Ruby on rails Rails显示了错误的论坛路径

我制作了属于类别的论坛模型，在每个类别的show视图中，该类别的每个论坛都需要显示，但链接指向错误的路径（例如，在类别4中，我只有一个指向类别/1/论坛/1的论坛，类别1甚至不存在）

还有一点需要注意：每个类别都有它的位置字段（整数），它们按照该字段的升序排序。类别4有位置1，但为什么那个数字会出现在url中类别id的位置上

当我尝试访问/category/4/forum/1时，出现错误“找不到'id'=1的类别”

分类控制器

class CategoriesController < ApplicationController

    def index
        categories_ordered

    def new
        @category = Category.new
        categories_ordered

    def create
        @category = Category.new(category_params)
        categories_ordered
        if @category.save
            redirect_to forums_path, notice: "Kategorija je uspešno kreirana."
        else
            render "new"
        end
    end

    def show
        find_category
        find_forums
    end

    def edit
        find_category
    end

    def update
        find_category

        if @category.update(category_params)
            redirect_to category_path(@category), notice: "Kategorija je uspešno ažurirana."

    def find_category
        @category = Category.find(params[:category_id])
    end

    def find_forum
        @forum = @category.forums.find(params[:id])
    end

部分解决了误差；我只需要在ForumsController中使用不同的参数（类别id用于类别，论坛id用于论坛）

并相应改变论坛路线

看来问题还没有解决。我更改了这部分内容，但仍然存在URL问题。现在，在url中混合了类别和论坛ID（而不是显示/category/4/forum/1/category/1/forum/4）

编辑：问题终于解决了！给了我一个应该做的想法。我只需要用路径指定@category（只需更改两行）：
