TemplateSyntaxError：對於函數調用表達式

無效語法我試圖燒瓶跆拳道與引導選下面結合，但我reviced TemplateSyntaxError：對於函數調用表達式TemplateSyntaxError：對於函數調用表達式

<form class="form-inline" action="/" method="POST" role="form"> 
<div class="input-group"> 
    {{ form.hidden_tag() }} 
    <span class="input-group-addon">Make:</span> 
    {{ form.make(id="make_select", class="selectpicker form-control", data-live-search="true") }} 
    <span class="input-group-addon">Model:</span> 
    {{ form.model(id="model_select", class="selectpicker form-control", data-live-search="true") }} 

    <span class="input-group-btn"> 
    <button class="btn btn-default" type="submit">Search!</button>

無效的語法。

TemplateSyntaxError: invalid syntax for function call expression

。

from flask.ext.wtf import Form 
from wtforms import SelectField 


class VehicleForm(Form): 
    make = SelectField(u'', choices=()) 
    model = SelectField(u'', choices=())

爲什麼數據實時搜索「=」 true」是造成TemplateSyntaxError

[使用工具提示與Jinja2錯誤]可能的重複（http://stackoverflow.com/questions/24868098/error-using-tooltips-with-jinja2） – 2014-10-03 14:46:01

看看這個片斷：http://flask.pocoo.org/snippets/107/

在你的情況下更換：

{{ form.make(id="make_select", class="selectpicker form-control", data-live-search="true") }}

通過

{{ form.make(id="make_select", class="selectpicker form-control", **{'data-live-search':'true'}) }}
