Django从多个表中筛选不同的字段

我想从多个表中筛选不同的字段。例如用户输入是“python，web developer”。我想同时显示“python”keyskills匹配的作业和“web开发者”标题匹配的作业。Django从多个表中筛选不同的字段

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   | 
+----+--------+--------------------+ 

In employerkeyskills table 

+----+--------+--------+--------------------+ 
| id | emp_id | job_id | keyskills   | 
+----+--------+--------+--------------------+ 
| 1 |  1 |  2 | python    | 
| 2 |  1 |  2 | django    | 
| 3 |  1 |  2 | html    | 
| 4 |  1 |  3 | manual testing  | 
| 5 |  1 |  3 | automation testing | 
| 6 |  1 |  4 | css    | 
| 7 |  1 |  4 | javascript   | 
| 8 |  1 |  4 | html    | 
| 9 |  1 |  4 | php    | 
| 10 |  2 |  5 | python    | 
| 11 |  2 |  5 | php    | 
| 12 |  2 |  6 | SQL    | 
| 13 |  2 |  6 | Manual Testing  | 
| 14 |  2 |  7 | sql    | 
| 15 |  2 |  7 | testing   | 
| 16 |  2 |  7 | python    | 
| 17 |  2 |  7 | html    | 
+----+--------+--------+--------------------+

models.py

class User(models.Model): 
    username = models.CharField(max_length=100) 
    password = models.CharField(max_length=100) 

class company(models.Models): 
    emp = models.ForeignKey(User, unique=False) 
    companyname = models.CharField(max_length=100) 

class jobs(models.Model): 
    emp = models.ForeignKey(User, unique=False) 
    title = models.CharField(max_length=100) 

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

views.py

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

使用上述命令我得到重复的结果，在第一予过滤，用仅keyskills。但同样的工作重复两次。我想过滤重复字段。

您可以拆分输入字符串第一：

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

然后筛选工作Cross车型：

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

你可以这样做：

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

如果添加related_name 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()
