Re: [web2py] Re: web2py and python3

2017-04-02 Thread Alex

Is there any progress or at least a timeline when web2py will officially 
support Python 3?

It's 11 months since the last web2py release and I don't see much activity 
on github. So this is worrying me a little bit. I have a lot of web2py 
projects and I'll start a large project in a few months. I know web2py very 
well and it's a great framework, but at the moment I'm not completely sure 
if it's a good idea to use it for a new project...

best regards,
Alex

 web2py for python 3 would be great. I hope it comes rather sooner 
 than later. I'd love to use python 3, no more str <-> unicode nonsense

 (seems to have good support in PyCharm) and other new features. I 
 think the

 that web2py does not support python 3.

 pyDAL seems to be already compatible with python 3. Is it not 
 possible to make the remaining parts also compatible or are there 
 completely new concepts planned? I for one would completely remove the

Re: [web2py] how string_agg for groupby?

2017-04-02 Thread Alex

Is it possible to do more advanced queries (like using string_agg) with DAL 
in the meantime? Especially string_agg is very useful for efficient queries 
and I need it frequently. As it seems I have to use executesql which is not 
really what I'd prefer.

Are there any plans to implement such functions for DAL?

[web2py] Sites Powered by web2py

2017-04-02 Thread Alex

The section for "Sites Powered by web2py" does not look very promising and 
also seems outdated. Most pages don't have a screenshot and some of them 
are not even working anymore. When I try to visit the first site I get a 
link to an internal error ticket.

Submitting a new page does not work. We tried to add our website but it 
does not show up. Maybe you want to add it: https://breedarchive.com

Further I'd encourage you to completely restructure the powered by section 
because the current page probably has the opposite desired effect and 
scares off new visitors. Hundreds of applications, many of them with 
questionable content, is not really helpful. It would be much better to 
only show a very small selection (~5) of high quality web2py sites. Each 
one with a screenshot and a short description.

[web2py] best place to put style

2017-04-02 Thread Marlysson Silva

The first way is the best option because separate concerns ( views ( HTML ) and 
style (CSS) )

The second you are using all web page with componentes to include in current 
page.. I think that this is not a best pratice..

[web2py] IntegrityError('NOT NULL constraint failed:post.message)

2017-04-02 Thread Maurice Waka



I thought I had escaped/ solved this error. But now am stuck. My db.py code:

Post = db.define_table('post',
   Field('message', 'text', requires=IS_NOT_EMPTY(), 
notnull=False),
   Field('answers', 'text', requires=IS_NOT_EMPTY(), 
notnull=False), 
   auth.signature
   )Post.is_active.readable=FalsePost.is_active.writeable=False

controller:

@auth.requires_login()

def index():
db.post.answers.writable=False
db.post.answers.readable=False
form = SQLFORM(post, formstyle='divs')
if form.process().accepted:
pass
messages = db(post).select(orderby=~post.created_on)
...code
#after several codes in now need to post a message to answers field, 
WITHOUT using a form in the view page
db.post.insert(answers=report)

In my view:

{{for msg in messages:}}
code{{=msg.message}}{{report from answers field}}

My issue is that i keep getting the error: IntegrityError('NOT NULL 
constraint failed:post.message.

The two fields get data from different sources, post.message, from form in 
view and post.answers from a function in the code.

How do I solve this error? Kind regards
