forms.Form.fields

Form.fields

You can access the fields of Form instance from its fields attribute:

>>> for row in f.fields.values(): print(row)
...
<django.forms.fields.CharField object at 0x7ffaac632510>
<django.forms.fields.URLField object at 0x7ffaac632f90>
<django.forms.fields.CharField object at 0x7ffaac3aa050>
>>> f.fields['name']
<django.forms.fields.CharField object at 0x7ffaac6324d0>

You can alter the field of Form instance to change the way it is presented in the form:

>>> f.as_table().split('\n')[0]
'<tr><th>Name:</th><td><input name="name" type="text" value="instance" required /></td></tr>'
>>> f.fields['name'].label = "Username"
>>> f.as_table().split('\n')[0]
'<tr><th>Username:</th><td><input name="name" type="text" value="instance" required /></td></tr>'

Beware not to alter the base_fields attribute because this modification will influence all subsequent ContactForm instances within the same Python process:

>>> f.base_fields['name'].label = "Username"
>>> another_f = CommentForm(auto_id=False)
>>> another_f.as_table().split('\n')[0]
'<tr><th>Username:</th><td><input name="name" type="text" value="class" required /></td></tr>'
