Re: [web2py] Re: RESTful service with access control

[Val K]

One yet important moment:
Do you set the view for your api?
I mean, that book example will not work without response.view='generic.json' if 
request is not local.

[web2py] block entire app

[lucas]

hey one and all,

where, in what model or controller, is the best place to place a few lines 
of code that captures every controller/function call in the entire app and 
returns a single page with a line of text and link to shuttle the viewers 
to another website.  and what would be those few lines of code also. 
 basically, how to gracefully shutdown an entire app?

thank you in advance, lucas

I just created a test app based on the code in the book and all is working
as it should.  Must be something else in my other app that is causing the
trouble.

I'll check it out later.  Also looking into JWT...

Thanks so much for the references.  However, I'm really a bit lost.

Using login_bare()??  Where does that come in to play?  And then a custom
decorator?

Am I doing something wrong that is preventing the sample in the book from
working?  Not sure why mine is just redirecting.

Any samples would really be appreciated.

Okay, I found the -t option, and from the web2py directory specified 
site-packages
Now, how do I get web2py.py to find the driver?

[web2py] setting up pscycopg2

[Dave S]

When I check Last week I ended up making the move to Postgres on the busier 
of my production servers, and the changeover appears to be successful 
(imported existing data via CSV).  I was interested to see that the import 
preserved some gaps in the id field, and that Postgres was filling some of 
those gaps and holding off on using id's above the imported max(id).  But 
I'm also getting errors about 'ERROR 23505, duplicate key value value 
viotlates unique contraint "updreq_y_pkey".  Key(id)=(23681) already 
exists.'

Looking at this made me realize I was running pg8000 (still supplied in 
contrib in 2.15.4), and I wanted to switch to pscyopg2.  So I tried 
pip install psycopg2

and that was progressing fine until it got to copying the built module into 
/usr/lib64/python2.7/dist-packages/psycogpg2 -- permission denied (not too 
surprising).  So I tired the obvious:
sudo pip install psycopg2
Which ends abruptly with 
[traceback excerpt]
The 'pip==9.0.3' distribution was not found and required by the application

When I check pip's version
pip --version
gives
pip 18.0 for  /usr/.../pip (python2.7)


and 
sudo pip --version
gives the 9.0.3 not found message.

What can I do now?
(AWS Linux, up to date, OS_VERSION says "2018.03")

It did until I install tornado , but still can't access the dashboard or 
any of the apps. 

 I am going to do a new git clone and try again.

Shoot, looks like my initial testing wasn't even working.  I was just 
checking the status code which was returning 200, but didn't realize it was 
redirecting me to the login page.  Any way i can stop that?

That error in the console is intentional. It is an example of what happens when 
there is a bug in app code. It should not prevent web3py from running. Or does

[web2py] RESTful service with access control

As far as I understand, basic means passing login and password in the headers 
and it doesn't matter if username or email is used as login, no?

[web2py] Re: Could this problem in production be related to web2py?

[Lisandro]

After doing a lot of reading about uWSGI, I've discovered that "uWSGI cores 
are not CPU cores" (this was confirmed by unbit developers 
, the ones 
that wrote and mantain uWSGI). This makes me think that the issue I'm 
experiencing is due to a misconfiguration of uWSGI. But as I'm a developer 
and not a sysadmin, it's being hard for me to figure out exactly what uWSGI 
options should I tweak. 

I know this is out of the scope of this group, but I'll post my uWSGI app 
configuration anyway, in case someone still wants to help:

[uwsgi]
pythonpath = /var/www/medios/
mount = /=wsgihandler:application
master = true
workers = 40
cpu-affinity = 3
lazy-apps = true
harakiri = 60
reload-mercy = 8
max-requests = 4000
no-orphans = true
vacuum = true
buffer-size = 32768
disable-logging = true
ignore-sigpipe = true
ignore-write-errors = true
listen = 65535
disable-write-exception = true


Just to remember, this is running on a machine with 16 CPUs.
Maybe I should *enable-threads*, set *processes* options and maybe tweak 
*cpu-affinity. *
My application uses Redis for caching, so I think I can enable threads 
safely. 
What do you think?

[web2py] RESTful service with access control

[Jim S]

Hi

I'm setting up a REST service that requires authentication.  I'm following 
the example here:

http://web2py.com/books/default/chapter/29/10/services#Access-Control

Here is the example with basic login:

auth.settings.allow_basic_login = True

@auth.requires_login()
@request.restful()
def api(): 
def GET(s):
return 'access granted, you said %s' % s 
return locals()

However, I'd like to use email authentication instead of basic_login.  

When I remove the first line, and pass proper email address and password, I 
get a 403 return code.

Anyone had success with a RESTful service using email authentication?

-Jim

[web2py] Python version in web2py console says 3.7 but 2.7 in the web console settings

I am testing OpenCV and need version 2.7 and that is what the site version 
says (2.7.12).
I updated the default.py for this new website and it failed due to the use

Whats up?

Re: [web2py] Re: Future of web2py

[Massimo Di Pierro]

I agree. About "tools that deliver apps to the client". I once experimented 
with this https://github.com/mdipierro/regift It is a cordova app that can 
be updated from the server without reinstallation. The app keeps the state 
and talks to server only if available. There is a lot that can be done in 
this direction.

