我有一个非常复杂的情况。

from types import *
from django import forms
from django.db.models import Q
from django.core.exceptions import ValidationError
from schdeules.models import tbmsttemplate,tbmstreviewsched,tbtrnrevdepartments,tbtrnrevdesignations,tbmstappraisalsched,tbtrnappraisalreview,tbmstdepartment,tbmstpart,tbmstsection,tbtrnappraisalquestion
class tbmstappraisalschedForm(forms.ModelForm):
  def clean(self):
      """ 
      Override the default clean method to check whether this course has been already inputted.
      """    
      cleaned_data = super(tbmstappraisalschedForm, self).clean()

      depart_id = self.cleaned_data.get('intDeptID')
      fromdate = str(self.cleaned_data.get('sdtFromDate'))
      todate = str(self.cleaned_data.get('sdtToDate'))
      pk=self.instance.pk

      res = tbmstappraisalsched.objects.filter( 
      Q(sdtFromDate__lte=fromdate,sdtToDate__gte=fromdate) |  \
      Q(sdtFromDate__lte=todate,sdtToDate__gte=todate), ~Q(intAppSchedID=pk),
      intDeptID=depart_id.pk,
      )
      if(res).exists():
        raise ValidationError('The slot is present for selected dates and selected department')

      else:
        res_revs = tbmstreviewsched.objects.filter( 
        Q(sdtFromDate__lte=fromdate,sdtToDate__gte=fromdate) |  \
        Q(sdtFromDate__lte=todate,sdtToDate__gte=todate),     
        tbtrnrevdepartments__intDeptID=depart_id.pk,
        )
        if(res_revs).exists():
           show review scheds such that user can select needed review scheds and save data in two models at once i.e; tbmstappraisalsched,tbtrnappraisalreview
           return self.cleaned_data 
        else: 
            raise ValidationError('Reviewschedule slots are not present for the selected dates and selected department')


class Meta:
    model = tbmstappraisalsched

在上面的代码中，我必须从 tbmstreviewsched 获取审查计划并向用户显示，以便他可以选择所需的审查计划并一次将数据保存在两个模型中，这样数据必须保存在 tbmstappraisalsched 中，它返回 intappschedid(autoincrement value ) 然后数据必须保存在 tbtrnappraisalreview 中，并带有新的 intappschedid 和选定的审核 sched id。我的 admin.py 代码是

from schdeules.models import  tbmsttemplate,tbmstreviewsched,tbtrnrevdepartments,tbtrnrevdesignations,tbmstappraisalsched,tbtrnappraisalreview,tbmstpart,tbmstsection,tbtrnappraisalquestion
from django.core.exceptions import ValidationError
from forms import tbmstappraisalschedForm

class QuestionsInline(admin.StackedInline):
 model = tbtrnappraisalquestion
 extra = 0
class TemplatesAdmin(admin.ModelAdmin):

 readonly_fields = ("intUpdatedBy",)
 inlines = [QuestionsInline]

 def save_model(self, request, obj, form, change):
    obj.intUpdatedBy = request.user.id
    obj.save()
class ReviewDesignationInline(admin.StackedInline):
 model = tbtrnrevdesignations
 extra = 1
class ReviewDepartmentInline(admin.StackedInline):
 model = tbtrnrevdepartments
 exclude = ['intUpdatedBy']
 extra = 1
class ReviewScheduleAdmin(admin.ModelAdmin):
 inlines = [ReviewDepartmentInline,ReviewDesignationInline]
 exclude = ['intUpdatedBy']
 def save_model(self, request, obj, form, change):
    obj.intUpdatedBy = request.user.id
    obj.save()
class AppraisalScheduleAdmin(admin.ModelAdmin):
 exclude = ['intUpdatedBy']
 form = tbmstappraisalschedForm
 def save_model(self, request, obj, form, change):
    obj.intUpdatedBy = request.user.id
    obj.save()
class AppraisalReviewAdmin(admin.ModelAdmin):
 exclude = ['intUpdatedBy']
 def save_model(self, request, obj, form, change):
    obj.intUpdatedBy = request.user.id
    obj.save()

admin.site.register(tbmstpart)
admin.site.register(tbmstsection)
admin.site.register(tbmsttemplate,TemplatesAdmin)
admin.site.register(tbmstreviewsched,ReviewScheduleAdmin)
admin.site.register(tbmstappraisalsched,AppraisalScheduleAdmin)
admin.site.register(tbtrnappraisalreview,AppraisalReviewAdmin)
