Odoo 10 KeyError when installing module

Question

I am working on Odoo 10 since a few months, I made a custom module which depends on some Odoo's modules. Today I wanted to create a user manual because my work is almost finished, so I decided to create a new data base to start from zero and be able to explain step by step how to install modules and how it works... The problem is, I get this error :

Odoo Server Error

    field = target._fields[name]
KeyError: 'workorder_id'

Now I am not sure but there seem to be a problem when Odoo should be importing my files because in the database my tables aren't created at all, so I don't know if they aren't created because of this error or if this error is because my tables aren't in the database. Anyway, I tried to comment where this workorder_id appears but it didn't change anything, the error is still there, I tried commenting one by one trying to restart the server and all but nothing changes. I have seen a lot of topics where they talk about inheritance but I don't think that is the case, workorder_id is my own field and it's used in my own models.

Here are the models where this field is used :

class ControlPart(models.Model):
    """
        Modèle pour la vue de la pièce contrôlée.
    """
    _name = 'spc.control.part'

    name                            = fields.Char(string='Piece name')
    starting_date                   = fields.Date(string='Starting date')
    ending_date                     = fields.Date(string='Ending date')
    basket_position                 = fields.Char(string='Basket position')
    piece_number                    = fields.Integer(string='Piece number')
    note                            = fields.Text(string='Notes')
#     operation_workorder_id          = fields.Many2one('spc.fabrication.order', string='Fabrication order', 
#                                                       related='operation_id.workorder_id')
#     operation_workorder_id_product_id  = fields.Many2one('product.product', string='Product code', 
#                                                      related='operation_id.workorder_id.product_id')

    operation_id        = fields.Many2one('spc.operation', ondelete='restrict', string='Operation') 
    person_id           = fields.Many2one('spc.person', ondelete='restrict', string='Operator')
    workcenter_id       = fields.Many2one('mrp.workcenter', ondelete='restrict', string='Workcenter code')
    control_measure_ids = fields.One2many('spc.control.measure', 'control_part_id', ondelete='restrict', string='Measures')

class Operation (models.Model):
    """
        Modèle pour la vue des opérations.
    """
    _name = 'spc.operation'

    name            = fields.Char(string='Operation name')
    number          = fields.Integer(string='Number')
    pcerp_number    = fields.Char(string='Pro Concept number')

    #workorder_id    = fields.Many2one('spc.fabrication.order', ondelete='restrict', string='Fabrication Order')

Thanks for your time !

EDIT : So after some time searching for the problem, with my colleague we didn't really find what was wrong. We suppose that Odoo didn't reload files when the service was restarted because we tried to put some wrong code in the files and Odoo simply ignored it. Maybe something was still in the memory and it kept using the same files, so we managed to resolve the problem finally by killing all the process. I hope this can still help.

just creating this field will not cause this error where did you use it. — Charif DZ
I used it in these models I put in the original post and in the view, I also commented it in the view but nothing changed. That's what I don't understand, I didn't use it elsewhere, I read all my models again to try to find it but it's only there in those 2 models and in my views — Isariamkia
did you comment all it's usage? and still get this error this means that you are using it may be in a model that is intalled before the installation of this model — Charif DZ

Here is how I resolved the problem, it's not a great solution but it's the only way we found :
