Re: [web2py] Thanks for the awesome framework/setting up PostgreSQL
That slice is still works. The version number of postgres might be different, so instead of 8.3 use 8.4 or similar. You might also find things like auto_vacuum come set on by default in newer versions of postgres. Some of the web2py setup gets confusing at the end since I made some assumptions on how to configure the paths and used scripts the generation of apache config files. However by that point you could pick up at the book on enabling web2py through wsgi and apache. -- Thadeus On Wed, Jul 13, 2011 at 10:35 AM, Eric Scott erictransla...@gmail.comwrote: Dear Massimo and the rest of the dev team, You and your team have assembled a wonderful framework here. Coming from a PHP/CakePHP background (non-professional other than some work as a web designer in the late 1990s), I decided to switch to a python- based framework and spent the past week carefully researching options. After seriously considering Django, I ended up deciding upon web2py, first and foremost because it's clear that you and your team very publically stand behind your product. Thanks again for a wonderful tool -- it's much appreciated (and I just made a donation to the project to express my appreciation more concretely). I've started playing around with the framework on an EC2 instance, which is probably where I'll keep it for a small app I'm developing. I do have a question for the list: I'd like to set it up to work with PostgreSQL instead of SQlite. Is this the latest HOWTO on setting web2py up with PostgreSQL: http://www.web2pyslices.com/slices/take_slice/14 It looks like a very good HOWTO but I want to be sure it's current before I use it. I've got it set up on my virtual machine and I'm very familiar with SQL so it should not be too hard for me to set up the database; I just need recent documentation on setting web2py to work with it instead of sqlite.

Re: [web2py] Re: Using web2py's view/template engine in a standalone application
Yes..
You need some sort of response class that has a .write method... this can be
a hacked up cStringIO or other.
Alternatively you can perform the same thing manually by passing in writer,
which instead of the template engine writing ``response.write(%s)`` it
could write whatever you want as a callable function.
So for example, say you defined your ``CustomResponse`` class as earlier in
the list...
context['response'] = CustomReponse()
exec(parse_template(...)) in context
print context['response'].body.getvalue()
SO yeah... in the end if we implemented your suggestion of overriding the
response class on import, then the render function would work as expected.

Re: [web2py] Re: super in templates
Ah right, you can't have includes inside of blocks ! This is not a bug, just
a side-effect of how includes are implemented vs blocks.
I know understand the reasoning behind the str(t.content) patch, which was a
workaround to getting includes to work inside of blocks, but not the proper
solution.
It only worked because of the str(t.content) workaround, otherwise you were
not able to have includes inside blocks from the beginning.

Hi
I tried to figure out this problem more carefully and I found the
reason why my app didn't work anymore:
If the parent block contains {{include 'some_file'}} and view tries to
extend it by calling {{super}}, whole parent block will be ignored!!!
I don't see any error messages etc. This behavior has been changed
after version 1.94.6. The same code works in 1.94.6 but not in
1.95.1. Unfortunately I do not know web2py internals enough to figure
out what has been changed since!
Simplified test case:
controller function (default.py):
--
def test():
return dict();
--
view (test.html):
-
{{extend 'layout.html'}}
{{block content}}
this text will be shown in web page correctly
{{super}}
{{end content}}
--
view (layout.html): (stripped down, only relevant block is shown)
-
.
{{block content}}
this text wont be seen in web page if this block is
extended by calling super!
{{include 'test.txt'}}
{{end content}}
.
-
dummy text file (test.txt)
-
some irrelevant text to be included into view
-
If I remove {{include 'text.txt'}} from layout.html everything works
perfectly (text/code from the parent block will be included in
extended block). Web2py doesn't allow include directives in parent
blocks anymore!!

Re: [web2py] Re: problem with {{block}}s inside included files (v.1.95.1)
Take a look at the ``template.Content.__str__`` method, this is what is
responsible for flattening the tree.
Calling ``str()`` on any instance of Content effectively flattens it to
text, since there is only text in the parent tree, it has no knowledge of
any blocks that might have existed in the included tree.
The only point at which the tree should be flattened is at the very end of
the parsing when the entire tree is assembled.

