How do I get multiple values from checkboxes in Django
提问by NazimZeeshan
I want to get values of a multiple select check box using request.POST['xzy']as a list.
Here is my model and template code.
我想获取request.POST['xzy']作为列表使用的多选复选框的值。这是我的模型和模板代码。
My Model
我的模特
class Recommend(models.Model):
user=models.ForeignKey(User)
book=models.ForeignKey(BookModel)
friends=models.ManyToManyField(User, related_name="recommended")
My Template
我的模板
{% for friend in friends %}
<input type="checkbox" name="recommendations" id="option{{friend.id}}" value={{friend.username}} />
<label for="option{{friend.id}}"><b>{{friend.username}}</b></label><br />
{% endfor %}
My View code
我的查看代码
if request.method == 'POST':
recommendations=request.POST['recommendations']
Here I want 'recommendations' to be a list containing all friend ids but here it is just getting overwritten and only contains the value that got assigned in the last for loop iteration. How can I solve this problem. Need help desperately. Thank You.
在这里，我希望“推荐”是一个包含所有朋友 ID 的列表，但在这里它只是被覆盖，并且只包含在最后一次 for 循环迭代中分配的值。我怎么解决这个问题。迫切需要帮助。谢谢你。

if not request.POST.has_key(strName):
return ""
if request.POST[strName]:
return ','.join(request.POST.getlist(strName))
else:
return ""
