Question

我创建了完美的Grape-create动作

desc "Create a project."
        params do
          group :project, type: Hash do
            requires :name, type: String, desc: "Name of project."
            requires :user_id, type: String, desc: "user id"
            requires :description, type: String, desc: "Description of project"
            requires :project_type_id, type: String, desc: "Type of project"
          end
        end
        post do
          Project.create!(
              name: params[:project][:name],
              user_id: params[:project][:user_id],
              description: params[:project][:description],
              project_type_id: params[:project][:project_type_id]
          )
        end

但是，当我想创建一个PUT动作来编辑某些值时，我在JSON中的响应中出错：error: "project[id] is missing" 我的PUT代码：

desc "Update a project."
        params do
          group :project, type: Hash do
            requires :id, type: String, desc: "project ID."
            requires :name, type: String, desc: "Name of project."
            requires :user_id, type: String, desc: "user id"
            requires :description, type: String, desc: "Description of project"
            requires :project_type_id, type: String, desc: "Type of project"
          end
        end
        put ':id' do
          Project.find(params[:project][:id]).update!(
              name: params[:project][:name],
              user_id: params[:project][:user_id],
              description: params[:project][:description],
              project_type_id: params[:project][:project_type_id]
          )
        end

我做错了什么？

行。我通过此代码修复它并且它可以正常工作

desc "Update a project."
        params do
          group :project, type: Hash do
            requires :name, type: String, desc: "Name of project."
            requires :user_id, type: String, desc: "user id"
            requires :description, type: String, desc: "Description of project"
            requires :project_type_id, type: String, desc: "Type of project"
          end
        end
        put ':id' do
          Project.find(params[:id]).update!(
              name: params[:project][:name],
              user_id: params[:project][:user_id],
              description: params[:project][:description],
              project_type_id: params[:project][:project_type_id]
          )
        end

我不确定你的结构没有看到你在PUT请求中发送的内容，但我认为Grape代码应该是这样的 - 但同样，我完全猜测没有看到你的JSON有效载荷。

put ':id' do
  Project.find(params[:id]).update!(
    name: params[:name],
    user_id: params[:user_id],
    description: params[:description],
    project_type_id: params[:project_type_id]
  )
end
