Re: [web2py] Re: Webgrid so strange!

[Carlos Costa]

Well, now it´s working again.
The tip you gave was very valuable!

I went to confirm what encoding I have been working with because
recently I have changed from editor and was not sure.
It´s utf8 rightnow but I changed from ascii yesterday.

As it works now, I think that was actually the problem, my editor was
in ascii mode and now is in utf8 (right) mode.
Hope it´s only this.

Thanks, Mr Freeze!

The database wont be recreated.
And you could change the field name temporally.

I take this as opportunity to compliment the DAL.

Re: [web2py] Re: creating groups

[Carlos Costa]

You can create records and the the auth_group to create a group give a look
at it in the database admin, it is simple.

For example:
form = crud.create(db.auth_group)

with this line you can create a form where the user will insert a record,
so creating a new group.

To put someone in a group simply add a record in auth_membership.
Something like this:
form = crud.crate(db.auth_membership)

User must fill group and the user to add.

For setting preferences you can create another table that references a
group.
Put fields in this table for the preferences.
Something like this.

db.define_table('group_preferences'),
   Field('group',db.auth_group),
   Field('chat'),boolean), .. # other fields as
need
)

To verify if a user can chat with another you can do something like this:

can_chat = db(db.auth_group.user==userid_to_chat &&
db.group_preferences.group==db.auth_group.id &&
db.group_preferences.chat).select()
if len(can_chat) > 0:
  # if you got some record in the query the you can chat

Re: [web2py] Doubt in the example provided on web2py manual page 98

[Carlos Costa]

Probably you are confused because of this code present in index.html:

{{elif 'content' in globals():}}
{{=content}}
{{else:}}
{{=BEAUTIFY(response._vars)}}
{{pass}}

If theres no content it renders the BEAUTIFY(response._vars) just like the
generic view, so its not the generic view being rendered but a similar view.

Re: [web2py] refresh div in a html page (web2py)

What you get when you access the test2.html url in the browser?
Maybe the url is wrong.
Try to inspect using firebug in error console.

Looking the code above, elif is hit when len(rows) = 0.
So I am stuck here, how could it retrive any value if the lenght is zero?
Must look this whole code to understand it.

Re: [web2py] newbie : Accessing specific form elements' values from a controller.

[Carlos Costa]

I think you can do like this:

if request.vars:
   use request.vars.varname to access values
else:
  return .

Since you point your form to the right actions the all the vars will
be there when you submit.
When you dont submit they will not be there.

Re: [web2py] how to display data

[Carlos Costa]

First select the data you want to display

#select all records with all fields
articles = db(db.articles).select()

Second, pass it to the view
return dict(articles=articles)

Third, render it in the view inde.html
{{=articles}}

Note: this is the most basic data displaying with Web2py, you will
need to increment funcionality and design.

Re: [web2py] How to use XML data

You can do something like in http://web2py.com/books/default/chapter/29/5 :
Parsing

The TAG object is also an XML/HTML parser. It can read text and
convert into a tree structure of helpers. This allows manipulation
using the API above:
>>> html = 'Titlethis is a test'
>>> parsed_html = TAG(html)
>>> parsed_html.element('span')[0]='TEST'
>>> print parsed_html
Titlethis is a TEST

Re: [web2py] view with 2 forms

You will need to pass the post ID in the url or var or something.
And I think you want to show comments related to the post not another posts.

comments = db(db.comment.id=request.args(0)).select()

Pass this to the view.

Re: [web2py] fit image to shape

[Carlos Costa]

You will need an extra library to accomplish this, like PIL

Re: [web2py] Update query failing on GAE

[Carlos Costa]

Looks its a timeout.
Maybe I am wrong but you can state an update too many records. GAE has
time limitations, I dont know how much because I dont use it anymore.
Search for the GAE docs on these limitations.

You may try something like this:

 query = query | (db.asset_class.id == id)
requires = IS_IN_DB(query,..)

Re: [web2py] form.custom in modal window

Have you tested it without modal?
Just hit the url for mailVcard.load and make shure it works.
If if works you may have to debug the javascript using firebug for example.

Re: [web2py] How to run web2py on Linux Shared Hosting With No Shell, or SSH access

[Carlos Costa]

Have you asked your host for SSH access?
I have used hostgator, I have to ask then to grant me SSH access, and even
with this is a pain to make web2py run there.
If they dont give it anyway, consider change the host, give a try at
pythonanywhere.com, you should install web2py with one click.

