[openerp] ZipImportError: bad local file header in pathtozipfile.zip

Bismillahirrahmaanirrahiim...

Today I just learned how to create a simple module in openerp...

I read this sources:

1. http://www.ibcscorp.com/application-integration-customization/erp/openerp-2/openerp-custom-module-development-quick-start-guide/
2. http://imsciences.edu.pk/serg/2010/09/openerp-module-development-part-1/

There are some different method from that two sources:

1. The first source using file named __openerp__.py as module descriptor file, but the 2nd source using file named __terp__.py
   I don't why they using different file name... I will find out later
2. the first source says that we should zip folder as modulename.zip then instal to openerp through menu administration/import module,
   but the 2nd source says that we just put the folder into folder openerpserver/addons but dont know the next procedure

So, I have try the first source and it was install successfully..

then I tried the 2nd source but with 1st source method to install the module.

1. Zip the module
2. Go to menu administration/modules/import module
3. attach the zip file
4. go to menu modules
5. search module name I created
6. click schedule for installation
7. apply schedule upgrades

but it raises error such these:

openerp ZipImportError: bad local file header in pathtofile.zip

I search in google and founf this answer (http://www.openerp.com/forum/topic15598.html)

in server, unzip student_info.zip in addons/student_info (but warning, you do not have addons/student_info/student_info)
in client go to administration->modules, update list of modules, install your module.
If you use dia to build your modules, or generally, unzip it in addons before, and update list of modules.

SO, the solution is:

1. cancelling the installation of module
2. unzip the modulename.zip in openerpserver/addons/
3. remove modulname.zip file
4. click menu administration/modules/update modules list
5. search for my modulname
6. schedule for installation
7. apply schedule upgrades

then I can see the real error,

I fix it directly in openerpserver/addons/modulename

then I click apply schedule upgrades until success information appear

btw, the 2nd source will make you dizzy

because we will found some error when implemented that...

it just because different text fonts when you use quotes and double quotes

and there a line missing in sim.py

which is:

from osv import osv, fields

in first line

Hope this help