Hello kasapo,

try figure out what has changed that broke and then we may be able to
revert the previous behavior.
So I have this structure:
bare (defines html, head, style, script (jquery includes), body
sections, and some containing blocks) -- ancestor to almost all
templates
right-col (included by bare, defines blocks which base will extend --
base extends bare, bare includes right-col so therefore base should be
able to see blocks defined by bare)
base (defines styles, background, etc -- the base template for most
things -- defines actual markup for blocks which are DEFINED in right-
col)
page (extends base, does not use blocks -- the menu rendered on the
page view is defined in base inside of a block that is defined in bare
via right-col include)
page-no-side-nav ( extends base, uses {{ block right-col }}{{end}} to
delete the right column )
Can you try:

Sadly, I am on RHEL and mercurial isn't present... so I will use my

Re: [web2py] Re: Error in templating system
I don't think you should have code included in a {{= block.
{{= should ONLY be used to wrap anything in its code block with a
response.write(). Exactly how it does it now.
Doing otherwise is simply bad template design. I consider it a bug if it
ever worked before. Allowing this syntax encourages template writers to do
things in non-standard ways that won't make obvious sense to anybody else
attempting to read their templates. (I currently have to maintain and
re-write some very ugly web2py code in my day job... the previous guys
working severely abused the power of the template system and it has caused
us many issues/headaches because of it).
tl;dr - it is the desired behaviour, update your app code to standards. lets
not complicate web2py further.

Right. The question the code has to answer, implicitly, is: exactly what is
the termination of whatever will be passed to response.write. If the =
doesn't appear at the beginning of a code block, the answer is: the next
newline, or the end of the code block, whichever comes first. I think that's
the right answer. It does mean that:
{{=msg abc

will become:
response.write (msg abc)
pass
...but I think that's OK; it's just a normal syntax error. It's really
too complicated to try to parse the argument, since you want things like
{{=abc def

to work.
I *think* that this will still work:
{{=string

Thadeus might want to chime in here if I have the details wrong (there
really ought to be a formal reference for template syntax; the tutorial in
the book is nice, but not complete).
There's a subtle difference in template parsing when =something
appears at the beginning of an escaped block (where beginning ignores
white space, so =XML above is regarded as being at the beginning of the code
block).
You probably know already that =something is translated to
response.write(something). But the question arises, what exactly is
something? That is, where does it end?
And when the '=something' is found at the beginning of a code block,
'something' is defined to be *everything until the end of the code block*.
When '=something' is found *embedded* in a code block (not at the
beginning, ignoring white space), then the end of 'something' is either the
next newline or the end of the code block, whichever comes first.
So (to shorten up the problem here), you've effectively got this:
{{=msg
pass}}
...which becomes:
response.write(msg
pass)
...and Python is going to object.
On the other hand, if you had written:
{{if xyz:
=msg
pass}}
The output will be:
if xyz:
response.write(msg)
pass
...and everybody's happy. Because =msg wasn't the first thing in the
code block, only msg gets included in the response.write argument.
Is there a good reason for =something to be interpreted two different
ways? I'm not sure it's intentional. Thadeus? Massimo?
Now I had to modify:
{{if msg:}}
h2{{=T(Commands executed)}}/h2

You could definitely use Jinja2 if you so desired, but honestly I do not see any reason why you would, you lose the ability to byte compile your views.

As far as the ORM vs DAL argument is concerned, it really depends on your situation. Firstly, I think the Django ORM sucks... if I were to use a python ORM it will be SQLAlchemy hands down. I think the django admin interface is just some fluff that is used for marketing. I know some people use it in production, but you can create a custom admin interface in web2py faster than you can hack the django admin do what you need it to do. I don't think it is a matter of syntatic sugar... there is a real difference in maintaining 70+ models in web2py vs SQLAlchemy... especially when these models need to be shared between external scripts. And for the situations... If you have alot of complex models that require many to many relationships and lots of joins... use an ORM, it is designed to handle complex relationships between records. If you have a few models, but lots of data that can be used directly... use the DAL, it is memory/cpu efficient. -- Thadeus On Wed, Jan 26, 2011 at 2:05 PM, Albert Abril albert.ab...@gmail.comwrote: Just for embroil more... ...is possible in some way to use django template system, or jinja2 in web2py?

