SQLite3 Module
|
||||
==============
|
||||
|
||||
Maintainer Contact
|
||||
------------------
|
||||
Andreas Piening (Nickname: apiening)
|
||||
<andreas (at) silverstripe (dot) com>
|
||||
|
||||
|
||||
Requirements
|
||||
------------
|
||||
SilverStripe 2.4 or newer
|
||||
|
||||
|
||||
Installation
|
||||
------------
|
||||
download, unzip and copy the sqlite3 folder to your project root so that it becomes a sibling of cms, sapphire and co.
|
||||
|
||||
either use the installer to automatically install SQLite or add this to your _config.php (right after "require_once("conf/ConfigureFromEnv.php");" if you are using _ss_environment.php)
|
||||
|
||||
$databaseConfig['type'] = 'SQLiteDatabase';
|
||||
|
||||
you are done!
|
||||
|
||||
make sure the webserver has sufficient privileges to write to that folder and that it is protected from external access.
|
||||
|
||||
|
||||
URL parameter
|
||||
-------------
|
||||
If you're trying change a field constrain to NOT NULL on a field that contains NULLs it aborts the action because it might corrupt existing records. In order to perform the action anyway add the URL parameter 'avoidConflict' when running dev/build which temporarily adds a conflict clause to the field spec.
|
||||
E.g.: http://www.my-project.com/?avoidConflict=1
|
||||
|
||||
Tested stacks
|
||||
-------------
|
||||
OSX leopard, XAMPP with PHP 5.3.0, SQLite3.6.3
|
||||
OSX leopard, MAMP with PHP 5.2.6, SQLite3.3.7
|
||||
Ubuntu, PHP 5.2.4, SQLite3.4.2
|
||||
WinXP, XAMPP with PHP 5.3.0, SQLite3.6.16
|
||||
|
||||
|
||||
Open Issues
|
||||
-----------
|
||||
- SQLite3 is supposed to work with all may not work with certain modules as they are using custom SQL statements passed to the DB class directly ;(
|
||||
- there is no real fulltext search yet and the build-in search engine is not ordering by relevance, check out fts3

## Maintainer Contact
|
||||
|
||||
Andreas Piening (Nickname: apiening)
|
||||
<andreas (at) silverstripe (dot) com>
|
||||
|
||||
## Requirements
|
||||
|
||||
* Silverstripe 4.0 or newer
|
||||
|
||||
## Installation
|
||||
|
||||
* Install using composer with `composer require silverstripe/sqlite3 ^2`.
|
||||
|
||||
## Configuration
|
||||
|
||||
Either use the installer to automatically install SQLite or add this to your _config.php (right after
|
||||
"require_once("conf/ConfigureFromEnv.php");" if you are using _ss_environment.php)
|
||||
|
||||
$databaseConfig['type'] = 'SQLite3Database';
|
||||
$databaseConfig['path'] = "/path/to/my/database/file";
|
||||
|
||||
Make sure the webserver has sufficient privileges to write to that folder and that it is protected from
|
||||
external access.
|
||||
|
||||
### Sample mysite/_config.php
|
||||
|
||||
```php
|
||||
<?php
|
||||
global $project;
|
||||
$project = 'mysite';
|
||||
|
||||
global $database;
|
||||
$database = 'SS_mysite';
|
||||
|
||||
require_once("conf/ConfigureFromEnv.php");
|
||||
|
||||
global $databaseConfig;
|
||||
$databaseConfig = array(
|
||||
"type" => 'SQLite3Database',
|
||||
"server" => 'none',
|
||||
"username" => 'none',
|
||||
"password" => 'none',
|
||||
"database" => $database,
|
||||
"path" => "/path/to/my/database/file",
|
||||
);
|
||||
```
|
||||
|
||||
Again: make sure that the webserver has permission to read and write to the above path (/path/to/my/database/,
|
||||
'file' would be the name of the sqlite db file)
|
||||
|
||||
## URL parameter
|
||||
|
||||
If you're trying to change a field constrain to NOT NULL on a field that contains NULLs dev/build fails because
|
||||
it might corrupt existing records. In order to perform the action anyway add the URL parameter 'avoidConflict' when
|
||||
running dev/build which temporarily adds a conflict clause to the field spec.
|
||||
E.g.: http://www.my-project.com/?avoidConflict=1
|
||||
|
||||
## Open Issues
|
||||
|
||||
- SQLite3 is supposed to work with all may not work with certain modules as they are using custom SQL statements
|
||||
passed to the DB class directly ;(
