I'm facing some troubles by trying to make a like/unlike system for my app.
It's okay when i like/unlike in a normal timelapse, but when i click multiple times in a very short frequency (20 clicks in 10 seconds for example) then my counter is disturbed.
Normally while i'm testing my counter should always have a value of 1 or 0 since i am the only one to do the operation. However when i click quickly and multiple times, my rest api cannot follow the rythm and i'm getting a counter that have 7 or 8 likes.
I've tried multiple solutions. first by adding the model transaction included with django. As a decorator :
#transaction.atomic
Or manually :
with transaction.atomic():
#do stuff
I've also tried to increment directly from the database by using F() :
votes=F("votes") + 1
Nothing seems to work.
Any suggestion ?

I have an API with 59 pages, on each page 1000 rows of data. I would like to retrieve all that data and store it in a Microsoft SQL Server.
When I use tloop with a condition run until i<59, it returns the first 1000 rows of data 59 times which is clearly not what I need.
I have tried to create a global variable next_page but I do not know how to connect it to the next_page present in the API, so that when "next_page"="" the program will know to break the loop.
I had a similar case (difference is that I didn't have a "nextPage" element but a "nextLink" which was giving me the complete URL to get to the nextPage).
I created a globalvariable "endJob" with value "false" at the beginning (tJava right before tLoop)
My tLoop is from int i=1, iteration is i++ , condition is !endJob (thus it will loop as long as the job is not marked as ended).
In a tJava right after tLoop, create the URL for your API request, using your page number, which is the tLoop_1_CURRENT_ITERATION
Then after my tRestClient, I put a tReplicate : first flow is for your needed transformations, the other one retrieve only the "nextPage" item. If nextPage is empty, then you update "endJob" variable to "true" : you want to stop the loop.
I have a situation where i'd like to enter a "3" into a textbox on a user story grid, call something like RankToPosition(3) to move that user story row to position 3 in the current rank. Within the same grid, the idea is to have a textbox on each row, so the row beneath may have a 4 in there, and when i click SUBMIT, the entire table would be processed by using the numbers in the row textbox and calling RankToPosition(#). This is like the Netflix queue. There have been similar questions on here, but my thought is to just call the underlying method alluded to here as "_onMoveToPositionClicked":
https://help.rallydev.com/apps/2.0rc3/doc/source/MoveToPositionMenuItem.html#Rally-ui-menu-item-MoveToPositionMenuItem-cfg-rankRecordHelper
If i could iterate through the table grid, store initial rank values (i realize they're not just integers), and pick the new text values up, run code to call the _onMoveToPositionClicked beneath the scenes, it may accomplish a bulk rank grid for when users have 200+ items to manage, for instance.
Any insight you have for just calling this in custom code would be helpful. Any solution for representing this functionality would be appreciated. I am currently using Rally 2.0rc3.
Thank you for your time
Is it possible to upgrade to a newer version of the App SDK? 2.0rc3 is a very old pre-release. The latest is 2.1: https://help.rallydev.com/apps/2.1/doc/
In any case, the way ranking is performed is relative to another object via the rankAbove or rankBelow parameters. So given the record you want to rerank:
record.save({
params: {
rankAbove: '/hierarchicalrequirement/12345'
}
});
I basically have 4 tags that keep a count of product produced within the company. The problem is that the logic behind these tags is to reset the value when the machine stops. I am not too familiar with coding, but am trying to develop a calculation tag that will just keep a running count without reset. So basically, the number would always escalate.
Tag Names : Filler1Count , Filler2Count, Filler3Count, Filler4Count
This is all done in an application called Historian Administrator. VB code can be implemented behind tags. I will obviously be keeping the original tags, but have the option of making a calculation tag.
Watch for when the number is smaller than the previous poll and store your total in a different variable.
If Filler1Count < LastFiller1Count Then
Filler1Total = Filler1Total + LastFiller1Count
End If
LastFiller1Count = Filler1Count
Total = Filler1Total + Filler1Count
In PsychoPy builder, I have a lot of trials and I want to let the participant take a rest/break part way through and then press SPACE to continue when they're ready.
Any suggestions about how best to do this?
PsychoPy Builder uses the TrialHandler class and you can make use of its attributes to do control when you want to take a rest.
Assuming you're trial loop is utilising an Excel/csv file to get the trial data then make use of trialHandler's attribute : thisTrialN
e.g.
1/ Add a routine containing a text component into your loop (probably at the beginning) with your 'now take a rest...' message and a keyboard component to take the response when they are ready to continue.
2/ Add a custom code component as well and place something similar to this code into its "Begin Routine" tab:
if trials.thisTrialN not in [ int(trials.nTotal / 2) ]:
continueRoutine=False
where 'trials' is the 'name' of your trial loop.
The above will put a rest in the middle of the current set of trials but you could replace it with something like this
if trials.thisTrialN not in [10,20]:
continueRoutine=False
if you wanted to stop after 10 and again after 20 trials.
Note, if you're NOT using an Excel file but are simply using the 'repeat' feature of a simple trial loop, then you'll need to replace thisTrialN with thisRepN
If you're using an Excel file AND reps you'll need to factor in both when working out when you want to rest.
This works by using one of Builder's own variables - continueRoutine and sets it false for most trials so that most of the time it doesn't display the 'take a rest' message.
If you want to understand more, then use the 'compile script' button (or F5) and take a look at the python code that Builder generates for you.
I have a series of 5 tasks, and would like guidance on how to run them in a specified order:
The order that I need:
Run the entire series.
And then only run these:
I checked out this and this resource, but am not sure how to apply them.
I would put all those tasks inside a For Loop Container. The iterations would be controlled by a simple Counter variable and limited for values 1 to 2.
Then for the last two tasks, I would set the Disable property using an expression, e.g.
#[User::Counter] == 2