Only the merits of the specific case before us matter, not how much support can be found for various options. To get web2py out of the PR's ditch, I think it's best to refrain from commenting on perceived weaknesses of Django and other technologies. Agreed. All we need to do is build great sites. And anyway, I don't see why we need to care about Django *at all*. Or any other framework for that matter. Why care? Focus on the platform available to us, i.e. HTTP (5?), CSS (3?), XML, Python (3?), and build the best web development framework for that. It doesn't hurt to consult the open literature (Django, Flask, Pyramid, Pylons, web.py, etc.), but the existing software is only a landmark on the route, not a stumbling block in the road.
Re: [web2py] Re: Why web2py? and not django?
That is just one of the very small reasons out of the entire haystack the advantages of an ORM are much too numerous to even begin to account I do not think circular references are a bad thing... it is a pointer after all... one thing I miss from C programming is the ability to control pointer vs. copy! SQLAlchemy does an amazing job at state management, and I have yet run into a situation where circular references could even remotely cause issues. It really depends on your application though. Use the right tool for the right job. The DAL has its advantages, the biggest of which is memory consumption and function calls when querying large datasets. An ORM will grow exponentially in memory usage as you add more objects. The DAL keeps a linear memory growth as expected, so when you need lots of data its very efficient and the effects can be noticed even with as few as 5000 records. It also depends on the programmer. I had OOP concepts ingrained from the beginning (Java was my first programming language I learned)... so obviously SQLAlchemy would feel much more natural to me. That said, I actually do use the standalone DAL in some scripts that process data for my app that has 73 models (it used to have 50, but I have been busy the last couple of months). The reason is because for batch processing analytics for some of my tables, the DAL is the right tool for the job, and using an ORM makes the process take about 2-3 hours as opposed to 30-45 minutes. -- Thadeus On Wed, Jan 26, 2011 at 3:40 PM, VP vtp2...@gmail.com wrote: . there is a real difference in maintaining 70+ models in web2py vs SQLAlchemy... especially when these models need to be shared between external scripts.

Re: [web2py] Re: ADVOCACY: every single other Python program ever written uses imports?
I believe this is why web2py receives much criticism. I speak from experience in using (and contributing to) web2py. web2py cannot share objects in an importable namespace with other python applications ecause of its design architecture. This is an absolute requirement for most enterprise or real world applications. Two examples. (however there are many more than I have time to iterate over) Exhibit A: Multiple websites that share some or all database models and utility functions. A public site may use only some of the models needed for say user signup, and a dashboard that may be IP restricted for internal use only. Exhibit B: Must share database models with stand alone python programs. A long running process that sits in the background, but needs access to the database. web2py cannot do either of these, and unless web2py uses import it will never be able to. Currently, to accomplish exhibit A or B, code spaghetti-fication must occur, and maintainance of model definitions in multiple places now becomes a royal pain in the ass. That or you must use some of the other many (unprofessional, hard to maintain) hacks just to work around this limitation. With other frameworks, such as flask/sqlalchemy it is a python program like anything else. You can do from dashboard.models import person. You only maintain one model, but you can use it in all applications that may need it, since you can easy_install your site into a virtualenv. Another issue that I have ran into more often than not is the limitations in the web2py core. Certain things (like SQLForm, auth, sessions, etc) are great for rapid prototyping, but when you actually need to do something real with them, they just get in the way. For example, a form that has a subform or a built in subtable (like a form you might build in Access), or cookie stored sessions for scalability. Again, these are just simple examples when the real world implementation is much more complex. Another problem that the current design of web2py inherently brings is it enforces a functional programming style. You can use classes, but then you end up having to throw pointers around of your basic objects (db, session, etc). Using classes the way they are designed to be used with a normal object lifecycle (imported, instantiated, etc...) is extemely difficult to do in web2py. There is nothing wrong with functional programming, but the code can easily become a mess even if you are a good programmer. Just to give an example of how amazing a class based system is, I re-wrote appadmin for Flask+SQLAlchemy+WTForms in 80 lines of python code, with pagination, searching, creating, updating, and deleting. Think of how maintainable that is. I don't even know what is going on inside of web2pys appadmin... I try to stay away from it *wink*. One of the biggest arguments vs other frameworks is the speed of development time of a web2py app vs other framework. I disagree with this, I am usually able to add new features to my flask apps much faster than I can in web2py. This is probably due to the simplicity of other frameworks and not having to fight with anything being pre-determined for me (such as database tables forced to lowercase). As long as all your doing is building a simple website that will be completely 100% self contained into web2py and it isn't expected to grow over 10K lines of python code, web2py is great. If you are doing something that requires code to be shared, and has lots of complex models and a large codebase that will need to be maintained by other people than yourself in the future... I would pick Flask. I speak most of this from real world experience. I work in both web2py and flask every single day and know the strengths and weaknesses of both.

