Python Django筛选来自多个表的不同字段

我想从多个表中筛选不同的字段。例如，用户输入是“python，web开发人员”。我想同时显示“python”关键字技能匹配的作业和“web开发人员”标题匹配的作业

In User table

id  |  username  |  password
-----------------------------
1   |  employer1 |  sffddgfd
2   |  employer2 |  dfggfgfd

In Company Table

id  |  emp_id  |  companyname
-----------------------------
1   |    1     |  abc
2   |    2     |  xyz



In jobs table

+----+--------+--------------------+
| id | emp_id | title              |
+----+--------+--------------------+
|  1 |      1 | Software Developer |
|  2 |      1 | Software Developer |
|  3 |      1 | testing            |
|  4 |      1 | webdeveloper       |
|  5 |      2 | Software Developer |
|  6 |      2 | testing            |
|  7 |      2 | software           |

使用上面的命令，我得到了重复的结果，起初我只使用keyskill进行过滤。但同样的工作重复两次。我要筛选双硅酸盐字段。

您可以先拆分输入字符串：

key_skill, title = "python,web developer".split(',')

然后跨模型筛选作业：

jobs = Job.objects.filter(title=title, employerkeyskills__keyskills=key_skill)

您可以这样做：

jobs.object.filter(employerkeyskills_set__keyskills__in = ["python", "web developer"])

如果添加了相关的_名称arg：

class employerkeyskills(models.Model):
    emp=models.ForeignKey(User,unique=False)
    job=models.ForeignKey(jobs,unique=False, related_name='skills')
    keyskills=models.CharField(max_length=50)

jobs.object.filter(skills__keyskills__in = ["python", "web developer"])

您可以尝试：

details = employerkeyskills.objects.filter(keyskills__icontains=search).distinct()

class employerkeyskills(models.Model):
    emp=models.ForeignKey(User,unique=False)
    job=models.ForeignKey(jobs,unique=False, related_name='skills')
    keyskills=models.CharField(max_length=50)

jobs.object.filter(skills__keyskills__in = ["python", "web developer"])

details = employerkeyskills.objects.filter(keyskills__icontains=search).distinct()
