Django-Chartit 'source' must either be a Q

问题:

I am using Django-Chartit to create a chart.
Trying to follow this example.
my problem is that i want to use data not from a model so i tried this code

data = \
    DataPool(
       series=
        [{'options': {
           'source': [1,2,3,4,5,6,7,8,9,10]},
          'terms': [
            'month',
            'houston_temp',
            'boston_temp']}
         ])
chart = Chart(
        datasource = data,
        series_options =
          [{'options':{
              'type': 'line',
              'stacking': False},
            'terms':{
              'month': [
                'boston_temp',
                'houston_temp']
              }}],
        chart_options =
          {'title': {'text': 'Weather Data of Boston and Houston'},
           'xAxis': {'title': {'text': 'Month number'}
                     }})

and i got an error message

'source' must either be a QuerySet, Model or Manager. Got [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] of type instead.

I dont think i can create a QuerySet from a list. Any idea ?

回答1:

It looks like Django-Chartit is really meant for making charts out of models. Notice the tag line:

Create charts from your Django models effortlessly

If there is a specific reason you can't use a model, I would look into using a separate web charts tool such as Flot. It's pure JavaScript, so you would need to send your data to the client-side in order to make charts.

First of all from their docs terms must be a list or dict of valid fields on the source which must be a Model, queryset or a manager.

So what kind of data do you want to use?

UPDATE: What is this list data source exactly? If it is a list containing id's of a model you can do this to make it a queryset

MyModel.objects.filter(id__in=[3,1,2,5,77])
