Hi!

I've a problem with environment the SYMFONY_ENV var. In my case I've called app_env instance of symfony_env. But when composer install --no-dev there is a error

TASK [Install Composer's dependencies] ***********
\n An error occurred when executing the \"'cache:clear --no-warmup'\" command: \n PHP Fatal error: Uncaught ReflectionException: Class Doctrine\Common\DataFixtures\AbstractFixture not found in /var/www/project/src/AppBundle/DataFixtures/ORM/LoadUserData.php:10

My playbook:


  vars_prompt:
    - name: app_env
      prompt: "Enter the environment (prod|dev)"
      default: prod
      private: no

  environment:
    SYMFONY_ENV: "{{ app_env|lower }}"

   pre_tasks:
    - name: Convert entered App environment to lowercase
      set_fact:
        app_env: "{{ app_env|lower }}"
      tags:
        - always


  - name: Install Composer's dependencies
  composer:
    working_dir: "{{ symfony_root_dir }}"
    no_dev: "{{ 'yes' if ('prod' == app_env) else 'no' }}" 
   //I have also tried   no_dev: "{{ 'True' if ('prod' == app_env) else 'False' }}" 
  tags:
    - deploy
  when: code_changed

My project use doctrine:fixtures:load. As the docs say, I register the bundle in:


if (in_array($this->getEnvironment(), ['dev', 'test'], true)) {
            //default bundles
            $bundles[] = new Doctrine\Bundle\FixturesBundle\DoctrineFixturesBundle(); 

            if ('dev' === $this->getEnvironment()) {
             //default bundles
            }
        }

Do you know any idea that it can be ...? 😞
thanks!

Hey Juan,

Hm, at the first sight, it's correct. Let's debug a bit more. Could you SSH to your server and run "composer install" manually? Do you have the same error? Also, you could try to always install dev deps with simply "no_dev: no". Does it fix the problem? Btw, could you try it manually locally? Are you sure you don't have the same problem and fixtures could be loaded successfully locally?

Cheers!

HeyVictor

En aws server with ssh:
When I try composer install (dev) is all ok.


[OK] All assets were successfully installed.

But when I try: composer install --no-dev

More info:
In my LoadUser.php

When I installed composer with --no-dev the namespaces next are wrong, because not exits Doctrine\Common\DataFixtures.

use Doctrine\Common\DataFixtures\AbstractFixture;
use Doctrine\Common\DataFixtures\OrderedFixtureInterface;

|

Victor SFCASTS JuanLuisGarciaBorrego 8 years ago

Yes, this sounds correct if you register DoctrineFixturesBundle in AppKernel only for dev/test environments.

Cheers!

JuanLuisGarciaBorrego Victor 8 years ago edited

victor First I want to thank you for all your help, I have solved the error

The installation and configuration were right, but in DoctrineFixtures classes I was using a OrderedFixtureInterface old, at the current version is different....


//https://symfony.com/doc/master/bundles/DoctrineFixturesBundle/index.html
public function getDependencies()
    {
        return array(
            UserFixtures::class,
        );
    }

I'm really grateful to you

I will edit the first comment to report that the error is to another different problem than this lesson . Or if you wish, I can delete it so as not to confuse.

Thanks!

Victor SFCASTS JuanLuisGarciaBorrego 8 years ago

Hey Juan,

Don't worry too much about your previous comments, we'll keep them ;)

Hm, it's a bit weird that fixtures broke your prod environment even when you do not use fixtures in prod at all. But I really glad you got it working!

Cheers!

|

Victor SFCASTS JuanLuisGarciaBorrego 8 years ago

Hey Juan,

Hm, are you sure you include DoctrineFixturesBundle namespace in AppKernel for dev/test environment only? And what about your local machine? Does it work locally when you execute "composer install --no-dev"?

UPD: I can suggest you to try to upgrade Composer dependencies with "composer update". It will pull latest versions and regenerate composer.lock. Then, try to execute "composer install --no-dev" again.

Cheers!

Victor SFCASTS JuanLuisGarciaBorrego 8 years ago

Also, let's see SYMFONY_ENV works well, try to follow a few steps:
- SSH to AWS server
- cd /to/project/dir
- try again to install deps without importing SYMFONY_ENV, just execute: "composer install --no-dev"
- On this step you should see the error you reported, right?
- Now let's export prod environment var by executing: "export SYMFONY_ENV=prod"
- And in the same terminal tab you exported SYMFONY_ENV, execute again: "composer install --no-dev"

Do you still have that error? Or, does it work now?

Cheers!

JuanLuisGarciaBorrego Victor 8 years ago edited

HI victor ,
In local:

SYMFONY_ENV:
In local I have defined SYMFONY_ENV=prod

#~/.zshrc
export SYMFONY_ENV="prod"


When I run in my terminal$ echo $SYMFONY_ENV return prod

- composer install --no-dev [local] ..... BUUM!!!!

Victor,
I'm trying and I think
It's all ok.

First I run ansible-playbook -i ......... with environment DEV, so it installs :
- create BD
- schema update
- fixtures load

That is good, the next, I run with environment PROD, I ansible is happy and skypped Load data fixtures and Warmup cache.

But, this I think not is the workflow correct.

|

Victor SFCASTS JuanLuisGarciaBorrego 8 years ago

Hey Juan,

I agree, that sounds not quite right workflow. In prod environment you really need to skip loading fixtures, but you still need to clear/warm up the cache, but this time with "--env=prod" option. Also, for production you won't just update schema with bin/console doctrine:schema:update, you need to run migrations instead to prevent loosing data.

Cheers!

On prod environment I got this error:

fatal: [192.168.50.8]: FAILED! => {"changed": false, "cmd": ["/var/www/project/bin/console", "hautelook_alice:doctrine:fixtures:load", "--no-interaction"], "delta": "0:00:00.080143", "end": "2018-05-10 10:27:36.079665", "msg": "non-zero return code", "rc": 1, "start": "2018-05-10 10:27:35.999522", "stderr": "\n \n [Symfony\\Component\\Console\\Exception\\CommandNotFoundException] \n There are no commands defined in the \"hautelook_alice:doctrine:fixtures\" namespace. \n Did you mean this? \n generate:doctrine

Thats because of dev dependencies in composer.json, I believe. With commented SYMFONY_ENV: "{{ symfony_env|lower }}" or dev as environment in prompt everything works fine.

NB: this error will be removed by conditional logic in a next chapter.

Victor SFCASTS toporovvv 8 years ago edited

Hey toporovvv ,

Yes, most probably so... but to be sure you can open config/bundles.php file (app/AppKernel.php) and make sure this fixtures bundle is loaded in dev/test env only (not in prod). Actually, it's a best practice to not load fixtures in production which makes sense because you can accidentally overwrite prod data.

Cheers!
