Summary: I am creating a web page which shows the results of user selections. I have two files. html and jquery. I have created a variable reports_array = [ ] which collects all the selections of user when "Done" button is clicked.
问题:我必须将report_array []值传递给django视图.
Issue: I have to pass reports_array[ ] values to the django view.
这是jquery的代码
Here is the code for jquery
.on('click','.done', function(){
var report_array = [];
report_array.push(
{
Layer_Table: layer_array,
Benefits_Table: benefits_array,
Map_Layer_selection: save_selection_layer,
Map_Benefits_selection: save_selection_benefits,
});
console.log(report_array);
这是view.py的代码
Here is the code for view.py
def done(request):
template = loader.get_template('maps/done.html')
context = RequestContext(request, {
'reports_link': report_array, //I believe this is not correct.
})
return HttpResponse(template.render(context))
如何将jquery的report_array传递到此上下文" ... ????假设done.html包含以下代码
how to pass report_array from jquery to this "context"...???? assume done.html contains following code

我是django界面的新手.假设url.py是正确的.我正在寻找我在这里缺少的逻辑.
I am new to django interface. Assume url.py is correct. I am looking for logic that i am missing here.

我不确定我是否了解您要如何呈现报告数组.但是要将JQuery数组传递给Django视图，您可以使用AJAX调用Django URL
I am not sure I understood how you want to present the report array. But to pass JQuery array to Django view you can use AJAX call to Django URL
var obj = {'report_array': report_array}
$.ajax({
type: 'POST',
url: '/DESTINATION_URL/',
contentType: 'application/json; charset=utf-8', //EDITED
data: JSON.stringify(obj),
success: function(data) {
$('body').html(data); //EDITED
},
error: function(rs, e) {
alert(rs.responseText);
}
});
然后在您的views.py
Then in your views.py
import json
from django.template.loader import render_to_string
def done(request):
params = json.loads(request.body)
report_array = params['report_array']
html_data = render_to_string('maps/done.html', {'reports_link': report_array})
return HttpResponse(html_data)
然后您的done.html可以是这样的:
Then your done.html can just be this:
<body>
<p>{{ reports_link }}</p>
</body>
通过这种方式，AJAX将呈现您的页面以在成功时显示report_array.因此它将在不重新加载页面的情况下更改正文的内容.
This way AJAX will render your page to show the report_array on success. So it will change the content of body without reloading the page.
