Solve the following python programming problem given the following code:
@ pytest.mark.parametrize ('with_signature', [True, False]) 
def test_redirects_to_real_file_url(self, db_request, with_signature) : 
    project = ProjectFactory.create () 
    release = ReleaseFactory.create (project = project) 
    file_ = FileFactory.create (release = release, filename = '{}-{}.tar.gz'.format (project.name, release.version), python_version = 'source', size = 27, has_signature = with_signature) 
    expected_filename = (file_.filename if (not with_signature) else (file_.filename + '.asc')) 
    db_request.matchdict ['path'] = 'source/{}/{}/{}'.format (project.name [0], project.name, expected_filename) 
    @ pretend.call_recorder 
    def route_path(name, path) : 
        path = ('/packages/ab/ab/thisisahash/' + file_.filename) 
        if with_signature : 
            path += '.asc' 
return path 
db_request.route_path = route_path 
    resp = file_redirect (release) 
    assert isinstance (resp, HTTPTemporaryRedirect) 
    assert (resp.headers ['Location'] == ('/packages/ab/ab/thisisahash/' + expected_filename)) 
    assert (route_path.calls == [pretend.call ('packaging.file', path = (file_.path if (not with_signature) else file_.pgp_path))]) 

    
    

    Fix the buggy line: resp = file_redirect (release)
assistant
#Here is Python program to fix the buggy line: resp = file_redirect (release)
.

resp = file_redirect (db_request)
