Question

models.py

class KeySkills(models.Model):
    skills            = models.TextField()
    versions          = models.DecimalField(decimal_places=3,null=True,blank=True,max_digits=10,default=None)
    experience        = models.DecimalField(decimal_places=3,null=True,blank=True,max_digits=10,default=None)
    user              = models.ForeignKey(access_models.SeekerRegister,on_delete=models.CASCADE,related_name='key_skills',null=True,blank=True)

    def __str__(self):
        return "KeySkills"

查询：

KeySkills.objects.filter(skills__unaccent__icontains='python')
KeySkills.objects.filter(skills_text__search='python')

错误：

在这里，我正在尝试使用Django ORM查询进行搜索。并尝试使用以上两种查询方式，但是我遇到了以上错误。

请查看我的代码。

Answer 1

您需要在'django.contrib.postgres中添加INSTALLED_APPS' 另外，尝试此link

Answer 2

您需要在INSTALLED_APPS中添加“ django.contrib.postgres”：然后，您需要在数据库中安装扩展名“ unaccent”以执行此查询：

CREATE EXTENSION unaccent;

我是在pgadmin4内部执行查询的。

django错误，而无声搜索
