Question

这是我第一次尝试实现'文件上传功能'，我需要你的帮助。我正在研究遗留数据库，我应该在以这种方式创建的表中进行文件上传：

CREATE TABLE  "LICENCE" 
(   "ID" NUMBER NOT NULL ENABLE, 
"VEH_ID" NUMBER NOT NULL ENABLE, 
"DTP_ID" NUMBER NOT NULL ENABLE, 
"LICENCENO" VARCHAR2(50 CHAR) NOT NULL ENABLE, 
"ISSUEDATE" DATE, 
"STARTDATE" DATE, 
"EXPIREDATE" DATE, 
"DOCPATH" VARCHAR2(500 CHAR), 
"CHECKFLAG" NUMBER(1,0) NOT NULL ENABLE, 
 CONSTRAINT "LIC_PK" PRIMARY KEY ("ID") ENABLE, 
 CONSTRAINT "LIC_DTP_FK" FOREIGN KEY ("DTP_ID")
  REFERENCES  "DOCTYPES" ("ID") ENABLE, 
 CONSTRAINT "LIC_VEH_FK" FOREIGN KEY ("VEH_ID")
  REFERENCES  "VEHICLES" ("ID") ENABLE)/

使用inspectdb，我得到了这个模型：

class Licence(models.Model):
    id = models.DecimalField(unique=True, primary_key=True, max_digits=127, decimal_places=0)
    veh_id = models.ForeignKey(Vehicles, db_column='veh_id')
    dtp_id = models.ForeignKey(Doctypes, db_column='dtp_id')
    licenceno = models.CharField(max_length=200)
    issuedate = models.DateField(null=True, blank=True)
    startdate = models.DateField(null=True, blank=True)
    expiredate = models.DateField(max_length=2000, blank=True)
    docpath = models.CharField(max_length=200)
    checkflag = models.IntegerField()

    def __unicode__(self):
        return self.licenceno

我应该如何处理上传？阅读django文件上传文档后我的想法是将docpath修改为filefield。这是正确的做法吗？因为我尝试了它并且表单没有通过验证，而我得到“没有选择文件”。有人可以指导我吗？

我的views.py是：

def upload(request):

    if "doc-form" in request.POST:
        form = LicenceForm(data=request.POST, files=request.FILES)

        if form.is_valid():
            form.save()
            return render_to_response('bingo.html', locals(), context_instance=RequestContext(request)
    else:
        form = LicenceForm()

    return render_to_response('upload.html', locals(), context_instance=RequestContext(request))

以及我模板中的表单：

<form enctype="multipart/form-data" id="insertDocsForm" method="post" action='/upload/'>{% csrf_token %}
   <div class="id">
   {{ form.id.errors }}
    <label for="id"></label>
   {{ form.id }}
  </div>
  <div class="veh_id">
   {{ form.veh_id.errors }}
    <label for="veh_id">veh:</label>
  {{ form.veh_id }}
  </div>
  <div class="dtp_id">
   {{ form.dtp_id.errors }}
    <label for="dtp_id">dpt:</label>
   {{ form.dtp_id }}
  </div>
  <div class="licenceno">
   {{ form.licenceno.errors }}
    <label for="licenceno">lic:</label>
   {{ form.licenceno }}
  </div>
  <div class="issuedate">
   {{ form.issuedate.errors }}
    <label for="issuedate">isdate:</label>
   {{ form.issuedate }}
  </div>
  <div class="startdate">
   {{ form.startdate.errors }}
    <label for="startdate">stdate</label>
   {{ form.startdate }}
  </div>
    <div class="expiredate" >
   {{ docform.expiredate.errors }}
    <label for="expiredate">exdate:</label>
   {{ form.expiredate }}
  </div>
  <div class="docpath">
   {{ form.docpath.errors }}
    <label for="docpath"></label>
   {{ form.docpath }}
  </div>
  <div class="checkflag">
   {{ form.checkflag.errors }}
    <label for="checkflag"></label>
   {{ form.checkflag }}
  </div>
  <p>{{ form.errors }}

     {{ form.docpath.errors }}
  </p>
  <input type="hidden" name="doc-type" value="doc-form"
  <input type="submit" id="id_docSubmit"  value="Upload">
 </form>

Answer 1

您需要在模型中包含FileField字段，该字段将存储并充当文件。你的模型似乎没有。

HTML表单另一个警告是enctype="multipart/form-data"喜欢：

<form enctype="multipart/form-data" method="post" action="/foo/">

modelform不会使用文件上载进行验证
