django column of relation does not exist の解決方法

Question

こんにちは。
Djangoを用いて作品投稿サイトを制作しているのですが、以下のエラーがどうしても取れません。
解消方法を教えていただきたいです。
よろしくお願いいたします。

使用しているデータベースはPostgreSQLです。

エラー：
column "title" of relation "cms_work" does not exist
LINE 1: INSERT INTO "cms_work" ("title", "contents", "create_user_id...

class WorkPost(CreateView):
    model = Work
    form_class = WorkPostForm
    template_name = "cms/workpost.html"
    success_url = "/"

#作品投稿フォーム
class WorkPostForm(forms.ModelForm):
    class Meta:
        model = Work
        fields = ('title', 'contents', 'create_user', 'create_date')
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        for field in self.fields.values():
            field.widget.attrs['class'] = 'input'

class Work(models.Model):

    title = models.CharField('タイトル', max_length = 255)
    contents = models.CharField('欲しいもの', max_length = 255, blank = True)
    create_user = models.ForeignKey(User, on_delete=models.CASCADE)
    create_date = models.DateTimeField(default=timezone.now)
    fav = models.IntegerField('いいね数')

##htmlです。
{% extends "cms/base.html" %}

{%block title %}workpost | {% endblock %}

{% block content %}
