[web2py] Re: json Data from the server not displaying!
The problem is that you are creating the string you want to return and then
putting it in a dictionary. You could just have returned the string. That
said it's better to use response.json which does a few other things for you.
Try this
def dashboard():
call_clicks = db().select(db.dashboard.call_clicks)
social_clicks = db().select(db.dashboard.social_clicks)
profile_views = db().select(db.dashboard.profile_views)
data = {
'call_clicks': [c.call_clicks for c in call_clicks],
'social_clicks': [s.social_clicks for s in social_clicks],
'profile_views': [p.profile_views for p in profile_views]
}
return response.json(data)

[web2py] Re: Validator not saving images
Like I said I didn't test it :) apparently you need to seek to zero after
tesseract and not after image.open as tesseract is reading it. Fixed
version (which I actually tested):
# -*- coding: utf-8 -*-
import pytesseract
from PIL import Image
from pydal.validators import Validator, ValidationError
class IMG_HAS_TEXT(Validator):
def __init__(self, check_tokens=None, error_message="Image doesn't have
the required text"):
self.error_message = error_message
self.check_tokens = check_tokens or []
def validate(self, value, record_id=None):
try:
image = Image.open(value.file)
text = pytesseract.image_to_string(image).lower()
value.file.seek(0)
if not text or not all(token in text for token in
self.check_tokens):
raise ValidationError(self.translator(self.error_message))
return value
except Exception as e:
raise ValidationError(self.translator(self.error_message))
class IS_RECEIPT_OR_INVOICE(IMG_HAS_TEXT):
def __init__(self, error_message="The uploaded file is not a receipt or
invoice!"):
self.error_message = error_message
self.check_tokens = ("receipt", "invoice")

[web2py] Re: xmlrpc python3 error
Just in case it helps someone, I was able to change my code to make it
work. It's not a complete solution: I just started using args instead of
vars.
I'll explain: in the client I was calling the service with some query
string arguments, like this:
from gluon.contrib.simplejsonrpc import ServerProxy
ws =
ServerProxy('http://mysite.com/ws/call/jsonrpc?token=ce3e1298-b7b3-40f6-83f2-f78c4360db8d')
... and in the function exposing the service I was using the token to
identify the client:
from gluon.tools import Service
service = Service()
def call():
if not db(db.clients.token == request.vars.token).count():
raise HTTP(403)
return service()
So I just had to make this change in the client:
ws =
ServerProxy('http://mysite.com/ws/call/jsonrpc/ce3e1298-b7b3-40f6-83f2-f78c4360db8d')
... and this change in the service:
def call():
if not db(db.clients.token == request.args(1)).count():
raise HTTP(403)
return service()
I hope it helps someone.
Best regards,
Lisandro

[web2py] json Data from the server not displaying!
I have data that is in json format from the database, i want to draw a
graph with data but i'm not sure how to display it in my view in graph
format using the plotly library. My view code display nothing!
