copied!<p>Here's the key part from the django docs on <a href="https://docs.djangoproject.com/en/dev/ref/forms/api/#bound-and-unbound-forms" rel="noreferrer">bound and unbound forms</a>.</p> <blockquote> <p>A Form instance is either <strong>bound</strong> to a set of data, or <strong>unbound</strong>: </p> <ul> <li>If it’s <strong>bound</strong> to a set of data, it’s capable of validating that data and rendering the form as HTML with the data displayed in the HTML. </li> <li>If it’s <strong>unbound</strong>, it cannot do validation (because there’s no data to validate!), but it can still render the blank form as HTML.</li> </ul> </blockquote> <p>You can't really see the difference for the example form you gave, because the form is valid in the "bound data" style. Let's extend the form by adding an <code>age</code> field, then the difference will be more obvious.</p> <pre><code>class MyForm(forms.Form): name = forms.CharField() age = forms.IntegerField() </code></pre> <h2>Bound form</h2> <pre><code>my_form = MyForm({'name': request.user.first_name}) </code></pre> <p>This form is invalid, because <code>age</code> is not specified. When you render the form in the template, you will see validation errors for the <code>age</code> field.</p> <h2>Unbound form with dynamic initial data</h2> <pre><code>my_form = MyForm(initial={'name':request.user.first_name}) </code></pre> <p>This form is unbound. Validation is not triggered, so there will not be any errors displayed when you render the template.</p>
