Re: settings and constants on a reusable app

Support an additional variable MY_APP_USE_OTHER_CONSTANT (MY and
MY_APP, are, I hope, not the prefixes you are actually using), which
defaults to False and which the project settings file can override to
True.

Re: javascript in django template not executed when request is sent via ajax

I've been poking around with the debugger. For reference, here's the code:

var $form = $('form.roll');
url = $form.attr('action');

var $report = $('#report');

$.ajax({
url: url,
data: $form.serialize(),
dataType: 'html',
success: function (html, textStatus) {
$report
.html($('#report', html).html())
.css({
opacity: 1.0
});
style_preview_table();
}


The html variable passed into the success function contains the entire
page, including the javascript. I tried doing:

$report.html(html)

But the parts of the page that were not the results (i.e. #report) all
were duplicated (the page was displayed within the page). But even
there, the javascript wasn't included in the page, even though is was
in the html variable.

$('#report', html).html() contained just the html, without the
javascript. What I need is some way to get both the javascript and the
html of $('#report') and then pass that into $report.html(). Are there
javascript or jQuery methods that will allow me to do that?

Alternatively I could extract the javascript from the html variable
passed into the success function. But then how would I make that part
of $report.html()?

Re: javascript in django template not executed when request is sent via ajax

If your web server is in fact serving the content with the incorrect Content-Type header (You can verify this by inspecting the response in the Net tab of Firebug or Chrome) jQuery can convert the response regardless of the content-type if you specify a two space-separated values in your dataType. Try dataType: "text html" in your $.ajax function.

Re: adding fields into another apps forms (in plugin style)

I think he wants to load the plugins in a dynamic way. If you look how the admin package of django works you will have the answer:

The class AdminSite has a method register, which adds a model, on which the site builds itself. So each plugin can register its own admin stuff in a admin module.

Your task is to write your own class that registers plugins and to make a global instance of it.

Re: invalid keyword argument for this function

Yes its different.I was trying to say i tried your way and get rid of that error.

Thanks

This is a different error, and I don't see anything in the code snippet that might have caused this error (except if you are doing something in the Event model's save method)

You would need to debug it further, and pinpoint the location of this error.

Hi Nikhil,

Just to reiterate :), you need to remove both event_public & even_genre while creating the instance of the model, since both of them are M2M Fields. Take a look at the example in my previous mail.

If you are getting this exception somewhere else, please send that code snippet so we might able to see the problem.

Thanks,

Hi Nikhil,

You can not use an object's M2M field until it has been saved to the db.

So, you would have to call the "save" method on the instance, or use "create" method to create the instance.

            category_obj = Category.objects.create(
                            type = categoryform.cleaned_data['type']
                            )
            event_public = categoryform.cleaned_data['event_public']
            event_genre = categoryform.cleaned_data['event_genre']
            category_obj.event_genre.add(event_genre),
            category_obj.event_public.add(event_public),
            # No need to call save here
            # category_obj.save() 

The reason behind this is that M2M Fields are represented by intermediate tables with references to the two linked objects. If you need to add a row in it, both referenced objects should already be saved in the db with valid primary keys.

Re: Use regular expression to retrieve all image tags from a given content

Why not use html parse lib? BeautifulSoup(http://www.crummy.com/software/BeautifulSoup/) for expample
