Hello.

Is it possible to use Button('cancel', 'Cancel') in FormActions to redirect to another view?

Without crispy, I use this in my templates:

<a class="btn" href="{{ object.get_absolute_url }}">Cancel</a>

But crispy's Button() generates a <input type="button" class="btn" value="Cancel"> which in my case doesn't nothing*. An Submit() generates a <input type="submit"..... which then generate errors in the form because the form goes to the view, the view tries to validate the form, etc., etc. (I'm using class based views).

Is the only way using HTML()?

Thanks!

  • Of course, maybe I'm doing something wrong :-/

This is what I ended up doing.

        cancel_url = reverse('<object>:list')
        if self.instance:
            cancel_url = reverse('<object>:view', kwargs={'pk': self.instance.id})

        self.helper.layout = Layout(
            ButtonHolder(
                Submit('submit', 'Submit'),
                Button('cancel', 'Cancel', onclick='window.location.href="{}"'.format(cancel_url))
            )
        )

Button('cancel', 'Cancel', onclick='history.go(-1);')

I instead use this to create a cancel button:

HTML("a class='btn' href='{% url \"cancel_url\" %}'>Cancel")

what is in your base.html?

flyingfoxlee commented Mar 17, 2014

I use crispy_forms with html5-boilerplate and bootstrap3, got the result as follow
screen

The right and left side of the rendered page exceeds the boundary of the browser.
Zoom in or zoom out won't help.
Also, it seems that it treat the web browser as a mobile one. In fact, it's on laptop.

I get this right by wrapping the form in a container div. Thank you for this great app.

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

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'

    Field('textarea', rows="3", css_class='input-xlarge'),

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']

    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'),
