所以，我是django的新手，我想要实现的是在bootstrap模式中编辑注释。 我的问题是，当我启动模态以编辑特定注释时，注释文本不会以模态显示。我使用相同的CommentForm类来创建和编辑注释，因为我对我的应用程序中的其余模型类使用相同的原则。
以下是编辑评论视图：
def edit_comment(request, p_id):
comment = get_object_or_404(Comment, pk=p_id)
task_id = comment.task.id
task = get_object_or_404(Task, pk=task_id)
if request.method == "POST":
form = CommentForm(request.POST, instance=comment)
if form.is_valid():
form.save()
return redirect(reverse('task_details', kwargs={'p_id' : task.id}))
else:
data = {
'form' : CommentForm(instance=comment),
}
return render(request, "polls/task_details.html",data)
因为附加到任务的所有注释的列表都显示在任务详细信息中，这是我启动编辑模式的地方，这里是视图：
def task_details(request, p_id):
projects = Project.objects.filter(users=request.user)
task = get_object_or_404(Task, pk=p_id)
comments = Comment.objects.filter(task__id=p_id)
proj_id = task.project.id
project = get_object_or_404(Project, pk=proj_id)
if request.method == "POST":
data = {'task': task,
'comments': comments,
'project' : project,
'form' : CommentForm(),
'projects' : projects}
form = CommentForm(request.POST)
if form.is_valid():
comment = form.save(commit=False)
comment.user = request.user
comment.type = "comment"
comment.task = task
comment.save()
return render(request, "polls/task_details.html", data)
else:
data = {'task': task,
'comments': comments,
'project' : project,
'form' : CommentForm(),
'projects' : projects}
data.update(csrf(request))
return render(request, "polls/task_details.html", data)
forms.py：
class CommentForm（ModelForm）：
class Meta:
model = Comment
fields = ('comment_text',)
exclude = ('user', 'time_occurred', 'type', 'task', 'milestone')
widgets = {'comment_text': forms.Textarea(attrs={'class':"form-control",
'required':"",
'rows':3,
})}
labels = {"comment_text": _("Comment"),
}
urls.py：
url(r'^edit_comment/(?P<p_id>\d+)/$', views.edit_comment, {}, 'edit_comment'),
注释附加到Task，而Comment继承了LogEvent抽象类，所以这里是models.py部分：
class Task(models.Model):
project = models.ForeignKey(Project)
user = models.ForeignKey(User, related_name='task_created_by')
assigned = models.ForeignKey(User, related_name='task_assigned_to', null=True)
priority = models.ForeignKey(Priority,null=True)
milestone = models.ForeignKey(Milestone)
name = models.CharField(max_length = 50)
description = models.CharField(max_length = 5000)
type = models.ForeignKey(Type, null=True)
state = models.CharField(max_length = 20, choices = State)
def __str__(self):
return self.name
class LogEvent(models.Model):
user = models.ForeignKey(User)
time_occurred = models.DateTimeField('time_occurred')
type = models.CharField(max_length = 50)
task = models.ForeignKey(Task, null=True, blank=True)
milestone = models.ForeignKey(Milestone, null=True, blank=True)
class Meta:
abstract = True
class Comment(LogEvent):
comment_text = models.TextField()
def save(self, *args, **kwargs):
''' On save, update timestamps '''
if not self.id:
self.time_occurred = datetime.datetime.today()
return super(Comment, self).save(*args, **kwargs)
def __str__(self):
return self.user.username
最后，模板： （这是任务详细信息模板的一部分，其中显示了附加到特定任务的所有注释）
<div class="col-lg-12">
{% for comment in comments %}
<div class="well">
<p>
<i class="fa fa-fw fa-user"></i><a href="" style="color: #424242"><strong>{{comment.user.get_full_name}}</strong></a>
<i class="fa fa-fw fa-clock-o"></i>{{comment.time_occurred}}
{% if comment.user == user %}
<a href=""
class="btn btn-info btn-xs btn-outline"
style="float: right; margin-left: 5px" data-toggle="modal" data-target="#EditModal{{forloop.counter}}"> <i class="fa fa-fw fa-edit"></i> Edit</a>
<!-- EDIT MODAL -->
<div class="modal fade" id="EditModal{{forloop.counter}}" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog" >
<div class="modal-content" style=" border-color: #5cb85c;">
<div class="modal-header" style=" color: white;background-color: #5cb85c;border-color: #5cb85c;">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h4 class="modal-title" id="myModalLabel" >Edit comment</h4>
</div>
<form action="{% url 'edit_comment' p_id=comment.id %}" method="post">
{% csrf_token %}
{% for field in form %}
<div class="modal-body">
{{field.errors}}
{{field}}
</div>
{% endfor %}
<div class="modal-footer">
<button type="button" class="btn btn-default btn-outline" data-dismiss="modal">Close</button>
<input type="submit" class="btn btn-success btn-outline" value="Save changes">
</div>
</form>
</div>
<!-- /.modal-content -->
</div>
<!-- /.modal-dialog -->
</div>
{% endif %}
<p>{{comment.comment_text}}</p>
</div>
{% endfor %}
</div>
我的问题是我应该怎么做才能在模态中的textarea中显示评论文本，或者我错过了什么，这样用户可以轻松地修改他的评论，而不是在发布模态之前复制文本？
