I am getting a syntax error when trying to load the database.

I have done the following:

Downloaded the code
Run Composer
Update the .env file for postgresl
Run the 3 symfony console command

The problem I get is when it tries to insert the data in to the 'user' table. I can't seem to find the file that has the user data or sql commands to insert the data.

Could you tell me what error did you get? To insert the data you need to load the fixtures (after providing the database). Run bin/console doctrine:fixtures:load - if you're on Docker run symfony console doctrine:fixtures:load

Cheers!

I am not using Docker but I have tried both 'bin/console' and 'symfony console' and get the same error about executing the 'INSERT INTO' commands.

Here is a screenshot of the output after running the command.

Ohh, I think it is a Postgres thing. Try surrounding the name of the table user in backticks ( ` ). You'll need to add this to the User entity class

#[ORM\Table(name: '`user`')]
class User {}

Or, if that does not work, try renaming the table to something else. The problem is that user is a reserved word

Cheers!

That worked. I had to change the comment a little since this course is using the 5.2.6 version of Symfony.

I do everything it says on the README.md but when i try to run symfony console doctrine:database:create

i get this error:
In AbstractMySQLDriver.php line 112: An exception occurred in driver: SQLSTATE[HY000] [1045] Access denied for user 'root'@'localhost' (using password: NO)<br />SQLSTATE[HY000] [1045] Access denied for user 'root'@'localhost' (using password: NO)<br />

The Mysql service is running. and when I connect to mysql in my terminal using mysql -u root -p i don't get any errors

Hey @The-cocktail-E

Did you update the database connection environment variable? DATABASE_URL you can do so by creating a .env.local file

Cheers!

ARM architecture is not working fine with mysql 5.7 but this is the solution.

Run this command on terminal
docker pull --platform linux/x86_64 mysql<br />

Update the docker-compose.yaml file like that :

version: '3.7'
services:
    database:
        image: 'mysql:5.7'
        platform: linux/amd64

        environment:
            MYSQL_ROOT_PASSWORD: password
        ports:
            # To allow the host machine to access the ports below, modify the lines below.
            # For example, to allow the host to connect to port 3306 on the container, you would change
            # "3306" to "3306:3306". Where the first port is exposed to the host and the second is the container port.
            # See https://docs.docker.com/compose/compose-file/#ports for more information.
            - '3306'

Now run

docker-compose up -d

and

symfony console doctrine:database:create
symfony console doctrine:schema:update --force
symfony console doctrine:fixtures:load
