Why am I getting an error? (syntax error, unexpected '=', expecting end)

Question

This is the errors I am getting:

syntax error, unexpected '=', expecting end @subscripting.send(name) = false ^

Here is my code:

View

<% if @subscripting.send(service.name) == true %>
    <p>done</p>
    <p>password<%= service.password %></p>
    <%= link_to "cancel", cancel_path(service_name: service.name), :method => :post %>
<% else %>

controller

def cancel
    name = params[:service_name]
    @subscripting = Subscripting.find_by(user_id: @current_user.id)
    @subscripting.send(name) = false
end

Thank you very much for answer and help.

Answer 1

When using Object.send you pass arguments to the method as secondary arguments. See documentation https://ruby-doc.org/core-2.7.1/Object.html#method-i-send

So instead try:

def cancel
  name = params[:service_name]
  @subscripting = Subscripting.find_by(user_id: @current_user.id)
  @subscripting.send(name, false)
end    

But if params are coming from some user input this could be dangerous and you should consider using Strong Parameters
