我正在关注django_rest_framework教程,我坚持了第4部分。 问题在于,每当我尝试通过消费发布新代码片段时 127.0.0.1:8000/snippets/ with curl或httpie一切正常。
但是每当我想通过使用django_rest_framework生成的可浏览API来实现它时
// Do definition and execution at the same time.
var someFunction = (function someFunction() {
// do stuff
return someFunction
})();
console.log(someFunction)
我总是得到:
code = models.TextField()
这怎么可能?
这是我的models.py
HTTP 400 Bad Request
Content-Type: application/json
Vary: Accept
Allow: GET, POST, HEAD, OPTIONS
{
"code": [
"This field is required."
]
}
这是我的serializers.py
from django.db import models
from pygments import highlight
from pygments.lexers import get_all_lexers, get_lexer_by_name
from pygments.styles import get_all_styles
from pygments.formatters.html import HtmlFormatter
LEXERS = [item for item in get_all_lexers() if item[1]]
LANGUAGE_CHOICES = sorted([(item[1][0], item[0]) for item in LEXERS])
STYLE_CHOICES = sorted((item, item) for item in get_all_styles())
class Snippet(models.Model):
created = models.DateTimeField(auto_now_add=True)
title = models.CharField(max_length=100, blank=True, default='')
code = models.TextField()
linenos = models.BooleanField(default=False)
language = models.CharField(choices=LANGUAGE_CHOICES, default='python', max_length=100)
style = models.CharField(choices=STYLE_CHOICES, default='friendly', max_length=100)
owner = models.ForeignKey('auth.User', related_name='snippets')
highlighted = models.TextField()
def save(self, *args, **kwargs):
"""
Use the pygments library to create a highlighted HTML
representation of the code snippet.
"""
lexer = get_lexer_by_name(self.language)
linenos = self.linenos and 'table' or False
options = self.title and {'title': self.title} or {}
formatter = HtmlFormatter(style=self.style, linenos=linenos, full=True, **options)
self.highlighted = highlight(self.code, lexer, formatter)
super(Snippet, self).save(*args, **kwargs)
class Meta:
ordering = ('created',)
根据我的理解,我可以使用以下方法绕过它:
from django.contrib.auth.models import User
from rest_framework import serializers
from snippets.models import Snippet, LANGUAGE_CHOICES, STYLE_CHOICES
class SnippetSerializer(serializers.ModelSerializer):
class Meta:
model = Snippet
owner = serializers.ReadOnlyField(source='owner.username')
fields = ('id', 'title', 'code', 'linenos', 'language', 'style')
class UserSerializer(serializers.ModelSerializer):
snippets = serializers.PrimaryKeyRelatedField(many=True, queryset=Snippet.objects.all())
class Meta:
model = User
fields = ('id', 'username', 'snippets')
但是我宁愿学点东西而不是为了做这件事。
