我的反馈论坛类型的网络应用程序有一个可用的编辑表单,但我无法弄清楚如何使帖子的内容出现在编辑表单中。我希望用户点击“编辑”并转到编辑反馈网址,并在表单中显示反馈帖的标题和正文。我正在使用Django,但我找不到任何关于如何实现这一目标的文档。
这是forms.py
class EditFeedbackForm(forms.Form):
title = forms.CharField(label='Title')
body = forms.CharField(label='Body', widget=forms.Textarea)
edit_feedback
中的 views.py
视图
def edit_feedback(request, feedback_id, board):
boardObj = Board.objects.get(board_name=board)
boardGroups = boardObj.groups.all()
userGroups = request.user.groups.all()
userBoardAccess = False
boardFeedbacks = Feedback.objects.filter(feedback_board=boardObj.id)
userFeedbacks = Feedback.objects.filter(feedback_user=request.user.profile.id)
print boardFeedbacks
for group in boardGroups:
if group in userGroups:
userBoardAccess = True
break
if not userBoardAccess:
messages.error(request, 'Cannot view a board you are not a member of.')
return boards(request)
post = Feedback.objects.get(id=feedback_id)
form = EditFeedbackForm()
if post.feedback_user == request.user.profile:
if request.method == 'POST':
form = EditFeedbackForm(request.POST)
if form.is_valid():
title = form.cleaned_data['title']
body = form.cleaned_data['body']
post.feedback_title = title
post.feedback_description = body
post.feedback_last_modified = datetime.now()
post.save(update_fields=['feedback_title', 'feedback_description', 'feedback_last_modified'])
print "saved feedback " + str(post.id)
else:
form = EditFeedbackForm()
else:
messages.error(request, 'Cannot edit a post you did not write.')
return redirect('/board/' + board + '/')
return render(request, 'app/edit_feedback.html', {'form': form, 'board': boardObj.board_name, 'boardid': boardObj.id, 'boardObj': boardObj, 'feedback': post, 'userFeedbacks': userFeedbacks})
edit_feedback.html
模板
{% extends 'app/base.html' %}
{% load i18n widget_tweaks %}
{% load board_extras %}
{% block content %}
<div id="body-wrapper">
<h1><a id="undecorated" href="/board/{{board}}">{{board}}</a></h1>
<!-- show current feedback -->
<div style="margin-left: 50px;">
<h4>{{feedback.feedback_title}} | {{feedback.feedback_last_modified }}</h4>
<h5>{{ feedback.feedback_description }}</h5>
</div>
<!-- edit form -->
<form role="form" action="" method="post">

{% for field in form %}

<div class="col-sm-10">

{% if field.help_text %}
<p class="help-block"><small>{{ field.help_text }}</small></p>
{% endif %}
</div>
</div>
{% endif %}
{% endfor %}
<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">
<button type="submit" class="btn btn-primary" value="Save">{% trans "Save" %}</button><br>

我目前的工作是在页面顶部显示原始帖子,以便用户可以复制并粘贴到表单中进行更改,但显然这并不理想。

您可以使用Django的Generic Update View。
,而不是自己构建表单 来自文档的片段:
一个视图,显示用于编辑现有对象的表单,重新显示包含验证错误的表单(如果有)并保存对象的更改。这使用从对象的模型类自动生成的表单(除非手动指定表单类)。
在上面链接的文档中甚至有足够的例子。
