I found the above script (and the corresponding configuration in the nginx 
config file) reduced my load time A LOT (didn't measure).

Thanks for having this kind of discussion.

[web2py] Re: Why do i have to submit the form twice in order to work?

[Alfonso Serra]

Thanks Annet, ill definitely will try, 

I was trying to get away without having to write formstyles, since i need 
control on the html output and it was a single post at a time.

I thought SQLFORM would be enough. but it isnt, ive hacked form.custom.end 
so it renders the right id and formname for each row but i still have to 
submit twice to fix the tokens. I understand why this happens. the 
controller expects the same form declared to be submitted, but with a table 
you cant know what record/form is to be modified beforehand.

So ye, grid or smartgrid it is.

Btw: im looking for an advanced course or teacher, cant find any on google. 
If you do teach please contact me privately.
Thanks

[web2py] Re: Adding class='hidden' creates an element style='display: none'

[Stuart Rolinson]

Perhaps breaks was a little strong, I should say it conflict with 
Bootstrap's .hidden class and causes problems with javascript being used to 
show and hide sections.

Thanks,
Stuart

[web2py] Re: Why do i have to submit the form twice in order to work?

[Alfonso Serra]

And this does work, which is very bad.

def example2():

rows = db(db.agencias).select()

#create as many forms as rows
forms = dict()
for row in rows:
forms[row.id] = SQLFORM(db.agencias, row.id).process()

fields = forms.itervalues().next().fields

if request.post_vars:
id = request.post_vars.id
if isinstance(id, list): id = id[-1] #get the id from the hidden 
field, not the record

form = forms[int(id)] #get the corresponding form

if form.accepted:
print "all good"
elif form.errors:
print "not good"
else:
print "welcome"

rows = db(db.agencias).select()
return locals()

This is bad since you have to query the db twice, and create as many 
SQLFORM instances as records, also bad.

Smartgrid and grid doesnt look like they fit my needs, ill keep reading 
about them but they expose several routes to edit a record when im trying 
to update them in a single view.

If i could use a dummy SQLFORM that passes a db.table validation of a 
random incoming post would be enough. ill keep trying. Thanks

Yes its wrong I'm sorry I didn't notice it. You got the order wrong. It 
should be:

Field('organizationID','reference Organization', requires = IS_IN_DB(db.
Organization.organizationPrimaryTypeID == 1, 'Organization.id')),

Re: [web2py] Re: SQLform grid custom function for delete

[Vid Ogris]

I am trying with something like this

links = [lambda row: A('',_class='glyphicon glyphicon

_href =URL('settings','deactivate',

But I cannot send vars to my controller function

I also tried with callback()

Any idea why?

I need to send id of the record and two static parametes e.g. 'tablename',
'tablefiled'

[web2py] Re: Self-referencing tables and queries

[Carla Raquel]

*So what? You should future proof the app. Some day there might be 
extensions in India or something.*

Actually, the extensions are internal to the company, either phone numbers 
or mobile numbers, so your scenario won't ever apply.

*Do you mean the extensions of the persons he supervises?*

That is what he already does, which is what I don't want it to do. I'll 
give an example,so that you can visualize it better:

Supervisor X has two extensions: 5589,5590
Supervisor X supervises two people: A and B
A has two extensions: 4572,4573
B has one extension: 4321

My current query returns: 5589,5590,4572,4573,4321
What I want it to returns: 5589,5590

Conclusion: Just the Supervisor extensions

Fine, I disagree with this assumption but I'm not your client.


> Conclusion: Just the Supervisor extensions

Well this is very easy, the Supervisor is just a Person like everyone else. 
So all you need is

# Assuming you're getting the id of the supervisor you want the extensions 
for in request.args(0)
supervisor =  db.auth_user[request.args(0)]   
supervisor_extensions = db(db.Extension.Person == supervisor.id).select()

Note, the first argument should be a Set, not a Query.

[web2py] Re: Why do i have to submit the form twice in order to work?

[Anthony]

No need for all this -- you can still use the method I proposed, creating 
just a single form (and giving it an explicit name). As you build each form 
in the view, just include a hidden "id" field and set its value to row.id 
(no need to use the "hidden" argument to SQLFORM, as you will be adding the 
hidden fields explicitly in the view).

"view" depends on the details=False argument
"add record" on the create=False

[web2py] Re: Is it possible to have this type of multiple requires in db.py?

[Anthony]

The first argument to IS_IN_DB can be either a DAL object (i.e., just "db") 
or a Set object (which is what you want). The second argument must be a 
field (either a field object or the name in 'tablename.fieldname' form) -- 
it cannot be a Query object, as you are using. So, you want:

IS_IN_DB(db(db.Organization.organizationPrimaryTypeID == 1), 
'Organization.id')

This is explained in the book 

.

You might also want to include db.Organization._format as the third 
argument, so the labels in the select element will be based on the "format" 
attribute of the Organization table.

Regarding your other initial attempts:

   - If you are going to use a lambda function as a validator, not that it 
   must take a Field object as its first argument and the value to be 
   validated as its second argument, and it must return a tuple, with the 
   (possibly transformed) value as the first element, and either None or an 
   error message as the second.
   - If you put IS_IN_DB in a list, you won't get a dropdown in forms. To 
   use additional validators with IS_IN_DB but still get the dropdown, instead 
   of putting it in a list, pass the additional validators as its "_and" 
   argument (also documented in the book).

