Error with a link action to delete a record-CodePudding

I am creating a link to delete a record from the database, the link calls a destroy method that is responsible for doing the deletion.
Link:

<%= link_to "Eliminar el articulo", options = {:action => destroy, :id => @article.id}, html_options = {:method => :delete, :data => { :confirm => '¿Estas seguro?' }, :class => 'btn btn-danger'} %>

Routes.rb:

delete 'articles/:id' => 'articles#destroy'

Controller:

def destroy
    @article = Article.find(params[:id])
    @article.destroy
    redirect_to root_path
end

To be more concise, I would like to say that I can locate the problem in the link since what fails is :action => destroy but if I remove the link, what it does is go to the same page instead of delete the record.

The error: undefined local variable or method `destroy' for #ActionView::Base:0x000000000395d0

Try this

 = form_tag(article_path(@article), method: :delete, remote: true) do
   = button_tag(type: 'submit', class: 'btn btn-danger') do
     = content_tag(:strong, 'Delete')

destroy variable is not defined in the view... you should use a symbol instead (:action => :destroy)

<%= link_to "Eliminar el articulo", options = {:action => :destroy, :id => @article.id}, html_options = {:method => :delete, :data => { :confirm => '¿Estas seguro?' }, :class => 'btn btn-danger'} %>

However, I suggest to use the route helpers:

  delete 'articles/:id' => 'articles#destroy', as: :article
  # or user rails resources
  # resources :articles, only: [:destroy]

<%= link_to "Eliminar el articulo", article_path(@article), method: :delete, data: { confirm: 'Are you sure?' } %>
