integrity error with transaction middleware, django 1.3

I'm getting duplicate entry integrity errors when saving an object, with transaction middleware enabled in django 1.3. I thought the point of the middleware was to rollback transaction errors and retry the view. Why would I be getting this error? The db is mysql. The save code looks like this: t

serialize field name instead of "pk"

Looks like a m2m class can be identified by the ._meta.auto_created attribute, which also holds the class with the m2m field. So the router can check for attributes on that class. On Wed, Jan 4, 2012 at 11:49 AM, Brian Craft wrote: > I strongly suspect the problem I'm having has to

I have two models. The second one has a ManyToMany to the first. Both are managed. If I drop both tables and run syncdb, only the two model tables are created. There's no join table. syncdb doesn't report any errors. "validate" shows 0 errors. Any ideas what the problem could be, or how to debug i

I don't think so. It's not issuing a redirect. It's just serving the view, even though the url spec doesn't match. On Thu, Dec 1, 2011 at 2:42 PM, creecode wrote: > Hello Brain, > > Could it be you are seeing the results of the APPEND_SLASH setting < > https://docs.djangoproject.com/en/1.3/ref/se

double trailing slash in url

I have a url spec like so: (r'^foo/$', 'blah') I just noted from our server logs that if someone mistakenly types two slashes ('foo//'), the page gets served, but all of the relative links are broken. It's really confusing. I believe it should be redirecting or 404ing instead. I note that foo/bar

default group for new users

Is there a good way to add new users to a default group when they are created (e.g. via django-registration)? I just tried binding the post_save signal for User, and adding the group in the signal handler (if "created" is true). However, I haven't found a good place (file) to put the connect() call

It's in a cookie once you coerce django into sending the cookie to the browser. This is less automatic for ajax apps, because django isn't serving the forms (which is when it usually sends the csrf cookie). On Mon, Mar 21, 2011 at 9:49 AM, Matt Robenolt wrote: > To get the token? It's stored in

Yeah, I'm using that technique. It works fine once you have the cookie. My question was about how to get the cookie, which is not described well in the documentation. Manually calling get_token() in the view for the first ajax GET seems to be working. After that I can POST to other views. On Sat,

I notice that the csrf token is not secure, i.e. the Set-Cookie is constructed w/o the "secure" option, so the browser will send it in-the-clear. It's trivial, then, for a 3rd party to discover the csrf token. Am I missing something? -- You received this message because you are subscribed to the
