Re: How is best solution for builing chars in django (in admin too)?

We've used HighCharts with chartjs. It works; it's not ideal, but we use it very extensively and it's customisable enough to use in a reasonable way. However, depending on your requirement, it's probably more advisable get your django view to return the appropriate json for a d3 front end. HTH.

WSGI question

Sorry if this isn't for here, but I've somehow got the wrong version of python running with mod_wsgi --2.7 instead of 3.4, so none of the 3.4 libraries work, like collections or datetime. Where do I look to change this? -- You received this message because you are subscribed to the Google Groups

Django modelform not saving foreignkey

I have the following code which is supposed to create a MyConfig object. However, it doesn't as the app_model is always returned as None. The idea is to choose from a select few contenttypes and then add a key, and the resulting config will trigger a bunch of services. However whenever I save the

Ignore this. Field was in excluded_fields which I thought only stopped the display of fields, but actually stops the data from that field getting into the model. On Wed, Sep 28, 2016 at 4:59 PM, Jonty Needham wrote: > I have the following code which is supposed to create a MyConfig obj

How to include related_names in a mixing for a model?
