Django 1.7从内联形式移除添加按钮 [英] Django 1.7 removing Add button from inline form
问题描述
我有完全可修改的模型(Prodotto,Comune),显示为可添加字段,如下图所示。
我不希望看到的是这个字段的+(添加)按钮,因此可以删除这个表单中的可添加适当性。
我已经尝试在两个模型中设置 has_add_permission = False ,但是它不会将这个模型完全添加到新的对象中,而不仅仅是这种形式。
我该怎么做?
编辑:为了澄清我的需要,我不想在FK模型的字段旁边有+,但是我仍然希望能够添加全新的内联。为了尽可能清楚,正如我在评论中写的,考虑一个这样的场景: https://code.djangoproject.com/attachment/ticket/20367/django_custom_user_admin_form.png 我只需要删除组和国家旁边的+。

此应用程序的管理界面产生:
快捷链接1和2是我需要删除的,被引用到我的内联类中的列(FKs) 。
快捷链接3和4将被保留,因为它们自己引用内嵌。
我认为这是一个比你最后的一个更简洁的解决方案。无论如何,它为我工作。
基本上,它是与您建议使用的重写ModelAdmin的 get_form 方法的内联等价物。这里我们覆盖内联类中的 get_formset ,从窗体集中获取表单,并执行完全相同的操作。似乎工作正常,至少在1.9,我正在使用。
class VersionEntryInline(admin.TabularInline):
template ='admin / edit_inline / tabular_versionentry.html'
model = VersionEntry
extra = 0
def get_formset(self,request,obj = None,** kwargs)
覆盖formset函数,以便删除内联旁边的外键下拉
菜单旁边的添加和更改按钮
formset = super(VersionEntryInline,self).get_formset(request,obj,** kwargs)
form = formset.form
widget = form.base_fields ['project']。widget
widget .can_add_related = False
widget.can_change_related = False

I'm having problems achieving a (probably) rather simple task. I have fully modifiable models (Prodotto, Comune) which are shown as "addable" fields, as shown in picture below. What I'd rather not see is the + (add) button for such fields, hence to remove their "addable" propriety in this form. I've tried setting has_add_permission=False within the two models, but it would make it impossibile to add new objects to such models completely, not only in this form.
How can I do that?
EDIT: To clarify my need, I'd like NOT to have the "+"s next to the fields of the FK models, but I do still want to be able to add whole new inlines. To be as clear as possible, as I wrote in a comment, considering a scenario such as this: https://code.djangoproject.com/attachment/ticket/20367/django_custom_user_admin_form.png I just need to have the "+"s next to Groups and Country removed.

The admin interface of this app produces this:
Shortcut links 1 and 2 are the ones I need removed, being referred to columns (FKs) inside my inline classes. Shortcut links 3 and 4 are to be kept, since they refers to the inlines themselves.
I think this is a less hacky solution than the one you ended up with. It worked for me, anyway.
Basically, it's the inline equivalent of what you suggested doing with the overriding the get_form method of ModelAdmin. Here we override get_formset in the inline class, get the form off the formset, and do the exact same thing. Seems to work fine, at least in 1.9, which I am using.
class VersionEntryInline(admin.TabularInline):
template = 'admin/edit_inline/tabular_versionentry.html'
model = VersionEntry
extra = 0
def get_formset(self, request, obj=None, **kwargs):
"""
Override the formset function in order to remove the add and change buttons beside the foreign key pull-down
menus in the inline.
"""
formset = super(VersionEntryInline, self).get_formset(request, obj, **kwargs)
form = formset.form
widget = form.base_fields['project'].widget
widget.can_add_related = False
widget.can_change_related = False
widget = form.base_fields['version'].widget
widget.can_add_related = False
widget.can_change_related = False
return formset
