In Symfony 4, I have a couple of different roles. I have a view in Twig which shows a user list. Users can have multiple roles. In the list, I want to show some text if a user has a role "MANAGER". Showing all roles is done with:

% for role in user.roles %
 role 
% endfor %

Now if the user has the role "MANAGER" I want to show some text. I tried:

% for role in user.roles %
 % if (role is "MANAGER") %
 Show some text.
 % endif %
% endfor %

but this returns the error

Unexpected token "string" of value "MANAGER" ("name" expected).

Same error is shown when I use % if is "MANAGER") % and when I use % if "MANAGER") % for some reason Show some text. is shown for every role the user has, no matter which role that is. What am I doing wrong?

As an answer to your self posted answer: a single role is not an array, the containment operator (see https://twig.symfony.com/doc/2.x/templates.html#containment-operator) supports checks for substrings as well, that's what happening here.

So you check works, but might have false-positives if you have for example a role "MINI_MANAGER", e.g.

% set role = "MINI_MANAGER" %
% if "MANAGER" in role %
 Some text here.
% endif %

will also output "Some text here.". So the better solution would be:

% for role in user.roles %
 % if role == "MANAGER" %
 Some text here. 
 % endif %
% endfor %

This could still lead to problems when role is the boolean value "true" (that is not a Twig problem, but normal PHP behavior), so you can also have a look into the "same as" test, see https://twig.symfony.com/doc/2.x/tests/sameas.html

% for role in user.roles %
 % if role is same as("MANAGER") %
 Some text here. 
 % endif %
% endfor %

So it seems I have figured it out. It seems every single role is in fact an array, so you have to check for the value within the array like this:

% for role in user.roles %
 % if "MANAGER" in role %
 Some text here. 
 % endif %
% endfor %

I am still not sure why a single role is an array though, but there surely is a reason for that.

What about this?

% if is_granted('ROLE_MANAGER') % 
 Some text here 
% endif %

Roles: When a user logs in, they receive a set of roles (e.g.
ROLE_ADMIN).
