[web2py:18507] MVC question
All, Just a question on the best practice - in terms of development continuous maintenance. web2py (like django) allows to define forms in controller itself. And it allows having 'business logic' embedded in views too. To bring out the application quickly, such mixing is fine. But what about long term maintenance and also to call the application truly MVC? What are your thoughts basis of your experience.

[web2py:18508] Re: MVC question
Let's look at what is meant by the term business logic --- this is what implementspart of a solution for a problem statement. If we were talking 4-tier model, then we would say business logic and engineering logic; it is the implementation in language of the solution/problem space, and just a further decomposition --- still implementation logic, still about the solution. With me so far? Now - what is presentation? It is how something is shown to the user. Does that require logic? Yes, it certainly can (consider javascript, etc.). What differentiates the logic of presentation form the logic of business? The concern, the type of processing. Is there some point at the boundary between these two where it might be fuzzy? Yes. How do you resolve that? You just make a choice, and do it however you choose. You'll probably do it differntly than I would. In the details, there's rarely a right or wrong - there's a better for this, or better for that. Back to this question about where do you define forms. What is a form? Is it strictly a presentation statement? Or is it a statement of required interaction with the user? Look: Business logic: we need name, address, phone to take an order Engineering logic we need input from user to collect name, address, phone Presentation logic: we want Name to be above address, address above phone - all on one form. Business logic: the customer may save his information with us, but that is not required for an order Engineering logic: persist name, address, and phone if requested (e.g. offer request to save) Presentation: Checkbox for save my info Now - where do you define form? It's a design decision - YOU decide. But some things are rather clear: validation logic probably should not be part of the presentation (although there may be valid reasons for this in your application) Defining color of form probably does not belong in the controller (better left somewhere else). Does it make sense to separate basic definition of an HTML form from the controller? That depends - are you going to allow input through PDF forms? csv? Then maybe it makes sense to separate this. If you're a web-input only application, then maybe not. By now you get the idea: some questions you can ask over and over, and get guidelines, and reasons behind them (e.g. color of form), but _most_ of these details are design decisions. Part of these are made or encouraged a certain way by the design decisions in the framework you choose to use; part of these will always be up to you, the software and web designer - what makes sense for one application will better be done another way; many things won't matter all that much... until you use them long enough, and then you will change your mind (e.g. refactor). mvc is just another way to say you've split your application into a data layer, a business layer, and a presentation layer - it's a separation of concerns; it serves to reduce design coupling. The goal is a maintainable and extensible app. The devil is in the details. Questions of truly MVC are like truly agile or truly capitalist / market economy or truly social --- as long as you don't loose the reasons behind these, why these abstractions (shortcuts to concepts) came to be in the first place, you're ok (otherwise you get into trouble): maintainable, extensible; frequent feedback; efficient, self-regulating allocation of resources in society; social responsibility to people in your community. :-) - Yarko On Tue, Mar 24, 2009 at 1:37 AM, Joseph Jude ceph...@gmail.com wrote: All, Just a question on the best practice - in terms of development continuous maintenance. web2py (like django) allows to define forms in controller itself.

[web2py:18509] Re: MVC question
I like the ability to prepare forms inside controllers. This really
makes difference from Rails, for e.g. And you get much cleaner View
code.
In controller you build your form and form processing code.
In view you place your form inside HTML as single {{=form}} statement
and glue javascript etc. So rationale behind MVC is preserved, but
with boundaries slightly shifted.
I personally prefer to build forms and menus in controller where you
have clean Python code, access to all functions, modules etc.

[web2py:18517] Re: MVC question
Yarko alredy explained this nicely, just one minor point to add - the MVC paradigm was not created for web apps. In a web environment, MVC, as a concept, cannot be strictly realized as a consequence of the http server-browser decoupling. Hence it's not a question whether a web solution is or isn't fully MVC decoupled, but rather which corner of MVC will you cut to fit technical and real life limitations. And this is where Yarko's argument comes in - it's about design choices, starting from the choice of the framework itself down to the location of form operations or helpers in your particular application. The bottom line is, don't let a pattern determine your project, but rather choose the best patterns based on your project's requirements.

the function 'add_records' is never called

[web2py:18520] Re: Full documentation
There is an effort to develop a comprehensive web2py wiki that is in its early stages. It's available herehttps://mdp.cti.depaul.edu/wiki The wiki right now is still pretty empty and doesn't look like approaching the coverage of the manual for a long time. So, would it be possible to kick start the documentation effort by allowing the copying of text sections from the manual? Clearly a lot of time was spent on the manual so it is understandable for a person to want to maintain ownership. However Massimo also spent a lot of time on web2py but still gave it away.

[web2py:18521] Re: about buttons
Yes, coz it cannot be called like this. The problem is not in web2py but
in your page. You have to use proper javascript call. So the result
should look like:
button onclick=window.location = {{=URL(r=request,
f='add_records')}}Crea attività/button
Then i think this will work as you expected.

the function 'add_records' is never called
while with
a href={{=URL(r=request,f='add_records')}}crea attività/a
then 'add_records' is called and works (I can see it because it
creates a file)
maybe is this the wrong syntax?

