如何在 django 中序列化字典以在 Jquery 中呈现 [问题级别 - 初学者]

要序列化的字典 - 表单错误

例如查看 -

form = PersonalForm(request.POST)
# errors = serializing function which serializes form.errors
data = errors 
#Is this the way to pass data? Not quite sure....
return HttpResponse(data,mimetype="application/json")

例如 javascript（请求成功） -

function(responseData) {
     $('#errors_form').html(responseData);
                },

现在我该怎么做，我的朋友？

原文

The dictionary to serialize -
form.errors

e.g. view -

form = PersonalForm(request.POST)
# errors = serializing function which serializes form.errors
data = errors 
#Is this the way to pass data? Not quite sure....
return HttpResponse(data,mimetype="application/json")

e.g. javascript (on success of request) -

function(responseData) {
     $('#errors_form').html(responseData);
                },

Now how do I do this my friends?

import json

data = json.dumps(errors)

return HttpResponse(data,mimetype="application/json")

您询问如何将字典转换为 JSON 对象，以便您的 jQuery/javascript 可以读取它。 json.dumps 允许这种情况发生。

import json

data = json.dumps(errors)

return HttpResponse(data,mimetype="application/json")

You're asking how to turn a dictionary into a JSON object, so your jQuery/javascript can read it. json.dumps allows this to happen.

您需要在两个地方查找错误。

有“非字段错误”：

form.non_field_errors

以及基于字段的错误，例如名称字段：

form.name.errors

根据表单的复杂性，您可以将错误作为 json 中的单独错误引用，或者制作一个将它们组合在一起的小型 python 脚本。我实际上没有运行代码，但认为这对你有用：

errors = []
errors = errors + form.non_field_errors

for field in form:
    errors = errors + field.errors

if len(errors) > 0 :
    data = json.dumps({"response_text": "Errors Detected", "errors" : errors})

You will need to look in two places for errors.

There are "Non field errors":

form.non_field_errors

And field based errors, for example the name field:

form.name.errors

Depending on the complexity of the form, you could reference the errors as individual errors in your json, or make a small python script that combined them. I didn't actually run the code, but think this could work for you:

errors = []
errors = errors + form.non_field_errors

for field in form:
    errors = errors + field.errors

if len(errors) > 0 :
    data = json.dumps({"response_text": "Errors Detected", "errors" : errors})
