如何使用django项目上传csv文件
我正尝试在django中创建文件上传。
inventory.html：
我有两个按钮download_inventory按钮下载一个CSV文件。 我正尝试使用upload_inventory按钮上传文件。
<form method="POST" action="{% url 'bulkInventory' %}">
{% csrf_token %}
<div class="panel-body">
<div class="pad-btm form-inline">
<div class="row">
<div class="col-sm-6 table-toolbar-left">
<button name="download_inventory" id="download_inventory" class="btn btn-purple btn-labeled fa">Download Inventory</button>
<input type="file" class="btn btn-purple" name="inventory_csv" >
<button name="upload_inventory" id="upload_inventory" class="btn btn-purple btn-labeled fa dropzone" >Upload Inventory</button>
</div>
.....
urls.py：
方法bulkInventory与行动bulkInventory映射。
urlpatterns = patterns('',
url(r'^$', views.inventory, name='inventory'),
url(r'^product.html/', views.product, name='product'),
url(r'^update/', views.updateSingle, name='update'),
url(r'^inventory/', views.bulkInventory, name='bulkInventory'),)
views.py：
def bulkInventory(request):
api = APIMethods()
if request.method == 'POST' and 'download_inventory' in request.POST:
api.downloadInventory()
inv_file = open('inventory_sheet.csv', 'rb')
response = HttpResponse(inv_file, content_type='application/csv')
response['Content-Disposition'] = "attachment; filename=inventory_sheet.csv"
os.system('rm inventory_sheet.csv')
return response
if request.method == 'POST' and 'upload_inventory' in request.POST:
form = forms.UploadFile(request.POST, request.FILES)
print form.is_valid()
api.saveUploadedInventory(request.FILES['inventory_csv']) # this method saves the content of file
return HttpResponseRedirect(reverse('inventory'))
forms.py：
class UploadFile(forms.Form):
inventory_file = forms.FileField()
它给了我这个错误：
Traceback：在get_response 132中的文件“/home/manish/syserp/local/lib/python2.7/site-packages/django/core/handlers/base.py”。
响应= wrapped_callback（请求，* callback_args，** callback_kwargs）文件“/home/manish/syserp/ekomerz/inventory/views.py”in bulkInventory 78. api.saveUploadedInventory（request.FILES ['inventory_csv']）File“/ home / manish / syserp / local / lib / python2.7 / site-packages / django / utils / datastructures.py“中的值。raise MultiValueDictKeyError（repr（key））
异常类型：/ product / inventory /中的MultiValueDictKeyError异常值：“'inventory_csv'”
为什么form.cleaned_data[''inventory_csv] form.is_valid()之后去form.cleaned_data[''inventory_csv]
在此之前，检查你得到什么打印form.cleaned_data['inventory_csv']
希望有帮助