Re: [web2py] Re: ADVOCACY: every single other Python program ever written uses imports?
I think Massimo hit it on the spot. Its about coding style. Most of the people I see giving web2py criticism are young. Considering that beginning in about 2001 colleges starting only teaching java and handing out degrees, it might be safe to assume that most of these guys knew Java as their first language. Not to mention that someone who went to school for 4 years for software engineering will have been uniquely tuned to a specific coding style (object oriented). I like web2py, and I do have uses for it on a daily basis to accomplish real world work. I use web2py alot to provide a web based access to automating statistical analysis. Usually these type of apps need to change often and can even change drastically, which is why I like web2py for them. -- Thadeus On Sun, Jan 9, 2011 at 1:46 PM, VP vtp2...@gmail.com wrote: I think web2py is very good for 'Corporate' and 'Enterprise', but perhaps we need to be less pretentious and change the slogan for something like: web2py - the getting things done web framework I know much less about web2py than most people here, but I feel compelled to add an opinion. There are many different things that are touched upon in this thread. First is the slogan of web2py. I think the word enterprise is a mistake. But at the same time, the attacks that center around this word is very unjustified. For the sake of comparison, let's take a look at the Django's slogan: Webframework for perfectionists with deadlines. Now, you can easily attack this slogan in much the same ways people have attacked Web2py. But most people don't do that. Massimo is not great at PR, so his PR approach is easily prone to attack. But at the same time, a slogan is just a slogan. And yet people unfairly focused on a little slogan repeatedly. That's utterly unfair. Second, let's talk about what it means to be enterprise. I think a many people tend to make this type of reasoning: (1) I am doing real work, (2) this tool isn't quite the best thing for this work, (3) therefore, it is not real (enterprise). I do not agree with this line of reasoning. A tool, any tool, has its limitations and within its boundary of effectiveness it can be as real as any other tool. Drupal, for example, has been used extensively in many big companies to do real things. And yet, Drupal, at its heart, is a CMS, and therefore is not as flexible as something like a webframework. As such the domain of effectiveness of a CMS is smaller than that of a webframework. But when people need to build CMS, Drupal is very effective and *real*. The right word, I think, is generality. A full stack webframework like web2py is more general than a CMS like Drupal. Thus, it can do more things. Something like Flask is not a full-stack framework, as such, it makes fewer assumptions, and it is more general than a full- stack framework. At the same time, it doesn't have as much batteries. And many will find a full-stack framework more useful in that regards. So to say that because you can not import pieces of a model into an app, therefore web2py is inappropriate for enterprise, is not right. I think many enterprise apps do not have to have highly connected models. There are many other dimensions that are important with respect to what it means to be enterprise, such as scalability, maintainability, etc. And I think that web2py still needs to be proven in this regards. And third, there's a criticism that the internals of web2py is a mess. That might or might not be true. There are a few things I'd like to say in this regards. First, from a user's point of view, this criticism is not very interesting. But this criticism implies indirectly a few things, such as there are many bugs; or it's not easy to add features to web2py. From an outsider's point of view, this is what I see. In terms of man power, web2py has fewer than Django. I think Flask also has a decent number of developers working on it. Web2py has mainly Massimo, who wears many hats; plus maybe 2, 3 other people putting a lot of time into it. And yet, you look at features, there's not much Django has that Web2py doesn't have. Another thing that adding features to Web2py is quite quick. This is what I often see around here. When someone has an idea, Massimo often does it right away. Recently, it took a relatively quick effort for Massimo (and probably a handful of other people) to rewrite DAL completely. Now, going back to the criticism that Web2py's internal is real bad. I am very reluctant to believe that is the case, given all of these I have seen and experienced around here. Having said this, I don't think I am a web2py zealous fan. Trust me, if there are better frameworks, I'd jump in a second. I have perused the Flask/Bottle/Django documentations countless of times, and each time, I just decided they do not yet have what I want. Further, there are a few
Re: [web2py] Re: Can any help me with new dal in trunk?
All I know is that tables are issued as lowercase, but you can still access
your table as an uppercase attribute.
There is an inconsistency in the DAL somewhere because of this... Somewhere
it is forgetting to convert to lower case. I don't know why converting table
names to lower case is forced in web2py and I disagree with it.
for example:
db = DAL()
db.define_table('TableA', Field('Superman'))
# CREATE TABLE tablea WITH FIELDS superman
db(db.TableA.Superman == clark).select().first().Superman
# SELECT * FROM tablea WHERE superman=clark

