Orderby

[Pynthon]

Hello

I searched in the book but I can't find it. Im creating a blog with
the small knowledge I have about W2P. Just for fun and to learn. I
want to order it like this:

3
2
1

and not

1
2
3

The latest posts ion the head :P. How can I do this?

Thanks,
Pynthon

Hi.

I'm assuming you have some query from where you take the posts.
In the select part there's a parameter orderby. To give it to sort it in
reverse order just write the sign ~ in front of the orderby parameter.
example
db(some_query).select(db.table.ALL, orderby = ~db.table.field)

Thanks man! Works perfect! Maybe I want this blog for my public site.
But I also want to make an admin panel. How need I to make that? I
know how to work with sessions. But can it also be safe?

Hi.

You can do something with the auth class.
Here some tutorial about it.
http://mdp.cti.depaul.edu/examples/default/tools

You can expose only functions for login/logout. Create a user by hand, through
web2py admin.
Then create controllers/functions that requires authorization.

For the safety... it should be enough safe for a blog. :)
Nothing is safe on the internet, theres always someone who can hack it.
The only question is: is it worth to hack it. :)

BTW, is there also something like a editor for my blog. Because HTML
gets escaped and when I do enter it does not work :(.

[Mladen Milankovic]

Hi.

Yes there are. If you need more from the authorization you can expose those
too, or all of them if you want to allow registration on the blog.
Usually I work on things where registration isn't good thing, and I need only
login and logout.

If you want all the functions:
def user(): return dict(form = auth())

or some of them:
def login(): return dict(form = auth.login(next=URL(r=request, f="index")))
def logout(): return dict(form = auth.logout(next=URL(r=request, f="login")))
#any other function you need...

Hmm my posts were deleted. However, this is with profiles right? I
just want a plain login/logout system :$. And is there also something
like an editor. Because when I type my posts now I can't use enters
because everything is escaped. And the for loop does not work:

{{for post in posts:}}
{{=post.titel}}

{{=post.time}}

{{=post.post}}
{{pass}}

When I do this I get:

Web2Py 2009-04-25 12:19:05 Welcome to my new blog. This blog isn't PHP
but just Web2Py a Python web framework. Its really easy and simple. I
only need a new style without this green stuff. ~ Phant Welcome

Everything is just set together, how can I fix this?

Hi.

For the html editor, wouldn't know to recommend.
When you got the post for the blog, just put it into XML() helper. Like:
XML(post) This way it won't be escaped.

Hi.

You'll need to add html for formating in the view. You can also add the XML
helper if you want to have html code in the post. Like:

{{for post in posts:}}
<div>
<h1>{{=post.titel}}</h1>

<p>{{=post.time}}</p>

<p>{{=XML(post.post)}}</p>
</div>
{{pass}}

Thanks, but I meant more something like the wiki markup language.

[mdipierro]

from gluon.contrib.markdown import WIKI

{{=WIKI(text)}}

Phynthon (is it your name or nick? :-P),
You can use wiki syntax, but if you want to edit as in a WYSIWYG you
can add a javascript library that do this for you: transform a
textarea in a full-featured text formatter and return HTML code to
you.

See NicEdit: http://www.nicedit.com/
It is very simple and do what you want (if you do not want wiki).
