Ember and Rails-Grape API - PUT/POST problem

1

Hi everyone :smile: Unfortunatelly I don’t know why my put and post requests not good for my server-side. I generate templates in ember through: ember g scaffold… I can delete/show items, but I can’t edit, create new projects. What’s wrong with this?

 module API
  module V1
    class Projects < Grape::API
      include API::V1::Defaults

      resource :projects do
        desc "Return all projects"
    get "", root: :projects do
      Project.all
    end

    desc "Return a project"
    params do
      requires :id, type: String, desc: "ID of the project"
    end
    get ":id", root: "project" do
      Project.where(id: permitted_params[:id]).first!
    end

    desc "Create a project."
    params 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
    post do
      Project.create!({
                          name: params[:name],
                          user_id: params[:user_id],
                          description: params[:description],
                          project_type_id: params[:project_type_id]
                      })
    end

    desc "Update a project."
    params 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
    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

    desc "Delete a project."
    params do
      requires :id, type: String, desc: "project ID."
    end
    delete ':id' do
      Project.find(params[:id]).destroy
    end

      end


    end
  end
end

@updater did you solve this issue? A have the same problem, and can’t figure out how to get grape to ignore the root object.

You have to nest the params in model object param then it works

example

desc 'Add new Opportunity with given params'
    params do
      requires :opportunity, type: Hash do
        requires :name, type: String, desc: 'Opportunity name'
      end
    end

    post do
      opportunity_params = params[:opportunity]

      Opportunity.create opportunity_params
    end

Alternatively you can override your adapter:

import DS from 'ember-data';

export default DS.ActiveModelAdapter.extend({
  // this method is almost copy-pasted from ActiveModelAdapter
  updateRecord: function(store, type, snapshot) {
    var data = {};
    var serializer = store.serializerFor(type.typeKey);

    serializer.serializeIntoHash(data, type, snapshot);

    var id = snapshot.id;
    var url = this.buildURL(type.typeKey, '', snapshot, 'updateRecord');

    return this.ajax(url + '/' + id, 'PUT', {
      // this line is changed!
      data: data[type.typeKey]
    });
  }
});
