ComputedCustomField plugin for Redmine

Description:

This plugin provides a possibility to create a computed custom field. The value of the computed field can be set by formula. In formula constructions like cfs[cf_id] are replaced by IDs of custom fields. A valid formula is a valid Ruby code executed when a customized object is updated. To put a field ID in the formula, double-click on an item in the list of available fields.

Changelog:

Plugin's changelog is available here.

Important information

This is a new version of the plugin. Since version 1.0.0 it is not compatible with previous versions. The following constructions in formula %{cf_id} are no longer supported. Instead use cfs[cf_id]. If you need to upgrade from older versions, please check out migration section.

Notes:

• cfs[cf_id] — must be an ID of existing custom field.
• Be careful with code in a formula, if it would wrong your application can be crashed.
• If a computed custom field was created after creating of a customized object you need to re-save an object to evaluate computations.
• After updating of formula customized objects should be re-saved.

Installation:

Clone from GitHub

# Latest version
git clone https://github.com/annikoff/redmine_plugin_computed_custom_field.git computed_custom_field

Or download ZIP-archive and extract it into "computed_custom_field" directory.

Run migrations

rake redmine:plugins:migrate

Migration:

• Navigate to plugin folder.
• Run git pull
• Run rake redmine:plugins:migrate
• In computed CF's formulas replace %{cf_id} constructions by cfs[cf_id].

Compatibility

The plugins supports the following Redmine versions: 4.0.x, 3.4.x, 3.3.x, 3.2.x, 3.1.x, 3.0.x, 2.6.x, 2.5.x.

Examples:

cfs[1]*2+cfs[2]
# means
# custom_field_value(1) * 2 + custom_field_value(2)

(cfs[1]/3.14).round(2)

if cfs[1].zero?
 cfs[2]/2
else
 cfs[3]/2
end

# For IssueCustomField
(self.estimated_hours || 0) * 2

# For ProjectCustomField
self.parent_id == 2

# If format of Custom Field is Link
"/projects/#{self.project_id.to_s}/issues/new?issue[subject]=Review+request+[##{self.id.to_s} #{self.subject}]&issue[tracker_id]=3"

# Retrieve a value from Key/value list custom field
cfs[1].try(:id)
