python - 将表单数据保存到DB并将其发送到API； Django的

我是Django的新手，正在尝试捕获用户信息。提交表单后，数据将保存到数据库。我还想将邮政编码字段发送到sunlight Foundation的API，以便在提交表单后为用户提供有用的信息。

当阳光脚本位于HOME.HTML中时，它将返回基于邮政编码的列表，但Django不会保存数据。从HOME.HTML删除脚本后，数据将保存到数据库中。我怎么能两全其美，数据由Django保存，并且列表在用户提交表单后呈现。我应该将阳光脚本放置在其他位置吗（views.py？）？

感谢您抽出宝贵的时间对此进行检查，并可能会对您有所帮助！

格式

from django import forms
from .models import SignUp

class SignUpForm(forms.ModelForm):
    class Meta:
        model = SignUp
        fields = ['name_last', 'name_first', 'email', 'zipcode',]

#overriding/adding to django validation
    def clean_email(self):
        email = self.cleaned_data.get('email')
        return email

    def clean_name_first(self):
        name_first = self.cleaned_data.get('first_name')
        #write validation code.
        return name_first

    def clean_zipcode(self):
        zipcode = self.cleaned_data.get('zipcode')
        return zipcode

模型

from django.db import models

class SignUp(models.Model):
    email = models.EmailField(max_length=120)
    name_first = models.CharField(max_length=120, blank=True, null=True) #optional and also: default=''
    name_last = models.CharField(max_length=120,)
    zipcode = models.CharField(max_length=120,)

    def __unicode__(self):
        return self.email

观点

from django.shortcuts import render

from .forms import SignUpForm

def home(request):
    title = 'Welcome'
    form = SignUpForm(request.POST or None)

    context = {
        "title": title,
        "form": form,
    }

    if form.is_valid():
        instance = form.save(commit=False)

        first_name = form.cleaned_data.get("first_name")
        if not first_name:
            first_name = "None Given"
            instance.first_name = first_name
        instance.save()
        context = {
        "title": "Thanks",
        }

    return render(request, "home.html", context)

最佳答案

从视图内部调用阳光的API怎么样。可以按以下步骤完成：

    def home(request):
        if request.method=="POST":
            payload = {'apikey' : apiKey,
                    'zip' : request.POST.get('zipcode'),}
            response = requests.get("http://congress.api.sunlightfoundation.com/legislators/locate?callback=?",params=payload)

现在，根据需要使用此响应。像在模板中一样处理响应，然后将处理后的数据传递回上下文。

您无需通过js访问API。在您的模板中，提交表单。
