#1405 confirmed

Deleting parent fails after deleting all children. (unless a .reload is done on parent)

Reported by dev2 | September 10th, 2010 @ 10:04 AM

This ticket is being submitted at the request of dkubb on freenode/datamapper.

The issue is with deleting a record that has child records. Even after deleting all of the parents records in the join table the destroy still fails. I was able to work around this (under the advice of dkubb) by adding a .reload before finally destroying the parent.

In the mysql console I can see the constraings on the join table. From the console I am able to successfully delete the child records and then the parent.

@doc = Document.get(1)
Document.transaction do
  #this is a simple app, only 2 models and one Resource/model
  #the following executes successfully
  unless @doc.document_tags.destroy
    raise 'document tags failed to be destroyed'

  #the following fails unless its changed to @doc.reload.destroy
  unless @doc.destroy
    raise 'document destroy failed'
rescue StandardError => e
  puts e