[web2py:18524] Re: Multi Column Unique Key, how to code best in web2py?
Yarko,
thank you for your support on this.
I was obviously not good in describing the problem well. Sorry for
that. Let me try to rephrase it from an different point of view.
Lets take the example code below as starting point. The tables shape
and color are working like needed. The problem comes with the
shapecolormonth table. The requirement in this case is to define a
table where the combination of the 3 fields [shape+color+month] must
be unique. For example a calendar which allows a 'red triangle' only
once every calendar months.
I kind of got into the direction (not completely, but until 2 row
column unique key) from the model layer side but lost the dropdown
selection in the viewer.
What would be the best way in this code example to get the multi-
column-key (shapename+colorname+month) unique while keeping the
dropdown functionality of shapename and colorname and the date
(widget) selection for the month ?
Side question: Is there a widget (-option) or another more elegant way
to select only the %Y and %m part of the date? The need to select a
day in this example is a kind of pointless since only %Y+%m should be
processed and part of the unique key. The widget return values are not
even passing the form requirements IS_DATE('%Y-%m') and hence the
before forced selection of the day part of the field would need to be
deleted manually to pass the form requirements. I'm sure you guys have
experience with more elegant ways to solve also that.
Thanks,
Hans

[web2py:18526] Re: under load
I will look into this error but you have an error into the _create function. This is called ONLY when a new table is created. Heavy or light load should not affect this since function is called only once. My guess is that you are editing the models in real time while the server is under heavy load. In general this is not a good idea because the migration can take long time, log the database until commit, and create too many database connections. Anyway. The error should not occur and I will fix asap.

[web2py:18535] Re: Qusestion about the book?
Hi Massimo, I can fully understand your motivation and will keep a fan and supporter of your baby. A different point of view could potentially be to use community contribution to drive/update/test the web2py documentation (the bleeding edge version) and use the community-tested (stable version) in consolidated fashion for print publication. When I remember right then Stefan Wintermeyer from Germany is using this approach with his book http://www.amazon.de/Asterisk-1-4-1-6-Installation-Programmierung/dp/3827326990/ref=sr_1_1?ie=UTF8s=booksqid=1237905177sr=1-1 while the 'open unstable' community version can be found at http://www.das-asterisk-buch.de Sorry that example is with German content only. But hey, doesn't RedHat support and use Fedora because of a similar reason. Yes I've to admit I'd love to see web2py scaling massively in adoption and I guess the community can and would love to help. Just my 2 cents on that.

If you are going production you will anyway be using a database that supports decimal Please add support for decimal :D On Mar 22, 1:19 pm, Paco francisco.c...@gmail.com wrote: All right, I knew about the implied decimal point solution but it won allow you to handle very big numbers. I made a quick check and only SQLite doesn't support DECIMAL types.

[web2py:18542] Re: Qusestion about the book?
I think a similar model is perhaps how Qt (the toolkit) does it. The references and basic tutorials are free, and of top notch quality. However, as the toolkit is quite complex, there are several volumes that delve on Qt and how you use it as a whole, how components interact and, in general, what good practices and the 'Qt way' are. http://doc.trolltech.com/4.5/ and the myriad of Qt books: http://www.amazon.com/s/qid=1237910608/ref=a9_sc_1?ie=UTF8search-alias=apsfield-keywords=qt4 So free docs, free software and copyrighted books can coexist in the same software ecosystem.

I do not make much money from it so that is not an issue. There has also been a lot of talk about the wiki, etc. I welcome this and I welcome more community effort nevertheless, different people want different things. If it takes more time for me to set-up and maintain things, I could as well spend the time improving the book.

Clearly a lot of time was spent on the manual so it is understandable for a person to want to maintain ownership. However Massimo also spent a lot of time on web2py but still gave it away. The wiki right now is still pretty empty and doesn't look like approaching the coverage of the manual for a long time.

I am not sure I understand what you want to do. If you name your app init, it will be the default app in web2py. If you unzip web2py binary, run it, create the init app, and re-zip it, this is as close as it gets to create an executable. The executable is web2py, not your app, but your app comes with it and starts when web2py starts. You can also install your init app bytecode compiled so that you do not give away the source code.

