Change Date format in Django model

对着背影说爱祢 提交于 2019-12-09 19:00:52
问题 I have a date field called "birthdate" and property called "lifespan" in a django model. Field birthdate = models.DateField(blank=True, null=True) Property @property def lifespan(self): return '%s - present' % self.birthdate Currently lifespan returns the date in the "yyyy-mm-dd" format. How can I changed this date format to "mm/dd/yyyy"? I know how to do it in a django template with a filter but wanted to see if there was a similar "filter" that I can use in a Django model. I appreciate the

问题 For some reason, setting the application locale to nl_NL does not affect my datefield components. Dates are still displayed in english language/formatting. I tried using the following: But this does not work. Am I doing something wrong? I guess I could make a custom datefield component, where I supply the dutch translations for those dates, including the formatting, but this is a way I rather not like to go... 回答1: you can use formatString to specify the dateFomat you wish to use. <mx

Can I create Date entry control with date separator for classic ASP

∥☆過路亽.° 提交于 2019-12-08 08:54:21
问题 I was using a calendar control for entry of date in a classic-ASP application. But calendar control is not keyboard friendly and take more time for data entry. So later I added a simple text box with date validation. It works fine. However, the user need to put the date separator also. I wish to put a date entry field that comes with a pre-configured date format and separator, so that the user simply type on the numbers and the field cause a validation as well. How can I achieve this? 回答1:

django forms dateField fails validation

坚强是说给别人听的谎言 提交于 2019-12-05 13:18:10
I am trying to validate a User Profiling form in django and I can't. It seems that there is something wrong with forms.dateField(). It does not validate (ie. is_valid() return false) this is my forms dateField entry: date_of_birth = forms.DateField(label=u'date of birth', input_formats='%d/%m/%Y', required=False, widget=forms.DateInput(format = '%d/%m/%Y')) I noticed that request.POST.get('date_of_birth', '') returns the correct date (ie. the date I have typed in the html form field). I also noticed that in this function: def clean_date_of_birth(self): date = self.cleaned_data['date_of_birth']

Django Monthly/quartarly grouping of DateField() data

笑着哭i 提交于 2019-12-04 13:06:47
I've got a django model which contains, among other things, a DateField() attribute: class Table(): date = models.DateField() value = models.FloatField() I'm writing a view that groups this data by week, month Quarter and year. I've hardcoded a calculation that gets my monthly value simply enough - by adding up all the values in that month and deviding by how many entries there were - but I feel like there must be a more elegant way of doing this. What I'm aiming for is something like this: get_monthly(Table.objects.all()) >>> [123, 412, 123, 534, 234, 423, 312, 412, 123, 534, 234, 423] get
