[web2py] Re: json and URL
Solved.
I have found an answer from Massimo:
https://groups.google.com/forum/#!topic/web2py/aqECpxiPTqw
A code like
Field('data','text',filter_in=(lambda x: pickle.dumps(x)),filter_out=(lambda
s: s and pickle.loads(s)),default=None)
works fine.
But why is it not possible to use json?
2014-03-30 0:11 GMT+01:00 Martin Weissenboeck mweis...@gmail.com:
Let's say I have
URL(f=myfunction, vars=dict(x=1))
or
v = {f:myfunction, vars:{x:1}}
URL(**v)
That works fine.
Now I do
j = json.dumps(v)
I store j in
Field(url, requires=IS_JSON())
Now I read this field and call URL(**fieldvalue). I get an error:
type 'exceptions.SyntaxError' when calling URL, function or function
name required
The fieldvalue I get is
{'u'f : u'festfunction' ... }
The key is a unicode string and not utf-8 coded.
What is wrong? How can I get an utf-8 string?

[web2py] Re: json and URL
First, you don't need to explicitly specify the validator, but if you do,
it should be IS_JSON(). Second, once you select a record, you do not need
to pass the resulting value to json.loads() -- web2py will automatically
convert the stored JSON value to a Python object (that's the point of the
JSON field type).

*db.py:*

v=db.antworten.insert( nn=d, )
return dict(form=v)
The result of the print statement:

I put a dict with a *str* into my table and I get back a *unicode.*

First, take grid out of BEAUTIFY -- not necessary.
Does db.t_dogs happen to have a field called name? If so, change the name
of your extra input element to something other than name.
Also, when typing in your input field, open the browser developer tools and
see if (a) you get any JavaScript errors in the console and (b) an Ajax
request gets sent to the server.

But if I create a name such as, for example, color, I'd need to access the form variable thusly: form.vars.color. Since the name was created on the fly, how can I actually say form.vars.color?? If the name was created and stored in a variable, say, x, I can't say form.vars.x. I guess I don't quite understand Python's capabilities.

[web2py] web2py form submit does not take custom widget with x-editable fields
I am trying to use x-editable fields rather than plain INPUT in my model as
in:
def string_editable_widget(field, value):return A('', _href='#', _class=%s
myeditable % field.type, _name=field.name, \
_id=%s_%s % (field._tablename, field.name), _value=value, \
requires=field.requires, **{'_data-type': 'text'})
db.define_table('person',Field('name', 'string', widget=string_editable_widget))
The fields are displayed on the form as expected, however when I submit, it
shows Errors in form. Digging deeper, I noticed, when I use plain INPUT,
the post request contains:
Content-Disposition: form-data; name=name
Some name
Yet, with the custom widget, the post request does not contain the above at
all, which means the form is not grabbing inputs from the x-editable fields.
Please help on how to connect these two.

Re: [web2py] Re: Dynamically Creating a Form
Try form.vars['color'] or take a variable v v=color form.vars[v] 2014-03-31 2:32 GMT+02:00 horridohobbyist horrido.hobb...@gmail.com: But if I create a name such as, for example, color, I'd need to access the form variable thusly: form.vars.color.

Re: [web2py] Re: Dynamically Creating a Form
Yes, that will do it. form.vars (as well as request.vars and many other web2py objects) is a gluon.storage.Storage object, which is much like a dictionary and allows dictionary-like syntax for accessing items. Similar syntax works with DAL Table and Row objects.

[web2py] Google Datastore
A number of recent of events had let me to take a second look at the Google
Datastore. It has improved a lot since the early days and it is a great
tool to build scalable applications.
Web2py supported it form the earliest times. Web2py also supports NDB, an
interface to the datastore that uses memcache to speed-up searches.
Now it is easier then ever:
1) setup web2py for GAE
$ web2py.py -G config
Your GAE app name: test1
optional: edit app.yaml
2) run the local development server
$ dev_appserver.py --port 8080 ./
(this comes with the GAE SDK)
3) in your models use
db = DAL('google:datastore+ndb')
