I'm relatively new to Hobo, working with a relatively mature app ( > 1
year) in Hobo 1.3.
The feature I'm adding requires me to add data to the join table of a
many-to-many relationship. Specifically, GraphPanes >=< DataSets. To track
whether a DataSet should appear in the GraphPane's legend, the join table
(DataSetGraphPanes) now has a boolean in_legend field. This was easy enough.
Showing the relationship in the GraphPane show view was also manageable by
changing the view hint from `children :data_sets` to `children
:data_set_graph_panes` and tinkering with the card for DataSetGraphPanes a
bit.
However, the form for adding these relationships is a puzzle for me. The
existing form for a GraphPane adds a DataSet directly:
<select-many:data_sets
options="&DataSet.activity_is(activity_for(@this))" />
...but what I need now appears to be a sort of sub-form for a
DataSetGraphPane which has that same select menu of DataSets, but shows an
items list of DataSetGraphPanes, with a checkbox to set the in_legend
boolean for them, and that sort of tag appears to require some contortions
in DryML.
What have I gotten myself into?
