Question

我在Django中使用我的模型文件获得了以下错误。

＆＃34;文件＆＃34; /home/mosmith/Projects/MasteringDjango/mysite/books/models.py"，第23行，书中 authors = models.ManyToManyField（作者） NameError：name＆＃39;作者＆＃39;未定义＆＃34;

我已经看到人们遇到的其他问题正在解决这个问题，但是由于没有在通话之前定义模型。

这是我的models.py文件：

from django.db import models


    class Arthor(models.Model):
        first_name = models.CharField(max_length=30)
        last_name = models.CharField(max_length=40)
        email = models.EmailField()

        def __str__(self):
            return self.first_name

    class Publisher(models.Model):
        name = models.CharField(max_length=30)
        address = models.CharField(max_length=50)
        city = models.CharField(max_length=60)
        state_province = models.CharField(max_length=30)
        country = models.CharField(max_length=50)
        website = models.URLField()

    class Book(models.Model):
        title = models.CharField(max_length=100)
        authors = models.ManyToManyField(Author)
        publisher = models.ForeignKey(Publisher)
        publication_date = models.DateField()

Answer 1

<input type="text" name="TextInput1" id="TextInput1" placeholder="place holder" value="" required>
<input type="url" name="urlInput1" id="urlInput1" value="" required>
<input type="number" name="numberInput1" id="numberInput1" value="" required>
<input type="submit" onClick="return validate()" />
<script>
    function validate(){
    var text1 = document.getElementById('TextInput1').value;
    var text2 = document.getElementById('urlInput1').value;
    var text3 = document.getElementById('numberInput1').value;
    var cnt = 0;

    if (text1.length > 0 || text2.length > 0 || text3.length > 0){
        alert("working");
        return true;
    }
    alert("please enter something");
    return false;
    }
</script>

更改为AUTHOR，而不是ARTHOR。
