Hello, 

This is my function: 

@api.depends('xidentification')
    def _concat_nit(self):

        # Executing only for Document Type 31 (NIT)
        if self.doctype is 31: # <--------------- THIS IS LINE 147
            # First check if entered value is valid
            self._check_ident()
            self._check_ident_num()
            # Instead of showing "False" we put en empty string
            if self.xidentification is False:
                self.xidentification = ''
            self.formatedNit = ''
            # Formatting the NIT: xx.xxx.xxx-x
            s = str(self.xidentification)[::-1]
            newnit = '.'.join(s[i:i+3] for i in range(0, len(s), 3))
            newnit = newnit[::-1]
            nitList = [
                newnit,
                # Calling the NIT Function which creates the Verification Code:
                self._check_dv(str(self.xidentification))
            ]
            formatedNitList = []
            for item in nitList:
                if item is not '':
                    formatedNitList.append(item)
                    self.formatedNit = '-' .join(formatedNitList)
            # Saving Verification digit in a proper field
            self.dv = nitList[1]


But I get the following error: 

File "/home/travis/build/OCA/l10n-colombia/l10n_co_res_partner/models/l10n_co_res_partner.py", line 147, in _concat_nit
if self.doctype is 31:
File "/home/travis/odoo-9.0/openerp/fields.py", line 819, in __get__
record.ensure_one()
File "/home/travis/odoo-9.0/openerp/models.py", line 5403, in ensure_one
raise ValueError("Expected singleton: %s" % self)

ValueError: Expected singleton: res.partner(3, 7, 17, 32, 22, 21, 6, 18, 16, 14, 19, 20, 13, 11, 29, 35, 28, 8, 23, 24, 34, 25, 9, 26, 27, 39, 38, 15, 33, 37, 43, 5, 4, 42, 10, 30, 31, 12, 36, 1, 40, 41)

I have no clue why I get this error? Actually the function works in the interface, but Travis is complaining: https://travis-ci.org/OCA/l10n-colombia/jobs/139356438#L645

Any Ideas on how to fix this issue?

Hi,

Try giving @api.one decorator for the method. 

@api.depends('xidentification')   
@api.one    
     def _concat_nit(self):


This decorator loops automatically on Records of RecordSet for you. Self is redefined as current record:

Or

try iterating with for loop 

     for record in self:

        if record.doctype is 31: # <--------------- THIS IS LINE 147 
             # First check if entered value is valid            
            record._check_ident()


Hopes this solves the problem.

Thanks for your answer. Yes, with api.one it works, BUT api.one is deprecated in Odoo9, so I don't want to use it. Any other ideas? 

Checking other resources I see that it might be an issue with a loop?

Dominiac,

here in _concat_init you are getting list of res.partner object and when you are trying to access doctype off it, its not able to perform that as it is "list of objects".

So what you can do is,

1) As suggested by Baiju,

2) loop through self and check for each record as:

@api.depends('xidentification')    
    def _concat_nit(self):
         for record in self:
             if record.doctype is 31:
                 # Further code goes here, use record instead of self......


Hope this will help you...
