无法确定类 "AppBundleEntity" 中的属性"skills"的访问类型

Question

我在 2 个条目中映射了多对多，但我有这个错误：

无法确定类"AppBundle\Entity\"中的属性"技能"的访问类型。

代码实体公司：

/**
           * @var SkillInterface[]
           *
           * @ORMManyToMany(targetEntity="Skill", inversedBy="companys", cascade={"all"})
           * @ORMJoinTable(name="companys_has_skills",
           *   joinColumns={
           *     @ORMJoinColumn(name="company_id", referencedColumnName="id")
           *   },
           *   inverseJoinColumns={
           *     @ORMJoinColumn(name="skill_id", referencedColumnName="id")
           *   }
           * )
           * @AssertCount(min = 1)
           */
          private $skills;
          public function __construct()
          {
              $this->skills = new ArrayCollection();
          }

           /**
           * Add skills.
           *
           * @param SkillInterface $skills
           *
           * @return Company
           */
          public function addSkills(AppBundleEntitySkill $skills)
          {
              $this->skills[] = $skills;
              return $this;
          }
          /**
           * Remove skills.
           *
           * @param SkillInterface $skills
           */
          public function removeSkills(AppBundleEntitySkill $skills)
          {
              $this->skills->removeElement($skills);
          }
          /**
           * Get skills.
           *
           * @return Collection
           */
          public function getSkills()
          {
              return $this->skills;
          }

代码实体技能：

/**
                * @var Collection
                *
                * @ORMManyToMany(targetEntity="Company", mappedBy="skills")
                */
               private $companys;
                /**
                * Constructor.
                */
               public function __construct()
               {
                   $this->companys = new ArrayCollection();
               }
               /**
                * Add company.
                *

                *
                * @return Skill
                */
               public function addCompany(AppBundleEntityCompany $company)
               {
                   $this->companys[] = $company;
                   return $this;
               }
               /**
                * Remove company.
                *
                * @param AppBundleEntityCompany $company
                */
               public function removeCompany(AppBundleEntityCompany $company)
               {
                   $this->companys->removeElement($company);
               }
               /**
                * Get companys.
                *
                * @return DoctrineCommonCollectionsCollection
                */
               public function getCompanys()
               {
                   return $this->companys;
               }

现在我在 2 个实体中制作了删除、添加和获取变量的功能，但我也有错误，我初始化为 arrayCollection

Answer 1

函数名称应该addSkill和removeSkill而不s。
