Time Tracking and checklists

htdave

Is there a simple example of time tracking?
I want to implement time tracking to go with the tasks on my kanban board.
I would like it so that you can have a button (or 2 separate buttons) to start and stop tracking time on the task.
This would record start and stop times in a Time relationship, which I could then use to calculate and display total time spent on each task, by each user.

Thanks

Well simple is relative 😃 - we have time tracking features inside the time tracker & the ticket system (tickets build upon the time tracker).
Within both applications you do have a 2 button stopwatch, where you have different frontend functions to enter start & end date and a backend function to get things like the time between both values.

I would recommend to check out our time tracker directly - tickets does have to many other functions to serve as a good example 🙂

lsw-fabian Thanks. It looks like there is a lot going on there, but hopefully, I can work it out but by bit

So, I am trying to understand how the "Start" button works.

From what I understand, it runs a front end function, with the following code:

// set now if from time is not set
if(app.get_field_value({F7: 0 slot.time_from}) === null)
app.set_field_value({F7: 0 slot.time_from},
app.call_frontend({lsw_time_tracker.get_seconds_from_midnight_local})
);

app.timer_set('start', false, app.record_save, 500);

From what I can see, the code checks to see if a time has been set, and if not, calls the "get_seconds....local" function, which returns the current time in seconds

what does the final line do - app.timer_set('start', false, app.record_save, 500);

Is this all standard Javascript, or something specific to REI3?

Thanks

The line app.timer_set(... executes another function in 500 milliseconds, in this case a function that saves the current record. You can click on the little question mark icon in your frontend function editor next to every instance function - it will tell you what a function does and what arguments it expects.

REI3 uses plain JavaScript for frontend functions. Functions like app.timer_set() or app.record_save() are so called instance functions. They can be used in all frontend functions and interact with the REI3 system to do things in a standardized way. But you can create your own functions and use most standard JS calls as well. There are some JS objects we block for security reasons (like window/document) - but other than that it´s just JS.

gabriel Thanks for all your help answering my dumb questions.

I am trying to recreate the "Start button in one of my apps.

I have modified the code to:

// set now if from time is not set
if(app.get_field_value({F2: 0 time_tracking.time_start}) === null)
app.set_field_value({F2: 0 time_tracking.time_start},

	app.call_frontend({graytill_task.get_seconds_from_midnight_local})
);

app.timer_set('start', false, app.record_save, 500);

However, when I run the form, clicking on the button does nothing.
If I click preview in the frontend function, F2: 0 time_tracking.time_start does not change to an ID.

Am I missing something obvious?

Thanks

Troubleshooting pieces of code in another´s app is tricky. What you can always do is use the function console.log() to check if/what values are there before and after a change, example: console.log(app.get_field_value({F2: 0 time_tracking.time_start}))

To read the console, open your browsers dev tools (usually F12) and look at the "console" view. Is the function even triggering when you click on the button? Using the console.log() function you can check.

To your code: Why would F2 change to an ID? F2 is a field based on a time attribute and should not take IDs. Time values are integer values (0 would be 00:00:00, 86399 would be 23:59:59).

gabriel Thanks . Opening the console gives me a lot more insight. I have now managed to get my button working.

Sorry again for all the dumb newbie questions. This is a massive learning curve for me, but hopefully it will all be worth it
