Adding cancel button - form submission

[Mathias]

Hello,

I have added a CANCEL button to my SQLFORM.

Form submission prevents the correct working of it.

I have tried to avoid form submission with this code :

def new_guest_contact():

   form = SQLFORM.factory(...)   

   

   form[0][-1][1].append(TAG.BUTTON('Cancel',_onclick='ajax("%s",[],":eval");return false' %URL(r=request,f='new_contact')))

   

   if form.process().accepted:

        ...

        redirect(URL(r=request,f='new_contact_part')) 

   elif form.errors:

       response.flash = 'form has errors'

   else:

       response.flash = 'Create new guest'

  

   return dict(form=form)  

If I click the cancel button now, nothing happens anymore.

Any help is welcome.

Thanks

Mathias

Maybe this could be enough??

{{=A(T('cancel'),_href="javascript:void(history.go(-1))")}}

It will bring you back to the precedent page, in my use case, I direct the user on a crud.read page where the user can edit the record (crud.update). Then if don't want make change anymore there is a "cancel" hyperlink that bring back the user on the crud.read page.

I found a good solution for me :

form[0][-1][1].append(TAG.INPUT(_value='Cancel',_type="button",_onclick="window.location='%s';"%URL(r=request,f='new_contact')))

In trunk:

form.add_button("Cancel",URL(r=request,f='new_contact'))

Has this "add_button" been added to one of the recent releases?  I'm running 1.99.7 and I get 

  <type 'exceptions.AttributeError'> 'SQLFORM' object has no attribute 'add_button'

Maybe it's time to upgrade :-)

Thanks,

Hi everybody,

Sorry for re-opening this thread, but I'm trying without success to add a cancel button to a CRUD form.

Here my controller:

def insertnews():
    form = crud.create(db.news)
    form.add_button("cancel",URL(r=request,f='index'))
    return dict(form=form)

Here my view:

{{=form.custom.begin}}
Body:
<div>{{=form.custom.widget.body}}</div>
{{=form.custom.submit}}
{{=form.custom.cancel}}
{{=form.custom.end}}

Where am I wrong?

Cheers,
David

When you add_button('cancel',....) you do not get a form.custom.cancel. Sorry.

No problem! :)

So, is there any method to customize the elements of a form (fields and buttons) without using a custom form?
Because I managed to customize it with form.custom... but then I can't add a cancel button.

Thanks a lot! :)

I use form.custom as well. Based on this thread, I included the following in the add() function of my controller:

cancel_button = INPUT(_type='button', _value='Cancel', _onclick='window.location=\'%s\';;return false' % URL('index'))

It has the same resulting code as form.add_button('Cancel', URL('index')).

I changed the URL() function to URL('view', args=[id]) for my edit() function. Then I just add {{=cancel_button}} next to {{=form.custom.submit}}.
