Legacy with rails4 branch 'changed' issue

[lustremedia]

I have a legacy table with a column name changed which is reserved by ActiveRecord

ActiveRecord::DangerousAttributeError in Events#show
changed is defined by Active Record

How can I tell oracle enhanced adapter to use a different name for that column name?

Is there something like self.column_name changed, AS othername

It would also be good to have this in the legacy documentation if it exists ...

Use safe_attributes gem https://github.com/bjones/safe_attributes

Hi, #182 has been merged in v1.5.0 release which just supports Rails 4. You can have a column name changed.

Would you tell me the exact rails version?

Hi I am using Rails 4.0.0 and v1.5.0. I just upgraded to 4.0.1 and I am testing to let you know if something has changed.

Ok I still get ActiveRecord::DangerousAttributeError with changed is defined by Active Record

Rails 4.0.0 and 4.0.1
OracleAdapter ~> 1.5.0

Thanks for the update. It's my bad. #182 has nothing to do with your question, it allows to create a column named "FIELD".

I also find Rails 4.0.1 with sqlite3 as database, ActiveRecord::DangerousAttributeError generated after this migration.

$ rails g scaffold item name:string changed:string

So I can say there is no oracle-enhanced specific tips to create a table with changed columns.

As @PavelPenkov kindly commented to use safe_attributes gem to workaround this error. It looks it allows you to do so. https://github.com/bjones/safe_attributes/blob/master/spec/safe_attributes/safe_attributes_spec.rb#L10

or contact https://groups.google.com/forum/#!forum/rubyonrails-talk mailing list for wider knowledge.

Ok thanks. It looks like I can set the column to ignore in my case. So there is also no way to set an alias for a column name, sort of like an changed AS mychanged?

@PavelPenkov @yahonda safe_attributes is not supported by Rails 4 as per bjones/safe_attributes#9 so that is not going to help but I would close the issue since it is not related to oracle enhanced but rather ActiveRecord ...

Closed.
