As the tutorial, if i add new fields to data model, Sugar ORM will create columns to table automatically, but its not, after added new fields, the app is crash cause table has no columns name like i have updated to model.
Can any one give me an advices?
Do I have to make a migration?
I'm new to SugarORM and I just have one question.
Does sugar automatically do rever foreign key lookups?
What I mean by that is, say I have Class A, and Class B, which has an atribute from the type A;
Can I through my Class A Object get the set who is referencing me without an extra query?
Don't know if you who is reading this has ever user Django, but the Django ORM does that and in this case through A object, using "a.b_set.all()" it would return me a list of all B objects who reference A;
Sorry for the long question.
How do I go about deleting a table if I don’t know its id?
The problem is that I am using Sugar ORM to store task for a todo list populated into recycler view. If I want to delete one of the tasks, I don’t know how to get the id for that particular task. I think it has something to do with viewHolder, but I have no idea what to do here, any help will be appreciated.
