Change default time range on views #154

Closed Aliefe2002 closed 5 months ago

Aliefe2002 commented 5 months ago

I have added a lot of variables and charts on a view so now it is very laggy. Default time range is 2 hours so a lot of data is received when page is loading. I want to reduce that from 2 hours to 30 min or 10 min so that my page can load easier. I have found 3 locations that promise to be the default time range however they weren't. Could you help me with that?

image this is hmi/static/pyscada/js/pyscada/pyscada_v0-7-0rc14.js. At first i thought that when page is loading, PlusTwoHours button is pressed and this button makes start of date range 2 hours ago, however this change didn't work

image this is again on the same file

image again same file and this looked most promisin however changes still didn't affect anything.

So where can i change the default time range for when page first loads? Thanks

Hello, It was an improvement planned. It should be fixed in #155.

In this PR I added a view option to set the default time delta you want (default to 2 hours). After updating to this new PyScada version (v0.8.3) you need to apply migrations and copy static files (see point 2 here)

Hi, i know you pushed an update for this, thx for that. However for people using previous versions, turns out first 2 screenshots i provided were the right place to change default time. However i was modifying the wrong file, i was modifying the file inside /home/pyscada/.venv/....../pyscada/hmi/static/pyscada/js/pyscada/pyscada_v0-7-0rc14.js.

turns out this wasnt the file served. The file i needed to modify was located at /var/www/pyscada/http/static/pyscada/js/pyscada/pyscada_v0-7-0rc14.js

For anyone who use previous version, you can change default time by changing those lines

To answer you comment, the django collectstatic command copy the static files (JavaScript, CSS...) from static directories (as /home/pyscada/.venv/....../pyscada/hmi/static/) to STATIC_ROOT (defined in settings.py as /var/www/pyscada/http/static/, see here).

So if you manually modify the /home/pyscada/.venv/....../pyscada/hmi/static/pyscada/js/pyscada/pyscada_v0-7-0rc14.js file, you can copy it to /var/www/pyscada/http/static/pyscada/js/pyscada/pyscada_v0-7-0rc14.js using the collectstatic command (see point 2 here).
