I have developed one qweb report with barcode .I have tested it on four different system and it works perfectly ,but on client's server it gives following error during report printing

see the fragment from your error log in the question post above:

File "/home/ols1/extra_addons/product_barcode_qweb/report/product_barcode_print.py", line 62, in _generateBarcode
 Code128().getImage(barcode_string, path="./").save(fp, "PNG")

here you try to save file to current directory, but you do not have necessary permissions on the current directory. I suggest following changes in product_barcode_print.py:

import os

from openerp.tools import config

my_data_directory = os.path.join(config['data_dir'], "custom_filestore", "your_module_name")

if not os.path.exists(my_data_directory):
    os.makedirs(my_data_directory)

then, in the code at line 62: Code128().getImage(barcode_string, path="./").save(fp, "PNG") -Use my_data_directory instead of "./" -local directory:

Code128().getImage(barcode_string, path=my_data_directory ).save(fp, "PNG")

also adapt the rest of code to accordingly use my_data_directory instead of local directory to read from and write to file(s) you create in your module. that's it, after this change you save files to directory where you have all necessary permissions.

NOTE:

Above changes should be enough in your case, but, in the best case you should append database name to data_directory path, so you'll have separated directory for each database in a multidatabase environment. in v8 it may be implemented as:

@api.model
def get_custom_data_dir(self):
 return os.path.join(config['data_dir'], "custom_filestore", "module_name", self.env.cr.dbname)

optionally you can use this approach, if it's necessary.

This is pretty simple @bhavik you don't have required permission on file.
