Hello everyone.
Could you tell me how to create a new record in database without
submit buttons?
I actually would like to do it by the onclick event.
I know that I can call the ajax function like this.
But I don"t know what I have to write in the 'def:writing'.
My code implemented by a submit

What would extension=None do? It seems to make the most semantic
sense, to me at least.
In the method called by the AJAX event, you don't need the form at all. You
can just do a straight insert. You must pass the data to be inserted as
part of the AJAX call, either via args, or post data or some other method on
the URL. Then, inside writing(), just do a direct DB insert as docum
'Insert' method. That is what I wanted to know.
Thank you so much!!

If you format this post in markmin and email it to me, I'll add it to the
book as an additional subsection after Apache setup.
Added here:

Please verify that I got the details correct. Also, in future if you want
something fixed in the book just email me directly and I'll get it done
ASAP. My ability to follow the groups closely waxes and wanes relative to
how busy I am
I have found that only the *new *Google Groups is working reliably. Using
the old system has become very unreliable.
Hi, I have a very simple case use that I'm not able to solve using GAE:
I have a file with the content of two tables (cities and provinces). Cities
have a db.provinces field, and when I start a new aplicacation I use to
populate these tables using data from a module with this structure:

GAE is a NoSQL database http://en.wikipedia.org/wiki/NoSQL

Can you explain to me why you prefer ajax=False to ajax=True? What
advantages do you expect?

Where is that link? That was replaced by http://web2py.com more than 3
years ago.

The code for URL does this:
if extension is None and r.extension !=
Note, in that case, you won't be taking advantage of any of the built-in
form processing, such as input validation and return/display of form errors.
To get the validation, you could use the .validate_and_insert() method, but
you'd still have to manually process and deal with the potential valid

With ajax=False I don't need some javascripts on every page.
I can just add {{=LOAD('voting', 'voting_viewlet', ajax=False)[0][0]}}
in layout.html, and on every page users can vote (for example),
because ajax=False passed vars of current request to LOAD. And I liked

You were right Anthony.
And I found what I exactly needed was 'Components' .
I didn't want to refresh the entire page.
But anyways, the fact that there is the insert method and it doesn't give me
much to create a record from input forms, was new knowledge for me, so it
was good to know about it.

Defaulting to 'html' is not what we want. In general, we don't want to see
explict 'html' extensions in our urls. Instead, web2py is set up to
interpret urls without extensions as 'html' view requests. If you explicitly
pass 'html' to URL() as the extension, it will add it to the URL --

The point regarding backwards compatibility is well-taken, I wouldn't want
to mess with that at all. However, cognitive dissonance in code is a
particular bugbear of mine. I am especially nervous (in general) of
situations where one thing is used to *sematically*

Yes, I can include templates with {{include}}, but I can't process

I believe templates that you include will have access to the current
request.vars. You should even be able to call functions from views (though
they would have to return HTML or some objects your view can then handle).

Getting more comfortable with Web2Py and there sure is a lot to like about
it.
I'm wondering what is considered best practice for inserting records that
might already exist, when I also want to get the id of the record if it does
exist. I haven't come across a shortcut for this.
For now, I'm usi
Greetings,
I just installed Instant Press and am trying to figure out how to skin

it's not real specific on what to name those files. I've tried

Be careful about using an 'except' without specifying specific exception
types -- that code will attempt an insert regardless of the reason for the
failure in the 'try' clause.

I'm getting some unexpected 404s. Is there any way to make sure any route
caching is flushed? Any other ideas what might cause the problem? Nginx +
uWSGI on Ubuntu.
False alarm. Missing view. Have missing views always generated 404s? I know
the generics changed so missing views used to be rare.
