Ensure that save on child object fails for invalid belongs_to - TAKE TWO

Reported by Ruy Asan | June 5th, 2008 @ 10:42 PM

My original patch for this was quickly reverted because of this problem with circular belongs_to associations.

I added an extra unit test to check for the specific problem described in the mailing-list post, but I was not able to duplicate the error (tests pass fine with original code).

Here's the branch

    Apparently some people actually enjoy working with diffs ;)

    • State changed from “new” to “incomplete”
    • Assigned user set to “Pratik”

    First need to reproduce the old behavior :) I'm planning to add :validate => true/false option to association definition. So we can get this in after that is done.

    Looks like => true/false is now done and already covers the meat of this ticket, although even after updating my tests with belongs to =>true I still can't get a failure.

    Patch with stubbornly passing tests attached.

    • Tag set to activerecord, edge, patch, tested

    I am not sure if this is the same thing or not, but symptoms of my problem are:

    class A belongs_to B

    a = instance of A

    b = instance of B

    create a

    create b using 'a.the_belongs_to_column.create(yadda)'!

    1. b's validation is being called

    2. the validation is failing

    3. the row is not written.

    4.! does not report an error.

    5. a's row was written

    Sorry previous tag is leftover from a web search. Tag should be ""

    Looking up the docs in it seems that there was a :validate key before that used to default to false. Example:

    belongs_to :assocation, :validate => true

    But trying to use it in rails 2.1.0 returns an invalid key error.

    It seems that the validate key was removed. Why?

    In my case i am using a create_assocation call, the parent object fails validation but the child object is saved...

    • State changed from “incomplete” to “wontfix”

    This isn't needed anymore now that we have :validate option.
