我有JSON对象，用于作业具有按键调用技能并且是技能列表的JSON对象。例如使用django和mongoengine执行正则表达式查询
{
"_id" : ObjectId("552a42cd03462b0728feb180"),
"did" : "JB77FW6885MCCRGG30T",
"attributes" : {
"EducationRequired" : "Bachelor's Degree",
"ExperienceRequired" : "At least 3 year(s)",
"ExternalApplication" : "True",
"City" : "Houston",
"Company" : "IBM",
"DegreeRequired" : "4 Year Degree",
"Skills" : {
"Skill" : [
"apache hadoop",
"etl",
"geographic information system",
"cloud computing",
"mongodb",
"nosql",
"linux",
"spark (programming language)",
"java (programming language)",
"python (programming language)",
"sql",
"machine learning",
"data management",
"data integration"
]
}
}
}
{
"_id" : ObjectId("552a42cd03462b0728feb180"),
"did" : "JB77FW6885MCCRGG30T",
"attributes" : {
"EducationRequired" : "Bachelor's Degree",
"ExperienceRequired" : "At least 5 year(s)",
"ExternalApplication" : "True",
"City" : "Boston",
"Company" : "Microsoft",
"DegreeRequired" : "4 Year Degree",
"Skills" : {
"Skill" : [
"java (programming language)",
"python (programming language)",
"sql",
"machine learning",
"data management",
"data integration"
]
}
}
}
我想有“SQL”或'Java的
的工作，我有以下呼叫
skills = ['java','sql']
jobs = Job.objects(__raw__={'attributes.Skills.Skill' : {'$in' : skills}})
这样做的问题是，它不返回具有'java'的作业，因为在数据库中，技能列表具有'java（编程语言）'而不仅仅是'java'。为了解决这个问题，我需要在查询中添加一个正则表达式。所以我尝试了以下但他们都没有工作：
Job.objects(__raw__={'attributes.Skills.Skill' : {'$in' : ['$/.*java.*/']}}) #ignoring sql for now
Job.objects(__raw__={'attributes.Skills.Skill' : {'$in' : ['sql',re.compile('$/.*java.*/', re.IGNORECASE)]}})
Job.objects(__raw__={'attributes.Skills.Skill' : {'$in' : ['sql',re.compile('/.*java.*/', re.IGNORECASE)]}})
任何想法，我应该做什么？
为什么不直接看'java（编程语言）'？像'skills = ['java（编程语言）'，'sql']'？ – BorrajaX
，因为java平台等数据中还有其他java（xxxxxx）实例。通常候选人都有Java技能，但职业生涯API有java（编程语言）等等。 – Amer
