Re: storing django object into javascript variable/array

Hello,
I apologize for seeming too impatient or rude, actually I'm a bit in a
hurry because I was given a project
and was told that it was urgent. I miscalculated how much time it was
going to take me to learn django
Anyway, what I want to do is to use the variables variables
city_schools, city_latitudes and city_longitudes
as javascript arrays in a separate js file
For instance, like this
//INSIDE JAVASCRIPT FILE
for(var i = 0; i < city_schools; i++){
shouldn't this be:
for(var i = 0; i < city_schools.length; i++){
var lat = city_latitude[i];
var long = city_longitude[i];
googlemap.addmarker(lat, long);
..
}
//END
The whole point here is to add markers to an existing google map.
Somehow the variables store the data from django into the js arrays, but
I am unable to access them they way I want, so I was wondering if I
need to do anything extra before manipulating the js arrays.
Any suggestions would be welcomed
Thanks, and again sorry for seeming rude/desperate, it was all my fault

Hello,
I've posted my question before, but I believe I didn't provide
enough
detail. I intend to present my issue again, this time with more
detail.
Let me tell you that I am not a django developer, so I have very
limited exposure to django. I just know html, css, javascript,
jquery,
php (also java and c++, so I'm familiar with object-oriented
programming).
...
Now, I manage to see the output of the javascript written above
through Firefox's "View - Page Source" and it comes up like this
//BEGINNING
var city_schools = ["EC","St. Giles Central","St. Giles
Highgate"];
var city_latitudes = ["58","88","25"];
var city_longtitudes = ["7","99","100"];
//END
I have a separate javascript file where I add the code for the
google
map. What I want to do is to be able to access each of the
city_schools, city_latitudes, and city_longitudes and use its
data to
I can mark the schools inside a google map. It would be ideal if I
could retrieve the info as if it was a js array, but any
method that
works is more than welcome
What you have is very clearly a JavaScript array, as you asked for
the first time you posed this question. In fact, by copying the
code, you have produced three JavaScript arrays.
What you haven't done, in this newest version of your question, is
show exactly what it is you want. We now have a rough idea of what
your models look like, but no idea at all why the JavaScript
output you have pasted is insufficient.
You say that you know JavaScript, so what you're going to have to
do is come up with a sample of what you'd *like* to see as the
template output, and hopefully we can help you with the Django
template code to produce that output.
[Also, it really doesn't help to be posting and reposting the same
question, just hours apart -- it just looks very impatient]

Writing a DB backend
I am working on a app that keeps information in a non-SQL database composed of XML files referenced as UUIDs. In the prototype I'm directly referencing these using a simple api. For the production version I'm wondering if it would be possible to build a db backend that would allow me to use the django models and model forms. Does this seem like a reasonable thing to try? Are there examples of backends that do something similar? Or is this just to difficult to add in for the hoped for gain in using django models?

Problem with django auth login_required and lighttpd
I'm trying to serve django pages using mod_fastcgi from a lighttpd server. Everything works well using the setup recommended in the documentation except for the initial login. The porblem seems to be that when the user tries: http://server/ the login page comes up with a url of: http://server/accounts/login/?next=/mysite.fcgi/ After the user login lighttpd returns a 404 looking for http://server/mysite.fcgi/mysite.fcgi How do I fix this? A change in urls.py or a change in lighttpd.conf? Thanks john -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: GUI builder for django
Does everyone code the html and css by hand for their templates? That seems very time consuming and tedious. Desktop apps have the same issues with variations of languages, fonts, etc. and resizing and the layout containers and other widgets provide for dynamic changes. GUI builders make it easy to create the views from the basic widgets without having to program a lot of low level code. Are you saying there isn't an equivalent type of development tool in the web design space? Thanks John On 04/21/2010 03:10 PM, andres osinski wrote: No, and it's not a good idea to do WYSIWYG development for HTML. HTML is not a format that produces static content; it varies depending on screen fonts, browser, and platform, and getting that right means sticking to relative layout, making content flow, and taking care of quirks. WYSIWYG editors don't do any of that. and the quality of their output is dubious at best. Taking the time to produce sane HTML and CSS is a must for web development, but it's not that difficult a task and the knowledge to do it can be learned in a few days.
