[web2py] pagination previous and next on the controller
hi,
i've test the pagination from :
http://web2py.com/book/default/chapter/12?search=pagination#Pagination
and tried to change the next and previous that on view into the
controller
e.g.
from view:
{{if page:}}
a href={{=URL(args=[page-1])}}previous/a
{{pass}}
{{if len(rows)items_per_page:}}
a href={{=URL(args=[page+1])}}next/a
{{pass}}
into controller:
def list_items():
if len(request.args): page=int(request.args[0])
else: page=0
items_per_page=20
limitby=(page*items_per_page,(page+1)*items_per_page+1)
rows=db().select(db.prime.ALL,limitby=limitby)
if page:
previous = a href={{=URL(args=[page-1])}}previous/a
if len(rows)items_per_page:
next = a href={{=URL(args=[page+1])}}next/a
return
dict(rows=rows,page=page,items_per_page=items_per_page,previous=previous,next=next)
but returned an error, is there any solution for this?
thank you very much before
[web2py] differntial of request.args[0] and request.args(0)
hi, is there anybody knows the differntial between request.args[0] and request.args(0)? which better to be used on the application? thank you so much.
[web2py] Re: pagination previous and next on the controller
You don't put {{ and }} in controllers. Just do it like it is in the book.
HTML typically belongs in the view.
[web2py] Re: differntial of request.args[0] and request.args(0)
In the core chapter of the book I found this: In the above example, both request.args[i] and request.args(i) can be used to retrieve the i-th element of the request.args, but while the former raises an exception if the list does not have such an index, the latter returns None in this case. I would use request.args(0) and test for None if it is legal for the arg to not to be there on some requests. Conversely, if arg 0 is always supposed to be part of the request then request.args[0] would generate an exception and a ticket indicating a failure condition when it is missing.

Re: [web2py] Re: pagination previous and next on the controller
i've already tried to moved curly brackets {{ }} in the controllers and
still gettin an error, my intention is because all of my views is using
pagination and i want to simplified it to just put on the centralize db
functions.
is there any ways to do this?
thank you so much

[web2py] Re: default usage
It is simply how that record id will be displayed when used in a
foreign key.
e.g.
table colors:
id: 1, name: red,
id: 2, name: yellow,
table cars:
id: 1, descr: sport, color_id: 1
When you create a form for 'cars', how would you like the color_id
field to appear?
a) a drop-down box showing id numbers 1,2
b) a drop-down box showing red, yellow
Most people would say b). Therefore they use record representation to
enable this to happen automatically.

[web2py] Re: Class-based controllers and prefixes in wizard
Thanks all for the prompt answers! Massimo, I think that the flag in Wizard can solve the prefixes issue. Regarding the class-based controllers. pbreit, the components and the load function can help me in the composition, but can't help in the inheritance. Thanks for a good example, Bruno! I agree with you that domain specific logic must be located in the Model and Flow specific logic must be located in the Controller. For such case we need ORM in the Model, but we have DAL. OK, suppose we have created an ORM over the DAL. It will give me a possibility to inherit domain (model) specific logic. But I want to inherit work-flow logic too. Here is an example. Suppose we have a class/table hierarchy: Person-Customer-VipCustomer. Customer can Purchase something, Vip Customer can Purchase goods with discount and get a branded gift. 1. The case of class-based controllers: class Person(BaseController): def Create() def Read() def Update() def Delete() class Customer(Person): def Purchase() class VipCustomer(Customer): def Create() #define discount def Purchase() #purchase a product with discount and direct a user to a gift page def SelectGift()#select a gift after purchase 2. The case of function-based controllers: Person_Create() Person_Read() Person_Update() Person_Delete() Person_Create() Person_Read() Person_Update() Person_Delete() Person_Purchase() VipCustomer_Create() VipCustomer_Read() VipCustomer_Update() VipCustomer_Delete() VipCustomer_Purchase() VipCustomer_SelectGift() The functional case has 15 methods. In the first case there are 3 classes and 8 methods (more compact and readable). Why do I need to repeat some methods in the successors?

