每次我使用UpdateView并尝试更改某些属性时,它会使用新的唯一主键在我的数据库中创建一个新对象。我的模型如下。
class Delivery(models.Model):
created_date = models.DateTimeField('date created', editable=False)
modified_date = models.DateTimeField('modified', editable=False)
user_name = models.ForeignKey(User, null=False)
stream_name = models.CharField(max_length=50, null=False)
view_name = models.CharField(max_length=100, null=False, blank=True)
activity_name = models.CharField(max_length=100, null=False, blank=True)
jira = models.URLField()
codereview = models.URLField()
related_streams = models.CharField(max_length = 100, choices=sorted(streams()))
description = models.TextField(null=False,blank=True)
status = models.BooleanField(default=False, blank=False)
class Meta:
verbose_name = "Delivery"
verbose_name_plural = "Deliveries"
unique_together = (("user_name", "view_name", "activity_name"),)
对于我正在使用ModelFactoryForm的表单,UpdateView默认使用它来使用模型本身挑选一个form_class。
class UpdateEntryView(UpdateView):
template_name = 'tracker/update.html'
model = Delivery
success_url = reverse_lazy('table_view')
status = StreamStatus()
fields = ['stream_name','view_name','activity_name','jira','related_streams','description','status']
def get_context_data(self, **kwargs):
ctx = super(UpdateEntryView, self).get_context_data(**kwargs)
ctx['locked'] = self.status.getLocked()
ctx['unlocked'] = self.status.getUnlocked()
return ctx
HTML模板如下:
...
{% block content %}
<form action="/tracker/entry/" method="post" class="form">
{% csrf_token %}
<div class="form-goup">
<div class="panel panel-default">
<div class="panel-heading">Enter the codereview link and let the machine do the work for you ...</div>
<div class="panel-body">
<div class="input-group">
<i class="glyphicon glyphicon-link input-group-addon" aria-hidden="true"></i>
<input type="text" class="form-control" name="codereview" placeholder="Codereview link">
</div>
</div>
</div>
<hr>
<div class="panel panel-default">
<div class="panel-heading">Add an entry manually ...</div>
<div class="panel-body">
{% bootstrap_form form %}
</div>
</div>
<hr>
{% buttons %}
<button type="submit" class="btn btn-primary btn-block">
{% bootstrap_icon "lock" %} Submit
</button>
{% endbuttons %}
</div>
</form>
{% endblock %}
...
这是UpdateView中的一个缺陷还是我自己的一些事情搞砸了。
答案 0 :(得分:3)
您的网址是否可能指向CreateView而不是UpdateView?
答案 1 :(得分:2)
模板中的行会将其发布到&#34; / tracker / entry /&#34; url,没有指定PK,我认为这是导致你问题的原因。
更新视图应在URL中包含PK,id或slug,因此Django知道要更新的对象。
删除网址,然后POST回到与GET相同的位置。
<form action="" method="post" class="form">