Re: [web2py] Avoiding extra quries when using DAL

Maybe something like that.
You could do the query and save it as a dict and work on it.

result = db(db.table2.id > 0).select().as_dict()
retVal = [entity.name for entity in result]

 As mentioned, Web2py will run on your server and mostly deliver and

Re: [web2py] Can I do INSERT INTO statement with DAL syntax ?

I think it is not possible yet.
If you don't care about performance, in this case you can do it by code.
But if you care, use db.executesql...

[web2py] Re: web3py again....

[Carlos Costa]

Will it have default url routes?

beyond that,  my thought about ui widgets:
I think it would be nice:
1 - to have an easy integration via a model rest api
2- be agnostice to client side frameworks

Re: [web2py] Re: Future of web2py

[Carlos Costa]

Recently Google released official support to PWAs in Play Store.

So, if a web2py or web3py scaffoles ships with PWA support, it will be easy
to deploy it on web and Play Store
We would be able make web and mobile apps easily.

This technique is saving me hours and hours.

Re: [web2py] Re: Future of web2py

[Carlos Costa]

Untill this moment, for me, it means that in a second run, the app can open
instantly, mostly because of cached assets.
It does not mean that it will always partially work offline. It depends on
the need.
I think most apps made with web2py (and maybe web3py will be in the same
case) are dependent on server data and interactions.
Most data cannot be cached.
So it's my case.

One advantage of PWA is it being elligible for the A2HS (add to home
screen) funcionality.
Sometimes it is not viable for the user have installed a native mobile
version of a web app for long time, because the use is not frequent.

Basically, we need:
1 - a manifest.json
2 - icons referenced in the manifest.json, used to build the thome icon and
the splash screen
3 - a service worker js to be registered for the app, to be served at app
root. In web2py it is done with routes.py
4 - (optional) workbox to cache automatically all the app assets. (I
haven't got this working yet)

The first 3 steps are the only need to the browser display the A2HS pop up.

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.

[web2py] Re: new DBAPI in pydal for both web2py and web3py

[Carlos Costa]

Aweome!

I made a similar API for my apps, but is simpler.
I like this one more as it is more complete.

Mine is called Consult (because we call query as consulta in Portuguese)
This is very useful to integrate ui components such as datatable, or 
anything.

Maybe dal-api should be a good name.
If you want to use Consult, it is ok if it make sense for you, lol.

Re: [web2py] Need a developer. Seattle Wa

[Carlos Costa]

I guess it will be easier to find devs to work remotely for you.
Here in the group or even in ODesk for example.
Or if you prefer a local dev, you can hire a Django dev and ask him to
learn web2py.
He will find a very easy learning curve.

Re: [web2py] Re: Brazilian web2py users, what system do you use to receive credit card payments?

[Carlos Costa]

Pagseguro, for sure is the most used here in Brazil.
It belongs to UOL, it has a lot of advertising on TV.
Its the best know and trusted.

Another options are:
-mercado pago
-bcash
-moip
-braspag
-f2b
-paypal Brasil

I tried to sort them in an order of popularity.

Re: [web2py] AYUDA como ajustar la resolucion de la pagina de web segun el navegador ?

[Carlos Costa]

Mayra, esto es lo grupo web2py en ingles.
Por favor, reecriba tu question en ingles para que qualquier uno pueda
compreenderla.
Asi tenes mas chances de ser respondida.

Mayra, this is the web2py group in english.
Please, rewrite your question in english so anyone can understand it.
So you more chances to be answered.

The default layout.html already fits well and resizes itself when displayed
and smaller devices.
You can teste this by simpling resizing your browser window.
For me, it looks like you have a issue with your own css styling.
Maybe you need to redesign it avoiding fixed widths and heights.
Also give a look at the Bootstrap documentation, it is the css (and other
things) framework used now in Web2py.
Look how you can design your layout safely across different devices using
the appropriated classes.

Re: [web2py] 'Table' object has no attribute 'attr'

[Carlos Costa]

The book says in
http://web2py.com/books/default/chapter/29/07/forms-and-validators
"causes the hidden fields to be passed with the submission, no more, no
less. form.accepts(...) is not intended to read the received hidden fields
and move them into form.vars. The reason is security. Hidden fields can be
tampered with. So you have to explicitly move hidden fields from the
request to the form:

form.vars.a = request.vars.a
"

So I think you do not have attr field in the table activity, do you?

If so, you should do something like that:

values=request.vars
del values['attr']
db(db.activity._id == request.vars['id']).update(**dict(values))

Re: [web2py] Re: first() as aggregation function

[Carlos Costa]

I think he is looking for the first record of each group, not the first
record of the entire result.
I think there is no such function in web2py yet.

