I've renamed a column in an activerecord table by migrating. I
searched and changed all references from <old column name> to <new
column name> in source / tests.
However, a lot of my tests now fail with errors of the type :
SQLException ... table has no column named <old column name>.
I also did a grep and can't find any references to <old column name>
in the project directory.
Which files could be using the <old column name> ? Are there some
binary files that I need to clear ? I'm using Rails 3.
If the test database was still the old format then I would have
expected the error when running the tests to be of the form
SQLException ... table has no column named <new column name>
rather than no column <old column name>
@OP if your original post was incorrect and the error *is* saying that
there is no column <new name> then I think djangst is probably
correct. If your original post is correct then you must be
referencing the old column name somewhere. Have a look in test.log
and see if that gives any clues.
