Error in part 4 of the tutorial?

[simon_k]

I am pretty sure I was following *exactly*

tutorial url: ​http://docs.djangoproject.com/en/dev/intro/tutorial04/#intro-tutorial04

The (apparent) error in code shown at the top of the page (the template for the "simple form")

(Reformatted description, please use the preview button and WikiFormatting.)

The problem is you are using the latest-development-level docs with a released level of the code, which does not have some of the recent changes introduced in trunk. Specifically, csrf_token does not exist in 1.1.1 or earlier. You can fix the problem you see by just deleting it from your template.

The 1.1 level of the tutorial part 4 is here: ​http://docs.djangoproject.com/en/1.1/intro/tutorial04/#intro-tutorial04

(The problem of there being no link to the 1.1.1 docs is covered by #12155.)
