# wt.rowaccess module

## Synopsis

The `wt.rowaccess` module provides a `TemplateCode` sub-class which provides an automatic way of creating replacements from values in a dictionary.

## Usage

This class is very simple to use. Simply ensure that the attribute named by `rowaccess_attrib` contains a dictionary with the keys and values you wish to have available as attributes. This can, for example, be done in `main`.

The module works by defining a `__getattr__` method that consults the named dictionary, so the dictionary keys can be used as attributes of the instance.

Example:

`<!--wt:item-->
<a href="item.html?id=$$%ID$$">$$title$$</a>
<!--wt:/item-->`

`import jon.wt.rowaccess as rowaccess
class item(rowaccess.RowAccess):
def main(self, template):
website.dbc.execute("SELECT ID,title FROM items")
for self.row in dbc.fetchall():
self.process(template)`

(Please note this example assumes your database connector can provide results as dictionaries.)

## class: RowAccess(TemplateCode)

### Public Class Variables

#### `rowaccess_attrib`

This variable may be overridden by subclasses. It is a string naming the attribute which contains the dictionary to be consulted to find replacements. The default value is `"row"`.