There is one more concept that is worth some words (although I don't want to turn this into a blog about mvc): Design coupling is an interesting topic - perhaps the best discussion I've seen on it was in Nam Suh's book Axiomatic Design (although I don't recommend that as a general design book - I think it misses some important points). Like pure MVC (or any of the other topics already mentioned) design coupling is the effect where, in order to change some part of a system, a dependent (coupled) part must also be modified. The worst of coupled design is that it results in a cascade of changes that in can (at very worst) be never ending, e.g. you cannot really make the desired change at all. A more functional version (!) is where to change some small aspect of a system, you must change many other parts of the system to accomplish your initial goal. So it would seem that decoupled design is desireable, and while the general concept is true, there is a very important point: There is natural coupling in all problem spaces, and you or constrained to respect that natural coupling in your solution - it is, after all, a part of the definition of the problem space. (Of course, you don't want to amplify it, or introduce additional coupling - and certainly not any unnatural coupling - that is, coupling that is not dictated by the problem space). So it is with forms: they are naturally coupled items: you want layout of input items, but they represent data you need to interpret and save - they are naturally coupled. And this is why forms seem confusing when talking about MVC - but, really, they're not. They are as they are naturally - they must be so. The biggest hurdle is to see that, and accept it in the correct context. There are other areas that accidentally introduce coupling - I ran into such an instance in web2py (actually, in the csv library) recently. It's nasty when you spot the coupling, and (of course) it will at some point be removed (the unnatural coupling, that is...) /end blogging Yarko On Tue, Mar 24, 2009 at 5:36 AM, AchipA attila.cs...@gmail.com wrote: Yarko alredy explained this nicely, just one minor point to add - the MVC paradigm was not created for web apps. In a web environment, MVC, as a concept, cannot be strictly realized as a consequence of the http server-browser decoupling. Hence it's not a question whether a web solution is or isn't fully MVC decoupled, but rather which corner of MVC will you cut to fit technical and real life limitations. And this is where Yarko's argument comes in - it's about design choices, starting from the choice of the framework itself down to the location of form operations or helpers in your particular application. The bottom line is, don't let a pattern determine your project, but rather choose the best patterns based on your project's requirements. On Mar 24, 8:22 am, Yarko Tymciurak yark...@gmail.com wrote: Let's look at what is meant by the term business logic --- this is what implementspart of a solution for a problem statement. If we were talking 4-tier model, then we would say business logic and engineering logic; it is the implementation in language of the solution/problem space, and just a further decomposition --- still implementation logic, still about the solution. With me so far? Now - what is presentation? It is how something is shown to the user. Does that require logic? Yes, it certainly can (consider javascript, etc.). What differentiates the logic of presentation form the logic of business? The concern, the type of processing. Is there some point at the boundary between these two where it might be fuzzy? Yes. How do you resolve that? You just make a choice, and do it however you choose. You'll probably do it differntly than I would. In the details, there's rarely a right or wrong - there's a better for this, or better for that. Back to this question about where do you define forms. What is a form? Is it strictly a presentation statement? Or is it a statement of required interaction with the user? Look: Business logic: we need name, address, phone to take an order Engineering logic we need input from user to collect name, address, phone Presentation logic: we want Name to be above address, address above phone - all on one form. Business logic: the customer may save his information with us, but that is not required for an order Engineering logic: persist name, address, and phone if requested (e.g. offer request to save) Presentation: Checkbox for save my info Now - where do you define form? It's a design decision - YOU decide. But some things are rather clear: validation logic probably should not be part of the presentation (although there may be valid reasons for this in your application) Defining color of form probably does not belong in the controller (better left somewhere
[web2py:18559] Re: jquery jqGrid JSON url problem
Hi Mike,
I am a web2py newbie and has to learn much from experts like you.
I would like to know which of the following url format you are using
to access your xml data in your server:
1. url: {{=URL(r=request,c='default',f='getjsdata')}},
2. url: '/EMIS/controllers/getjsdata.py',
Is it 1 or 2? Is it possible if you can email a source code of an
application
using web2py and jqGrid, I understand you are using jqGrid. I am also
very
interested to use jqGrid in web2py but not much documentation. I think
you
can provide the much needed example on this for everyone interested
in
this technology. Thanks in advance.

Hey Ed,
We're using jqGrid with XML data. Something thoughts (if you haven't
tried them already):
1.) Try your grid with the FireBug plugin for FireFox and look at the
response being returned to the grid. I've had web2py tickets thown at
that point and the only to see it is via Firebug. Or just check for
tickets from the admin app
2.) Did you set the response headers? in my case I had to
use...response.headers[Content-Type]=text/xml
3.) What does your controller look like? In my controller that serves
up the XML I just return a string with the XML data return xml
instead of return dict(xml = xml)
Hope that helps. I like jqGrid since it has excellent documentation
and hope more of us can make it work with web2py.

If you unzip web2py binary, run it, create the init app, and re-zip it, this is as close as it gets to create an executable. The executable is web2py, not your app, but your app comes with it and starts when web2py starts. You can also install your init app bytecode compiled so that you do not give away the source code.

Hi Massimo, freshmeat.net, icewalkers.com etc are very popular sites for listing software. They are just directories that redirect people to the actual project sites. Many of us in the IT usually start searching freshmeat, since the listing is marked by useful info such as licensing, latest released version, programming language used etc etc. This kind of listing will provide better visibility to web2py and should bring more users.