It is a good balance between new features and the ultimate stability of release 1.XX.N where N is the last version before XX+1 for example. The nightly build is a bit of a misnomer, many projects (C or C++ mostly) have some automated process that takes trunk and compiles it to produce a .tar.gz labelled nightly which might work. For web2py we should just hg pull; hg update to achieve that result. The nightly for web2py is more like a beta because Massimo hand picks code from trunk that will or will not be in the nightly which could really be a weekly. I am currently developing the application I am working on and testing is easy enough that I test trunk at least daily. The web2py server is quite easy to use but the code in some places is complicated and has many possible use cases. It is only through exposure out to the user base that a large number of use cases of the code get tested. I have even seen problems reported where something was fixed but used by maybe one person in a way that should not have worked resulting in the dreaded bug that worked and became a useful feature for someone. Once I go to production I will probably move the releases a lot slower through the installed base. In fact I have 2 beta production systems up now and only push a new web2py when I push a new version of the application to the stakeholders to look at. Massimo provides a fantastic service with the web2py project and I would not like to see him stifled by a load of process. Anyone that has time to test will definitely help the quality, if you don't have time, that is okay too. I personally don't mind doing some release management between where Massimo is burning the midnight oil and what I let out into the production systems I have/will manage.

This protects your page from html injection hacks. If you need to display

Good. Now this thread can go into the list of many archived threads about this topic. Nothing will happen and things will continue as they have been, which isn't so bad because nobody is forcing you to upgrade your web2py version each time a new release comes out. However, Branko, part of the problem that nobody else can even perform basic release management. Nobody but Massimo has access to trunk, and therefore nobody but Massimo can make releases, create branches, maintain stable etc. This leaves the project in a odd state that the only thing that can be done is to complain.

Storing sessions in encrypted cookies makes a each request 1-2ms faster by trading bandhwidth (required to communicate the session in cookie) with file IO (required to locate and access the session in a file). Scalability-wise sessions in files do not present a problem as long as one uses a load balancer with support with sticky sessions. On common problem arises when there are too many session files in the same folder (the os becomes slow accessing the folder). This problem has been solved in trunk last week by creating a sub-folder tree structure for the session folder. Session in files some advantages of sessions in cookies: they can contain more data. They can be controller server-side (checked, deleted, modified). They can be locked to force per-user serialization of form processing(default in web2py). Bottom line: current sessions are not a scalability issue but it would be nice to have the option of sessions in signed cookies. It is not difficult to do and we have it by the end of the year. This will be a major speed up for system that do not have a filesystem and currently require storing sessions on datastore, like on GAE.

Re: [web2py] Re: How could I send a email to every members?
the problem with mail.send is it creates a brand new connection to the SMTP
server *every* single time you call it.
If you are sending more than 10 emails at a time this will not be efficient
and will take an unnecessary amount of time to complete.
I would suggest dropping down to using base smtplib so you can send
everything through a single connection. Keep in mind when doing this certain
SMTP servers have limits on how many emails can be sent (500 by default) so
you would need to re-establish your connection after this cutoff point.

