How to have more than one many2one field for a method?

Question

Hello,
I have a table material_code I have fields like m_category, name, code.
I have an another table material_example I have same fields m_category, name, code.
I have to set the all the three fields as many2one which is related to the all three fields of the material_example.
But only one field can be set as many2one and it only takes "name" field from material_example.
How can I get all the three fields and relate them with?
Please help me with an example code

Hi Uppili Arivukkannu,

* code  = fields.Many2one('ModelName', string="Code")*
Step-2: in material_example model
* m_category  = fields.One2many('ModelName', ' m_category ')*
* name  = fields.One2many('ModelName', ' name ')*
* code  = fields.One2many('Mo
