NameError - uninitialized constant

Question

I'm using Ruby on Rails 4 and my project is about an HR App. An employee can create a leave request through his profile page BUT instead I create the form in his profile page, I only wanted to create a link_to the requests controller BUT I've got this error:

NameError in Employees#show Showing /home/user/workspace/hrapp/app/views/employees/show.html.erb where line #50 raised:

uninitialized constant Requests’

Extracted source (around line #50):

48 </p>
49 <%= link_to 'Edit', edit_employee_path(@employee) %> 
50 <%= link_to ‘My Annual Leave Requests’, controller:'requests' %>
51 <%= link_to 'Back', employees_path %>  

AND I tried this solution: https://hackhands.com/rails-nameerror-uninitialized-constant-class-solution/

BUT it didn't work and I didn't find a generic answer for this error.

Here is the rake routes:

user@snf-34155:~/workspace/hrapp$ rake routes

         employee GET    /employees/:id(.:format)                            employees#show
                  PATCH  /employees/:id(.:format)                            employees#update
                  PUT    /employees/:id(.:format)                            employees#update
                  DELETE /employees/:id(.:format)                            employees#destroy
             root GET    /                                                   welcome#index

I think I just need to write the right route but I tried few of them and it didn't work anyway.

Please, can anybody help?

Thanks in advance :)

app/controllers/requests_controller.rb

Answer 1

From the code you posted

</p>
<%= link_to 'Edit', edit_employee_path(@employee) %> 
<%= link_to ‘My Annual Leave Requests’, controller:'requests' %>
<%= link_to 'Back', employees_path %>  

It seems that the ‘My Annual Leave Requests’ is using special quote characters. Did you by any chance copy and paste that from another source?

A fix I can see is manually changing the quotes to using double quotes "

I noticed your error uninitialized constant Requests’ also contains a quote at the end. Have you try fixing the controller:"requests" as well?