Simon, That is a good idea. In fact, almost the same approach is being followed in VFP cursor adaptor (the difference being that, data from MySQL tables is reproduced in same table structures, i.e cursors). Here, by virtual table, do you mean to say that we should reproduce the data into dictionaries by fetching a dict cursor from MySQLdb? (in DABO, they have an excellent concept of bizobj for this task). I am not asking for exact code, but can you suggest an approach to tackle the task?

[web2py] Re: show multiple tables in 1 page
That's why you would not usually structure it like this. Your index page is going to show all of the pages but then the comments for just one page. And as Denes points out, if someone just goes to /index, you're going to be missing a request.args(0). I don't really understand why you would set it up like this.
Re: [web2py] Re: pagination previous and next on the controller
You could check out this approach:
http://packages.python.org/web2py_utils/paginate.html
{{ }} *ONLY* work in views. The other thing you could consider if you want
to put it in a controller, model or module is using HTML tag helpers like
this:
if page:
previous = A('previous', _href=URL(args=[page-1]))

Now, with new web2py in trunk you can create this logic under /modules (as normal Python modules) in your controllers you will just need to instantiate your classes and work with inheritance, take a look the new global scope in trunk, now you can bind your db and other application specific objects as request,session, response in to a global object called current so you can access that objects in modules. I am doing some tests and I will use DAL to create my ORM too using the new importer and global scope. http://martin.tecnodoc.com.ar/default/post/2011/05/13/20_optimize-your-web2py-app-using-the-new-import-method -- Bruno Rocha [ About me: http://zerp.ly/rochacbruno ]

[web2py] How to apply a layout?
Guys, I'm certains this is very basic stuff, but I couldn't find an explanation to apply a layout from www.web2py.com/layouts to my app. I downloaded a file with w2p extension from there and I don't know how to use it. Please, send me a link because the book chapter about it doesn't touch about using a w2p file. Thanks. -- Vinicius Assef.
[web2py] Re: Multiple tables: update/insert/delete: in one form
Hi Vineet I'm sorry you didn't get a satisfactory answer, but I imagine there are group members like myself who would love to contribute but don't quite understand. Let's see if I got this right... You have a tricky form which might affect several different tables depending on which fields are completed? I see the data model, but what is the problem? Are you having difficulty writing some tricky logic into a controller? If so, what do you have so far and what is the issue? Maybe we could see the form?

In fact, almost the same approach is being followed in VFP cursor adaptor (the difference being that, data from MySQL tables is reproduced in same table structures, i.e cursors).

If the database has not yet been designed, perhaps reconsider. I still don't really understand what you are trying to do but 5 small tables might not be necessary. I would suggest getting some code working with 2 tables an then go from there. Some options:http://web2py.com/book/default/chapter/07#One-form-for-multiple-table... Another approach would to use FORM or SQLFORM.factory and then coding the database updates. You lose some of the Web2py features but it might still be the easiest way to do it. But my first suggestion would be to try and simplify what you are intending to do.

Re: [web2py] Re: show multiple tables in 1 page
Hard to say the best way to do it. This might be one way (not tested).
=== controller ===
def index():
pages = db(db.page.id0).select(orderby = db.page.title)
comments = db(db.comment.id0).select()
return dict(pages=pages, comments=comments)
=== view ===
ol
{{for page in page:}}
li{{=page.name}}br
ol{{for comment in comments if comment.page_id==page.id:}}
li{{=comment.body}}/li
{{pass}}
/ol
/li
{{pass}}
/ol
There's probably a much more efficient way to do it since the for comment
in comments loop goes through all comments for each page. The way you had
it didn't really make any sense because you were getting all the pages but
then just the comments for one (unspecified) page. db(db.comment.page_id
== db.page.id).select() is going to return ALL comments. If you want the
comments for just one page you would do something like db(db.comment.page_id
== r http://db.page.id/equest.args(0)).select().
To make it more efficient, you might be able to group the comments in the
controller. I don't know if this works, it's kind of a guess.
def index():
pages = db(db.page.id0).select(orderby = db.page.title)
comments = db(db.comment.id0).select()
for comment in comments:
comment_groups[coment.page_id].append(comment)
return dict(pages=pages, comment_groups=comment_groups)
ol
{{for page in page:}}
li{{=page.name}}br
ol{{for comment in comment_groups[page.id]:}}
li{{=comment.body}}/li
{{pass}}
/ol
/li
{{pass}}
/ol
