Beta of V4.5.0 available

[Tom Keffer]

Several interesting new features. Most notably, you can add, remove, or rename columns in the main database with the utility wee_database. No need to use --reconfigure with all the database shuffling involved! For example, to remove the type soilMoist2:

wee_database --drop-columns=soilMoist2

If you use this feature, remember that this is a beta release. Be sure to do a backup first!!

There is also support for using series in the templates, including generating JSON. For example, a JSON series of the maximum temperature for each day of the month would be:

$month.outTemp.series(aggregate_type='max', aggregate_interval='day').json

This generates something like:

[[1614585600, 1614672000, 58.2], [1614672000, 1614758400, 55.8], [1614758400, 1614844800, 59.6], ... ]

This is a series of 3-way tuples, where each tuple consists of the start time of the day, stop time of the day, and (in this case) maximum temperature for the day.

See the Wiki article Tags for series for more details. Please note: this is still experimental, and subject to change!

Lots of miscellaneous bug fixes. 

Find it in the usual place for development releases. 

Feedback is very welcome!!

All is well in my environment...  Running for 68+ hours.

I haven't exercised any of the "new features" or functionality.

Am looking forward to v4.5 final release.

Thanks!

Hoping to see Seasons skin with Highcharts support out of the box with new json support. Something that I would love - in fact seeing how I can do it myself..

[Karen K]

The original graphs engine with that day-night-background-coloring is nice, too.

[Praveen Chandrasekaran]

Was seeing if I can embark on project to convert Seasons charts to json based interactive highcharts. But way out of my depth.

[Tom Keffer]

I've been able to "sort of" confirm this. I say "sort of," because it works if I run wee_config directly, but not if it is run indirectly through setup.py. 

I'll figure it out.

Pasi,

Could you try again, making one small change? In setup.py, change this

    proc = subprocess.Popen(args,
                            env={'PYTHONPATH': install_lib},
                            stdin=sys.stdin,
                            stdout=sys.stdout,
                            stderr=sys.stderr)

to this

    os.environ['PYTHONPATH'] = install_lib

    proc = subprocess.Popen(args,
                            # env={'PYTHONPATH': install_lib},
                            stdin=sys.stdin,
                            stdout=sys.stdout,
                            stderr=sys.stderr)

In summary, you are adding one line, and commenting out one line.

Then give it another try.

If you are not comfortable doing this, we'll figure out another solution.

I went for pure ascii name for my setup, I'll try this with another install on the weekend.  Not sure anymore if it worked with 4.4.0 either.

[Tom Keffer]

It probably did not work on V4.4.0, but it's only a problem when doing a new installation. Using wee_config directly (as opposed to through setup.py) works as it should.

You can get the modified version of setup.py here.

Hi,

yeah, I can confirm, clean ubuntu 18.04.5 install on a x86_64 virtual machine fails with 4.5.1  install, but works fine with this modified version!  Thanks!
