Avoid SQL errors when adding a project custom field as a time report criteria
|Assignee:||Go MAEDA||% Done:|
Custom fields can have different visibilities, depending on the custom field type and the current user:
- Custom fields are always visible to admins
- They are not visible for anonymous unless explicitly checked
- They are visible if the visible flag is checked (or the user in in a checked group for issue custom fields)
Now, to confirm whether a custom field is visible in a certain project, we use
CustomField#visibility_by_project_condition. Given the following conditions:
- We are a non-admin user
- We defined a ProjectCustomField of type List which is not visible
Now, when we show a time entry report and select the ProjectCustomField as an aggregation criteria, we get an error because of invalid SQL:
ActiveRecord::StatementInvalid: Mysql2::Error: Unknown column 'projects.project_id' in 'IN/ALL/ANY subquery': SELECT Sum(`time_entries`.`hours`) AS sum_hours, Coalesce(cf_9.value, '') AS coalesce_cf_9_value, `time_entries`.`tyear` AS time_entries_tyear, `time_entries`.`tmonth` AS time_entries_tmonth, `time_entries`.`tweek` AS time_entries_tweek, `time_entries`.`spent_on` AS time_entries_spent_on FROM `time_entries` INNER JOIN `projects` ON `projects`.`id` = `time_entries`.`project_id` LEFT OUTER JOIN `enumerations` ON `enumerations`.`id` = `time_entries`.`activity_id` AND `enumerations`.`type` IN ( 'TimeEntryActivity' ) LEFT OUTER JOIN `issues` ON `issues`.`id` = `time_entries`.`issue_id` LEFT OUTER JOIN custom_values cf_9 ON cf_9.customized_type = 'Project' AND cf_9.customized_id = projects.id AND cf_9.custom_field_id = 9 AND ( projects.project_id IN (SELECT DISTINCT m.project_id FROM members m INNER JOIN member_roles mr ON mr.member_id = m.id INNER JOIN custom_fields_roles cfr ON cfr.role_id = mr.role_id WHERE m.user_id = 3 AND cfr.custom_field_id = 9 ) ) AND cf_9.value <> '' AND cf_9.id = (SELECT Max(cf_9_2.id) FROM custom_values cf_9_2 WHERE cf_9_2.customized_type = cf_9.customized_type AND cf_9_2.customized_id = cf_9.customized_id AND cf_9_2.custom_field_id = cf_9.custom_field_id) WHERE (( ( projects.status <> 9 AND projects.id IN ( 1, 2, 3, 5, 12, 14, 15, 19, 25 ) ) AND ( projects.id IN ( 1, 2, 4, 5 ) ) )) AND (( time_entries.spent_on IS NOT NULL )) GROUP BY Coalesce(cf_9.value, ''), `time_entries`.`tyear`, `time_entries`.`tmonth`, `time_entries`.`tweek`, `time_entries`.`spent_on`The reason for that is the SQL generated by the
CustomField#visibility_by_project_conditionmethod called for
Redmine::FieldFormat::Base#join_for_order_statementHere, we are using the final
elsecase and attempt to use the
project_idfield on the
The correct column here would however simply be
id instead of
project_id. The attached patch fixes this behavior and avoids the SQL error. Unfortunately, I'm not really sure how to properly test this. This whole area seems to be not well tested currently...
#3 Updated by Holger Just 7 months ago
i just updated the patch to include a test for this behavior.
While the symptom described here doesn't occur that way after #29162 was applied, the underlying issue still stands. This patch thus fixes the behavior of the
ProjectCustomField#visibility_by_project_condition method. Without the applied model fix, the test fails with the described SQL error.
