Magento REST API – Specified request cannot be processed and Class does not exist

Class \Vendor\ModuleName\Api\TestInterface does not exist

During development move things from local-src + symlink to app/code/{vendor}/{modulename} so that namespace and folder structure could match.

If you are using interfaces in your module then this is also true that you need to use full path reference in PHPdoc instead of use import and reference.

Both worked for me

Specified request cannot be processed

rest/V1/test/ – V in version needs to be capital letter (also in webapi.xml).

And just useful tip that you can extract interface out of existing class.

Create a Magento plugin

Name plugin classes after what they do rather than after their target class.

First create plugin class and then configure it in di.xml. Plugin “name” in di.xml is module name that it is located at.

Plugin classes are located in Plugin folder within respective module.

After plugins execute after the target method. As a second argument after methods take return value of the target method.

Create an empty Magento 2 module to vendor

Add repository section to Magento composer.json file with the following command. Path refers to the location of your module’s repository (or just local folder).

composer config repositories.robert-empty path ./local-src/robert-empty/

Then create composer.json, registration.php and etc/module.xml for the module. Manually, just copy from another module and update the content.

Then tell composer to install our module by referring to the package name defined in composer.json “name” field. This creates symlink with module repository to vendor folder.

composer require robert/module-empty

Then enable module. this command adds the module to app/etc/config.php file. List of modules to load and their load order. In database moduls are registered to setup_module table.

php bin/magento module:enable Robert_Empty && php bin/magento setup:upgrade

You can skip the first part of the command because setup:upgrade automatically enables new modules.

registration.php – makes the module visible.

etc/module.xml – lists depencencies in sequence node that have to be loaded first.

How to install Magento on local nginx

Not a tutorial but notes for myself

Creating vitual host (tutorial), user rights in /var/www/ (rights to group, user to group) and here even better guidance.

Before Magento I usually set up default WordPress installation first to test if php works well, database is ok and nginx has started.

Useful command: sudo mv wordpress/* /var/www/html – how to move content of whole directory somewhere

Order of Magento installation

As it is in the documentation. But you can be sure something goes wrong.

  1. Composer create-project to get the metapackage: composer create-project --repository-url=https://repo.magento.com/ magento/project-community-edition magento/
  2. Permissions, also sudo chown -R rbrt:www-data .  It is occasionally needed later too.
  3. php bin/magento install... (this is very long command you can find here)*
  4. If you need then you can also install sample data: php bin/magento sampledata:deploy (takes very long time) and you may also need to run php bin/magento catalog:images:resize to get the images shown in the store.

Clean Magento install with sample data is 1.4 GB, 109 thousand files (so creating and deleting may take long time), 410 database tables. For comparison, clean WordPress is just 12 tables.

*For this step you need ElasticSearch running. sudo systemctl start elasticsearchInstructions can be found here on Digital Ocean website.

Nginx conf

/etc/nginx/ -> nginx.conf

Restart: sudo systemctl reload nginx

Get ownership
sudo chown -R robert /var/www/html
Give ownership back to the webserver system user www-data.
sudo chown -R www-data:www-data /var/www/html

Conf

Create .conf to /etc/nginx/sites-available

Symlink conf to sites-enabled

sudo ln -s /etc/nginx/sites-available/abc.conf /etc/nginx/sites-enabled/

Symlinked conf updates itself automatically

Add custom domain to hosts file

sudo code /etc/hosts --user-data-dir

Rights

This did not work well…

First, you should ensure that your username is included in www-data group. If not, you can add your username as www-data group
sudo adduser $USER www-data
After that, you should change the ownership of /var/www to your username
sudo chown $USER:www-data -R /var/www

Set file permissions before Magento installation

https://devdocs.magento.com/guides/v2.4/install-gde/composer.html#set-file-permissions – but I am not shure what the before means.

Disable 2FA

php bin/magento module:disable Magento_TwoFactorAuth

Because otherwise you can not log into admin (because mail server does not work)

Post installation commands

php bin/magento setup:di:compile
php bin/magento indexer:reindex or php bin/magento indexer:status
php bin/magento setup:upgrade
php bin/magento setup:static-content:deploy -f
php bin/magento deploy:mode:set developer
php bin/magento cache:clean
php bin/magento cache:flush
php bin/magento module:disable Magento_Csp
php bin/magento module:disable Magento_TwoFactorAuth

Eestiblogid.eu – my hobby project

To improve my coding skills in a safe environment I should start working more on the hobby project eestiblogid.eu. I currently has ~150 weekly users so if I mess something up it should not be huge problem 🙂

Currently it is just 2 small services which I call Reader and Writer.

Reader is a small independent PHP application which basically reads the given list of XML files (RSS feeds) every hour and checks if there is anything new. If there is something new then entry is made to the database. Rules for detecting “new” are very primitive. Therefore, quite often you can see duplicate posts. Reader will probably stay as it is. I should just make the code cleaner from time to time, implement some logging etc.

Writer is also a small php application (using Twig for templating and Bootstrap for styling) to generate views for the front end and reading data from database.

There is no admin panel at the moment. I go straight to the database to edit things (remove, deactivate, delete etc).

Up next

What I would like to do now is to prepare REST endpoints for the front end. Probably it will be php backend built with Laravel or Lumen using their Eloquent ORM.

Front end should be built with React together with admin views for myself (using JWT for authentication).

I try to keep you informed of the progress under this eestiblogid.eu tag.

Update 09.03.22

It has been less than a month. I have not done anything (too busy with my internship). But, meanwhile, Lumen has become extinct (not being developed any further) and I am most probably considering GraphQL (with Lighthouse) insead of REST. So probably it is good that I have not done much.

Solution: Composer dependencies require a PHP version…

I tried to initiate new Laravel project and ran into an error. I have been using php 8.0.2 but Magento needed 7.4 so I switched to 7.4 and now I am having this issue with Composer 🙂

Your Composer dependencies require a PHP version “>= 8.0.2”. You are running 7.4.27.

PHP Fatal error: Composer detected issues in your platform: Your Composer dependencies require a PHP version “>= 8.0.2”. You are running 7.4.27. in C:\Users\john\AppData\Roaming\Composer\vendor\composer\platform_check.php on line 24

How to get the value of PHP_VERSION_ID

In terminal run php -a and then var_dump(PHP_VERSION_ID);  You should see the id. To exit you can use ctrl+c.

How to solve it

Open the platform_check.php file and update the PHP_VERSION_ID to what you currently have.

Not sure if it is the best practice but it works.

How to prepare for the TestDome php assessment – my mistakes and tips

3rd year IT student in search of an internship

5th semester at school is pretty much over by now. Only one small assignment to do on upcoming Tuesday Thursday. Hopefully, I will write about the semester at some point.

On Monday I am going to do PHP tests for the internship that I applied for. I am preparing for it at the moment by solving Testdome PHP exercises and PHP interview questions. If I succeed it would be a huge step for me to become a sufficient Magento developer one day.

PostgreSQL create db and user

I need it quite often during development (mainly school work) that I need to create new database together with new user that can only use this specific database. Here are three simple commands that do just that.

CREATE DATABASE robert_db;
CREATE USER robert WITH ENCRYPTED PASSWORD 'x1y2z3';
GRANT ALL PRIVILEGES ON DATABASE robert_db TO robert;

In development I usually keep db name and user name the same so that I have less variables to remember.
