Question

我是使用Symfony的新手，今天我遇到了一个问题，我无法更改实体的属性：Doctrine不想将所做的更改插入到我的数据库中...

我寻找诸如here之类的答案，但没有找到解决方法。

当我是新手时，我在一个空白项目中再次尝试：

我创建一个新实体：

luc@Lucs-MacBook-Pro:~/SymfonyTest|master⚡ 
⇒  symfony console make:entity             

 Class name of the entity to create or update (e.g. TinyChef):
 > Product

 created: src/Entity/Product.php
 created: src/Repository/ProductRepository.php

 Entity generated! Now let's add some fields!
 You can always add more fields later manually or by re-running this command.

 New property name (press <return> to stop adding fields):
 > name

 Field type (enter ? to see all types) [string]:
 > 

 Field length [255]:
 > 

 Can this field be null in the database (nullable) (yes/no) [no]:
 > 

 updated: src/Entity/Product.php

 Add another property? Enter the property name (or press <return> to stop adding fields):
 > 



  Success! 


 Next: When you're ready, create a migration with make:migration

然后我进行迁移：

luc@Lucs-MacBook-Pro:~/SymfonyTest|master⚡ 
⇒  symfony console make:migration


  Success! 


 Next: Review the new migration "src/Migrations/Version20191122111110.php"
 Then: Run the migration with php bin/console doctrine:migrations:migrate
 See https://symfony.com/doc/current/bundles/DoctrineMigrationsBundle/index.html

我运行它：

luc@Lucs-MacBook-Pro:~/SymfonyTest|master⚡ 
⇒  symfony console doctrine:migration:migrate 

                    Application Migrations                    


WARNING! You are about to execute a database migration that could result in schema changes and data loss. Are you sure you wish to continue? (y/n)y

  ++ migrating 20191122111110

     -> CREATE TABLE product (id INT AUTO_INCREMENT NOT NULL, name VARCHAR(255) NOT NULL, PRIMARY KEY(id)) DEFAULT CHARACTER SET utf8mb4 COLLATE `utf8mb4_unicode_ci` ENGINE = InnoDB

  ++ migrated (took 36.5ms, used 16M memory)

  ------------------------

  ++ finished in 39ms
  ++ used 16M memory
  ++ 1 migrations executed
  ++ 1 sql queries

然后我向实体添加了一个新属性：

luc@Lucs-MacBook-Pro:~/SymfonyTest|master⚡ 
⇒  symfony console make:entity                

 Class name of the entity to create or update (e.g. FierceGnome):
 > Product

 Your entity already exists! So let's add some new fields!

 New property name (press <return> to stop adding fields):
 > description

 Field type (enter ? to see all types) [string]:
 > 

 Field length [255]:
 > 

 Can this field be null in the database (nullable) (yes/no) [no]:
 > 

 updated: src/Entity/Product.php

 Add another property? Enter the property name (or press <return> to stop adding fields):
 > 



  Success! 


 Next: When you're ready, create a migration with make:migration

当我尝试创建迁移时，它不起作用：

luc@Lucs-MacBook-Pro:~/SymfonyTest|master⚡ 
⇒  symfony console make:migration             


 [WARNING] No database changes were detected.                                                                           


 The database schema and the application mapping information are already in sync.

有人可以帮助我吗？如果我不了解它是如何工作的或其他什么...

谢谢！

我有同样的问题。清除缓存对我有用。

symfony console cache:clear

更改后实体未更新
