IS THERE ANY WAY TO CONSUME THE ARGUMENTS IN __before__ OR VIA SOME
OTHER OVERRIDE?
Sample nested URL: .../CONTROL1/arg1/CONTROL2/arg2
In the overridden __before__ routine, I added the lines that the
default __before__ in CrudRestController does:
def __before__(self, *args, *kw):
tmpl_context.menu_items = self.menu_items
tmpl_context.title = self.title
... split the url ...
self.parent_arg = arg1
With the above changes, the menu_items is None and avoids the
exception in the template rendering.
However, the post_delete() function in CrudRestController still gets
all the original arguments and tries to delete the wrong record, since
the *args passed to __before__ is a tuple and cannot be consumed by
__before__ and the underlying model (for CONTROL2) has just 1 primary
key v.i.z. arg2. I.E. pks = [id] but args = (arg1, CONTROL2, arg2)
and it tries to use arg1 as the primary key to CONTROL2 and fails.
@expose() #CrudRestController source code
def post_delete(self, *args, **kw):
"""This is the code that actually deletes the record"""
pks = self.provider.get_primary_fields(self.model)
d = {}
for i, arg in enumerate(args):
d[pks[i]] = arg
self.provider.delete(self.model, d)
redirect('./' + '../' * (len(pks) - 1))
IS THERE ANY WAY TO CONSUME THE ARGUMENTS IN __before__ OR VIA SOME
OTHER OVERRIDE?
Thanks.
