When I create a new table the field order is always different than what I specified in the

class newClass(osv.osv):
    _columns = {
        fieldA:fields.char('Field A',size=10),
        fieldB:fields.char('Field B',size=10),
        fieldC:fields.char('Field C',size=10),
    }

Is there some way I can force the fields to be created in the new table in the order I've specified?

Why do you need the fields in a specific order? ORM persists the models you define as OpenERP see's fit - the order shouldn't matter. It is not important to the Web client, SQL or other python code since you can access them in any order.

In the academic sense, both database fields and database rows are 'sets' rather than 'ordered lists'.

If you really need to do this, define your own SQL to create the table.

You would do this by using the tag: _auto = False to tell OpenERP you will code the persistence of this model, then writing a def init(self,cr): funtion. Then you can do cr.execute and use SQL.

To answer your question, I don't like the default field order that appears in a view. Perhaps I should be asking how to order the fields in the view.

To change the order of fields in a view (and I can see why you would want to do this) you need to edit the XML definition of the view. Settings -> User Interface -> Views. You should really create your own view that inherits and modifies a base view, rather than changing it.

If you haven't created your own view for your model, OpenERP will generate one on the fly, which is why it would look messy.
