This module aims to add a color picker to Odoo.
+It’s a jsColor lib integration.
+The picker allow the user to quickly select a color on edit mode
+
Note
+Notice how html code and the background color is updating when selecting a color.
+Display the color on form view when you are not editing it
+
Display the color on list view to quickly find what’s wrong!
+
Table of contents
+You need to declare a char field:
++color = fields.Char( + string="Color", + help="Choose your color" +) ++
In the view declaration, put widget=’color’ attribute in the field tag:
++... +<field name="arch" type="xml"> + <tree string="View name"> + ... + <field name="color" widget="color"/> + ... + </tree> +</field> +... +<field name="arch" type="xml"> + <form string="View name"> + ... + <field name="color" widget="color"/> + ... + </form> +</field> +... ++
Widget Options:
+
+- readonly_mode
+ - 'default' > Color Box + text
+ - 'color' > Only Color Box
+ - 'text' > Only Text
+...
+<field name="arch" type="xml">
+ <tree string="View name">
+ ...
+ <field name="color" widget="color" options="{'readonly_mode': 'color'}"/>
+ ...
+ </tree>
+</field>
+...
