我已经尝试了很多,但无法解决它.在我的packages.json中添加react-native-easy-gridview之前,一切都运行良好,然后我检查了我的更改,之后我得到了这个.

这是我的build.gradle

    apply plugin: "com.android.application"
import com.android.build.OutputFile


apply from: "../../node_modules/react-native/react.gradle"


def enableSeparateBuildPerCPUArchitecture = false


def enableProguardInReleaseBuilds = false

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.1"

    defaultConfig {
        applicationId "com.pilbara_weed_management_mobile"
        minSdkVersion 16
        targetSdkVersion 22
        versionCode 8
        versionName "1.0"
        ndk {
            abiFilters "armeabi-v7a", "x86"
        }
    }
    signingConfigs {
            release {
                if (project.hasProperty('MYAPP_RELEASE_STORE_FILE')) {
                    storeFile file(MYAPP_RELEASE_STORE_FILE)
                    storePassword MYAPP_RELEASE_STORE_PASSWORD
                    keyAlias MYAPP_RELEASE_KEY_ALIAS
                    keyPassword MYAPP_RELEASE_KEY_PASSWORD
                }
            }
        }
    splits {
        abi {
            reset()
            enable enableSeparateBuildPerCPUArchitecture
            universalApk false  // If true, also generate a universal APK
            include "armeabi-v7a", …

我可以用这种方式更改路由中的:id参数的名称,但这可以更改嵌套资源的参数,就像我有

resources :companies, param: :company_id do
  resources :shares, only[:index]
end

这会产生像这样的路线

/companies/:company_company_id/shares

哪个错了我想要这样的路线

/companies/:company_id/shares

我需要做什么？

我已将我的rails项目的版本从4.2升级到5.2.1我的一些测试失败,因为完整跟踪上的pg连接关闭错误如下所示.

    Failure/Error: DatabaseCleaner[:active_record].clean_with(:truncation)

我是 react-native 的新手我正在向服务器发送请求并希望在同一块中获得响应和正文，以便我可以将这两个项目发送到另一个函数，我的 fetch 方法看起来像

send_request = (data) =>{
  url = BASE_URL + "some/url.json"
  fetch(url, {
    method: 'POST',
    headers: {
      'Accept': 'application/json',
      'Content-Type': 'application/json',
    },
    body: JSON.stringify({
      user: {
        email: data.email,
        full_name: data.name,
      }
    })
  }).then((response) => {
    //how can I get response body here so that I can call following method
    // this.use_response(responsebody, response.headers)
    return response.json()
  }).then((responseJson) => {
    // or how can I get response headers here so that I can call following fuction
    // this.use_response(responseJson, headers)
    return …

嗨,我正在使用seed_dump gem从现有数据创建seeds.rb,但我坚持一件事,我想为所有模型获取ID以及我如何才能做到这一点,例如我现在运行

rake db:seed:dump

我只是得到这样的代码

Product.create(title: "title", description: "text")

但我想要这个

Product.create(id: 1, title: "title", description: "text")

我怎样才能做到这一点？

我有一个非常奇怪的错误,我有一个设计用户模型

class User < ActiveRecord::Base
  # Include default devise modules. Others available are:
  # :lockable, :confirmable, :timeoutable,:omniauthable and
  devise :database_authenticatable, :registerable,
     :recoverable, :rememberable, :trackable, :validatable
end

在我的routes.rb我有这些路线

devise_for :users, :controllers => {confirmations: 'confirmations', :registrations => "registrations", :sessions=>"sessions"}

我的更新用户表单看起来像这样的东西

<%= form_for(resource, as: resource_name, url: registration_path(resource_name), html: { method: :put }) do |f| %>
            <% if flash[:error] %>
                <div class="alert alert-danger fade in" role="alert">
                  <%= flash[:error] %>
                </div>
            <% end %>
            <% if devise_error_messages? %>
                <div class="alert alert-danger fade in" role="alert">
                  <%= …

我正在使用国家和country_select宝石.宝石中缺少一些国家,或者某个国家/地区是否可以添加自定义数据并在我们的rails项目中使用新国家或州.我需要做什么？
