    <p>I'm testing my Flask app.</p> <p><strong>In summary, here is my question(s):</strong></p> <p>1) My final url assertion in the block of code below fails. According to Twill, it fails because the actual url is '/auth/login'. In other words, the user was NOT redirected to the protected admin page. Why?</p> <p>2) How can I include the "/?next='admin'" request argument in my url assertion? In other words, is there a way--via Twill or any Pythonic means--to test the 'next' argument resolved correctly?</p> <p>3) In functional testing, is there any other way to show a redirect works beyond just asserting a 301 status code?</p> <p><strong>Here's the Twill related part of my script...</strong></p> <pre> t.browser.go(t.url("/auth/login/?next=%2Fadmin%2F")) url("/auth/login/?next=%2Fadmin%2F") </pre> <p>Here's the resultant traceback:</p> <pre> TwillAssertionError: current url is 'http://127.0.0.1:5000/auth/login/?next=%2Fadmin%2F'; does not match '/auth/login/?next=%2Fadmin%2F' </pre> <p>NOTE: Weirdly, asserting a 200 status code after the 'go' command does not return any kind of error. I'd like to show that, after logging into the above URL, that the final URL is, indeed, the admin page. Like so...</p> <p><strong>The test I'd like to run without any fails, but can't...</strong></p> <pre> def test_redirect_via_url(self): with Twill(self.app, port=8080) as t: #: go to admin page before logging in... t.browser.go(t.url("/admin")) #: assert admin url redirected to login url url('/auth/login') #: The above assertion works, but... #: why can't I assert this URL..a 'next' argument...? #: "/auth/login/?next=%2Fadmin%2F" #: that's what actually appears in the browser's address bar #: In any regard, at the '/auth/login' url, let's login fv("1", "username", "test") fv("1", "password", "welcome1") submit() #: Now I want to show my app actually redirects to the protected admin page... #: which should have a URL of localhost/admin url('/admin') #: The above url assertion fails. The actual url after submit is still '/auth/login' </pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
