I am using an SQLite database, mostly because that is what the project started with, however I am willing to move it over to a MySQL database, which I probably will in the future for the better features.
I am trying to transfer virtual relationships using the json schema upload/modify tools.
When I create a new table with the upload, and I pass in a table schema with the relationship description afterwards, the table is created but the relationships are not brought in. If I then try to modify the json schema in the dreamfactory tools, and the press save, it says I can't alter in sqlite, but if I do it using MYSQL it says:
SQLSTATE[23000]: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails (
bitnami_dreamfactory.db_virtual_relationship, CONSTRAINTdb_virtual_relationship_ref_service_id_foreignFOREIGN KEY (ref_service_id) REFERENCESservice(id) ON DELETE CASCADE) (SQL: insert intodb_virtual_relationship(type,service_id,table,field,ref_service_id,ref_table,ref_field,junction_service_id,junction_table,junction_field,junction_ref_field,ref_on_update,ref_on_delete,last_modified_date,created_date) values (has_many, 8, loans, loan_id, 10, Collateral, loan_id, , , , , , , 2017-03-02 17:19:42, 2017-03-02 17:19:42))It looks like it is trying to (in both sqlite and mysql) insert the relationships, but all I want it to do is have dreamfactory remember the virtual relationships, just like it does when i successfully create them manually. What am I supposed to do so I don't have to go through an entire list of relationships and re-create them every time I want to move to a different location for local testing?
Here is an example json schema:

and it also does not bring through the virtual relationships.
