I had the same 'problem' with an older pyramid version. To pass additional
configuration values to view code I came to a similar solution like the one
described by Mike.
For class based views I used dynamic type generation to store specific
values as class attributes which is then used as view code. Its easy to
serialize and load the values
e.g from a json file.
def view_class(values, cls):
newcls = type("_extended_"+cls.__name__, (cls,), {})
newcls.__values__ = values
return newcls
def MyView:
# view code
# ....
ViewCls = view_class(dict(title="Title"), MyView)
config.add_view(view=ViewCls, ...)
Arndt.
I had an idea about this. When you want to associate data with a
> callable you can use a partial function. For instance:
>
> # views.py
> def my_view(title, request):
> ....
>
> # __init__.py
> import functools
> title = "My Title"
> view1 = functools.partial(my_view, title)
> config.add_view(view1, ...)
>
> Or you could write a wrapper for view_config that does this.
>
> I've never needed additional view data like this because my titles are
> in my templates or in my view code. (I have a Mako site template with
> a 'page_title' function which I override in the individual templates.)
> But if you can't specify the title in either of those places or in the
> context, then I'd use a partial function like this.

>
> class MyClass:
> def __init__(self, title):
> self.title = title
> def __call__(self, request):
> # Use self.title.
