In openerp 7 list view i want to shows the state value sort in the order draft, assigned and cancel currently shows in Asc or Desc. But in my case we need sorting in the order draft, assigned and cancel state. Based on applied in order by in python file
For example in the SQL the code:-
select state, date from object_name ORDER BY CASE WHEN state = 'draft' THEN 0 WHEN state = 'assigned' THEN 1 WHEN state = 'cancel' THEN 2 ELSE 3 END, date desc
The above sql code applied in the python
_order = "CASE WHEN state='draft' THEN 0 WHEN state = 'assigned' THEN 1 ELSE 2 END, date desc"
In the above query sorting selection value working in the pg_admin but in the python code its shows below error
Invalid "order" specified. A valid "order" specification is a comma-separated list of valid field names (optionally followed by asc/desc for the direction)
Based on this sorting order by selection value how to apply in openerp ? Override search method also applied the same sql query but shows same issue
per default you can only sort by fields but you can override this
the following code:
def _generate_order_by(self, order_spec, query): my_order = "CASE WHEN state='draft' THEN 0 WHEN state = 'assigned' THEN 1 ELSE 2 END, date desc" if order_spec: return super(sale_order, self)._generate_order_by(order_spec, query) + ", " + my_order return " order by " + my_order
to your sales_order model. I think this solves your problem. order_spec is given by the client or other order statment and add your stuff as well.
Hint: Overriding this method can add security holes like sql-injection if you do not check carefully your code and know what you do
UPDATE: I build a more generic version to update the sorting of 'state' as defined in the model instead of the name. I publish in our blog: http://blog.initos.com/2013/08/15/openerp-sortieren-nach-prozess-status/ with a german problem description but you can see the code
A version of Markus' answer from his blog. This one only changes the
state ordering if
state was in the query.
def _generate_order_by(self, order_spec, query): "correctly orders state field if state is in query" order_by = super(this_table_class, self)._generate_order_by(order_spec, query) if order_spec and 'state ' in order_spec: state_column = self._columns['state'] state_order = 'CASE ' for i, state in enumerate(state_column.selection): state_order += "WHEN %s.state='%s' THEN %i " % (self._table, state, i) state_order += 'END ' order_by = order_by.replace('"%s"."state" ' % self._table, state_order) return order_by
