Logging from your OpenERP module

December 27, 2011 Leave a comment

I always wondered how to, in the OpenERP web client, show those informational messages in the top of the web client. Messages such as ‘PO/00001 created’. They are very informational for users.

Well… reading a presentation on the differences between OpenERP v5 and v6 I found that one of the additions was the self.log function which, as its name implies, logs a message to the audit logs (which can be accessed at Administration/Audit/Logs) and the Administration Dashboard (which can be accessed at Administration/Reporting/Dashboard/Administration Dashboard).

The function has the following syntax:

self.log(cr, uid, st.id, _(‘Statement %s is confirmed, journal items are created.’) % (st_number,))

The function returns the id of the entry created in the res_log table (or res.log business object) and takes the message to log and the context as parameters

Cheers!

Checking lead-times in OpenERP

December 23, 2011 Leave a comment

In case you need to check your suppliers’ lead-times in OpenERP, it is quite easy. You need to go to Warehouse > Reporting >  Movement Analysis. You will be able to see a view where you can filter by partner, product, location and other attributes the planned lead-time and execution lead-time. This is a great report for checking the accuracy of lead-times.

Deleted records in OpenERP

Sooner or later you will find yourself with pgAdmin (or any other query tool) querying the OpenERP database in order to pull statistical information. It happens, and it is a healthy sign of your OpenERP implementation.

Something you need to keep in mind is how OpenERP “deletes” its records. It does not physically remove them. It just marks them as deleted. And it does so with the active field in the table. This field, which happens to be a boolean field, if true indicates that the record is not deleted. Otherwise you should not take the record into account in your queries.

Cheers!

Time-outs and the openerp-web client

December 20, 2011 Leave a comment

Sometimes you need to change the time-out setting of your openerp-web client application. There might be many reasons for this, among them the need to submit long  processes or views that take minutes to retrieve the desired data. Doing this is no big deal with the GTK client, but gets tricky  when it comes to the web client since you get a time-out error message after two minutes of inactivity.

How do you solve this? It’s easy. In OpenERP v5 you need to locate the file tiny_sock.py. In that file, search for the file that reads:

self.sock.settimeout(120)

In my web client, that happens to be the line 49. Then you change the parameter of the settimeout function to the number of seconds you desire. Then restart your web client.

With OpenERP v6 is pretty much the same story, now you do not need to modify the source code. You only need to change the openerp-web.cfg configuration file. In that file, you will find the following entry in the OpenERP Server section:

openerp.server.timeout = 450

Then you have to restart your web client application.
That’s all you need to do in order to change your timeout settings in your OpenERP Web Application.

Cheers!
