[web2py] Re: How to upload an image from React Native to Web2py?

[Mika Sjöman]

Yeah, I am back at it now. But I still dont seem to be able to save the 
object. Any ideas on how to save this object? I have tried and tried but I 
am just not able to save it :(

Yes I did both but I kept getting the same output no matter what I did.

[web2py] Signing in / register from React Native to Web2py?

[Mika Sjöman]

Hi

After extensive searching in the forum, docs and the internet, I feel that 
I can post the question here. I am building a React Native application, 
which means I don't have access to localstorage (this is not a web-app) - I 
think that I need to save some kind of login token in my React native state 
variable and re-send it for every request (being my best guess). Other 
implementations I found on the forum uses web-implementations with Angular, 
but since this is not a web-page, I need to handle this using just JS. 

I wonder if anyone here has experience of doing something similar? Is it 
possible to use a POST request using say axios to do something like this 
towards the login/register:

axios.post('myWeb2pyBackend/myapp/user', { username: 'myloginname', password
: 'test2' }) .then(function (response) { console.log(response); // if OK, 
save some token to state and resend with every GET request later }) .catch(
function (error) { console.log(error); });

Observe that this is Node.js that doesn't have access to the browser window 
variable or any other browser specific thing like localstorage. Would it be 
possible to get a JSON web token as a response from web2py that I resend to 
the server when the user asks for other resources which requires a signed 
in user? 

Cheers

Re: [web2py] Re: How to upload an image from React Native to Web2py?

[Mika Sjöman]

I tried that (up_file = request.vars['file[]']), but I still just get the
String printed out in my console:

"FieldStorage('file[]', 'mikasworld.jpg', '\xff\...base64 representation of
the image.

The strange thing is that the upload seems to go all right, but it never
saves the file. If I remember right, uploaded files just appears in the
/upload folder once complete, but this doesn't happen here. Strange
I am getting this ouput in my console, so for sure it upload the file and
given the request.vars response, it seems like the server is accepting the
upload but not saving the file. This is my output during the upload:

upload progress: 19.57139819860458%
ImageViewer.js:75 upload progress: 39.14279639720917%
ImageViewer.js:75 upload progress: 58.71419310569763%
ImageViewer.js:75 upload progress: 78.28559279441833%
ImageViewer.js:75 upload progress: 97.85698652267456%
ImageViewer.js:75 upload progress: 100%

Any ideas on why I get a FieldStorage object but not a saved file to disk
on the server? Is there any step I need to take after the file has been
uploaded that finally saves the file to disk?

Re: [web2py] Re: How to upload an image from React Native to Web2py?

[Mika Sjöman]

Hi

Yes it is a React Native mobile app :)  Since it is using native iOS
components, it is not possible to right-click and look at the DOM (it
doesn't have one because it is not a web page rendered inside a web-view).
Neither can I look at the network tab, because I only get a bridge to the
console by using the React Native debugger. I guess it is using the
javascript bridge from native iOS/Andriod back to react-native to send
messages back and forth. I can't monitor network traffic by using the
Chrome Webtools.

The strange thing is that I do get a response using my code that there is a
storage object, but there isnt any file on my disk with the name shown in
the response. I also thought that since I am getting a 200 response and I
am getting a Storage object, that it would be saved to disk - but that
doesn't seem to be the case :( So it... confuses me...

Hi and thanks :)

Ill try that later. But I need to keep the image outside of the db (not in 
a blob field), and only keep a reference to the location of the image on 
the disk. I am going to run a python script on the image I am uploading to 
do OCR analysis triggered by the Scheduler, so I need the image on the 
disk. How can I move the image to somewhere on the disk instead of saving 
it in the db?

[web2py] How to upload an image from React Native to Web2py?

[Mika Sjöman]

Hi

I am trying to upload an image from a React Native app to web2py. I am 
using a plugin called react-native-uploader, and when i upload the image I 
get a storage object when I return the request vars using the below code:

def upload:
return response.json({'vars': str(request.vars)})

When I print out the response in my Chrome dev tools, I get the following 
printout:


   1. 
  2. Object
 1. vars:""
 2. __proto__:
 3. 
 
Now I want to do two thing:
1. Move the file to a location accessible from web2py
2. send back a modified name of the file to the React Native client in a 
JSON object.

I have searched like crazy in the Google Group but also the web, but I cant 
find anything on how to do this. Any ideas?

Cheers

[web2py] Paypal Recurring Payments? Any experience? Any alternatives?

