I found in Symfony docs that you can Generate Entities from an Existing Database so are there any ways to update entities from existing database I added using MySQL?
For example, I added new column to my FOSUSERBUNDLE database called "batman"
using this command on MySQL:
ALTER TABLE cs_symfony_members
ADD batman int(11) NOT NULL;
how to update my entities i generated using the docs guide above ?
If you need to update database schema to Entity, you can use two command:
(1) Create entity mapping from database:
bin/console doctrine:mapping:import BundleName --filter=EntityName
(2) Update your entity to match this mapping:
bin/console doctrine:generate:entities BundleName:EntityName
Example, I have a User table in database, a had changed structure of this table. And now, I want to update these changes to my User entity in AppBundle. I need to run following command:
bin/console doctrine:mapping:import AppBundle --filter=User
bin/console doctrine:generate:entities AppBundle:User
I hope this can help you!
For anybody who is having trouble finding this command after forgetting, like me, here it is:
When i update my Entities from my already existing sql database, I juste use this command:
php bin/console doctrine:mapping:import --force AppBundle annotation --filter="Entity name".
I'm using symfony 3.4 but I'm gussing this also works for later versions.

Following: https://symfony.com/doc/current/doctrine/reverse_engineering.html
The command: php bin/console doctrine:mapping:import "App\Entity" annotation --path=src/Entity overwrites current Entity/* files, instead of just updating them with new columns from the database.
What is the standard method for updating entities pragmatically from the database without overwriting custom functions / logic in the existing Entity files?
php bin/console make:entity --regenerate
Seems to help in regenerating the entity from the db without overwrite.
I have an existing table with 5 columns, and I want to generate an Entity without that generates a new migration with new table!
Thanks!
So, as I mentioned in comment - you just need to follow steps in Symfony documentation.
This way, for Symfony 3 you need follow this:
php bin/console doctrine:mapping:import --force AppBundle xml
This command line tool asks Doctrine to introspect the database and generate the XML metadata files under the src/AppBundle/Resources/config/doctrine folder of your bundle.
Once the metadata files are generated, you can ask Doctrine to build related entity classes by executing the following command.
php bin/console doctrine:mapping:convert annotation ./src
It will generate Entity classes, and after that you must to remove the XML files, generated by first command.
Its symfony 2 - doctrine issue.
I was trying to add some more fields to one of my tables in MySQL. After modification, i had run the command doctrine mapping import and doctrine generate entities commands, but the Entity_name.php file under Bundle/Entity/ folder not getting updated. Can anyone help me ?
Thanks and regards,

Your message is brief, but my interpretation is that you are trying to ADD more fields to an existing table, by creating a NEW entity. This doesn't sound like the correct workflow. The entity ought to already exist, and to add fields to the table, will require adding new properties, correctly annotated, to the existing Entity.
What commands are you running, and what command line output are you seeing? The doctrine based SF2 commands offer reasonable information upon failure.
Try to run this command:
$ php app/console doctrine:schema:update --force
When we initially designed our project, we had a couple of entities that to date are unused (and we don't plan to implement them in the near future). Ergo I want to remove them from my project. I would proceed like this (all steps manually performed):
Remove all relations from my currently used entities.
Delete the doctrime ORM file src/Resources/config/doctrine
Delete the class PHP file from src/Entity
Remove the table from the database
What I would like to know: Are there any routines (e.g. console commands) that may support this procedure? For example, if I run
php app/console doctrine:schema:update --dump-sql
after having removed all relations and deleted the files, that I get the SQL statement that removes the according table(s)?
Once you have removed the entities from your code, you can use the following console command to drop the tables:
php bin/console doctrine:schema:update --complete --dump-sql
Note the use of the --complete option.
Here are the relevant parts from the doctrine:schema:update help text:
Options:
--complete If defined, all assets of the database which are not relevant to the current metadata will be dropped.
[...]
Help:
[...]
Finally, be aware that if the --complete option is passed, this task will drop all database assets (e.g. tables, etc) that are not described by the current metadata. In other words, without this option, this task leaves untouched any "extra" tables that exist in the database, but which aren't described by any metadata.
Hint: If you have a database with tables that should not be managed by the ORM, you can use a DBAL functionality to filter the tables and sequences down on a global level:
$config->setFilterSchemaAssetsExpression($regexp);
to remove the table in symfony 3 you can just run a migration and the table not in use will be dropped from the DB:
php bin/console doctrine:migrations:diff
php bin/console doctrine:migrations:migrate
Your steps to delete an entity are OK.
You can't remove a table from Doctrine, as Doctrine doesn't know about it. Have a look at this question:
Deleting table using Doctrine2 and Symfony2
I've created a new database with the SQL CREATE DATABASE command to host my application tables. I would now generate the database from my Symony 2.1 project using Doctrine. I already have the correct mapping YML-PHP entities but when I try to use the command
php app/vendors doctrine:schema:create
it fails on a query that I run inside my application. What I don't understand is why it seems that it's trying to boot my bundle and so obviously it fails because the queries that I execute don't find the tables. How can I generate the new database?
Base table or view not found: 1146 Table 'mydatabase.mytable_menu' doesn't exist
That command only creates the database for you. You will need to run this command to generate the actual database tables for your entities.
php app/console doctrine:schema:update --force
