dict values error in python 3.6

[Maurice Waka]

Hallo,

While creating a db, 

def create():
    form = SQLFORM(db.food_data,submit_button=T('Submit'))
    form.element('input[value=Submit]')['_style']='background-color: #DA2128; color:#ffffff'
    if form.process().accepted:
         response.flash="form accepted"
         redirect(URL('default', 'searching'))
    return dict(form=form)

Trying to enter data, I got this error:

Traceback (most recent call last):
 File "/home/mauricewaka/web2py/gluon/restricted.py", line 219, in restricted
 exec(ccode, environment)
 File "/home/mauricewaka/web2py/applications/HWell/views/generic.html", line 81, in <module>
TypeError: 'dict_values' object does not support i

Seems a python3 vs python2 related error?

Can you try to run your app with python2 for testing please ?

Ok on p2.

But I'm shifting to p3. 6

Ok, could you file an issue on github for. This please?

Probably something misusing a dictionary values() method in your models. It's expecting a list which can be accessed that way but it's getting a dictionary values generator in python 3. Can we see your models?

This is a issue with generic.html. In Python 3 dict.values() does not return a list it returns a dict_values object.

On line 10 of Generic.html wrap the values method call in list() and it works.

{{=BEAUTIFY(list(response._vars.values())[0])}}

also use session.flash="form accepted" or you won't see the flashed message after the redirect.

    if form.process().accepted:
         session.flash="form accepted"

[Maurice Waka]

Yes. It works!
