[web2py] Re: gevent and web2py
I think you can, but how is this related to web2py? I mean, you can even run gevent inside a function in a controller if you want. Like in the example, if you have an action that needs to check if three URLs are available, it will return faster if you query those URLs asynchronously (using gevent, or asyncio, or Twisted, etc.) El jueves, 1 de marzo de 2018, 13:04:35 (UTC-3), Pierre escribió: > > Hi, > > Can I use* gevent* to build a homemade redis task queue and to execute > these tasks?

[web2py] How many concurrent requests can a web2py instance handle?
I know this is probably not a specific web2py issue, but rather a WSGI one. I am somewhat confused. However, this is not the largely discussed "Does web2py scale?" question. I am wondering if a single web2py instance can handle two or more requests concurrently, or if two users access to the site at the same time, then one request is queued up? I am deploying a site in PythonAnywhere for a small business, with 4 web workers. I guess that means 4 web2py processes and that the webserver will dispatch incoming requests to one idle process of those four?

Thanks. I've already cloned. But remained confused how to update correctly. Normally I would just "git pull" but am not sure if I need to do something else to make sure DAL updated, too. -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups "web2py-users" group.

Re: [web2py] Re: Unexpected behaviour executing a query with DAL and record versioning enabled
Hmmm... I think that if you have record versioning activated there
shouldn't be any is_active row(s) with NULL value... I mean is_active flag
is used to determine if the record in the "parent" table has been deleted
or not, since you can truely deleted in case you use record versioning
feature as all the previous record stated records contained in the
versioning table reference the parent record in the parent table...
And you see in the second example here :
http://web2py.com/books/default/chapter/29/06/the-database-abstraction-layer?search=record+versioning#Record-versioning
That is_active is set to default=True and there is this note :
Notice the hidden boolean field called is_active and defaulting to True.
So if you have activated record versioning feature over an already existing
table you need to set is_active to TRUE for all the existing record once
you start using the versioning feature and set the is_active to be
mandatory...
I guess it would make sens to change seconde book example in orther that is
should be more obvious that is_active is mandatory like so :
db.define_table('stored_item',
Field('name'),
Field('quantity', 'integer'),
Field('is_active', 'boolean',
writable=False, readable=False, default=True,
required=True, requires=IS_NOT_EMPTY()))
That way you don't need to care about null value to get all the records of
the parent table and DAL is not bugged...

[web2py] Re: Unexpected behaviour executing a query with DAL and record versioning enabled
So, I did check it again:
It seems that DAL is not able to handle a left join using ISNULL condition
in combination with enabled record versioning.
There are two "is active" checks within the left join: OK
The next two upcoming ANDs to check "is_active" are not necessary and
actually prohibit the query to work properly.
To make this work it should be: AND (("test1"."is_active" = 'T') AND
(("test2"."is_active" = 'T' OR ("test2"."is_active" ISNULL ))
The two AND is active checks at the end of the query are not necessary at
all (my opinion).
Could somebody please verifiy this!

[web2py] Back button with an Ajax LOAD page
Hello.
I've made a product page with the Ajax LOAD system:
http://www.mompala.it/prodotti
The idea is giving the possibility to the user to browse these products
without a page reload, and it works fine.
The problem is that browsing the products don't change the url.
I've made a script that changes the content depending of the url.
If the url has a category_id like
http://www.mompala.it/prodotti?category_id=8 the load page will display the
products of this category.
If the url has a product_id like
http://www.mompala.it/prodotti?product_id=325 the load page will display
this product.
The problem still the history.
The user must have the possibility to press the browser back button for
displaying the last content.
Adding this script in the load page change the url in the browser url bar,
new_link is a link with the category_id or product_id:
history.pushState("", "", "{{=new_link}}");
Like that the back button change only the url bar content, not the page
content.
For updating the page content I've added in the main page 'prodotti' this
script:
window.addEventListener('popstate', function(event) {
location.reload();
});
And it works, but only for turning back to the last page.
In other words, if the user wanted to turn back in the history 2 pages in
the past he can't.
Someones knows why?
Thanks!
