在我的rails应用程序中,我有一个ajax请求到服务器,以存储一些数据.这曾经没有任何问题,但现在我收到一个错误:
ActionController::UnknownFormat (ActionController::UnknownFormat):
app/controllers/reservations_controller.rb:45:in `create'
以下是控制器和我的javascript文件,其中我声明数据类型是JSON
class ReservationController < ApplicationController
respond_to :html, :json
def create
...
respond_to do |format|
if @reservation.save
format.html do
redirect_to '/'
end
format.json { render json: @reservation.to_json }
else
render 'new'
end
end # respond_to
end # create
end # ReservationController
function.js
$.ajax({
url: url_link,
dataType: 'json',
type: 'POST',
data: dataToSend
})
完整的错误日志是:

# config/environments/test.rb
config.after_initialize do
Bullet.enable = true
Bullet.bullet_logger = true
Bullet.raise = true # raise an error if n+1 query occurs
end
# spec/spec_helper.rb
if Bullet.enable?
config.before(:each) do
Bullet.start_request
end
config.after(:each) do
Bullet.perform_out_of_channel_notifications if Bullet.notification?
Bullet.end_request
end
end
但是当我运行规范时,似乎在规范本身而不是应用程序中标记N + 1个查询.你知道是否有可能达到我的目的吗？

我刚刚在我的应用程序上安装了Devise,我之前已经像迈克尔哈特教程那样在头上完成了它.
目前我可以注册并注销.但是当我登录时会出错:
No route matches [POST] "/sessions/user"
当我点击登录/登录按钮时,无论是否有(正确的)密码,都会发生这种情况.
我的路线文件是:
SampleApp::Application.routes.draw do
devise_for :users, path_names: { sign_in: "login", sign_out: "logout"}
resources :users do
resources :bookings, only: [:show]
end
resources :bookings
resources :sessions

match '/admin', to: 'admin#new', via: :get
match "bookings/new", to: 'bookings#new', via: [:post, :get]

在我的应用程序中,我已经有上传图片的回形针,但需要更改以接受图像和视频.图像已经在具有belongs_to关系的模型中定义,称为Attachment.由于视频也将是相同父模型的附件(在我的案例中,文章),我想Attachment为图像和视频重用相同的模型.这是一个好主意吗？
我的代码 attachment.rb是:
class Attachment < ActiveRecord::Base
belongs_to :article
has_attached_file :url, :s3_protocol => :https ,
styles: {
medium: "300x300>", thumb: "100x100>", big: "1200x1200>", normal: "600x600>"
}
validates_attachment_content_type :url, content_type: /\Aimage|\Avideo\/.*\Z/
validates_attachment :url, content_type: { content_type: ["image/jpeg", "image/gif", "image/png", "video/mp4"] }
end
但事实并非如此,它并没有在S3上存储视频.我在终端上得到以下内容

我schema.rb有很多这样的评论消息：
# Could not dump table "geographic_data" because of following StandardError
# Unknown type 'geometry(MultiLineString,4326)' for column 'geom'
我的问题/怀疑：
如果我安装 ActiveRecord PostGIS 适配器，它会清除我在这些非模型表中已有的所有数据吗？这是一种可能的情况吗？
我正在做一个 Rails 应用程序，它主要是一个 API。我正在尝试测试我的 API 端点的控制器。我的 RSpec 控制器测试仪如下：
require 'rails_helper'
require 'spec_helper'
require 'rack/test'
require 'devise'
class RoutesControllerTest < ActionController::TestCase
describe "User with token"
test "should post route" do
params = { route: { start_lat: 38.7627951, start_long: -9.1532211,
end_lat: 38.7483783, end_long: -9.155045,
flag_opt: 0.4, city: 1 }
}
post '/routes.json' , params.to_json, format: :json
assert_response :success
end
end
end
我的控制器是：
class RoutesController < ApplicationController
def create
city = City.find(params[:route][:city])
user = current_user
@route = user.routes.new(route_params)
@results = @route.calc_route(@route.start_long, @route.start_lat, @route.end_long, …在我的 html 表单中，我有两种不同类型的输入，其$scope变量与模型相同。
我有 3 个单选按钮和一个数字输入字段
<div class="form-group">
<div class="btn-group" data-toggle="buttons">
<label class="btn btn-primary">
<input type="radio" ng-model="article.internal_memory" value="16" name="options" id="option1" > 16GB
</label>
<label class="btn btn-primary">
<input type="radio" ng-model="article.internal_memory" value="32" name="options" id="option2" > 32GB
</label>
<label class="btn btn-primary">
<input type="radio" ng-model="article.internal_memory" value="64" name="options" id="option3" > 64GB
</label>
</div>
<input ng-model="article.internal_memory" id="internal-memory-input" placeholder="Outra" type="number" class="form-control">
</div>
但是，如果我选择其中一个单选按钮输入，它不会设置该值。
同一个作用域变量有两个不同的输入会导致冲突吗？
