I'm trying to use a parameter expression in the plone.app.theming theming-controlpanel that gets a value from the portal_registry to use within the rules.xml file of the theme.
The goal is that if a boolean is set in the registry, the theme can allow/disallow certain content.
So my parameter expression (in theming-controlpanel) is
enable_ad_tags = python:context.portal_registry['lw.portal.enableadtags']
There is a corresponding boolean field in the portal_registry.
The rules.xml file has this rule:
<!-- Global Ad Tags -->
<drop css:theme="#globalAdTags" if="not($enable_ad_tags)" />
The problem is that on my local machine i get this error in the console all the time:

Is there a problem with the pattern I am trying to use here?
Is there a better/safer way to achieve this?
Using portal instead of context works:
enable_ad_tags = python:portal.portal_registry['lw.portal.enableadtags']
IMHO context should also work, or context does not behave like it does, or the naming is wrong.

I've been having a problem lately where I can't access the value of any variable through their name. It's not a connection problem since I can read the value from the read() function just fine. However whenever I use the read_by_name function there's always the same error pyads.pyads_ex.ADSError: ADSError: Unknown Error (857212673).
Because it's an unknown error I haven't been able to find documentation on it. I'm using a BC9120 as a PLC and TwinCat 2. Does anyone know what might be causing this?
Code:
if self.plc.is_open == False:
self.plc.open()
print(self.plc.read(pyads.INDEXGROUP_MEMORYBIT, 0*8 + 0, pyads.PLCTYPE_BOOL))
print(self.plc.read_by_name("Test.M0", pyads.PLCTYPE_BOOL))

I am trying to use gspread, but I need the library to mesh well with another async library I am using.
After digging through the docs for gspread, I found this function that I can use:
class gspread.Client(auth, session=None)
An instance of this class communicates with Google API.
Parameters:
auth – An OAuth2 credential object. Credential objects are those created by the oauth2client library. https://github.com/google/oauth2client
session – (optional) A session object capable of making HTTP requests while persisting some parameters across requests. Defaults to requests.Session.
Which gives me an optional session parameter. How would I specify the session to use aiohttp?
I wrote a bit of test code, which compiles fine, but running the code crashes.
import aiohttp
import gspread
import random
from oauth2client.service_account import ServiceAccountCredentials
scope = ['https://spreadsheets.google.com/feeds',
'https://www.googleapis.com/auth/drive']
creds = ServiceAccountCredentials.from_json_keyfile_name('client_secret.json', scope)
c = gspread.authorize(creds)
client = gspread.Client(auth=c, session=aiohttp.ClientSession)
sheet = client.open_by_key('1Hkwo9gSpk3NjgPLPkG8kh0zBNw2nxsYWRw0cVdn0JA0')
ws = sheet.get_worksheet(0)
rcount = ws.row_count
msg = ws.cell(random.randint(1,rcount),1).value
print(msg)
The error message I get is below:

Any ideas?
It's impossible to use aiohttp with current version of gspread (3.0.1). the gspread library uses synchronous calls and aiohttp uses asynchronous calls.
Please, reconsider to use compatible library like requests or httplib2.
For anyone wondering, once I posted this question, I found that someone made an async wrapper for gspread. Check out the library here and show this guy your appreciation. I sure am!
I created fake header files under pycparser/utils/fake_libc_include for every header found in kernel/sched/core.c and put
#include "_fake_defines.h"
#include "_fake_typedefs.h"
into them. A few other header files where missing, lot's of headers from kernel/sched/sched.h for example. So I added them too.
Preprocessed the whole stuff with
gcc -nostdinc -E -Ipycparser/utils/fake_libc_include ../kernel/sched/core.c > core_pp.c
which gave no error.
So I tried to get the function names
python3 examples/func_defs.py core_pp.c
but it gives me the error:

What am I doing wrong? I've tried the redis example from this blog entry and it worked.
Adding the headers is just one part of the solution - this helps the preprocessor resolve the #include statements.
The other part of the solution is adding types that the parser would expect to find there to _fake_typedefs. This way pycparser will know the identified is a type and will be able to parse the code properly.
I have looked at the following links but none of them provide the solution I am looking for

PyMC error : hasattr(): attribute name must be string
I have to write a function which given the priors (and other stuff like data etc) returns a pymc model.
eg
m = pym.Model([fittable_params.values(), rv])
return m
and the in the calling function, when I do mcmc = pymc.MCMC(model)
It gives a long error

TypeError: hasattr(): attribute name must be string
On the other hand , if in the function (which returns a model), if I do
m = pm.MCMC([fittable_params.values(), rv])
it is running fine, but the function should return a model so that the user can do whatever he wants with the model in other parts of code.
If the linked solutions don't work for you then as a last resort you can just delete the non-string attributes from the model, since they don't seem to be used anyway.

if not isinstance(key, basestring):
del m.__dict__[key]
I have the following code, reads oauth2 token form file, then try's to perform a doc's list query to find a specific spreadsheet that I want to copy, however no matter what I try the code either errors out or returns with an object containing no document data.

then my second attempt

this returns an ResourceFeed object, but has no content. I have been through the source code for these function but thing are not any obvious.
Have i missed something ? or should i go back to version 2 of the api ?
