laravel - Can I create controller from a controller? - laravel

I've a controller to create a controller. SiteController is an example.
public function createSiteController() {
$controller_name = "SiteController";
Artisan::call("make:controller",
[
"name"=>$controller_name
]);
}
It gives me following error.
file_put_contents(/Volumes/Data/www/cms/app/Http/Controllers/SiteController.php):
failed to open stream: Permission denied
Tried to set chmod("/Volumes/Data/www/cms/app/Http/Controllers", 0777), but it is not permitted.
Edit: Of course, i don't want to use 0777. It was just an example. I would never use that. I am just saying

So, I had a problem to create a controller using a controller. I was unable to do it using artisian command.
Why I need that?
I've created an artisian command. something like this. (php artisian cms:controller controllerName)
It should be extended to BaseAdminController rather than default Controller. So I've made a template to create a custom controller. Just like laravel itself does.
I've fixed this problem using below steps.
* First you need to make a new file in a temp folder.
* Manipulate/Change whatever you want in that file.
* and copy that file (Controller in my case) to your Controller folder using copy command.

Laravel export downloadable CSV file

I am trying to write an endpoint which exports the data from the users table i currently have into a CSV file which is downloaded upon clicking of a button. I have setup the controller, routes, export file, and added in the button within the view but everytime i go to click the button it just directs me to the admin/user/export then gives me a 404 but shouldnt it just stay on the same URL then just add the file to my downloads file?
This is the package i am using for Laravel
https://github.com/maatwebsite/Laravel-Excel
web route
Route::get('users/export', 'Admin\UserController#export')->name('users.export');
UserExport
class UsersExport implements FromCollection
{
public function collection()
{
return User::all();
}
}
Controller Function
public function export()
{
return Excel::download(new UsersExport, 'users.csv');
}
Summarise problem:
Everytime i click the button on the view page it directs to admin/users/export then gives me a 404 when i want it to just download the CSV file for the users.
Some help to see where i am wrong would be helpful!
Thanks.
The problem is that two of your routes conflict with each other.
Given the following two routes:
Route::get('users/{user}', 'Admin\UserController#show')->name('users.show');
Route::get('users/export', 'Admin\UserController#export')->name('users.export');
Currently Laravel assumes that when you are trying to access users/export you actually want to access users/{user} with export as the route parameter {user}.
Making sure that users/export is registered before users/{user} should solve your issue:
Route::get('users/export', 'Admin\UserController#export')->name('users.export');
Route::get('users/{user}', 'Admin\UserController#show')->name('users.show');

Redirection issue in Codeigniter4

I have done admin controller and put that in a sub folder named 'Admin'
Controller
Admin
-login.php
Now I want to fetch that by router file where I wrote this
$routes->get('admin', 'Admin/Login::index');
But it is showing me "Not found" error and redirects to "http://localhost/admin".
Could there be some .htaccess issue?
replace this
$routes->get('admin', 'Admin/Login::index');
with
$routes->get('admin', 'Admin\Login::index');
also make sure you add namespace in your login.php
namespace App\Controllers\Admin;
If you keep CI4's directory structure intact you could in fact use sub-folders for Controllers, Models, Views, etc.
For example app/Controllers/Admin/Login.php is a valid place to put a Controller class. Make sure to add the appropriate namespace in Login.php - namespace App\Controllers\Admin; Also in routes - $routes->get('admin', 'App\Controllers\Admin\Login::index'); It is quite possible to work without the prefix of App\Controllers, but I never extensively tested it and I think there was a problem in some versions of CI4 before.
Another issue could be your app/Config/App.php class. If you did not change anything in your .htaccess file (the one in public directory!), $baseURL should be set to your public directory address - http://localhost/myproject/public/ . Or if you wish to make it easier - set up virtual hosts.
Just a thing to add - get() method in $routes allow only GET requests, meaning if you are trying to POST something (or use any other HTTP request method) it will fail and redirect.

