passing in forms into HTML page django

Question

I am currently learning Django and I was wondering if I am understanding all of this correctly. In my views.py, i created an args dictionary with args={}. I passed in 2 values into args with args.update(csrf(request)) and args['form'] = MyRegistrationForm(). I was wondering in the line return render(request, 'register.html', args), am I passing in an empty form from args['form'] into the HTML page where it is labeled {{form}}?

my register.html:

{% extends 'base.html' %}

{% block content %}

    <h2>Register</h2>
    <form action = '/accounts/register/' method = 'POST'>{% csrf_token %}
    {{form}}
    <input type = 'submit' value = "Register" />
    </form>

{% endblock %}  

my views.py:

def register_user(request):
    # second time around
    if request.method == 'POST':        # look into request.method and see if it has POST
        form = MyRegistrationForm(request.POST)     # pass through the values in the POST to the custom form to create form object
        if form.is_valid():             # check if information if correct
            form.save()                 # if correct, save form, and that will save the registration information for the new user
            return HttpResponseRedirect('/accounts/register_success')

    # first time around
    args = {}
    args.update(csrf(request))
    args['form'] = MyRegistrationForm() # BLANK user creation form with no information
    return render(request, 'register.html', args)       # passes 'form' from args into the html page

Yes.

Answer 2

See this docs. and try that:

{% extends 'base.html' %}

{% block content %}

    <h2>Register</h2>
    <form action = '/accounts/register/' method = 'POST'>
    {% csrf_token %}
    {{form.as_p}}
    <input type = 'submit' value = "Register" />
    </form>

{% endblock %}

Yes, args is set to a instance of your form MyRegistrationForm as form.

This is beyond what you have asked but I have recently used. if you want to customise your HTML further for the form you can use a for loop to loop through your form displaying labels and input fields corresponding to your model.

example below - using styled twitter bootstrap

<form class="form-horizontal" action="/accounts/register/" method="post">{% csrf_token %}
{% for field in form %}
  <div class="form-group">
     <label for="id_{{ field.name }}" class="col-sm-2 control-label">{{ field.label }}</label>
     <div class="col-sm-10">
        {{ field }}
     </div>
  </div>
{% endfor %}
<button type="submit" class="btn btn-primary" >Submit</button>
</form>

field.label - label

field - input field
