link_to expecting keyword_end rails - ruby

Question

i don't understand why but i still have a problem when following the ruby on rails tutorial. It's when you put the links on to navigate between the different page..
this is my view:
<h1>New Article</h1>
<%= form_for #article, url: articles_path do |f| %> <!<%= form_for :article, url: articles_path do |f| %> >
<% if #article.errors.any? %>
<div id="error_explanation">
<h2>
<%= pluralize(#article.errors.count, "error") %> prohibited
this article from being saved:
</h2>
<ul>
<% #article.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<p>
<%= f.label :title %><br>
<%= f.text_field :title %>
</p>
<p>
<%= f.label :text %><br>
<%= f.text_area :text %>
</p>
<p>
<%= f.submit %>
</p>
<%= link_to 'Back', articles_path %>
and this is my controller
class ArticlesController < ApplicationController
def new
end
def create
#article = Article.new(article_params)
if #article.save
redirect_to #article
else
render 'new' #on utilise render car cela permet de recharger la requête d'article
#qui vient d'échouer contrairement à redirect_to qui lancerais une nouvelle requete
end
end
def index
#articles = Article.all
end
def edit
end
def show
#article = Article.find(params[:id])
end
def update
end
def destroy
end
end
private
def article_params
params.require(:article).permit(:title, :text)
end
if you need some over tell me.
So if you have any tips, thanks a lot

Answer 1

Its not the link that is expecting end keyword. The actual error is due to no end tag to the form.
Please update yours as below
<h1>New Article</h1>
<%= form_for #article, url: articles_path do |f| %> <!<%= form_for :article, url: articles_path do |f| %> >
<% if #article.errors.any? %>
<div id="error_explanation">
<h2>
<%= pluralize(#article.errors.count, "error") %> prohibited
this article from being saved:
</h2>
<% #article.errors.full_messages.each do |msg| %>
<ul>
<li><%= msg %></li>
</ul>
<% end %>
</div>
<% end %>
<p>
<%= f.label :title %><br>
<%= f.text_field :title %>
</p>
<p>
<%= f.label :text %><br>
<%= f.text_area :text %>
</p>
<p>
<%= f.submit %>
</p>
<%end%>
<%= link_to 'Back', articles_path %>

Answer 2

It seems you have not initialized your #article variable in the new action.
In your new action write it as #article = Article.newand it should work fine.
As you have not initialized #article, it gives you a nil value error in the form.

Answer 3

Thanks for your quick answer, and i did what you told me to do. In fact I missed the end in the form. But now a new error comes which points the "heading" line 2:
Error message:
"First argument in form cannot contain nil or be empty"
The new code
<h1>New Article</h1>
<%= form_for #article url: articles_path do |f| %>
<% if #article.errors.any? %>
<div id="error_explanation">
<h2>
<%= pluralize(#article.errors.count, "error") %> prohibited
this article from being saved:
</h2>
<ul>
<% #article.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<p>
<%= f.label :title %><br>
<%= f.text_field :title %>
</p>
<p>
<%= f.label :text %><br>
<%= f.text_area :text %>
</p>
<p>
<%= f.submit %>
</p>
<%end%>
<%= link_to 'Back', articles_path %>
Can you find the bug. I would like to improve myself in Ruby and Ror.
Thanks a lot
