Build a dynamic filtering form with Django // 6 - Filtering by date and view count

[@OxMiroslav]

That's awesome video! I am learning Django for more than a year and still I found something new in this channel. In this vid I found out I can use "cascaded" filter on ORM object - I can filter the object again and again.

You saved my college assignment and mental health thank you!!

[@gregruiz921]

Hey man... thanks for all you do, and keep up the great work! Much appreciated!!!

[@drewanderson5867]

really good django tutorial

[@ab5comau]

Thank you very much for this series. I have just about come to terms with Django and could not find how to handle dynamic filters.

[@ax3le-2.0]

Thank you very much for this tutorial. Please how do you refresh back to the original site when you filter

[@Jane-eunku]

훌륭한 강의입니다! Great Tutorial!

Awesome video!!

[@alizeeboussac4087]

Hi ! Awesome video thank you. Do you think it's possible to do the same thing with tables ?

[@sudipgupta87]

Nice! By querying all and then filtering, are fetching too much? or are we querying multiple times?

[@DanielLeachTen]

You are a godsend

[@TheDarrenJones]

Great video again. One question - how do you do the 'entering two lines at once' editing in VSCode? I can't even think of what to search for to find out how to do it.

[@mattfreire]

On Mac you place the cursor and then hold the option key while clicking to place the cursor in the next place. On Windows I think it would be the alt key

[@michakwiatek5031]

On linux it's Alt + left mouse or Ctr + Shift + arrow(up/down)

[@skelaw]

Great job! How can I support you?

[@malikrumi1206]

Thank you for this series. But I am curious: why didn’t you use DateTimeRangeField and or IntegerRangeField?

[@eesakamaldien1917]

Hi can this be used off model methods aswell?

[@thales-maciel]

how can I pass the values back to the template so the user can see which filters are applied?

[@cudanakiju0]

up

[@whonayem01]

Thanks!

[@anoopkg8681]

awesome

[@jlpeyret]

Wait, am I correct in thinking the mechanism here is to fetch all the table’s rows into memory and then filtering that down to only what you want? No problem if it’s a small table but not very viable if it had millions of rows. I suppose you could compose Django Q objects into a tuple and then ‘Journal.objects.get(*tuple_q)‘ so most of the code would still apply.

[@mattfreire]

There is nothing being stored in memory. This explains how querysets are evaluated: docs.djangoproject.com/en/2.2/ref/models/querysets/#when-querysets-are-evaluated

AWESOME.

Hi while using the Date Filter, it does not work and in the terminal I get an error saying : RuntimeWarning: DateTimeField TwitterL4.trend_start_time received a naive datetime (2019-05-14 00:00:00) while time zone support is active. How to resolve this

[@malikrumi1206]

Hey, it's like 9 months later, so I don't know if you still need an answer or not, but basically there are two kinds of time: 'naive', and 'timezone'. So timezone should be obvious, and naive is a time without time zone information. In your settings you are using timezone (it might just say 'tz') but the code is time naive, which is why you got this error. Look up time and time zone in the Django docs for more info.

GREAT

[@WattsInnovation]
