Question

我想创建类似于django admin changelist view with list_editable items ...

我成功创建了视图。但是，当我发布它死于验证错误。

 if request.POST:
        formset_class = modelformset_factory(Job)
        formset =formset_class(request.POST, request.FILES)
        if formset.is_valid():
           formset.save()

问题是我只有几个属性可编辑。因此，其中一些不是POST的一部分，模型抱怨它们是强制性的。

但我想UPDATE对象不创建它们。基本上我真的想要管理员在设置list_editable但我自己的观点

时做的事情

Answer 1

我想要一个像管理员一样使用list_editable的功能，所以我去了它并且几乎复制了来自django源的options.py的代码。我为我的对象检索了admin，然后保存了原始值（函数fix_old_job_admin将它们设置回来）

此代码解决了我的问题

job_admin = admin.site._registry[Job]
# save old values so that you can go back to them later
old_list_display = job_admin.list_display
old_list_filter = job_admin.list_filter
old_ordering = job_admin.model._meta.ordering
job_admin.list_editable = ("time", "what", "approved")
cl = ChangeList(request, job_admin.model, job_admin.list_display, job_admin.list_display_links, job_admin.list_filter, job_admin.date_hierarchy, job_admin.search_fields, job_admin.list_select_related, job_admin.list_per_page, job_admin.list_editable,job_admin.admin_site, job_admin)
# options.py from django framework lines 1181-1208 (v. 1.4) 
if request.POST:
    FormSet = job_admin.get_changelist_formset(request)
    formset =FormSet(request.POST, request.FILES, queryset=cl.result_list)
    if formset.is_valid():
        changecount = 0
        for form in formset.forms:
            if form.has_changed():
                obj = job_admin.save_form(request, form, change=True)
                job_admin.save_model(request, obj, form, change=True)
                job_admin.save_related(request, form, formsets=[], change=True)
                change_msg = job_admin.construct_change_message(request, form, None)
                job_admin.log_change(request, obj, change_msg)
                changecount += 1 

        if changecount:
            if changecount == 1:
                name = force_unicode(job_admin.model._meta.verbose_name)
            else:
                name = force_unicode(job_admin.model._meta.verbose_name_plural)
            msg = ungettext("%(count)s %(name)s was changed successfully.",
                                "%(count)s %(name)s were changed successfully.",
                                changecount) % {'count': changecount,
                                                'name': name,
                                                'obj': force_unicode(obj)}
            job_admin.message_user(request, msg)
        # call function that sets admin with original values
        fix_old_job_admin(job_admin, old_list_display, old_ordering, old_list_filter)
        return HttpResponseRedirect(request.get_full_path())


FormSet = job_admin.get_changelist_formset(request)
cl.formset = FormSet(queryset=cl.result_list)

context = Context({
    'app_label': ContentType.objects.get_for_model(Lawyer).app_label,
    'verbose_name_plural': Job._meta.verbose_name_plural.title(),
    "cl": cl,
    'request': request,

                   })
# call function that sets admin with original values
fix_old_job_admin(job_admin, old_list_display, old_ordering, old_list_filter)
return render_to_response('yourtemplate/similar_to_changelist.html', context, RequestContext(request))
