Django Crispy表單將無法保存/提交

Question

我無法使“提交”與crisp-froms一起使用。 帶有引導程序的普通django形式可以正常工作。 我已經嘗試了所有可以找到的教程，但目前無法找到代碼的問題。

單擊sumbit時，它將打開我的客戶概述頁面，但未添加任何新客戶。 此處未顯示所有字段，但所有字段設置均設置為允許空值。

我的models.py

from django.db import models
from django.utils.encoding import smart_unicode

class CustomerType(models.Model):
    customer_type = models.CharField(max_length=120, null=True, blank=True)
    timestamp_created = models.DateTimeField(auto_now_add=True, auto_now=False)
    timestamp_updated = models.DateTimeField(auto_now_add=False, auto_now=True)

    def __unicode__(self):
        return smart_unicode(self.customer_type)

class Customer(models.Model):
    customer_type = models.ForeignKey(CustomerType, null=True, blank=True)
    customer_name = models.CharField(max_length=120, null=True, blank=True)

我的views.py

def customercrispy(request): 
    form = ExampleForm()
    return render_to_response("customer-crispy.html",
                              {"example_form": form},
                              context_instance=RequestContext(request))

我的forms.py

from django import forms
from crispy_forms.helper import FormHelper
from crispy_forms.layout import Layout, Fieldset, ButtonHolder, Submit, Div, Field
from crispy_forms.bootstrap import TabHolder, Tab, FormActions
from .models import Customer

class CustomerAddForm(forms.ModelForm):
    class Meta:
        model = Customer

class ExampleForm(forms.ModelForm):
    def __init__(self, *args, **kwargs):
        super(ExampleForm, self).__init__(*args, **kwargs)
        self.helper = FormHelper(self)
        self.helper.form_method = 'post'
        self.helper.form_action = '/customeroverview/'     
        self.helper.add_input(Submit('submit', 'Submit'))

    class Meta:
        model = Customer

編輯：打開表單時，CMD輸出

[08/Oct/2014 12:45:12] "GET /customercrispy/ HTTP/1.1" 200 11203
[08/Oct/2014 12:45:12] "GET /customercrispy/static/js/ie-emulation-modes-warning.js HTTP/1.1" 404 3118
[08/Oct/2014 12:45:12] "GET /assets/js/ie10-viewport-bug-workaround.js HTTP/1.1" 404 3079

保存時的CMD輸出

[08/Oct/2014 12:46:52] "POST /customeroverview/ HTTP/1.1" 200 5129
[08/Oct/2014 12:46:52] "GET /customeroverview/static/js/ie-emulation-modes-warning.js HTTP/1.1" 404 3124
[08/Oct/2014 12:46:52] "GET /assets/js/ie10-viewport-bug-workaround.js HTTP/1.1" 404 3079

您的看法不正確。 目前，您僅創建並渲染表單。 發布表單后，什么也沒做，只是再次呈現。 因此，如果是POST，請檢查該表單是否有效並保存。 這樣就可以使它類似於：

def customercrispy(request):
    if request.method == 'POST': 
        form = ExampleForm(request.POST)
        if form.is_valid():
            form.save()
            return redirect('customercripsy') # name of view stated in urls
    else:
        form = ExampleForm()

    return render_to_response("customer-crispy.html",
                          {"example_form": form},
                          context_instance=RequestContext(request))

這也避免了將“ / customeroverview /”設置為表單操作。 如果您確實要發布到此URL，則將customeroverview視圖添加到您的問題中。 順便說一句，我建議您使用Django的reverse功能創建您的網址。 （ https://docs.djangoproject.com/en/dev/ref/urlresolvers/#reverse ）。
