我的网站遇到了一个问题,至少几周来我一直在努力解决这个问题,所以我希望有人能够指出我哪里出了问题。对于一些背景知识,我是一名应届毕业生,这是我为最终项目构建的顶点项目,在演示之前我没有完全获得我想要的所有功能,现在我已经完成了我正在尝试的课程介绍一下我觉得缺少的功能。话虽这么说,我用 Rails 后端和带有 Bootstrap 主题的 Vue 前端构建了一个恐怖电影愿望清单,我可以将它添加到观看列表中,并且可以将它们添加到喜爱的列表中或者讨厌它的列表,但我最不想要的事情是,当您单击按钮将其添加到所述列表时,它会将其从未观看的列表中删除。我在后端设置了一个布尔值,但对于我的生活,我无法得到正确的逻辑来让它从 true 翻转到 false 我不知道我是否需要前端的东西或什么,但就像我说的我我们已经尝试解决这个问题至少两周了,所以任何帮助都会很棒。

我的架构

create_table "hatedits", force: :cascade do |t|
    t.integer "movie_id"
    t.integer "user_id"
    t.string "box_art"
    t.datetime "created_at", precision: 6, null: false
    t.datetime "updated_at", precision: 6, null: false
  end

  create_table "lists", force: :cascade do |t|
    t.integer "user_id"
    t.integer "movie_id"
    t.boolean "watched"
    t.datetime "created_at", precision: 6, null: false
    t.datetime "updated_at", precision: 6, null: false
  end

  create_table "lovedits", force: :cascade do |t|
    t.integer "movie_id"
    t.datetime "created_at", precision: 6, null: false
    t.datetime "updated_at", precision: 6, null: false
    t.integer "user_id"
    t.string "box_art"
   end

  create_table "movies", force: :cascade do |t|
    t.string "name"
    t.string "description"
    t.string "box_art"
    t.string "sub_genre"
    t.datetime "created_at", precision: 6, null: false
    t.datetime "updated_at", precision: 6, null: false
    t.integer "year"
    t.string "category"
  end

  create_table "users", force: :cascade do |t|
    t.string "name"
    t.string "email"
    t.string "password_digest"
    t.datetime "created_at", precision: 6, null: false
    t.datetime "updated_at", precision: 6, null: false
  end

end

我的 Rails 更新和创建函数(我认为这就是问题所在,但我只是看不到它。)

def create
    list = List.create(
      user_id: current_user.id,
      movie_id: params[:movie_id],
      watched: false,
    )

    if list.save
      render json: list
    else
      render json: {errors: list.errors.full_messages}, status: 406
    end
  end 


  def update
    list = List.find_by(id: params[:id])
    list.movie_id = params[:movie_id] || list.movie_id
    if watched = true
      render json: list
    end 
 
 

    if list.save
      render json: list
    else
      render json: {errors: list.errors.full_messages}, status: 406
    end 
  end

我的前端带有移动到不同列表的按钮和方法,这些按钮和方法可以工作,但当电影移动到喜欢或讨厌的列表时,不会将电影从未观看的列表中删除,

<template>
  <div class="list">
    <br />
    <br />
    <br />
    <br />
    <br />
    <section id="portfolio" class="portfolio">
      <div class="container">
         <div class="row portfolio-container">
          <div class="col-lg-4 col-md-6 portfolio-item filter-app" v-for="list in lists" 
v-bind:key="list.id">
            <div class="portfolio-wrap">
              <img :src="`${list.movie.box_art}`" />
               <br />

              <div class="portfolio-info">
                <div class="portfolio-links">
                  <button v-on:click="lovedIt(list)">Loved It</button>

                  <br />
                  <br />
                  <button v-on:click="hatedIt(list)">Hated It</button>
                </div>
              </div>
            </div>
          </div>
        </div>
      </div>
    </section>
  </div>
</template>

<style>
.list {
  text-align: center;
  color: white;
}
img {
  height: 624px;
  width: 370px;
}
</style>
<script>
import axios from "axios";

export default {
  data: function () {
    return {
      list: {},
      lists: {},
      movie: [],
      currentUser: localStorage.getItem("user_id"),
    };
  },
  created: function () {
    this.indexLists();
  },
  methods: {
    indexLists: function () {
      axios.get("/lists").then((response) => {
        this.lists = response.data;
        console.log("list", response.data);
      });
    },
    addMovie: function () {
      axios.post("/lists", this.movie).then(() => {
        this.$router.push("/lists");
      });
    },
    lovedIt: function (list) {
      this.list = list;
      axios
        .post("/lovedits", {
          user_id: this.currentUser.id,
          movie_id: this.list.movie_id,
        })
        .then(() => {
          console.log("yo");
          this.$router.push("/lovedit");
          location.reload();
        });
    },
    hatedIt: function (list) {
      this.list = list;
      axios
        .post("/hatedits", {
          user_id: this.currentUser.id,
          movie_id: this.list.movie_id,
        })
        .then(() => {
          console.log("sup");
          this.$router.push("/hatedit");
          location.reload();
        });
    },
  },
};
</script>

您是否在此处的 if 语句中进行赋值而不是比较?

def update
    list = List.find_by(id: params[:id])
    list.movie_id = params[:movie_id] || list.movie_id
    if watched **==** true
      render json: list
    end
