Django表单不呈现 [英] Django form doesn't render

问题描述

你好，谢谢你提前。我有一个没有渲染在模板上的django表单。 提交按钮呈现，但表单不显示。我一直盯着这段代码约6个小时，可能是很简单的事情，我可能需要另外一双眼睛。

我的模型：

 ＃models.py 
 
 from django.db import models 
 from django.forms import ModelForm 
 
 class DraftInput（models.Model）：
 player_id = models.IntegerField（help_text ='Input Player ID Number'，max_length = 5）
 
 def __unicode __（self ）
 return self.player_id 
 
 class DraftForm（ModelForm）：
 class Meta：
 model = DraftInput 
  / pre> 
 
 
我的意见：
 ＃views.py 
 
 from django.shortcuts import render_to_response 
 
 from simple.models import DraftInput 
 from simple.models import DraftForm 
 
 from django.template import RequestContext 
 
＃... 
 
 def draft_view（request）：
 
如果request.method =='POST'：
 form =博士aftForm（request.POST）
如果form.is_valid（）：
 form.save（）
 else：
 form = DraftForm（）
 
 return render_to_response（'simple / draft_input.html'，{'form'：form}）
  
我的模板： 
 ＃draft_input.html 
 
＃... 
 
< h1>草稿输入< / h1> 
< h2> Draft< / h2>< br />< br /> 
< form method =POSTaction => 
< table> {{form}}< / table> 
< input type =submitvalue =Draft Player/> 
< / form>< br />< br /> 
＃... 
  
感谢您的帮助。
解决方案
阅读答案的线程，似乎还是没有运气。
 
 
 
尝试执行这些命令在django交互式shell（ python manage.py shell ）中。当您尝试格式化表单时，可能会抛出异常。当模板中的表单生成期间抛出异常时，HTML中看不到太多;但是一个django shell通常会揭示罪魁祸首。
  python manage.py shell 
 
在[1] ：from simple.models import DraftForm 
 
在[2]中：form = DraftForm（）
 
在[3]中：form.as_p（）
  
您可以查看此处生成的HTML，也可能会捕获异常。这将告诉您更多关于您需要修复的内容。
 
Hello and thank you in advance.  I have a django form that is not rendering on a template.  The "submit" button renders, but the form doesn't. I have been staring at this code for about 6 hours and it is probably something very simple, I probably need another pair of eyes on it.

My Model:
#models.py

from django.db import models
from django.forms import ModelForm

class DraftInput(models.Model):
    player_id = models.IntegerField(help_text = 'Input Player ID Number', max_length = 5)

    def __unicode__(self):
        return self.player_id

class DraftForm(ModelForm):
    class Meta:
        model = DraftInput 
My views:
#views.py

from django.shortcuts import render_to_response

from simple.models import DraftInput
from simple.models import DraftForm

from django.template import RequestContext

#...    

def draft_view(request):

    if request.method == 'POST':
        form = DraftForm(request.POST)
        if form.is_valid():
            form.save()
    else:
        form = DraftForm()

    return render_to_response('simple/draft_input.html', {'form': form} )
My template:
#draft_input.html

#...

        <h1>Draft Input</h1>
        <h2>Draft</h2><br /><br />
            <form method="POST" action="">
            <table>{{ form }}</table>
            <input type="submit" value="Draft Player" />
        </form><br /><br />
#...
Thank you for your help.
解决方案
Reading the answers thread, it seems you're still out of luck.

Try performing these commands in a django interactive shell (python manage.py shell). It's possible that an exception is thrown when you try to format the form. When an exception is thrown during the form generation in the template, you won't see much in the HTML; but a django shell usually unveils the culprit.
python manage.py shell

In [1]: from simple.models import DraftForm

In [2]: form = DraftForm()

In [3]: form.as_p()
You can either see the HTML generated here, or would catch an exception. This will tell you more about what you need to fix.
