Should I be able to see the updates to the dataframe in the Global environment as they are made?.When the editable function works right, is it editing long_sepal or data?.My questions (beyond "How can this work?"):
The UI side behaves as expected, but when I edit a page and hit my Write to Table button, then reload or close out of the app, it does not look like the DT or database has updated. For number 2 a better method (if you are using an old version of SQLite3 that does not have UPDATE FROM) would be: update MyTable as dst set (vala, valb, valc) (select vala, valb, valc from MyTable where objectid dst. If you only wanted to update a single column to a static value, you could use a subquery in the update statement correctly. My plan is to use the DT and DBI packages to edit specific values, then push the updates back to the SQLite table by dropping the old one and writing the new one in its place (haven't coded the drop table yet, but will go into button actions). I have created a for an editable SQLite membership database dashboard.
