需要在django模板中将字符串转换为int [英] Need to convert a string to int in a django template

问题描述

我正在尝试将url参数传递给这样的django模板...

I am trying to pass in url parameters to a django template like this...

response = render_to_string('persistConTemplate.html', request.GET)

这是来自我的views.py文件的调用行。 persistConTemplate.html是我的模板和请求的名称.GET是包含url参数的字典。

This the calling line from my views.py file. persistConTemplate.html is the name of my template and request.GET is the dictionary that contains the url parameters.

在模板中，我尝试使用这样的参数之一...

In the template I try to use one of the parameters like this...

{% for item in (numItems) %}

  item {{item}}

{% endfor %}

numItems是url参数之一我按照我的请求发送...

numItems is one of the url parameters that I am sending in my request like this...

http:/someDomain/persistentConTest.html/?numItems=12

当我尝试上面的for循环时，我得到一个这样的输出....

When I try the for loop above, I get an output like this....

image 1 image 2

image 1 image 2

我期待着喜欢看单词图像打印12次...

I am expecting and would like to see the word image printed 12 times...

图像1图像2图像3图像4图像5图像6图像7图像8图像9图像10图像11图像12

image 1 image 2 image 3 image 4 image 5 image 6 image 7 image 8 image 9 image 10 image 11 image 12

任何人都可以告诉我我出了什么问题？

Can anyone please tell me what I am going wrong?

推荐答案

是的，这个地方在视图中。

Yes, the place for this is in the view.

我觉得上面的例子不会工作 - 你不能迭代一个整数。

I feel like the above example won't work -- you can't iterate over an integer.

numItems = request.GET.get('numItems')

if numItems:
   numItems = range(1, int(numItems)+1)

return direct_to_template(request, "mytemplate.html", {'numItems': numItems})


{% for item in numItems %}
 {{ item }}
{% endfor %}
