    # This view is missing all form handling logic for simplicity of the example
    return render(request, 'index.html', {'form': MessageForm()})

init() got an unexpected keyword argument 'instance' ERROR

thanks for the example, it helped me solve some issues with my form, but I still got couple more.

is there a way to use chosen with AppendedText like

This works

AppendedText('user','a link to add a new user')

but this one does not work

AppendedText(Field('user', css_class='chosen'),'a link to add a new user')

the form displays chosen JS autofill but it does not show the link

1. What is the role of helper.class = 'form-horizontal'?
2. My form does not appear like a 2 column table, as in this example. What am I missing?

@sureshvv form-horizontal is from bootstrap I think

ImportError: No module named 'forms'

What to do?

How can i display radio buttons horizontally instead of vertically?? Same for the checkboxes. Can you show syntax for that in helper class?

Thanks.

Guys, I tried using inline as explained in documentation but it had no effect on the outcome. Below is my code. can someone help me identify what I am doing wrong?? Thanks.

helper = FormHelper()
helper.form_class = 'form-horizontal'                                                                                              
helper.layout = Layout(
    Field('text_input', css_class='input-xlarge'),
    Field('textarea', rows="3", css_class='input-xlarge'),                                                                         
    'radio_buttons',
    InlineRadios('radio_buttons'),
    Field('checkboxes', style="background: #FAFAFA; padding: 10px;"),                                                              
    InlineCheckboxes('checkboxes'),
    AppendedText('appended_text', '.00'),
    PrependedText('prepended_text', '<input type="checkbox" checked="checked" value="" id="" name="">', active=True),              
    PrependedText('prepended_text_two', '@'),                                                                                      
    'multicolon_select',                                                                                                           
    FormActions(
        Submit('save_changes', 'Save changes', css_class="btn-primary"),                                                           
        Submit('cancel', 'Cancel'),                                                                                                
    )

Hi.. Nice tutorial. Is there a way to output the submitted results on the same page when one clicks save changes, in form of a table?

Thank you in advance.

OP you saved my life by sharing this codes.

Thanks for this code its working perfectly

What if we are using a modelForm ? Like this below:

class BlogPostForm(forms.ModelForm):
    class Meta:
        model = models.Post
        fields = ['title', 'text', 'tags', 'author', 'slug']

@arindam31 I have the same question. i have got the form fields but can't seem to find a way to put text in front of the fields, for instance "Name:" in front of the text field to fill in the name. Any help guys?

What is in the base.html, please ?

@arindam31 I also had the same question, how can i work on it? can any any one help us

@rachuri333 I don't remember what I was trying to do back then . But this is what my form looks like.

class BlogPostForm(forms.ModelForm):
    class Meta:
        model = models.Post
        fields = ['title', 'text', 'tags', 'author', 'slug']
    helper = FormHelper()
    helper.form_class = 'form-group'
    helper.layout = Layout(
        Field('title', css_class='form-control mt-2 mb-3'),
        Field('text', rows="3", css_class='form-control mb-3'),
        Field('author', css_class='form-control mb-3'),
        Field('tags', css_class='form-control mb-3'),
        Field('slug', css_class='form-control'),
    )
