我正在使用PyroCMS 2.2.5模块，这就是我在details.php文件中所做的事情：

模块，显然 安装和卸载了，但我注意到这里缺少的东西，这就是我正在运行的问题，如果我知道了流的工作原理那么
data_streams表上会出现一个新行，对吧？在我的情况下没有创建，为什么？我错过了什么？与卸载模块时相反，对吧？data_field_assignments对吗？就我而言，在我没有发生这种情况之前，为什么呢？我错过了什么吗？有人可以给我一些帮助或建议吗？

这是一个关于如何使用流创建模块的简单样板：
假设名为my_module
public function install()
{
//Create your stream
if ( ! $this->streams->streams->add_stream(lang('streams:name'), 'my_module', 'my_module', '', null))
{
//Something went wrong so uninstall
$this->uninstall();
return false;
}
//Now we have the streams so create the fields
$fields = array(
array(
'name' => lang('my_module:fields:name'),
'slug' => 'my_fields_slug',
'namespace' => 'my_module',
'type' => 'text',
'extra' => array('max_length' => 100),
'instructions' => lang('my_module:fields:instr:name'),
'assign' => 'my_module',
'title_column' => true,
'required' => true,
'unique' => true
),
....
....
);
// Add fields to the stream
$this->streams->fields->add_fields($fields);
return true;
}
public function uninstall()
{
//remove stream
$this->streams->utilities->remove_namespace('my_module');
//Drop table, strems do not do that
$this->dbforge->drop_table('my_module');
return true;
}

你有一些文档需要阅读。
不要创建流表。不要丢弃它使用Streams Utility来销毁命名空间：http://docs.pyrocms.com/2.2/manual/developers/tools/streams-api/utilities-driver#remove_namespace(namespace_slug)。这将拆除该命名空间中的字段和分配。正确拆除一切。
仅使用流驱动程序添加流：http://docs.pyrocms.com/2.2/manual/developers/tools/streams-api/streams-driver#add_stream。这将创建表并自动添加data_streams记录。但如果表存在，则返回false，因为它假定Stream已存在。
添加字段时，需要使用字段驱动程序将它们分配到流：http://docs.pyrocms.com/2.2/manual/developers/tools/streams-api/fields-driver#assign_field(namespace,stream_slug,field_slug,assign_data:array)。这将自动创建列并为字段运行赋值挂钩。
