Classes CamelCase, modules lowercase, functions, methods and lowercase

[google-appengine] Re: TypeError: has_key() takes exactly 1 argument (2 given)
Hi Neal,
djidjadji's response correctly demonstrates what the problem is: The
second argument to template.render should be a dictionary, not an
individual object. The error you're seeing is because Django is trying
to treat your TaskLog object as a dictionary. Change:
self.renderPage('templates/list.html', TaskLogs)
to:
self.renderPage('templates/list.html', {TaskLogs: TaskLogs})
The other problem is that the 'TaskLogs' object is not a list - it's a
single TaskLog object (or None, if there were no entities that matched
your query). This is because you're calling .get() on the GqlQuery
object, which returns the first match. You should probably be calling
.fetch(limit).

Hi Neal I do use templates but zpt based ones, I am not using any bits of django there are quite a few other python lightweight frameworks running on gae now. For alternatives have a look at things like pylons or repoze, however you will possibly be a bot more on your own as django is a bit of a default for gae seeing google is shipping it.

[google-appengine] Re: TypeError: has_key() takes exactly 1 argument (2 given)
Hi
Here's my guess as to what is going on
Somewhere in django has_key(key) is being called which is
traditionally a method
of a dictionary that can check if a key is in the dictionary. Modern
python code should really use key in somedict
However app engine datastore class instances have a has_key method
which doesn't take an argument, that just tells
you if a datastore key has been generated for the entity (unfortunate
choice of names I think)
So somewhere someone is checking if a key is in a datastore entity as
if it where a dictionary which won't work
Hope this helps
Rgds

def get(self):

TaskLogs= query.get();
self.renderPage('templates/list.html', TaskLogs)
Template
{%for TaskLog in TaskLogs%}
--
There are two things wrong with this python code
The second arg to renderPage must be a dictionary with key-value pairs
self.renderPage('templates/list.html', {'TaskLogs':TaskLogs})
The template for loop needs an iterable in the var TaskLogs in the
context (the dict arg of renderPage). query.get() does not return an
iterable.
self.renderPage('templates/list.html', {'TaskLogs':[TaskLogs]})
The original TaskLogs is by Django interpreted as a context and asked
for a certain dictionary key ('forloop') with has_key(key). But it is
a db.Model instance with a has_key(self,key) method.

return True
return False
But I'm still at a loss how to correct...
