How can I pass my context variables to a javascript file in Django?
Solution 1:
In addition to Andrzej Bobak's answer, you can also generate a global variable in Javascript from your template. For example, your template might generate code like this:
<script>
var my_chart = {{ the_chart }};
</script>
Your script could then refer to my_chart
.
Solution 2:
I don't think it's possible this way. If you want to access some data provided by the view, you have to pass it to the js function.
Example
js file:
my_cool_js_function(some_param){
// do some cool stuff
}
view
// some html code
my_cool_js_function({{param}})
hope this helps :)
Solution 3:
I would also add because I ran into the error a few times that if the python variable is an object it will throw a syntax error unless you put it in quotes, in other words, within your template,
<script>
var my_var = '{{ python_object|escapejs }}';
</script>
Furthermore, before putting that object in the context it is best to first serialize it to JSON, or you'll end up having to do string parsing. I found also that date objects needed to be converted to strings before this step.
import jsonpickle
context['python_object'] = jsonpickle.encode(python_object)
And finally, in the JS you can then iterate through the object properly and use the values as you probably would have in python by doing:
var my_var_parsed = jQuery.parseJSON(my_var);
