我正在开发python2.7/django1.7上的产品应用程序。在
我有一个产品模型,即“产品配置文件”,我想让我的客户(最终用户)用表格询问有关特定产品的任何事情。在
但是,我无法从用户选择的产品中选择一个非常不合理的键。我还分配了url变量中的外键。在
这是我的代码:
class ProductProfile(models.Model):
category = models.ForeignKey(Category)
brand = models.ForeignKey(Brand)
product_name = models.CharField(max_length=128)
model_name = models.CharField(max_length=128)
generation = models.CharField(max_length=128)
processor = models.CharField(max_length=128)
ram = models.DecimalField(max_digits=2, decimal_places=0)
hdd = models.DecimalField(max_digits=6, decimal_places=2)
optical_drive = models.CharField(max_length=128)
display = models.CharField(max_length=128)
card_reader = models.CharField(max_length=128)
blue_tooth = models.CharField(max_length=128)
web_cam = models.CharField(max_length=128)
warranty = models.CharField(max_length=128)
price = models.DecimalField(max_digits=9, decimal_places=2)
condition = models.TextField()
product_image = models.ImageField(upload_to=update_Product_image_filename)
post_date = models.DateTimeField(db_index=True, auto_now_add=True)
# Override th __unicode__() method to return out something meaningful!
def __unicode__(self):
return self.product_name
class Customer_ps_contact(models.Model):
name = models.CharField(max_length=128)
email = models.EmailField(max_length=75)
subject = models.CharField(max_length=128 )
product = models.ForeignKey(ProductProfile)
message = models.TextField()
phone_regex = RegexValidator(regex=r'^\+?1?\d{9,15}$', message="Phone number must be entered in the format:
'+999999999'. Up to 15 digits allowed.")
phone_number = models.CharField(validators=[phone_regex], blank=True, max_length=15) # validators should be a
list
def __unicode__(self):
return self.name
def product_inquiry(request, product_id):
product = ProductProfile.objects.get(pk=product_id)
if request.method == 'POST':
#form = Customer_ps_contactForm(request.POST, initial = {'product': product})
#form = Customer_ps_contactForm(initial = {'product': product.id})
form = Customer_ps_contactForm(request.POST)
if form.is_valid():
form_data_dict = form.cleaned_data
print form_data_dict['product']
mail_customer_enquriy(form_data_dict) # Function to send email to admin
thank_u_customer(form_data_dict) # Function to send email to customers
form = form.save(commit=False)
form.product = product
form.save()
return home(request)
else:
print ("form is not valid")
print (form.errors)
else:
form = Customer_ps_contactForm()
context_dict = {'form':form, 'product': product}
return render(request, 'product/product_inquiry2.html',context_dict)
urlpatterns = patterns('',
url(r'^inquiry/(?P<product_id>\d+)/$', views.product_inquiry, name='price'), # Only relevent url given
)
{% extends 'base.html' %}
{% load crispy_forms_tags %}
{% block body_block %}
{% block title %}Product Inquiry{% endblock %}
<div class="row">
<div class="col-md-10 col-md-offset-1">
<h2 style="font-weight:bold">Enquiry regarding '{{product.product_name}}'</h2>
<hr>
<form id="contact_form" method="post" action=""/>
{% csrf_token %}
{{ form | crispy }}
<input class="btn btn-primary pull-right " type="submit" name="submit" value="Submit the Message" />
</form>
</div>
</div>
{% endblock %}
我该怎么办?在
您可以从url中的id知道产品是什么,所以不需要在表单中包含它。在
要检查数据库中是否存在该产品,可以使用
get_object_or_404
快捷方式。在然后从字段列表中去掉“product”,并删除带有隐藏输入小部件的
^{pr2}$ModelChoiceField
。在在保存产品时,您已经在设置产品,但是使用变量名},那么您就不必对
instance
可以更清楚地显示正在发生的事情。如果您更改mail_customer_enquriy
和thank_u_customer
方法来使用实例而不是{form.cleaned_data
做任何操作。在相关问题 更多 >