Jose. 2010/11/14 mdipierro mdipie...@cs.depaul.edu I agree that there are things we can improve in web2py. Yet, if a complex application have many pieces that are untangled, the import mechanism does not necessarily help you. The solution is trying to design components that are relatively independent. If you can do this, web2py does not bet in the way. For example, you have 100 tables functionally grouped in ~10 and all they need to share is authentication, you may want to separate the functions in 10 different web2py applications (all sharing one database, each defining only the tables it needs, and sharing one session cookie). This modular design solves lots of problems. I have heard of people who have developed complex applications in Django (which uses the import you suggest) and run into problems because they were using more ram than needed since all modules were always imported. In web2py controllers are executed only when called and if you make many small controllers you save lots of memory. Controllers than then import the modules they need and only those.

The approach of multiples apps sharing same database is useful, but how could we solve the division of tables in apps, is it better to define the model in one place and import the required tables on the apps? Jose. 2010/11/14 mdipierro mdipie...@cs.depaul.edu I agree that there are things we can improve in web2py. Yet, if a complex application have many pieces that are untangled, the import mechanism does not necessarily help you. The solution is trying to design components that are relatively independent. If you can do this, web2py does not bet in the way. For example, you have 100 tables functionally grouped in ~10 and all they need to share is authentication, you may want to separate the functions in 10 different web2py applications (all sharing one database, each defining only the tables it needs, and sharing one session cookie). This modular design solves lots of problems. I have heard of people who have developed complex applications in Django (which uses the import you suggest) and run into problems because they were using more ram than needed since all modules were always imported. In web2py controllers are executed only when called and if you make many small controllers you save lots of memory. Controllers than then import the modules they need and only those.

Re: [web2py] Re: DAL() unusable ?

Is there a reason for not sticking the record creation inside of its own table? -- Thadeus 2010/11/12 Mirek Zvolský zvol...@seznam.cz hich person is an employee of which company, 2) which person has created the company record, 3) which person has created the person records, all 3 relations are 1:m relations. To realize 1:m relation there is no need to add a connecting table and if you do so, that would be a realy very bad design ! And it's easy to say why in other words: Because in case of real m:m relation there can be more as one records in the added connecting table to describe relationship between two entities. But if you will add connecting table from your weak reasons, then you will have always one(!) record in the connecting tab
Re: [web2py] Re: DAL() unusable ?
Your error seems to be coming from the fact you do not have defined a person
model. Since web2py is a functional designed you must define person table
before you can reference it.
I use the following self-referential table and have never had a problem.
db.define_table('participant',
#... lots of other fields
Field(referred_by, reference participant),
#... lots of other fields.
)

Here's a link to the section in the book:
http://www.web2py.com/book/default/chapter/06#Self-Reference-and-Aliases
Yes, I know this, and from that reason I always use 'reference..'
style syntax.
However this is about very special foreign keys, which targets to same
table (to the primary key in same table).
And if there is some cycle in joins in the model (and of course it
always is, except of very, very simple models), this will not help.
And there is realy no solution for this in web2py ??
Re: [web2py] Re: Pagination [Web2py Utils] returns None
There are two alternatives. Have the generate_links function assume args when creating the url. This could be based on the existing args in request. URL(r=self.r, args=self.r.args) Or patch get_set to allow passing args as part of the function declaration, it would in turn pass these args to the generate_links() function and then URL would use those args. In the first case you would not need to change anything on your side. The second option would look something like qry = paginate.get_set(set_links=True, args=['myarg1', 'myarg2']) Which would YOU prefer? -- Thadeus On Thu, Nov 11, 2010 at 3:09 AM, Andrew Evans randra...@gmail.com wrote: ur the developer of Web2py Utils is that corr

Database 101, any many to many relationship must be defined through a link

Redesign CR2 like so...
db.define_table('person', created_by('person'))
db.define_table('company',...created_by('company'))
db.define_table('person_company', id_person('person'),
id_company('company'))
If you want to knwo what company ap person belongs to, look it up in the
link table
person = db.person.first()
link = db.person_company.id_person == person.id
company = db.company.id == link.id_company
This is the proper way to design this type of relationship.
I would opt more for a feature in web2py that did this in the background

Re: [web2py] Re: DAL() unusable ?
I still do not agree.
If you run into this issue you can always offset the created_by fields...
db.define_table('audit_table',
Field('tablename'), Field('record_id', 'integer'),
Field('created_by', db.auth_user),
)
If you ever did need to audit, just look it up in this table. Then you don't
have the problem at all.

