Defect #13518

Updated by Toshi MARUYAMA over 9 years ago

In Redmine version 2.2.3, when you copy a project that the issues have custom fields, this fields aren't copied.

In a previous release of Redmine (2.1.2) this problem is resolved.
*The solution* could be the same that is explained in the #11315:
issue 11315: http://www.redmine.org/issues/11315

This solution consist in:

* Modify the file app/models/issue.rb to add a call to a function to recalculate the custom fields
** In *tracker_id* function:
<pre><code class="diff">
def tracker_id=(tid)
self.tracker = nil
result = write_attribute(:tracker_id, tid)
- @custom_field_values = nil
+ recalculate_custom_field_values!
result
end
</code></pre>
** In *project* function
<pre><code class="diff">
def project=(project, keep_tracker=false)
project_was = self.project
write_attribute(:project_id, project ? project.id : nil)
association_instance_set('project', project)
if project_was && project && project_was != project
(...)
- @custom_field_values = nil
+ recalculate_custom_field_values!
end
end
</code>
</pre>

* Finally, add the new method in lib/plugins/acts_as_customizable/lib/acts_as_customizable.rb
<pre><code class="ruby">
# Recalculate custom_field_values based on current available_custom_fields.
# We need to make sure no extraneous custom_field_values are saved,
# #custom_field_values= will only save values for custom fields available
# to this object.
def recalculate_custom_field_values!
cfv_hash = custom_field_values.inject({}) {|h,cfv| h[cfv.custom_field.id] = cfv.value; h}
reset_custom_values!
self.custom_field_values = cfv_hash
end
</code></pre>
