cakephp - View link if depended on user rights -

-

i working cakephp 2.x. have 3 columns:

user | course | usercourserole

each user can edit multiple courses , 1 course can edited multiple users. far good.

if user wants see index of courses i want show 'edit'-link next courses can in fact edit. how can realize this? figured have set sort of field inside coursecontroller , check field inside view. right way go?

my current code is

coursecontroller.php

... public function index() {         $courses = $this->course->find('all', array('recursive' => 2));           $this->set('courses', $courses);     } ...

courses/index.ctp

<!-- file: /app/view/courses/index.ctp --> ... <?php foreach ($courses $course):?>     ...     <?php          echo $this->html->link('edit', array('action' => 'edit', $course['course']['id']));         ?>    ...

in beforerender() or beforefilter() set $this->auth->user() variable view, example userdata.

$this->set('userdata', $this->auth->user());

implement (auth)helper uses variable (you can make configurable helper setting) , checks like:

if ($this->auth->hasrole($course['course']['role']) { /* ... */ } if ($this->auth->isloggedin() { /* ... */ } if ($this->auth->isme($course['course']['user_id']) { /* ... */ }

implement hasrole() method according whatever specific requirements are.

doing helper bunch of advantages, easy reuse, overload , adapt whatever checks , don't use component in view plus should avoid calling statics , singletons lot in app. pretty easy read , understand code does.

python - TypeError: can only concatenate tuple (not "float") to tuple -

-
i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
