ComputedCustomField plugin for Redmine

Description:

This plugin adds a new type of Custom Field named "computed". The value of computed field can be set by formula. In formula constructions like %{cf_id} are replaced by IDs of custom fields. Valid formula is a valid Ruby code executed when customized object is updated. To put a field ID in the formula, double-click on an item in the list of available fields.

Notes:

• %{cf_id} — must be an ID of existing custom field
• If format of Custom Field is Text, Long Text or List, you need to surround '%{cf_id}' with quotes
• Be careful with code in formula, if it would wrong your application can be crashed
• This plugin has been tested on Redmine v2.6.7 with RoR v3.2.22 and Redmine v3.1 with RoR v4.2.3
• There are six types of output format: "int", "float", "string", "link", "datetime", "bool", "percentage"

Installation:

Clone from GitHub

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.

Examples:

%{cf_1}*2+%{cf_2} 
# means 
# custom_field_value(1) * 2 + custom_field_value(2)

(%{cf_1}/3.14).round(2)

if %{cf_1}.zero?
 %{cf_2}/2
else
 %{cf_3}/2
end

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

# For ProjectCustomField 
self.parent_id == 2

# If format of Custom Field with ID 4 is Text, Long Text or List
'%{cf_4}'

# 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"

# If format of Custom Field is Link, and you need to set up a specific link caption
"'Click here for more details':/projects/#{project.try(:identifier)}/wiki"
