我是Django的新手,所以不要评判我:)。我正在制作一个博客项目,一切都很顺利,除了一件事。创建帖子时,用户可以选择之前登录过的任何其他作者。有没有办法将作者名称空间设置为当前登录的用户?这是我的代码:
#!/usr/bin/env python
import pika
connection = pika.BlockingConnection(pika.ConnectionParameters(host='localhost'))
channel = connection.channel()
channel.queue_declare(queue='hello')
def callback(ch, method, properties, body):
print(" [x] Received %r" % body)
channel.basic_consume(callback,
queue='hello',
no_ack=True)
print(' [*] Waiting for messages. To exit press CTRL+C')
channel.start_consuming()
我的forms.py
Models.py
from django.db import models
from django.utils import timezone
from django.core.urlresolvers import reverse
from django.core.exceptions import ValidationError
from django.utils.translation import gettext_lazy as _
from django.contrib.auth.models import User
def validate_even(value):
if value == 'auth.User':
raise ValidationError(
_('%(value)s is not an even number'),
params={'value': value},
)
class Post(models.Model):
author = models.ForeignKey('auth.User')
title = models.CharField(max_length=200)
text = models.TextField()
created_date = models.DateTimeField(default=timezone.now)
published_date = models.DateTimeField(blank=True,null=True)
def publish(self):
self.published_date = timezone.now()
self.save()
def approve_comments(self):
return self.comments.filter(approved_comment=True)
def get_absolute_url(self):
return reverse('post_detail', args=(), kwargs={'pk':self.pk})
def __str__(self):
return self.title
class Comment(models.Model):
post = models.ForeignKey('blog.post',related_name='comments')
author = models.ForeignKey('auth.User')
text = models.TextField()
created_date = models.DateTimeField(default=timezone.now)
approved_comment = models.BooleanField(default=False)
def approve(self):
self.approved_comment = True
self.save()
def get_absolute_url(self):
return reverse('post_list')
def __str__(self):
return self.text
class UserProfileInfo(models.Model):
user = models.OneToOneField(User)
def __str__(self):
return self.user.username
我的views.py
from django import forms
from blog.models import Comment,Post
from django.contrib.auth.models import User
from blog.models import UserProfileInfo
class PostForm(forms.ModelForm):
class Meta():
model = Post
fields = ['author','title','text']
widgets = {
'title':forms.TextInput(attrs={'class':'textinputclass','autocomplete':'true'}),
'text':forms.Textarea(attrs={'class':'editable medium-editor-textarea postcontent'})
}
class CommentForm(forms.ModelForm):
class Meta():
model = Comment
fields = ['text']
widgets = {
'text':forms.Textarea(attrs={'class':'editable medium-editor-textarea'})
}
def __init__(self, *args, **kwargs):
from django.forms.widgets import HiddenInput
hide_condition = kwargs.pop('hide_condition',None)
super(CommentForm, self).__init__(*args, **kwargs)
if hide_condition:
self.fields['author'].widget = HiddenInput()
class UserForm(forms.ModelForm):
password = forms.CharField(widget=forms.PasswordInput(attrs={'autocomplete':'false'}))
username = forms.CharField(widget=forms.TextInput(attrs={'autocomplete': 'false'}))
class Meta():
model = User
fields = ('username', 'email', 'password')
widgets = {
'password':forms.TextInput(attrs={'autocomplete':'false'}),
'username':forms.TextInput(attrs={'autocomplete':'false'}),
}
我已经尝试过一切,没有任何效果。有人可以帮帮我吗?
答案 0 :(得分:1)
在PostForm
中,从字段中删除author
,以便用户无法对其进行编辑:
fields = ['title', 'text']
然后在CreatePostView
中删除def get_queryset()
方法,因为它不会在此处执行任何操作。您应该覆盖form_valid
方法,在那里您有机会更新表单创建的模型。
def form_valid(self, form):
self.object = form.save(commit=False) # the form's save method returns the instance
self.object.author = self.request.user # here you assign the author
self.object.save()
return HttpResponseRedirect(self.get_success_url())
或者,尽可能接近CreateView
父类:
def form_valid(self, form):
form.instance.author = self.request.user
return super().form_valid(form) # this will call `CreateView`'s `form_valid()` method, which saves the form.
