Hi
I’m using STI and want to convert one object to the other. The reason to
why I’m using STI is that I have a report and a full report. First
someone
reports something and can only enter a few fields. Then and admin can
convert this into a full report and fill out the full report. Using STI
makes it easier to handle the views, validations etc.
When converting it I just go to the edit action of a full_report, fetch
the
report and converts it into a full report using the #becomes(FullReport)
method. The issue is when I submit this form and I want to save it in
the
update action I do this:
@report = Report.find(params[:id])
@report = @report.becomes(FullReport) if @report.type.nil?
if @report.update_attributes(report_params) …
…
The thing is that it doesn’t save the type as FullReport when I do this.
Why is that? I can’t convert it, save it, reload and update it since the
validations will fail.
So, how can I convert the object and update its attributes at the same
time?
