Limit Django's inlineformset_factory to only create new objects

由 Deadly 提交于 2019-12-20 10:44:21
问题 I am using django's inline formset factory. To use the example in the docs, author = Author.objects.get(pk=1) BookFormSet = inlineformset_factory(Author, Book) formset = BookFormSet(request.POST, instance=author) will create an inline formset to edit books by a particular author.

Free-form input for ForeignKey Field on a Django ModelForm

由 孤人 提交于 2019-12-20 09:59:41

Editing Django _form.as_p

由 不想你离开。 提交于 2019-12-20 09:53:10
问题 By default _form.as._p spits out: <p><label for="id_subject">Subject:</label> <input id="id_subject" type="text" name="subject" maxlength="100" /></p> Whereas I need <p><label for="id_subject">Subject:</label><p> <input id="id_subject" type="text" name="subject" maxlength="100" /></p> with a break between the label and the input. How can I modify my Django code to do so? 回答1: You simply just can't use form.as_p anymore. If the defaults don't work for you, then you must render the fields

Django - UpdateView with inline formsets trying to save duplicate records?

由 吃可爱长大的小学妹 提交于 2019-12-20 09:38:03
问题 I have an Expense model and an ExpenseLineItem model. Just like a typical expense/invoice, one expense can have several line items to make up the total cost of an invoice.

Django TextField max_length validation for ModelForm

由 风格不统一 提交于 2019-12-20 09:29:20
问题 Django does not respect the max_length attribute of TextField model field while validating a ModelForm. So I define a LimitedTextField inherited from the models.TextField and added validation bits similar to models.CharField: from django.core import validators class LimitedTextField(models.TextField): def __init__(self, *args, **kwargs): super(LimitedTextField, self).__init__(*args, **kwargs) self.max_length = kwargs.get('max_length') if self.max_length: self.validators.append(validators
