Python金字塔-使用会话将表单数据传递到另一个页面。
Python金字塔-使用会话将表单数据传递到另一个页面。
提问于 2017-11-13 01:37:37
我使用Python金字塔和Jinja2模板。我希望将表单数据保存到会话中，并在另一个HTML页面中检索它。为了传递数据，我应该如何更改？我只知道如何像这样将Views.py中的I键存储到会话中，但这不是request.session['postal'] = 01934中的数据。如果我使用print (session['postal'])，这只会显示在命令提示符中，而不会显示HTML页面。有人能帮我吗？我是个新手。
在我的Views.py中添加/更改什么？
我的HTML: Delivery.jinja2
<form class="form-horizontal" method="POST">
<div class="form-group">
<label class="control-label col-md-2" for="postal">Postal Code:</label>
<input type="text" class="form-control" id="postal" placeholder="Enter Postal Code" name="postal" />
</div>
<div class="form-group">
<label class="control-label col-md-2" for="address">Detailed Address:</label>
<textarea class="form-control" rows="3" id="address" placeholder="Enter Address" name="address"></textarea>
</div>
<div class="form-group">
<label class="control-label col-md-2" for="unit">Unit No #:</label>
<input type="text" class="form-control" id="unit" placeholder="Enter Unit No" name="unit" />
</div>
<button type="submit" class="btn btn-default" name="submit">Submit</button>
</form>Views.py
@view_config(route_name='deliveryLink', renderer='templates/deliveryLink.jinja2')
def deliveryLink(request):
print("YAY for gift delivery via Link")
if 'submit_deliverylink' in request.POST:
print("request.POST: ", request.POST)
myform = request.POST
for m in myform:
print("key: ", m, " value: ", myform[m])
session = request.session
session['postal'] = ?
session['address'] = ?
session['unit'] = ?
data = "??"
data_array = data.split(",")
session['data'] = data_array
session['delivery'] = str(data_array)
print (session['delivery'])
return HTTPFound(location='http://localhost:5555/confirmation')
return {}
@view_config(route_name='confirmation', renderer='templates/confirmation.jinja2')
def confirmation(request):
print("YAY for confirmation")
for a in request.POST:
request.session[a] = request.POST[a]
return {}我希望以前输入的数据显示在这个确认页面上: Confirmation.jinja2
<form class="form-horizontal" method="POST">
<div class="form-group">
<label class="control-label col-md-2" for="postal">Postal Code:</label>
<input type="text" class="form-control" id="postal" name="postal" />
</div>
<div class="form-group">
<label class="control-label col-md-2" for="address">Detailed Address:</label>
<textarea class="form-control" rows="3" id="address" name="address"></textarea>
</div>
<div class="form-group">
<label class="control-label col-md-2" for="unit">Unit No #:</label>
<input type="text" class="form-control" id="unit" name="unit" />
</div>
</form>回答 1

我认为，您可以将帖子从初始表单传递到确认页面的模板，而不需要会话。
如果您需要会话，可以从模板调用它。
<input type="text" class="form-control" id="postal" name="postal" value="{{session['postal']}}" />
# after form submitted, it sends post request, just check if it exist
if request.POST:
print("request.POST: ", request.POST)
myform = request.POST
# you need iterate over keys for this case
for m in myform.keys():
print("key: ", m, " value: ", myform[m])
session = request.session
# you can access request.POST directly or use your variable myfrom
# use myform.get('postal','') to get value by key
session['postal'] = myform.get('postal','')
session['address'] = myform.get('postal','')
session['unit'] = myform.get('unit','')
data = "??"
data_array = data.split(",")
session['data'] = data_array
session['delivery'] = str(data_array)
print (session['delivery'])
