I am writing an rest API app based on Django rest-framework. I want to return my model data in JSON form
My models are :
from os import path
from django.db import models
from django.contrib import admin
from django.core.files.storage import FileSystemStorage
#------------------------------------------------------------------------------
projectDirPath = path.dirname(path.dirname(__file__))
storeImageDir = FileSystemStorage(location=projectDirPath + '/couponRestApiApp/stores')
class tags(models.Model):
""" This is the tag model """
tag = models.CharField(max_length=15) # Tag name
tagDescription = models.TextField() # Tag Description
tagSlug = models.CharField(max_length=400) # Extra info can be added to the existing tag using this field
createdAt = models.DateTimeField(auto_now_add=True) # Time at which tag is created
updatedAt = models.DateTimeField(auto_now=True) # Time at which tag is updated
def __unicode__(self):
"""Method to display string correctly"""
return unicode(self.tag)
class Meta:
"""Meta class to control display Behavior of the Model name """
verbose_name_plural = "Tags"
class stores(models.Model):
""" This is the store model """
storeName = models.CharField(max_length=15) # Store Name
storeDescription = models.TextField() # Store Description
storeURL = models.URLField() # Store URL
storePopularityNumber = models.IntegerField(max_length=1) # Store Popularity Number
storeImage = models.ImageField(upload_to="images") # Store Image
storeSlug = models.CharField(max_length=400) # This is the text you see in the URL
createdAt = models.DateTimeField(auto_now_add=True) # Time at which store is created
updatedAt = models.DateTimeField(auto_now=True) # Time at which store is updated
storeTags = models.ManyToManyField(tags) # All the tags associated with the store
def __unicode__(self):
"""Method to display string correctly"""
return unicode(self.storeName)
def StoreTags(self):
return '\n'.join([s.tag for s in self.storeTags.all()])
def StoreImage(self):
return '<img src="/media/couponRestApiApp/stores/%s" height="150"/>' % (self.storeImage)
StoreImage.allow_tags = True
class Meta:
"""Meta class to control display Behavior of the Model name """
verbose_name_plural = "Stores"
class coupons(models.Model):
""" This is the coupon model """
couponValue = models.CharField(max_length=4) # Coupon value in RS.
couponDescription = models.TextField() # Coupon Description
couponURL = models.URLField() # Coupon click URL
couponStore = models.ForeignKey(stores) # Key of coupon to store
tagName = models.ForeignKey(tags,on_delete=models.PROTECT) # Tag names associated to coupon
success = models.TextField() # Count of the number of times people have made it work
failures = models.TextField() # Count of the number of times this has failed
lastTested = models.DateTimeField(auto_now=True) # When was the coupon last tested
createdAt = models.DateTimeField(auto_now_add=True)
updatedAt = models.DateTimeField(auto_now=True)
class Meta:
"""Meta class to control display Behavior of the Model name """
verbose_name_plural = "Coupons"
class app(models.Model):
""" This is the application model which is using the API """
appName = models.CharField(max_length=20) # Application name
appDomain = models.CharField(max_length=20) # Application description
appKey = models.TextField() # Application Key
createdAt = models.DateTimeField(auto_now_add=True) # Time at which Application is added is created
updatedAt = models.DateTimeField(auto_now=True) # Time at which Application details are updated
class Meta:
"""Meta class to control display Behavior of the Model name """
verbose_name_plural = "Apps"
class subscriptions(models.Model):
""" These are the emails that are subscribing """
app = models.CharField(max_length=20) # The application where the email came from
store = models.CharField(max_length=20) # The optional store on which the email wants an update
tag = models.CharField(max_length=20) # The optional tag on which the email wants an update
emailID = models.EmailField() # EmailID of the registered user
active = models.BooleanField(default=True) # They may have unsubscribed
createdAt = models.DateTimeField(auto_now_add=True) # Time at user subscribed to the alerts
updatedAt = models.DateTimeField(auto_now=True) # Time at which user updated its subscription
class Meta:
"""Meta class to control display Behavior of the Model name """
verbose_name_plural = "Subscriptions"
class tagsAdmin(admin.ModelAdmin):
list_display = ('tag', 'tagDescription', 'tagSlug')
class storesAdmin(admin.ModelAdmin):
list_display = ('storeName','storeDescription','storeURL',
'storePopularityNumber','StoreImage',
'storeSlug','createdAt','createdAt','StoreTags'
)
class couponsAdmin(admin.ModelAdmin):
list_display = ('couponValue','couponDescription','couponValue',
'couponURL', 'couponStore','tagName','success',
'failures','createdAt','updatedAt'
)
class appsAdmin(admin.ModelAdmin):
list_display = ('appName','appDomain','appKey',
'createdAt','updatedAt'
)
class subcriptionsAdmin(admin.ModelAdmin):
list_display = ('app','store','tag','emailID',
'active','createdAt','updatedAt'
)
admin.site.register(tags,tagsAdmin)
admin.site.register(stores,storesAdmin)
admin.site.register(coupons,couponsAdmin)
admin.site.register(app,appsAdmin)
admin.site.register(subscriptions,subcriptionsAdmin)
#------------------------------------------------------------------------------
I have written a class in my views.py as:
from rest_framework import status
from rest_framework.views import View
from rest_framework.response import Response
from couponRestApiApp.models import app,coupons,stores,subscriptions,tags
------------------------------------------------------------------------------
class getAllStores(View):
"""
Provides access to all orders within the system.
"""
def get(self, request):
"""
Return a list of all orders.
"""
storeResponse = [i.storeName for i in stores.objects.all()]
print storeResponse
return (storeResponse)
And my URL.py is :
from django.contrib import admin
from couponRestApiApp.views import getAllStores
from django.conf.urls import patterns, include, url
#------------------------------------------------------------------------------
admin.autodiscover()
urlpatterns = patterns('',
url(r'^admin/', include(admin.site.urls)),
url(r'^media/(?P<path>.*)$', 'django.views.static.serve',
{'document_root': "/home/vaibhav/TRAC/coupon-rest-api/couponRestApi/", 'show_indexes': False}),
url(r'^stores/$',getAllStores.as_view(), name='getAllStores'),
)
But if i make request(http://localhost:8000/stores/) the following error is thrown:'list' object has no attribute 'status_code'
Please tell me how to serialize the model data using rest-framework into JSON objects....
