我正在创建一个表单,但出于某种原因,每当我尝试验证它时,它总是返回False。
形式:
class AddStuffForm(Form):
myList = [(idx,int(val.tier)) for idx,val in enumerate(getList())]
myList.remove((2,3)) # this is an element I don't want in the list
myListForm = SelectField("List:", [Required()], choices=myList)
def __init__(self, *args, **kwargs):
""" Constructor. """
Form.__init__(self, *args, **kwargs)
self.user = None
def validate(self):
""" Validates registration form. """
rv = Form.validate(self)
if not rv:
return False
查看:
@app.route('/addStuff', methods=['GET', 'POST'])
def addStuff():
""" Submits register form. """
form = AddStuffForm()
if form.validate_on_submit():
return redirect(url_for('addStuff'))
return render_template('/AddStuff.html', form=form)
AddStuff.html:
{% extends "layout.html" %}
{% block content %}
<h1>Add stuff</h1>
<form method="POST" action="{{ url_for('addStuff') }}">
{{ form.hidden_tag() }}
<p>{{ form.myListForm.label }} {{ form.myListForm(size=1) }}</p>
<input type="submit" value="Add it">
</form>
{% endblock %}
在查找问题时,我唯一能找到的就是确保“{{form.hidden_tag()}}”在html中,但正如您所看到的,我已经拥有了。我错过的SelectField是否有错误?
答案 0 :(得分:0)
决定只删除&#34;如果不是rv:返回False&#34;位。如果背景中出现任何问题,那么哦。
