[web2py] Re: Modules Import Problem.

[Alfonso Serra]

Hi, im having a similar issue:

In modules, i have a utils.py module with a function called "first" that i 
cant import from another module.

The problem is that theres a utils.py module installed in the python 
standard library that obviously doesn not has that function and its being 
imported before my utils.py.

So the questions are:
- shall i modify sys.path so modules takes precedence over the python 
library?
- is there any drawback you can think of by doing so?
- where would it be a good place to do this?

I could rename the module to myutils.py and the problem goes away but still 
would like to load web2py modules first.

Thanks

Hi, so far it looks like this works:

sys.path.insert(0, r"E:\webdev\web2py-mod.02\applications\myapp\modules")

then im able to import as:
from utils import myfunc

Guys, I think you need to include the "modular" branch of pydal too:

git checkout modular

[web2py] SQL NOT IN issue(belong)

[Yann Dulondel]

Hi All 
Happy new year 2019.

I have an issue with SQL NOT IN
I tried to get a heater pad list(dropdown) in a form.
The heater must be related to user depot and not been used.
If they are used the heater id is set up in table articles

Queryheat=db((db.heatpad.id_depot==db.auth_user.id_depot)&(db.auth_user.id==
auth.user.id))&db(~db.heatpad.id.belongs(db.articles.heatpad))

I always get an exception memory error

Re: [web2py] modular web2py - need help

[Carlos Cesar Caballero Díaz]

I like a LOT the idea, my initial tests seems to work ok in Python 3.6.7 
on Ubuntu except the test_web ones are failing.


Tell me please, that one of the new year resolution is to have web2py in 
pypi :) That's something I would love to help make a reality.


This are my wishes:

1- pypi

2- The ability to:

pip install web2py
cd /home/myuser
git clone http://github.com/myuser/myapp.git
cd myapp
web2py run

And start my app. Something like this will make distributing web2py apps 
a lot easier (even using pip)


3- An advanced welcome app template, including .gitignores, tests, and 
environment configurations for development and production.


4- A more flexible grid:
There will be awesome if we could pass to the grid the template for 
rendering forms, or rendering buttons, cells etc... and define the logic 
for ordering fields (including virtual ones)


5- A CLI for applications, maybe using @cli decorators in controllers 
and maybe running them like "web2py --cli app/controller/function 
--param1=value1 --param2=value2"


6- A router that balances ease of use and power, maybe something in the 
middle of the two we have right now (I like the Yii2 framework routes 
style).


7- A more friendly error tickets for views (there can be difficult to 
find an error in a large view file), and maybe for reading them outside 
web2py (right now is really difficult to read errors accessing directly 
to the ticket files).


8- Some kind of "Modules system" that could make a lot easier the code 
reutilization.


With some guidance, I can use some hours/week and maybe include another 
dev for make this kind of features a reality. Even thougt I like the 
"web3py" idea, and I think that this kind of effort should be redirected 
to the new framework.


Greetings.

Thoughts?
Can you help testing that nothing broke in web2py?

[web2py] ajax controller loses formatting?

[Vlad]

I am sure I am missing something very basic here, but... googling didn't 
help...

When I have a contoller which I use in ajax calls, it all works just 
perfect except that the view loses the formatting (for example, it does 
keep the links and bullets - yet loses bootstrap formatting of everything). 
I don't understand why this happens and how to fix it. After all the view 
extends layout.html which does include everything, so why would it make a 
difference if html code is direct on the page or embedded via ajax? 

For example: the following 2 controllers via ajax produce exactly same 
non-formatted html:

def test1():
return XML("Home\
   #M1M2M3")

def test2():
return XML("Home\
   M1M2M3")

In fact, even without ajax, when I allow these controllers to go through 
default views (i.e. without having a dedicated view) - this is exactly what 
happens too, but here I sort of understand it - while in a case of ajax I 
don't, because ajax is embedded into real view html and should really 
pickup all the appropriate formatting which works well on the rest the 
page. 

What am I missing? How do I fix this?

[web2py] Re: ajax controller loses formatting?

[Anthony]

In order for an associated view to be executed, you must return a 
dictionary. If you return a string or HTML helper, it will be returned 
directly to the browser with no view being executed.

