How to get GET and POST request values in Django Templates?

Question

I want to be able to access a bit of information that someone places in a GET variable right in the template of a page (HTML escaped, of course.) How would I go about doing this? I know you can grab this information with views, but in this case, I'd rather handle it HTML side.

Can you be a bit more clear. How do you want to handle the GET and POST in your template. I am asking this because GET and POST are methods through which variables are sent to views and within the template. – Danidania

I'm using direct_to_template, and want to put one of the variables in a hidden value in a form. – Applied

Answer 1

You can pass that information from view to the template just as passing another variable. When you are rendering your template, just add a variable and pass request.GET QueryDict. You will be able to access all of the GET parameters within your template.

EDIT

direct_to_template automatically includes RequestContext(request) so you will be able to use all of your context instances in your settings. Please add 'django.core.context_processors.request' in your TEMPLATE_CONTEXT_PROCESSORS in settings.py. Afterwards, you will be able to use access Django's HttpRequest by {{ request }} in your template. Example settings, urls, and template are below:

settings.py

TEMPLATE_CONTEXT_PROCESSORS = (                                         
    'django.core.context_processors.request',

     # these are the default values from django. I am not sure whether they
     # are overritten when setting this variable, so I am including them             "django.contrib.auth.context_processors.auth",                  
    "django.core.context_processors.debug",                         
    "django.core.context_processors.i18n",                          
    "django.core.context_processors.media",                         
    "django.core.context_processors.static",                        
    "django.core.context_processors.tz",                            
    "django.contrib.messages.context_processors.messages"           
    )      

urls.py

urlpatterns = patterns('django.views.generic.simple',                      

    url(r'^about/$', 'direct_to_template', {'template':                    
        'about.html'}),
)                 

about.html

Your request is: <br /><br />                                                                                                                                                                                           

{{ request.GET }}

My hope is to avoid using a view in this instance. Is there no way to grab the variables without passing them explicitly from a view? I'm using direct_to_template, and want to put one of the variables in a hidden value in a form. – Applied

Have you tried in your view to access the information you want with request.get? Accordingly to django, direct_to_template adds RequestContext by default, which should enable you to access request parameters in your template. – Jewfish

Could you give an example and place it in the answer? It sounds just like what I want. – Applied

Here it is. Edited the answer. You can check it. – Jewfish

You'll also need 'django.contrib.auth.context_processors.auth' to avoid the KeyError on the admin panel. – Tamarisk

Answer 2

In new Django you can use directly in template like:

if post request with request.POST['name'] in view.py, in template you can use:

{{request.POST.name}}

if get request in template you can use:

{{request.GET.name}}

For example, if you submit the GET request values in index.html as shown below:

{# "index.html" #}

<form action="{% url 'my_app1:test' %}" method="get">
  <input type="text" name="fruits" value="apple" /></br>
  <input type="text" name="meat" value="beef" /></br>
  <input type="submit" />
</form>

Then, you can get the GET request values in test.html as shown below. *My answer explains how to get GET request values in Django:

{# "test.html" #}

{{ request.GET.fruits }} {# apple #}
{{ request.GET.meat }} {# beef #}
{{ request.GET.dict }} {# {'fruits': 'apple', 'meat': 'beef'} #}
{{ request.META.QUERY_STRING }} {# fruits=apple&meat=beef #}

And, if you submit the POST request values in index.html as shown below. *method="post" needs csrf_token tag in <form></form> otherwise there is error:

{# "index.html" #}

<form action="{% url 'my_app1:test' %}" method="post">
  {% csrf_token %}
  <input type="text" name="fruits" value="apple" /></br>
  <input type="text" name="meat" value="beef" /></br>
  <input type="submit" />
</form>

Then, you can get the POST request values in test.html as shown below. *My answer explains how to get POST request values in Django:

{# "test.html" #}

{{ request.POST.fruits }} {# apple #}
{{ request.POST.meat }} {# beef #}
{{ request.POST.dict }} {# {'csrfmiddlewaretoken': 'Vzjk89LPweM4loDWTb9gFNHlRQNJRMNwzQWsiUaWNhgBOr8aLfZyPjHobgqFJimk', 'fruits': 'apple', 'meat': 'beef'} #}
