grid reloading the page on grid actions (and keeping the page's arguments)

[Vlad]

I've got a page with a grid on it. 

grid reloads the page on create and other actions. 

the page to begin with has arguments, for example, page/1/2/3. 

I want the grid to keep these 1/2/3 in place when reloading the page on those actions, for example, on new record it should use page/1/2/3/new instead of page/new. 

How do I achieve it? There must be a parameter that enables grid to keep the args, but I can't find it -

I thought it did keep track of paging. 

Are you looking for it to keep arguments that you supplied?

Yes, there are arguments on the page already. I don't want the grid to get rid of them when reloading for those actions.

So, you have to manage that yourself.

I do it kind of like this.  Yes, I know it's ugly but it pretty much works.

#  if the variable is passed in, get the value
search_text = request.get_vars.search_text

if request.wsgi.environ['QUERY_STRING'] != '':
    #  we get here if no vars were passed on the request - in
    #  this case, I want to see if I've saved a copy of them to session
    #  and if so, grab them and use them
    if not search_text:
        try:
            search_text = session['search_values']['search_text']
        except:
            search_text = ''

#  now I use search text to build the query I'm going to pass to SQLFORM.grid

#  store the current value of the variables back to your session
session.search_values = dict(search_text=search_text)

Not pretty, but it works for my use case.

I see. Thank you. 

I also did some Googling and found what I think should be documented more explicitly and perhaps more clearly in web2py docs (it's there, but unless you know what to look for, you're guaranteed to miss it):

when creating grid, the following

   args=request.args[:1]

tells the grid to keep the arguments in place and reload on top of existing one(s) - this seems to be a perfect solution by design!

Wow, way better than what I've been doing.

I'm going to have to take a look at that.

Thanks!
