There seems to be a bug when trying to use mixins and PSP...
For example...
I have some layout classes... BaseLayout, which overwrites writeHTML... it
calls preLayout, writes some VERY basic html.. calls writeHTMLBody, then
calls postLayout.
SiteLayout overwrites writeHTMLBody ... which prints a bunch of layout html
(tables and etc) and calls writeScreen
I then have a security mixin called SecureMixIn... which has the method
preLayout()
Now.. using these classes.. the following works:
from layout.SiteLayout import SiteLayout
from screen.SecureMixIn import SecureMixIn
class test2(SecureMixIn, SiteLayout):
def writeScreen(self):
self.writeln("Test")
Where the preLayout method from SecureMixIn overwrites the one from
SiteLayout... but the rest of SiteLayout gets used as expected. Now this page
requires someone to be authenticated from just using the mixin.
However.. the following PSP page does not work:
<%@ page method = "writeScreen" %>
<%@ page imports = "layout:SiteLayout:SiteLayout,
screen:SecureMixIn:SecureMixIn" %>
<%@ page extends = "SecureMixIn, SiteLayout" %>
<%@ page indentType="braces" %>
<psp:method name="title">return "Test page"</psp:method>
Great! We are authorized!
which gives the following error:
AttributeError: class SecureMixIn has no attribute 'awake'
Although I code add code to the PSP page to do the security check... thats
kindof beond the point. The idea is to have as little code as possible in my
psp page... and allow different functionality to be added through mixins.
Security for example.
Attached are most of the files involved.
Of course... the SecureMixIn attached does not include code to handle my
security... I am currently using a layout that extends SiteLayout to add
security..... But using the mixin would be much prefered....