[Mika Sjöman]

Hi

I wonder if anyone here has implemented recurring payments with Paypal here 
with Web2py? Any experience with this and how to implement it?

We currently charge people for lessons with our teachers, but we would like 
to go over to a payment model where we automatically charge the customers 
every month. 

Is there a better way of doing this than Paypal? Market is mostly US and 
China based.

Re: [web2py] Re: Proposal for big but simple improvement: [add view] in IDE view

Wow that is wonderful! Web2py development will really become way smoother 
with this! I actually really enjoy the online IDE and not working with 
external apps. Fantastic to read that you took this suggestion so seriously 
and started working to implement it. I knew this was not that easy the 
second I wrote it though ;)

[web2py] Re: Proposal for big but simple improvement: [add view] in IDE view

[Mika Sjöman]

Well, I was thinking that usually you write the controller first. If you 
click an [Add view] button, it could check which functions are missing a 
view and give you two options in a popup, or pop-down? (don't know what it 
is called);

-
Add view for function:
  [Link: missing_view_function1]
  [Link: missing_view_function2]

OR add one with name:
Name: [  ] [Add View]
--

Mostly you would just click on the missing view function link and you would 
not misspell the file name, which is a quite common error and it would 
reduce writing. Also you would not add one by mistake if there is one 
already. 

// cheers

[web2py] Proposal for big but simple improvement: [add view] in IDE view

[Mika Sjöman]

Hi

I just noticed watching Massimo's video tutorials, how often we need to 
open a second tab in Chrome when we want to create a view/controller/model 
file. It often leads us to get conflicts since we do not want to close the 
previous (having multiple tabs open we are working on). 

If we could add a view with a button "add view" when looking at a 
controller and the list of views, we could basically stop opening multiple 
chrome tabs and also reduce the merges we need to do. 

*Edit views:* view1, view2, [Add view]

Clicking it would open the new text file immediately in another tab. 

It should also reload the files toggle view on the left. An [add or +] 
button could also be added after each section in the files toggle view to 
the left, and it would feel really complete. Even though I guess we would 
still open it sometime, it would reduce the times we need to click Edit 
link at the top bar.

[web2py] Re: Online classes

[Mika Sjöman]

Hmm... ok.

Thinking ... if it would be possible to use vimeo to integrate into a small 
"learn web2py website". Just need pause points to hide the video 
temporarily and show them again after the user has input commands into a 
text area field and has gotten them verified as correct. We actually do 
almost the same in our compnay, but with short videos at dominochinese.com 
where we teach Chinese using videos and quizzes. Or is this something you 
are planning to do yourself?

Cheers

[web2py] Re: Online classes

[Mika Sjöman]

Hi

Supper happy to see this! 

Two questions: 
1. could you cut them down a bit into smaller sections? 2.5 hour videos are 
a little bit too much to take in one time. 20 - 30 minutes max I would say 
is my personal attention span, preferably shorter.
2. is it possible to make it more like coursera or udacity? Watch video (20 
min), Practice with a quiz (write some short code to verify that I know the 
things), Answer a weekly quiz (after finishing 2.5h of video?).

Cheers!

[web2py] Re: How to measure conversion rate with google analytics?

[Mika Sjöman]

I have

But I get no conversion rates at all. Apparently it needs a special goal 
URL in Google Analytics to set up a goal (Bottom left). 

What I did was to set a new column in auth_user.just_registered with 
default value of True. If they come into the system with a True value, they 
get redirected to a success page which then moves them into the normal 
command central page. Quite smooth, and it could probably not be a part of 
web2py since conversion rate is really specific to each website, because 
you will have to figure out what a success is. 

Since this is mostly a standard thing (anybody using analytics and web2py 
would like to measure conversion rate for signups), maybe web2py should 
send all people to a register success page automatically that then 
redirects people to whatever URL they set as the destination.  

Cheers :)

[web2py] How to measure conversion rate with google analytics?

[Mika Sjöman]

Hi

I was wondering if it is possible to measure the conversion rate of how 
many people sign up to our service www.dominochinese.com with google 
analytics? If I understand it correct, I need to set up a goal URL with 
google analytics, but I then wonder how to redirect new users to that URL? 
Is there anything built into web2py so the stats become correct? I was just 
thinking that if I just redirect people who never signed in, I could 
possibly mess things up. 

Maybe I could just run a ajax call to the goal URL, if they are missing a 
database row value with the name has_signed_in_before? But will this give 
me the correct stats? 

