在Django模板中的列表内访问字典值 [英] Access Dictionary Value inside list in Django Template

问题描述

我在列表中有一本字典.我想在Django模板中访问字典值.我该怎么办?views.py

I have a dictionary inside a list. I want to access dictionary value inside django template. How can I get that? views.py

def payment_status(request):
    l1=[]
    cand = CandidateDetail.objects.all()


    for person in cand:
        for num in range(0,paid['count']):
            if paid['items'][num]['email']==person.email and paid['items'] 
            [num]['status']=='authorized':
                cand_dict = {'first_name':person.first_name, 
                'last_name':person.last_name, 'email':person.email, 
                 'paid':'Yes'}
                l1.append(cand_dict)


    return render(request, 'desk/payment_status.html',{'cand_list':l1})

html文件

<div class="col-md-10">
      <h3>Candidate Payment Status</h3>
      <table class="cand_list">
        <tr>
          <th>Name</th>
          <th>Email</th>
          <th>Payment Status</th>
        </tr>

        {% for candidate in cand_list %}
      <tr>
        <td>{{ candidate.first_name }} {{ candidate.last_name }}</td>
        <td>{{ candidate.email }}</td>
        <td>{{ candidate.paid }}</td>
      </tr>
    {% endfor %}
      </table>
</div>

我遇到的错误是-无法解析剩余的:'cand_list [item] ['first_name']'中的'[item] ['first_name']'

推荐答案

一开始，在某些长度范围内进行迭代从来都不是正确的事-无论是在Python中还是在模板.

For a start, iterating over a range of the length of something is never the right thing to do - either in Python or in a template.

第二，在Django模板语言中，即使是字典键，也总是使用点表示法.

Secondly, in Django template language you always use dot notation, even for dictionary keys.

所以，在您看来:

for person in cand:
    for item in paid['items']:
        if item['email']== person.email and item['status']=='authorized':
             ....

并在您的模板中:

    {% for item in cand_list %}
    <tr>
      <td>{{ item.first_name }} {{ item.last_name }}</td>
      <td>{{ item.email }}</td>
      <td>{{ item.paid }}</td>
    </tr>
    {% endfor %}
