[Fixed]-Using Django view variables inside templates

✅

In order to have access to a variable in a template, it needs to be in the the context used to render that template. My guess is you aren’t passing a context dictionary to the template when you render it.

http://docs.djangoproject.com/en/dev/topics/http/shortcuts/#render-to-response

The “dictionary” referenced there is a dictionary that contains all the variables you want to have available in the context. For example:

return render_to_response('your_template.html', {'h': h})

As far as the “no error” error goes… That’s the default setting for an invalid template variable. You can change that in the project’s settings if you’d like.

You can also use

return render(request, 'your_template.html', {'h':h, 'var1':var1})

Refer to the latest manual on https://docs.djangoproject.com/es/1.9/topics/http/shortcuts/

Yes! This is normal. Such errors in templates fail silently and this is expected in Django.

to render properly template use render_to_response('your_template.html', {'h':h}) (there is also a nasty shortcut render_to_response('your_template.html', locals()) if your context dictionary is very big)

here is some explanation with examples: http://www.djangobook.com/en/beta/chapter04/ (section ‘How invalid variables are handled’)
