Perhaps this is a Rails issue. However, I need to first determine whether
I simply am missing something about updating members of an array.
I have an array of 10 ActiveRecord objects. I wish to iterate over the
array and update an attribute. When I do this the underlying table row
changes but the object in the array frequently does not. For example:
count = 0
current_entries.each do |entry|
puts( entry.object_id )
puts( current_entries[count].object_id )
puts( "***" )
puts( entry.lock_version )
entry = set_customs_entry_status_for( entry, status )
puts( entry.lock_version )
current_entries[ count ] = entry
puts( current_entries[ count ] = entry )
end
gives:
58380880
58380880
***
0
5
5
58378260
61590300
***
0
5
5
58377460
58392560
***
. . .
immediately followed by:
current_entries.each do |entry|
puts( entry.lock_version )
end
gives:
0
5
5
5
0
0
0
0
0
0
0
0
0
Does anyone see what it is that I am doing wrong? Why are some, but not
all, of the objects in the array unchanged?

I just did not see what my data was telling me. There is a contingent update on entry when a different model is updated. This was creating the stale record issue because the table was being updated via a different set of objects from those under examination in the test. -- *** E-Mail is NOT a SECURE channel *** James B.
