问题 I have a Foreign Key from one model into another model in a differente database (I know I shouldn't do it but if I take care properly of Referential Integrity it shouldn't be a problem). The thing is that everything works fine...all the system does (relationships on any direction, the router takes care of it) but when I try to delete the referenced model (which doesn't have the foreign key attribute)...Django still wants to go throught the relationship to check if the relationship is empty,

问题 I followed the instructions here (https://github.com/talpor/django-dashing) a few times, but I never seem to be able to get the dashboard. All I get is the screenshot attached. Any help would be appreciated 回答1: Figured it out. This was due to using django 1.9. When I downgraded back to 1.8 problem was solved. 来源： https://stackoverflow.com/questions/34301130/cannot-get-django-dashing-example-to-work

问题 I have a custom django widget to replace the standard ModelChoiceField widget. class SelectModelWidget(forms.TextInput): """ @Usage: field = ModelChoiceField(queryset=Model.objects.all(), widget=SelectModelWidget(attrs={})) """ def __init__(self, attrs=None, title=None, template="widgets/select_widget.html"): super(SelectModelWidget, self).__init__(attrs) self.template = template self.title = title def render(self, name, value, attrs=None): if value is None: value = '' # TODO: the queryset

问题 After reading a bunch of blogs about this i can not find the answer, also searched in SO as well. I have a template that use django template tags: <div class="box" id="dates"> <h2 class="h2">Dates</h2> <ul class="list-group"> {% for days in dates %} <li class="list-group-item list-group-item-success">{{ days }}</li> {% endfor %} </ul> </div> This div waits for an answer that comes from an ajax response. Here is the ajax code: $("#formi").submit(function(event){ event.preventDefault(); var

问题 I'm using Django and would like to match the URLs domain.com/w and domain.com/words . I have a configuration line of the form: url(r'^w(ords)?$', 'app_name.views.view_words') view_words takes only one parameter ( request ), but it seems that Django captures the (ords) part of the regular expression and passes it to the view. When I remove (ords) from the regex and access domain.com/w , it works properly. The Django documentation and similar StackOverflow questions cover how to capture

问题 I've got a form with profile_picture=ImageField field set to the initial value. It's using ClearableFileInput widget. I need to customize the form in the template, so I can't simply use {{ form.profile_picture}} .
