for Responsiveness issues, I think this video might solve it : https://www.youtube.com/watch?v=bam83Xv4VMA it will show how it can be done without media queries.

If you insist on the current behavior, then you'll return 503. This tells the (standard compliant) client that your server is temporarily overloaded, and it can retry later (you can even hint when it can on Retry-After header. While standard-compliant, you'll only want to do this if queuing the process requested by the second call later is impossible, perhaps because the internal state will have changed so the second call is invalid. If it's possible to just queue the process with an identical result as when the client manually retry the call, then just return 202.

Your UserInfo.objects.update(**my_form.cleaned_data) aims to update all records in the database. Since your form includes a primary key (id), it will thus aim to update the id of all records to a given value. Since these values however should be unque, that means it will of course raise an error.

You can prevent that by filtering before the update, like:

Roee.js:: The constructor takes an arg which is used as a function.

Yes. This constructor is sort of using the callback pattern, calling your function with the emit function on the instance of that class. This is an unusual thing to do.

ticker.js:: defines the function which is passed in roee.js. This function takes a parameter, which is again a function, right?

That's correct. In the callback from constructor (which is a bit weird to have), the parameter passed to this callback is a function bound to emit events from the instance of the Roee class.

tester.js: how is this able to access the counter and pass argument to the function "emiff('ticker',tickcnt++)" ?

tickcnt is in the closure set up by the callback function from the constructor. Since tickcnt is referenced from within that setInterval, it won't be garbage collected.

Now, how does that outer code get the value? The code in ticket.js calls the emit method on the Roee class (which is extending event emitter). Anything with a reference to that instance of Roee can add listeners to events, including the ticker event. When that event is fired, the data for the current tick is passed through it.

Really, this code pattern is pretty terrible in general. There are few circumstances where something outside of a class should be triggering events on that class. It's possible I'm not understanding something from the translation, but I point this code pattern issue out so that you know your trouble understanding is not just you, and not your fault.

ngOnChanges() is called when a parent component modifies (or initializes) the values bound to the input properties of a child. So if a component has no parent, the ngOnChanges() won't be invoked.

You are changing the values of the @Input properties using two-way binding, but this won't invoke ngOnChanges().

Simply concatenate all query dataframes into one large dataframe since they all share same structure, and then output to file in one call which is really the typical way to use write.table or its wrapper, write.csv:

Specifically, turn for loop:

I try to figure out your problem hope you want the following code to get output

Finally i've found the solution. There's a option for the JVM missing telling the tiki.jar to use the headless Mode.

You fiddle still contains some typo so it doesn't work.

You don't need to store the entire selected object. You can just keep the index.
