How do you pass a Python variable to a template? And this is rather simple, because Django has built-in template modules that makes a transfer easy. Basically you just take the variable from views.py and enclose it within curly braces {{ }} in the template file.
{% %} and {{ }} are part of Django templating language. They are used to pass the variables from views to template. {% %} is basically used when you have an expression and are called tags while {{ }} is used to simply access the variable.
Django for loop counter All the variables related to the counter are listed below. forloop. counter: By using this, the iteration of the loop starts from index 1. forloop. counter0: By using this, the iteration of the loop starts from index 0.
Remember that the dot notation in a Django template is used for four different notations in Python. In a template, foo.bar can mean any of:
foo[bar] # dictionary lookup
foo.bar # attribute lookup
foo.bar() # method call
foo[bar] # list-index lookup
It tries them in this order until it finds a match. So foo.3 will get you your list index because your object isn't a dict with 3 as a key, doesn't have an attribute named 3, and doesn't have a method named 3.
arr.0
arr.1
etc.
You can access sequence elements with arr.0 arr.1 and so on. See The Django template system chapter of the django book for more information.
When you render a request to context some information -
for example:
return render(request, 'path to template',{'username' :username , 'email'.email})
you can access to it on template like this -
for variables:
{% if username %}{{ username }}{% endif %}
for arrays:
{% if username %}{{ username.1 }}{% endif %}
{% if username %}{{ username.2 }}{% endif %}
you can also name array objects in views.py and then use it as shown below:
{% if username %}{{ username.first }}{% endif %}
