Use the authentication data method in Django templates

This article mainly introduces how to use authentication data in Django templates. Django is the most popular Pythonweb development framework, if you need a friend, you can refer to the user currently logged in and his or her permissions. you can use RequestContext in the context of the template.

Note:

Technically, only variables such as RequestContext are available. And the TEMPLATE_CONTEXT_PROCESSORS setting contains "django. core. context_processors.auth" (this is the case by default), these variables can be used in the template context. When the TEMPLATE_CONTEXT_PROCESSORS settings contain "django. core. context_processors.auth" (this is the case by default), these variables can be used in the template context.

When RequestContext is used, the current User (a user instance or an AnonymousUser instance) is stored in the template variable {User:

{% if user.is_authenticated %} 
Welcome, {{ user.username }}. Thanks for logging in.
{% else %} 
Welcome, new user. Please log in.
{% endif %}

The permission information of these users is stored in the {perms} template variable.

You can use perms objects in two ways. You can use {perms. polls} to check whether a user has any permissions for a specific application. you can also use {perms. polls. can_vote} to check whether a user has specific permissions.

In this way, you can check the permission in the {% if %} statement in the template:

{% if perms.polls %} 
You have permission to do something in the polls app.
 {% if perms.polls.can_vote %}  
You can vote!
 {% endif %}{% else %} 
You don't have permission to do anything in the polls app.
{% endif %}
