Bug > attribute_changed? flag is not correctly set when modifying the array

[saurabhnanda]

Here's how to reproduce this bug:

> ar_object.some_pg_array.push(1)
> ar_object.some_pg_array_changed?
=> false

> ar_object.some_pg_array = [1, 2, 3]
> ar_object.some_pg_array_changed?
=> true

could you say your version of ActiveRecord ?

[saurabhnanda]

3.1.1

[saurabhnanda]

Were you able to reproduce this?

[funny-falcon]

I believe you :)
Unfortunately, it not easy to fix, cause it will be necessary to always save an array's copy somewere (and I really do not like to save a copy on every fetch, even you will not change array).

I really suggest you to use ar_object.some_pg_array = [1, 2, 3] syntax.

In the reality I should freeze fetched arrays, so that ar_object.some_pg_array.push(1) raise error. I regret I hadn't do it at the very beginning. And now I could not do it cause many people use this gem :(

Why don't you put a warning/deprecation notice on some_pg_array.push and see how many people write back?

In future you can freeze the PG arrays then?

Overwrite Array? Or fetch arrays as Array's subclass instances?

Fetch PG arrays as PGArray < Array probably?
