如何将数组发布到views.py [英] How to post a array to views.py

问题描述

  {item for ...在产品％} 
 
< div class =register_div> 
 
 
< p>< label for =id [{item.id}}]> {{item.Name}}< / label> < input type =textname =custom [{item.id}}]/>< / p> 
 
< / div> 
 
 {％endfor％} 
  

现在在我的意见中，我想将此数据保存到我的数据库。但是首先我检查了我的数组是否返回某些东西。我只是尝试打印为。

  q = upload_form.data ['custom []'] 
  

或

  q = upload_form.data ['custom'] 
  

但它给我这个错误

 Key'custom [] '** OR ** key custom not found in< QueryDict：{u'custom [2]'：[u's']，u'custom [1]'：[u'a']，u'price'：[你的'u''标题'：[u]'，u'customatt'：[u，u]，u'csrfmiddlewaretoken'：[u'up4Ipd5L13Efk14MI3ia2FRYScMwMJLz']}> 
  

但如果我打印此

  q = upload_form.data ['custom [1]'] 
  

那么它显示数组1的值。

所以请建议我一个更好的方法来做到这一点，我可以在我的数组中显示在views.py

解决方案

由于 upload_form.data 是一个字典，关键是'custom []'根本不存在尝试一下：

  custom_values = {} 
为key，在upload_form.data.items（）中的值： 
如果key.startswith（'custom'）：
 custom_values [key] = value 
  

字典 custom_values 现在拥有您所有的自定义表单值。

I am using for loop in my template and for different id of each record i am using arrays

{% for item in product %}

<div class="register_div">


    <p><label for="id[{{ item.id }}]">{{ item.Name }} </label> <input type="text" name="custom[{{item.id}}]"/></p>

</div>

{% endfor %}

Now when in my views i want to save this data to my database.But firstly i checked that whether my array return something or not.So i just try print that as.

q = upload_form.data['custom[]']

or

 q = upload_form.data['custom']

but it gives me this error

"Key 'custom[]' **OR** key custom not found in <QueryDict: {u'custom[2]': [u's'], u'custom[1]': [u'a'], u'price': [u''], u'title': [u''], u'customatt': [u'', u''], u'csrfmiddlewaretoken': [u'up4Ipd5L13Efk14MI3ia2FRYScMwMJLz']}>"

but if i print this

q = upload_form.data['custom[1]']

then it display the value of array 1.

so please suggest me a better way to do this how i can display all values inside my array in views.py

解决方案

As upload_form.data is a dictionary, the key 'custom[]' simply doesn't exist. Try something like:

custom_values = {}    
for key, value in in upload_form.data.items():
    if key.startswith('custom'):
        custom_values[key]=value

The dictionary custom_values holds now all your 'custom' form values.
