当我坚持对象邀请时，我有这个错误..我在邀请和候选人之间制作实体邀请内容映射...邀请中的ManyToOne和候选人中的OneToMany但是我有这个错误：
类型＆＃34; AppBundle \ Entity \ Candidate＆＃34;的预期值for association field＆＃34; AppBundle \ Entity \ Invitation＃$ candidate＆＃34;，got＆＃34; Doctrine \ Common \ Collections \ ArrayCollection＆＃34;代替。

代码表格类型：

代码控制器：
public function newAction($id,Request $request) {
try
{
$offer = $this->getDoctrine()->getRepository(OfferSkill::class)->findOneBy(['id'=>$id]);
$invitation = $this->getHandler()->invitation($offer, $request->request->all(), $request->isMethod(Request::METHOD_POST));
if ($invitation instanceOf Invitation) {
$url = $this->generateUrl('homepage');
return new RedirectResponse($url);
}
}
catch(InvalidFormException $e) {
return [
'form' => $e->getForm()->createView(),
'edit' => false,
];
}
return ['form' => $invitation->createView()];
}
现在我选择了多个候选人，但我有这个错误
答案 0 :(得分：1)
您无法在# build data
from StringIO import StringIO
import pandas as pd
df = pd.read_csv(StringIO("""Cliente,Fecha,Auth_domain,Sitio,Country,ECPM_medio
FF,15/12/2017,@ff,ff_Color,Afganistán,0.53
FF,15/01/2018,@ff,ff_Color,Afganistán,0.5
FF,15/01/2017,@ff,ff_Color,Alemania,0.34
FF,15/12/2017,@ff,ff_Color,Alemania,0.38
FF,15/01/2018,@ff,ff_Color,Alemania,0.37
""")).sort_values(by='Fecha')
# functions to parse
def compare_val(cur,past,future):
if cur <= past:
cur_adj = cur * .8
if cur_adj >= past:
return(past)
else:
return(cur_adj)
else:
if future >= past:
return(past)
else:
return(future)
def setval(v):
cur, past, future = v, v.shift(-1), v.shift(1)
v = [ compare_val(*x) for x in zip(cur,past,future)]
return(v)
# do the work
df['Recomendation_ECPM'] = df.\
groupby(['Cliente','Auth_domain','Sitio',"Country"])['ECPM_medio'].\
transform(setval)
df[ pd.notna(df['Recomendation_ECPM']) ]
中设置multiple => true，因为InvitationType和ManyToOne之间的关系为Candidate
因此，您需要删除Invitation选项或将关系更改为实体中的multiple