I have performed a similar task for reporting using this:
https://docs.python.org/2/library/itertools.html#itertools.groupby

It will require more computation and memory as you will have do it in
memory but is possible and simple.

Re: [web2py] OAuth - Can Users Authenticate without an Internet connection?

[Carlos Costa]

If they share the same DB and they all are in the same network, the builtin
authentication will work.

If not, you may want to sync the authentication tables while you have
connection. So each local application will have a copy.

Re: [web2py] Re: help with helper!

[Carlos Costa]

It is because you are using it the wrong way.

MENU helper itself generates the html marckup, ul, li, a, etc

Give a look at the documentation here
http://web2py.com/books/default/chapter/29/05/the-views?search=menu#MENU

Look that MENU has some optional arguments to setup the classes to custom
ones:

The MENU helper takes the following optional arguments:

   - _class: defaults to "web2py-menu web2py-menu-vertical" and sets the
   class of the outer UL elements.
   - ul_class: defaults to "web2py-menu-vertical" and sets the class of the
   inner UL elements.
   - li_class: defaults to "web2py-menu-expand" and sets the class of the
   inner LI elements.
   - li_first: allows to add a class to the first list element.
   - li_last: allows to add a class to the last list element.


But it always generate the same kind of structure:

>>> print MENU([['One', False, 'link1', [['Two', False, 'link2')

  
 One
 
Two
 
  


I you really need a different one, you should write it your own.

If your menus don't change do it hardcoded.

Re: [web2py] Re: TAG helper can not parse html

Yeah, the error is thrown by HTMLParser, TAG is build on top of it.
I will try some other tools like Beautifull Soup.

Thanks.

Re: [web2py] DAL Referencing By Name Not By ID Possible?

[Carlos Costa]

Give a look here:
http://web2py.com/books/default/chapter/29/06/the-database-abstraction-layer#Legacy-databases-and-keyed-tables

But I think it won't work in your case because name is a string.
Our you can model it another way.

db.define_table('tiers',
Field('name', 'string'),
Field('created_on', 'datetime', default=request.now),
format = '%(name)s')

db.define_table('metrics',
Field('tier_name', 'string', requires=IS_IN_DB(db, 'tiers.name
',%(name)s')),
Field('total_count', 'integer'),
Field('total_size', 'bigint'),
Field('created_on', 'datetime', default=request.now))

However, this will not enforce reference at db level, only in application.
But you can query an join it by name without problems.

query = db(db.tiers.name == db.metrics.tier_name).select()
metric = db(db.metrics.tier_name == 'name').select()

or you can obviously write a helper function to short it

get_metrics = lambda name: db(db.metrics.tier_name == name).select()
get_tier = lambda name: db(db.tier.name == name).select().first()

tier = get_tier(name)
tier_metrics = get_metrics(name)

Re: [web2py] requires IS_IN_DB set as a union of two queries

[Carlos Costa]

Have you tried something like:

query1=((db.vehicle.id==db.owner.own_veh_fk)&(db.owner.own_end_date!=None))

query2=(~db.vehicle.id.belongs(db(db.owner.own_veh_fk==db.vehicle.id
)._select(db.vehicle.id)))

query = query1 & query2

db.owner.own_veh_fk.requires=IS_IN_DB(query,'vehicle.id', '%(manufacturer)s
%(vin)s')

Re: [web2py] Re: requires IS_IN_DB set as a union of two queries

[Carlos Costa]

Sorry, I should have written:

db.owner.own_veh_fk.requires=IS_IN_DB(db(query),'vehicle.id',
'%(manufacturer)s %(vin)s')

If you need to pass a set so you need to call db(query) in order to execute
the query.

Re: [web2py] Re: How do I view text on view.html

[Carlos Costa]

I guess you need to familiarize yourself more with not just with web2py but
also with web development, right?

Anthony is right, you should read web2py book at www.web2py.com/book, at
least the first chapters to get a start.
At first you need to understand MVC.

For example you may have:

in db.py (Model)

class Person():
 name = 'Victor'

in default.py (Controler)


def index():

person = Person()

return dict(person=person)


in default/index.html (View)


{{=person.name}}

Re: [web2py] The Zen of web2py

I like it.

I wonder if we could do it in an organized in some way.

Recently I lost to convince my boss to change everything to web2py because
"there are few developers that know it".
So it would be very good to have a massive community. As we will have more
opportunities to work on the framework we love best.

Groups like this have little exposure outside. We need something else!

