Question

我创建了Formtype UniversitaireType但是我有这个错误：

attribut condidat_id在我尝试命令php bin / console doctrine时没有在数据库中创建：schema：update --force（所有attributs在数据库中创建除了id_condidat）..我在实体Universitaire中映射OneToMany $ condidat < / p>

代码实体：

Answer 1

你的＆＃34; condidat＆＃34;你有两个错误。属性。

您使用了一对多（双向）。如果你想只有一个候选人＆＃34; Universitaire＆＃34; - 然后你必须使用一对一（双向）。

import os
import time
import hashlib


class SimpleFileCheckSum(object):

    def __init__(self, path):

        self.path = path
        self.output = {}

    def check_path_error(self):

        if os.path.exists(self.path) is True and os.path.isfile(self.path):
            return True
        else:
            return False

    def get_file_size(self):

        try:
            st_data = os.stat(self.path)
            get_size = str(st_data.st_size)

        except PermissionError:

            try:

                os_size_data = str(os.path.getsize(self.path))
                self.output["SIZE"] = os_size_data

            except:
                self.output["SIZE"] = "Error"

        else:
            self.output["SIZE"] = get_size

    def get_file_times(self):

        def convert_time_to_human_readable(get_time):

            return time.strftime("%Y-%m-%d %H:%M:%S", time.localtime(get_time))

        try:

            my_st_object = os.stat(self.path)

            file_creation_time = convert_time_to_human_readable(my_st_object.st_ctime)
            file_last_modified_time = convert_time_to_human_readable(my_st_object.st_mtime)

        except:
            self.output['TIMES'] = {"CREATION": "Error", "MODIFIED": "Error"}

        else:
            self.output['TIMES'] = {"CREATION": file_creation_time, "MODIFIED": file_last_modified_time}

    def get_file_full_path(self):

        try:

            get_full_path = os.path._getfullpathname(self.path)
            get_final_path = os.path._getfinalpathname(self.path)

        except:
            self.output['PATH'] = {"FULL": "Error", "FINAL": "Error"}

        else:
            self.output['PATH'] = {"FULL": get_full_path, "FINAL": get_final_path}

    def get_file_hashes(self):

        try:

            hash_md5 = hashlib.md5()
            hash_sha1 = hashlib.sha1()
            hash_sha256 = hashlib.sha256()
            hash_sha512 = hashlib.sha512()

            with open(self.path, "rb") as f:
                for chunk in iter(lambda: f.read(2 ** 20), b""):
                    hash_md5.update(chunk)
                    hash_sha1.update(chunk)
                    hash_sha256.update(chunk)
                    hash_sha512.update(chunk)

        except:
            self.output["HASH"] = {"MD5": "Error", "SHA1": "Error", "SHA256": "Error", "SHA512": "Error"}

        else:
            self.output["HASH"] = {"MD5": hash_md5.hexdigest(), "SHA1": hash_sha1.hexdigest(),
                                   "SHA256": hash_sha256.hexdigest(), "SHA512": hash_sha512.hexdigest()}

    def call_all(self):

        if self.check_path_error() is True:

            self.get_file_full_path()
            self.get_file_size()
            self.get_file_times()
            self.get_file_hashes()

            return self.output

        else:
            return {"Error": "Your Path is Not Valid"}


if __name__ == '__main__':

    file_info = SimpleFileCheckSum("Your_file_address")
    get_last_data = file_info.call_all()

    print("Your Raw Dict Output : ", get_last_data, "\n\n")

如果没有，而且一对多就是你想拥有的，那么你必须在class Universitaire { ## ... /** * Bidirectional One-To-One (Owning Side) * * @ORM\OneToOne( * targetEntity="AppBundle\Entity\Condidat", * inversedBy="universitaire", * cascade={"persist", "remove"} * ) * @ORM\JoinColumn( * name="condiat_id", * referencedColumnName="id" * ) */ private $condidat; class Condidat { ## ... /** * Bidirectional One-To-One (Inversed Side) * * @ORM\OneToOne( * targetEntity="AppBundle\Entity\Universitaire", * mappedBy="condidat", * ) */ private $universitaire;中设置＆＃34; condidat＆＃34;是一个数组集合
```
__construct()
```
如果我是你，我宁愿使用＆＃34;候选人＆＃34;用＆＃34; s＆＃34; - 显示，这是一个arrayCollection。
正如我已经说过的那样 - 你的例子是双向一对多。在这种情况下，我们使用mappedBy和inversedBy。您在其中设置加入列的实体是拥有方。当然，JoinColumn必须在＆＃34; Candidate＆＃34;实体。所以：
```
public function __construct()
{
    $this->condidat = new \Doctrine\Common\Collections\ArrayCollection();
}
```

我添加了class Universitaire { ## ... /** * Bidirectional One-To-Many (Owning Side) * Predicate: One Universitaire can have a lot of candidates * * @ORM\OneToMany( * targetEntity="AppBundle\Entity\Condidat", * mappedBy="universitaire", * cascade={"persist", "remove"} * ) */ private $condidats; class Condidat { ## ... /** * Bidirectional Many-To-One (Owning Side) * Predicate: Each Condidat belongs to one Universitaire * * @ORM\ManyToOne( * targetEntity="AppBundle\Entity\Universitaire", * inversedBy="condidats", * ) * @ORM\JoinColumn( * name="universitaire_id", * referencedColumnName="id", * onDelete="SET NULL" * ) */ private $universitaire;。如果你删除了universitaire，那么在每个＆＃34; condidate＆＃34;的字段统计中。你会看到空值。
