee.reduce(peewee.operator.or_, where_indices))
# broker
if "brokers" in filter:
where_broker = []
for f in filter["brokers"]:
where_broker.append(StockGroupTicker.stock_index == int(f))
if len(where_broker):
query = query.where(peewee.reduce(peewee.operator.or_, where_broker))
return query.distinct()
SQL Querie (update)
# index and brocker
SELECT
DISTINCT `t1`.`id`,
`t1`.`symbol`,
`t1`.`type`,
`t1`.`name`,
`t1`.`sector`,
`t1`.`region`,
`t1`.`primary_exchange`,
`t1`.`currency`,
`t1`.`score`,
`t1`.`last_price`,
`t1`.`last_price_date`,
`t1`.`last_price_check`,
`t1`.`last_stock_split`,
`t1`.`next_earning`,
`t1`.`last_earnings_update`,
`t1`.`disused`,
`t1`.`source`,
`t1`.`source_intraday`,
`t1`.`created`,
`t1`.`modified`,
`t2`.`invest_score` AS `invest_score`
FROM
`ticker` AS `t1`
INNER JOIN `tickerstats` AS `t2` ON
(`t1`.`id` = `t2`.`ticker_id`)
INNER JOIN `stockgroupticker` AS `t3` ON
(`t1`.`id` = `t3`.`ticker_id`)
WHERE
(((((`t1`.`disused` IS NULL)
OR (`t1`.`disused` = 0))
AND (`t2`.`volume_mean_5` > 10000.0))
AND (`t3`.`stock_index_id` = 1))
AND (`t3`.`stock_index_id` = 10)
)

Thanks to #coleifer, the peewee solution is quite simple. I had to use an alias.
if "indices" in filter and filter["indices"]:
query = query.join(
StockGroupTicker, peewee.JOIN.INNER, on=(Ticker.id == StockGroupTicker.ticker)
)
where_indices = []
for f in filter["indices"]:
where_indices.append(StockGroupTicker.stock_index == int(f))
if len(where_indices):
query = query.where(peewee.reduce(peewee.operator.or_, where_indices))
if "brokers" in filter and filter["brokers"]:
BrokerGroupTicker = StockGroupTicker.alias()
query = query.join(
BrokerGroupTicker, peewee.JOIN.INNER, on=(Ticker.id == BrokerGroupTicker.ticker)
)
where_broker = []
for f in filter["brokers"]:
where_broker.append(BrokerGroupTicker.stock_index == int(f))
if len(where_broker):
query = query.where(peewee.reduce(peewee.operator.or_, where_broker))
return query.distinct()

Error in Google Custom Search API nexpage

Normally, data can be obtained without errors, but sometimes the errors below occur.
Traceback (most recent call last):
File "D://Google_Search_API_0.4.py", line 122, in <module>

KeyError: 'nextPage'
It works in the following order.
spider('men shorts', 'adidas', 'yahoo.com') # input query (q,orTerms,siteSearch)
spider(searchterm_in, incl_searchterm_in, sitesearch_in): # first page -> get input query
spider_next_page(service, index, searchterm_in, incl_searchterm_in, sitesearch_in): # next page
If an error occurs, it occurs here.
def spider(searchterm_in, incl_searchterm_in, sitesearch_in):
...
--> nextPageIndex = res['queries']['nextPage'][0]['startIndex']
If I'm right, what's the problem? And why does it sometimes work without errors?

Maybe it is the end of data so there is no more nextPage.
You could use try/except to catch error and skip code.
Or you should run it in if 'nextPage' in res['queries']:
if 'nextPage' not in res['queries']:`
print("The End")
else:
nextPageIndex = response['queries']['nextPage'][0]['startIndex']
nextPageCount = response['queries']['nextPage'][0]['count']

itemsave.append(values_spider_next_page)

spider_next_page(service, nextPageIndex, searchterm_in, incl_searchterm_in, sitesearch_in)

Prevent Double (or more) post in Django

I'm working on a site built in django, but i'm having a little trouble, in multiple parts im getting double (sometimes 3 or 4) post, for example im submitting a form where you need to save a contact, but when the page reloads im getting 2, 3 or 4 of the same contact. The difference in time is about 0.5 secs. of each other.
I tried to code a little solution like this:
def not_double_post(request):
session_data = request.session.get('post_data', None)
session_new_data = '-'.join([str(request.user.username),
str(int(time.time()))])
if session_data is None:
request.session['post_data'] = session_new_data
return True
else:
current_user = request.user.username
current_time = int(time.time())
session_post_user = session_data.split('-')[0]
session_post_time = session_data.split('-')[1]
if current_user == session_post_user:
time_difference = current_time - int(session_post_time)
if time_difference > 10:
request.session.pop('post_data')
request.session['post_data'] = ''.join([str(current_user),
str(int(time.time()))])
return True
else:
return False
else:
return True
On each request.method == 'POST' i check this function, store the user and time when the operation has made in session, if the operation user are the same, and the time difference is less than 10 seconds, is an invalid post.
(I'm also setting the attribute of the button to disabled when the user clicks)
But im getting double post with this. I dont know if this really works like i expect, but it would be good to take another point of view (or another recommendation to achieve this).
Thanks!
