Parse a javascript file having django template variables

[Alessandro Candini]

Hi everybody.

I have an application with the following structure:

STO
├── __init__.py
├── jsonopenlayers
│ ├── __init__.py
│ ├── models.py
│ ├── static
│ │ ├── css
│ │ │ └── STO.css
│ │ └── js
│ │ └── renderMaps.js
│ ├── tests.py
│ └── views.py
├── manage.py
├── settings.py
├── templates
│ └── jsonopenlayers
│ └── index.html
└── urls.py

Static files are found, but I have the problem that inside renderMaps.js
I have some Django template tag to be interpreted.
How can I tell Django to parse also that, in addition to my index.html?

Thanks in advance.

The only way you can manage this is to deliver that file not as a
static file, but as something that has been passed through the
template engine. The template engine can generate any content, be sure
to pass the correct content type ('text/javascript') when you return
the response, and use the cache_page decorator to avoid re-doing it
lots of times.

That is a pain, so a common work-around I use is to re-work it so that
the url to use is something that is passed to the function, and then
insert it into the appropriate templates.

Thank you, but I adopted the method indicated here:
http://stackoverflow.com/questions/6008908/use-django-template-tags-in-jquery-javascript

I have deleted renderMaps.js and created a new template named
index_renderMaps.html, containing only a script tag with inside the
javascript previously into renderMaps.js.
After that I have simply used an {% include "index_renderMaps.html" %}
into index.html template.

Or you can render the js file as if it was a template.
Put the javascript in a template directory.

In the main HTML, change the tag to something like <script href='/
myapp/jscript/renderMaps/'>

In your "urls.py" add something like

('/myapp/jscript/renderMaps','myapp.views.rendermap')

then in your views.py create a view:

def rendermap(request):
# create the variables you need here
var1 = "Hello"
address = Address.objects.get(id=1)
:
return render_to_response('renderMaps.js', locals(),
RequestContext(request))

You can see the idea, anyhow!