OctoberCMS and BotMan

I want to integrate a chatbot (BotMan version 2.0) into an existing OctoberCMS project , here is what I did till now :
1- I added BotMan to the projct using the following command :
composer require botman/botman
2- I created a routes.php file in the same directory as the plugin.php file
<?php
use BotMan\BotMan\BotMan;
use BotMan\BotMan\BotManFactory;
use BotMan\BotMan\Drivers\DriverManager;
//Route::match(['get', 'post'], '/botman', 'BotManController#handle');
//Route::get('/botman/tinker', 'October\Demo\BotManController#tinker');
// Create an instance
$botman = BotManFactory::create($config);
// Give the bot something to listen for.
$botman->hears('hello', function (BotMan $bot) {
$bot->reply('Hello yourself.');
});
// Start listening
$botman->listen();
My questions are :
1- Where I have to add the BotManController.php file
2- I tried to add BotManController.php in the same directory as the routes.php file but I get the following error :
Class 'App\Http\Controllers\Controller' not found
( and thats because its an OctoberCMS project not Laravel project ... I dont have the App directory )
Can anyone please provide me a solution to that or another way to integrate Botman into OctoberCMS !
First off, read https://luketowers.ca/blog/how-to-use-laravel-packages-in-october-cms-plugins/ as well as https://octobercms.com/docs/plugin/composer.
Secondly, you can put the BotManController file anywhere in your plugin you want as long as you understand PHP namespaces and how to properly reference it where you want to. I would probably recommend putting it in a /classes/ directory under your plugin folder, and then changing the App\Http\Controllers\Controller reference to instead reference the base Illuminate\Routing\Controller class. You could also put it in a /controllers/ directory, but in OctoberCMS that is typically reserved for your backend controllers so I wouldn't recommend mixing the two.

Laravel Controller not working

I'm very new to the Laravel framework and am trying to load a simple controller in my browser to slowly get the hang of things.
I have a file that's titled users.php inside of the the laravel/app/controllers/ folder and it looks like this:
class UsersController extends BaseController
{
public $restful = true;
public function action_index()
{
echo 'hi';
}
}
In the routes.php file, I have
Route::get('users', 'UsersController#index');
But, when I go to
http://localhost:8888/laravel/public/users
I'm greeted with a message that says "ReflectionException
Class UsersController does not exist"
I'm not sure if this is because I didn't install the mcrypt extension of PHP. But, when I checked the php.ini file on MAMP, it said that it was enabled. Upon entering
which PHP
in my terminal, it said /usr/bin/php. So, it might not be using the correct version of PHP.
I'm not entirely sure if this is a routes problem or if it's stemming from an absence of a vital PHP extension.
Thanks a bunch!
You need to use the Route::controller method to reference your Controller:
Route::controller('test', 'TestController');
...and rename your file (as Cryode mentions ) to be TestController.php.
Note - if you want to use the filename as test.php, then you will need to use composer to update the autoload settings.
Finally, the format of names for Controller methods changed in Laravel 4, try renaming the method
public function action_index() {}
to be
public function getIndex() {}
the get represents a HTTP GET request... the same applies for post (HTTP POST) and any (GET or POST.. )
I'm not familiar with that part of Laravel's source, so I'm not entirely certain that this is the issue, but your controller file name should match the controller class name, including capitalization.
So users.php should be UsersController.php. Now, when I do this myself on purpose, I get a "No such file or directory" error on an include() call, so that's why I'm not certain that's the sole cause of your problem. But it may be a start.

Laravel 4 - changing resource root routing path

In a Laravel 4 installation, Using Jeffrey Way's Laravel 4 Generators, I set up a 'tweet' resource, using the scaffolding command from his example:
php artisan generate:scaffold tweet --fields="author:string, body:text"
This generated the model, view, controller, migration and routing information for the tweet type. After migrating the database, visiting http://localhost:8000/tweets works fine, and shows the expected content.
The contents of the routes.php file at this point is:
Route::resource('tweets', 'TweetsController');
Now I would like to move the url for tweets up one level into admin/tweets, so the above url should become: http://localhost:8000/admin/tweets. Please note that I am not treating 'Admin' as a resource, but instead just want to add it for hypothetical organizational purposes.
Changing the routes.php file to:
Route::resource('admin/tweets', 'TweetsController');
Does not work, and displays the following error:
Unable to generate a URL for the named route "tweets.create" as such route does not exist.
Similarly when using the following:
Route::group(array('prefix' => 'admin'), function() {
Route::resource('tweets', 'TweetsController');
});
As was suggested in this stackoverflow question.
Using php artisan routes reveals that the named routes also now have admin prefixed to them, turning tweets.create into admin.tweets.create.
Why is the error saying that it cannot find tweets.create? shouldn't that automatically be resolved (judging by the routes table), to use admin.tweets.create?
How can I change my routing so that this error no longer occurs?
I just tested with new resource controller and it works fine for me.
The problem is not with the Route, its with the named routes used in your application.
check your view files there are link to route like link_to_route('tweets.create', 'Add new tweet'), this is creating the error because when you add admin as prefix tweets.create doesn't exists so change it to admin.tweets.create every where, in your controller also where ever named route is used.
