获取日期小部件以为美国用户显示美国日期 [英] Getting Date Widget to Display American Dates for American Users
问题描述
我可以使用此代码来检测用户是否在美国
I can use this code to detect if the user is in America
ip, is_routable = get_client_ip(request)
ip2 = requests.get('http://ip.42.pl/raw').text
if ip == "127.0.0.1":
ip = ip2
Country = DbIpCity.get(ip, api_key='free').country
widgets.py
如果用户是美国人，我想将信息传递给模板 bootstrap_datetimepicker.html.
If the user is American I want to pass information to the template bootstrap_datetimepicker.html.
我真的不确定如何在下面的代码(我从另一个网站获得)中添加有关用户所在国家/地区的信息.
I am really unsure how to add information about the users country to the below code (which I got from another website).
class BootstrapDateTimePickerInput(DateTimeInput):
template_name = 'widgets/bootstrap_datetimepicker.html'
def get_context(self, name, value, attrs):
datetimepicker_id = 'datetimepicker_{name}'.format(name=name)
if attrs is None:
attrs = dict()
attrs['data-target'] = '#{id}'.format(id=datetimepicker_id)
# attrs['data-target'] = '#{id}'.format(id=datetimepicker_id)
attrs['class'] = 'form-control datetimepicker-input'
context = super().get_context(name, value, attrs)
context['widget']['datetimepicker_id'] = datetimepicker_id
return context
bootstrap_datetimepicker.html
我想为美国用户运行一个不同的JQuery函数.
I want to run a different JQuery function for American users.
{% if America %}
<script>
$(function () {
$("#{{ widget.datetimepicker_id }}").datetimepicker({
// format: 'DD/MM/YYYY/YYYY HH:mm:ss',
format: 'MM/DD/YYYY',
changeYear: true,
changeMonth: false,
minDate: new Date("01/01/2015 00:00:00"),
});
});
</script>
{% else %}
<script>
$(function () {
$("#{{ widget.datetimepicker_id }}").datetimepicker({
// format: 'DD/MM/YYYY/YYYY HH:mm:ss',
format: 'DD/MM/YYYY',
changeYear: true,
changeMonth: false,
minDate: new Date("01/01/2015 00:00:00"),
});
});
</script>
{% endif %}
推荐答案
您可以使用Python软件包geoip2来确定用户的位置(单击这两个链接以获取有关安装geoip2的说明，
You can use Python package geoip2 to determine the location of the user (click on these two links for instructions on installing geoip2, get-visitor-location & maxminds).
from django.contrib.gis.geoip import GeoIP2
该请求也可以提取IP地址.
Also IP address can be extracted by the request.
ip = request.META.get("REMOTE_ADDR")
我在Localhost上运行我的网站时，遇到了上述问题.因此，我做了一个临时解决方案-
I was runnning my site on Localhost and had an issue with the above. So as a temporarily solution I did -
ip="72.229.28.185"
这是我在网上找到的随机美国IP地址.
This was a random American IP address I found online.
g = GeoIP2()
g.country(ip)
执行 print(g)将为您提供类似的信息
Doing print(g) will give you something like this
{'country_code': 'US', 'country_name': 'United States'}
在小部件构造函数中，确定位置.然后将国家/地区代码存储为上下文变量，如下所示:
In your widget constructor, determine the location. Then store the country code as a context variable, like so:
from django.contrib.gis.geoip import GeoIP2
class BootstrapDateTimePickerInput(DateTimeInput):
template_name = 'widgets/bootstrap_datetimepicker.html'
def __init__(self, *args, **kwargs):
self.request = kwargs.pop('request', None)
super().__init__()
def get_location(self):
ip = self.request.META.get("REMOTE_ADDR")
g = GeoIP2()
g.country(ip)
return g
def get_context(self, name, value, attrs):
datetimepicker_id = 'datetimepicker_{name}'.format(name=name)
if attrs is None:
attrs = dict()
attrs['data-target'] = '#{id}'.format(id=datetimepicker_id)
# attrs['data-target'] = '#{id}'.format(id=datetimepicker_id)
attrs['class'] = 'form-control datetimepicker-input'
context = super().get_context(name, value, attrs)
context['widget']['datetimepicker_id'] = datetimepicker_id
location = self.get_location()
context['widget']['location'] = location['country_code']
return context当我遵循Lewis的代码时，我遇到了一个错误.您可以在此处阅读更多有关该错误的信息.
When I was following Lewis' code I had an error. You can read more about the error here.
TypeError: 'NoneType' object is not subscriptable
我对Lewis的代码进行了以下更改.
I made the below changes to Lewis' code.
def get_location(self):
ip = self.request.META.get("REMOTE_ADDR") (or ip="72.229.28.185")
g = GeoIP2()
location = g.city(ip)
location_country = location["country_code"]
g = location_country
return g
location = self.get_location()
context['widget']['location'] = location
然后在表单中定义窗口小部件的位置，确保将 request 传递给窗口小部件，以允许您在窗口小部件类中使用它，从而确定位置.将< field_name> 替换为表单字段的名称.
Then where you define the widget in the form, ensure you pass request into the widget to allow you to utilise it in the widget class thus determining location. Replace <field_name> with the name of the form field.
class YourForm(forms.Form):
[...]
def __init__(self, *args, **kwargs):
request = kwargs.pop('request', None)
super().__init__(*args, **kwargs)
self.fields[<field_name>].widget = BootstrapDateTimePickerInput(request=request)
在您看来，您还必须将请求传递到给定的表单中:
Also in your view you must pass request into the given form:
form = YourForm(request=request)
最后在窗口小部件中使用如下条件:
Finally in the widget just use condition like so:
<script>
$(function () {
$("#{{ widget.datetimepicker_id }}").datetimepicker({
// format: 'DD/MM/YYYY/YYYY HH:mm:ss',
format: {% if widget.location == 'US' %}'MM/DD/YYYY'{% else %}'DD/MM/YYYY'{% endif %},
changeYear: true,
changeMonth: false,
minDate: new Date("01/01/2015 00:00:00"),
});
});
</script>
其他问题
我需要找到一种告诉后端日期格式是mm/dd/yyyy还是dd/mm/yyyy的方法.
I need to find a way of telling the back end if the date format is mm/dd/yyyy or dd/mm/yyyy.
def __init__(self, *args, **kwargs):
request = kwargs.pop('request', None)
super().__init__(*args, **kwargs)
self.fields['d_o_b'].widget = BootstrapDateTimePickerInput(request=request)
(a) self.fields['d_o_b'].input_formats = ("%d/%m/%Y",)+(self.input_formats)
(b) self.fields['d_o_b'].widget = BootstrapDateTimePickerInput(request=request, input_formats=['%d/%m/%Y'])
