Post [Editor/ERD] FK creation Reply with quote
hello
By random clicking I discovered ERD editor. Out of curiosity I give'm a try.
I noticed 2 issues:
1. Undo of adding FK relation removed whole parent table instead of just created FK. How to replicate:
a) create table
b) add primary key
c) Press OK
d) select 1:n relationship
e) click on table twice (for source and destination of relation)
f) try to undo the operation (ctrl+z)
expectation: removing the FK
result: whole table is being removed

2. Adding foreign relation doesn't automatically adds new column for FK. How to reproduce
a) create table A with PK column named my_id
b) create table B
c) select 1:n relationship
d) click on table A then click on table B
e) relationship is added
expectation: new column (named my_id) is added to B table
result: relationship is added by there is no FK field in B table as well as no field-to-field assignment information

At the end it seems that ERD editor is in early stage of development. I'm looking forward to see it fully functional. I would really appreciate a lightweight tool dedicated for database ERD

Thank you very much for reporting the issues. I have logged both of them.
Yes, this is just a first initial version, it will be enhanced over time.

Sorry forgot to describe the solutions for both issues.

To remove a FK, double-click the link or right-click and choose Edit. In the Edit dialog, delete the FK you don't need.
To edit the column assignment, double-click the link or right-click and choose Edit. In the Edit dialog, select source and Reference columns. Click OK to save.