Niphlod can probably provide better advice regarding managing scheduler

workers running ready to handle incoming tasks.

[web2py] SQLFORM grid, adding buttons

[Ron Chatterjee]

Is any reason that I don't see "add record" and "view" button with my 
sqlform.grid (like shown in the example 
here: 
http://web2py.com/books/default/chapter/29/07/forms-and-validators#SQLFORM-grid)?
 

When I use @auth.requires_login(). I do see the edit and delete button.


# db.py
db.define_table(
'members',
Required('name'),
Field('start_date', 'datetime'),
Field('Education','string'),
Field('work interest','string'),
Field('Telnumber',type='string',label= T('Telephone number'), length = 
64 ),
Field('Address','string'),
Field('Emergency_Contract_Name','string'),
Field('Emergency_Contract_Phone',type='string',label= T('Telephone 
number'), length = 64 ),
auth.signature)



#default
@auth.requires_login()
def index():
if_author = lambda row: (row.created_by==auth.user_id)
db.members.name.represent = lambda name,row: 
A(name,_href=URL('Our_Members',args=(row.id,IS_SLUG.urlify(name
grid = 
SQLFORM.grid(db.members,args=request.args[:1],editable=if_author,deletable=if_author,details=False,create=False,csv=False)

Re: [web2py] Re: web2py SPA(single page application)

[António Ramos]

I think you wont have that problem after 1.0


Unsafe delimiters for HTML interpolation can now be configured separately:

Vue.config.unsafeDelimiters = ['{!!', '!!}']
Note in 1.0.0-alpha when you set Vue.config.delimiters, it will still
implicitly update the unsafe delimiters following the current rules, but in
1.0.0-beta and above setting delimiters will have no effect on
unsafeDelimiters.

Would a computed field help with this?

>>> db.define_table('item',
Field('unit_price','double'),
Field('quantity','integer'),
Field('total_price',
compute=lambda r: r['unit_price']*r['quantity']))

>>> print r.total_price
9.95




In your controller, you would just return the form (instead of printing to 
the console), and on form.accept the total_price would now be displayed.

If you wanted to generate the total price as they entered the other values, 
you'd want to use Javascript to do the calculation ("onselect" or such).

 i used web2py with vuejs without a problem...


 for example i import my app.js  in my view to kick vuejs

 (function ($, Vue) {

 $(document).ready(function () {
 Vue.config.delimiters = ['(%', '%)'];

 new Vue({

[web2py] Re: Has anyone integrated user-driven multiprocessing?

[Niphlod]

The basic concept of the scheduler is to have a process (or multiple ones) 
NOT managed by the webserver, that are ready to do some work when told to 
do so.
Why ? 99% of the cases is composed by:
- long-running computations that will incur in the webserver dropping the 
process for timeout
- async processing of a task to make the webapp feel "snappier" while 
providing the same functionality

Starting an external process from a "web-served" process is a contradiction 
in terms: we don't want zombie processes and as soon as the webserver kills 
the "originator", the worker would be terminated too.
Another good reason to not provide that functionality is that one may want 
to run the task on a totally different server than the "web-serving" one 
(decoupling).
This is on top of the fact that managing long-running processes is best 
done by softwares specifically engineered to do so, and highly 
platform-dependant.
Given that starting those processes (and restart them if they die, etc etc 
etc) is fairly easy to set up with what the underlying OS provides, and 
that most of them are covered in the book, it shouldn't be hard to set up a 
scheduler.

That being said, the "scheduler architecture" relies on a never-ending 
process that loops over inifitely searching for tasks to be executed, 
sleeping when no tasks are ready to be processed. Every process is in 
charge of executing one task at a time, and the same task can't be executed 
at the same time by another worker.
In your case it translates to starting one - or a few - scheduler processes 
and to queue tasks from your application. As soon as a worker is ready to 
process those, they'll get picked up and executed.

[web2py] SQLFORM.grid and ractive

[weheh]

Anybody ever try to get an SQLFORM.grid(...) to render within a ractive 
template? I'm having trouble getting it to work. SQLTABLE works OK, but 
grid seems to bundle a script, which causes ractive to choke.

[web2py] Calling all Boulder, CO web2py users

[weheh]

*** Please reply to this thread if you're interested in a Boulder, CO 
web2py meetup. ***

Hello Boulder web2py users. I organized a very well received web2py meetup 
in Berkeley, CA, recently and would like to repeat something like it in 
Boulder, CO. Massimo has committed to attend and give a talk. The time 
frame would be in early winter because Massimo likes to ski, as do I. :)

I will volunteer a talk about designing and building sites with web2py and 
Ractive.js.

Anyone else is welcome to propose a talk.

I've spoken with the Boulder python Meetup.com organizers and they're open 
to having a web2py session, so let's do it!

What do you think? Want to volunteer a talk?

Im not saying better. I said favourite.
The docs are very good. Never gave ractive a chance because the docs were
not very appealing at first sight.
Only my opinion.

Re: [web2py] Re: web2py SPA(single page application)

[Massimo Di Pierro]

In vue.js there are unsafe_delimiters 
and they change automatically when you set delimiters. So I chose 
delimiters to e '{%','%}' and it automatically changed unsafe_delimiters to 
'{{%','%}}' so it was conflicting with web2py delimiters {{.}}.

I have zero experience with Radius, however there's no reason you could not 
make your custom login_method using an appropriate python radius client 
(I'm sure there are modules for that in pypi) check 
gluon/contrib/login_methods for examples of custom logins.
