[英]WTForms, how to attach JSON data to the request
I'm bulding a form with WTForms for a Flask application. 我正在为Flask应用程序构建带有WTForms的表单。 This form's las field is an address field that works with google PlacesAPI, so it autocompletes the address the user is introducing in that field.
此表单的las字段是与Google PlacesAPI一起使用的地址字段,因此它将自动完成用户在该字段中介绍的地址。
I want to be able to save all the data this PlacesAPI generates when the user selects an address, but I'm struggling to find a proper way to send that data to the server. 我希望能够保存用户选择地址时此PlacesAPI生成的所有数据,但是我一直在努力寻找将数据发送到服务器的正确方法。
I have a Flask with MongoDB as backend. 我有一个MongoDB作为后端的烧瓶。
What I have tried 我尝试过的
I submited the form with Jquery Ajax method, I validated it by adding WTF-JSON to my project, it monkeypatches the Form class and some methods so it can process JSON as ***kwargs. 我使用Jquery Ajax方法提交了表单,并通过在项目中添加WTF-JSON对其进行了验证,它对Form类和某些方法进行了修补,因此它可以将JSON处理为***。
Problem : this leaves me without being able to easily redirect the user on form validation. 问题 :这使我无法轻松地重定向用户进行表单验证。
I can add a hidden input field where I add all the address JSON as a string and then process it in my backend 我可以添加一个隐藏的输入字段,在其中将所有地址JSON添加为字符串,然后在后端处理它
Problem : Somehow this simes hacky, I was wondering if there is a better way 问题 :不知何故,这很奇怪,我想知道是否有更好的方法
Question 题
What would be the right way to do this? 正确的方法是什么? It's the first time I've tried, so I'm pretty sure there must be a way I'm missing here.
这是我第一次尝试,所以我很确定这里一定有我所缺少的方法。 Thanks a lot for all your help.
非常感谢您的所有帮助。
Option # 1 is the best option considering the scenarios you have explained. 考虑到您所说明的方案,选项1是最佳选择。 There should not be any problems in re-directing the user to form validation page as you can manage it through XHR.
将用户重定向到表单验证页面应该没有任何问题,因为您可以通过XHR对其进行管理。 Here is what I can suggest
这是我的建议
@catalog.route('/')
@catalog.route('/your_page')
def home():
if request.is_xhr:
## Here you can call the def and store the addresses
addresses = Address.query.all()
json_addresses jsonify({'addresses': addresses)})
return render_template('your_form_page.html', json_addresses)
While rendering the template page you pass few more parameters such as validation messages. 呈现模板页面时,您传递了更多的参数,例如验证消息。
Please use is_xhr
as per the need of your functionality but I recommend it. 请根据您的功能需要使用
is_xhr
,但我建议您使用它。
