1.景点详情接口开发

1.设计响应数据结构

文件地址：sight/serializers.py

创建类：

class SightDetailSerializers(BaseSerializer):
    #景点详情
    def to_dict(self):
        obj = self.obj
        return {
            'id': obj.id,
            'name': obj.name,
            'desc': obj.desc,
            'img': obj.banner_img.url,
            'content': obj.content,
            'score': obj.score,
            'min_price': obj.min_price,
            'province': obj.province,
            'city': obj.city,
            'area': obj.area,
            'town': obj.town,
            'comment_count': 0
        }

2.设计视图函数

向数据库中获取数据，文件地址：sight/views.py。

class SightDetailView(DetailView):
    #景点详情信息
    def get_queryset(self):
        # 获取数据
        return Sight.objects.all()

    def render_to_response(self, context, **response_kwargs):
        #响应数据
        page_obj = context['object']
        if page_obj is not None:
            if page_obj.is_valid ==False:
                return NotFoundJsonResponse()
            date = serializers.SightDetailSerializers(page_obj).to_dict()
            return http.JsonResponse(date)
        return NotFoundJsonResponse()

3.构建地址的函数

文件地址：sight/urls.py

访问成功可执行sight/views.py

配置具体函数地址，参数1：自定义访问地址，参数2：访问函数的位置，参数3：连接名

urlpatterns = [
    path('sight/detail/<int:pk>',
         views.SightDetailView.as_view(),
         name='sight_detail'),
]

2.景点评论接口开发

1.设计返回图片格式

创建文件system/serializers.py

序列化基础图片，其他列表需要关联图片时，引用该类

from utils.serializers import BaseSerializer
class BaseImageSerializer(BaseSerializer):
    def to_dict(self):
        image = self.obj
        return {
            'img': image.img.url,
            'summary': image.summary,
        }

2.评论列表序列化

文件地址：sight/serializers.py

class CommentListSerializers(BaseListPageSerializer):
    #评论列表
    def get_object(self, obj):
        user = obj.user
        images = []
        for image in obj.images.filter(is_valid = True):
            images.append({
                'img': image.img.url,
                'summary': image.summary
            })
        return {
            'user': {
                'pk': user.pk,
                'nickname': user.nickname
            },
            'pk': obj.pk,
            'content': obj.content,
            'is_top': obj.is_top,
            'love_count': obj.love_count,
            'score': obj.score,
            'is_public': obj.is_public,
            'images': images,
            'created_at': obj.created_at.strftime('%Y-%m-%d %H:%M:%S'),
        }

3.设计视图函数

文件地址：sight/views.py

class SightCommentListView(ListView):
    #景点评论列表
    paginate_by = 10

    def get_queryset(self):
        #根据id查询景点信息
        sight_id = self.kwargs.get('pk', None)
        sight = Sight.objects.filter(pk = sight_id,is_valid = True).first()
        if sight:
            return sight.comments.filter(is_valid = True)
        return Comment.objects.none()

    def render_to_response(self, context, **response_kwargs):
        page_obj = context['page_obj']
        if page_obj is not None:
            data = serializers.CommentListSerializers(page_obj).to_dict()
            return http.JsonResponse(data)
        return NotFoundJsonResponse

4.构建地址函数

 文件地址：sight/urls.py

path('comment/list/<int:pk>',
     views.SightCommentListView.as_view(),
     name='sight_comment_list')

3.景点信息及门票接口开发

1.设计响应数据结构

创建门票和景点列表的类

class TicketListSerializers(BaseListPageSerializer):
    #门票列表
    def get_object(self, obj):
        return {
            'pk': obj.pk,
            'name': obj.name,
            'desc': obj.desc,
            'types': obj.types,
            'price': obj.price,
            'discount': obj.discount,
            'total_stock': obj.total_stock,
            'remain_stock': obj.remain_stock
        }
class SightInfoSerializer(BaseSerializer):
    #景点列表
    def to_dict(self):
        obj = self.obj
        return {
            'pk': obj.sight.pk,
            'entry_explain': obj.entry_explain,
            'play_way': obj.play_way,
            'tips': obj.tips,
            'traffic': obj.traffic
        }

2.设计视图函数

class SightTicketListView(ListView):
    #景点门票列表视图
    paginate_by = 10
    def get_queryset(self):
        #根据景点id查询
        sight_id = self.kwargs.get('pk', None)
        return Ticket.objects.filter(sight_id = sight_id,is_valid = True)

    def render_to_response(self, context, **response_kwargs):
        page_obj = context['page_obj']#获取对象
        if page_obj is not None:
            data = serializers.TicketListSerializers(page_obj).to_dict()
            return http.JsonResponse(data)
        return NotFoundJsonResponse()

class SightInfoDetail(DetailView):
    #当地址pk为None时，以下配置会生效
    pk_url_kwarg = None
    #URL中参数的名称
    slug_url_kwarg = 'pk'
    #URL中pk对应的哪一个字段（数据库中的字段）
    slug_field = 'sight__pk'
    #景点详情列表视图
    def get_queryset(self):
        return Info.objects.all()

    def render_to_response(self, context, **response_kwargs):
        page_obj = context['object']
        if page_obj is not None:
            data = serializers.SightInfoSerializer(page_obj).to_dict()
            return http.JsonResponse(data)
        return NotFoundJsonResponse()

3.构建地址函数

urlpatterns = [
    path('ticket/list/<int:pk>/',
         views.SightTicketListView.as_view(),
         name='sight_ticket_list'),
    path('sight/info/<int:pk>/',
         views.SightInfoDetailView.as_view(),
         name='sight_info')
]

4.网页检测网址

http://localhost:8000/sight/sight/detail/1/

http://localhost:8000/sight/comment/list/1/

http://localhost:8000/sight/ticket/list/1/

http://localhost:8000/sight/sight/info/1/
