Django“如果request.method =='POST'：”失败

Question

您好，在我的新 Django 项目中有一个奇怪的问题。

我基本上是在测试Django Documentation Working with Froms 中的 NameForm 示例。这似乎很简单，但不知何故，当我尝试提交一些名称时，即使没有重新加载页面，也没有任何反应。

form.py

from django import forms

class NameForm(forms.Form):
     your_name = forms.CharField(label='Your name', max_length=100)

views.py

from django.shortcuts import render
from django.http import HttpResponseRedirect
from groupbuilder import forms

def GroupBuilder(request):
    if request.method == 'POST':
        form = forms.NameForm(request.POST)
        if form.is_valid():
            return HttpResponseRedirect('/thanks/')

    else:
        form = forms.NameForm()


    return render(request, 'groupbuilder.html', {'form': form})

模板：

    <form action="/your-name/" method="post">
          {% csrf_token %}
          { form.as_p }}
          <input type="submit" value="Submit" />
    </form>

奇怪的是如果我把

return HttpResponseRedirect('/thanks/')

就在“else”之后

if request.method == 'POST':

声明，当我尝试访问表单 URL 时，我什至无法填写表单。它把我直接带到/thanks/。所以 request.method 检查总是失败。

我错过了什么？？

Answer 1

问题解决了：

<script src="{{STATIC_URL}}js/plugins/jqBootstrapValidation.js"></script>

来自jqBootstrapValidation 导致了这个问题。我不太清楚为什么，但一定是某些表单功能受到了干扰。

谢谢你的帮助

Answer 2

您的模板代码中有错误：{ form.as_p }} add '{'

Answer 3

我尝试了以下方法：

如果表单域是

your_name = forms.CharField(label='Your name', max_length=5, required = True)

我只是点击提交按钮而不填写名称，没有任何反应。没有重新加载页面，没有错误消息（因为该字段设置为“必填”）。

如果我将字段定义为

your_name = forms.CharField(widget=forms.TextInput(attrs=dict(required=True, max_length=30)), label=("our name"))

我点击了无名提交，但确实收到 Django 表单字段错误
