Django is Free and Open Source web application framework written in Python.

Which works on MVT(model view template) Framework .

 

Step 1: Create a model 

 

As it is MVT architecture we have to define a model.It inludes what are all field required in your api you have to declare here with proper class fields.

Here i have created a model class with fields with their type .

 

from django.db import models

 

class Company(models.Model):

    name = models.CharField("Coamapny's official Name",max_length=100)

    address = models.CharField(max_length=100)

    no_of_employee = models.IntegerField("Number of Employees",default=0)

    business = models.TextField()

 

Step 2: Create a view

 

This layer contains the logic that access the model and defers to the appropriate template which includes POST and GET request

 

Once you have declared data fields in model next step is create Form for posting data into database here i created ComapnyForm class with model delared  and crerated a POST request in views .which is passed to template with all the data entered in form as a dicttionary.

 

 

from django import forms

from models import Company

 

class CompanyForm(forms.ModelForm):

    class Meta:

        model = Company

 

from django.shortcuts import render_to_response

from django.http import HttpResponseRedirect

 

def create_company(request):

    if request.POST:

        form = CompanyForm(request.POST) 

        if form.is_valid():

              form.save()

              return HttpResponseRedirect('/articles/all')

    else:

           form = CompanyForm()

 

  args ={ }  

  args.update(csrf(request))

  args['form'] = form 

  return render_to_response('create_company.html',args)

 

Step 3 :Create a Template and Configure a URL

 

In the template we will display a form which will display in widget format to user  asking fields declared in Model .

Once you fill all the details and on click of Create Company it will save in database.by this way we can post N no of details to Database

 

 

Create a HTML File

 

 

{% csrf_token %}

{{ form.as_ul }}

 

 

 

 

 

 

 

Next step is build a URL through wich you can access your data.here you can declare a URL format which will call the views function

to get API details.

 

create an object of company resource and hook that to url config 

 

from django.conf.urls import patterns,include,url

from api import CompanyResource

 

comapny_resource = CompanyResource()

 

urlpatterns = patterns('',

url(r'^create_company/$','company.views.create_company'),

url(r'^api/',include(comapny_resource.urls)),

)

 

 

 

Which provides a rest style API

you can  create a new resource (POST)

Upadate the existing resources (PUT)

Deleting a Resources(DELETE)

 

Here we will import our model class with all posted class objects. and resouce name which we will display in api. it will build API format with data.

 

from tastypie.resources import ModelResource

from models import Company

 

class CompanyResource(ModelResource):

    class Meta:

        queryset = Company.objects.all()

        resource_name = 'company'

 

 

Final Step is run a localserver and open a formed API which include resource name and serilization type

 

http://127.0.0.1:8000/api/company/?format=json/

 

Which will give api resource in json format.
