[web2py:14670] Re: Cacheing makes web2py "forget" tenmplates sporadically

[Timothy Farrell]

The first argument in your cache decorator ( request.env.path_info ) is the key that the cache system uses to determine uniqueness.  If you have a form in your view, then you need to insert all levels of uniqueness into this key.  Perhaps something like this... cachekey = str(request.env.path_info)+str(dict(request.vars))+str(request.args) @cache(cachekey,time_expire=20,cache_model=cache.disk) would do the trick.  If the page is restricted based on authentication, you'll also need to include some sort of unique user identification in the cachekey variable. -tim voltron wrote: Thanks Massimo, The web2PY generic template is not displayed anymore. BUT I have a more serious problem, forms rendered in the cached view function are not validated and do not work anymore. Any ideas?

Correct your code as @cache(request.env.path_info,time_expire=20,cache_model=cache.disk) def index():     """ This action renders the feedback form """     response.view = "parents_normal_form.html"     ....     return response.render(dict(....))  ### this renders the template before caching.

If someone wanted to cache the rendered view, how would they do that? -tim mdipierro wrote:Because you override the view in the action which is not executed when cached. To fix it, outside the index function add if request.function=='index': response.view = "parents_normal_form.html" Massimo On Jan 6, 10:07 am, voltron<nhy...@googlemail.com>wrote:I used disk and RAM, like I mentioned above, no errors except that it shows web2pys generic template instead of the one I declared On Jan 6, 3:49 pm, mdipierro<mdipie...@cs.depaul.edu>wrote:Do you get the error using cache.ram instead of cache.disk? How does the problem manifest? Do you get an empty page? An error? Can you add a print statement to check whether the controller is executed when you see the error?Why are you using cache.disk over cache.ram? The former involved picklying so the latter is much faster.massimoOn Jan 6, 8:09 am, voltron<nhy...@googlemail.com>wrote:Here is an example:@cache(request.env.path_info,time_expire=20,cache_model=cache.disk) def index(): """ This action renders the feedback form """ response.view = "parents_normal_form.html"page_title = T("Feedback") page_content = """On Jan 6, 3:07 pm, mdipierro<mdipie...@cs.depaul.edu>wrote:Can you provide an example of how you caching a page so that I can try reproduce this?MassimoOn Jan 6, 6:19 am, voltron<nhy...@googlemail.com>wrote:I have a bad problem at the moment, all the views that use cacheing sometimes default to web2py generic template sporadically then are then correct after a refresh.