Re: [web2py] The Zen of web2py

I agree with you Massimo, the best ones are those that built something.
Videos like this http://vimeo.com/6782736 helped me to decide to stay with
web2py.
Not only that title is quite "marketish" but content is so true.

Re: [web2py] Accesing table from external database

I don't get it.
You can make DAL connection to SQL Server, what is the problem you can not?

Re: [web2py] Re: We could have something like this

[Carlos Costa]

It does not the same thing but it does.

It was intend to keep recipes, but one can post links to anything too.
Thinking this way it is even better than meteorhelp.

But the main difference I see is the dated layout, design and UX.
It is a nice tool but already needs a refresh.

 Is that a question? Are you asking if you can build a site like that? I
 don't see why not. In fact, instantpress almost meets your needs, though
 you might want to customize the theme a bit.

Re: [web2py] Translate Controller names and Function names

[Carlos Costa]

Very interesting question. It must have some effect on SEO.
I have seen this post but it does not seem to solve exactly this
https://groups.google.com/forum/#!searchin/web2py/translate$20url/web2py/3adXUSCGQQQ/TaKfRagHyvMJ

Although if you have a different URL for different content it will be
indexed.
If the two apps are working in two different domains they will be indexed
accordingly.

I tried to do what you want by interception the request object but it doe
not work.

One way is to use routes.py and write one rule per URL.

Re: [web2py] Re: Function being called twice from one button click

[Carlos Costa]

Use the browser console to investigate.
Look at the Network tab if it performs two actions with that URL.
Another thing that may sound stupid but it is not uncommon and I have
already seen it.
Some people double click buttons, icons in the web too.
I saw a case that a delay between clicks was need.
Another thing to look is the page delay. If it delays too much the person
may click again.

Re: [web2py] several vars in page

[Carlos Costa]

Question 1:
The parenthesis are wrong. The _href attribute is inside I and not A
helper. In fact, a parenthesis was missing too.
{{if page:}}
{{request.vars.page = [page - 1] }}
{{=SPAN(A(I(T('Previous')), _href = URL(vars = request.vars ) ) ) }}
{{elif len(rows) > items_per_page:}}
{{request.vars.page = [page + 1] }}
{{=SPAN(A(T('Next'), _href = URL(vars = request.vars ) ) ) }}
{{pass}}

Question 2:
If you are getting the following error: non-keyword arg after keyword arg
That is because you must always write first the "unnamed" arguments and and
the "named" arguments after.

 Massimo,

 On that note. I have seen some of that lecture and it seems very
 undergrad level. Is there a grad level course that you can offer where we
 can go through each API (or the most important one). Lets create few stand
 alone code and go line by line to understand how the framework is made? Get
 into more depth and complexity. Lets say someone is already a web2py
 developer but he wants to push the envelop and become an expert or even
 better (since no one can't clone you. lol). Is there a course like that?

[web2py] websocket messaging VS scheduler

[Carlos Costa]

I would like to use scheduler with a task sends websocket messages but it 
looks like they conflict with each other.
I am able to run only one of them.

If I start scheduler first, websocket freezes web2py.
If I start websocket first scheduler do not run any worker.

I start we2py with web2py.py -K app -a password -X -D15

In some action I do this to start the websocket

import subprocess
subprocess.call("python gluon/contrib/websocket_messaging.py -k mykey -p 
".split(' '))

but this freezes everything.

If I start websocket from shell manually both things work but I would like 
my app  to guarantee that things are running.

Some idea why this is not possible?

[web2py] How to read latin encoded characters correctly from MSSQL?

[Carlos Costa]

Whe I use pyodbc only, I can read and convert characters correctly.
But always replace accentuated characters with '?'.

I already tried the db_codec='cp1252' and db_codec='latin1' attribute in 
DAL.
In fact, MSSQL uses its own collation: sql_latin1_general_cp1_ci_as as 
collation.
But both latin1 and cp1252 work fine with pyodbc only by simply 
doing row[0].decode('cp1252') for example.

I also tried to use filter_out and SQLCustomType but they receive tha value 
already decoded wrong.

Any other thing may I be missing beyond hack DAL?

Re: [web2py] Re: web2pyslices

[Carlos Costa]

I'd like to help maintain it. And I vote for a web2py solution.
Not using would let us in a "shoemaker's son always goes barefoot"
situation.
I think this is embarrassing.

Re: [web2py] Re: web2pyslices

[Carlos Costa]

+1 for the web2py fiddle idea.
Maybe it could be run on an entirely Python sandbox. There are some libs
available to accomplish this.