Also any ideas on how to connect this to an Ad-words campaign?

I use both email login and Janrain for people to sign up. 

Cheers!

[web2py] Re: [web2py:27381] Re: MySQL - OperationalError: Error on rename (errno: 150)

[Mika Sjöman]

I am still getting allot of the same problems but now in 2013. When working 
on localhost and pushing to pythonanywhere, then I get these MYSQL index 
errors with 150 message. 

The way to solve it has been to add fake_migrate_all=True to the DAL 
connection, but then I can not do any database changes. Any idea on how to 
solve this? I have had this trouble for a week now without being able to 
drop the index from my mysql (web2py auth_user) table.

Re: [web2py] Re: Request: Course about Web2py & TDD + pledge for cash

[Mika Sjöman]

Hi looks great.

Why don't you make it a free coursera.org course and add a hundred thousand 
students to your class? I am moving to Sweden so California is a bit far to 
go even though I would love to study in California ;) Also I see UCSC is 
already at Coursera: https://www.coursera.org/ucsc

What I would really like to see in a course is testing getting in from the 
start. This so it becomes less a programming lesson than a how to design 
applications really well. TDD should not be the last chapter, but rather 
one of the first. Otherwise we learn bad practices from start, get lazy, 
write tons of bad code, just to see it blow up in our faces later with mad 
bosses and customers. I am guessing I have written a million lines of code 
that is really that bad until today.

Mostly many of us (read the guys/girls who does not have a CS degree) start 
testing because we finally realize that we have to, or that one of those 
two categories above forces us to do so. 

I really think it is incredibly sad that programming courses mostly skip 
these subjects, when well written code requires testing and systematic 
approach/following design recipes. For me it feels a bit like being in 
highschool just to suddenly find out that my math teacher forgot to teach 
me division all the way.

Web2py is already super simple to learn, so why not teach it with a 
systematic programming recipes and testing from the start? All the way 
trough. It would make the students think like engineers instead of 
tinkers/hackers/coders just randomly writing code to get "stuff" done. 
Doing this from the start does not make it more difficult to learn. It 
makes people solve problems easier because they can use a systematic 
approach to solving the problems. Having the systematic approach removes 
hassle of the code mess blurring out the learning task. 

Cheers!

[web2py] Request: Course about Web2py & TDD + pledge for cash

[Mika Sjöman]

Hi

I am trying to get started with TDD and web2py, but it is really hard since 
I do not have a CS degree. I have been studying this two courses at 
Coursera, and especially the former is awesome (I did not like the Intro to 
Systematic program design so much)

https://class.coursera.org/programming2-001/   # LTHP 
How to write quality code - awesome!
https://class.coursera.org/programdesign-001/class/index  #Systematic 
program design

I just wanted to say that if anyone out there is thinking of writing a book 
or video course, I would certainly pay for it! Preferably a Udemy course 
that shows how to do functional testing, unit testing, front end Selenium, 
integration testing, proper cashing techniques for fast webites etc. 
Preferably with TDD or some other framework, building lets say 3 to 4 small 
simple projects from scratch. 

I am really sick and tired of writing code that blows up. While web2py gave 
me an awesome way to easily write code and get going, I have not made much 
progress writing better quality code with web2py. I think too much time has 
been spent on learning to program (the language / frameworks), while the 
problem for me has always been not being able to do proper software 
engineering. 

So here is a pledge. If any of you good TDD programmers do a small video 
course on writing web2py software with TDD, Selenium, version control etc, 
then Ill be happy to chip in 50 USD for such a course. How about a 
Udemy.com course? Here is the guide to get 
started: https://www.udemy.com/official-udemy-instructor-course/
For inspiration about topics I really reccomend looking at that LHTP 
Writing Quality Code at Coursera. 


Anyone else interesting in pledging cash to learn proper software design 
with Web2py? Maybe someone can make it a kickstarter?

[web2py] Web2py and WebRTC?

[Mika Sjöman]

Hi

I would like the users of my website to communicate with video without 
using Skype etc. I am currently using pythonanywhere as my host, and they 
do not permit using node.js, so I can not 
use https://github.com/henrikjoreteg/SimpleWebRTC 

Is there any other way you guys know of that I could use to easily add 
WebRTC to the webpage? Anyone wrote a plugin for that? Anything I should 
know before jumping into it?

