I need to relate a field which is on a One2many field of another model, so far I've tried like this:
field_many = fields.Many2one('other.model', string="Many field")
field_related = fields.Float(string="My field", related="field_many.one2manyfield.field")
But it throws me:
Traceback (most recent call last):

Any ideas on how to achieve this?
But you are creating a related field that is in one2many field?!! don't forget o2m can have more than one record so odoo will be confused when trying to get the value.
o2m_field.some_field # witch record to access [like singleton error]
but the error is showing that odoo cannot find a field named one2manyfield in other.model is it a related field too.
if so i think odoo cannot find it because by default related field are not stored in database. but storing a related field that is one2many field is not by just adding store=True i didn't try it but as we know o2many field should have a many2one in other model.
so it's better to explain what you want by example and i think you need to use power of computed field instead.