[web2py] gluon.contrib.pymysql.err.Error AssertionError('Protocol error, expecting EOF',)

[Gilad Hoshmand]

Hi all,

I built a join query which breaks up a field that has '|' char as separator 
of values to multiple rows with single values (ie. field value = '1|2|3' , 
rows will be multiplied with single_value_field = 1 , single_value_field = 
2 etc..)
Filters some rows ('Having ... ' )
Then join with a table that I need to get values from.

I tested it on mysql 5.7 and it works fine.

I'm using db.executesql(...) to execute the query because I find it hard to 
make with the DAL but I'm getting an error.
The query is:

SELECT 
 *
FROM
(SELECT * , SUBSTRING_INDEX(SUBSTRING_INDEX(field1, '|', numbers.n), 
'|', - 1) AS single_value_field
FROM
(SELECT 1 n UNION ALL SELECT 2 UNION ALL SELECT 3 UNION ALL SELECT 
4 UNION ALL SELECT 5) numbers
INNER JOIN table1 ON CHAR_LENGTH(field1) - CHAR_LENGTH(REPLACE(field1, 
'|', '')) >= numbers.n - 1
HAVING (field1 IS NOT NULL
AND field1 != '||'
AND single_value_field IS NOT NULL
AND single_value_field != '')) new_table_alias
JOIN
table2 ON (table2.id = single_value_field)
WHERE (table2.field2 = '' OR table2.field2 is null)


My Error arises on db.executesql(...)  only when I include the last Join 
clause: 
JOIN
table2 ON (table2.id = single_value_field)

If it is omitted - no problems.

Full error(private bits renamed as in query):

Re: [web2py] Re: Future of web2py

[Carlos Costa]

I don't think all PWA cases must work 100% offline.
For 100% offline apps you just need a server to "install" your app, and so
web2py would be handy, but no more after install in client.
This is not case we should aim as web2py as focused on database driven apps.

Sync database may be desirable in some cases but no viable in many cases.
For most cases you want to cache a bit of data, like user data for example.
Think of a ordering or data collecting app, you may want to cache
items/products and also the order and sync it later.
For me this would be awesome but a little complicated.

My opinion is that for now if scaffold helped you to be eligible for A2HS
feature and cache static assets in client, it would be very helpful.

Re: [web2py] Re: Future of web2py

[João Matos]

You are correct. I though you meant keeping the app open and trying to use 
the database or loading another page.
In the case you close the app then you would need some kind of embedded 
server (as I already mentioned) or serviceWorker (which I think is 
something lighter but similar).

For the case where you don't close the app and only lose Internet 
connection and/or db connection you can check using JS. It was in this 
scenario that I meant any web app could do that.

I've increase number of applications connected to this service and then

Current;y I'm not sure is this only Chrome issue, the problem is that using 
DAL withput calling explicity DAL close method leave a lot of sockets in 
wating state on server side. I was able to reduce its number to 30 (from 
~300) adding excplicity call to close method and removing DAL connection 
for some requests which didn't need database (or I use my own db 
abstraction layer with close mthod called explicity on postgreSQL 
connection). From that point of view I'm pretty user that this issue is 
kind of DAL error.

Re: [web2py] Re: Future of web2py

[João Matos]

That is only checking if the Internet connection/db connection exists.
That could be done by every web app (web2py or otherwise).
That is not the definition of a PWA.
>From wikipedia
"
Progressive web applications (PWAs) are web applications that load like regular 
web pages or websites but can offer the user functionality such as working 
offline, push notifications, and device hardware access traditionally available 
only to native applications. PWAs combine the flexibility of the web with the 
experience of a native application.
"

Showing an error message is not the same as working offline (which requires an 
embedded server as I mentioned in the previous message) and the same goes to 
the hardware access.

Re: [web2py] Re: Future of web2py

[Martin Weissenboeck]

A few thoughts about PWA:

First: Web2py is great. But maybe the discussion should go deeper: how will
the internet be used now and in the future? It will probably be used mainly
by the mobile devices. With all the problems that arise from the fact that
the Internet is not available everywhere and constantly. And what do mobile
devices need? An exclusively server-side organized service can not do that.
We need clients to eliminate these bottlenecks - among other things, this
is the job of a PWA.

Web2py or Web3py could take over the management of the data. So, above all,
Web2py / Web3py could support the administration of the data and provide
tools that deliver apps to the client.

PWA clients include a lot of Javascript programs. In this model, Web2py /
Web3py should support the writing of Javascript modules.

The client also needs access to the data in the event of a lack of Internet
connection. Therefore, a local database must exist. PouchDB and CouchPB are
ideally suited to synchronize the local database at the client and the
central database at the server. Access to CouchDB / PouchDB could be
supported by Web2py. CouchDB and PouchDB work very efficiently with
predefined queries. This would require an extension of the DAL or a
separate library for CouchDB.

[Massimo Di Pierro]

Nice. But would you agree with me that this is mostly a client side 
functionality? Web2py and web3py are mostly serverside frameworks.
What would you want to see in web3py that helps with PWA?

[web2py] Re: Web3py

[Massimo Di Pierro]

Want to help:

1) need a version of this 
https://github.com/web2py/web3py/blob/master/applications/_scaffold/static/components/auth.html
 
with bootstrap style for forms
2) like for login and register, need similar methods for the other actions: 
https://github.com/web2py/web3py/blob/master/applications/_scaffold/static/components/auth.js
3) some of the backend logic is missing: 
https://github.com/web2py/web3py/blob/master/web3py/utils/auth.py#L40 (my 
next todo unless somebody beats me)

Follow the link then close the page, disconnect from internet and open again.  
Try to add/remove a todo item - you will get the alert 'Network problem'
