My .py file is

class orion_specific_product(models.Model):
    _name = 'orion.specific.product'
    
    name = fields.Char(required=True)
    mfd_pro = fields.Boolean(default=False)
    active = fields.Boolean(default=True)
    sale_ok = fields.Boolean(default=True)
    product_id = fields.Many2one('orion.product.product')
    attribute_id = fields.Many2one('temp.orion.product.attribute')
    attribute_value_id = fields.Many2one('temp.orion.product.attribute.value')
    
    @api.onchange('mfd_pro')
    def _change_mfd_pro(self):
        if self.name:
            if self.mfd_pro == False:
                if len(self.name)>2:
                    self.name = self.name[1:]
            elif self.mfd_pro == True:
                if len(self.name)>2:
                    self.name='N'+self.name
                    self.mfd_pro = True
    
    @api.onchange('product_id')
    def _change_product(self):
        if (self.product_id):
            # storing short name in name field
            pro_name = self.product_id.name
            try:
                index_value = pro_name.index(' -')
                self.name = pro_name[:index_value]
            except ValueError:
                self.name = pro_name
        #clearing temp table
        self.env.cr.execute("delete from temp_orion_product_attribute")
        #populating data to temp tables
        #1. Attributes
        self.env.cr.execute("""select a.id,a.name from orion_product_attribute a, orion_product_line l where l.att_ids = a.id and l.pro_ids = %s""" %(self.product_id.id))
        rows = self.env.cr.fetchall()
        if rows.count>0:
            for row in rows:
                self.env.cr.execute("""insert into temp_orion_product_attribute(name,a_id) values('%s','%s')""" %(row[1],row[0]))
    
    @api.onchange('attribute_id')
    def _change_attribute(self):
        if (self.attribute_id):
            #populating data to temp tables
            self.env.cr.execute("""select id from orion_product_line where pro_ids = %s and att_ids = %s""" %(self.product_id.id, self.attribute_id.id))
            row = self.env.cr.fetchone()
            if row:
                self.env.cr.execute("""select v.id,v.name from orion_product_attribute_value v, orion_product_orion_pro_value_rel r where r.line_ids = %s and r.value_ids = v.id""" %(row[0]))

                    self.env.cr.execute("""delete from temp_orion_product_attribute where a_id='%s'""" %(self.attribute_id.a_id))

I formatted your code. Make sure the indents I put are correct. In the future, to paste code, just type enter a few times, open your HTML inspector, pick an empty

element, modify it, paste your code and wrap it with

, then hit save.

wrap it with pre tags (damn !)

Hi,

Something wrong the logic & indentation of this part:

    @api.onchange('mfd_pro')
    def _change_mfd_pro(self):
        if self.name:
            if self.mfd_pro == False:
                if len(self.name)>2:
                    self.name = self.name[1:]
                elif self.mfd_pro == True:
                    if len(self.name)>2:
                        self.name='N'+self.name
                        self.mfd_pro = True

I don't know exactly what you are trying to do. Please check n correct it.

@Akhil P Sivan

All my indentation are correct

And as per logic i will expain to you:

@api.onchange('mfd_pro')
    def _change_mfd_pro(self):
        if self.name: #checks if name field has value or not
            if self.mfd_pro == False: # checks if the boolean field is false or not
                if len(self.name)>2: # checks the length of characters in the name field 
                    self.name = self.name[1:] # removes the first character
            elif self.mfd_pro == True: # if boolean field is true
                if len(self.name)>2: checks the length and then add 'N' to the start of the value in the name field
                    self.name='N'+self.name
                    self.mfd_pro = True

When does the error occurs exactly ? What action are you doing that throw the error ?
