web2py is a Python library typically used in Database applications. web2py has no bugs, it has build file available and it has medium support. However web2py has 1 vulnerabilities and it has a Non-SPDX License. You can download it from GitHub.

An important part of web2py is the Database Abstraction Layer (DAL). In early 2015 this was decoupled into a separate code-base (PyDAL). In terms of git, it is a sub-module of the main repository. The use of a sub-module requires a one-time use of the --recursive flag for git clone if you are cloning web2py from scratch.

If you are using SQLite, you may have initially defined the field as type double (or decimal) and later "migrated" to type string. As noted here, such migrations have no effect in SQLite, so SQLite will continue to treat the column as numeric and coerce values to numbers when possible (SQLite does not complain about storing non-numeric strings in the column because it does not have rigid column types -- it simply has type affinities, which determine what types of coercions may happen -- see https://www.sqlite.org/datatype3.html).

You'll have to re-create the table, starting with the correct column type.

It seems like you are trying to access a client side element ('TablaMateriales') on the server side. You can only do that if you explicitly pass the element back to the server.

And then you would need to manipulate it using something like http://web2py.com/books/default/chapter/29/05/the-views#Server-side-DOM-and-parsing

You could just count the number of rows using JavaScript from inside the view: JavaScript to get rows count of a HTML table

To check whether it's a string: if isinstance(firstname, str)

To check whether non-empty: you can do if firstname != '' or if firstname; in Python, empty objects are treated as being "False" when used as a boolean. To check whether it's letter characters, you can do if firstname.isalpha().

Smells like a windows permission issue, according to official docs:

os.path.exists(path) Return True if path refers to an existing path or an open file descriptor. Returns False for broken symbolic links. On some platforms, this function may return False if permission is not granted to execute os.stat() on the requested file, even if the path physically exists.

so you should either give yourself permissions to access that folder (not recommended), or just copy the font to a directory you own.

Web2py Number Formatting for Thousands

Asked 2020-Jul-31 at 14:49

I'm sort of new to Web2py. I have a system that's working just fine, but I want to make an improvement regarding visualization. There's a couple of fields that use numbers (defined as double in their respective define_table methods) to represent currency, but I want them to also show with a separator for thousands, such as 183,403,293.34. I checked some documentation, but I couldn't find a direct way to handle this form of customization, though I could be missing something.

Any suggestions regarding this? Cheers!

ANSWER

Answered 2020-Jul-28 at 01:44

First, if representing currency, you should use the decimal field type rather than double (some calculations using double values may yield incorrect results due to the use of floating point representations internally). However, if using SQLite, there is no distinction between decimal and double, so in that case, you might want to multiply all values by 100 and instead store integers.

In any case, to display a given numeric value with thousands separators in Python, you can do:

QUESTION

What performance hit does using "rows.render()" have in web2py?

Asked 2020-Jul-15 at 20:43

I have found that using the 'Represents' functionality as described in http://web2py.com/books/default/chapter/29/06/the-database-abstraction-layer?search=lazy#Rendering-rows-using-represent slows things down quite a lot - more than doubles the time it takes to process some tables. This is a shame because this option makes it really easy to get human readable data from very simple table SELECTs.

I think this performance is to be expected since I assume it is issuing a SELECT for every record to get the Represents values. So I have 1 SELECT for my set of, say, 100 records and then there is another 100+ SELECTS to get the Represent values for the fields in one or more related tables as I access those records.

Any tips on how to improve the render() function performance? Or should I expect the render() option to be sluggish? Is the only alternative to build a query with the necessary joins in order to get the Represents data?

Thanks

ANSWER

Answered 2020-Jul-15 at 20:43

By default, reference fields that refer to a related table with a format attribute defined will get a represent function that does indeed select the related record (and then applies the format function/specification to the retrieved record), leading to the "N+1" query problem you have observed.

If you still want to make use of rows.render() to apply the represent functions of other types of fields that do not involve database selects, you can eliminate the problem for reference fields by explicitly removing their default represent attributes:

Web2py layout configuration settings

Asked 2020-Jun-24 at 11:56

The web2py online book in Chapter 3 Overview says that in the scaffolding application, values for response.title, response.meta.author, etc, are set in the file models/menu.py. While previous versions of Web2py did include the settings in menu.py, in v.2.18.5 the default values are not set in this file. While some of the settings, such as response.meta.author etc are defined in models/db.py, response.title and response.subtitle could not be found in db.py also. The online book does say that these can be defined in any model file. Can someone advise where these settings are now defined?

ANSWER

Answered 2020-Jun-24 at 11:56

It appears that those items are no longer defined in the scaffolding app. The default layout simply using request.application as the page title if request.title is not defined. Feel free to define those items wherever, or not at all.
