After successfully adding a pot file to my new i18n folder in my local machine, as well as setting "translate=True" in a couple of fields in my carddecks module, and verifying that in localhost I could acess my model data, I decided to update my server.
But when I try to access my model data I get the following error:
LINE 1: ..."write_date", COALESCE("carddecks_card"."cardText"->>'pt_PT'...
^
HINT: No operator matches the given name and argument types. You might need to add explicit type casts.
Anyone might know what may be causing this?
source code for the module can be found at https://github.com/diogocsc/carddecks

Found the answer for this. In my localhost I was updating my module. In my server i was just running docker-compose up. Not updating the module in the db.
The solution was going to settings -> apps search by cardecks and upgrade it.

I was able to set to set the credentials for Google's translation but with texttospeech I'm having a lot of trouble. First, I couldn't get the credentials as a json file, but got it as just a string. I haven't been able to find anyone else whose credentials are strings every one else has a json file. I converted the string to a json file but I don't think that is helping because it seems that they json object has to be a dictionary. In any case when I try this:
from google.oauth2 import service_account
key1 = 'key.json'
credentials = service_account.Credentials.from_service_account_file(key1)

I think this is because my json object is not a dict but a string. But the key that Google gave me was a string and not a json file, so I really don't know what to do here. Plus their documentation is too hard to understand.
When you say you have a string, are you referring to the Key ID? You will still need the json file associated with that key.
To create a new json file, go to Google Cloud Console -> IAM & Admin -> Service Accounts. Select one of your service accounts and click "Create Key" which will download the key as a json file. It can only be downloaded once.
I cannot submit Chinese words in the form.
English word is OK.
How can I set the utf-8 ?
In the html or app.py? or html code?
Here is my page: http://shiqiu.pw/testpage
PS: I can submit Chinese word in my mac, no problem. But when I deploy my code to my server, Chinese word can not be submitted, it shows Internal Server Error
PPS：I send my post words to mysql, and then show mysql data in new page, perhaps there is something need to set with my mysql?

The view function did not return a valid response. The return type must be a string, tuple, Response instance, or WSGI callable, but it was a InternalError.
My input Chinese charactor is showed as '工作'
I don't know which is the Internalerror object.
Full code is at github,code maybe not the same, but not big difference.
I have tried request.form.getunicode('word').
Also, I tried app.config['JSON_AS_ASCII' = False).
Or, set <meta charset="UTF-8"> in the html code.
BUT, no one works.
I hope the form can support Chinese words as value.
I am new to psychopy and I have written a small piece of code to display fixation point. Everything works fine, if I do not set the option "stereo=True" or "stereo=False"
But the moment I set "stereo=True", it fails with exception
"stereo=True fails with exception "pyglet.window.NoSuchConfigException"
What am I missing here? Any help would be very appreciated.
I need to use this to supports quad buffers.

Background
We're using Flask to develop a fairly simple application to "scratch an itch" we realized we had while working on a previous project. Session management is handled through the Flask-Login extension, coupled with the Github-Flask extension which we use for user authentication. The app uses Flask-SQLAlchemy and Psycopg2 (2.6.3) to connect to a PostgreSQL 9.1 database where user data is stored.
Issue
When the app is run locally (or deployed to a remote server) for testing we're seeing a strange condition during the first login attempt. The first time I log in I successfully get through the Github authentication sets, but immediately see this error.
DataError: (DataError) invalid input syntax for integer: "None"
LINE 3: WHERE "user".id = 'None'
^
'SELECT "user".id AS user_id, "user".date_created AS user_date_created,
"user".date_modified AS user_date_modified, "user".nickname AS user_nickname,

"user".github_access_token AS user_github_access_token, "user".github_id AS
user_github_id \nFROM "user" \nWHERE "user".id = %(param_1)s' {'param_1': u'None'}
I can close the browser tab and then revisit the application URL and see the same message. However, if I close the browser window, completely clear my browser's cache, and then attempt to log back in, it works as expected and I'm able to use the application. From that point on I can log out, switch browsers, clear browser cache again, etc., and there don't appear to be any problems -- it's only that first login until browser cache is cleared that this happens.
My testing shows that this happens on any user and two different users can be in two different states at the same time (one has cleared cache and now isn't having problems, the other who hasn't taken those steps is still stuck in the error state.
Originally we used a local SQLite database instead of Postgres. The issue does not exist there. It only has occurred since the switch to Postgres.
I'm at a loss for what steps I can take to remedy this situation. So far the questions I know to ask haven't been able to lead to the right answers when I search online.
For reference, I'll include the full stack trace as well.

Resolved!
This was a race condition. During the login process our application redirects an authenticated user to their profile page. This was getting triggered correctly, but for new users it was getting called before the user was actually committed to the database.
Visually it happened at the same time, so you could confirm that the callback was supplied with the "right" information, but it wasn't until I deconstructed and then reconstructed the login steps that I realized that it was hitting the route just before the record was actually committed to the database. Since the function that added the record wasn't interrupted by the redirect it did what it was supposed to do, but just a hair late.
Perhaps someone else will find this extract of my code helpful when troubleshooting a similar issue:

File "/usr/lib/python2.7/wsgiref/util.py", line 30, in next
data = self.filelike.read(self.blksize)
AttributeError: 'str' object has no attribute 'read'
But when I change the StreamingHttpResponse to HttpResponse,the error is as follow:

Use `StreamingHttpResponse`instead if you need the streaming behavior.

Thanks in advance!
You're calling the read method in:
wrapper = fs.get(file_id).read()
So you're getting a str (assuming Python 2, if 3, you're getting bytes). FileWrapper needs file like object, which of course str is not one.
Try to use:
wrapper = fs.get(file_id)
This will return file like object.
OTOH, pymongo's .get() returns a GridOut instance, which already supports iteration, so why not try something like:
wrapper = fs.get(file_id)
response = StreamingHttpResponse(wrapper, content_type=file_['contentType'])
