If I remove the decorator

@ui.in_background

I get an error:

TypeError: Cannot show camera from main UI thread

I know this is out of topic but I'm having trouble running this code. It freezes my app:

@ui.in_background
	def scan_document(self, sender):
		
		img = photos.capture_image()
		console.show_activity()
		if not img:
			return
		with io.BytesIO() as bIO:
			img.save(bIO, 'PNG')
			imgOut = ui.Image.from_data

I don't know if you guys know a lot about the photos module but I can't find any good documentation.

@ccc do you have a github post on it?

Thanks @ccc

Solved it!

the_action = getattr(self, name + '_action')
button.action = the_action

@techteej

Would this work?

def scan_view_action(self,sender):
    pass

def make_button(self,name):
    the_action = name + '_action'
    button.action = the_action

Or is there any convenient way to do this to keep it DRY?

I'm having a problem concatenating a string to a variable to create a method in my app. It goes something like this:

# coding: utf-8

import ui

w,h = ui.get_screen_size()
buttons = ''' Scan_View Show_View '''.split()

class OCRApp(ui.View):
	def __init__(self):
		x,y,w,h = self.bounds
		self.background_color = 'orange'
		self.present()
		for i, button in enumerate(buttons):
			button = str(button).lower()
			self.add_subview(self.make_button(button,i))
		
	def scan_view_action(self, sender):
		scanview = ui.load_view('scanview.pyui')
		scanview.background_color = 'red'
		scanview.present()
		
	def show_view_action(self,sender):
		pass 
	
	def make_button(self,name, i):
		button = ui.Button(title=name)
		**the_action = name
		button.action = the_action()**
		button.center =w/2, (i*60)+(button.height*2)
		self.add_subview(button)
		return button

OCRApp()
	

When I create a string on the variable 'the_action' and call it on 'button.action' I get an error ' TypeError: "str" object is not callable'.

How do I go about doing this correctly?

Great the first option seems pretty easy. I don't know if I can get all the testing done in only 200 request. But the second option seems pretty convenient also. Thanks for the help!

Hello. I want to work on something different but I don't know if pythonista supports it so please help. Here it is.
I want to create a program that takes an image (eg. taking a photo of an image with a large amount of text), reads the text and converts it to a manipulatable string. Does pythonista have this capability? If so, where do I start. Which modules should I import (pythonista or an external module)? I have a pretty good idea but if it's not possible I'll move to something else.

Thanks

@omz

So simple. But worked perfectly. Thanks

Yes and it gives me and error that the value needs to be a ui.Image

# example url
url = 'http://is4.mzstatic.com/image/thumb/Music7/v4/53/fc/a2/53fca253-84b1-f2cd-4e17-98be502ec53c/UMG_cvrart_00602547534873_01_RGB72_1500x1500_15UMGIM41882.jpg/55x55bb-85.jpg'

i = urlopen(url)
b= BytesIO(i.read())
img = Image.open(b)
btn = ui.Button()
btn.image  = img         #<<< TypeError: Expected a ui.Image
