Question

尝试使用flask-bootstrap quick_form。

HTML模板my-form.j2：

{% import "bootstrap/wtf.html" as wtf %}
{% extends "layout.j2" %}

{% block content %}

<h1>My form</h1>
{{ wtf.quick_form(form) }}

{% endblock content %}

表格类：

class MyForm(FlaskForm):
    """A WTForm for configuring vehicle information"""
    field1 = StringField('First field', [wtforms.validators.required()])
    field2 = StringField('Second field', [wtforms.validators.required()])
    field3 = StringField('Third field', [wtforms.validators.required()])

表单处理程序：

@app.route('/myform', methods=('GET', 'POST'))
def my_form():
    form = MyForm()
    if form.validate_on_submit():
        myData = form.data
        return redirect("/")
    return render_template("my-form.j2", form=form)

不幸的是，我没有看到呈现提交按钮，即使我添加了 {{ form.submit }}到我的桌子。有什么想法吗？

@atwalsh的答案工作得很好，但你也可以把你的提交按钮放在你的课堂上，然后在你的模板中调用它：

class MyForm(FlaskForm):
    field1 = StringField('First field', [wtforms.validators.required()])
    field2 = StringField('Second field', [wtforms.validators.required()])
    field3 = StringField('Third field', [wtforms.validators.required()])
--> submit_button = SubmitField('Submit Form')

然后输入你的模板：

{{ wtf.quick_form(form, button_map={'submit_button': 'primary'}) }}
                            ^            ^

Answer 2

我相信您可以在{{ wtf.quick_form(form) }}之后直接添加输入字段，并将这两个字段放在HTML表单中：

<input class="btn btn-primary" type="submit" value="Login">

示例

{% import "bootstrap/wtf.html" as wtf %} {% extends "layout.j2" %} {% block content %} <h1>My form</h1> <form method="POST" action="/"> {{ wtf.quick_form(form) }} <input class="btn btn-primary" type="submit" value="Login"> </form> {% endblock content %}

flask-bootstrap quick_form缺少提交按钮
