您好我創建這個種子種子 - 如何重新初始化我的種子 - 軌道
rails = Course.create(title: "Ruby On Rails")
models = rails.chapters.create(title: "Models")
models.items << Lesson.create(title: "What is Active Record?", content: "Lesson content here")
models.items << Exercice.create(title: "The Active Record pattern", content: "Exo about active record pattern")
models.items << Exercice.create(title: "Object Relational Mapping", content: "Exo about ORM")
models.items << Exercice.create(title: "Active Record as an ORM Framework", content: "Exo about ORM")
models.items << Lesson.create(title: "Convention over Configuration in Active Record", content: "Lesson content here")
models.items << Exercice.create(title: "Naming Conventions", content: "Exo about naming convention")
models.items << Exercice.create(title: "Schema Conventions", content: "Exo about schema convention")
models.items << Lesson.create(title: "Model summary", content: "Lesson content here")
models.items << Exam.create(title: "Rails Models exam", content: "Exam content here")
puts "done"
我已經做了rake db:seed
。
我的控制過程爲:
類CoursesController < ApplicationController的
def index
@courses = Course.all
end
def show
@course = Course.find(params[:id])
end
end
我控制器章:
類ChaptersController < ApplicationController的
def show
@course = Course.find(params[:course_id])
@chapter = @course.chapters.find(params[:id])
end
end
我的C ontroller章:
class ItemsController < ApplicationController
def show
@course = Course.find(params[:course_id])
@chapter = @course.chapters.find(params[:chapter_id])
@item = @chapter.items.find(params[:id])
end
end
而在應用程序/視圖/場/ index.html.erb
<div class="container-page">
<div class="padding-page">
<div class="container-fluid">
<div class="row">
<div class="col-xs-12 col-sm-12 col-md-12">
<div class="page-progress">
<h1>
Page en cours de réalisation
</h1>
<% @courses.each do |course| %>
<h2>
<%= link_to course.title, course %>
</h2>
<% end %>
</div>
</div>
</div>
</div>
</div>
</div>
但現在看來,題目的課程很多次,我想有隻看到一次。如何重置或銷燬或隱藏名稱相同且名稱相同的其他課程?
如果您想了解更多的信息,我給你,但是告訴我,我能做些什麼。謝謝。
似乎有其他記錄存在你'課程'模型,做'Course.all',然後用輸出更新你的問題 – VKatz