My question is where is the database folder (it seems to be everywhere ;-)

Can it be set explicitly ?
It seems that the sql-log-file and the .table files are written in the CWD.
As a workaround I now keep track of the cwd,
and if I use define_table I first set the cwd to the database directory.
But I assume there are more actions where the cwd need to be set to the
database folder,
so I expect more problems/
I use the following to create the database:
Database_Name = r'D:\Data_Python_25\Beheer\ID_TO_Beheer_DAL.db'
My_DB = DAL ( 'sqlite://' + Database_Name )

Re: [web2py] standalone DAL: why is migration table name preceeded by some prefix ?
That is a hash of the connection string you pass in during DAL
instantiation. This way you can uniquely identify
db = DAL('sqlite://my.db')
vs
db = DAL('postgres://.')
without overwriting your .table files.

Re: [web2py] Stand Alone DAL and migrations (again)
Just my 2 cents.
Using the DAL on anything but web2py is going to be a pain in the ass and a
nightmare waiting to happen. This is due to its inherent forced procedural
coding style. You can wrap DAL calls as methods, but it just gets really
messy. I'm a clean code zealot, so I bet I care more than most.
For any kind of software your developing that uses object oriented
programming, use a database system that is structured around classes and
declarative bases. You will find this is much much much easier to integrate
into, for example a wxWidgets program, than the DAL is.

Re: [web2py] Re: Stand Alone DAL and migrations (again)
Its not about can it be used stand alone. Its about how you have to
structure your code when you do. The only reason the DAL works well with
web2py is because web2py is executed and designed to be functionally coded.
I would suggest SQLAlchemy. Its designed with OOP in mind, and offers more
features than the DAL. However, Like I said, if your not concerned with
using an OOP design, then the DAL Is probably fine.
I have been here, done this. I already have wrote wxWidgets applications
that attempted to use the DAL standalone. It worked... but I soon learned
SQLAlchemy was much better suited for the job. I speak from experience.
If all you are doing is one or two models, then DAL is probably is fine. My
application of using the DAL standalone contained over 50 models, all
interconnected and weaved into each other. I also needed to organize my code
and have all of the models split up into their own files.

There are a few tweaks to be made security wise for the demo, but I think its almost done. Register account.

There will also be featured plugins that the site admin can choose to display at the top of the index page. The admin can also download all demo applications and review them.

Re: [web2py] Re: Request for a logo - PluginCentral
It should be easy enough to add a service for a listing of plugins. Would come up with a design specification for the API you want? Your even welcome to make a checkout and just add an API to the plugincentral codebase if you get to it before I do. I don't see any reason why this would need to be two separate apps. I'm willing to give commit access to anyone who wants to help. At least for right now, I don't know of any plugins that have dependencies, and that part of the plugin spec still is not fleshed out. This is why I removed storing separate versions for each plugin and just have it store the latest version. I would love to have this work on GAE, but to be able to provide proper demonstration of plugins it requires being able to install an app into web2py. -- Thadeus On Mon, Oct 25, 2010 at 10:33 AM, mdipierro mdipie...@cs.depaul.edu wrote: yway, our projects may be compleme
Re: [web2py] Re: Error tickets by number of occurrence
I think this should be default for the ticket view.

Quite a while ago I wrote some code for my issue tracker to show

tickets by their number of occurrence.
The Idea behind this is that you will see the error that appears most
frequently and that needs fixing immediately. Since I am too busy to
finish the issue tracker I will just share the relevant code

[web2py] Request for a logo - PluginCentral
I am working on plugin central, finally have some free time to devote to the project. However I am a horrible artist, and wonder if anyone would like to help me with designing a logo? This is my color scheme White - body content #5E99E7 - Links main color (a light blue) #F5F4EF - Grey, page background I would like to use the new Ubuntu font since it is open source. -- Thadeus
