Question: Hello I want to instantiate 5 objects of class Philosopher in a single line but I'm getting an IndentationError: unindent does not match any outer indentation level. Here is my source code. How to resolve this ?

```
forks=[threading.Lock() for i in range(5)]
philosopherNames={'Shubham','Nikhil','Soham','Khirade','Aditya'}
philosopher= [Philosopher(i, philosopherNames[i], forks[i%5], forks[(i+1)%5]) \ for i in range(5)]
random.seed(507129)
Philospher.running=True 
for p in philosopher:
    p.start()
time.sleep(100)
Philosopher.running=False
print "Now we are ending"

```

Answer: 
To reiterate your question, you want a link on the event page that goes to the event organiser's profile page?

```
<p>Organiser Profile</p>
<button><%= link_to "Profile", user_path(@event.user) %></button>

```
`user_path` is a path helper in Rails which resolves to RESTful route of `/users/:id`. This goes in `UserController#show` and expects `params` hash to contain `:id`. 

For your case, you are missing the argument. You need to do:

```
<button><%= link_to "Profile", user_path(current_user) %></button>

```

It automatically picks up id and passes it to params hash as : `{:id => 7}`

You may also want fix other such helpers call:

`event_path`
`edit_event_path` with appropriate argument.