Re: [web2py] Happy New Year

[Carlos Cesar Caballero Díaz]

Happy new year!!

I have answered this in other thread because for some reason I have 
missed this one, and many of my wishes match yours 
https://groups.google.com/d/msg/web2py/BskHaFZkVEI/sudO0jdsFgAJ


First a question (mostly for curiosity). Why using Bottle instead (for 
example) Flask or werkzeug or one of the new async microframeworks? I 
assume because bottle is really small and we can include it without 
dependencies, and less verbose than werkzeug, but I have never used it, 
so I have no idea.


We can look in weppy most of the features that I really would like to 
have in web2py/web3py, it is in my opinion a great mix of flask and 
web2py styles. One of the things that I most like is the pydal based 
ORM. I know that there are a lot of people that like to work directly 
with the DAL, but in my opinion a ORM helps when we need to use 
inheritance and reuse code, and eases a lot the code reading in complex 
models. I really like the concept of "fat models and thin controllers", 
but my models looks really weird right now in web2py when I need to 
declare virtual fields or methods with complex logic.


I think that Weppy migrations are really useful in deployments and 
CI/CD, mostly when we need to make complex changes in database or 
update  old versions of our applications, because is easy to define an 
exact behavior of migrations and data.


Now some comments about your wishes:


4) the scheduler were part of pydal
I am not sure about this, of course you know the web2py API a lot better 
than me, and this have a reason, but I see the scheduler and the DAL as 
two completely different things, with different responsibilities, so I 
don't see why the scheduler should be part of pydal, instead of a 
standalone module.

6) we could remove every filesystem IO (errors, sessions, uploads)
But there should be an easy way for users to handle uploads, because is 
a common task.
8) auth logic were simpler and not tied to the current 
cookie/session/form logic.
I know that auth logic is a PITA, but still a lot of users use it. Even 
when use 3rd party services, is common to use some kind of authorization 
mechanism, so, I think that the framework should, at least, build some 
basic logic and an interface for extend or completely replace with 3rd 
party modules or custom auth logic.

9) SQLFORM and Grid were JS libraries that use Ajax for communication
That's good, but grid should be flexible enough, in my opinion, the main 
issue with the grid right now, is that customization is very limited or 
complex.
Then web2py -> web3py would be a thin layer using bottle and the above 
libs.


I think that there is a niche among Python web frameworks right now, and 
web2py -> web3py can fill it. There are a lot of microframeworks which 
are good, and fast, but need a lot of code and 3rd party integrations 
for building an application, there are others like django that include a 
lot of things, but still needs a lot of coding for building things like 
grids and forms or even a more classic app structure (that's why there 
are people making money with code generators), and there is web2py, 
which needs really little code for building applications, but is not 
"pythonic" or "flexible" enough fortake off between the developers. So 
in my opinion there is space for a framework which makes the developer 
life easier, and be "pythonic" and flexible, something like Yii2 or 
Laravel in the PHP world.


So, I think that, for really make a boost among python web developers, 
web2py -> web3py should aim to offer most of the features that web2py 
have right now, but with the flexibility that it lacks:


- It should be pip installable (and this is a must).

- Apps should be completely independents of the framework in the 
filesystem (no framework with applications folder, applications 
importing the framework instead).


- The framework should contain some pip compatible 
modules/component/plugin system which could extend the framework and be 
extended by the framework apps.


- There should be a recommended and documented way to write application 
tests.


- All framework components (or at least the public API) should be able 
to extended or replace.


Greetings.

PS: We should not drop off the current components. Really, is an awesome 
feature!! We should improve them.

[黄祥]

yes, you r right, previous error before is due to the lack of step i took 
- git checkout must run twice in web2py folder and web2py/gluon/packages/dal
- execute python (setup.py) must be in web2py folder can't be from another 
path e.g. web2py/gluon/packages/dal then python ../../../setup.py will 
produce an error

git clone --recursive https://github.com/web2py/web2py.git
cd web2py
git checkout modular
cd gluon/packages/dal/
git checkout modular
cd ../../../
python setup.py
python web2py.py
