Django DateTimeField输入表单

Question

我在我的模型中有一个DateTime字段，我正在寻找一种简单的方法来使它在表单中看起来很好。比如SelectDateWidget。

我一直在看很多类似的问题，它似乎真的很棘手的东西，如管理日期picker或jquery的工作。(这是我第一次使用Django，我从来没有使用过jquery)。

所以，我从这个例子中使用ChoiceField代替，但我也不能让它工作。我得到错误名称'self'未定义。这里可以不用self吗?或者是否有更好的简单的方法来做到这一点?我不需要一个花哨的日期选择器，只需要一些让用户容易输入的东西。

class ProjectForm(ModelForm):
    startdate = forms.DateField()
    starthour = forms.ChoiceField(choices=((6,"6am"),(7,"7am"),(8,"8am"),(9,"9am"), ...))
    startminute = forms.ChoiceField(choices=((0,":00"),(15,":15"),(30,":30"),(45,":45")))
    class Meta:
        model = Project
    def clean(self):
        starttime = time(int(self.cleaned_data.get('starthour')), 
                         int(self.cleaned_data.get('startminute')))
        return self.cleaned_data
    try:
        self.instance.start_time = datetime.datetime.combine(
            self.cleaned_data.get("startdate"), starttime)
    except TypeError:
        raise forms.ValidationError("")

forms.py

from django import forms
from django.contrib.admin import widgets                                       
class MyForm(forms.ModelForm):
    class Meta:
        model = MyModel
    def __init__(self, *args, **kwargs):
        super(MyForm, self).__init__(*args, **kwargs)
        self.fields['mydate'].widget = widgets.AdminDateWidget()
        self.fields['mytime'].widget = widgets.AdminTimeWidget()
        self.fields['mydatetime'].widget = widgets.AdminSplitDateTime()

在模板:

<script type="text/javascript" src="/my_admin/jsi18n/"></script>
<script type="text/javascript" src="/media/admin/js/core.js"></script>

…或者，对于Django 1.4+:

{% load static %}
<link rel="stylesheet" type="text/css" 
    href="{% static 'admin/css/forms.css' %} "/>
<link rel="stylesheet" type="text/css" 
    href="{% static 'admin/css/base.css' %} "/>
<link rel="stylesheet" type="text/css" 
    href="{% static 'admin/css/global.css' %}"/>
<link rel="stylesheet" type="text/css" 
    href="{% static 'admin/css/widgets.css' %}"/>
<script type="text/javascript" 
    src="/admin/jsi18n/"></script>
<script type="text/javascript" 
    src="{% static 'admin/js/core.js' %}"></script>
<script type="text/javascript" 
    src="{% static 'admin/js/admin/RelatedObjectLookups.js' %}"></script>
<script type="text/javascript" 
    src="{% static 'admin/js/jquery.js' %}"></script>
<script type="text/javascript" 
    src="{% static 'admin/js/jquery.init.js' %}"></script>
<script type="text/javascript" 
    src="{% static 'admin/js/actions.js' %}"></script>
<script type="text/javascript" 
    src="{% static 'admin/js/calendar.js' %}"></script>
<script type="text/javascript" 
    src="{% static 'admin/js/admin/DateTimeShortcuts.js' %}"></script>

Answer 2

如果你被错误所困扰

Could not parse the remainder: '/js/jquery.init.js'' from 'admin/js/jquery.init.js''". 

只需在admin/js/jquery.init.js之前添加一个撇号它看起来像:

'admin/js/jquery.init.js'
