python - 使用 GET 而不是 POST 提交 Wtform

Question

我正在尝试使用 wtforms、flask 和 bootstrap 制作一个简单的表单，但我的表单提交导致 GET 和表单参数而不是 POST。

我只用 flask 就让它工作了，但是当我切换到从 flask.ext.wtf 导入表单时，使用 form.validate_on_submit 而不是仅仅验证，并使用 flask_bootstrap，但现在提交表单会导致 GET 操作而不是一个 POST Action 。我错过了什么？

这是我在控制台中看到的内容:

GET
127.0.0.1 - - [14/Apr/2014 21:04:10] "GET / HTTP/1.1" 200 -
GET
127.0.0.1 - - [14/Apr/2014 21:04:13] "GET /?csrf_token=None&recipe1=dfsaasdf&recipe2=adfsadfs&submit_button=Submit+Form HTTP/1.1" 200

这是我的完整应用:

from flask import render_template, request, redirect, url_for
from flask.ext.wtf import Form
from wtforms.ext.csrf import SecureForm
from wtforms import TextField, HiddenField, ValidationError, RadioField,\
    BooleanField, SubmitField, IntegerField, FormField, validators
from concat.recipe_concatenator import RecipeConcatenator

from flask_bootstrap import Bootstrap
from flask import Flask
from hashlib import md5

app = Flask(__name__)
Bootstrap(app)
app.config['DEBUG'] = True
SECRET_KEY = '1234567890'

class RecipeCompareForm (Form):
    recipe1 = TextField('Recipe 1', [])
    recipe2 = TextField('Recipe 2')
    submit_button = SubmitField('Submit Form')

@app.route('/', methods=['GET', 'POST'])
def compare():
    print request.method
    form = RecipeCompareForm(csrf_enabled=False)
    if form.validate_on_submit():
        print "validated"
        print form.recipe1.data
    message = "blah"
        return redirect(url_for('results', message=message))
    return render_template('form.html', form=form)

@app.route('/results')
def results():
    message = request.args['message']
    return render_template('results.html', message=message)

if __name__ == '__main__':
    app.run()

模板:

{% extends "bootstrap/base.html" %}

{% import "bootstrap/wtf.html" as wtf %}
{% import "bootstrap/fixes.html" as fixes %}
{% block content %}
<form class="form form-horizontal" role ="form">

  {{ form.hidden_tag() }}
  {{ wtf.form_errors(form, hiddens="only") }}
  {{ wtf.form_field(form.recipe1) }}
  {{ wtf.form_field(form.recipe2) }}
  {{ wtf.form_field(form.submit_button) }}
</form>
{% endblock %}

如果您没有指定method 属性，则表单默认为GET。要使用 POST，请将 method 属性添加到您的表单标记中，如下所示:

<form class="form form-horizontal" role="form" method="POST">
