qetch's Issues

Not able to load the datasets in browser

Hi Miro
When I try to load the UI ,the definition api just shows loading and data is not rendered as below.

I tried the test_connection.js and it printed todays time.So it is able to connect to qetch DB. This has connection string as postgres://myusername:@localhost/qetch and the same is getting printed inside the api call as below.
I kept console.logs inside the defintion api endpoint and its reaching the endpoint but postgres connection is not working.The connection string looks ok to me.Iam able to connect to the postgresSql from a DB visualizer and see that tables are also created successfully.

it is printing only line 154,none of the other logs are getting printed.
Can you please help me understand the issue?
TIA

Endless time series loading

I encountered an issue loading time series, I imported the time series as explained here. The dropdown menu works for me and I could see the time series list. However, any time series I chose takes forever to load and loading never ends, I waited over 3 hours for varying time series.

Am I missing something?

LICENSE missing

Great repository. But without LICENSE no one can use this code :)

What is the database schema?

Can you provide a script for creating the proper tables in the postgres database? I tried to reverse engineer the schema by reading through the import script. This got the import script to run mostly without errors, but when I run the server I don't see any data sets.

Awesome work and thanks!
