分配css类以形成从flask传递到jinja的元素

问题描述

我对Jinja/flask很陌生，正在我的flask应用程序中创建动态表单:

I am quite new to jinja / flask, I am creating dymnamic form in my flask app:

class CreateForm(FlaskForm):
    searchCity = StringField('View forcast of city:', validators=[InputRequired("Please enter the city you want to check weather updates")])
    count = IntegerField("Days")
    submit = SubmitField("Submit")


form = CreateForm(request.form)
form.count.default = count
form.count.label = "Days" if count > 1 else "Day" 

form.count.data = count

和在jinja模板中:

and in jinja template:

<form>
    <dl>
        <dd>{{ form.searchCity.label }} {{ form.searchCity(size=20) }} 
            for next {{ form.count(size=2) }} {{ form.count.label }}
            <input type="submit" class="btn-primary" value="Submit" id="calculate" onclick="getWeatherForcaset(
            document.getElementsByName('searchCity')[whole_number].value,
            document.getElementsByName('count')[whole_number].value
            );" >
        </dd>
        <dd>
            <input type="checkbox" name="exactMatch" checked="checked">Exact Match 
            &nbsp;
            <input type="checkbox" name="remember">Remember<br/ >
        </dd>

    </dl>
 </form>

我想将类form-group分配给searchCity输入框！任何帮助将不胜感激，谢谢

I want to assign class form-group to searchCity inputbox !any help would be greatly appreciated thanks

推荐答案

您应该能够像这样将变量传递到构造函数中

You should be able to pass variables into the constructor like so

{{ form.searchCity(size=20, class_='searchCity') }}  

可在以下位置找到文档:

Documentation is available at :

http://wtforms.readthedocs.io/en/latest /crash_course.html#rendering-fields

文档片段

form.content(style ="width:200px;"，class _ ="bar")

form.content(style="width: 200px;", class_="bar")

<input class="bar" id="content" name="content" style="width: 200px;" type="text" value="foobar" />'