[web2py] Move from VPS to Cloud? Too big to pack

[Mika Sjöman]

Hi

I want to move my website from a VPS to Pythonanywhere. The problem is that 
my webpage has some houndred megabytes of video material so packing it just 
ends up in a python error "internal error: requested number of bytes is 
more than a Python string can hold"

Is there another way I can move from my Ubuntu/MySQL/Apache server to 
Pythonanywhere? Like a commandline packing and then pushing it with git/hg 
or something? Is there any pitfalls that I should be aware of? What are the 
steps? Would this work?

1. use HG of two folders; init folder and static web2py folder. Pull to 
local machine from VPS.
2. make a db backup of databases 
3. getting the DB backups to pythonanywhere. Any ideas on how to do this?
4. pushing the files to pythonanywhere? Not much a hacker, so any proposals 
on how to do this? I just know how to first pull and then push to the 
server I pulled from. 

Would this work?

Cheers

The typo there has not been fixed yet; 

use_janrain(auth,filename='private/dropbox.key') should be 
use_dropbox(auth,filename='private/dropbox.key')

But anyways, I got it working, but now when I try using it, I just get this 
error:

[web2py] Re: Error importing dropbox_account module

[Mika Sjöman]

a tip would be to include that reference into the documentation where you 
present the Dropbox API 

http://www.web2py.com/books/default/chapter/29/14#Dropbox-API

Found it with a google search, but still :)

cheers

[web2py] Re: Dropboxing movies into Web2py Server?

[Mika Sjöman]

Yes but how do I import the video into a field of web2py? 

I look in my app and it does not get inside my app folder - so where does 
it go? Say for example I download the movie via the Dropbox API, how do I 
then add it to my "video"
 table?

Cheers

[web2py] Re: Dropboxing movies into Web2py Server?

[Mika Sjöman]

Hi thanks for that dropbox info! Really helpful!

When it comes down to showing video at one side and presentation at another 
it is actually not so smart as people think. The brain has to take the 2D 
picture of the person and convert it to a 3D picture when it sees a face. 
Presenting material at the same time, overloads the brain and reduces 
learning (so it looks great but reduces learning). The great thing with for 
example Khan academy was that he took himself out of the picture and let 
students brains only focus on the material and his presentation. So 
video2py is not really for us. But thanks for the tip!

cheers

[web2py] Dropboxing movies into Web2py Server?

[Mika Sjöman]

Hi

We are trying to set up our production flow so that the guys making small 
instructional movies will automatically upload them to our server with 
dropbox. My question is how I can get those movies into a database 
automatically with the filename as the description into a 
Field('Description') of our videos table? Does anyone have an idea of how 
we can make somthing like this a reality?

I agree 

I think it confuses people allot who are starting with web2py since many 
try to use online themes, but they break because web2py uses an old version 
of bootstrap.

[web2py] can not migrate MySQL when deleting referenced field?

[Mika Sjöman]

Hi

Does anyone know how to delete a reference field from MySQL? I get an error 
from MySQL when I try to remove the field from the table 


 going from:

db.define_table('tecken',
Field('hsk_level',type='list:string'),
Field('streak_id', type='reference streak', writable=True))

### To:

db.define_table('tecken',
Field('hsk_level',type='list:string'))

This is the error I get:

 (1025, "Error on rename of 
'./dominochinese/#sql-7bc_b1' to './dominochinese/tecken' (errno: 150)")

Hi

I really badly want to get into testing because right now I have an

I would really like to get started with selenium but it seems so difficult

[web2py] Re: JQUERY as response in Ajax call?

[Mika Sjöman]

I was just thinking, would it not be smarter to have a FORM helper with an 
ajax option?

something like this:

FORM(ajax=True, eval=True, target='targetdiv/object')

To be honest almost half of my form posts are ajax now, so it feels wiered 
that I can not just choose if it is ajax when creating the form with the 
FORM helper. And the reason I do not do it more is because of the overhead 
and complexity of the code that increases for every form I need to write. I 
would even like to have a crud.create form that I could choose as an ajax 
form reducing ajax forms to a couple of lines of code in my controler 
instead of writing them in the view.

cheers and thanks!

that one worked like a charm. Final solution became like this, where the 
submit buttons is kind of there just for looks since it will send onkeyUp.

What I really like about it is that It reduces the JQuery to zero for my 
part to write which means less code to manage.

