Hi, 

Please add a python file in your custom module and add the following code,

class ClassName (models.AbstractModel): 
 _name = 'report.module_name.print_food_allowance_report'

    @ api.model 
    def _get_report_values ( self , docids , data = None ): 
        data = {}
        return {'data' : data}

_name = 'report.attendance_report.report_attendance_branch_template'

@api.model
def get_report_values(self, docids, data=None):
    if not data.get('form'):
        raise UserError(_("Form content is missing, this report cannot be printed."))
    return {
        'data': data.get('form'),
use this way to get the data
