Question

In ruby on rails i want to show user's articles. Here is my articles_controller.rb
class ArticlesController < ApplicationController
before_action :set_article, only: %i[ show edit update destroy ]
before_action :authenticate_user!, except: [:index, :show ]
before_action :correct_user, only: [:edit, :update, :destroy]
# GET /articles or /articles.json
def index
#articles = Article.all
end
def myarticles
#articles = Article.all
end
# GET /articles/1 or /articles/1.json
def show
end
# GET /articles/new
def new
##article = Article.new
#article = current_user.article.build
end
# GET /articles/1/edit
def edit
end
# POST /articles or /articles.json
def create
##article = Article.new(article_params)
#article = current_user.article.build(article_params)
respond_to do |format|
if #article.save
format.html { redirect_to #article, notice: "Article was successfully created." }
format.json { render :show, status: :created, location: #article }
else
format.html { render :new, status: :unprocessable_entity }
format.json { render json: #article.errors, status: :unprocessable_entity }
end
end
end
# PATCH/PUT /articles/1 or /articles/1.json
def update
respond_to do |format|
if #article.update(article_params)
format.html { redirect_to #article, notice: "Article was successfully updated." }
format.json { render :show, status: :ok, location: #article }
else
format.html { render :edit, status: :unprocessable_entity }
format.json { render json: #article.errors, status: :unprocessable_entity }
end
end
end
# DELETE /articles/1 or /articles/1.json
def destroy
#article.destroy
respond_to do |format|
format.html { redirect_to articles_url, notice: "Article was successfully destroyed." }
format.json { head :no_content }
end
end
def correct_user
#article = current_user.article.find_by(id: params[:id])
#redirect_to friends_path, notice: "Not Authorized To Edit This Friend" if #friend.nil?
redirect_to articles_path, notice: "Not Authorized To Edit This Article" if #article.nil?
end
private
# Use callbacks to share common setup or constraints between actions.
def set_article
#article = Article.find(params[:id])
end
# Only allow a list of trusted parameters through.
def article_params
params.require(:article).permit(:title, :description, :paragraph, :image, :content, :user_id)
#params.require(:article).permit(:title, :description, :paragraph, :image, :content) eskisi
end
end
in views/articles i have myarticles.html.erb
and in routes i have get 'articles/myarticles'
in myarticles.html.erb i have the same code for show.html.erb(actually i want to show the articles that belongs to that user but i will add that later):
<p id="notice"><%= notice %></p>
<div style="justify-content: center;display: flex;" >
<div style="max-width:680px;width: 100%;" >
<%# <div class="container-{680px}"> %>
<br>
<h1>
<%= #article.title %>
</h1>
<p>
<%= #article.description %>
</p>
<%# <p style="justify-content: center;display: flex;" > %>
<p style="flex-direction: column;display: flex;" >
<%if #article.image.attached? %>
<%=image_tag #article.image ,class:"img-fluid"%>
<% end %>
</p>
<p>
<%= #article.content %>
</p>
<%#
<p>
<%= #article.paragraph %>
<%# </p> %>
<br>
<%= link_to 'Edit', edit_article_path(#article) ,class:"btn btn-secondary"%> |
<%= link_to 'Back', articles_path ,class:"btn btn-secondary"%>
</div>
</div>
But i got this message:
NoMethodError in Articles#myarticles
Showing C:/Users/oem/Desktop/blog/app/views/articles/myarticles.html.erb where line #8 raised:
undefined method `title' for nil:NilClass
<h1>
<%= #article.title %>
</h1>

Answer 1

In your controller actionmyarticles you declared #articles. But in the view you are using #article. #article is available in show where is declared with the before_action callback, but not in my articles.
You probably want to show a list of articles in myarticles view so you can do something like:
<%= #articles.each do |article| %>
<h1>
<%= article.title %>
</h1>
...and so on
<% end %>
