本文介绍了使用Symfony2/Symfony3中的FOSUserBundle删除/替换电子邮件中的用户名字段的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我只想使用电子邮件作为登录方式，我不想拥有用户名. symfony2/symfony3和FOSUserbundle是否可能?

I only want to have email as mode of login, I don't want to have username. Is it possible with symfony2/symfony3 and FOSUserbundle?

我在这里阅读 http://groups.google.com/group/symfony2 /browse_thread/thread/92ac92eb18b423fe

但是后来我遇到了两个违反约束的问题.

But then I am stuck with two constraint violations.

问题是，如果用户将电子邮件地址留空，我得到两个约束违规:

Problem is if the user leaves the email address blank, I get two constraintviolations:

请输入用户名
请输入电子邮件

有没有一种方法可以禁用给定字段的验证，或者有更好的方法从表单中完全删除一个字段?

Is there a way to disable validation for a given field, or a better way toremove a field from the form altogether?

需要做的事情的完整概述

这里是需要完成的操作的完整概述.我列出了在本文末尾随处可见的不同来源.

A complete overview of what needs to be done

Here is a complete overview of what needs to be done. I have listed the different sources found here and there at the end of this post.

public function setEmail($email)
{
    $email = is_null($email) ? '' : $email;
    parent::setEmail($email);
    $this->setUsername($email);

    return $this;
}

2.从您的表单类型中删除用户名字段

(同时在RegistrationFormType和ProfileFormType中)

public function buildForm(FormBuilder $builder, array $options)
{
    parent::buildForm($builder, $options);
    $builder->remove('username');  // we use email as the username
    //..
}

3.验证约束

如@nurikabe所示，我们必须摆脱FOSUserBundle提供的验证约束，并创建我们自己的验证约束.这意味着我们将不得不重新创建先前在FOSUserBundle中创建的所有约束，并删除与username字段有关的约束.我们将创建的新验证组是AcmeRegistration和AcmeProfile.因此，我们将完全覆盖FOSUserBundle提供的内容.

3. Validation constraints

As shown by @nurikabe, we have to get rid of the validation constraints provided by FOSUserBundle and create our own. This means that we will have to recreate all the constraints that were previously created in FOSUserBundle and remove the ones that concern the username field. The new validation groups that we will be creating are AcmeRegistration and AcmeProfile. We are therefore completely overriding the ones provided by the FOSUserBundle.

fos_user:
    db_driver: orm
    firewall_name: main
    user_class: Acme\UserBundle\Entity\User
    registration:
        form:
            type: acme_user_registration
            validation_groups: [AcmeRegistration]
    profile:
        form:
            type: acme_user_profile
            validation_groups: [AcmeProfile]

3.b.创建验证文件`Acme\UserBundle\Resources\config\validation.yml`

那很长:

3.b. Create Validation file `Acme\UserBundle\Resources\config\validation.yml`

That's the long bit:

Acme\UserBundle\Entity\User:
    properties:
    # Your custom fields in your user entity, here is an example with FirstName
        firstName:
            - NotBlank:
                message: acme_user.first_name.blank
                groups: [ "AcmeProfile" ]
            - Length:
                min: 2
                minMessage: acme_user.first_name.short
                max: 255
                maxMessage: acme_user.first_name.long
                groups: [ "AcmeProfile" ]



# Note: We still want to validate the email
# See FOSUserBundle/Resources/config/validation/orm.xml to understand
# the UniqueEntity constraint that was originally applied to both
# username and email fields
#
# As you can see, we are only applying the UniqueEntity constraint to 
# the email field and not the username field.
FOS\UserBundle\Model\User:
    constraints:
        - Symfony\Bridge\Doctrine\Validator\Constraints\UniqueEntity:

        plainPassword:

                minMessage: fos_user.password.short
                groups: [ "AcmeRegistration", "AcmeProfile", "ResetPassword", "ChangePassword"]


FOS\UserBundle\Propel\Group:
    properties:
        name:
            - NotBlank:

                maxMessage: fos_user.group.long
                groups: [ "AcmeRegistration" ]

就是这样！你应该很好走！
