Django passing value from template to view

Question

I'm having trouble passing values from my template to view. Basically I created a form for user registration, and want to pass the values from the template to view so that I can construct a User object to add to my database. But somehow my "input" is not working when I add name={{user_form.username}}. Also, I want to pass values 0,1,2 respectively when I select "borrower", "libarrian" and "clerk", what can I do to implement this?

Below are my codes.

      <form id="user_form" method="post" action="/sign_up/" class="form-signin" role="form">
          {% csrf_token %}
        <h2 class="form-signin-heading">Signup </h2>

            {% if error%}

        <div class="error"> Your registration has been unsuccessfull </div> 
        {% endif %}

        <input type="text" class="form-control" name="username" value="{{user_form.username}}" placeholder="Username" required autofocus>
        <input type="password" class="form-control" name="password1" placeholder="Password" value="" required>
        <input type="password" class="form-control" name="password2" placeholder="Retype password" value="" required>       


        <select class="form-control">
  <option value="2">Librarian</option>
  <option value="0">Borrower</option>
  <option value="1">Clerk</option>
</select>

        <button class="btn btn-lg btn-primary btn-block" type="submit">Sign Up</button>

      </form>

In forms.py

class UserForm(forms.Form):
    username = forms.CharField(max_length=30)
    password1 = forms.CharField(widget=forms.PasswordInput())
    password2 = forms.CharField(widget=forms.PasswordInput())

In views.py

   def sign_up(request):
    registered = False;
    error = False;
    if request.method == 'POST':
        user_form = UserForm(request.POST)
        if user_form.is_valid():
            registered = True
            username = user_form.cleaned_data['username']
            password = user_form.cleaned_data['password']
            user = User.objects.create_user(username, None, password)
            user.save()
        else:
            error = True;
    else:
        user_form = UserForm()

    return render(request, 'books/sign_up.html',
                  {'user_form':user_form,
                   'registered':registered, 'error':error})

Can you provide the template rendering line - how do you pass the form object to the template? — johnbarr

Below form should work.

<form id="user_form" method="post" action="/sign_up/" class="form-signin" role="form">
    {% csrf_token %}
    <h2 class="form-signin-heading">Signup </h2>
    <input type="text" class="form-control" name="username"  value="{{user_form.username}}" placeholder="Username" required autofocus>
    <input type="password" class="form-control" name="password1" placeholder="Password" required>
    <input type="password" class="form-control" name="password2" placeholder="Retype password" required>      
    <select class="form-control">
        <option value="1">Librarian</option>
        <option value="0">Borrower</option>
        <option value="2">Clerk</option>
    </select>
    <button class="btn btn-lg btn-primary btn-block" type="submit">Sign Up</button>
</form>

Changes I have done are -

Change the names of username and password textboxes
Change the type for username textbox
Added value attribute in select control

Why would changing to name="username" pass the value to user_form.username?

Anurag Over a year ago

Value should be passed to value attribute. Now edited my answer.

I don't quite understand your comment. You never mentioned value attribute above.

This didn't work. After adding value="{{user_form.username}}", my signup page simply had " placeholder="Username" required autofocus> outside the input box.
