Rails with Grape API - 参数中的关系 id 作为过滤器
Rails with Grape API - relation id in params as a filter
在我的 Rails/Grape API 应用程序中,我有一个端点,我在其中列出了所有用户注释。模型 Note
与模型 Activity
有可选关系(注释可以是 activity 的一部分,如下所示)。
class Note < ApplicationRecord
belongs_to :user
belongs_to :activity, optional: true
end
我的端点如下所示:
module Notes
class Index < Base
desc 'All user notes',
success: { code: 200 },
failure: [
{ code: 401, message: 'The access token is invalid' },
{ code: 401, message: 'The access token expired' },
{ code: 404, message: "Couldn't find Notes" },
]
get do
::DetailedSerializer.new(
Note.where(user_id: current_user.id),
)
end
end
end
我想按活动过滤笔记(例如只显示 activities_id = 1
的笔记)。为此,我需要在参数中使用 activities_id
作为过滤器,但我不知道这种操作的语法是什么,如何实现?
在葡萄中获取参数的语法 API :-
desc 'Your description.'
params do
requires :id, type: Integer, desc: 'Model ID.'
end
get do
Model.find(params[:id])
end
所以根据你的代码:-
class Index < Base
desc 'All user notes',
success: { code: 200 },
failure: [
{ code: 401, message: 'The access token is invalid' },
{ code: 401, message: 'The access token expired' },
{ code: 404, message: "Couldn't find Notes" },
]
params do
optional :activity_id, type: Integer, desc: 'Activity filter.'
end
get do
## then you can use this id for filter in your query
puts "activity_id ====> #{params[:activity_id]} "
::DetailedSerializer.new(
Note.where(user_id: current_user.id),
)
end
end
您可以将此参数设置为 optional
或 requires
:-
params do
optional :activity_id, type: Integer, desc: 'Activity filter.'
end
或
params do
requires :activity_id, type: Integer, desc: 'Activity filter.'
