OpenERP classes documentation?
I am using odoo on version 8 and 12 and I'm looking for documentation with all OpenERP classes that could be used on Odoo. Everything I know about them is for some examples I found on Odoo files like "Odoo8/addons/hr/hr_view.xml". We can find the next code on that file:
<field name="image_medium" widget='image' class="oe_left oe_avatar"/>
<label for="name" class="oe_edit_only"/>
<label for="category_ids" class="oe_edit_only" groups="base.group_hr_user"/>
Exploring the odoo files I can find classes that begins with "oe_" everywhere, but I could not find documentation about it anywhere. Could you help me.
