This required some big overhauls. The view model no longer takes records. It only takes the date that it is responsible for, and it will ask the database for records pertaining to that date. This means that once the view model has saved all of its records, it can simply reload those records from the database. This has the effect that as soon as the user moves from DayEdit back to DayDetail, all of the interesting information has been repopulated.
These structures handle parsing and rendering of a Duration and a Distance, allowing that knowledge to be centralized and reused. Then I'm using those structures in a variety of places in order to ensure that the information gets rendered consistently.
This sets up a bunch of callbacks. We're starting to get into Callback Hell, where there are things that need knowledge that I really don't want them to have.
However, edit fields for TimeDistanceEdit now propogate data back into the view model, which is then able to save the results.
This adds the code to show the new records in the UI, plus it adds them to the view model. Some of the representation changed in order to facilitate linking UI elements to particular records. There are now some buttons to create workouts of various types, clicking on a button adds a new row to the UI, and it also adds a new record to the view model. Saving the view model writes the records to the database.
This simplifies, though not as much as I was hoping, the patterns for accessing data along strict type patterns. I may see better results once I'm getting the Time/Distance views working.
Step and weight records may be presented in any order. Any test that
tries to enforce that one gets presented before teh other can't cannot
succeed. So, I've removed that test and instead put in a warning that
will appear when the view model gets loaded.
DayDetailViewModel needs testing. I've worked out an improved API, and a set of tests to go along with it, and those can be made more easily with a mockable RecordProvider. So, in addition to stubbing out a bunch of tests, I've also created RecordProvider, mocked it, and implemented it for App.
This is preparatory work. Having the view model directly retrieve data both adds a degree of symmetry (it both gets data from and sends data to the app) and makes it possible for the view model to refresh itself when needing to revert data or after saving data.
I've created the view model and added a getter function for the weight.
I'm passing the view model now to the DayDetailView, DayDetail, and
DayEdit.
I'm starting to set up the Save function for the view model, draining
all of the updated records and saving them.
None of the components yet save any updates to the view model, so
updated_records is always going to be empty until I figure that out.
