[web2py] Problem trying to insert an image with CKEditor and SQLFORM

[Michael Ellis]

Not sure if this is a web2py or ckeditor problem or just some
misunderstanding on my part.  Here's what's happening:

If I create a CKEditor instance in a SQLFORM, things work as expected until
I try to insert an image. Clicking the Ok button in ckeditor's image dialog
appears to be causing an immediate and unwanted form submission with a
formkey that doesn't match the real formkey. This doesn't raise a form
error. Instead it triggers the final else branch of the form.accepts logic
(see below) and the image along with any other text that was entered is
lost.

I recently ran into this in a larger app, but am able to reproduce it in the
following minimal model and controller. Has anyone else run into this and is
there a workaround other than switching the CKEditor to Source mode and
manually entering the <img> tag? I'm using web2py1.79.2 and CKEditor 3.3.1
(revision 5586) but have also seen the problem in CKEditor 3.2.


MODEL
db.define_table('page',
    Field('body', 'text'),
    )

def advanced_editor(field, value):
    eid = str(field).replace('.','_')
    return TEXTAREA(_id = eid, _name=field.name,
                    _class='text ckeditor', value=value,
                    _cols=80, _rows=10)


db.page.body.widget = advanced_editor

VIEW (default.py/index.html)
{{extend 'layout.html'}}
<script type="text/javascript"
src="{{=URL(request.application,'static','js/ckeditor/ckeditor.js')}}"></script>
{{=BEAUTIFY(response._vars)}}


CONTROLLER
def index():
    form = SQLFORM(db.page, showid=False)
    if form.accepts(request.vars,session):
        response.flash = "Form accepted"
        redirect(URL(r=request,f="show"))
    elif form.errors:
        response.flash = "Uh-oh!"
    else:
        ## Trying to insert an image lands here.
        response.flash = "Fill out the form."
    return dict(form=form)


def show():
    shown = dict()
    for row in db(db.page.id>0).select():
        shown[row.id] = row.body
    return dict(shown=shown)



Thanks,
