我正在使用带有WTforms的flask来编辑基于python-eve的API的数据 我从API中获取此对象(请密切注意' _id'以及' _etag':
{
"_updated": "Sun, 06 Apr 2014 12:49:11 GMT",
"name": "moody",
"question": "how are you?",
"_links": {
"self": {
"href": "127.0.0.1:5000/surveys/533e9f88936aa21dd410d4f1",
"title": "Survey"
},
"parent": {
"href": "127.0.0.1:5000",
"title": "home"
},
"collection": {
"href": "127.0.0.1:5000/surveys",
"title": "surveys"
}
},
"_created": "Fri, 04 Apr 2014 12:03:20 GMT",
"_id": "533e9f88936aa21dd410d4f1",
"_etag": "7d11e7f57ed306043d76c05257474670eccde91c"
}
我想在WTForm中编辑对象,所以我创建了定义表单:
class surveyForm(Form):
_id = HiddenField("_id")
_etag = HiddenField("_etag")
name = TextField("Name")
question = TextField("question")
submit = SubmitField("Send")
发起表格:
obj = getSurvey(id) # here I get the object from the API
form = surveyForm(**obj)
return render_template('surveyAdd.html', form=form)
并呈现表单:
<form class="form-horizontal" role="form" action="{{ url_for('surveyAddOrEdit') }}" method=post>
{{ form.hidden_tag() }}
{{ form._id }}
{{ form._etag }}
{{ form.name.label }}
{{ form.name(class="form-control") }}
{{ form.question.label }}
{{ form.question(class="form-control") }}
{{ form.submit(class="btn btn-default") }}
</form>
结果是:
<form class="form-horizontal" role="form" action="/survey/add" method="post">
<div style="display:none;"><input id="csrf_token" name="csrf_token" type="hidden" value="1396959127.36##dc263965e20ecc9956fc25d5b5c96f90f311cf47"></div>
<UnboundField(HiddenField, ('_id',), {})>
<UnboundField(HiddenField, ('_etag',), {})>
<label for="name">Name</label>
<input class="form-control" id="name" name="name" type="text" value="moody">
<label for="question">question</label>
<input class="form-control" id="question" name="question" type="text" value="how are you?">
<input class="btn btn-default" id="submit" name="submit" type="submit" value="Send">
糟糕......隐藏的&#39; _id&#39;领域和&#39; _etag&#39;字段不会被渲染。我只是得到一个UnboundField 请注意,下划线是条带化的,这就是问题所在。
我认为如果我可以直接从API加载对象并将其加载到表单中,并且在编辑后直接将其反馈给API,那将是最佳的......但是由于剥离的uderscores,我无法做到这一点。相反,我改变了对象 - 重命名&#39; _id&#39;到了&#39; id&#39;和&#39; _etag&#39;到了&#39; etag&#39; - 那很有效。
所以我有两个问题:
干杯!
