Prestashop 1.7 admin module show template - module

Question

I have problem with my first module.
I create a module modules/fashion/fashion.php
<?php
class Fashion extends Module
{
function __construct()
{
$this->name = 'fashion';
$this->tab = 'administration';
$this->version = 1.0;
$this->bootstrap = true;
parent::__construct(); // The parent construct is required for translations
$this->page = basename(__FILE__, '.php');
$this->displayName = $this->l('Block Fashion');
$this->description = $this->l('Add a fashion block');
}
public function install()
{
if (!parent::install() ||
!$this->registerHook('header')) {
return false;
}
if (Shop::isFeatureActive()) {
Shop::setContext(Shop::CONTEXT_ALL);
}
$tab = new Tab();
$tab->active = 1;
$tab->class_name = 'AdminFashionController';
$tab->name = array();
foreach (Language::getLanguages(true) as $lang) {
$tab->name[$lang['id_lang']] = "Fashion";
}
$tab->id_parent = (int)Tab::getIdFromClassName('Fashion');
$tab->module = $this->name;
return $tab->add();
}
public function uninstall()
{
// Uninstall Tabs
$tab = new Tab((int)Tab::getIdFromClassName('Fashion'));
$tab->delete();
// Uninstall Module
if (!parent::uninstall())
return false;
}
/**
* Returns module content
*
* #param array $params Parameters
* #return string Content
*/
}
?>
What is more i create modules/fashion/controller/admin/FashionAdminController.php
<?php
class FashionAdminController extends ModuleAdminController
{
public function initContent(){
parent::initContent();
$this->setTemplate('fashion.tpl');
}
}
?>
And modules/fashion/views/templates/admin/fashion.tpl
<!-- Block mymodule -->
<div id="mymodule_block_left" class="block">
<h4>Welcome!</h4>
<div class="block_content">
<p>Hello,
{if isset($my_module_name) && $my_module_name}
{$my_module_name}
{else}
World
{/if}
!
</p>
<ul>
<li>Click me!</li>
</ul>
</div>
</div>
<!-- /Block mymodule -->
So, when i click in my Admin Panel the link Fashion the shows "The page is no found" Why? What i did wrong? Can someone help me?

Answer 1

At first, check if the menu(tab) has been created in the backend or not.
I also think that the admin controller name should start with ADMIN : AdminFashionController and use this name for tab class :
$tab->class_name = 'AdminFashion';
Sample from default module:
public function installTab()
{
$tab = new Tab();
$tab->active = 1;
$tab->class_name = "AdminLinkWidget";
$tab->name = array();
foreach (Language::getLanguages(true) as $lang) {
$tab->name[$lang['id_lang']] = "Link Widget";
}
$tab->id_parent = (int)Tab::getIdFromClassName('AdminParentThemes');
$tab->module = $this->name;
return $tab->add();
}
You have to add "active" and remove "position"(is automatic)
