jasper_report with records

[Bruno Hostalery]

Is someone know how to use records with jasper_reports.

I made a xml file with my fields, create my report, make link in openerp,
put in my parser to test :

Code:
def production_labels( cr, uid, ids, data, context ):
   records = []
   for x in xrange(10):
      records.append({'numero':x,'nom': 'produit %s'%x})
   return {
# 'ids': ids,
# 'name': 'pm_mrp.production.labels',
# 'model': model,
      'records': records,
      'data_source': 'records',
# 'parameters': {'titre':'titre' },
   }

and try it, but i have this error :

Code:
  File "/opt/openerp/server/bin/addons/jasper_reports/jasper_report.py", line 96, in execute
    generator = CsvRecordDataGenerator()
TypeError: __init__() takes exactly 2 arguments (1 given)

I modify jasper_reports with
generator = CsvRecordDataGenerator(self.report)

But i have :

Code:
   File "/opt/openerp/server/bin/addons/jasper_reports/JasperReports/RecordDataGenerator.py", line 56, in generate
[2010-04-01 13:11:37,205] ERROR:web-services:[25]: for record in self.data['records']:
[2010-04-01 13:11:37,205] ERROR:web-services:[26]: AttributeError: CsvRecordDataGenerator instance has no attribute 'data'

i modify __init and jasper with :

Code:
    generator = CsvRecordDataGenerator(self.report,self.data)

   def __init__(self, report, data):
      self.report = report
      self.data = data

and i obtain :

Code:
[2010-04-01 13:13:42,994] ERROR:web-services:[22]: File "/opt/openerp/server/bin/addons/jasper_reports/jasper_report.py", line 101, in execute
[2010-04-01 13:13:42,994] ERROR:web-services:[23]: self.temporaryFiles += generator.temporaryFiles
[2010-04-01 13:13:42,995] ERROR:web-services:[24]: AttributeError: CsvRecordDataGenerator instance has no attribute 'temporaryFiles'

i modify again jasper_report.py with (line ~94)

Code:
         if self.data.get('data_source','model') == 'records':
            generator = CsvRecordDataGenerator(self.report,self.data)
            generator.generate( dataFile )
         else:
            #generator = XmlBrowseDataGenerator( self.report, self.model, self.pool, self.cr, self.uid, self.ids, self.context )
            generator = CsvBrowseDataGenerator( self.report, self.model, self.pool, self.cr, self.uid, self.ids, self.context )
            generator.generate( dataFile )
            self.temporaryFiles += generator.temporaryFiles

Summary :
modify file jasper_reports to have in execute :

  if self.report.language() == 'xpath':
   if self.data.get('data_source','model') == 'records':
    #generator = XmlRecordDataGenerator()
    generator = CsvRecordDataGenerator(self.report,self.data)
    generator.generate( dataFile )
   else:
    #generator = XmlBrowseDataGenerator( self.report, self.model, self.pool, self.cr, self.uid, self.ids, self.context )
    generator = CsvBrowseDataGenerator( self.report, self.model, self.pool, self.cr, self.uid, self.ids, self.context )
    generator.generate( dataFile )
    self.temporaryFiles += generator.temporaryFiles

and modifiy RecordDataGenerator.py to have in CsvRecordDataGenerator(AbstractDataGenerator):

 def __init__(self, report, data):
  self.report = report
  self.data = data
