Python Django如何循环对象并在模板中显示变量
我正在使用boto3在AWS中显示有关s3存储桶的各种数据。 我在views.py中有以下代码来显示s3页面:Python Django如何循环对象并在模板中显示变量,python,django,amazon-web-services,amazon-s3,Python,Django,Amazon Web Services,Amazon S3,我正在使用boto3在AWS中显示有关s3存储桶的各种数据。 我在views.py中有以下代码来显示s3页面: class s3(TemplateView): template_name = 'project/s3.html' def get_context_data(self, **kwargs): context = super(s3, self).get_context_data(**kwargs) aws = boto3.reso
class s3(TemplateView):
template_name = 'project/s3.html'
def get_context_data(self, **kwargs):
context = super(s3, self).get_context_data(**kwargs)
aws = boto3.resource('s3')
buckets = aws.buckets.all()
for bucket in buckets:
totalSize = 0
bucketName = bucket.name
createdAt = bucket.creation_date
fileBuckets = boto3.resource('s3').Bucket(bucketName)
for file in fileBuckets.objects.all():
totalSize += file.size
context['buckets'] = buckets
context['bucket'] = buckets
context['createdAt'] = createdAt
context['bucketName'] = bucketName
context['totalSize'] = totalSize
return context
我试图在这样的模板中显示这些变量:
<div class="s3Items">
{% for bucket in buckets %}
<div class="s3Name">
<div id="left">
<h4 id='s3ItemName'>{{ bucketName }}</h4>
</div>
<div id="right">
<ul id='s3ItemDesc'>
<li>{{ createdAt }}</li>
<li>{{ totalSize }}/4GB</li>
<li>
<button type="button" name="button" class='button delete'>Delete</button>
</li>
</ul>
</div>
</div>
{% endfor %}
{bucket%中的bucket为%1}
{{bucketName}}
- {{createdAt}}
- {{totalSize}}/4GB
-
删除
{%endfor%}
但很明显,这是行不通的。如何在模板中遍历这些桶?
我还尝试了以下方法,但效果并不完全,因为我无法获得每个存储桶中所有文件的总大小:
<div class="s3Items">
{% for bucket in buckets %}
<div class="s3Name">
<div id="left">
<h4 id='s3ItemName'>{{ bucket.name }}</h4>
</div>
<div id="right">
<ul id='s3ItemDesc'>
<li>{{ bucket.creation_date}}</li>
<li>{{ ??? }}/4GB</li>
<li>
<button type="button" name="button" class='button delete'>Delete</button>
</li>
</ul>
</div>
</div>
{% endfor %}
{bucket%中的bucket为%1}
{{bucket.name}
- {{bucket.creation_date}
- {{???}}/4GB
-
删除
{%endfor%}
我可以在模板内创建一个新循环吗?或者我应该在python文件中创建它并在模板中调用它?我该怎么做?
谢谢您可以创建字典列表,然后可以在模板中迭代列表
class s3(TemplateView):
template_name = 'project/s3.html'
def get_context_data(self, **kwargs):
context = super(s3, self).get_context_data(**kwargs)
data = []
aws = boto3.resource('s3')
buckets = aws.buckets.all()
for bucket in buckets:
bucket_data = {}
totalSize = 0
fileBuckets = boto3.resource('s3').Bucket(bucketName)
for file in fileBuckets.objects.all():
totalSize += file.size
bucket_data['bucketName'] = bucket.name
bucket_data['createdAt'] = bucket.createdAt
bucket_data['totalsize'] = totalSize
data.append(bucket_data)
context['buckets'] = data
return context
现在,在模板中,您可以迭代变量“bucket”
<div class="s3Items">
{% for bucket in buckets %}
<div class="s3Name">
<div id="left">
<h4 id='s3ItemName'>{{ bucket.bucketName }}</h4>
</div>
<div id="right">
<ul id='s3ItemDesc'>
<li>{{ bucket.createdAt }}</li>
<li>{{ bucket.totalsize }}/4GB</li>
<li>
<button type="button" name="button" class='button
delete'>Delete</button>
</li>
</ul>
</div>
</div>
{% endfor %}
{bucket%中的bucket为%1}
{{bucket.bucketName}
- {{bucket.createdAt}}
- {{bucket.totalsize}}/4GB
-
删除
{%endfor%}
谢谢你,安妮塔,工作很有魅力!我没有想到要编一本字典。