[web2py] jQuery and Web2py? Multiple vars problem

[Mika Sjöman]

Hi

I am having a problem because my forms are getting sent with multiple 
values. The issue is that on my page there are multiple places where the 
same formnames are used. So the post vars becomes like this:

Parametersapplication/x-www-form-urlencoded
answer280lesson75lesson75lesson75player_answer
quiz96quiz96streak7streak7streak7
Source
player_answer=&answer=280&streak=7&streak=7&streak=7&quiz=96&quiz=96&lesson=75&lesson=75&lesson=75
The above is created by>

jQuery('#add_quiz_option').submit(function() {
  ajax('{{=URL(c='quiz',f='add_inline_answer')}}',
   ['description', 'is_correct', 'quiz', 'streak', 
'lesson'], 'quiz_answers');
  return false;
});

On the server I could do a check if they are lists and then chop them down, 
but that is REALLY messy. Is this a design flaw from my perspective or is 
there a way to solve this better than renaming the vars and them renaming 
them to the matching corresponding database field names when the function 
receives the request.vars?

Starting to get really messy in my code now because I use ajax/jquery calls 
allot. I could rename the form names, but that forces me to rename them 
again after I receive them at the server. Is there a simple way to tell 
jQuery to only use the values from a specific FORM-name so it will not send 
the same value 5 times?

Cheers

[web2py] JQUERY as response in Ajax call?

[Mika Sjöman]

Hi

I am trying to close a window title dialog with JQUERY after sucessuflly 
updating a clients phone number. The problem is that after I successfully 
update the data I send this as a response to the browser: 


message = "jQuery('#windowTitleDialog').toggle('slow');"
return message


But the script just loads it as text in a DIV instead of executing the 
Jquery :( 

The way I call it is like this from the webbrowser:


jQuery('#update_phone_number').submit(function() {
  ajax('{{=URL('update_phone_number')}}', ['phone',], 
'phone_updated_div');
  return false;
});
 

Anyone has an idea on how to run the JQUERY instead of just loding it as 
text inside the phone_updated_div ?

[web2py] Re: Deploy to openshift

[Mika Sjöman]

Hi

I am sitting on a Mac and I have distutils installed because it works when 
I import it with python. But Web2py still complains that it is not 
installed. Any ideas? I tried to use the ez_setup, but nothing happens. 
Tried> sudo python ez_setup distutils, but I only get this then>

error: Could not find suitable distribution for 
Requirement.parse('distutils')

Any ideas? Cheers

[web2py] strange mobile behaviour when changing bootstrap theme

[Mika Sjöman]

Hi

I am trying to change the theme to the Cerulean theme at bootswatch.com. 
But changing from the default to bootstrap.min.css makes the web2py main 
menu go away when on mobile phone. Should I add / change anything else to 
make it work on mobile?

Cheers

[web2py] how about setting a standard fadeout to response.flash?

[Mika Sjöman]

Hi

Had a user pointing out how irritating it was that the response.flash never 
goes away automatically. Found this fix thou in the group, how about making 
a standard 4 second fadeout on it?

in web2py.js:

var flashBox = jQuery(".flash"), flashTimer;
  flashBox.click(function(){
  if (flashTimer) clearTimeout(flashTimer);
  flashBox.fadeOut(400, function(){jQuery(".flash").html('')});
  });
  flashTimer = setTimeout(function(){flashBox.fadeOut(400, function(){jQuery
(".flash").html('')});}, 4000);

[web2py] Re: update existing project model without breaking backward compatibility...

[Mika Sjöman]

Hi

Maybe you could dump it to a phone numbers to a csv file or a python dict 
with dump_data = { phone_number : contact.id,}

Then when you created the second table, just run a for loop to populate 
that table with the dumped data with contact_id as a reference to the old 
table.

Thats what I would do

// web2py rookie

cheers

[web2py] Free host for blog with domain?

[Mika Sjöman]

Hi

I wonder if anyone knows where I can put my we2py based blog up where they 
I also can use myOwnDomain.com for free? Not too much traffic, maybe a 100 
a day

And... I just build a community from scratch in two weeks from scratch with 
web2py, coming from django - I must say I LOVE web2py!

Huge thanks!

[web2py] IDE plugin what to use?

[Mika Sjöman]

Hi

I am totally new to web2py and thinking of skipping Django to get things 
done in Web2py instead. But - I really like working in an IDE if possible.

Is there any Eclipse web2py plugin - I find it quite messy to add headers 
for every controller manually. Learned about WingIDE but I dont like non 
FOSS software at all. 

Sincerely yours

Mika
