Filtering courses by their start/end date¶
The parameter panel of most courses tables has two fields Period from and until. Here are some usage examples.
>>> kwargs = dict(column_names="id line weekdays_text start_date end_date")
All courses that were active already before March 2014:
>>> pv = dict(end_date=i2d(20140301))
>>> rt.show(rt.models.courses.Courses, param_values=pv, **kwargs)
