Internal Server Error after upgrading module in odoo

Question

After i clicked the upgrade option from Apps for my particular module, i was logged out and can see only the database selector page now. If I select my database, It gives me

Internal Server Error

The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.

I think there is something wrong with my last code, But have no idea where or how do i fix this and login again .Here is the traceback,

I am using Odoo 12 CE. How do i fix this?

EDIT Here is the mdoel in the module which i was trying to upgrade(Last change i made).

class proddetail(models.Model):
    _name = 'vendr.proddetail'

    name = models.Char(related='rel_product_template.name')
    numb = models.Char(string='No')
    area = models.Char(string='Area')
    production = models.Char(string='Production')
    prev_yr = models.Char(string='Previous Year')
    curr_yr = models.Char(string='Current Year')

Fixed the error after several hours of searching!. I had accidently put a whitespace in a one2many model field in another module. Strange, the error never gave a clue about that module!. — p.ry
The error messages aren't helpful all the time. Welcome to Odoo programming or i bet to programming at all ;-) Could you please add the wrong code to your question (little understandable example with both models because it's a onetomany relation)? And you can answer yourself, which will help others with similar problems. — CZoellner
@CZoellner. Ok i've updated the question and given what went wrong in the answer.thanks. — p.ry

after going through my modules a couple of hours, found that there was a single whitespace i accidently put.Removing it solved the issue!

the line with error:

samplet = fields.One2many('tests.sampletest','id ',string="Sample test details")

there is a whitespace immediately after id. The tests.sampletest is another model in the same module(not the one i was trying to update).
