问题 I have a model, Director with two DateFields, and two subclasses (code below). I am trying to create an admin page for each Director which shows the corresponding subclass instance, and not the Director instance; this part is mostly easy (I create an inline for each subclass, give the main ModelAdmin a form with all fields excluded, and have the main ModelAdmin only request formsets from the inlines which have a corresponding instance - the code; there is an unresolved issue with this

问题 I have a form with several fields. I have separate validation checks for each field, done via the forms validation. I however also need to check if few fields are filled in before redirecting the user to a different view. I was hoping I could somehow append the error to forms.non_field_errors as it is not for a particular field , but I am not sure what the right syntax for this would be. I have checked online and found.. form.errors['__all__'] = form.error_class(["error msg"]) This displays

I would like to better click on, say, name to go to the edit page. 回答1: You could have a look at django.contrib.admin.ModelAdmin

问题 I have a problem and I am using 2 libraries : django-autocomplete-light and django-dynamic-formset . The 2 are very good at doing their job.

Image of the problem when a new field is created, it is added in that way. Template: {% extends 'base/base.html' %} {% load static %} {% block titulo%} Registrar venta {%endblock%} {% block contenido %} <div class=

问题 I'm am utilizing a formset to enable users subscribe to multiple feeds. I require a) Users chose a subscription by selecting a boolean field, and are also required to tag the subscription and b) a user must subscribe to an specified number of subscriptions.

问题 I'm looking at creating an anonymous poll. However, I want to prevent users from voting twice. I was thinking of hashing some request.META values like so: from hashlib import md5 request_id_keys = ( 'HTTP_ACCEPT_CHARSET', 'HTTP_ACCEPT', 'HTTP_ACCEPT_ENCODING', 'HTTP_ACCEPT_LANGUAGE', 'HTTP_CONNECTION', 'HTTP_USER_AGENT', 'REMOTE_ADDR', ) request_id = md5('|'.join([request.META.get(k, '') for k in requst_id_keys])).hexdigest() My questions: Good idea? Bad idea? Why? Are some of these keys
