Question

我是django的初学者。我尝试在一个页面上实现多个表单。我成功地打印了表格，我有一个问题。我只填写对应于button4的表单，即crawl_attri，然后单击button4，它在其他字段上显示需要以下字段的错误。我应该做什么改变，以便它只显示与我点击的按钮相对应的错误....

views.py
from django.shortcuts import render,render_to_response, RequestContext
from django.http import HttpResponseRedirect
from .forms import *
from selenium import webdriver
import MySQLdb


def my_view(request):
    form = first_form(request.POST or None)
    preset_form = websiteform(request.POST or None)
    crawl_attri=crawl_attribute(request.POST or None)
    crawl_css=crawl_url_attribute_css_sel(request.POST or None)
    prod=prodid(request.POST or None)
    if request.method=="POST":
      if preset_form.is_valid() and 'button2' in request.POST:
        save_it=preset_form.save(commit=False)
        save_it.save()
        return HttpResponseRedirect('')

      elif 'button1' in request.POST and prod.is_valid():
        save_it=prod.save(commit=False)
        save_it.save()
        return HttpResponseRedirect('')

      elif form.is_valid() and 'button3' in request.POST:
         save_it=form.save(commit=False)
         save_it.save()
         return HttpResponseRedirect('')         

      elif crawl_attri.is_valid() and 'button4' in request.POST:
        save_it=crawl_attri.save(commit=False)
        save_it.save()
        return HttpResponseRedirect('')

      elif crawl_css.is_valid() and 'button5' in request.POST:
        save_it=crawl_css.save(commit=False)
        save_it.save()    
        return HttpResponseRedirect('')


    return render_to_response('signup.html',{'preset_form': preset_form,'form':form,
            'crawl_attri':crawl_attri,'crawl_css':crawl_css,'prod':prod},RequestContext(request))

您应该在if块中实例化表单。例如，如果button1存在，则只将request.POST传递给preset_form。
