Re: [web2py] Re: Web3py

[黄祥]

scaffolding app would be nice to have example of authentication (user 
registration, login and logout) and to update the data, e.g. update todo 
list on todo app
just wondering, if form used manually using javascript, is the field 
validation on pydal, still can work ? e.g. requires=IS_NOT_EMPTY()

best regards,
stifan

Re: [web2py] Re: Web3py

[Massimo Di Pierro]

I have been looking more into veutify. I have some reservations.
I think a good CSS framework (for web3py) should be JS agnostic, even if 
the examples use vue.js. 
I think effects should be done in CSS only, not in JS. vuetify does not 
follow this rule.
Also vuetify is really designed for use with the CLI and I would like 
web3py to remain CLI agnostic.
Documentation is not good yet.
I think I will stick to bulma for now for the simplest example apps and 
dashboard.

For mobile app style, I like Framework7 a lot.

[web2py] Re: Web3py

[Massimo Di Pierro]

If you made use of SQLHTML forms and grid and simply want to move from 
python2 to python3, than stick with web2py.

If you want to use the DAL and maybe web2py templates but your app is (or 
will be) using mostly API driven then use web3py.

web3py already supports tickets (like web2py), pydal, yatl, helpers (almost 
identical to web2py), multi app (applications folder), and will soon have a 
functioning _dashboard (with similar functionalities to web2py's 
admin+appadmin). You will be able to develop and deploy and manage apps 
very much like you do in web2py. What we will not do, is encourage the use 
of server side rendering of forms and grids with postbacks logic that 
web2py has. We will instead create more tools to make API based apps easier 
to build with minimal JS programming. web3py will be less opinionated on 
the server but more opinionated on the client. It will not force you to use 
any client specific JS but default apps will ship with vue.js and examples 
based on vue.js.

The goal is the same "make web development easy and enforce good practices" 
but the web has changed since 2007, when web2py was designed.

Why do a redirect rather than simply doing the work in the same function? 
Also, this redirect puts the ids in the URL query string, resulting in the 
ultimate update being a GET request rather than a POST -- this is 
undesirable because a refresh of that page will result in the entire 
operation being repeated, which you don't want.

It's not that the function never gets called but that the function is not 
written to work this way. The function expects to find ids in 
request.vars.id, but that is actually None in the case where you call it 
this way (the real values are in request.vars.records). Is modify_price a 
controller action that needs to be accessible separately from this 
particular operation? If not, just make it a helper function that accepts 
an "ids" argument, and set selectable=modify_price.

[web2py] Re: Unable to edit grid record if I add @auth.requires_signature() to action. Is this normal?

[Massimo Di Pierro]

It is intentional. The grid requires a valid user to make field editable. 
You can override this with:

grid(..., user_signature=False)

In any case if the user is not logged if you tables require a user 
signature, those fields will not be automatically filled.

The SQLAlchemy ORM adds a lot of functionality that is not available with 
its DAL alone, and most of that extra functionality already exists in 
pyDAL. As far as I can tell, the weppy ORM does not really add any 
functionality to the DAL -- it is mostly an alternative syntax. I'm not 
saying there isn't value there, just that it is a lot of code maintenance 
to take on for maybe only a very modest benefit.

At least with the example given, I don't see a lot of difference in 
organization or readability (particularly not enough to warrant 
introduction of the ORM codebase as well as the confusion that can come 
with having multiple ways to do the same thing).

 Stage 2:  Welcome App -- seems to be problems with CSS, especially in
 the navigation bar.  Each menu shows up, but in faint blue on white, small

[web2py] Re: SQLFORM.smartgrid selectable return string or list

[villas]

Hi Icodk

I would see exactly what is being submitted by the browser. Open the 'web 
developer' section in your browser and look at the 'network' traffic.  When 
you click your submit button, see what variables etc are being sent.

If your function is really being called, then try some print statements to 
see what is being received by the function (you seem to be doing that).

Or, I guess you can also call your function directly from the lambda.  
...
selectable= (lambda ids: modify_price(ids, 100)),
...

def modify_price(ids, incr):
#print ids, incr
db(db.product.id.belongs(ids)).update(

product_price=db.product.product_price + incr)

web2.py existed before web2py and did not hurt us.
web3py existed before web3.py and in fact I own the domain name. It will 
not hurt us either.

I am more concerned by the confusion between web2py for python 3 vs web3py.
I am thinking it should have two names "web3py XYZ" where XYZ is t.b.d.

 https://github.com/nicozanf/web2py-pyinstaller . They now contain 
 python 3.7.3 64 bit. Also, the web2py sources inside the ZIP is now 
 replaceble with newer web2py versions when needed ;-)

 There is only a problem with the APP version of MacOs binaries, that is 
 not working due to this PyInstaller bug 
 . But the 
 MacOs command version works fine.


 Please, help my work by testing them! 


 Cheers,
 Nico

 Hi,

 I've just updated the experimental Windows binary version with 
 python 3.7.2 to web2py 2.18.4 . Also, now there is in addition the 
 no_console binary and there is the python-ldap module included. Grab 
 it 
 from https://github.com/nicozanf/web2py-pyinstaller : please test 
 it and give me a feedback.

 I'm still playing with the Mac version. Could someone confirm that 
 the current official binary version is really working? After typing 
 the 
 password I've got the error 'module object has no attribute pbkdf2 
 hmac' - 
 maybe for the python version included. According to this  
 
  it 
 should have at least 2.7.8 but it seems with 2.7.3.

 Cheers,
 Nico

[web2py] Re: SQLFORM.smartgrid selectable return string or list

[icodk]

Hi Antony

My selectable looks like :

selectable = [('Add 100 to price',lambda ids: redirect(URL('product', 
'modify_price', args=request.args, vars=dict(id=ids, inc=100,


and my function in the product controller looks like this:

def modify_price():

if type(request.vars.id) is str:

id_list = request.vars.id.split(',') #convertint to list

else:

id_list = request.vars.id

db(db.product.id.belongs(id_list)).update(product_price=db.product.product_price+request.vars.inc)


 Simply following the documentation in the book

I also tried:

selectable=  lambda ids: modify_price


But the function neve called

It should be request.vars.records, not request.vars.id.


Also tried with 

def modify_rule_end_time():

print request.vars.records 


and 

def modify_rule_end_time(ids):

print ids

But again no error and the function was not called

Re: [web2py] Re: Web3py

[villas]

I've just been playing with web3py and I think it's great!  This framework 
seems so much cleaner and I like the Bottle routes etc.

Re: Dashboard. Currently broken, but I guess Massimo is still working on 
this and committed prematurely.

Re: ORM.  It feels like we are talking about the icing before the cake has 
been mixed. Hopefully any ORM would just be a plug-in option rather than 
weighing down our fantastic DAL.

Re: Auth.  This seems a much more important topic because I'm not going to 
bother making any app until I know how to secure it. This is one feature of 
web2py that is vital.  I'm really hoping too that any auth would include 
'roles' because 'authorization' depends on that. I hope this will attract 
more comments.

Re: Form. I know that we want to be agnostic, but there seems little harm 
to include basic styling classes. Could this be taken from a config file?  
Maybe Vuetify would be better than Bootstrap?

Re: Grid.  I use SQLFORM.grid for prototyping,  but I then I so often find 
myself replacing that code with Datatables. Shouldn't we just include 
Datatables?  It has everything we need - doesn't it?

Thanks to Massimo and others for making this great progress for our 
community!
