Django SelectDateWidget只顯示月份和年份

Question

是否有不同的窗口小部件或參數，將允許Django只顯示/採取年和月輸入，而不是年，月和日？

當前使用SelectDateWidget。

Answer 1

這裏有一個片段here，它將當天設置爲1（假設你有一個DateField這個值將最終結束，你需要得到某種日子）。

的代碼是這樣的（以防萬一Django的片段消失）：

import datetime 
import re 

from django.forms.widgets import Widget, Select 
from django.utils.dates import MONTHS 
from django.utils.safestring import mark_safe 

__all__ = ('MonthYearWidget',) 

RE_DATE = re.compile(r'(\d{4})-(\d\d?)-(\d\d?)$') 

class MonthYearWidget(Widget): 
    """ 
    A Widget that splits date input into two <select> boxes for month and year, 
    with 'day' defaulting to the first of the month. 

    Based on SelectDateWidget, in 

    django/trunk/django/forms/extras/widgets.py 


    """ 
    none_value = (0, '---') 
    month_field = '%s_month' 
    year_field = '%s_year' 

    def __init__(self, attrs=None, years=None, required=True): 
     # years is an optional list/tuple of years to use in the "year" select box. 
     self.attrs = attrs or {} 
     self.required = required 
     if years: 
      self.years = years 
     else: 
      this_year = datetime.date.today().year 
      self.years = range(this_year, this_year+10) 

    def render(self, name, value, attrs=None): 
     try: 
      year_val, month_val = value.year, value.month 
     except AttributeError: 
      year_val = month_val = None 
      if isinstance(value, basestring): 
       match = RE_DATE.match(value) 
       if match: 
        year_val, month_val, day_val = [int(v) for v in match.groups()] 

     output = [] 

     if 'id' in self.attrs: 
      id_ = self.attrs['id'] 
     else:

一個Python 3插件這裏https://djangosnippets.org/snippets/10522/樣品。

用法示例：

class myForm(forms.Form): 
    # ... 
    date = forms.DateField(
     required=False, 
     widget=MonthYearWidget(years=xrange(2004,2010)) 
    )

我碰到同樣的問題，今天來和通過CSS屬性去除白天場和設置1作爲對清理當天的值來解決它。

#id_my_date_field_day-button { 
    display: none; 
} 

我用的ModelForm與更新視圖，因此在我的領域這讓生活簡單一點，因爲我一向對my_date_field當天有效值有初始數據。
