Hello world Issue

[miholeus]

I run the server with command

slicer serve slicer.ini

then try to fetch some data

and get the following error

Internal Cubes error (ModelError): Aggregate 'double_amount_sum' function mismatch. Implicit function sum, explicit function: None.

Stack trace:

Just want to confirm, fresh install according to manual gives this error.

Yes, I'm facing the same issue.

Ok, I got a solution. You need to follow "Customised Installation" part of the documentation as well. That is

git clone git://github.com/DataBrewery/cubes.git
cd cubes
pip install -r requirements.txt
pip install -r requirements-optional.txt
python setup.py install

After this, you will be able to run hello_world -

cd examples/hello_world
python prepare_data.py
slicer serve slicer.ini

Running the examples:

curl "http://localhost:5000/cube/irbd_balance/aggregate"
curl "http://localhost:5000/cube/irbd_balance/aggregate?drilldown=year"
curl "http://localhost:5000/cube/irbd_balance/aggregate?drilldown=item"
curl "http://localhost:5000/cube/irbd_balance/aggregate?drilldown=item&cut=item:e"
